Sustainable energy development

 

Sustainable energy is a principle in which human use of energySustainable energy strategies generally have two pillars: cleaner methods of producing energy and energy conservation. 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". In general, renewable energy sources such as solar energy, wind energy, geothermal energy, and tidal energy, are widely considered to be sustainable energy sources.
