Name two energy sources that you would consider to be renewable. Give reasons for your choices.
solution:
(1) Water energy (hydro-energy), water on Earth can be used again and again to generate hydro energy as it is stored again and again in dams due to the water cycle that exists in nature.
(2) Bio-mass energy, bio-mass can be managed by replacing the trees that have been cut down for fire-wood, cattle dung will be available as long as life exists on Earth. Thus, we can get a constant supply of energy at a practically usable rate.
