Alternative Sources of Energy
It is hard to live without Energy, but it is impossible to find another planet to live in. Energy is everything. It comes in many forms such as heat, electricity, light, mechanical energy. Conventional energy sources such as coal and oil are the main contributors to the global warming. Further more, these fossil fuels are not renewable, which means one day we will run out of them. The good news is alternative sources of energy can replace the current technologies we are using. These renewable energy sources are environment friendly as they emit less carbon dioxide, compared to fossil fuels. There are many alternative sources of energies that harness natural forces and resources such as solar power, wind power, and geothermal energy.
Energy is everything. It can be found in many forms. Fossil fuels cause many environmental issues due to the emission of carbon dioxide. However, alternative source of energy can substitute traditional energy sources with almost no negative effects on the environment. One of the alternative energy sources is solar power. In smaller scale, it is used to heat houses, water and in cooking. In larger scale, it is used to generate electricity. Another source is wind power. Older wind turbines used to grind crops, now to run generators and generate electricity. A third source is geothermal energy, in which, heated water and steam are used to run generators.
