Vertical Axis Wind Turbines - VAWT

What are Vertical Axis Wind Turbines?

A Vertical Axis Wind Turbine - or VAWT - are wind turbine generators that generate "carbon free energy" from the wind and are 90 degrees opposite of a horizontal axis wind turbine (HAWT).  More specifically, main rotor shaft of Vertical Axis Wind Turbines are situated vertically and their main components are located at the base of the turbine - at ground level.  Vertical Axis Wind Turbines have a number of advantages over horizontal axis wind turbines due to this configuration, including the location of the wind turbine's generators and gearboxes being located at/near ground-level, which makes them easier to service or repair.  In addition, VAWTs do not need directional control or "yaw control" in order to be pointed into the wind.

2-Bladed Wind Turbines are a BAD INVESTMENT 

2-bladed wind turbines are inefficient and have a low return on investment
when compared to 3-bladed wind turbines

Why 3-Bladed Wind Turbine Generators are Far Superior 
and More Efficient than 2-Bladed Wind Turbines

The argument has been settled and the debate is over. 

Today's "modern" 3-bladed wind turbines represent the latest technological improvements in wind turbine generators, and are superior to the 20-30 year old technology that 2-bladed wind turbines represent.

First of all, it is important to remember that 2-bladed wind turbines may generate only about 90% of the power of a 3-bladed wind turbine of comparable size.  While a 2-bladed wind turbine saves the weight of one extra blade when compared with a 3-bladed wind turbine, engineers of the most efficient wind turbines have determined that the extra blade used on 3 bladed wind turbines provide the optimum wind turbine efficiency and wind turbine design for the "ideal" wind turbine generators of today.  

Secondly, the top-3 leading wind turbine manufacturers have standardized on the 3-bladed wind turbine.  They do not manufacture any 2-bladed wind turbines.  Plainly stated, a wind turbine with an even number of blades (2 blades or 4 blades) are NOT of optimum design or efficiency. In fact, this debate was settled years ago when the wind turbine engineers and designers began building wind turbines over 600 kW in power output.

The leading wind turbine manufacturers and their engineers have decided that 3 bladed wind turbines are the optimum number of wind turbine blades due to the stability of the wind turbine as well as the significant wind loads and stresses placed on a 2-bladed wind turbine.  A wind turbine that has an odd number of blades is similar to a disc when calculating the computational fluid dynamics of the wind turbine.  Engineers have learned that wind turbines that have an even number of blades - such as the 2 bladed wind turbines of the past - have stability problems for a machine with a stiff structure. The reason for this problem is simple, engineers recognized that when a 2-bladed wind turbine's top blade bends backwards - when the wind turbine's 2 blades are in the vertical position - since it is now generating the maximum power from the wind - that the lower or bottom blade is now aligned with the tower and the blade is hidden or blocked from the wind - and this generates a huge amount of stress and loads on the wind turbine and its' primary components such as the bearings, shaft, transmission etc.

Because of the extreme wind loads and stresses placed on 2-bladed wind turbines, the remaining 2-bladed wind turbine manufacturers have had to resort to a "teetered hub" that helps remove some of the stress and loads placed on 2-bladed wind turbines. While there are some very fine 2-bladed wind turbines, of smaller power output, the bottom line is, 3 bladed wind turbines are inherently better and more efficient than 2-bladed wind turbines.

For these reasons, community wind farm owners and developers, along with utility-scale wind farm owners and developers, would be wise to only consider 3-bladed wind turbines.

The Ultimate Online Resource for 
Renewable Energy Project Development

• The U.S. added nearly 1,400 megawatts of new wind energy capacity during the second quarter of 2008. 
  

• New wind turbines this year will generate 7,500 megawatts of additional electricity which surpasses the 5,249 megawatts installed in 2007.
  

• Wind power accounted for more than one-third of the new electric generating capacity installed in the U.S. in 2007.
  

• The wind industry is projected to grow at a 45 percent pace for the second straight year.
  

• For every megawatt (MW) of wind energy produced, $1 million in economic development is generated. This includes revenue from planning, construction, etc. 
  

• Wind energy revitalizes rural communities by providing steady income through lease and royalty payments to farmers and other landowners.
  

• Supplemental income: It is estimated that the income to a landowner from a single utility-scale turbine is approximately $2000 per year. For a 250-acre farm with income from wind at $55 per acre, this translates into an annual income from wind leases of $14,000, with no more than 2-3 acres removed from production.
  

• Jobs: Wind energy resources bring needed jobs to rural communities and bolster farm incomes against bad weather. Worldwide, wind and solar industries are likely to be one of the main sources of new manufacturing jobs in the 21st century.
  

• Wind energy costs for consumers are low and stable. This is particularly beneficial for those on fixed incomes.
  

