Can you name 3 energy sources used in power stations to heat water?
Fossil fuels, uranium, plutonium, and biofuels.
1 of 12
What are the disadvantages of using overhead powercables?
They do not look asthetically pleasing. birds and aircrafts can sometimes fly into them.
2 of 12
Can you name 5 ways which we generate electricity renewably?
Solar pannels, wind turbines, hydroelectric dams, wave turbines and tidal.
3 of 12
What is geothermal energy?
in a volcanic area steam is prduced, the trapped and used to turn a turbine.
4 of 12
Can you name two ways which people manage to match supply wit hdemmand?
they either increase supply, or decrease demmand.
5 of 12
What is an advantage of using a wind turbine over using solar pannels?
a wind turbine produces a lot more electricity.
6 of 12
What is pumped storage?
hydroelectric energy, which is then stored in a dam as gravitational potential energy, when demmand increases the dam is opened and the water turns a propellar to generate electricity.
7 of 12
Can you name 4 factors which affect the type of energy source used in a certain area?
noise and visual pollution, destruction of wildlife habitats, production of waste materials and release of substances into the atmosphere e,g CO2.
8 of 12
What are people doing to reduce the ammount of CO2 being released into the atmosphere?
they are catching and storing it in natural oil and gas fields such as those under the North Sea.
9 of 12
What is an advantage of using a tidal turbine over a power station?
There are no nasty gases or polution caused. it is renewable.
10 of 12
What source of energy has the shortest start up time?
gas fired station.
11 of 12
What source of energy has the start up time?
nuclear power station.
