Interesting calculations.
When you’re talking about this many trillions, you’re talking serious money! Figure at least $50 trillion for the whole deal. Another consideration is the longevity of the equipment. Solar panels begin to degrade after 20 years or so. Inverters, required to convert direct current coming from solar panels into alternating current, rarely last 20 years. Batteries as well have useful lives that rarely exceed 20 years. If America “goes solar,” Americans need to understand that the entire infrastructure would need to be replaced every 20 years. Not only is this spectacularly expensive, but it brings up the question of recycling and reuse, which are additional questions that solar proponents haven’t fully answered. A solar array large enough to produce nearly 10,000 gigawatts in full sun would occupy about 50,000 square miles. Imagine tearing out that much hardware every two decades. Reprocessing every 20 years a quantity of batteries capable of storing nearly 40,000 gigawatt-hours constitutes an equally unimaginable challenge. To the extent the United States does not go 100 percent solar, wind is an option. But the costs, infrastructure challenges, space requirements, and reprocessing demands associated with wind power are even more daunting than they are with solar. Americans, for all their wealth, would have an extremely difficult time moving to a wind and solar economy. For people living in colder climates, even in developed nations, it would be an even more daunting task. For people living in still developing nations, it is an unthinkable, cruel option. The path forward for renewable energy is for utilities to purchase power, from all operators, that is guaranteed 24 hours-a-day, 365 days a year. This is the easiest way to create a level competitive environment. Purveyors of solar power would have to factor into their bids the cost to store energy, or acquire energy from other sources, and their prices would have to include those additional costs. It is extremely misleading to suggest that the lifetime “levelized cost” is only based on how much the solar farm costs. Add the overnight storage costs. Take into account costs to maintain constant deliveries despite interseasonal variations. Account for that. And then compete.
