Example:
Solar energy ==> stored in chemical form in a tree as the tree grows
Chemical energy in the wood ==> released during burning
Heat from the burning wood ==> absorbed by water,
makes the water boil
Steam holds great energy as heat,
steam pressure is used to turn a steam turbine
Kinetic energy of the turbine turns an electric generator
Electrical energy from the generator flows through
cables to your house, is available at outlets
You plug your battery charger into an outlet,
electrical energy flows through the charger
into the rechargeable batteries, where it is
stored until you want to use it.
