Stocks versus flows. You integrate power over time to get energy. 5% of the energy comes from coal but up to 50% of the power. That means that much of the time the use of coal power has to be less than 5%. Probably but not necessarily much less.
- linkregister 11y agoCan you elaborate? I can't remember that month of Physics when we learned how equations relating to power.

- Symmetry 11y agoPower is the rate at which energy is flowing. You can get the same amount of energy by either a large amount of power for a short time or a small amount of power for a short time. A way you could have up to 50% coal power but only 5% coal energy is if you use 0% coal for power 90% of the time but 10% of the time use 50% coal power.