• As wind energy production becomes more efficient, costs will decline, while fossil fuel prices are expected to rise. 
  

• Wind energy is a widespread, inexhaustible resource: 46 of 50 states have wind resources that could be developed.
  

• WIND ENERGY GENERATES CARBON FREE ENERGY & POLLUTION FREE POWER!  Power generated from the wind reduces smog and eliminates a major source of acid rain.  Wind energy has the potential to reduce Carbon Dioxide Emissions (one of the most potent of all Greenhouse Gas Emissions) by 1/3 in the U.S. and world Carbon Dioxide Emissions by 4%! 
  

• Potential for growth: Development of just 10% of 10 of the windiest states could provide more than enough energy to displace emissions from coal-fired power plants.
  

• Cleaner air means healthier air, especially for people with respiratory disabilities.
  

Wind Power Generation vs. Traditional Power Generation

Power generated from clean, green wind energy avoids numerous negative effects of traditional electricity generation from fossil fuels:

• Emissions of mercury or other heavy metals into the air

• Emissions associated with extracting and transporting fuels

• Lake and streambed acidification from acid rain or mining

• Water consumption associated with mining or electricity generation

• Production of toxic solid wastes, ash, or slurry

• Greenhouse Gas Emissions

The benefits of wind power generation go on - including the leading role wind energy provides in reducing Carbon Dioxide Emissions into the atmosphere - the leading cause of climate change and global warming.  

Today, Carbon Dioxide Emissions in the United States approaches 6 billion metric tons/year.  

39% of these Carbon Dioxide Emissions are produced when electricity is generated from fossil fuels.

If the United States obtained 20% of its electricity from wind energy, the country could avoid putting 825 million metric tons of CO2 annually into the atmosphere by 2030, or a cumulative total of 7,600 million metric tons by 2030.

A relatively straightforward metric used to understand the carbon benefits of wind energy is that a single 1.5 MW wind turbine displaces 2,700 metric tons of CO2 per year compared with the current U.S. average utility fuel mix, or the equivalent of planting 4 square kilometers of forest every year according to AWEA 2007.

What is a Wind Resource Assessment?

A Wind Resource Assessment is defined as the process of characterizing the wind resources, wind characteristics and the site's wind energy potential for that specific site or geographical area.

NOTE:  FOR QUALIFIED LAND/RANCH OWNERS, WITH PROPERTY LOCATED IN AREAS WE ARE DEVELOPING NEW WIND FARMS, WE CAN  PERFORM THE WIND RESOURCE ASSESSMENT.

Wind Power Generation Saves Water!

20% of our nation's electricity requirements can be generated with wind power generation by the year 2030 according to the Department of Energy. 

When we do, our nation will save over 4 Trillion gallons of water through 2030 through the displacement of typical electric power plants, such as fossil fuel power plants, that would have used vast amount of water. By switching to wind power generation for 20% of our nation's electrical requirements, we reduce overall water consumption by 17% in 2030.

See our website at:  www.WindPowerGeneration.com  for more information.

_______________________________________________________

The Economic and Environmental Benefits of Wind Power

According to the Department of Energy, our nation's electricity generation from wind power alone could top 20 percent of the total power generation mix by 2030. 

This would have the economic benefits of creating 500,000 jobs and generate more than $400 billion. 

Wind Power also reduces Greenhouse Gas Emissions and other pollution by 25 percent than otherwise.

Laminations are made of thin strips of materials that make good temporary magnets and poor permanent magnets, and each strip is insulated electrically from the next. 

Leading Edge - The edge of a blade that faces toward the direction of rotation. 

Leeward - Away from the direction from which the wind blows. 

Lenz Effect - See also Eddy Currents. From H.F.E Lenz in 1833. Electromotive force is induced with variations in magnetic flux. It can be demonstrated physically in many different ways--for example dragging a strong magnet over an aluminum or copper plate, or shorting the terminals of a PM alternator and rotating the shaft by hand. Laminates are used to reduce power losses from this effect. 

Lift - The force exerted by moving air on asymmetrically-shaped wind generator blades at right angles to the direction of relative movement. Ideally, wind generator blades should produce high Lift and low Drag. 

Live - A circuit that is carrying electricity.  

Load - Something physical or electrical that absorbs energy. A wind generator that is connected to a battery bank is loaded. A disconnected wind generator is NOT loaded, so the blades are free to spin at very high speed without absorbing any energy from the wind, and it is in danger of destruction from overspeeding. 

Losses - Power that is harvested by a wind generator but is not transferred to a usable form. Losses can be from friction, electrical resistance, or other causes.

Magnetic Circuit - The path in which magnetic flux flows from one magnet pole to the other. 

