RESOURCES Energy is defined as ‘the capacity to do work’. Sun is the primary source of energy. Joule is the standard unit of energy in SI units. Energy utilization is an index of economic development‚ which does not take into account of ill effects/damage on to environment. From 1900 to 2000 population increased by 3 times while energy consumption by 14 times! Energy Resources All energy sources ultimately come from the sun‚ the moon or the earth.
