Coal power stations create airborne radiation; you can point at nuclear waste. And while peole talk about "half a million years", after 10,000 years gamma radiation equals that of the original ore & overall radiation is 10,000X less. Over a lifetime, but much less than half a million years. 2/13 - ThreadSky

10 000 years.
Sounds reasonable.
LOL

There's hidden deaths from coal power, even with nuclear accidents, you kill 3,000X more people for the same power. Chernobyl was the Soviet Union, Windscale was a weapons ( not power ) reactor, Three Mile Island had in fact a minimal release, and Fukushima resulted from inept regulation. 3/13

Fukushima, well I there I worry about our human frailties, and our ability to properly regulate things, because the fault really rests with our human "original sin" rather than nuclear technology in itself. Still, you kill fewer people overall with nuclear. 4/13

But human frailties are fixed now?

At the other end of the scale, I recall an administrator of a nuclear power station, that he signed 500 bits of paper a day. Yes, nuclear obliges a regulatory framework with good scrutiny, but driven by unrealistic fears, that's not necessarily what we'll get. 5/13

Non sequitur

OK, coal fired power stations, what about renewables? I'm happy for household solar cells, but it is a private initiative. While you can pull less power from the grid, it harder to feed more of that power back. And houses take up 30% of our energy consumption, you can only do so much. 6/13

Four million households have solar panels. That's quite a private initiative.
It's also more electricity generation than the entire coalition "plan"

Yes, let's try to make power users more flexible - aluminium extraction electrolytic cells with better "idle" states - but limiting the power use in hospitals and other places is a bit silly - you can only go so far. 7/13

Nobody has proposed that

Cranking out distributed solar & wind with a matching 24 hour grid is a gargantuan task, like a space or atomic bomb program. Mines soak up all the tradies in local towns - think about this on a capital city wide scale. Ramping up will be challenging, in terms of the diversions in the economy. 8/13
