What are the advantages and disadvantages of non conventional sources of energy?

Answer 1

Advantages of conventional (non-renewable) energyThe advantage of conventional energy is it's easy and cheap to use. There is no better way to store transfer and use energy than gasoline for powering motor vehicles. It's quick to pump fossil fuel into a car. It's stable in the tank and the gas tank holds quite a bit, and a gasoline powered car is cheap to manufacture.

• Coal is a ready-made fuel.
• It is relatively cheap to mine and to convert into energy.
• Coal supplies will last longer than oil or gas
• Oil is a ready-made fuel.
• Relatively cheap to mine and to convert into energy
• It is a relatively cheap form of energy.
• It's a slightly cleaner fuel than coal and oil.
• Gas is a ready-made fuel.
• Nuclear has a small amount of radioactive material produces a lot of energy. And raw materials are relatively cheap and can last quite a long time.
• It doesn't give off atmospheric pollutants.
• Biomass is a cheap and readily available source of energy. and If the crops are replaced, biomass can be a long-term, sustainable energy source.
• Wood is a cheap and readily available source of energy.

If the trees are replaced, wood burning can be a long-term, sustainable energy source.

Disadvantages of conventional (non-renewable) energyNon-renewable energy comes from fossil fuels (coal, oil, natural gas, uranium):

• they are non-renewable and fast depleting;
• they emit carbon dioxide when burnt, adding to the greenhouse gases in the atmosphere and pushing us faster towards global warming;
• they leave behind harmful by-products upon combustion, thereby causing a lot of pollution;
• mining of such fuels leads to irreversible damage to the adjoining environment;
• Fossil fuels pollute the environment
• They will eventually run out.
• Prices for fossil fuels are rising, especially if the real cost of their carbon is included.

Answer 2

Advantages:

1. Available free of cost

2. Cause no or very little pollution

3. environment-friendly

4. inexhaustible

5.have low gestation period

6. do not deplete Natural Resources

7. can sustain energy supply for many generations.

Disadvantages:

1. available in dilute form in nature

2. cost of harnessing energy is very high

3. availability is uncertain

4. difficulty in transporting such resources
