Excellent informative post and explained very well.

I've tried explaining this to people before but you have expressed it so well I'm cutting and pasting that into my collection of "here's one I prepared earlier" answers!

Have you much insight into T-class (tripath) amps. I've heard that T-amps produce the least distortion of all popular amplifier designs, are cheap to make and cheap to drive. Any wisdom here?

Labour get redistributed.

Has any technology ever had any long term unemployment increasing effect throughout human history? I've heard and read about the fears of human unemployment crisis due to X tech, but I'm yet to see any hard evidence of it in the real world.

If machines are doing ALL the jobs, then other than for social/psychological reasons I can't see why unemployment is an issue, we'll have food thanks to "robots".

Did the article say wilderness is being lost to habitation?

I'd assume a significant proportion of wilderness loss is for agriculture, mining, clearing (for resources, wood, etc) .

I'm not sure habitation has much to do with it at all. Fill a city with another 2M people and you're going to need to clear wilderness to farm food for said people.

Surely that's a stawman argument.

"Reducing use of fossil fuels" != "halting all progress"

You use the phrase "slow this progress" but the remainder of your comment implies almost halting progress.

Limiting use of fossil fuels has (relatively short in terms of human history) economic consequences which will be overcome. If we drastically reduced the use of fossil fuels today I doubt it will take hundreds of years to find a working cleaner alternative, especially when there is economic motive.

I'm certainly talking about market spot prices.

So far there has been sufficient supply (note, they DID/DO purchase the power at the stated prices) It's just not generated locally by our own market, so when we fall short on local supply we need to purchase from our non local suppliers who can and do set their spot price.

So the facts to back up my contention is that at no point was there not enough supply to meed demand. It's only the cost of the supply that's the point of contention.

IF they are forced (due to supply constraints and not economic constraints) to start doing rolling blackouts or similar due to inability to meet demand then I'll stand corrected. But having worked directly with our largest whole-sale provider to implement demand management systems at the customer end (experimental) I can be rather confident that the supply is there if they are willing to pay the price.

In past years our local suppliers would do rolling blackouts during high demand periods to avoid paying for costly supply. This typically occurred during summer. This has been offset by using roor-top-solar. But still, it's always been about price, not availability.
