When you are looking into renewable energy solutions that might work at your house, you have several options for how you will use the power you make. Anything you can do to offset the amount of power you buy from your utility is a good thing. The reason for that is most of the power you buy from your utility comes from non-renewable, fossil fuel driven resources. Those resources are running out. Here are the things you can do with the power you make: * Use it to charge a set of batteries * Power a small appliance * Sell power back to the grid This last way to make use of renewable energy is perhaps the one with the most potential going forward. Selling the power you make back to the broader electricity grid is a serious strategy though and it takes some technical expertise to make it happen. This is how it works: First, your utility needs to play along - you will need a "net meter", which means a way for the utility to tell how much energy you are sending back to them net of what they are sending you. Not all utilities do that yet. This is probably not something you can do yourself - it requires the services of an electrician who is experienced in grid tie-in with your specific utility. They need to know what your utility wants and needs on your side of their meter. You will get paid the utility's "avoided cost", not the price you pay for the energy you buy from them. This means that you are paid for the energy that you send to the grid based on how much it actually costs the utility to make the power they sell in that particular hour. That is very different than what you pay your house. What you pay your house is the total price of supplying that power. That includes the "wires costs" to deliver the power as well as the fuel to make it. You are not going to make a lot of money selling power back to the grid, but you can really also a lot of your costs of acquiring electricity by taking advantage of a home wind turbine kit. Selling power back to the grid can be a great strategy for someone with a lot of renewable energy from a home wind turbine kit at their disposal. It is a terrific way to make power for yourself, but also to offset the fossil fuel generated power made at a traditional power plant to the benefit of yourself and others.
