Drilling and exploration for deep resources is very expensive. Forecasts for the future of geothermal power depend on assumptions about technology, energy prices, subsidies, and interest rates. Pilot programs like EWEB's customer opt in Green Power Program [6] show that customers would be willing to pay a little more for a renewable energy source like geothermal. But as a result of government assisted research and industry experience, the cost of generating geothermal power has decreased by 25% over the past two decades.[7] In 2001, geothermal energy cost between two and ten cents per kwh.[8]

Flash steam plants are the most common type of geothermal power plants in operation today. They use extremely hot water (above 300 degrees F (149 degrees C)), which is pumped under high pressure to the generation equipment at the surface. The hot Estimated subterranean temperatures at a depth of 6 kilometers.water is vaporized and the vapor in turn drives turbines to generate electricity

Wind power is safe, clean and increasingly affordable – with the potential for production on a much larger scale.Government support is crucial in ensuring the expansion of wind power. We believe such support should be transitional and limited. In the US, there is continuing uncertainty over the renewal of the production tax credit, which provides incentives to invest in wind energy. We are working with other wind energy suppliers to make an effective case for wind energy generation and the renewal of the production tax credit.Wind farms can provide large volumes of electricity (sometimes at a lower cost than conventional power generation)

For billions of years, the sun has poured out huge amounts of energy in several forms, including light, heat, radio waves, and even x-ray. The Earth, in orbit around the sun, intercepts a very small part of the sun’s immense output. On Earth, direct sunlight is available from sunrise until sunset, except during solar eclipses. Solar collectors and modules are designed to capture some of the sun’s energy and change it from radiation into more usable forms such as heat or electricity. In fact, sunlight is an excellent source of heat and electricity, the two most important forms of energy we consume.

Hydrogen Energy Hydrogen is the simplest element. An atom of hydrogen consists of only one proton and one electron. It's also the most plentiful element in the universe. Despite its simplicity and abundance, hydrogen doesn't occur naturally as a gas on the Earth - it's always combined with other elements. Water, for example, is a combination of hydrogen and oxygen (H2O).

Hydrogen is also found in many organic compounds, notably the hydrocarbons that make up many of our fuels, such as gasoline, natural gas, methanol, and propane.

Compared to the environmental impact of traditional energy sources, the environmental impact of wind power is relatively minor, slightly higher than the environmental impact of hydro power on a life-cycle basis. Unlike electricity derived from fossil fuel-powered generating plants, wind power consumes no fuel and emits no air pollution in operation. As well, wind power consumes no fuel in operation, unlike nuclear power plants which do.

Biodiesel is an alternative fuel produced from renewable resources, such as soybeans or used restaurant grease. Biodiesel contains no petroleum, but it can be blended with petroleum diesel to create a biodiesel blend. It can be used in diesel engines with no major modifications. Biodiesel is simple to use, biodegradable, nontoxic, and essentially free of sulfur and aromatics.

Unsubsidized wind power is now cheaper than electricity produced from new coal- and natural gas-fired power stations in Australia, according to an analysis by Bloomberg New Energy Finance. The study said that electricity can be supplied from a new wind farm at a cost of 80 Australian dollars per megawatt hour, compared to 143 Australian dollars from a new coal plant and 116 Australian dollars from a new natural gas plant.
