It is easy to make a wind turbine at home. Anyone with basic DIY skills could comfortably complete this simple project. So, as well as saving on their monthly electricity bills, you could also save $ 1000s on the equipment.
Many people would like to make a wind turbine but are put off by the high price of the wind turbine kits. Somehow it doesn’t make sense to spend a fortune on something that was intended to save you money! And where is the challenge in bolting together someone else’s selection of parts? If you want a proper, achievable and sustainable project, you need to do it yourself.
If you look at a wind powered generator system, it is really very simple. The main components are:
A turbine. Like a simple propeller blade. It captures the energy in the wind, and converts it to spin the rotor of a generator.
A generator. A simple device, like the alternator on your car. Produces electricity as long as the rotor is being spun.
A mounting. Something to hold the propeller in the wind stream. Ideally it should be high enough to avoid the turbulence caused by buildings or trees. And it should allow the turbine to rotate so that it always faces the wind.
Batteries. To store the excess electricity you produce, as you can’t always guarantee to produce your own power at the exact time that you want to run the washing machine!
Some simple electronics. To manage the charging of the batteries to prevent damage, and to control the power coming out of the batteries and into your home.
In fact, you don’t even need batteries. If you are already connected to the grid, you can normally sell your excess electricity back to the utility company, to build up a credit for when you need more than you can produce. In many places there are incentives to encourage you to do just that. It’s part of the utility companies’ and governments’ drive to convince us that they do care about the planet. Whether you believe that or not, there is no reason not to take their money, is there? However, due to the costs of complying with the utility company’s safety and connection standards, you may find it cheaper to start without offsetting.
