Which sources of energy are non-renewable?

The fossil fuels, meaning coal, oil and natural gas, and nuclear power, which depends on a finite supply of uranium.

How does a wind turbine produce electricity, and where are turbines sited?

Moving air turns the blades, which drive a generator; they are placed on exposed hills, coasts or offshore where the wind is strongest and steadiest.

Give one advantage and one drawback of wind power.

It releases no greenhouse gases once the turbine is built, but it generates nothing when the wind drops and many people object to turbines spoiling a view.

How is hydroelectric power generated?

Water stored behind a dam is released through turbines built into the dam wall, and the force of the falling water spins them to drive generators.

1
What is the difference between a renewable and a non-renewable energy source?
Model answer
A renewable source is replaced naturally as fast as it is used and will not run out; a non-renewable source exists in a fixed quantity and is eventually used up.
2
Name the renewable sources of energy.
Model answer
Solar, wind, hydro, tidal, wave and geothermal power, together with biomass.
3
Which sources of energy are non-renewable?
Model answer
The fossil fuels, meaning coal, oil and natural gas, and nuclear power, which depends on a finite supply of uranium.
4
How does a wind turbine produce electricity, and where are turbines sited?
Model answer
Moving air turns the blades, which drive a generator; they are placed on exposed hills, coasts or offshore where the wind is strongest and steadiest.
