The UK’s first geothermal power plant was switched on this morning in Cornwall, providing a completely new type of renewable electricity for the country.

@kibcol1049 I'm struggling to see how the heat of the Earth's core is any more "renewable" than nuclear. It sounds more like 'heat death' to me. I blame Iceland. Or Sadi Carnot; definitely someone foreign.
@woo @kibcol1049 It's not renewable but it will last until the sun strips us of our atmosphere or completely consumes us.
It's not going to be anything we need to worry about because we're just not going to make enough difference to move that date forward.
It's solidly green as a power source but not every way of using it is.

Yep, if you screw up badly enough it's the GHG release from Hell, literally.

"Renewable" was always a stupid name for any kind of energy.
"Fossil fuel" was more accurate, but the Sun is also a fossil, really, and so are any radio isotopes.I think we should rather just stick to naming specific sources - oil, coal, wood, gas, are all really noxious and short-term energy sources.
Wind, hydro, and solar are far better
Nuclear is dicey, and is essentially playing a mean-spirited game of "surprise" with future generations who are going to discover waste -

@naturepunk @kibcol1049 I worry about anything that people believe to be free. I remember being told that the sea would be an inexhaustible supply of food once we started fish farming and it wasn't.

whomever naturally handles slightly irradiated homeless cannibals from beneath the Earth's crust, obviously. -

@woo @kibcol1049 The only warm part of the UK and they're sucking the heat out of it.

Don’t let “perfect” be the enemy of “good”. This is better than fossil fuels, so we should use it and get rid of them. It’s that simple.Plus once we get rid of gas for generating electricity, the price drops like a stone, because that’s the expensive bit.

"While primordial heat is slowly dissipating, the Earth’s interior is continuously replenished by another crucial source: radioactive decay. Certain naturally occurring radioactive isotopes, such as uranium-238, thorium-232, and potassium-40, are present within the Earth’s mantle and core. These isotopes undergo radioactive decay, releasing energy in the form of heat."
It's not just some finite heat source, but is being replenished in the main.

@davep @gareth @naturepunk @kibcol1049 That's still a finite energy source though the time-scales are much longer than I'd bothered to think about :-).

Sure, but again, getting rid of fossil fuels is the immediate goal.Let’s do that now, then worry about antimatter or zero point energy or some other exotic fuel afterwards.

@woo @davep @gareth @naturepunk @kibcol1049 buddy, the SUN is also a finite heat source. unless you have a perpetual motion machine, nothing is renewable on a cosmic timeline. the countdown to catastrophe for current fossil fuel use is maybe 50 years? fix this first and we have another billion years to worry about slightly cooling the earth's mantle

@davep @naturepunk @kibcol1049@gareth @davep @naturepunk @kibcol1049 But: we won't, just like we didn't worry about oil running out for 50 years or Climate Chaos.
