Renewable Energy and Sustainable Technologies

Sustainable Energy is the sustainable provision of sustainable energy development that meets the needs of the present without compromising the ability of future generations to meet their needs. Technologies that promote sustainable energy include renewable energy sources, such as hydroelectricity, solar energy, wind energy, wave power, geothermal energy, bioenergy, tidal power, and also technologies designed to improve energy efficiency. Costs have fallen dramatically in recent years and continue to fall. Most of these technologies are either economically competitive or close to being so. Increasingly, effective government policies support investor confidence and these markets are expanding. Considerable progress is being made in the energy transition from fossil fuels to ecologically sustainable systems, to the point where many studies support 100% renewable energy. Efficiency and renewable energy are said to be the twin pillars of sustainable energy. Topics like bioenergy, tidal power, renewable energy sources are of interest.
