I believe it has something to do with oil too.
Indian govt is deadly scared of oil sanctions as most of the oil and the related infrastructure is either controlled by the west or their cronies.
Such sanctions can lead to high prices at home and this could cause a lot of trouble which the govt would like to avoid.
We need something like china's green energy push to reduce our dependence on oil and be much more immune to Sanctions.
Also automobile manufactures need to be given a timeline to move to hybrid cars and then EV by the next two decades.
Oil is India 's achilles heel as we are very import dependent.
Finding alternatives will not be easy.
Renewable energy like solar energy offer good potential. The cost of solar photovoltaic cells is coming down making it economical.
Wind energy though very clean is highly dependent on Mother Nature.
The most viable long-term alternative is Nuclear energy.
France sources more than 70% of its energy needs from nuclear power plants.
Setting aside the risk factor it is the most dependable and long-term.
India has vast reserves of thorium and the 3 stage program can give India energy security.
We should do serious research on nuclear fusion reactors as it is the future.
The transport sector consumes the lions share of petroleum and maximum switch over to electric vehicles will save fuel. The import bill will come down.
We also have vast reserves of coal. A cost effective technology to convert coal to fuels like petrol and diesel will reduce the import bill and our dependence on oil.
Lastly I believe we have vast reserves of oil and gas in the offshore. India has a very long coast line and not enough exploration has been done in the adjoining seas and oceans. I am sure that there are more Bombay High like oil reservoirs waiting to be found. One Bombay High discovery cut down our oil import bill by as much as 50% decades ago.
