What are the sources of energy we use?

Question 1

What do we use?

Answer 1

Fossil fuels
Solar energy
Hydroelectric energy
Wind energy
Geothermal energy
Biofuels
Nuclear energy

Question 2

What is solar energy?

Answer 2

Mainly comes from solar panels, capture sunlight and convert it to electrical energy
light energy ——> electrical energy

Question 3

What is hydroelectric energy?

Answer 3

Mainly produced by hydroelectric stations where electrical energy is created by turbines when moving water pours onto them
GPE—>KE—–>KE—->ELE
(dam) (water) (turbine) (generator)

Question 4

Wind energy

Answer 4

Mainly produced by wind turbines that convert energy from the wind into electrical energy

kinetic energy—-> kinetic energy—-> electrical energy

Question 5

Geothermal energy

Answer 5

Mainly produced by geothermal powerplants, electrical energy is produced from the earths core

heat energy–> kinetic energy —> kinetic energy —–> electrical energy

Question 6

Biofuels

Answer 6

made from animal waste or plant materials that cannot be eaten by humans
CPE —> heat energy —-> kinetic energy

Question 7

Nuclear energy

Answer 7

Energy harnessed from the nucleus of an atom

nuclear energy—>heat energy—->kinetic energy—> electrical energy
