Conventional energy sources generally refer to non renewable energy resources. These energies are in use since very long time and will be ceasing within few decades. It is most important to discuss about future energy sources. Some of the conventional sources of energy are coal, petroleum, diesel, oil, electricity and natural gas. Coal is the important one among the many conventional energy sources as if this is used for various purposes like fuel for boilers, keeping the house warm, generating electricity, etc. This is also the main source of power generation in India as it contributes about 70% of the total energy consumption. Coal was formed from the dead plants and animals, which are buried deep in the earthâ€™s crust millions of years ago. Petroleum is also found in the same way as that of coal and this is a combustible fuel. Natural gas is a combustible product, which is obtained when the petrol is pumped out. Electricity is another non renewable energy on which an economyâ€™s growth depends. The country that has more abundant electricity will have a steady growth in industry, agriculture and transport.
Today, the major sources of electricity are hydropower, nuclear power and thermal power. These conventional sources of energy will not be sufficient to fulfill the future energy demands. So, we have to choose for energy forms that never ceases. Renewable energy resources are the future energy sources that will last for long. Energy forms like solar power, wind power, bio-mass, geo thermal and ocean energy are used to meet todayâ€™s power needs. Solar energy is the most widely used among the main forms of renewable energy resource. This is the purest form of energy found on earth. Unlike other non renewable energy resource, this does not emit any harmful gases in to the environment. Low or no maintenance is required as if there are no moving particles in it. Furthermore, you can be able to make huge money by selling the generated power to some other company. Domestic uses of solar energy are solar water heaters, solar oven, solar cooker, etc.
Wind energy is another form of renewable energy and ranks second after solar power. Wind mills are established near seashore to generate electricity. Wind is used to generate electricity by rotating the turbines. Wind currents are formed at seashore, where high pressure areas and low pressure areas come into contact with each other. It is highly possible to set up small wind mill at the top of the house, which is near seashore. This would supply enough electricity to light homes. If a massive wind mill is set up, then this could be used as an alternative to conventional electricity. Farmers can give their lands on lease to the government for setting the wind mill and thereby, they can generate a huge income monthly. As this takes only small amount of space, the rest of the farm land can be used by the farmer himself.
Wind turbines have advanced so much that it can produce the power up to thousands of megawatts. Power generated from water, is also used for fulfilling the energy requirements. At the early days, rivers, waterfalls were used to generate electricity. But today, dams are constructed and when the water gushes out, it spins the dynamo to produce power. This constitutes about 90% of the renewable energy. Geo thermal energy is usually produced in the volcanic areas, where the magma is very close to the earthâ€™s surface. Large power plants are set up to produce electricity. But this is not effective as other renewable energy sources. With this many renewable energy sources, you can choose the one, which best suits you.
