Facts on Wind Energy

Fact 1

Solar energy is a completely free source of energy and it is found in abundance. Though the sun is 90 million miles from the earth, it takes less than 10 minutes for light to travel from that much of distance.

Fact 2

Solar energy which comprises of radiant heat and light from the sun can be harnessed with some modern technology like photo-voltaic, solar heating, artificial photosynthesis, solar architecture and solar thermal electricity.

Fact 3

The solar technology can be distinguished into active and passive. Photovoltaic panels and solar thermal collectors which harness solar energy are examples of active solar technology. Passive technology includes constructing rooms to improve air circulation, orienting space to favorably use sunlight.

Fact 4

Passive technology includes constructing rooms to improve air circulation, orienting space to favorably use sunlight.

Fact 5

The water cycle is an important result of solar insulation. The earth, oceans and atmosphere absorb solar radiation and their temperature rises. Warm air rises from the oceans causing convection. When this air rises to high altitudes, clouds are created by condensation of water vapor. These clouds cause rains that bring water back to the earth’s surface which completes the water cycle.
