Keep seeing these pronouncements by the oil companies that solar doesn’t and can’t contribute to our energy needs in a substantial way.

Clothes dryers account for 6% of the average American’s household energy budget and that’s only counting the energy it uses directly. In addition to direct energy usage, dryers take air from the house that has been heated or cooled to a comfortable temperature and expel it outdoors. Cold air which has to be heated, or hot air which has to be cooled, then comes in from outside to replace that air.

So in addition to the 6% of the households energy that they use directly they account for an even larger share when you consider the indirect costs. But here, solar power is serving that purpose.
