How does the use of hydroelectric energy compare to the use of coal?
a. hydroelectric energy is more commonly used than coal.
b. hydroelectric energy is associated with less waste production than coal.
c. hydroelectric energy has a larger environmental impact than coal use.
d. hydroelectric energy requires more land space than coal use

B. Hydroelectric energy is associated with less waste production than coal.

Hydroelectric energy makes use of water from the natural environment, and thus the water can be replenished from the natural water cycle and it is unlike coal that is associated with production of waste such as CO2.

So Hydroelectric energy produces less waste compared to coal.
