"Renewable energy effectively utilizes natural resources which are naturally replenished."


ISSUE DATE:


22.11.2007


From Left to Right and Top to Bottom
you can see (some descriptions for the kids):

1. 'SOLAR ENERGY' Solar energy can be converted into other forms of energy. The major drawbacks of are: the intermittent and variable manner in which it arrives at the earth's surface and, the large area required to collect it at a useful rate.

2. 'WIND ENERGY' Wind energy is mainly used to generate electricity. Wind is called a renewable energy source because the wind will blow as long as the sun shines :)

3. 'SMALL HYDRO POWER' Hydro energy is electricity made using water.

4. 'BIOMASS ENERGY' There are a wide variety of biomass energy resources, including tree and grass crops and forestry, agricultural, and urban wastes. It is the oldest source of renewable energy known to humans, used since our ancestors learned the secret of fire. And what a great 1st day cancellation showing the sun... very nicely done! Without the sun no other energy could exist!!!
