How electric planes are changing flight

It is fascinating to consider the advances in transport I've witnessed over my 73 years. Some sort of 'batteries/e-power' will be the relatively distant future of aviation. Physics is physics and fossil fuel still maintains some 5000% per pound energy edge over the battery, but that continues to slowly shrink.  Also the current power grid being what it is, substantial numbers of fossil/coal/nuclear plants must be built soon to supply the energy to charge all these new battery powered cars and planes. Few such plants are on the drawing boards today. I've seen an estimate that if the entire surface of the United States were covered in solar panels, it wouldn't supply even half the present U.S. electricity demand. Battery technology demands recharging capability at a level that doesn't really exist large scale.
