Q

Nuclear usage
Pros and Cons

A

Nuclear fuels are reacted to heat water to produce steam to turn turbines to generate electricity
Produces no greenhouse gases or pollution
Small amount of fuel produces lots of energy
Produces dangerous radioactive waste that can take thousands of years to decay
Non-renewable

Q

Bio-fuels usage
Pros and Cons

A

Plant matter, ethanol or methane can be produced and used as a fuel in place of fossil fuels
CO2 produced while burning the fuel is balanced by the CO2 absorbed whilst producing it
Can take up lots of land and consume resources needed for food production

Q

Wind usage
Pros and Cons

A

Wind turns turbines directly to generate electricity
Produces no greenhouses gases or pollution
Land can still be used for farming/offshore wind farms
Not reliable(not always windy), turbines can be noisy and ugly

Q

Hydroelectric usage
Pros and Cons

A

Water is stored at a height, and when released, rushing water turns turbines directly to generate electricity
Reliable and can produce large amount of energy quickly
Produces no greenhouse gases or pollution
Can involve flooding large areas, destroying important wildlife habitats
Renewable

Q

Geothermal usage
Pros and Cons

A

Hot rocks underground are used to heat water to produce steam to turn turbines to generate electricity
Reliable, geothermal stations are usually small
Can result in release of harmful gases from underground
Not many places are suitable

Q

Solar usage
Pros and Cons

A

Solar cells use light to generate electricity, solar panels use thermal radiation to heat water to produce warm water for household use
Produces no greenhouse gases or pollution
Good for producing energy in remote places
Not reliable (requires sun), solar farms use up lots of farmland
Renewable
