Energy resources are subdivided into two groups: renewable resource of energy and non renewable resource of energy. Renewable resources are those that can be replenished in a short period of time, while non renewable energy resources are those which we are constantly using up and cannot create in a short span of time.
Renewable energy resources include the solar energy, wind energy, wave and tidal energy, geothermal energy, biomass and hydropower. These are clean energy resources and does not produce waste products or release carbon dioxide into the atmosphere. For instance, the solar energy is the energy from the sun which can be used to produce electricity and heat. Similarly wind and thermal energy from inside the earth can be used to produce different types of energy. However most of our energy demand is met by energy produced from non renewable energy resources such as the fossil fuels like coal, oil, natural gas. These energy resources have been formed over million of years by the action of the pressure from soil and rock on the remains of dead animals and plants and the heat from the Earth’s core. These energy resources release waste product and carbon dioxide into the atmosphere.
Energy is required to perform almost all the tasks. The non renewable energy resources are fast depleting. These energy resources should be used smartly and the government must encourage the use of alternative renewable energy resources. It provides a great alternative to the energy requirements of the people and is also environment friendly.
