Mainly electricity generated in India is from – 

 Hydro power plant 

 Thermal power plant 

 Nuclear power plant 


To construct new Hydro power plant following are problem :-

1. There is limitation to select the site of HPP because of their site selection criteria. 2. The building of large dams can cause serious geological damage. 3. Due to construction of dam and creating large reservoir, this can force the relocation of large numbers of riverside cities, towns, villages & people. 

To construct new Thermal power plant following are problem :-

1. It produces air pollution. 2. It has lowest overall efficiency (29-47 %). 3. It is more, as quantity of fuel required is more and also if power plant is located away from load center. 4. Cost per unit (cost of generation) is high

To construct new Nuclear power plant following are problem :- 

1. The capital cost of Nuclear power plant is very high as compare to other power plant of same capacity due to reactor. 2. The fuel used is expensive and it must be stored safely. 3. Nuclear waste are redioactive and may cause dengereous amount of radioactive pollution if proper care is not taken. 4. The disposal of radioactive waste is a big problem and is hazards to health for thousands of years. 5. If there is an accident, large amounts of radioactive material could be released into the environment. Causing extensive damage to the mankind,animals and environment. 6. It is difficult to build a plant with 100% safe from radioactive radiation. 7. Generation Cost per unit is more. 

Due to above reasons there is importance of solar power in the energy deficient in India because of following advantages of solar energy:- 

1. No air pollution. 2. Solar radiation is the largest renewable resource on earth. 3. Unlimited quantity of fuel available in day time & is in exhaustible. 4. Power can be generated at the point of utilization so it reduces transmission & distribution cost and losses in it. 5. No fuel storage is required. 6. No fuel transportation cost. 7. No treatment on fuel is required. 8. No waste disposal problem. 9. It works automatically (Not required to start) 10. It saves the fossil fuel (coal, diesel, oil etc.) which are limited available.
