TL;DR The question is no longer if we'll make it, just when.
* Solar and wind are stupid cheap now, and getting cheaper, fast. In over 25 states, rooftop solar is a better investment than the S&P500. [1] You're seeing Power Purchase Agreements under 3 cents/KwH. [2] Solar will only get cheaper. Wind is still being built like crazy in Texas and the central Midwestern US. Some utilities even offer power for free at night wind power is so plentiful (and transmission capability lacking). [3] Tesla/SolarCity has already moved into Florida now that the utility-sponsored Amendment 1 failed. (Which was an underhanded utility attempt to hinder rooftop solar deployment)
* Utility scale battery storage has arrived. Again, its only going to get cheaper (Tesla's Gigafactory is a big deal, but lots of other players in the market as well) [4] [5] [6]. Tesla has already installed a microgrid on an island in the Pacific that satisfies all of the island's power needs, removing the need for their diesel generators to produce island power.
* Tesla will deliver its Model 3 in the next 12-18 months. I have no doubt Elon will drive Tesla into scaling up to 1 million vehicles/year in production (relying primarily on their recent German manufacturing automation acquisition) [7]. While I would like to see Nissan and GM make EVs that aren't purely compliance cars (Bolt? Pleasssssse), I think they're good enough for urban dwellers or car share networks where you're sticking to major metros. (Full disclosure: TSLA investor)
* OPEC has finally agreed (after 8 years) to reduce supply to push oil prices back up. Even with US shale coming back online at those profitable market prices ($60-80+/barrel) and some of OPEC cheating on those cuts (who wants to reduce their revenue artificially?), that only does one thing: accelerates the transition to EVs. [8]
* Repealing the Clean Power Plan will not be able to stop the phase out of coal power due to cheap natural gas. Market forces at work. [9]
* Federal electric vehicle subsides will phase out within the next 2 years for all manufacturers due to hitting the sales quotas dictated by the statute's phaseout provisions [10]. No point in trying to remove them.
* Solar and wind ITC tax credit extensions (to 2021) agreed to by Congress were bipartisan. In exchange, restrictions were removed on the export of crude oil from the US. This agreement will not be unwound.
