22
Q

Coal

A

Compressed carbon from plants

23
Q

Oil

A

Compressed carbon from animals

24
Q

How is the energy from fossil fuels released

A

They are burned/ need to combust

25
Q

Steps of creating energy

A

1.Coal is burned to turn water into steam
2.Steam goes into a turbine and spins it around
3.The turbine spins a generator that produces energy by moving electrons through a wire

26
Q

Renewables

A

Wind, hydroelectric, solar & biomass

27
Q

How wind energy works

A

Wind turns the blades that turn a generator to produce electricity

28
Q

How hydro works

A

Water in dams is directed in vales to turbines that spin generators to produce energy

29
Q

How solar works

A

panels use photovoltaic cells to harness energy

30
Q

How biomass works

A

plant or animal material is burned for energy, and the heat turns a turbine & generator for electricity
