What harmful substance is released when burning coal and oil?
Sulfur dioxide, which causes acid rain, harmful to trees, soils, and ecosystems.
What environmental problem is caused by burning fossil fuels?
They release carbon dioxide (CO₂) into the atmosphere, contributing to the greenhouse effect and global warming.
How can acid rain be reduced?
By taking sulfur out before the fuel is burned or by cleaning up the emissions.
What makes fossil fuels and nuclear energy reliable?
There’s enough fossil and nuclear fuels to meet current demand, and they can be extracted from the Earth quickly enough so power plants always have fuel in stock.
Why is nuclear power considered dangerous?
While nuclear power is clean, the nuclear waste is very dangerous and difficult to dispose of.
How does coal mining affect the environment?
It can spoil views and make a mess of the landscape, especially open-cast mining.
Although costly to set up, why are fossil fuel power plants widely used?
The running costs aren’t that expensive and they offer a cost-effective way to produce energy.
What environmental issues are caused by oil spills?
They cause serious environmental problems, affecting mammals and birds that live in and around the sea.
What are non-renewable resources?
Resources that cannot be replenished in a short period of time, such as fossil fuels and nuclear energy.
Why did electricity use in the UK increase over the 20th century?
Due to population growth and increasing use of electricity for more and more things.
What is a cost factor for nuclear power?
The overall cost is high due to the expense of the power plant and final decommissioning.
How has electricity use in the UK changed since the beginning of the 21st century?
It has been decreasing slowly as we get better at making appliances more efficient and become more careful with energy use in homes.
What is a risk associated with nuclear power?
It always carries the risk of a major catastrophe like the Fukushima disaster in Japan.
What happens if no new resources of fossil fuels are found?
Fossil fuel stocks may run out within a hundred years.
Apart from generating electricity, what else is oil used for?
Oil (diesel and petrol) is used for fuel cars, and gas is used to heat homes and cook food.
What fuels are used for generating electricity?
Fossil fuels and nuclear power.
