I thought you would never ask.

It is indeed easy. The world could switch to renewables like solar energy, wind energy, hydro, tidal energy and nuclear energy. It just takes time and money.

Currently electrical vehicles are gaining in application and acceptance. Even if electric vehicles operate from fossil fueled power generation, the vehicles themselves are more energy efficient efficient than traditional combustion engine vehicles. Furthermore, power station conversion rate of fuel to electrical energy is 55+% - 75+% (combined cycle heat recovery) compared with car combustion energy conversion rate of about 29%.

Working on Tesla supposedly 230 miles on 60 kWh battery, a Toyota Camry would require 9.3 US gallons for 230 mile range which has an energy equivalent 307 kWh. Therefore an electric vehicle uses about 20% partly because of combustion engine inefficiency and partly because electric vehicle recovers energy which is otherwise dissipated by brakes with a combustion engine. The disparity is far higher for stop-start city driving where fuel consumption of combustion engines greatly increases.

Please don't thank me.
