One of the niche key to power saving is by increasing equipment efficiency.
Promote the production of LED distribute it among the public with subsidy.
Decrease taxes on 5 star equipment.
Make standalone equipment like Solar Street lamp in village's.
Subsidise solar panels so that people can use it in their houses and Farms.
The key is Decentralisation of each and everything.
Further Gov should invest in R&D for research is cost cutting method in Electric transmission and production.
R&D to increase efficiency of Solar panels, Nuclear reactors, Hyrdo, Wind.
Ya'll Nibbiars and even with that the BEV suffer from the following problems.
1 . Inherent Carbon Emission's. And even without lithium Ion batteries which are not going anywhere soon. I am hearing this for a decade.
2 . Loss of energy during the Transmission. Which is hard to reduce even with improving in the Infrastructure specially in India which is happening slowly.
3 . The Law of Diminishing Return's.
4 . The emission would be still only be reduced by 77 percent at most even with other source of energy and environmentaly friendly manufacturing processes. Get this notion of 100 % clean energy there is nothing like that.
5 . And why you want to carry heavy batteries with you?. Even it's weight is reduce the overall weight will remain the same in order to increase the range. And that's not a efficient way.
And I have more hopes for the Bio Fuel and FCEV. Sorry this is my personal opinion's.
