- RENEWABLE ENERGY
- BIOMASS
- How it works. Burning biomass releases chemical energy. It can be converted into gass
- Advs. It is cheap and available. Friendly alternate to fossil fuels. Crops absorb CO2.
- Potential. Appropriate for LEDC's. Global use has increased 40%. But depends on land availability.
- Disadvs. Deforestation can occur. Only renewable if crops are replanted. Biomass waste can be a hazard.
- WIND
- Advs. Renwable. Takes up less space. Appropriate.
- How it works. Wind turns blade. Rotational energy becomes electrical energy.
- Disadvs. Unreliable. Produces little energy. Noisy.
- Potential. UK - strong winds. Could prove 20% by 2030.
- WAVE
- Adv. Renewable. No damage to land.Widely available.
- How it works. Harnessed by a wave generator that contains a turbine.
- Disadv. Not reliable. Expensive.
- Potential. Department of Energy and Climate change - 20% UK's electrical needs.
- TIDAL
- Advs. Reliable.Renewable. No emissions.
- How it works. Turbines underwater across tidal zones.
- Disadvs. Expensive. Environmental damage to ecosystems.Can be damaged.
- Potential. More predictable that wind and solar. Developing.
- SOLAR
- Advs. No pollution. Cost effective. Long lasting.
- Potential. Sun hitting 1 mile equivalent to 4 million barrels of oil.
- How it works. PV cell converts light into electrical currents.
- Disadvs. Expensive. Do not work at night or when cloudy
