Wind turbines and hydroelectric power (dams and rivers) can harm or destroy wildlife's natural habitat.
When will oil run out?
Some people forecast that the world will run out of oil by 2030 and other fossil fuels after 2050
issues with solar and wind power
.
Although solar and wind power are more environmentally friendly, they are impractical. The UK is not very sunny and wind turbines do nothing if it isn't very windy and have to be switched off if it is too windy!
