wishful Thinking! You cannot increase the other 3 modes of power production. Thermal is surely out of question because of Global warming. Hydel..where do you plan to put water dams? if we do it then the Narmada Baccho andolan starts... besides most of the indian rivers are in poor state especially during the summer. Solar and Wind power are in very early stages of development. maybe after 10 yrs we might have the technology to exploit these sources but not as of now. Nuclear is the only viable option as of now. Most of the western countries are using Nuclear power without any problem. there are risks in everything we do but it doesnt mean that we just stop do it.
