Actually this is a good idea. Big problem with wind is that you got to have spinning backup at a real power plant in case the wind stops, and it takes hours to get a turbine up and running. Houses that have electric heat, air conditioning, and water heaters could thus function as a massive battery bank. Extra energy could heat the water another ten degrees or so, or simply warm up or cool down the houses a few degrees. When wind was a slower, the opposite could happen. The modulation wouldn’t even need to be enough to be noticed to make a huge difference.
I do the same thing personally now, as I heat exclusively with wood and have a minimal air conditioner. The temperature in my house varies probably 20 degrees over the course of a year and I don’t suffer at all. The body has adjustment mechanisms for this.
Of course if you are a girlyman who is terminally distressed by a couple of degrees of temperature change it won’t work for you.
Having said all that, I still am not sure that wind generators will ever recover the initial investment either in dollars or BTU’s. The people pushing them will not answer that question.
I still have trouble seeing how heating water a few degrees more is storing energy like a battery does. Maybe I am not looking at it right, but say the water is now warmer, but there is still the same volume of water as you had before. So, unless my appliances can intelligently use less hot water when the water is hotter, I don’t see where the energy is stored.
What am I missing?
