Sunlight

Sunlight is the most important resource in life. All our energy is ultimately derived from sunlight. Right from the burning of coal, oil and other fossil fuels to even hydroelectric power generation! Infact, it is precisely because the heat of the sun causes evaporation of water that water can be transported from a lower level to a higher level. And when this water moves back down, we can use this potential energy to power generators which generate electricity. We must learn to revere the sun for what it actually is, that is the source of all physical life on earth.
