Have you ever thought about how we get the energy to run the things we take for granite every single day? There are many sources of energy that are used for transportation, heat, light, and the manufacturing of goods of all kinds. The development of science and civilization is closely linked to the availability of energy in useful forms. The seven main energy sources are fossil fuels, hydroelectric, solar power, win power, geothermal, nuclear power, and biomass energy. By harnessing the sun, wind, falling water, plant matter, and heat from the earth, energy planners expect to decrease the environmental impact on energy use.
             Most of the nonhydro renewable power comes through some form of combustion, such as the burning of biomass, landfill gas, or municipal solid waste. Little electricity comes from solar, wind, and geothermal sources. Factors that are increasing interest in renewable energy include cost advantages in niche markets, regulatory pressures, customer service requirements, fuel flexibility, and security.
             One of the biggest sources of energy is fossil fuel. Fossil fuels have served as a reliable source of heat for cooking and warmth since the beginning of history. The common fossil fuels are coal, peat, lignite, petroleum, and natural gas. Using coal as the principal ingredient can make coal gas, coke, water gas, and producer gas. Such artificial gases can be used for fuel, illuminant, and a source material for the manufacturing of synthetic ammonia. Gasoline, kerosene, and fuel oil are made from petroleum. They are mainly used for transportation if the fuel is used in a liquid form.
             Natural gas is a natural mixture of gaseous hydrocarbons found from the ground or obtained from specially driven wells. The composition of natural gas varies in different localities. It is used extensively as an illuminant and a fuel. Some geologists theorize that natural gas is a by-product of decaying vegetable matter in
