Quote:The output of a wind turbine depends on the turbine's size and the wind's speed through the rotor. An average onshore wind turbine with a capacity of 2.5–3 MW can produce more than 6 million kWh in a year – enough to supply 1,500 average EU households with electricity.
Quote:Megawatts are used to measure the output of a power plant or the amount of electricity required by an entire city. One megawatt (MW) = 1,000 kilowatts = 1,000,000 watts. For example, a typical coal plant is about 600 MW in size.
600 MW / 3 MW = 200 wind mills per coal plant
Quote:On average, one kilowatt-hour of produces a little over one pound of carbon dioxide (CO2)
Quote:Beneficial use is the recycling or reuse of coal ash in lieu of disposal. For example, coal ash is an important ingredient in the manufacture of concrete and wallboard, and EPA supports the responsible use of coal ash in this manner.
Quote:Burning 4 to 8 tons of coal produces 1 ton of coal ash.
Quote:the electricity generated per ton of coal is 0.4 x 6,150 kWh or 2,460 kWh/ton.
800 lbs = 1 MWh
So 1 wind mill is worth 2400 lbs of coal (per hour) or 400 lbs of coal ash of which 2/3 is recycled.
Blades aren't recycled as yet but they are trying.
Quote:An innovative solution has also been developed to recycle blades made from glass fibre. They are crushed and mixed with other components and become an excellent solid fuel for the cement industry, replacing traditional fossil fuels, such as fuel oil as well as using the glass fibre residues within the cement matrix
