New energy sources and its sustainability

It is the provision of energy that meets the demands of the present generation without compromising the ability of the future generations to meet their needs. It includes all renewable energy sources such as hydroelectricity, wind energy, solar energy, wave power, geothermal, bio energy and tidal energy. It also includes technologies that designed to improve energy efficiency. The renewable energy technologies are mainly grouped into three sectors as first, second and third generation technologies. Green energy and energy conservation techniques comes under the category of sustainable energy development. Many European countries employ these techniques in the local level. These techniques are implemented right from energy carriers such as hydrogen and liquid nitrogen carriers. The recent statistic figures show that these green sustainable energies of rapid importance as the planet earth is suffering from global warming. This sustainable energy development has got links with all the sectors of energy such as energy production, conservation, and decrease of pollution and to implement techniques that are eco friendly.
