What Is Renewable Energy?
Renewable energy is generally defined asenergy that comes from resources which are naturally replenished on a human timescale, such as sunlight, wind, rain, tides, waves, and geothermal heat….
Still in many countries, coal, oil/petroleum and natural gas are being predominantly used for energy. These resources, which are also called as fossil fuels, are not renewable. These resources are both limited by virtue of being depleted one day and also tend to be expensive in parallel with the shortening of reserves. With the increase in their production, the environment will be damaged further.
Hydrogen, just like water, is found in most of organic compounds. It is the most abundantly found element in our earth. But, it is not gaseous in its natural state. As it combines with oxygen in order to form water, it is always compound with other elements. When resolved from its other elements, hydrogen energy may be also used as a fuel or transformed into electric power. All renewable energy resources are not originated from the sun; included energy is extricated from for a variety of uses such as heating and cooling of buildings. Tidal energy of oceans is resulted from the gravitational attraction of the sun and moon. In fact, ocean power originates from lots of sources. In addition to tidal energy, there is ocean power which ocean waves are generating in concurrence with winds and tides. Since the sun is heating ocean surface more in comparison to ocean deeps, temperature difference occasionally occurs and this difference can be used as a source of energy. All these types of ocean energy may be also used in electric power generation.
