The need for Renewable Energy
From our day to day living energy has been part of it. We used energy almost in every aspect of our lives. From food preparations and storage, entertainment, maintenance, doing our jobs and earning a living, keeping us warm or cold and so on. Simply to say almost every appliances, equipments and machines in our homes and work requires energy. And as the number of households, buildings industrial and commercial, population; the need for abundunat energy is always a question. If a city or town is growing so fast will the current energy level will meet its demand? in this case an increase in energy should sustain that demand.
Where will those additional energy should come from?. The current sources of energy we have now are the coal fired powerplants, nuclear power plants and hydro electric power plants. And with the present source of energy coal and fossil power plants, the increase in air pollution rises rapidly. As for nuclear power plants the danger of a melt down. However there are safe sources of energy. These are renewable energy, which are gifts from nature. Generally renewable energy are sources of energy which naturally occurs and are abundant in nature.
There are several types of renewable Energy
Solar Energy – This comes from the light from the sun. Depending on the type of process used the sunlight can be converted into electricity.
Wind Energy – To take advantage of this energy man created wind mills and turbines that converts wind into electricity.
Geothermal Energy – This form of energy utilizes the heat fromm earth itself
Other renewable energy sources are tidal power from seas and oceans, and biomass from garbage
With the increased demand in energy, thus the need for supply should increase but it does not mean that we should neglect consequences to nature. Because of the increased pollutants in the air the harm of global warming is taking effect. If we are looking for additional sources of energy we should look for a safe a pollutant free as possible source of energy should be utilized. Not only that we must now start eradicating those energy sources which greatly harms our ecosystem.
