Wind and Solar

• Wind power is generated by wind turbines which have blades that spin due to wind. This spinning action turns a generator which produces electricity.
• Wind turbines convert the kinetic energy from the wind into electrical energy.
• Solar power is generated by solar cells or solar panels which can generate electricity, directly from sunlight.
• The technical name for a solar cell is a photovoltaic cell.
