Biomass - Renewable organic materials, such as wood, agricultural crops or wastes, especially when used as a source of fuel or energy. Biomass can be burned directly or processed into biofuels such as ethanol and methane., Energy conservation - Reducing energy consumption through using less energy and becoming more efficient in using existing energy sources., Resource exploitation - Developing and using energy resources to the greatest possible advantage, usually for profit, Energy security - Uninterrupted availability of energy sources at an affordable price., Fossil fuel - A natural fuel such as coal or gas, formed in the geological past from the remains of living organisms., Geothermal energy - Energy generated by heat stored deep in the Earth., Hydroelectric power - Electricity generated by turbines that are driven by moving water., Nuclear power - The energy released by a nuclear reaction, especially by fission or fusion. Nuclear energy uses fuel made from mined and processed uranium to make steam and generate electricity., Renewable energy sources - A resource which is not diminished when it is used; it recurs and cannot be exhausted (for example wind and tidal energy)., Solar power - The Sun's energy exploited by solar panels, collectors or cells to heat water or air or to generate electricity., Sustainable development - Development that meets the needs of the present without limiting the ability of future generations to meet their own needs., Wind energy - Electrical energy obtained from harnessing the wind with windmills or wind turbines, Sustainable energy supply - Energy that can potentially be used well into the future without harming future generations. Sustainable energy is the combination of energy savings, energy efficiency measures and technologies, as well as the use of renewable energy sources,
