As the article says the price of solar is coming down. If we want people to get off carbon energy, then we need something even better. The solution is not with mandates, it is not with subsidies, it is not fuel cells for a "tiny" movement house. If you want people off carbon fuels, then give them something better. I personally have checked into solar shingles, fuel cells, windmills for the home. So far not one of them is a smart decision to invest in. If we want to have this work here is what has to happen:
1) It has to be cheaper than what we have today( and this means no subsidies as well)
2) Every bit as reliable as the grid today.
3) Can not have any impact on my life of home style. Not interested in joining the "tiny" house movement in other words.
4) ROI must be very short time, like 2 years.
5) Does not require any governmental involvement.
What is going to save the environment in the long haul is a better mouse trap, not all the other crap that is being proposed.
Really? 2 year ROI?
That's not even remotely close to the cost structure or ROI for new coal or natural gas power plants...
You have 'subsidized' the energy model you use now for many decades; you 'pay' for the new coal or natural gas plant, or new high-voltage transmission lines thru line item costs on your bill, where someone ELSE pays out the major investment, pays the interest on the loan, and then charges you for those additional costs every month, practically forever (most of those are 20 yr to 30 yr ROI; they utilize 30 year or 40 year loans which are completely invisible to you).
Are you claiming that you wouldn't buy an LED bulb that was a 60 or 100W equivalent, because it costs 20x more than a standard incandescent, but the ROI is 3 years or 5 years? And once that ROI is met, you have continued cost savings for another 15-20 years??!!!
FWIW, rooftop solar may require a 10-15 yr ROI, but based upon reasonable assumptions for energy cost increases vs time and a 30 year lifetime for the panels (which most are warranted for), investment in solar can equate to a 4% to 5% year-over-year return for the 30 years. That's not bad, considering once you put the panels up, there's practically no risk to the ROI and cash flow.
The main issue with wind and solar is energy storage; you get power when the wind blows or sun shines, not on demand. Once energy storage costs drop enough to compete with standard 'central grid' technology, we will see a major shift in energy use and distribution, with localities setting up their own 'storage' areas and only pulling from the grid during extreme events/high usage.
