Renewable Energy
Renewable energy comes from natural sources that are constantly and sustainably replenished. Harnessing energy from the wind, sun, water, plants, and other renewable sources will put our lovely planet on the path to a cleaner environment, energy independence, and a stronger economy. The technologies featured here can contribute to better air quality, reduce our reliance on fossil fuels and curb global warming, add good jobs to the economy and, when properly sited, protect environmental values such as habitat and water quality. Working together, all of us can help build a sustainable future for the planet.

Alternative Energy
Alternative energy is an umbrella term that refers to any source of usable energy intended to replace fuel sources without the undesired consequences of the replaced fuels. The term "alternative" presupposes a set of undesirable energy technologies against which "alternative energies" are contrasted. As such, the list of energy technologies excluded is an indicator of which problems the alternative technologies are intended to address. Controversies regarding dominant sources of energy and their alternatives have a long history. The nature of what was regarded alternative energy sources has changed considerably over time, and today, because of the variety of energy choices and differing goals of their advocates, defining some energy types as "alternative" is highly controversial. In a general sense in contemporary society, alternative energy is that which is produced without the undesirable consequences of the burning of fossil fuels, such as high carbon dioxide emissions, which is considered to be the major contributing factor of global warming according to the Intergovernmental Panel on Climate Change. Sometimes, this less comprehensive meaning of "alternative energy" excludes nuclear energy
