Energy derived from any renewable source; i.e other than fossil fuels or nuclear fission
Refers to a host of non-carbon based providers of fuel and electricity Clearly, the world's reliance on fossil fuels has resulted in a multitude of environmental, social, and economic problems Cleaner, cheaper, more reliable sources of energy are available for use by factories, cars and trucks, buildings Some examples include: fuel cells, solar, wind, biofuels, and waves Learn more at: Alternative Enegy Institute
Any of various renewable power sources to use in place of fossil fuels and uranium. Fusion devices (see nuclear fusion) are believed by some to be the best long-term option, because their primary energy source would be deuterium, abundant in ordinary water. Other technologies include solar energy, wind power, tidal power, wave power, hydroelectric power, and geothermal energy. The amount of energy in such renewable and virtually pollution-free sources is large in relation to world energy needs, yet at present only a small portion of it can be converted to electric power at reasonable cost
energy that is not popularly used and is usually environmentally sound, such as solar or wind energy (as opposed to fossil fuels)
Sources of energy outside the traditional use of fossil fuel which is derived from living matter and is finite
energy derived from sources that do not use up natural resources or harm the environment
Energy derived from nontraditional sources (e g , compressed natural gas, solar, hydroelectric, wind)
(énergie de remplacement) Alternative energy is generally defined as including renewable energy sources, such as biomass, small hydro, solar, wind, geothermal, tidal energy and photovoltaic conversion systems In addition, the term covers new transportation fuels (such as ethanol from renewable energy sources) and new applications of conventional energy sources (such as the use of propane and natural gas as automotive fuels, and batteries in electric vehicles)