Magnetic Field - Magnetic fields are historically described in terms of their effect on electric charges. A moving electric charge, such as an electron, will accelerate in the presence of a magnetic field, causing it to change velocity and its direction of travel. An electrically charged particle moving in a magnetic field will experience a force (known as the Lorentz force) pushing it in a direction perpendicular to the magnetic field and the direction of motion. Also called magnetic flux. 

Maximum Energy Product - Determines how good a magnet that different materials can make. Technically, the amount of energy that a material can supply to an external magnetic circuit when operating within its demagnetization curve.

E=I*R (voltage(E)=amperage(I)*resistance(R)), and all of the algebraic variations of this (I=E/R, R=E/I). Also, for DC circuits, Watts=Volts*Amps. For AC circuits, Watts=Amps * Volts * Cosine of phase angle theta. 

Open-Circuit Voltage - The voltage that a alternator or generator produces when it is NOT connected to a Load. 

Parallel - In DC electrical circuits such as a battery bank or solar panel array, this is a connection where all negative terminals are connected to each other, and all positive terminals are connected to each other.

In AC circuits such as a wind generator alternator, each parallel coil is connected to common supply wires, again increasing amperage but leaving voltage the same. Opposite of Series. See also Star. 

Permanent Magnet - A material that retains its magnetic properties after an external magnetic field is removed. 

Permanent Magnet Alternator - An Alternator that uses moving permanent magnets instead of Electromagnets to induce current in coils of wire. 

PM - Permanent Magnet. 

PMA - See Permanent Magnet Alternator. 

Phase - The timing of AC current cycles in different wires. 3-phase alternators produce current that is cyclically timed between 3 different wires and a common wire, while single phase produces it in only 1 wire and a common.

Pillow Blocks - Bearings that support a horizontal shaft. 

Pitch - Setting Angle of an airfoil or blade. 

Poles - A way of picturing magnetic phenomena. All magnets are considered to be "dipoles", having both a North pole (which would point North if used in a compass) and a South pole (which would point South if used in a compass. In an alternator, generator, or motor the number of Poles is a measure of how many coils, permanent magnets or electromagnets are in the armature or stator. 

Prop - Propeller. 

Propeller - The spinning thing that makes an airplane move forward. Often incorrectly used to describe a wind turbine Rotor. 

Pulley - A device for transferring power when using Belts as Gearing. Changing to smaller or larger Pulleys changes the gear ratio, and can be used to make a shaft turn faster or slower than the shaft that is providing its power. 

Pulse Width Modulation - A regulation method based on Duty Cycle. At full power, a pulse-width-modulated circuit provides electricity 100 percent of the time. At half power, the PWM is on half the time and off half the time. The speed of this alternation is generally very fast. Used in both solar wind regulators to efficiently provide regulation. 

PWM - See Pulse Width Modulation. 

Radius - The distance between the center of a circle and the outside. 

Rare-Earth Magnets - See Neodymium-Iron-Boron magnets. 

Rated Power Output - Used by wind generator manufacturers to provide a baseline for measuring performance. Rated output may vary by manufacturer. For example, one manufacturer's 1500 watt turbine may produce that amount of power at a 30 mph windspeed, while another brand of 1500 watt turbine may not make 1500 Watts until it gets a 40 mph windspeed.  Read manufacturer's ratings statements very carefully. 

Rectifier - See Diode. 

Radial - An alternator design in which the armature magnets are attached to the outside circumference of a disc, with the stator coils mounted around the outside. 

Regulator - A device to adjust incoming power so as to avoid overcharging a battery bank. In solar power, the regulator generally just turns the solar array off when the batteries are full. With a wind generator, the regulator generally diverts all or part of the incoming power to a Dump Load when the batteries fill, thus keeping a Load on the wind generator so it will not Freewheel. 

Relay - An electromechanical switch that uses a small amount of incoming electricity to charge an electromagnet, which physically pulls down a connecting switch to complete a circuit. This allows a low-power circuit to divert the electricity in a high-power circuit. 

Resistance - The voltage per amp needed to make electricity flow through a wire. See Ohm's Law. 

Root - The area of a blade nearest to the hub. Generally the thickest and widest part of the blade. 
Rotor--1) The blade and hub assembly of a wind generator. 2) The disc part of a vehicle disc brake. 3) The armature of a permanent magnet alternator, which spins and contains permanent magnets. 

RPM - Revolutions Per Minute. The number of times a shaft completes a full revolution in one minute. 

Savonius - A vertical-axis wind turbine design by S.J. Savonius of Finland from the 1920s and 30s. Shaped like a barrel split from end to end and offset along the cut. They are drag machines, and thus give very low rpm but lots of torque. 

Series - In DC electrical circuits such as a battery bank or solar panel array, this is a connection where all the negative terminals are connected to the neighboring positive terminals. Voltage increases, but amperage stays the same. In AC circuits such as a wind generator alternator, each coil is connected to the one next to it, and so on, again increasing voltage but leaving amperage the same. Opposite of Parallel. See also Delta. 

