At what point are companies going to give up on electric and look at other possible alternatives like hydro or something nobody has come up with like converting trash to renewable energy? I still have issues with the environmental impact with electric fuel cell manufacturing and recycling. It's horrible on the environment and the recycling issues (hell, we still have problems just recycling plastics) cause me to doubt electric as a long-term viable solution. Just in case: http://www.theguardian.com/vital-signs/2015/jun/10/tesla-batteries-environment-lithium-elon-musk-powerwall http://www.theguardian.com/vital-signs/2015/jun/10/tesla-bat... In a 2013 report, the U.S. Environmental Protection Agency’s Design for the Environment program concluded that batteries using nickel and cobalt, like lithium-ion batteries, have the “highest potential for environmental impacts”. It cited negative consequences like mining, global warming, environmental pollution and human health impacts. http://pubs.acs.org/doi/pdf/10.1021/es903729a http://pubs.acs.org/doi/pdf/10.1021/es903729a The main finding of this study is that the impact of a Li-ion battery used in BEVs for transport service is relatively small. In contrast, it is the operation phase that remains the dominant contributor to the environmental burden caused by transport service as long as the electricity for the BEV is not produced by renewable hydropower
