(I) Electrification displaces energy demand. Efficiency controls growth of demand. Various limits have been reached with efficiency.
(II) Demand response is not about “do not use power because we don’t have enough.”, it is about “here is some money so you shift demand to a later point in time when saturation is lower.”
(III) It doesn’t take years to find better ways to manage the grid as is. Do you think there won’t be a need to upgrade large portions of the grid to handle new nuclear plants?
THE UK gets 30% of its electricity from wind and another 5% from solar; Denmark gets 70% from renewables, mostly wind. Iowa gets 65% of its electricity from renewables, mostly wind; California, whose economy is larger than that of most countries, gets 38%, mainly from solar.
But some lobbyists are trying to kill momentum, especially those who see nuclear as a silver bullet. It is not.
- Moldoteck 1y agoElectrification doesn't displace demand. It adds more demand. what you described with demand response is equivalent of rationing- use power when weather is good because otherwise you'll not afford it Don't confuse transmission needed for 1GW of nuclear vs 10GW of solar with 10% cf and more redispatching requirements

When someone buys an EV rather than ICE, do you think the EV uses the same amount of energy than the ICE car? > what you described with demand response is equivalent of rationing- use power when weather is good because otherwise you'll not afford it Sure, what do you think that needs to be done when there is a limited resource such as electricity? Yes, more production, but until then, what should the grid do if the demand is growing? > Don't confuse transmission needed for 1GW of nuclear vs 10GW of solar with 10% cf and more redispatching requirements It is two different models, one is centralized (nuclear) and the other is distributed (solar). The planning is essentially different.
- Moldoteck 1y agoIce didn't use electricity. It used energy from fossil fuels. Are you comfusing things? Electrification does add electric demand. It reduces total energy consumption due to efficiency but electric demand still grows Yes, you need vastly more transmission for a distributed ren grid. Both for deployment and for avoiding curtailment
- zekrioca 1y agoIt is very hard to argue when you think electricity != energy, and you cannot even see that EV displaces the use of fossil fuels (I.e., a type of primary energy), even when you yourself wrote that it consumes less energy lol Solar panels in rooftops can decrease the saturation of the grid, so more transmission is not necessarily needed.