Servo Motor - A motor used for motion control in robots, hard disc drives, etc. Generally designed more like an alternator than a standard motor, most Servos need special control circuitry to make them rotate electrically. Some can be used in reverse to generate alternating current. 

Setting Angle - The angle between the blade Chord and the plane of the blade's rotation. Also called Pitch or blade angle. A blade carved with a Twist has a different setting angle at the Tip than at the Root. 

Shaft - The rotating part in the center of a wind generator or motor that transfers power. 

Short Circuit - 1) Parts of a circuit connected together with only the impedance of the leads between them. 2) In wind generators, connecting the output leads directly together so as to heavily load a generator in high winds. This creates a "short" circuit path back to the generator, bypassing all other loads. 

Shunt - An electrical bypass circuit that proportionally divides current flow between the shunt and the shunted equipment. It also allows high current measurements with low-current equipment. 

Shunt Regulator - A bypass device for power not needed for charging batteries. When batteries are full, the regulator shunts all or part of the excess power to a Dump Load to protect the batteries from overcharging damage. 

Slip Ring - Devices used to transfer electricity to or from rotating parts. Used in wound-field alternators, motors, and in some wind generator yaw assemblies. 

Star - A coil connection scheme for 3 phase alternators and generators in which all 3 coil phases are connected in parallel--they all share a common connection. 

Start-Up - The windspeed at which a wind turbine rotor starts to rotate. It does not necessarily produce any power until it reaches cut-in speed. See Cut-in Wind Speed.

Stationary - With wind generator towers, a tower that does not tilt up and down. The tower must be climbed or accessed with a crane to install or service equipment at the top. 

Stator - The part of a motor, generator or alternator that does not rotate. In permanent magnet alternators it holds the coils and laminates. 

Tail - See Vane. The proper term is actually Vane, but Tail is commonly used. 

Tail Boom - A strut that holds the tail (Vane) to the wind generator frame. 

Tape Drive Motor - A type of permanent magnet DC motor often used as a generator in small wind generator systems. 

Taper - The change in wind turbine blade width (chord) along the length. 

Temporary Magnet - A material that shows magnetic properties only while exposed to an external magnetic field. 

Thrust - In a wind generator, wind forces pushing back against the rotor. Wind generator bearings must be designed to handle thrust or else they will fail. 

Thrust Bearing - A bearing that is designed to handle axial forces along the centerline of the shaft--in a wind generator, this is the force of the wind pushing back against the blades. 

Tilt-Up - A tower that is hinged at the base and tilted up into position using a gin pole and winch or vehicle. Wind turbines on tilt-up towers can be serviced on the ground, with no climbing required. 

Tip - The end of a wind generator blade farthest from the hub. 

Tip Speed Ratio -The ratio of how much faster than the windspeed that the blade tips are moving. Abbreviation TSR.

The carbon clock tracks total carbon dioxide emissions in metric tons since 1750.

Since 1750, humans have emitted over 5 trillion pounds of carbon dioxide into the atmosphere. Roughly half of this has ended up in the oceans where it is beginning to damage the coral reefs. The other half is still in the atmosphere and causing global warming. Each pound of CO2 takes up as much space as a 500 pound person.

The formula (which should be good for a year or two) is:
C(t) = 2.58 ×1012 + 1240×t, where t is seconds since the start of 2007.

C is tonnes (metric tons) of carbon dioxide emissions.
2205 x C gives pounds of carbon dioxide emissions.

That comes to over 43 billion tons/year or over 86 trillion pounds/year.

Carbon dioxide (2) = 1 carbon atom with 2 oxygen atoms.
Carbon has relative weight 12 and Oxygen 16.
So it takes only 12 pounds of carbon to make 12+16+16 = 44 pounds of CO2.

What is "Distributed Solar Generation"?

Distributed Solar Generation, is a form of "Distributed Generation" except that the renewable energy that is generated "onsite" (on the customer's rooftop) is through solar energy systems.

Distributed Solar Generation is the opposite of "centralized generation" wherein the electricity is generated at "central power plants" that are sometimes located hundreds of miles away from a "load center" where the customers are located. Central power plants generate electricity by burning fossil fuels or through nuclear energy. Either way, central power plants are highly inefficient - especially when they are located far from the customers buying their electricity, and in the case of fossil fuels, like coal fired power plants, are responsible for about 40% of the planet's greenhouse gas emissions.  Distributed Solar Generation produces ZERO greenhouse gas emissions.

Distributed Solar Generation - while not completely accurate, has also been referred to as; onsite power generation, dispersed generation, or decentralized energy.  

Distributed Solar Generation is a method of generating electricity and other forms of energy, such as hot water from evacuated tube collectors, from systems that are installed at the locations that the power and energy is needed - thereby eliminating the need for inefficient "central" power plants typically owned and operated by electric utility companies.  

