1. Energy and Power Energy (E) is measured in joules (J)
Energy cannot be destroyed, only change form!
Energy is converted through work (e.g. chemical energy to kinetic energy)
Power (P) is measured in watts (W) and gives the amount of energy converted per second: 𝑃= 𝐸 𝑡
Electrical energy is very useful, so we use many different sources to make electricity

2. Renewable
Non-renewable
Makes electricity
via heat
Makes electricity directly
