Alternatives To Fossil Fuels

Question 1

What are renewables?

Answer 1

Infinite energy source e.g. solar, biomass, wind

Question 2

What are recyclables?

Answer 2

Will eventually run out but not as fast as fossil fuels e.g. nuclear

Question 3

Solar

Answer 3

Advantages- No emissions, currently serving 73% homes in some areas of UK

Disadvantages- Consumes productive farmland that may be better producing food instead, expensive so only accessible for developed countries

Question 4

Wind

Answer 4

Advantages- Provides power for around 1 million UK homes, Hornsea Project 1 create 2000 jobs

Question 5

Biomass

Answer 5

Advantages- Cars running on biofuel emit 80% less CO2 than petrol cars

Disadvantages- Causes deforestation e.g. in Brazil, combats reducing emissions and reinforces rural inequalities (TNCs inflate land price and take away farmland)

Question 6

Nuclear

Answer 6

Advantages- No emissions

Disadvantage- More expensive than most renewables, still requires large amounts of initial energy for turbine, can be unsafe e.g. Fukishima disaster

USA responsible for 30% global nuclear energy
