Creating and harnessing energy is a fundamental part of enabling
life to exist and thrive on earth. Energy comes in a vast array of
different forms - using our muscles and those of other creatures,
enabling us to move, lift etc, creating heat and steam through
fire, capturing the power of the wind in a ship's sails or to turn
the blades of a wind turbine, harnessing the power of moving water
to generate electricity in a hydroelectric power station, applying
the forces of magnetism to turn an electric motor, using solar
panels to transfer the sun's energy into electricity for our homes
- all of these and more are explained in 'Discovering Energy'.
