Renewable and Non-Renewable Energy

This lesson takes a deeper look at renewable energy resources — how they work, their advantages and disadvantages, and how they compare to non-renewable resources. This is part of the AQA GCSE Physics specification (Section 4.1) and is frequently examined.

Renewable Energy Resources

Renewable energy resources are naturally replenished and will not run out on a human timescale. They generally produce little or no carbon dioxide during operation, making them better for the environment.

Wind Energy

Wind turbines convert the kinetic energy of the wind into electrical energy. The wind turns large blades, which spin a generator inside the turbine.
