Alternative energy is going to be very important in the future. There are a lot of different forms of alternative energy. There is solar energy that is the most common alternative energy that homeowners can utilize. The cost of solar power is getting lower and lower every year. It is about half the price now compared to five years ago. Another form of alternative energy is hydroelectricity which is using water flowing to turn turbines. The turbines turning generate electricity and produces no pollution what so ever. Hydroelectricity is no viable for homeowners though since it take a big plant and a very large river to generate electricity. Luckily, there is an unlimited amount of these alternative energy sources unlike oil and coal.
The last form of alternative energy I would like to talk about is wind energy. Wind energy is from the power of wind turning large windmills. The windmills have a shaft that goes down to a turbine which is turned to produce electricity. When someone makes a field full of windmills, they are called wind farms. Wind farms are pretty common in California. Windmills can vary greatly in size from hundreds of feet to a few feet that can be mounted on the roof of a house. The bigger the windmill the more energy it can produce. My son likes to call the windmill that he sees a big fan which I think is very funny.
I think that people really need to do what they can to reduce their carbon footprint and produce as much alternative energy as possible. Governments will usually give a pretty nice rebate for purchasing alternative energy equipment. I am going to invest in a pretty large windmill for my home since I am out in the country. It looks like I should get a pretty big rebate to offset some of the cost.
