By the way, I installed my own %26quot;windpower%26quot;. I make 400-500 KWH per month with my own turbine. I did all the work myself, for a total of $7000. I save almost $75 per month on my electric bill. It will take almost 8 years to pay for the turbine at this rate. It has a service life of 20 years and a 10 year warranty. Mike 0% 0 Votes
First, I do not know where Stephen M. found a wind turbine for $100,000.00. Most homeowner scale wind turbines cost in the $6000 to $15,000 range...depending on their output and how much of the work you do yourself. (you need to build a foundation, run wiring, etc.)
What Mike has is what is known as a %26quot;grid tie%26quot; system. If he is producing electricity on a good windy day, and not using all that he is producing, his electric meter spins backwards. The power company is required by law to buy his excess power from him. The power company does not have to pay you the same amount that it charges you, but it does have to pay you for the juice. If you pay 15 cents per Kilowatt Hour (KWH), the power company might pay you 3 1/2 cents per KWH. This is an example, not a hard and fast rule. Grid tie is the easiest way to get into producing your own electricity.
If you want to go %26quot;off grid%26quot;, then you need batteries to get you through a low wind period...which might last several days. You also need an inverter to convert the electricity stored in the batteries (DC power) to AC power to run appliances like a refridgerator, fan, lights, etc. Some people do this because they want to be free of the utility company, others because where they want to build is a long way from power lines and it will cost major bucks to get it pulled into them, and still others because they want to build way the heck and gone away from anyone else. If you want to go off grid, you are looking at $20,000 at a minimum to get set up, and very likely more than that.
On the other hand, there is commercial scale wind turbines. I work on 1.5 Megawatt wind turbines. These machines cost 2 million dollars per tower, installed. The power company buys the electricity from the owners of the turbines at a fixed rate. Some will only buy what the owner says that they will produce, and any excess power produced is a bonus to the power company. These towers are 65 meters, 80 meters, and 100 meters tall, and require trained technicians to maintain them. They also require VERY large machinery to set them up.
A homeowner could be trained to maintain their own, much smaller turbine by reading the owners manual or taking a short class, 1 day long perhaps. Homeowner scale wind turbines are rated in Kilowatts, and are much smaller in size, footprint, and height than the commercial machines. Also, instead of climbing up to maintain them, the smaller ones are usually lowered to the ground somehow for maintenance.
If you switched over to wind power in an off grid manner, you would have 1 monster bill to get it started, and then no bills at all for some time. You would need to buy a few maintenance items for the machine most likely...grease, oil, etc. on a regular basis. Other than that, you would need to replace your batteries every so often...and any other components that wore out or broke.
So, to answer your question, your bills would go way up, then drop off to very low unless something wore out or broke if you went off grid. If you go with a grid tie system, you have a large expense at the front that pays back over along time. (see Mike%26#039;s post)
I do not think it is cheaper, but that depends on where you live and what source your local power company uses for most of their power. Where I live, the power company uses mostly hydro power, so we have some of the lowest power rates in the nation. If your power company uses oil burners, then it just might be cheaper.
A few final notes. You also need to check local zoning laws to see if you can build a turbine on your property...and if you have enough space to do so. The rule of thumb for this is %26quot;1, 15, 20.%26quot; You need at least 1 acre of land, you need to situate the turbine at least 15 times the the diameter of the rotor away from your house, or your neighbor%26#039;s house, and it needs to be at least 20 feet higher than the highest object within 300 feet. You also need to know if you have enough wind to make power with a turbine.
Hope this helps. D_Offio Last paragraph is paraphrased from Countryside magazine, Volume 92, Number 1 page 68. 0% 0 Votes
