:) ALTERNATIVE ENERGY (: By: Mariah Meyer

There are so many different Energy's: -Wind -Solar -Oil -Gas -Hydro Electricity

I think that wind is the most important Energy because it's the easiest to make. All you need are some turbines, a windmill and generators. It creates no pollution, but solar, oil, and gas do. A bad thing about it is it takes a lot of space, and on normal days with low winds it is harder to make wind. The Wind turbines rotate and can be used to generate electricity. The amount of electricity generated from the wind, has been growing very rapidly in the recent years. A lot of the new technology has decreased the cost of producing electricity from wind. There is some advantages about wind power like the wind is free and doesn't need fuel, it doesn't produce waste, the land beneath can still be used for farm land. There is a good method that wind farms can be tourist attractions.



Another type of energy is Solar. Solar energy can be converted into other forms of energy. The two main benefits from Solar energy is that Solar energy systems does not produce carbon dioxide or air pollution. Also when Solar energy is located on buildings, they have minimal impact on the environment. Solar Energy basically means using the energy from the sun to provide electricity, to heat water, to heat or cool homes, business as well. Sunlight is a sustainable resource and is a clean, and renewable source of energy. Some advantages are that the Solar energy is free, it just needs fuel, and it doesn't produce any waste or pollution. Its very handy for low-powered uses, and it helps your home energy bills. There are a few disadvantage about Solar Energy like that it doesn't work at night, it also costs a lot to pay for all the solar power stations. Some of the disadvantages are that some days are not windy, it can be very noisy because of the generators.



Hydro Electricity is another alternative energy. Hydro Electricity is uses the energy from running water to make electrical energy. There is Hydro Electric stations that are built where there is running water. Most of those Hydro Electric stations are mostly located in dams, that's where water is stored. Those Hydro Electric stations can also be built on rivers or near waterfalls. The opening and closing gate or the pipes to the dam controls the flow of the water. A way to make Hydro Electric power is from melting snow or water from rain, which is collected and stored in a dam or a lake. This type of source is renewable source of energy. To build a dam there has to be rivers and valleys. To build a dam it has to be a great location or it will not work.The water goes through a turbine, spinning it, and activating the generator to produce electricity.
