Governments are addressing this problem by allowing developers to build energy-inefficient housing developments over some of the best farmland in the country.
EVs are simpler and cheaper to build than ICEs, but weāll need to see near 100% sales for a decade or more to drastically shift the needle here. It has been done, Norway is up around 85% EV use now.
Currently EV sales are suppressed by fear of not having a charger, or simple lack of education around the running cost advantages of owning an EV. As people realise that cost of living is less with an EV, that will drive take up.
The big issue over the medium term is the energy demand for charging. We currently need more EVs to soak up the excess solar thatās being generated, but thatās good for 1 million cars. Beyond that we will need to add dedicated transmission and generation to feed into car batteries. The energy grid will be seriously strained with the intense demand, so upgrades will be needed.
Iām not a fan of the complaints about environmental impact of EVs as they are largely similar to the impact of making ICEs. As industry converts to green energy, the embodied carbon in EVs will drop. We need the cars to drive scale in that industry, in order for the green economy to scale up. We canāt wait for the coal to be retired before starting to build the fleet of cars, as weād lose a decade of production.
So renewable electricity combined with EVs for private use gets us about 70% of the way there. Then we are looking at shipping, trucking, agriculture and heavy industry.
Ammonia made from solar will probably become the transport fuel. Hydrogen is likely going to do the industrial heating demand that has currently does. And there will be more inventions over the coming decade.
How are we going to replace all these EVs, solar panels etc. without burning fossils? Solar panels last like what, 12 years? Hundres of millions of them will need to be replaced fairly regularly. We need to replace 4 billion cars with electric ones? How are we going to do this without fossil fuels? Genuine question.
I dont really see them being taken up here (outside metro areas) at large scale until their retails drop further, people donāt get range/charger anxiety and we stop doing dumb ā ā ā ā like trying to slap an unconstitutional tax on EVs just to cover the fuel excise that ICEs cop
Solar panels have a 25-30 year lifespan. I suspect that many will last longer, just at poorer performance.
By that point we should be 100% renewable, so energy use to make more panels would be green. We should also have a decent panel recycling industry by that point, so the energy required to make them should be reduced.
I read that thatās one of the biggest challenges for moving semi-trailers over to EVs. Some companies in US that have wanted to move their small 8-10 truck fleet to EVs in country towns have approached the local government for support in providing power sub-stations, only to be told that the power requirement for their small fleet is greater than the current supply for the entire town, and would simply not be possible.
I see many issues for hitting climate targets, not the least of which are the continued move of billions of people in poorer countries from very basic living, to becoming consumers, which will continue to require access to more power, currently being supplied mainly by fossil fuels.
But Iām also not a fatalist, and I believe we will continue to innovate to provide solutions to a very real problem that needs solving. I also wonder what options we have/will have for scrubbing carbon from the atmosphere if/when we fail to meet required targets, that might buy us more time to transition to renewables.
I have also seen several reports and papers saying that renewable power options simply wonāt have the power density required to move away from fossil fuels, and that nuclear power plants are the only real option to meet demands in the timeframe required. And I note that Musk and Gates are pro-advanced nuclear plants. Advanced nuclear power plants could produce 1% the waste of legacy plants, and produce waste that decays to background levels in 400 years, rather than tens of thousands of years. The proponents of nuclear also point to the fact that even the worst disasters produced by legacy nuclear disasters have in reality resulted in very little loss of life or continued problems in survivors, and accidents like Chernobyl canāt happen in modern/advanced nuclear power plants.
