Well we can keep on mining Coal and pumping Oil, then start harvesting methane clathrates from the sea bed, constantly in ever growing volume.
Or.
"The irony of the green revolution is that we - at least for the medium to short term - need a supply of new metals mined out of the ground," says Prof Richard Herrington, head of earth sciences at London’s Natural History Museum.
We can extract the minerals we need, build them into batteries, recycle 98% of the materials when they hit their life expectancy and when we finally hit the volume of batteries we need, the materials become self sustaining through recycling.
I know which one of the two I'd prefer.
As for heat pumps? Heat pumps do one thing and do it fairly well, but within bounds. They reduce the amount of electricity required to heat or cool your home by 200% to 500%, depending on the spec of the pump and the climate conditions at the time and also whether it is connected to a ground source or just air based.
The goal of a heat pump is to allow the electricity infrastructure to support the transition from CO2 burning gas and oil to non CO2 burning grid electricity.
Forget all the marketing, hype or BS. That is what it is about.
The longer we deride these moves, the harder the climate impact will be. There is, quite literally, no sum of money we can spend larger than the impact of uncontrolled climate change. None. It is in multipliers of the value of the total world economy, each and every year, ongoing.
We just need to get on board. The decision for 2030 curtailing of pure FF engines has already driven Nissan to commit to both a battery factory and EV vehicle production expansion in the UK. This is GOOD for the UK and for the climate overall.
It is all very well picking holes in all of this. But, without offering a viable alternative; trying to shout down activity which is guaranteed to meet our goals is not constructive.
What people need to get on board with is that whilst reducing our emissions and cleaning up our energy infrastructure will cost a lot of money, the cost of not doing it is astronomically higher. Not just in money but also in lives.
