Energy, power, and energy resources

When people talk about "making electricity", they usually mean transferring energy into an electrical pathway so it can be used. Energy is measured in joules (J), while power is the rate of energy transfer and is measured in watts (W), where 1 W=1 J/s1\,\text{W} = 1\,\text{J/s}1W=1J/s.
