Sustainable energy is a principle in which human use of energy “meets the needs of the present without compromising the ability of future generations to meet their own needs. Sustainable energy technologies are deployed to generate electricity, to heat and cool buildings, and to power transportation systems and machines. When referring to methods of producing energy, the term “sustainable energy” is often used interchangeably with the term “renewable energy”. Costs of sustainable energy sources have decreased immensely throughout the years, and continue to fall. Increasingly, effective government policies support investor confidence and these markets are expanding. The organizing principle for sustainability is sustainable development, which includes the four interconnected domains: ecology, economics, politics and culture.
You can help by adding to it. The concept of sustainable development was described by the World Commission on Environment and Development in its 1987 book Our Common Future. In its book, the Commission described four key elements of sustainability with respect to energy: the ability to increase the supply of energy to meet growing human needs, energy efficiency and conservation, public health and safety, and “protection of the biosphere and prevention of more localized forms of pollution. Environmental criteria include greenhouse gas emissions, impact on biodiversity, and the production of hazardous waste and toxic emissions. Economic criteria include the cost of energy, whether energy is delivered to users with high reliability, and effects on jobs associated with energy production. As no source of energy meets these criteria perfectly, sustainable energy sources are sustainable only in comparison to other sources.
