actually with the improved efficiency of solar panels, the payback is less than ten years in california
with decent sun exposure. this misses two big points. first electricity costs from non-renewables
are likely to go up faster than inflation. two, since the new law will impact new building
which is done mainly in projects, the cost to install solar would be less than an individual
home due to economies of scale. there is also the expected belief that solar installation costs will
continue to decline and/or that solar panel efficiency is likely to improve thus making the previous
numbers too conservative.
if you guys had been around 40 years ago when the federal government mandated outrageously
high fuel efficiency standards for new cars and heard the outcry from Detroit + conservatives
as to how this would kill the domestic auto industry, drive the price of new cars to unaffordable
levels, and was not attainable; then you might be more understanding and sympathetic to
California's goals here. our air is bad, but compared to the smog and pollution of 50 years
ago; it is an improvement. if you want an example of what happens when the government
puts the economy first and ignores the environment; then just look at Beijing.