Increasingly, more and more distributed generation systems are being installed with renewable energy technologies such as solar energy systems.

What is Rooftop PV?

Rooftop PV or rooftop photovoltaics is a form of "distributed solar generation" or "dispersed generation" except that the form of power (electricity) generated comes from photovoltaic systems.

 

Solar Electric Power Systems www.SolarElectricPowerSystems.com Solar electric power systems transform sunlight into electricity. Sunlight is an abundant resource. Every minute the sun bathes the Earth in as much energy as the world consumes in an entire year. Solar cells employ special materials called semiconductors that create electricity when exposed to light. Solar electric systems are quiet and easy to use, and they require no fuel other than sunlight. Because they contain no moving parts, they are durable, reliable, and easy to maintain. How It Works Solar cells, also known as photovoltaic (PV) cells, do the work of making electricity. Several types of solar electric technology are under development, but four—crystalline silicon (a form of refined beach sand), thin films, concentrators, and thermophotovoltaics—are illustrative of the range of technologies. Solar cells are connected to a variety of other components to make a solar electric power system. Crystalline Silicon Crystalline silicon solar cells are used in more than half of all solar electric devices. Like most semiconductor devices, they include a positive layer (on the bottom) and a negative layer (on the top) that create an electrical field inside the cell. When a photon of light strikes a semiconductor, it releases electrons (see animation). The free electrons flow through the solar cell's bottom layer to a connecting wire as direct current (DC) electricity. Some solar cells are made from polycrystalline silicon, which consists of several small silicon crystals. Polycrystalline silicon solar cells are cheaper to produce but somewhat less efficient than single-crystal silicon. A simple silicon solar cell can power a watch or calculator. However, it produces only a tiny amount of electricity. Connected together, solar cells form modules that can generate substantial amounts of power. Modules are the building blocks of solar electric systems, which can produce enough power for a house, a rural medical clinic, or an entire village. Large arrays of solar electric modules can power satellites or provide electricity for utilities. Solar Electric Power System Components In addition to modules, several components are needed to complete a solar electric power system. Many systems include batteries, battery chargers, a backup generator, and a controller so that people in solar-powered homes and buildings can turn on the lights at night or run televisions or appliances on cloudy days. Grid-connected systems don't require batteries or backup generators because they use the grid for backup power. Some remote system applications, such as those used to pump water, do not require a backup power source. Components of a typical standalone PV system using crystalline silicon technology. (Source: Solar Electric Power Association) Solar electric power systems can incorporate inverters or power control units to transform the DC electricity produced by the solar cells into alternating current (AC) to run AC appliances or sell to a utility grid. Complete systems usually include safety disconnects, fuses, and a grounding circuit as well. Thin Films Solar electric thin films are lighter, more resilient, and easier to manufacture than crystalline silicon modules. The best-developed thin-film technology uses amorphous silicon, in which the atoms are not arranged in any particular order as they would be in a crystal. An amorphous silicon film only one micron thick can absorb 90% of the usable solar energy falling on it. Other thin-film materials include cadmium telluride and copper indium diselenide. Substantial cost savings are possible with this technology because thin films require relatively little semiconductor materials. Thin films are produced as large, complete modules, not as individual cells that must be mounted in frames and wired together. They are manufactured by applying extremely thin layers of semiconductor material to a low-cost backing such as glass or plastic. Electrical contacts, antireflective coatings, and protective layers are also applied directly to the backing material. Thin films conform to the shape of the backing, a feature that allows them to be used in such innovative products as flexible solar electric roofing shingles. Concentrators Concentrators use optical lenses (similar to plastic magnifying glasses) or mirrors to concentrate the sunlight that falls on a solar cell. With a concentrator to magnify the light intensity, the solar cell produces more electricity. Today, most solar cells in concentrators are made from crystalline silicon. However, materials such as gallium arsenide and gallium indium phosphide are more efficient than silicon in solar electric concentrators and will likely see more use in the future. These materials are now used in communications satellites and other space applications. Concentrators produce more electricity using less of the expensive semiconductor material than other solar electric systems. A basic concentrator unit consists of a lens to focus the light, a solar cell assembly, a housing element, a secondary concentrator to reflect off-center light rays onto the cell, a mechanism to dissipate excess heat, and various contacts and adhesives. The basic unit can be combined into modules of varying sizes and shapes. Concentrators only work with direct sunlight and operate most effectively in sunny, dry climates. They must be used with tracking systems to keep them pointed toward the sun. Thermophotovoltaics Thermophotovoltaic (TPV) devices convert heat into electricity in much the same way that other PV devices convert light into electricity. The difference is that TPV technology uses semiconductors "tuned" to the longer-wavelength, invisible infrared radiation emitted by warm objects. This technology is cleaner, quieter, and simpler than conventional power generation using steam turbines and generators. TPV converters are relatively maintenance-free because they contain no moving parts. In addition to using solar energy, they can convert heat from any high-temperature heat source, including combustion of a fuel such as natural gas or propane, into electricity. TPV converters produce virtually no carbon monoxide and few emissions. They