fossil fuels adv and disadv

Answer 13

Question 14

nuclear adv and disadv

Answer 14

Question 15

how do wind turbines work

Answer 15

Question 16

how do tidal barrage systems work

Answer 16

remember sluice gates open when tide is high, close until it is low, then open again - this is repeated

Question 19

wind power adv and disadv

Answer 19

Question 20

water power adv and disadv

Answer 20

Question 21

solar power adv and disadv

Answer 21

Question 22

solar panels vs solar cells

Answer 22

Solar Panels
The panels are fitted on a roof. Infrared radiation from the Sun shines through the glass lid and heats the water in the pipes.

Solar cells
A solar cell is a circuit component that uses light from the Sun to generate electricity. Many calculators use solar cells, and many houses have panels on their roof. Space probes often use solar cells to generate the electricity they need.

Question 23

how does nuclear power work

Answer 23

fuel = uranium (/plutonium)
uranium fuel is in sealed cans in the core of the reactor
the nucleus of a uranium atom is unstable and can be split in two - energy is transferred from nucleus when this happens
there are lots of uranium atoms in the core so it becomes very hot

the energy of the core is transferred by a fluid (the coolant) that is pumped through the core:
coolant’s very hot when leaving core - flows thru pipe to a heat exchanger, then back to reactor core
energy transferred is used to turn water into steam in the heat exchanger, this drives turbines that turn electricity generators

Question 24

how are fossil fuels and biomass used

Answer 24

Question 25

pump storage

Answer 25

Question 26

why is national grid important

Answer 26

designed to be able to adjust its supply to fluctuating energy demands
