WIND ENERGY

Wind is air particles in motion. Since the rotation of the Earth allows the poles to stay cold while the Sun heats the equator, air molecules continually move between these areas with different temperatures.

TIDAL ENERGY

The tides are the source of tidal energy. The tides are continually in motion because the positions of the Moon and Sun relative to the Earth continue to change. Gravity makes the water move from high levels to low levels.

ELECTRICAL ENERGY

Electrical energy (electricity) can be supplied to our appliances when electrically charged particles are moving through the wire. The electric current does not exist unless electrons are moving.
