(continued from previous post)
So you suggested using the numbers that result from a simple search, and I find this report with numbers for Jan-Mar 2016:
http://www.ferc.gov/legal/staff-reports/2016/mar-infrastructure.pdf
From the table labelled "New Generation In-Service (New Build and Expansion)" and calculating the percentage, I find that 87% of new installations are renewables. Great, that is quite close to 100%. However comparing the number to "total available capacity", I find that it is only 0.68% improvement per year. This means based on this rate, it would take about 30 years to achieve an improvement of about 20%.
And looking at other reports suggests that there were already numerous subsidies and 'clean energy programs' in play to achieve these numbers. The same report shows that "total available capacity" of existing natural gas installations is about 43% in the US. Since current use in generation is only 33%, this means that NG generation can be increased further without requiring new installations. Considering that a new installation not only needs to provide a slightly cheaper rate, but also justify the up-front investment for a new build, subsidies of this kind would have a hard time accelerating this rate (or even double it, as you seem to suggest), and as far as I can tell in this thread, you haven't provided any numbers showing otherwise.
Compare this to the mandates set by the states which we currently discuss the most, California and Nevada:
California mandates 33% renewables by 2020, and 50% by 2030. (
California Renewable Energy Overview and Programs)
Nevada mandates 25% by 2025.
So based on the info I've seen from you, and the fact that you only refer me to google in response to my above questions, I have to conclude that the effect of subsidies for utilities of the kind which you argue for, would fall far short of programs already in place in California and Nevada, at least.
