No source of energy can be pollution-free. It is considered that solar cells are pollution-free. However, even their making causes environmental damage indirectly. Also, in the case of nuclear energy, there is no waste produced after the fusion reactions. However, it is not totally pollution-free. TRead more
No source of energy can be pollution-free. It is considered that solar cells are pollution-free. However, even their making causes environmental damage indirectly. Also, in the case of nuclear energy, there is no waste produced after the fusion reactions. However, it is not totally pollution-free. To start the fusion reactions, approximately 107 K temperature is required, which is provided by fission reactions. The wastes released from fission reactions are very hazardous. Hence, no source of energy is pollution-free.
The advantages of nuclear energy are as follows: • Large amount of energy is produced per unit mass. • It does not produce smoke. It is a clean energy. • Fission of one atom of uranium produces 10 million times the energy released by burning of one atom of carbon. • Fusion of four hydrogen atoms proRead more

• Large amount of energy is produced per unit mass.
• It does not produce smoke. It is a clean energy.
• Fission of one atom of uranium produces 10 million times the energy released by burning of one atom of carbon.
• Fusion of four hydrogen atoms produces huge amount of energy.
Geothermal energy is the heat energy present inside earth in certain regions called hot spots. Due to geological changes, molten rocks formed in the deeper hot regions of earth’s crust are pushed upwards and are trapped in hot spots. When underground water comes in contact with the hot spot, steam iRead more
Geothermal energy is the heat energy present inside earth in certain regions called hot spots. Due to geological changes, molten rocks formed in the deeper hot regions of earth’s crust are pushed upwards and are trapped in hot spots. When underground water comes in contact with the hot spot, steam is generated. This steam is routed through a pipe to a turbine and used to generate electricity.
Energy from the oceans can be obtained in the form of tidal energy, wave energy and ocean thermal energy. But these energy sources suffer from the following limitations: • There are very few locations where dams to utilise tidal energy can be built. • Cost of installation of power houses is extremelRead more
Energy from the oceans can be obtained in the form of tidal energy, wave energy and ocean thermal energy. But these energy sources suffer from the following limitations:
• There are very few locations where dams to utilise tidal energy can be built.
• Cost of installation of power houses is extremely high and efficiency of plants is comparatively small.
• Power plants built in oceans or at sea-shores will need high continuous maintenance as chances of corrosion are extremely high.
Hydrogen has been used as a rocket fuel. Would you consider it a cleaner fuel than CNG? Why or why not?
