If solar can’t pay for itself with “free” land and
the sunniest spot in America, where can it work?
Obama was way to close to my home yesterday, just 1.5 hours south in Vegas. Nominally there to tout energy policy, he was really there to raise money for Democrats.
He used Nellis AFB’s solar farm to tout “green energy” proclaiming it only cost $100 million to build and saves the Air Force $1 million a year!
Here we have Obama the lifetime politician NOT knowing, and likely not caring, how to conduct a real return on investment analysis.
First off, the land the government provided wasn’t in that cost. We could have sold the land or leased it to other activities. So the actual cost is $100 million + the opportunity cost for the land. Also, not factored in, was the cost of the Air Force personnel reviewing, managing and promoting the project. That had to be in the millions.
Second, money isn’t free. $100 million dollars costs around $2 million a year in interest costs.
So ACTUALLY this project costs $1 million a year and will never be paid for with savings.
But wait, it gets worse. It turns out the “savings” are financed in part by “renewable energy credits” sold to Nevada Power. This is a subsidy by government (state and Federal).
So the government is spending money with one hand, and claiming that money as a savings with the other.
Oh… and the savings are “estimated”, which means they are wrong.
In the end, even if the savings were real, a $100 million project with a 100 year payback is one of the worst investments you can make in energy technology. When will this project be obsolete? 20, 30, 40 years? Any reasonable estimate of obsolescence makes this a negative return project.
Wouldn’t it be nice we had a President who actually had run a business? Or lacking that, a media that had some clue as to how investment and returns work?

The naive chief donkey wouldn’t recognize an LCC estimate. R&D, sunk cost. $100M production cost. 25 year average to replace all major array subsystems damaged by hot-cold cycling and corrosion, $50M minimum. Keeping the panels clean in the Las Vegas wind blown dust bowl probably requires automated washing with expensive water, $1M/yr for 25 years times four. No cleaning, subtract 25% from efficiency. Salvage value, $4/lb. You could claim 100 years of operating cost, but why bother, solar’s only good for buildings.

I was being generous in my ROI estimate, and it was still lousy. Factor in equipment maintenance and depreciation and this thing is a financial turkey with deeply negative ROI.
