Energy is the power or potential ability to do work. Good energy supply is vital for a growing economy. Energy can be found in many forms. Some forms are usable and easy to create goods and services from.

Plants by the process of photosynthesis catch solar energy. At the outer edge of the Earth's atmosphere incoming radiation is approximately equal to 1370 W per square metre at 90 degrees to Earth's surface. There is however, diffuse solar radiation coming in at other angles. As the incoming radiation enters the marvelous heat engine we call the atmosphere it is heavily transformed, particularly by the water vapour, a major greenhouse gas.
