re the often-repeated claim that renewables are dropping in price and increasing in efficiency:

I wonder, would the Globe publish a letter where I claimed that one plus one is rapidly becoming three and by mid-century it will be four?

That is essentially what renewable energy enthusiasts claim. 

Around five p.m. at this time of year, the sun goes down. Solar power production, already in decline since noon, stops altogether.

And yet, artificial lights all over Ontario -- and elsewhere in most human settlements across the northern hemisphere -- go on.

That phenomenon is a result of engineering. Not solar power, and usually not wind power. And not magic.

The renewables enthusiasts think that the machines that keep Ontario's lights on -- world-class machines that were invented in Ontario, by Ontarians -- are yesterday's machines.

I say, who cares when they were built. They work today. Solar doesn't.

I don't want renewables enthusiasts anywhere near my power system.
