Morning Starters: Spring 1 - Clean Energy
Did You Know?
A tidal turbine is a human-made machine that is placed in the ocean to capture energy from the tide. The surge of water created during the rise and fall of tides causes the machine’s blades to rotate, which in turn produces electricity. Using tidal energy reduces greenhouse gas emissions, helping to combat climate change by providing a sustainable alternative to fossil fuels.

Critical Thinking
Despite being a clean and renewable energy source, there aren’t many tidal turbines in operation around the world.
What might be the reasons for this?
