The Answer to Climate Change Is Renewable Energy, Not Nuclear Power

39. Judging by that off point answer you don't seem to know what primary energy is

I repeat the main point you ignored - in the past decade renewables have increasingly become less expensive than the fossil fuel alternatives.

The secondary point, about primary energy, looks to have confused you. Primary energy is the total energy embodied in a fuel; of which, usually only a minor percentage is delivered to the end user for work. A good rule of thumb is that 70%+ of the energy in the coal on your graph isn't helpful to the end user.

That has significant implications on the quantity of renewables (like wind and solar that produce electricity directly) required to replace or substitute for coal.
