ENERGY SOURCES

WIND ENERGY Wind energy is created by wind turbines converting the kinetic energy in the wind into mechanical power, a generator could later be used to convert this mechanical power into electricity. An advantage of wind energy is the fact that wind energy doesn’t pollute the air like energy from a power plant or other buildings. A disadvantage is that you or anybody else can not predict the wind. Wind energy is used all over the world from farms to tall buildings.

SOLAR ENERGY Solar panels convert the suns rays into electricity by exciting electrons in silicon cells using the protons of light from the sun. One of the advantages of using solar energy is that solar energy is free but building its “collectors” cost a sizable amount of money. Another advantage of using solar energy is that it doesn't pollute the air but the solar collectors and the machines associated with things like that in turn cause pollution. Solar energy Is used around the world by common households to businesses

NUCLEAR FUSION Nuclear fusion is a nuclear reaction in which two or more atomic nuclei collide at a very high speed and join to form a new type of atomic nucleus. During this process, matter is not conserved because some of the matter of the fusing nuclei is converted in energy. One advantage of nuclear fusion is the fact that is a clean energy it does not create greenhouse gases. One disadvantage of nuclear fusion is that there is not production and there wont be until At the moment people do not use nuclear fusion for two reasons. One its very dangerous and two being that we haven’t gotten anywhere close for it to be used

HYDRO There are multiple ways to create hydro electricity but the most common way is through the use of a dam on a river. The dam stores water in a reservoir the water then gets released from the reservoir to a turbine. The turbine spins as the water flows through it turns on a generator which produces electricity. One advantage of hydro power is once a dam is constructed it produces a consistent amount of electricity. One disadvantage of hydro power is that building a dam is extremely expensive so in turn it would need to be usable for decades before it becomes profitable At the moment hydro power is a very big source of power in Canada

TIDAL ENERGY Tidal energy can be captured using a dam like hydro power but instead of collecting it in a reservoir it uses the tides to push a turbine One advantage of tidal energy is that it is a natural energy so it does not create greenhouse gases One disadvantage of tidal energy is that we can not predict the tides Tidal energy is not widely used as it is not a reliable power source
