My new post: Electric vehicles have become crucial to the effort to reduce greenhouse gas emissions. A new bit of modeling shows that, for Colorado, electrifying vehicles could reduce as much emissions as decarbonizing the entire electricity sector.  https://www.vox.com/energy-and-environment/2019/8/12/20801602/colorado-electric-vehicles-2019-renewable-energy?utm_campaign=drvox&utm_content=chorus&utm_medium=social&utm_source=twitter 

My post today shows that EVs are a powerful decarbonization tool. People have been asking, "what about on grids with lots of coal?" Two things on that. First, UCS has shown that EVs have lower lifecycle emissions *across the US*, with every grid mix, already.

Second & more broadly, EV policy is undertaken on the assumption that clean-electricity policy will unfold alongside it. It's a bet that the grid is *getting cleaner* & will continue doing so. It's one of the coolest things about owning an EV, namely ...

... in terms of environmental performance, it will *get cleaner the longer you own it*, as US grids get cleaner. An ICE vehicle is as clean as it will ever be the day you buy it. Gasoline=carbon; that will never change.

It's true for all electrical appliances/systems, from heat pumps to toasters to arc furnaces: as the grid gets cleaner, they all get cleaner too, automatically. Pretty nifty!
