It is also the most important of the non-conventional sources of energy because it is non-polluting and, therefore, helps in lessening the greenhouse effect. Solar energy can also be used to meet our electricity requirements. The Earth receives 174 petawatts (PW) of incoming solar radiation at the upper atmosphere.Approximately 30% is reflected back to space while the rest is absorbed by clouds, oceans and land masses. The spectrum of solar light at the Earth's surface is mostly spread across the visible and near-infrared ranges with a small part in the near-ultraviolet.

Methods 2 save energy

Energy-Saving Lighting : Use energy-saving lighting - Save as much as 65% on lighting costs. Replace older incandescent bulbs with energy-efficient fluorescent lights. Switch to less expensive fuel: Use the least expensive fuel - Why pay electricity prices when you can run your heating and water heating equipment with less expensive oil or propane? We'll help you with the switch. Water Heating: Cut water-heating costs - Save about half the energy you use for water heating. Install a heat recovery system. It uses the heat from the compressor to pre-heat water.
