Energy conservation is the effort to reduce wasteful energy consumption by using fewer energy services. This can be done by using energy more effectively (using less and better sources of energy for continuous service) or changing one's behavior to use less and better source of service (for example, by driving…

An energy superpower is a country that supplies large amounts of energy resources (crude oil, natural gas, coal, etc.) to a significant number of other countries - and therefore has the potential to influence world markets for political or economic gains. Energy superpower status might be exercised, for example, by…

A power purchase agreement (PPA), or electricity power agreement, is a long-term contract between an electricity generator and a customer, usually a utility, government or company.

NRG Energy, Inc. is an American energy company, headquartered in Houston, Texas.

In energy economics and ecological energetics, energy return on investment (EROI), also sometimes called energy returned on energy invested (ERoEI), is the ratio of the amount of usable energy (the exergy) delivered from a particular energy resource to the amount of exergy used to obtain that energy…

Geothermal energy is thermal energy extracted from the Earth's crust. It combines energy from the planet's formation and from radioactive decay.
