Well I disagree with you, I have been driving Etron since last year and been saving up so much on fuel. Also have solar at home which also reduced my electricity bills. Yes there's no infrastructure now but in future hopefully it will be available for everyone.
R-LNG should be mostly for industrial and commercial use, power plant is not only running by LNG as there are many other power plants such as Nuclear, Hydel, Coal, renewable(wind & solar) & furnace oil plant. All these plants altogether is 40,000mw and many other power plant are still under construction. I think in future electric is way to go and we should promote EVs public transport as well. Btw there's article of ev on today's dawn news.
