Price Is No Longer an Obstacle to Clean Power

(Bloomberg Opinion) -- As the harm from climate change becomes increasingly manifest, there is some good news: The estimated cost of reducing carbon emissions is falling rapidly. One dramatic example is an analysis by Geoffrey Heal of Columbia University showing that it would cost only $6...

"...Geoffrey Heal of Columbia University showing that it would cost only $6 billion a year for the U.S. to move to carbon-free electricity generation by 2050.
Even if the precise numbers are off, Heal is right to emphasize that the transition to cleaner energy is much less costly today than it used to be. Three forces are changing the math.
First, renewable power costs are dropping so fast, both utility-scale solar and onshore wind power have become cheaper than natural gas or coal power, as Lazard’s levelized-cost-of-energy estimates from 2019 show. As I wrote when these numbers came out, multiple forces have driven costs down, including ongoing improvements in technology and lower capital costs. (In November, Lazard will have updated estimates of the cost of various energy technologies.)
Second, the cost of storing renewable energy is also falling. The challenge with wind and solar energy is that they are intermittent, so they require either supplemental conventional power, such as combined-cycle natural gas, or enough storage to smooth the variation relative to demand. As storage becomes more affordable than supplementation, the share of energy production based solely on renewable power can expand.

Third, and crucially, many power plants are nearing the end of their useful lives and need to be replaced one way or another. That means the cost of building new facilities is a given, and shouldn’t be counted as a cost of the transition to lower-carbon electricity. ...
