Our house actually has a renewable energy surplus, including driving because we charge our EV from our own solar panels.

Yes, but that’s peanuts in comparison, like maybe 10% of the total cost of having the panels installed.

Annoying that the picture in the thumbnail shows as a video, but it cannot be played. Instead it plays another video?

I like the concept, if you can install it yourself it’s a huge saving compared to having a company do it, for us installation of our solar panels by an independent company was €4.600,- which is a pretty steep price IMO, and a significant part of the whole investment of getting solar panels.
But demand is simply so high that they can almost charge what they want. And despite the high price there was over a month waiting time.

Interesting. 👍😎
I live in Denmark in the are with the best farmland in the country. We are also the most southern part of Denmark, so also the best for solar panels.
Despite the fertile land and very high prices on farm land, we are among the areas in Denmark with the most solar panels.
I don’t know if your numbers are accurate, but I know the gist of it is.

We absolutely need to move everything to electric, because electric is more efficient, both for creating mechanical power like in engines, and for heating, and obviously for lighting.
It twice as efficient for mechanical power, meaning that even if you sue the gas an engine would have used, to make electricity instead, and then run the same task on an electric engine, the electric engine saves power compared to the gas engine.
I heating heat-pumps generate 4-5x the heat of the electricity they use. Even when losing 50% of the power turning fossil fuel heat into electricity, you come out with at least twice the utilization with a heat-pump.
Light is of course obvious, even with old incandescent bulbs electricity is about 5-10 times more efficient at creating light, with LED the factor is about a 100x.
Fossil fuels are obsolete, and bio fuels are too. Electricity is the future, and when created from renewable sources, I estimate the difference to be at least 20x advantage to electric over fuel.

he electrify generated by solar panels on it would allow EVs to cover 70x as much distance

Yes I absolutely believe that can be the case, and even if it is a best case scenario, there can be no doubt about which is the right thing to do.
Unfortunately we have 3 months per year where we can’t make much solar power, where we can have days with zero output.
But even under these conditions, solar has helped us here in Denmark to cover 80% of our electricity from renewable sources. With the goal of achieving 100% by 2030. We in our household have almost zero electricity bill 9 months of the year, and the surplus from the good months almost pay for the remaining 3 months. With an electric car, we can charge when electricity is cheapest.
For 2 of my neighbors that drive far for work, the cost is almost exactly a tenth driving an EV over buying gas.

This is not surprising, USA is one of the countries in the world that has the best conditions for solar. Also without using any significant amount of fertile farmland.
Still this number is very low, since there are other considerations, like easy access for maintenance.
The picture shown is just about the absolute ecological ideal, with good bio diversity that facilitates wild life.
