Seven percent of what? Overall, averaged out? The issue is balancing currently sunny and currently windy places with those that are currently calm and currently dark.
Is it possible to build enough renewable energy to power the entire world? How much wire does it take to transmit enough electricity for North America over 3,000 miles to Europe and Asia (and back). How much wire to transmit from North America to South America and from Europe and Asia to South America? Is it possible to build a power wall for every home, business, government office, house of worship, and charity in the world?
What good are solar and power walls in the Arctic and Antarctic? Solar would be fine in the summer, days are long, but can power walls last throughout the winter? Can they generate enough electricity in the summer to store for the winter? Four million people live in the Arctic Circle.
If we manage to power the world with renewables and power walls, how will we replace them in twenty or thirty years?

Cars are energy agnostic.It doesn't matter where the power comes from.
Since EVs basically embody the best-case-scenario as far as CO2 is involved,we'd be foolish not to think hard about them.Seems.
Raise the price of gas to $15/gallon,or charge oil companies for the ARMY,NAVY,MARINE CORPS,AIRFORCE,CIA,NSA,NRO,etc.,and see how that reflects prices at the pump,then stand back and watch what people do in the marketplace.
Remember,Adam Smith talked of a free market.He wasn't for democracy.He wasn't a republican.He'd seen first hand the abuses of The British East India Company.He said that the only reason a rich man could sleep peacefully at night,was because he had a strong government watching his back.And his best friend was an atheist.
Fossil cars will become like Typhoid Mary some day.

Australia has less than 10% of the population of the US and uses maybe 5% of the electrical power. So I'm only maybe 5% impressed a grid backup worked.
Fossil fuel powered cars are still going to be dominating new car sales through at least 2040. A large portion may be plug in hybrid but they will still be able to burn liquid fuel.

7% of generated capacity from a power plant is lost to resistance in the power lines of the grid.
Im' goin' from memory,but I believe that it was Harrison in the 1980s who claimed that the Atacama desert of Chile,received enough solar radiation such that at 10% conversion efficiency,the entire planet could be powered from this single source.
A global grid is just a bricks and mortar sort of thing.If it's important,it will happen.No resource constraints.For what we'll lose from not doing the 2025 CAFE standards we'll be losing 1,800,000,000,000/year in the US alone.You could probably pay for some cable with that.
We replace things now.How do we do it? Is there some structural mechanism in the marketplace which will fail us in the future?
I don't believe that Antarctica is inhabited,other than research teams.
Some indigenous populations in the Arctic Circle live entirely off reindeer.They don't use electricity at all.The Chukchi come to mind.Other peoples will be leaving,as their way of life is vanishing and wasn't important enough to Barbie and Ken,that they'd be willing to do anything for them while there was still time to act.There just people of color you know? Who cares?

Abraham Lincoln,when interviewing Ulysses S.Grant,asked Grant how many Union soldiers it would cost to prevail at a particular battle.When Grant told Lincoln the number of tens of thousands killed that it would take,Lincoln expressed gratitude,that he'd finally met a general who understood arithmetic.
Perhaps,somewhere,in the world,there are people today who understand the arithmetic of electrical power and grid backup who's analysis would resonate with you.
Perhaps your prediction will play out.I've seen others.
I'm reluctant to slam people who are trying.
Fossil people won't go down without a fight.Who'd blame them.
Without a war declaration it will be hard to distinguish true patriots from slackers.

I'm saying fossil fuel generation should go away, save the coal for making steel.
Replace fossil fuel with nuclear power. There is something like a 300 to 500 year supply of uranium and at least a 1000 year supply of thorium. By the time those run out nuclear fusion should be figured out.

Everything we are capable of now is the direct result of vast energy availability from fossil fuel. It is so energy dense, transportable, storable, and cheap, it is nearly indistinguishable from magic. 1 gallon of gas or diesel has 35kWh of thermal energy. For 5 bucks.
.
.
.
.
570 Liters of diesel per day = 5,700 kWh per day. Even if you cut that by2.5 for the extra efficiency of electric motors with round trip losses you get 2,300 kWh per day for a large size farm machine. 12 Tesla grid scale 200kWh powerpacks per day to hot swap in and out. for just one tractor. We are going to need to start making a lot of wire to get all of this power around.

Show me his math. Of how we can transmit all of the nightime load from solar panels in China, across the bearing straight, to Chile and Eastern USA.

Dance, monkey-boy, dance? You can start with the articles he published in Fortune magazine in Feb 1940. I don't have a source.

Once again I argue we need people planting mangrove forests, coconut palms, and other plants that turn sunlight and saltwater into oxygen.
I use that stuff!
