What happens when you switch a lightswitch? Or the power button on the TV? Electricity flows to the device and it switches on. Most of us use electrical gadgets all day, every day, without thinking about it. But where does electricity come from?

Solar power is one of the most exciting forms of renewable energy today. From the powerful solar rays to the bright light bulbs being switched on all over the world, we follow the journey from the source to the resource.

We look at other sources of energy, how the national grid works to move electricity across land and sea, and how it is fed into our homes. Home electricity is not the only use for solar power, so we look at solar farms, solar furnaces, solar towers and even solar transport. Finally we consider the future for solar energy and the advantages and disadvantages of this amazing resource.

Other titles in the Source to Resource series include:
From Field to Plate
From Oil Rig to Petrol Pump
From Raindrop to Tap
