Efficiency = (useful energy output/useful energy input) x 100
Mankind needs to find an alternative to fossil fuels because they will run out.
Nuclear Fusion
- Combine two light hydrogen atoms
- This makes heavier ones, and during the process there is the realease of energy
- It is clean
Nuclear Fission
- A proton in directed at Uranium 235
- It splits its nucleus, and heat energy is given out
- It is not clean, and an uncontrolled reaction
Other types of energy sources:
- Solar Energy: harnessing the nuclear fusion power of the sun
- Wind Power: Wind used to dirve turbines that turns kinetic energy into electrical energy
- Hydrogen and Fuel Cells: Hydrogen can used as a fuel, with only water as the combustion product.
- Tidal Wave Energy: This is using the difference in elevation between high and low tides to create energy through a turbine.
- Biomass: The burning of vegetation and plant matter to generate energy from heat.
- Ocean Thermal: Capturing the heat in the sea
- Hydro Electric Power: Flow of built up water to run turbines.
