All energy exists in finite amounts. There is a finite amount of solar energy that hits the planet.

Back to the original issue, electricity does not travel well beyond a certain distance. Even at the very high voltages, it has significant losses. Distributed generation is best.

Battery storage technology STILL isn't great. It weighs too much. It takes too long to charge. And some of the new technologies are prone to catch fire.

Tesla came out with the "Power Wall". It came in 2 flavors, 7kWh for $3000 and 10kWh for $3500. You had to put down a deposit to get in line for a Powerwall.

Details were skant. Now, the 10kWh is cancelled. The 7 kWh is really 6.4 kWh. And it still doesn't come with any of the equipment needed to make it work.

Tesla generated $250-300M in working capital in these deposits. They are marketing geniuses. But the actual products always seem to fall short.