may be used in the future in gas furnaces that generate their own electricity for self-ignition (during power outages) and in portable generators and battery chargers. Advantages Solar electric systems offer many advantages. Standalone systems can eliminate the need to build expensive new power lines to remote locations. For rural and remote applications, solar electricity can cost less than any other means of producing electricity. Solar electric systems can also connect to existing power lines to boost electricity output during times of high demand such as on hot, sunny days when air conditioners are on. Solar electric systems are flexible. Solar electric modules can stand on the ground or be mounted on rooftops. They can also be built into glass skylights and walls. They can be made to look like roof shingles and can even come equipped with devices to turn their DC output into the same AC utilities deliver to wall sockets. These advances mean individual homeowners and businesses can relieve pressure on local utilities struggling to meet the increasing demand for electricity. More than 30 states offer grid-connected solar electric system owners the chance to save money on their energy bills by feeding any excess power their solar electric system produces into the utility grid—an arrangement called net metering. Solar power systems require minimal maintenance. They run quietly and efficiently without polluting. They are easy to combine with other types of electric generators such as wind, hydro, or natural gas turbines. They can charge batteries to make solar electricity continuously available. For utilities, large-scale solar electric power plants can help meet demand for new power generation, especially in distributed applications. A solar electric power plant is created from multiple arrays that are interconnected electronically. Solar electric plants are easier to site and are quicker to build than conventional power plants. They are also easy to expand incrementally—by adding more modules—as power demand increases. Solar electric power systems are good for the environment. When solar electric technologies displace fossil fuels for pumping water, lighting homes, or running appliances, they reduce the greenhouse gases and pollutants emitted into the atmosphere. The use of solar electric systems is particularly important in developing nations because it can help avert the expected increases in emissions of greenhouse gases caused by the growing demand for electricity in those countries. Solar electric technologies also benefit the U.S. economy by creating jobs in U.S. companies. Exporting solar electric technologies to developing nations expands U.S. markets while protecting the global environment. Disadvantages Although solar electric systems make financial sense in remote areas that lack access to power lines, they are usually more expensive than fossil fuels for grid-connected applications. This disadvantage is significant for utilities considering large-scale solar electric power plants. Although solar electricity costs considerably more than electricity generated by conventional plants, regulatory agencies often require utilities to supply electricity for the lowest cash cost. Utilities view solar electric power plants differently than they view conventional power plants. Solar electric modules produce electricity intermittently—only when the sun shines. Their output varies with the weather and disappears altogether at night. Integrating solar electricity into a utility system requires creative planning. Applications A combination of solar electric arrays and pool-heating solar collectors were used to provide power and heat to the Georgia Tech University Aquatic Center, site of the 1996 Olympic swimming competition. (Credit: Heliocol) Solar electricity has powered satellites since the dawn of the space program. It has run remote communications outposts high in the mountains and turned on the lights, kept medicines cold, and pumped water in rural areas for more than 30 years. Small solar cells are used to power wristwatches, calculators, and other electronic gadgets. More recently, solar electric systems have been used to provide supplemental power to homes and commercial buildings in cities. Solar electric technology has important roles to play in both the developing and developed worlds. From the farmer irrigating his crops in rural Mexico to an innovative lighting system for an Olympic sports arena, solar electric solutions abound. Electric utilities harness solar electricity for distributed applications—near substations or at the end of overloaded power lines, for example, to avoid or defer costly line upgrades. They use solar electricity during hot, sunny periods when the demand for air conditioning stretches conventional power generation to its limit. The Sacramento Municipal Utility District, for example, uses large solar electric arrays as part of its power generation mix. Utilities also rely on solar electricity to power remote, standalone monitoring systems. Consumers and builders are integrating solar electric modules into their homes and offices. Innovative solar electric technologies can replace conventional roofing and facade materials in new buildings. Solar electric roofing shingles, for example, are being used in some new residences. In grid-connected applications, solar electricity supplies some of a consumer's energy needs; the local utility provides the rest. Standalone solar electric systems power a variety of applications far from the reaches of the power grid. These applications include remote communications systems such as television and radio transmitters and receivers, telephone systems, and microwave repeaters. Standalone solar electric power is also used to prevent corrosion of metal pipes, tanks, bridges, and buildings. Many remote residences worldwide use solar electricity as their source of power. For instance, more than 100,000 vacation homes in Scandinavia rely solely on solar electric technology to run lights and appliances. Villages around the world are building solar electric systems to bring electricity to their homes and local industries, often for the first time. To make the maximum use of available resources, village power is typically produced by a hybrid power system that combines solar electricity with diesel backup generators and sometimes another renewable energy technology such wind power. Villages also use standalone solar electric systems for pumping water—an application shared by rural farmers and ranchers in the United States.

