Dams Can give negative effects to the environment
it not that efficient
they use it for 1.transportation 2.recreation 3.hydroelectric energy
Worst to best way to generate electricity: 1.)Nuclear Energy 2.)Fossil Fuels 3.)Solar Energy 4.)Wind Energy 5.)Hydroelectric 6.)Geothermal Energy
moving..<3.
Our major energy source in the UK is fossil fuels (coal oil and natural gas) which constitutes 2/3rds of our energy production Nuclear and renewable energy such as wind, hydroelectric and solar make up the remaining 1/3.
1. biogas 2. wind 3. solar 4. nuclear 5. hydroelectric 6.biomass 7. Geothermal 8. wood
There are 3 and they are hydroelectric wind and solar.
World energy consumption is about 5 terawatts of oil, 4 terawatts of coal, 3 terawatts of natural gas, 1 terawatt of nuclear power and half a terawatt of hydroelectric power. That is about 13.5 terawatts combined.
the sun is the main source of energy for earth but indirectly as by solar energy the plants do photosynthesis which powers the planet earth . you may find detailed info in the book "eating the sun by oliver morton"
