Toyota CEO ( a very popular company around these parts now-a-days) Agrees With Elon Musk: We Don't Have Enough Electricity to Electrify All the Cars: https://pjmedia.com/news-and-politics/bryan-preston/2020/12/21/toyota-ceo-agrees-with-elon-musk-we-dont-have-enough-electricity-to-electrify-all-the-cars-n1222999
That's the inconvenient truth that no one talks about. OR wanted to talk about. Infrastructure.
Some of the Tesla fans around the world are discounting him for saying that cause Toyota doesn't currently makes EVs. While also saying there IS enough electricity at night.
I can understand if you are using hydro power then there is no excess capacity at night. If you are using coal and nuclear power then there IS excess capacity at night. Also fewer megawatts going into oil refineries unless you are just adding BEV to the automotive fleet with no reduction in ICE vehicles.
So long as these vehicles are charging at night and have capacity for their days usage, then it is pretty much all good. If you would need to supplement the overnight charge with additional daytime charging, you might not be the audience for an electric car.
I really just see the BEV as a means of extending the lifespan of the ICE vehicle by taking a slice out of the demand for oil. Keeps petroleum affordable to the masses just a little bit longer.
The equation is not that simple.
Depending on where in the world one is, the primary supply of power could be hydro, coal, gas, wind, solar, nuclear, etc.
Off those choices, gas and coal would be the easiest to dial up or down the power output. Nuclear is pretty much fixed. Hydro power is also easy to modulate, they just need to bring extra turbine(s) online or off line. With a reservoir behind the dam, the water pressure and volume is more or less constant no matter how many turbines are online when couple with a spillway, more turbines running means less water going around onto the spillway, less wasted energy. Solar and wind will always depend on nature.
Right now there is still only a tiny fraction of EVs on the road when compared to normal cars. The market is still growing, and the current spare capacity from power plants can still support the extra load. But how long can that excess capacity last? Global car sales is projected to top 62 million cars for 2020. USA alone should be around 15 million. Say those 15 million will all be EVs. Each car will take ~9kW per hour on overnight charging at night at home. That's 135,000,000 kW, or 135 gigawatt of power per hour that goes on for hours at night. A typical nuclear plant only supply 1 gigawatt. Do we have 135 gigawatt of spare electricity output right now? Say all those cars aren't charged everynight, say maybe every 3 nights so each night only 1/3 of the load is needed, that's still more than 40 gigawatt of power.
Residential transformers, like those that hang off a pole, are like 25-50kWs, and they supply 4-7 houses each. Which means if there are more than say a couple EVs charging there is going to be a risk of blowing that transformer. So those will need to be ungraded.
Those hanging transformers are also served by big box giant transformers somewhere in the neighbourhood, increasing the size of the hanging ones means bigger ones for these also. The lines might also need upgrading to support higher current. Residential areas aren't designed to be a high drain locations in the first place.
Now for places that uses coal or oil plants, yes your car isn't burning hydrocarbons, but is it really gone? No, it got shifted to the power plant where it needs to burn extra hydrocarbon to meet the demand. And those powerplants don't have catalytic converters to clean the exhaust. It's just a not-in-my-backayrd thing. The problem of not using hydrocarbons hasn't been solved.
Even Elon sees this problem, and he has already asking for better infrastructure as he needs to sell more EVs. Infrastructure is lacking behind badly. Those improvements also don't come overnight, Most will need 5-10-20 years of advance planning, environmental studies, power source studies, etc. One don't start building out only when you hit the limit, one start planning for the future when it looks like the limit might be hit.
