Introduction Renewable energy is energy generated by natural resources such as wind, sunlight, rain, tides and geothermal, which can be reused or supplemented. Natural energy (renewable energy) has advantages and disadvantages. Renewable energy sources reduce dependence on fossil fuels. The use of natural resources has many advantages over the use of fossil fuels, but for some people investment costs may be too high. This project emphasizes mainly the source of renewable energy and its strengths and weaknesses.
Geothermal energy uses electricity from below the surface to generate electricity. Traditional geothermal energy utilizes steam from natural sources such as geysers and pumps to the deep part of the Earth's high temperature and high pressure. Then use hot steam to drive the electric turbine. In case of volcanic geothermal energy, heat comes from "supercritical water". Researchers explained that energy from so-called supercritical water is much higher than traditional geothermal steam. When the molten rock encounters the water, extreme heat and pressure put the water in a "supercritical" state. There, it is neither water nor liquid. In this form, water can carry more energy than normal steam, which can produce up to 10 times the output of other geothermal sources.
Hydropower depends on water, a clean and renewable energy source. Renewable energy is exhausted energy. Renewable energy comes from natural resources such as wind, sunlight, rain, tides and geothermal energy (heat generated inside the earth). Non-renewable energy sources include coal, oil and natural gas. The reservoir constructed by the dam provides a large, safe and relaxing space for the community. You can enjoy the lake with boat or water skiing. Many reservoirs have fish. Near the reservoir is usually a protected natural space, and camper and hiker can enjoy the natural environment.
