What Does That Mean?

Let's look at manageable units of production, such as a PV manufacturing facility that produces 5MW of solar panels per year.

How many terajoules does a 5MW array produce?

It's about 10,000MWhrs - or 36 terajoules.

Global use is 580 million terajoules.

This says replacing all energy requires about 20 million times this amount.

Welcome - to 20 million solar entrepreneurs. That is 2.5 people out of 1000 people on earth. The would be doable, so let's do it.
