2 A new ‘green’ school is being built. Solar panels Triple-glazed windows Rainwater harvesting Recycling bins Wind turbine How do these features help it to be environmentally friendly?

3 cork Forms of energy coal thermal (heat) chemical potential sound kinetic (movement) gravitational potential electric

4 Energy-transfer diagrams Sun Solar panel Power lines Transferred as light energy Transferred as electrical energy

5 Energy-transfer diagrams Battery (store of chemical energy) Mobile phone Surroundings Transferred as electrical energy Transferred as light energy Transferred as sound energy The mobile phone also transfers energy as heat energy. This is not useful. It is wasted.
