Different Resources are the New

One type of renewable energy is Solar power. Solar power is energy derived from the sun. It is the most abundant source of energy on Earth. (Global Warming) Solar Power sounds cheap but its solar panel to collect the energy is very expenseive equipment and very hard to put together. The sun is very important to our planet because if their was no sun no oxygen no life on earth.The sun is always around to provide energy tothe earth and the sun wont run out for along time so our generation is okay.
Another type of renewable energy is Wind power. Wind power is the conversion of wind energy into more useful forms, usually electricity from using wind turbines. Wind energy is ample, renewable, widely distributed, clean, and mitigates the greenhouse effect if used to replace fossil-fuel-derived lightning. To make the power, the windmill captures the wind and spins a generator. The generator then produces electricity. (Global Warming) Wind energy is renewable cause wind does never die cause of the ocean trade winds. Wind is caught by big wind turbines that spins a generator that does transfer electricity to many cities.
Another type of renewable energy is Geothermal power. Geothermal uses the natural flow of heat from the earths core. About half of the available energy is from natural radiation in the earths crust and mantle. Geothermal and biomass are the only two renewable energies which need to be carefully managed in order to avoid local depletion. (Global Warming) Geothermal energy is great to use cause the heat would never be lost unless the earth blew up. Geothermal power is bad to use cause their might be a loss of the radiation energy that is coming off the magma. Geothermal power will not run out , there is a constant flow of magma under the earth's crust and in the earth's mantle.
Hydropower is the capture of the energy of moving water for some useful purpose. Prior to the widespread availability of commercial electric power, hydropower was used for irrigation, millingof grain,textile manufacture, and the operation of sawmills.(Global Warming)Hydro power is a great alternative source to use instead of our fossil fuels. Hydro power is made from running water, like Niagra Falls. There is water turbines under the water to run generators to push electricity into wires that travel to half the people in Western New York. Hydro power was used to make many things work.
