commendation and comentary
A 35% reduction is very commendable, but 90% by 2030 is what you are after.
My main solar electric system is 600 watts of panels on a full tracking pole mount attached to the house overhang and built for 100 mph winds. It is designed for my needs and the maximum winter sun with a three day no sun supply, and Generac 4000EXL backup. 5 hours of winter sun is 3000 W/hrs or 3Kw/hrs. I usually use 1 Kw/hr. from my added on separate garage system for this computer and my guitar amps and power tools (not used much anymore). So that is 4 Kw hrs./ day average, or 1/7th of your original. All without producing any CO2, the system had paid for itself 2 years ago (self built in 1998). Location is important, along with lifestyle changes. Cities are very inefficient and locations away from good hydro/wave, wind, and solar are especially bad. The 8 times sustainable number of people is especially bad, too. Other aspects are super-insulation using strawbales and re-used tires, and thermal mass kept warm by passive solar or wind/hydro type electric heat. I am thinking of a solarium addition to lessen the propane I use for heat. My Earthship outbuilding has the solar heat exclusively, gardens and compost toilet and solar shower with rainwater catchment, and solar power, too. It warms to 70 then goes down to 40 in the winter, 80/50 spring and fall, 70/50 in summer. 39* N Lat. 8,880' elevation.<rockon>
