Thought was worth putting in article in full, this is the first half, but you get the gist of what is going to happen with batteries, especially trucks and buses

Electric buses were seen as a joke at an industry conference in Belgium seven years ago when the Chinese manufacturer BYD showed an early model.
"Everyone was laughing at BYD for making a toy," recalled Isbrand Ho, the Shenzhen-based company's managing director in Europe. "And look now. Everyone has one."
Suddenly, buses with battery-powered motors are a serious matter with the potential to revolutionise city transport - and add to the forces reshaping the energy industry. With China leading the way, making the traditional smog-belching diesel behemoth run on electricity is starting to eat away at fossil fuel demand.
The numbers are staggering. China had about 99 per cent of the 385,000 electric buses on the roads worldwide in 2017, accounting for 17 per cent of the country's entire fleet. Every five weeks, Chinese cities add 9500 of the zero-emissions transporters-the equivalent of London's entire working fleet, according Bloomberg New Energy Finance.
All this is starting to make an observable reduction in fuel demand. And because they consume 30 times more fuel than average sized cars, their impact on energy use so far has become much greater than the than the passenger sedans produced by companies from Tesla to Toyota.

​

For every 1000 battery-powered buses on the road, about 500 barrels a day of diesel fuel will be displaced from the market, according to BNEF calculations. This year, the volume of fuel buses take off the market may rise 37 per cent to 279,000 barrels a day, about as much oil as Greece consumes, according to BNEF.
"This segment is approaching the tipping point," said Colin Mckerracher, head of advanced transport at the London-based research unit of Bloomberg. "City governments all over the world are being taken to task over poor urban air quality. This pressure isn't going away, and electric bus sales are positioned to benefit."
China is ahead on electrifying its fleet because it has the world's worst pollution problem. With a growing urban population and galloping energy demand, the nation's legendary smogs were responsible for 1.6 million extra deaths in 2015, according to non-profit Berkeley Earth.
A decade ago, Shenzhen was a typical example of a booming Chinese city that had given little thought to the environment. Its smog became so notorious that the government picked it for a pilot program for energy conservation and zero emissions vehicles in 2009. Two years later, the first electric buses rolled off BYD's production line there. And in December, all of Shenzhen's 16,359 buses were electric.
