windmills

[moloss]

our home is on a small hill and gets it's fair share of wind......that said the other day I was thinking it sure would be nice to have some sort of wind mill to generate some energy to decrease my utility bill.....anyhow does anybody have any expierence with them.....I don't have a clue.....Chris.

In a gale force wind, my 8' wheel is rated at the incredible 1.5 hp. The advantage of such a machine is the continuous duty if you can keep the wind up.

Best use would be water pump or a dc generator heating water.

This would give you some power. Couple hundred going up about 15 mile from me.

moloss, I've watched the wind energy scene with wishful eyes for a long time. The clues I've gathered are as follows:

You need steady wind almost 24X7 and at 15mph or better to be economically feasible.

A wind generator is quite expensive up front cost.

Electrical storage is a problem... only practical way is to feed it back into the grid and get credit from your electric company.

All the above is why you don't see wind generators hardly anywhere.

Harbor Freight has some stuff you can buy and play with. Note that its capacity is very, very small. This is a toy unless you are WAY in the back woods. This is only half a system.... once the wind starts turning, you need a way to store the energy... batteries or back into the grid... this is significant ADDITIONAL costs.

They are growing like weeds in the Texas panhandle and Dodge city Kansas area.

They really don't need much wind to keep going and that 15mph # would seem feasible since these areas have a steady flow of wind.

Agreed, when conditions are right, they can work well. You named some of the places where such conditions exist.

The OP is in Alabama and is interested in reducing HIS energy bill.... I doubt he's quite in the league of the posted generator photos.

The newer technology allows the mills to start spinning at lower speeds and turn less spins into more energy. I agree that at this time, unless you have a hybrid system with solar and batteries, the best way to do it is to have it tied into the grid and try to offset your electric bill. They are becoming cheaper and cheaper. I will probably try to do one in MI when I build my house in a few years, even though conditions aren't great. The newer ones are easier to maintain and service. I say go for it.

You'll need to know your average wind speed. Check with your local airport or get an anemometer and record the data for a year.
Check out wind generators such as:
Living with Ed - TV series on HGTV
Welcome to OTHERPOWER.COM
Pacwind
Skystream 3.7 Compact Wind Turbine and Wind Energy System

You need to check and see if your state has a law called 'net metering'. Your local utility company may know.

I just drove by the 9 they set up on the shore of Lake Erie near Buffalo yesterday. Three were in operation and the other 6 were sitting waiting for repairs to the gearboxes.

We've got about 22 of those large ones here in ne Pa. The towers are about 200' tall, and the blades are I think 130' long each. They are quite a sight. I do wish they would turn them off. It has never been so windy around here until they turned on the windmills.

You might want to check your local regulations before you even consider this. I wanted to put up a 60' tower with a wind generator on top. Our township wouldn't allow it. They called it an eyesore. Everyone is all for the environment, if it is convenient for them.
