The section on how much solar can power homes is off. The deployed capacity is measured by the output of the panels in direct sunlight on a cloudless day. Obviously, that doesn’t happen all the time, or even most of the time. Exact measurement depends on local conditions, but if you take the figure and reduce it by 80%, you’ll have a rough idea of how much is actually going on the grid over time.

So when he’s citing how many homes can be serviced by 1GW of solar, multiply that figure by 0.2 and you’ll get something closer to the real one.

Solar and wind deployments, combined with some kind of energy storage, are important, but we shouldn’t drop wildly misleading figures. If the numbers in the video were right, then we’d have solved the problem of carbon-based electricity generation already.
