A set of practice questions and answers based on the Year 7 Energy Test transcript, covering energy types, renewability, and basic mechanics of power generation.

What type of energy uses sunlight to generate electricity?

Solar energy

What type of energy source uses moving air to turn turbines?

Wind energy

Which energy source uses moving water to turn turbines to generate electricity?

Hydroelectric energy

Which energy source involves burning fuels formed from ancient plants and animals over millions of years?

Fossil fuels (such as coal)

What energy type utilizes heat from inside the Earth?

Geothermal energy

Is coal considered a renewable or non-renewable energy source?

Non-renewable energy

Is solar energy classified as renewable or non-renewable?

Renewable energy

Is natural gas renewable or non-renewable?

Non-renewable energy

Is wind energy categorized as renewable or non-renewable?

Renewable energy

Is nuclear energy renewable or non-renewable?

Non-renewable energy

How does a wind turbine generate electricity according to the energy test?

Moving air is used to turn turbines which then generate electricity.

How is hydroelectric electricity generated?

It uses moving water to turn turbines.

Why is coal defined as a non-renewable energy source?

Because it is formed from ancient plants and animals over millions of years and cannot be replaced once used.

In a town with strong tides and lots of sunlight but no large rivers and little wind, which energy sources are most suitable?

Tidal and solar energy.

A town uses a mixture of solar, wind, and natural gas. Which of these are renewable?

Solar and wind are renewable; natural gas is non-renewable.

What is the primary factor that makes an energy source like wind or solar 'renewable'?

Renewable energy sources come from sources that will not run out, such as sunlight and moving air.
