evacuated. All in all, I think that hydroelectric dams should be the world’s main source of power. This is because the world biggest problem involves the pollution. Rather than burning fossil fuels and use nuclear power, we could stop some major problems. This source is better than solar or wind energy because it is easier to depend on. Water exists in both day and night and everyday. With geothermal energy, you must be near a geyser, and this isn’t as abundant as water. In conclusion, the world should rely on hydroelectric energy more than anything else....
