What's worse for the environment Keith, coal or lithium?
Coal. By a mile. Lithium can be recycled, and the infrastructure for doing this will increase just like it did for lead car batteries. Once electric vehicles really take off, there will be a huge amount of investment in new battery technology. It may not be lithium that gets used.
Fossil fuels poison the air once used, which lithium does not.

Coal cannot be a large scale energy source if we wish to avoid climate change. Nuclear, hydro, batteries and renewables.

It is now a fact that solar power is less expensive to produce than coal power, yet our government has still given a green light to Adani for his coal mine, & they are planning to build yet another coal power station!!! This is Big government & Corporatism at work, total corruption at our expense.
Keith.
Correct. The amount of wind and solar projects either under construction or planned exceeds the coal production capacity. What this means is that within about 5-10 years we are going to see coal fall to less than 50% of generation. This will remove the argument that those who don't understand climate change usually use to push against electric vehicles.

I'd rather gradual global warming, that we can prepare and adapt for, than a sudden nuclear apocalypse caused by nuclear power stations.

Disasters in Russia, America and Japan have shown we can't be trusted with nuclear energy.

Nuclear isn't a viable alternative to coal because of the massive risk.

Vastly more people are killed by coal each year during mining and from the pollution, than from uranium. That said, nuclear power still isn't as good as renewables. A major trend now is to turn the giant scars that coal mining left into pumped hydro systems powered by renewables. When there's wind & sun, they pump up, when there isn't, they generate into the grid. With this, the size of our grid and the surge in battery installations, the usual garbage "what about when the wind isn't blowing..." doesn't cut it any more. Coal power stations are already closing down faster than they are being built. This trend is unlikely to change.

Good to hear, but don't we still have a problem with nuclear waste, & of course the ever present threat that someting could go wrong with the power station & contaminate the area?

Yes. Australia is the best place in the world to store it, but in 1000 years time, what happens to people who stumble upon it? We have plenty of space for wind, heaps of sunshine and plenty of spots for pumped hydro. There is no reason that the main grid could not go 100% renewable within 20 years.
