The table below shows the use of some energy production methods over time. Type of energy Average energy used annually in the past (in million tons) Average energy used annually at present (in million tons) Average energy most likely to be used annually in the future (in million tons)
Oil 200 4000 300
Gas 100 2500 700
Coal 1000 2500 1400
Wind 0.1 50 2000
Hydropower 0.7 60 150
Tidal power 0.02 50 500

Based on the table, which of these statements best describes the potential impact of different methods of energy production on the environment in the future?

The height of tides may increase.
The speed of winds may decrease.
Greenhouse gases in the atmosphere may increase.
Population of wading birds in coastal locations may decrease.
