Shower of born idiots. We'd be stuck with smelly tallow candles if your great great granparents had their way. Gas light - fifty years of carbon monoxide. Incandescent light - eighty years of profligacy- more heat than light by several hundred percent. Better than open gas flames perhaps. Compact fluorescent - of course they're made in China, you won't buy anything that's 20p more expensive than the cheapest in the cheapest store, so responsible manufacturers go bust. LED - well, at least they don't contain a few milligrams of mercury, but that isn't your fault is it?

Let's start again. Society went wrong when Newcomen discovered how to make power from fossil fuels. Backtrack to there, and tell us how it should be done.

Newcomen?? Who's he. I hear you ask.

Born idiots.
