True or False: Burning coal in electric power plants is a major source of CO2 and other emissions. However, its use doesn't have negative consequences beyond the emissions caused by combustion.
-
Sorry, that’s incorrect.
Mining coal disturbs the land and modifies the chemistry of rainwater runoff, which in turn affects stream and river water quality.

On average, how much solar radiation reaches each square meter of earth?
-
Sorry, that’s incorrect.
On average, even after passing through hundreds of kilometers of air on a clear day, solar radiation reaches Earth with enough energy in a single square meter to run a mid-size desktop computer-if all the sunlight could be captured and converted to electricity.
-
Correct!

If electricity production wastes between 40 and 65% of the primary energy source, why is it used?
- Producing electricity is a way to store energy.
- Electricity production results in no harmful emissions.
- Electricity is a versatile energy carrier.
-
Sorry, that’s incorrect.
Most direct uses of primary energy are limited to generating heat and motion. Electricity, by contrast, is extremely versatile, with a wide range of complex applications.
