Quote:a voluntary crippling of our economy
See, that;s interesting right there. The reading I've done about it and the politicians I've heard that make sense, all say that a gradual but purposeful shift toward clean energy industries would
help,not hurt the economy.
Especially in the long term.
I agree fully with that goal. Until a couple of years ago our electrical power has for many decades come 51% from Coal, about 40% from nuclear plants and 9% from renewable sources 2/3rds of which ( 6% of total came from hydroelectric power and 3% from wind & solar).In the last 5 years we have seen a massive shift from coal to natural gas, resulting from improved directional drilling techniques and fracking , which has reduced the coal fraction to about 25% and yielded a GHG reduction about five times what has been achieved thru in several decades of heavy subsidies for wind and solar power. Moreover the natural gas transition delivered power at less than the economic cost of coal, partly compensating for the subsidies on renewables, and lowering the cost of a commodity that everyone, rich and poor, uses.
We are fast approaching the block obsolescence of our ~ 95 nuclear plants which today deliver emission free power at about the same low cost as natural gas. With what will we replace them? Oddly environmentalists and AGW advocates generally vehemently oppose nuclear power, notwithstanding it's far safer record than all the other major sources, and the zero emission that result from it's use. . Doubling our natural gas output doesn't look likely, and wind & solar are very expensive and yield only ~25% of the power per unit generating capacity installed, compared to other sources ( wind and sun are limited sources).
At current cost rates replacing nuclear power with wind and solar would raise the real cost of electricity by about 60% on average, and this ignores the additional cost of replacing the base load generating or storage capacity needed to serve a 24/7 grid in a world in which the sun doesn't shine and the wind doesn't blow all the time.
What would you do? This may be a good point at which to begin a reasoned practical discussion of alternatives.