How we make and distribute electricity is changing! 

The electric power generation, transmission and distribution system (the electric "grid") is changing and evolving from the electric grid of the 19th and 20th centuries, which was inefficient, highly-polluting, very expensive and “dumb.”  

The "old" way of generating and distributing energy resembles this slide:

Hubbert's Peak Oil Predictions Now Proving True?

Marion King Hubbert was a geologist and scientist who worked at Shell Oil company's research lab in Houston, Texas.  Hubbert made several important contributions to geology, geophysics and petroleum geology.  Hubbert is most recognized for the "Hubbert Curve" and " Hubbert Peak Theory" which is now referred to as " Peak Oil. 

Hubbert's life work determined that the world has a finite amount of petroleum that can be produced.  (Similarly, there is a finite amount of coal.) Many scientists and engineers believe we have reached Hubbert's "peak oil" limit.  Hubbert's espouses that when 50% of domestic crude oil production has been reached, that there will be such significant upward demand on prices of the limited supplies of oil production, that the U.S. economy will experience severe economic, social, and political turmoil.

Hubbert's Peak Oil predictions have proven to be true and this is validated as the U.S. in the early 1970's produced about 60% of its' oil demand and imported 40%.  That equation has flipped since then, because our domestic oil production has been on the decline since 1970, so now, due to our declining domestic oil production, we have to import 60% of our oil supplies, to meet our country's oil/energy demands.

The Next Oil Shock Could be the "mother" of All Oil Shocks

How severe our economic calamity and next "oil shock" will depend upon a number of factors, including when this occurs, as well as the following:

1.  the dependence of the individual country upon its own crude oil production to meet its energy needs and to subsidize consumer imports; 

2.  the rate of relative decline in crude oil production; 

3.  the degree of difficulty encountered in replacing missing energy inputs; 

4.  the degree to which our country had prepared in advance for this inevitable geological and economic calamity.

Examples of past "oil shocks" and the economic and political calamities that followed:

United States: Our peak crude oil production of domestic oil occurred in 1970; the first "oil shock" and oil crisis followed in 1973 with the Arab/OPEC Oil Embargo.

Iran: Their peak crude oil production occurred in 1974; They had their islamic revolution 1979 that overturned government and replaced it with radical islam.

Soviet Union: Their peak crude oil production was in 1989; what happened next? 
Their country disintegrated and the collapse of the Soviet Union followed in 1991. 

Indonesia: Their peak crude oil production was in 1991; their financial and government crisis followed in 1997.

Iraq: Iraq's crude oil production was in 1989; they then invaded Kuwait (for their oil) in 1991.

Using Mr. Hubbert's predictions, that beginning around 2000  we would see peak (global) oil production, then, if the country's not weaning themselves off of their oil addiction, and had not begun making the switch to renewable energy, that the negative economic and political calamities would soon follow, including ever-increasing prices of energy that is from fossil fuels. 

Now is the time to begin weaning ourselves off of fossil fuels and making the transition to and increasing the use of renewable energy. If you don't believe in climate change, or global warming, GREAT! Join us in the switch to renewable energy and a fossil-free economy!

America's Clear and Present Danger

America Has INCREASED its' Dependence on Foreign 
Sources of Energy by 50% Since 1973.

America is even more "addicted" to foreign oil today, than we were in 1973 - 1974 when OPEC, Saudi Arabia and other suppliers from the Middle-East  stopped selling us their fossil fuels, and created a significant blow to our economy.

According to Monty Goodell, Founder and Chairman of the Renewable Energy Institute, "our increased dependence and reliance on foreign energy supplies represents a Clear and Present Danger to our national security, our economy, and the lives and livelihood of every American. Energy - including the energy we use from imported fossil fuels, is the very "lifeblood" of the American economy as it is for every industrialized country.  An economy dies without it's lifeblood of energy. This Clear and Present Danger we face is far more serious than the problems related to greenhouse gas emissions.  And while greenhouse gas emissions are very serious issue, in the long-term, pales in comparison to America's vital national security interests and America's economic stability in the short term.  For this reason alone, America needs to transition away from its addiction to foreign energy supplies. And America's abundant renewable energy resources such as the energy we receive from the sun, and renewable energy technologies such as concentrated solar power (CSP) plants - can supply 100% of America's power requirements with a concentrating solar power plant measuring 75 miles by 75 miles, located in the Southwest U.S.  By generating America's power from concentrating solar power plants, America resolves its' short-term Clear and Present Danger as it relates to importing its energy from foreign countries, and the long-term problems relating to greenhouse gas emissions."

