Renewable Energy Sources For Global Use
By Dowl White
The need for renewable energy sources is becoming more and more important every day. Since the beginning of the 20th century, world has become dependent on using fossil fuels for its energy needs. Thus this great demand for fossil fuels has caused an energy crisis especially in the 1970’s. Nowadays, the situation is not too bright either with the oil barrel prices reaching $200. In addition, the pressure inflicted on the ecosystem of the world is also another factor that stimulates the need for renewable energy sources.
Renewable energy source is an energy source that can replenish itself continuously. Due to their nature, renewable energy sources are also environment friendly. There are several different types of renewable energies that can be used in the world.
- Solar Energy for Heating and Electrical Generation
- Wind Energy for Electrical Generation
- Geothermal Energy for Heating and Cooling
- Hydro energy for Electrical Generation
- Tidal Energy
- Biomass Fuels
Renewable energy is very promising to the world in creating new energy sources for global use. Especially solar energy is suited to domestic use as numerous homes across the world have solar collector panels which allow these homes to get heated and have hot water. In some cases, (if you have big enough solar panels) you can also generate enough electricity to power your home appliances through the use of photovoltaic cells.
Wind energy is also very promising, as wind farms are becoming more and more popular each day. A wind farm is construed of several wind mills that transform the kinetic energy of the wind through the mechanical motion of the rotors that transform this energy to electricity. However for using wind farms, you will need to place them on locations such as hills, and mountain tops to have enough wind to create sufficient electricity.
Geothermal energy is the harnessed by using geothermal pumps as temperature exchangers between your home and the thermal temperature of the Earth. Tidal Energy is caused by the Kinetic Energy locked in ocean waters due to tidal flows caused by the moon. As a last type of energy, you can use biomass fuels to generate heat for domestic and industrial use.
