Alternative Energy

Question 1

Hydroelectrical Energy

Answer 1

Generated by harnessing the energy of flowing water. The water goes through a generating station and spins a turbine to create electricity.

Question 2

Fossil Fuels

Answer 2

Produced from the organic matter of organisms that lived millions of years ago. They are non-renewable. They are burned to create power.

Question 3

Biomass

Answer 3

A renewable resource. Made up of plant and animal waste. The waste decomposes and turns into methane which can then be burned to produce power.

Question 4

Nuclear Energy

Answer 4

Atoms of a heavy element split during “nuclear fission”. This releases TONS of heat energy. This is used to heat water and create steam to turn a turbine. Sometimes renewable.

Question 5

Geothermal Energy

Answer 5

Water is heated by molten rock in the earths core. It then rises to the surface as hot water and steam. Hot enough to heat homes/buildings.

Question 6

Solar Energy

Answer 6

Sunlight is captured in solar panels. This energy is then used to heat homes and buildings, and power calculators, watering systems, etc.

Question 7

Wind Energy

Answer 7

Wind turbines use the energy of moving air, to spin their blades which are connected to a generator. Faster wind = more power.

Question 8

Tidal Energy

Answer 8

Harnesses the energy of the tides to generate electrical energy. The rising and falling tides make turbines spin in a generator which then produce energy.
