Sources Of Renewable Energy
It has being observed that the consumption of non renewable sources has caused more environmental damage than any other human activity. Electricity generated from fossil fuels such as coal and crude oil has led to high concentrations of harmful gases in the atmosphere. This has in turn led to many problems being faced today such as ozone depletion and global warming.
Thus alternative sources of energy have become very important and relevant in today’s world. These sources such as sun and wind can never be exhausted and are thus known as renewable. These sources cause less emission and available locally.If you don’t trust, click here earth 4 energy dvd and Know some information on renewable energy sources
The different renewable sources of energy are:
1:Solar Energy is probably the best known method. The sun is our most powerful, natural energy source. Solar energy which is sunlight, can be implemented for light, heat, cooling homes, electricity, heating water, and much more industrial processes. Most renewable energy forms are derived either indirectly or directly from the sun. For instance, the heat from sun makes the wind blow. This in turn contributes to growth of plants and trees used for biomass energy. This plays an important role in the evaporation and precipitation cycle that empowers hydro power.
2:Wind Energy. The wind is air movement that happens when warm air ascends and cooler air dashes in, replacing it. The energy of wind has been a centuries-old tool for sailing ships and driving windmills to grind up grain. Currently, wind energy is used to generate electricity via wind turbines.
3:Hydro power. The force of water flowing downstream is powerful. Water is a renewable resource itself, constantly being recharged by the evaporation-precipitation cycle. The heat from the sun causes the water in oceans and lakes to evaporate, thereby forming clouds. The most familiar part of course is the water falling back to earth as rain or snow, draining into streams and rivers that return to the ocean. The power of flowing water can be used to drive water wheels. The energy can be captured by generators and turbines and used to generate electricity.
