There is talk in California of subsidizing solar power. Would it work well for me to put a roof-top system on my 2000-sq-foot house? I’m thinking 10-20-30 years down the road.
I’m asking for comment on the assumptions you would have to make, and on the facts.
For instance, assuming we have cheap petroleum right now, with energy costs rising in the future; that would make the photovoltaics pay for themselves better than if energy costs stay flat.
This thread discusses photovoltaics to some extent, but I’m confused about it.
For instance, making PVs is expensive energy-wise; how does the cost compare to setting up an array of mirrors and using steam to generate the AC power?
The financial section of the newspaper sometimes contains analyses that show an inflationary future (due to deficits and resource limitations), sometimes a stagnant economy, sometimes a thriving strength. Do you toss a coin?
Basically I want to make a realistic long-term decision on this.
