Energy resources and there features

Question 1

/Is nuclear energy renewable?
How does it work

Answer 1

No
It releases the energy stored in the nucleus. The typical fuels used are plutonium and uranium

Question 2

2 advantages of nuclear fuel
2 disadvatages of nuclear fuel

Answer 2

adv- produces loads of energy and reliable
disadv- radioactive waste and it takes up a lot of money to store it properly

Question 3

How do biofuels work

Answer 3

they release chemical potential energy stored in living things by burning them

Question 4

2adv for biofuels
2disadv

Answer 4

-doesn’t need any special equipment and doesn’t add to greenhouse effect.
disadv- large areas of land are needed to grow trees

Question 5

What are wind turbines used for

Answer 5

to turn the kinetic energy from the wind into electrical energy

Question 6

advantages of wind and disadvantages

Answer 6

adv- no pollution, nothing gets burned and turbines are cheap and easy to use
dis- they can be ugly/noisy and if the wind level is low you don’t get as much energy

Question 7

how does hydroelectricity work

Answer 7

flowing water has kinetic energy. hydroelectric dams convert this energy into electricity

Question 8

advantages and disadvantages for hydroelectricity

Answer 8

adv- no pollution
-can store the water up high
disadv- costs a lot of money to build a dam
-the dam can ruin the local environment

Question 9

how does geothermal energy work

Answer 9

it can use the heat from the centre of the earth to boil water to make steam. This is used to create electricity or radioactive rocks

Question 10

geothermal advantages and disadvantages

Answer 10

adv- no pollution
-no damage to the environment
disadv- very few places in the world where you can do this
-costs a lot to do this

Question 11

how does tidal work

Answer 11

the tide works by when the water goes up it gains gravitational potential energy. This can be turned into electrical energy

Question 12

tidal advantages and disadvantages

Answer 12

adv- no pollution
- cheap to run
disadv- costs a lot to build a dam
-the dam can cause local flooding

Question 13

how does solar energy work

Answer 13

this uses the heat and light from the sun to create energy or water for homes

Question 14

adv and disadv for solar

Answer 14

adv- no pollution
-free fuel
disadv- solar cells aren’t reliable (only works well if sunny)
-doesn’t work at night

Question 15

water waves work

Answer 15

fast moving waves have kinetic energy which can be converted into electricity

Question 16

advantages and disadvantages for water wave

Answer 16

adv- no pollution
-renewable
disadv- needs a lot of machines