Continuing, Mr. Goodell states that "too many Americans have forgotten what happened to us in 1973, when the Arabs and OPEC brought the United States economy to a screeching halt during the OPEC Oil Embargo.  This happened because they (mainly the country of Saudi Arabia) disagreed with our foreign policy and is the reason why they "turned off the tap" of our need for their oil supplies. When Saudi Arabia and OPEC stopped the vital flow of oil to our country in 1973, they caused an "oil shock" that severely and negatively impacted our economy. 

Mr. Goodell's question for us to ponder is, "do these countries who sell us 60% of our daily energy requirements, like us and our foreign policy, or might they leverage our addiction to their fossil fuels, and turn off the tap to make us adjust or revise our foreign policy??  Like any addict, America's foreign policy may be held hostage to its addiction, and in this case, our addiction to foreign oil, may over-ride our national interests."

Have American's forgotten the gas shortages and long lines at 
their gas stations to get gas during the Arab Oil Embargo of 1973? 

"Apparently so."  Mr. Goodell states that "in 1973, America was 'addicted' and 'over the barrel' of foreign oil to the amount of 40%.  Forty percent of our energy 'needs' in 1973 came from countries - many of which didn't like us then, and I'm afraid, many of them still don't.  The difference between 1973 and today - is that today we receive 50% MORE foreign oil now than we did in 1973.  And now we know about the problems relating to greenhouse gas emissions that we didn't know then.  America needs to change course, and change course now, in terms of its' energy supplies and how we keep America's economy strong, without the threat of being held hostage to a middle-east tyrant or regime, that could once again, turn on us, and turn off our supply of foreign oil." 

Remember ????

"Sadly," Monty Goodell continues, "most Americans have forgotten the long lines of people waiting in their cars - lined up and waiting for gasoline at their nearby gas station, with lines that were many blocks long.  And, after waiting 4-5 hours, many even waiting overnight in many places, to finally take their turn to fill up their car with gasoline, only to find that the gas station had run out of gas." 

"Let me Repeat.... That was 1973 when we imported 40% of our daily energy requirements in the form of crude oil from overseas, and from foreign countries - and many of these from countries that don't like us.

Today, over 35 years later, America has yet to learn the lesson.  We cannot continue our reliance on energy from foreign countries that supply us with 60% of the crude oil that our refineries use as a feedstock for producing gasoline and diesel fuel for our cars and trucks comes from overseas. 

America is "over the barrel" and it's not our barrel, but the barrels of oil that we are addicted by and owned by other countries.  Why have we not learned the lessons we needed to learn in 1973 when we were cut-off from the vital energy supplies we need? 

Countries like China, are growing rapidly, and have an insatiable need for crude oil. China, with their booming economy, is increasingly growing in its clout and control over international supplies of crude oil - whether they do this through their ability to buy as much oil as they need on a daily basis, or whether they simply but American drilling rigs, technology, and explore and produce oil and gas from their own fields. China, is buying large amounts of oil for their country, and causing upward pricing on declining supplies. What happens if Russia, with all of their oil and natural gas, along with China and Venezuela, with or without the help of OPEC, decided to NOT sell oil to us????

To be sure, greenhouse gas emissions are a problem, and to some, greenhouse gas emissions are also a Clear and Present Danger, but not to the extent that it presents an imminent Clear and Present Danger. 

America's reliance for 60% of our energy "needs" coming from foreign suppliers is un-acceptable.

The "driver" to get America to begin reducing and eliminating fossil fuel use should be our nation's national security and the welfare and safety of its citizens. And this can all begin with developing and investing in our own renewable energy resources and renewable energy technologies, let's start by putting solar on every rooftop that has a clear and unobstructed view of the Southern sky. See www.RooftopPV.com  or  www.DistributedPV.com  for more information.  Let's create incentives begin with adopting a national "Feed In Tariff" as Germany did in 1990. 

America, we simply do NOT have the luxury of time on our hands.  We need to end our dependence and reliance on foreign fossil fuels, especially from countries that don't like us! We need to rapidly begin expanding renewable energy resources and renewable energy technologies from our vast and abundant renewable energy resources, such as; solar, solar energy systems, solar cogeneration, solar trigeneration, "solar on every roof," waste to energy, waste to fuel, biomass gasification, B100 Biodiesel, Biomethane, Synthesis Gas, geothermal, E100 Ethanol (from sugar cane and NOT from corn), and wind, where it makes economic sense."

* reduce and eventually eliminate the use of coal and other fossil fuels.

* reduce the need for inefficient and expensive central power plants owned by utility companies. 

* promote energy independence.

* end America's dependence on oil from OPEC and other countries in the Middle-East, Venezuela and end our need for importing natural gas from Russia.
