Battery technology is advancing rapidly. Significant improvements in specific energy and safety will see electric propulsion become the norm for road vehicles and light aircraft within a few years.
But there is no point in electric vehicles unless the electricity is low carbon. Wind and solar power are coming down in price and will make a major contribution but the so called "renewables" will not meet the increased demand for electricity on their own. New generation nuclear technology (such as this

Climate change luddites believe that the planet can only be saved by giving things up and massively changing lifestyles. They don't believe that new technologies will enable us to continue doing the things we want (such as driving cars and flying aircraft) without destroying the planet.
