I had wanted to dig into the costs of a Florida solar facility that Obama recently visited. Fortunately Ronald Bailey does it for us:
Now let's do a rough calculation of the costs of DeSoto Solar versus conventional power sources. According to the Electric Power Research Insitute, a modern 1,000 megawatt coal plant without carbon capture technology would cost about $2.8 billion to build. Adding carbon capture would boost the cost to as much as $4.7 billion.
The 25 megawatt DeSoto facility cost $150 million. Scaling it up to 1,000 megawatts would cost $6 billion. But coal power plants operate 90 percent of the time snd solar only 30 percent, so in order to get the equivalent amount of electricity out of solar plant would mean tripling the capital cost for a total of about $18 billion. In other words, building a solar power plant costs between 4- and 6-times more than conventional, or even carbon capture, power. Even worse, a scaled up DeSoto-style plant costs 18-times more than a natural gas plant.
