Energy: electricity generation units: MWe vs MWt

Self-tutoring about electricity and energy: the tutor mentions some units new to him.

At an electricity generation plant, MWt means “megawatts thermal.” It measures the energy input. MWe means “megawatts electrical.” It’s the output.

When burning fossil fuel such as coal to generate electricity, heat input is relevant. It’s not with wind or hydroelectric generation.
