How do coal-fired power stations work?

What is electricity essentially described as in the text?

• The movement of electrons through a material

• A type of energy that can only be generated by solar panels

• A form of light

• A chemical reaction

Which of the following is NOT listed as a main source of electricity?

• Coal-fired power stations

• Nuclear power stations

• Gas-fired power stations

• Biomass energy

What is the system of wires that carries electricity to our homes and industries called?

• The Grid

• The Circuit System

• The Power Network

• The Electric Web

How is electricity produced in the simple generator described?

• By turning coils of wire surrounded by magnets

• By heating water

• By solar panels

• By burning coal

What has been the number one source of electricity in the world over the past 100 years?

• Coal-fired power stations

• Solar panels

• Hydroelectric power stations

• Wind farms

What is the first step in generating electricity in coal-fired power stations?

• The coal is set on fire

• The water boils and turns to steam

• The steam spins turbines

• The coal is dug up

What do the turbines in coal-fired power stations resemble?

• Boilers

• Solar panels

• Windmills

• Generators

What happens to the steam after it has spun the turbines in a coal-fired power station?

• It is cooled down in the condenser

• It is reused without treatment

• It is stored for future use

• It is released into the atmosphere

Why are coal-fired power stations often built near coal mines?

• To minimize water usage

• To reduce transportation costs

• Because of legal requirements

• To use the natural landscape for cooling

How do gas-fired power stations differ from coal-fired power stations in generating electricity?

• They burn natural gas instead of coal

• They do not use turbines

• They use a completely different technology

• They generate electricity without burning any fuel
