Numerous public opinion surveys have consistently shown that the public prefers wind and other renewable energy forms over conventional sources of generation. Wind energy is a free, renewable resource, so no matter how much is used today, there will still be the same supply in the future. Wind energy is also a source of clean, non-polluting, electricity. Unlike conventional power plants, wind plants emit no air pollutants or greenhouse gases. According to the U.S.

According to the American Wind Energy Association, 1 megawatt (MW) of wind-generated power can supply electricity to approximately 240 to 300 households per year. See similar questions...

In geothermal power plants steam, heat or hot water from geothermal reservoirs provides the force that spins the turbine generators and produces electricity. The used geothermal water is then returned down an injection well into the reservoir to be reheated, to maintain pressure, and to sustain the reservoir. There are three kinds of geothermal power plants. The kind we build depends on the temperatures and pressures of a reservoir. See similar questions...

TVA currently generates electricity from a mix of fuel sources, primarily coal, nuclear and hydro (water). In 2004, plants that burn fossil fuels (such as coal) generated 61% of the electricity TVA produced, followed by nuclear power plants (29%) and hydropower plants (9%). Green power represented less than 1% of TVA's total electric generation, an amount that is expected to increase slowly as more customers enroll in Green Power Switch. See similar questions...

Clean. Geothermal power plants, like wind and solar power plants, do not have to burn fuels to manufacture steam to turn the turbines. Generating electricity with geothermal energy helps to conserve nonrenewable fossil fuels, and by decreasing the use of these fuels, we reduce emissions that harm our atmosphere. There is no smoky air around geothermal power plants -- in fact some are built in the middle of farm crops and forests, and share land with cattle and local wildlife. See similar questions...

Energy from the sun can be directly converted to electricity using solar cells, also known as photovoltaics or PVs. The solar energy knocks electrons loose from their atoms, allowing the electrons to flow through the material to produce electricity. Although individual PV cells produce only small amounts of electricity, PV modules (see "What are "PVs") are manufactured with varying electrical outputs ranging from a few watts to more than 100 watts of direct current (DC) electricity.

ISEP energy will be made available to municipal utility companies in and near Iowa, providing an affordable, environmentally friendly energy alternative. If they don’t use all of the electricity from ISEP from time to time, the remainder would be available for sale to other utilities, including major investor-owned utilities. See similar questions...

Giant blades that are mounted on a tower catch the wind and turn a shaft. The turning shaft spins a generator that makes electricity. See similar questions...

Electricity generated by the Bluewater Offshore Wind Park will be used by homes, schools and businesses that are served by Delmarva Power & Light. Cables buried about six feet below the seabed first carry the electricity to offshore transformers and then to onshore facilities, before connecting to the existing grid at onshore substations.

There are three ways, which your electrical connection can remain constant. The first is through the NET METERING PROGRAM (see below for details) the second is through a TRANSFER SWITCH. When the wind is not blowing, a transfer switch on the generator instantly puts you back on the grid with the electric company where you draw from the power company’s energy. The third is a firm power option. See similar questions...

Wind-generated waves usually have periods (time between crests) between 5 and 15 seconds. Tsunami periods normally range from 5 to 60 minutes. Wind-generated waves break as they shoal and lose energy offshore. Tsunamis act more like a flooding wave. A twenty foot tsunami is a twenty foot rise in sea level. See similar questions...

A turbine and switchgear are mounted at the top of each tower in a casing called a nacelle, and blades are attached to the turbine. The turbines use moving air to produce power by transferring the wind’s momentum to the rotor blades and localizing that energy in a single rotating shaft. The larger turbines rotate at about 15 revolutions per minute. See similar questions...

TVA provides electric power to 158 local power distributors through a network of 17,000 miles of transmission line. These local utilities deliver power to homes, businesses, and industries throughout TVA’s service area. TVA also sells power directly to 54 large industries and eight federal agencies.

Progress Energy supports innovative ways to use and conserve energy sources that protect our environment. To that end, we have procedures and tariffs that can accommodate either decision. Homeowners should carefully evaluate the various economic and technical considerations when making their choice. There are various resources (non-profit organizations, government, vendors, etc.) that provide valuable tools and information for making these decisions. See similar questions...

a renewable source, wind energy has the following generic advantages: it never runs out and does not contaminate the atmosphere. See similar questions...

A medium sized average house needs between 4-6MWh of energy per annum. In good locations one can expect wind speeds of six meters per second and on the coast they can be as high as 8 meters per second. However in urban areas, wind speeds, with lots of buildings around , you are probably looking at four meters per second and that will considerably affect performance. See similar questions...

offshore wind park will help to stabilize the price of electricity by using an energy source that is not subject to the fluctuation of market prices of fossil fuel, such as coal or natural gas. Bluewater Wind wants Delaware consumers to benefit from this price stability and we will do this by offering to sell the electricity generated at our wind park at a pre-determined price for a long-term period (20 years or more).

Most wind turbines have three blades which face into the wind; the wind turns the blades round, this spins the shaft, which connects to a generator. A generator produces electrical energy from mechanical energy. See more information here. See similar questions...

A modern wind turbine produces electricity 70-85% of the time, but it generates different outputs dependent on wind speed. Over the course of a year, a small wind turbine in the UK will generate about 20% to 30% of the amount it would generate in a constant strong wind. This is known as its 'load factor' (or 'capacity factor'). See similar questions...
