You know something is wrong with the configuration of power consumption. I've got a 5000w gas (7 gal-12hrs) generator and it supposedly will only run a small 5000btu window AC, fridge, tv and few lights. It won't run my central AC and full household electric needs. I just found another site that says you need a 5kW solar array for a $200 a month electric bill.
It's this site
(> Solar Power Estimate <) that has the Power Estimates and solar kit prices. So I am a little confused as to the kW needed and if it's because the 1500kWh is an average not including PEAK usage, which may run up to 4-5kW at a time during the day.
I do agree that the home/apt builders could easily supply and install at a much lower cost every new house and commercial buildings with solar electric supply, taking essentially all new construction off the grid. It would be a major economic savings for average people, help tremendously with clean air and insuring a much safer alternative to an EMP catastrophe.
When I found out that the original Edison light bulb still burns in the Smithsonian Institute and that industry could make shoes, dishware, tires, plastics and other items that never wear out but don't because there's no "turn over" of product, then I knew our society favored greed over efficiency and waste. Look at the old cars, watches and appliances that are still able to be fixed up compared to today's throw away crap. Some bunch of smart aleck 30yr old executives with the morals of snakes figure out how to cheapen down everything for the bottom line and their quarterly bonuses.
