What are greenhouse gases?

Back

Greenhouse gases are gases that trap heat in the atmosphere, contributing to the greenhouse effect and climate change.

Front

What is the role of turbines in energy production?

Back

Turbines convert kinetic energy from moving fluids (like water or air) into mechanical energy, which is then converted into electricity.
