Write a report. 
Electric cars had long been championed by environmentalists as a superior solution to the  internal combustion engine (ICE), but, despite large government incentives and strong  pioneering efforts by a few automakers over the years, electric and hybrid cars and light  trucks still accounted for less than 1% of total global production in 2016. However, events  took a turn in 2017 and 2018, when many governments committed to banning ICE vehicles.  In response, leading automakers announced plans to launch hundreds of electric vehicle  models within five years. Early pioneer Tesla, which, in 2017, had built a stock market valuation exceeding that of General Motors (GM), despite only delivering 103,000 cars  compared to GM’s 9.0 million, looked as if it were about to be engulfed by this new  competition. But not all were convinced that electric cars would soon displace conventional  ICE vehicles. It was not clear that the infrastructure was in place to charge all these electric  vehicles. There were also questions concerning the electrical generating capacity to meet  the new demand. Would battery prices fall enough to make mass-market demand a  possibility? In low gasoline cost jurisdictions, such as the United States, the economics of  owning an electric vehicle didn’t appear justified, unless subsidies were maintained  indefinitely. In Europe, where gasoline taxes were high, the case for electric vehicles was  stronger. But European governments depended on those taxes to meet their budget needs.  Would a significant uptake of electric vehicles necessitate higher taxes on electricity? In  2018, electric cars were an expensive novelty for the rich subsidized by the poor. Would  the sudden rush of new models change the balance?
