Question 5

what is a renewable resource?

a resource that will not run out

Question 6

how is electricity generated from coal?

Answer 6

a fuel burns to heat water and produce steam. The steam drives a turbine, which is like a big fan. The turbine drives a generator. This provides the push that means a current flows in an electrical device in your home. For example: a kettle. The current transfers energy from the chemical store of the fuel to the thermal store of the water in the kettle.

Question 7

what are the advantages of using renewable and non-renewable energy?

Answer 7

using renewable energy does not produce much carbon dioxide when they produce a current or when they are built and are better for the environment. However, non-renewable resources are cheaper, easy to use and provide huge profits generated in the production of coal, oil and gas.

Question 8

what are the disadvantages of using renewable and non-renewable energy?

Answer 8

using renewable energy is more expensive, harder to install and isn’t entirely reliable or efficient. Non-renewable energy is bad for the environment as it produces carbon dioxide, a green house gas that traps heat in the Earth’s atmosphere, so it is a huge contributor to climate change.
