Energy - the power without which we cannot workWe need energy to make anything work. There are many types of energy. The energy requirements are there in each and every field. The energy got from the traditional resources are being used from very early age,. Wood and coal have been used from early ages. Now we are at a stage that we have to take care of our energy resources as the traditional source energy will soon be finished. We have now to start using the renewable sources of energy. The renewable sources of energy are that energy that can be used again and again without depleting them altogether.
The non-depleting sources of energy that are used by mankind are sun, wind, water, geothermal, etc. These sources of energy are used again and again and won't be depleted. They are used to power our homes, industries, vehicles and other small things. One very important source of energy is the bio mass. In this biological material is used to make fuel or energy. The ingredients of making biomass fuel are sugarcane, corn, wood, switch grass and algae. It is used to power vehicles and does not give large carbon emissions. If use it can help to reduce carbon emissions, lower the price of energy and also reduce the effect of global warming.
Hydroelectricity is another very important source of renewable electricity. It produces energy by using the gravity force of water when it is falling. This energy is harnessed to drive turbines and generators and it makes energy that way. The other sources of renewable energy are the wind solar and geothermal. If we use these sources of energy well won't be dependent on the fossil fuel source of energy and the world will be a cleaner place. Energy is uses in every filed and as we cannot do without it we have to look for better alternative sources of energy
