Global Green - WindEnergy - SolarEnergy

Different Types of SolarEnergy Systems plus WindEnergy Systems



Many power plants today use fossil fuels as a heat source to boil water. The steam from the boiling water spins a large turbine, which drives a generator to produce electricity. However, a new generation of power plants with concentrating solar power systems uses the sun as a heat source. The three main types of concentrating solar power systems are: linear concentrator, dish/engine, and power tower systems.

Linear concentrator systems collect the sun's energy using long rectangular, curved (U-shaped) mirrors. The mirrors are tilted toward the sun, focusing sunlight on tubes (or receivers) that run the length of the mirrors. The reflected sunlight heats a fluid flowing through the tubes. The hot fluid then is used to boil water in a conventional steam-turbine generator to produce electricity. There are two major types of linear concentrator systems: parabolic trough systems, where receiver tubes are positioned along the focal line of each parabolic mirror; and linear Fresnel reflector systems, where one receiver tube is positioned above several mirrors to allow the mirrors greater mobility in tracking the sun.

A dish/engine system uses a mirrored dish similar to a very large satellite dish. The dish-shaped surface directs and concentrates sunlight onto a thermal receiver, which absorbs and collects the heat and transfers it to the engine generator. The most common type of heat engine used today in dish/engine systems is the Stirling engine. This system uses the fluid heated by the receiver to move pistons and create mechanical power. The mechanical power is then used to run a generator or alternator to produce electricity.

A power tower system uses a large field of flat, sun-tracking mirrors known as heliostats to focus and concentrate sunlight onto a receiver on the top of a tower. A heat-transfer fluid heated in the receiver is used to generate steam, which, in turn, is used in a conventional turbine generator to produce electricity. Some power towers use water/steam as the heat-transfer fluid. Other advanced designs are experimenting with molten nitrate salt because of its superior heat-transfer and energy-storage capabilities. The energy-storage capability, or thermal storage, allows the system to continue to dispatch electricity during cloudy weather or at night.


You can build your own SolarEnergy "Photovoltaic Cell" System at home and even sell the power you make, if you build your system is large enough, back to the power company.
Below you will find links to two sites which will provide you with the knowledge to build a solarenergy system in your own backyard, "Home Solar Energy" 






They will also provide you with information on how to build a homemade wind turbine" to supplement the solarenergy system. "Home Wind Power" using an "homemade wind turbine" or wind powered generator is another project you can complete at home using the instruction from the links below. 


"Wind Turbine Design" for residential windpower is just one more way these links will sve you money on you "energy billing".


Check this out today and build your system in as quick as a weekend and they add to it over the course of the coming weeks and months.

Economics and Other Benefits of Active Home SolarEnergy Heating Systems

Active solarenergy heating systems are most cost-effectivehome solarenergy, when they are used for most of the year, that is, in cold climates with good solar resources and good solarenergy cells. They are most economical if they are displacing more expensive heating fuels, such as electricity, propane, and oil heat. Some states offer sales tax exemptions, income tax credits or deductions, and property tax exemptions or deductions for home solarenergy systems.
The cost of an active home solarenergy heating system will vary. Commercial systems range from $30 to $80 per square foot of collector area, installed. Usually, the larger the system, the less it costs per unit of collector area. Commercially available collectors come with warranties of 10 years or more, and should easily last decades longer. The economics of an active space heating system improve if it also heats domestic water, because an otherwise idle collector can heat water in the summer. 


You are able, through "solar panel design", such as the instructional packages below, to build your own "photovoltaic cell" making your own solarenergy panels. These panels can be portable or fixed allowing you to chose how to use your finished product.
Heating your home with an active "solarenergy power cells" "photovoltaic cell"  energy system can significantly reduce your "energy billing" in the winter. A "home solarenergy" heating system will also reduce the amount of air pollution and greenhouse gases, that result from your use of fossil fuels such as oil, propane, and natural gas for heating or that may be used to generate the electricity that you use.

The Benefits of 20% Wind Energy by 2030

According to the American Wind Energy Association, if we increase our nation's wind energy capacity to 20% by 2030, it would…

Reduce Greenhouse Gas Emissions

A cumulative total of 7,600 million tons of CO2 would be avoided by 2030, and more than 15,000 million tons of CO2 would be avoided by 2050.

Conserve Water

Reduce cumulative water consumption in the electric sector by 8% or 4 trillion gallons from 2007 through 2030.

Lower Natural Gas Prices

Significantly reduce natural gas demand and reduce natural gas prices by 12%, saving consumers approximately $130 billion.

Expand Manufacturing

To produce enough turbines and components for the 20% wind scenario, the industry would require more than 30,000 direct manufacturing jobs across the nation (assuming that 30% – 80% of major turbine components would be manufactured domestically by 2030).

Generate Local Revenues

Lease payments for wind turbines would generate well over $600 million for landowners in rural areas and generate additional local tax revenues exceeding $1.5 billion annually by 2030. From 2007 through 2030, cumulative economic activity would exceed $1 trillion or more than $440 billion in net present value terms.
