Renewable Resources - The resources that can be replenished by the environment are called the renewable resources. These are also called the inexhaustible resources. These resources are constantly recycled in the environment like water. This also includes resources like the sola..

Resources which are in limited amounts and cannot be renewed are called non-renewable energy resources. Fossil fuels like coal and petroleum are some examples. Petroleum products are energy-rich components of carbon which have undergone anaerobic degradation..

I.Renewable: They can be replenished or reproduced easily. They are continually replaced at a faster rate than we use them up. Examples include solar energy, water power and biomass II.Non-renewable: They have a limited supply and can not be restored after use. ..

Water hyacinth, (weeds that clog major waterways) restricting boat traffic are held in check in a lagoon by careful harvesting. Biogas plants use these dried plants as raw materials. Capturing this energy storehouse from woods, crops, algae, animal and human wastes, or sewage cr..

Nuclear Energy - Nuclear energy is the energy released when certain changes take place in the nucleus of an atom. Nuclear energy is partly renewable and partly non-renewable source of energy. Nuclear fission and nuclear fusion ar..

Non-renewable or conventional energy resources. Most of the energy, which people are using, is derived directly or indirectly from the sun. Non-renewable energy resources are those, which have been in use since a long time. Availability of petrole..

Renewable sources of energy are produced continuously in nature and are non-depletable. Sources like water, sunlight, air, tidal energy, nuclear energy, geothermal power, are not exhaustible. A non-renewable source of energy gets depleted..
