Question 1

What are the types of Energy

Answer 1

Renewable,
Non-Renewable,
Recyclable

Question 2

What is Renewable Energy?

Answer 2

Replenished in short timescale

Known as flow resources

Question 3

Different types of Renewable Energy?

Answer 3

Wind - turbines on land and see - large wind farms

Solar - sun energy heats water and solar cookers -> electricity via photovoltaic cells

HEP - falling water trapped by dam - falls through tunnels - pressure creates electricity

Question 4

What is Non-Renewable Energy?

Answer 4

Can’t be replenished quickly

Known as stock resources

Question 5

Type of Non-Renewable Energy?

Answer 5

Fossil Fuels - formed over millions of yrs - dead organisms in ground and seabed - extraction is difficult and costly

Question 6

What is Recyclable Energy?

Answer 6

Made of waste products to generate energy

Question 7

Types of Recyclable Energy?

Answer 7

Nuclear - Uranium atoms - give off heat when split - boils water - steam turns turbines to create electricity - Breeder reactors can generate more fuel from splitting process - makes it like a renewable source - Radioactive waste used to generate more energy

Biomass - wood, plants etc or animal waste - burn to release energy or to create biofuels. Easy - living organisms grow quickly. Available from farming waste
