THE TWO SOURCES OF ENERGY . Energy is the power we use for transportation purposes ,heat and light in our homes and the manufacture of all kinds of products. The two sources of energy are— a) Non-renewable energy b) Renewable energy. NON-RENEWABLE SOURCES OF ENERGY-----Most of the energy we use comes from fossil fuel, such as coal ,natural gas and petroleum. Uranium is another non-renewable source, but it is not a fossil fuel .Uranium is converted to fuel and used in nuclear power plants. Once the natural resources are used, they are gone forever. The process of gathering these fuels can be to the biomes from which they come. Fossil fuels are put through a process called combustion, in order to produce energy. Combustion creates pollution, such as carbon monoxide and sulphur dioxide, which may contribute to acid-rain and global warming RENEWABLE SOURCES OF ENERGY------ Renewable sources of energy can be used over and over again. Renewable resources include solar energy, wind, geo-thermal energy, biomass and hydropower. They generate much less pollution, both in gathering and production, than non-renewable sources of energy. Solar energy comes from the sun. SOLAR energy can be used to produce electricity through solar panel .Wind turbines, which look like giant windmills , generate electricity. Geo-thermal energy comes from the earth’s crust. Engineers extract. Steam or very hot water from the earth’s crust and use the steam to generate electricity. Biomass includes natural products, such as wood, manure and corn, These materials are burned and used for heat. Dams and rivers generate hydropower. When water flows through a dam, it activates a turbine, which run an electricity generator ( source: THE ASSAM TRIBUNE.) --------------------------------------------------------------------------------------------------------------------------.
