I do not think we can import the needed KW, what are they going to do?

i've been saying this for years. but everyone just calls me bonkers.

It's going to have to made up by people installing solar roofs and wind turbines. (At least in CA)

Enough panels to replace that amount of energy will have to cover most of the desert. I am sure the tree huggers will like that.

Someone did a study for Chicago and found that most of the surface of lake Michigan would be needed and that was not counting how to store the energy for night time.

Magic, apparently.

Nuclear could see a resurgence with a change in public perception. It is the cleanest and densest source of energy. Obviously, if the world could nail fusion then the sentiment to adopt nuclear would be instantaneous.

Until then, I don't think we will need to build a solar array the size of the whole desert.

States with strong sunlight and plenty of roofs obviously have the most potential—California, for example, could supply 74 percent of its total electricity use by covering its buildings with solar panels.

The amount of over produced power wasted at night could be utilized in vehicle storage.

My electric cooperative allows free charging at night up to 400Kwh per month for this very reason.

That only works until a lot of people have electric cars and typically uses non-renewable energy. Once everybody is charging their car at night it starts being high demand at night, when solar doesn't help and the wind is at its lowest speed on average.

Surplus of energy in the day can be stored in batteries, converted into hydrogen, used in place of hydro then hydro is released at night, and there are other storage solutions being considered.

Yep, not an insurmountable challenge, but costs time/effort/money. Also doesn't change the fact that mass adoption of EVs isn't as simple as "everyone just has to buy them because it makes sense right now". It requires significant infrastructure updates that many people do not seem to understand.

And then there are those days when PG&E just turns off the grid for fear of being sued (again) when the wind blows hard and causes the transmission lines to spark and start a wildfire. Smokey the Bear says "Only you can prevent forest fires. Sorry, no charging your EV today."

Imagine a world where you have to evacuate a wildfire area on foot because you didn't have power at your house to charge your vehicle.

Is this sarcasm? I can't tell and I don't want to assume wrong. But, if interviews with survivors of the Camp fires are to be believed, this is exactly what residents already had to do when the roads became impassable.


Uncharged electric or rolling petrol bomb, neither is a good choice.
