It can be harnessed from the Earth's natural heat associated with active volcanoes or geologically young inactive volcanoes still giving off heat at depth.

• Biomass Energy

• Geothermal Energy

• Solar Energy

• Coal Energy

It can be heated, burned, fermented, or treated chemically to release energy.

• Biomass Energy

• Geothermal Energy

• Solar Energy

• Coal Energy

It provided by the sun is the most inexhaustible and cleanest source of energy known. Its heat and light arrive week in and week out - free.

A Scottish physicist and one of the great theoreticians of all times, mathematically unified the electric and magnetic forces. He also proposed that light was electromagnetic radiation.and South poles.

• William Gilbert

• Pierre de Maricourt

• Michael Faraday

• James Clerk Maxwell

He discovered an electric current flowing through a wire can cause a compass needle to deflect, showing that magnetism and electricity were related.
