Question by : What percentage of wind energy does a wind turbine convert into power? —————————————— Answer by RudydooHey Henry, good question. Actually, there has been quite a bit of work done in this area. Wind turbines this day are basically around 33% efficient. There are variations of course, the more blades a turbine has,

Question by malice: wind power; rational energy into electricity? how does wind power work? i know that the turbine blades capture wind energy and start moving, they spin a shaft that leads from the hub of the rotor to a generator The generator turns that rotational energy into electricity. but how does the generator turn

Save your money for the power bill. Yes the things work, but not enough to make up the money you spend and the equipment that must be installed to do it. On very large scale where the system is engineered it will pay off in about 18 years.

$47 won’t buy you a generator big enough to charge a battery(maybe a cell phone), what you are probably buying is an e-book on how you might be able to make a wind turbine(go to youtube and save the $47)OH my son in New Orleans has been spending $40 a day for gas for a gen. (5kva) which will barely power a room .So if you want to spend $100k you might be able to build something that might save you $50 a month if you live on a mountain top or in a tornado.

One tip that no one really thinks of is to keep everything unplugged. I heard somewhere that even when things are turned off they are still using electricity. So kitchen appliances like toasters and such that you don’t really need plugged in constantly are great candidates. Also use your desktop as minimal as possible. Those drain energy. Splurge on a thermostat that conserves energy by setting a schedule for temperature. When you are making the house really warm in the day, then kicking it in at night, it is using more energy, by having to work twice as hard.
