Here’s how to meet Biden’s 2030 climate goals and dramatically cut greenhouse gas emissions – with today’s technology

  Unprecedented forest fires in the drought-stricken western United States. Tropical storms and rising seas threatening the Gulf and Atlantic coasts. Sizzling heat across large swaths of the country. As climate change unfolds before our eyes, what can the U.S. do to sharply and rapidly reduce its share of the greenhouse gas emissions that are causing it?

  The Biden administration has committed to reduce those emissions 50% by 2030 below 2005 levels. That’s a critical first step of a global energy transition that must achieve net-zero emissions by midcentury to limit warming to 1.5 degrees Celsius (2.7 F) and thereby avert the worst impacts of climate change.

Climate change is an infrastructure problem – map of electric vehicle chargers shows one reason why

  Most of America’s 107,000 gas stations can fill several cars every five or 10 minutes at multiple pumps. Not so for electric vehicle chargers – at least not yet. Today the U.S. has around 43,000 public EV charging stations, with about 106,000 outlets. Each outlet can charge only one vehicle at a time, and even fast-charging outlets take an hour to provide 180-240 miles’ worth of charge; most take much longer.

  The existing network is acceptable for many purposes. But chargers are very unevenly distributed; almost a third of all outlets are in California. This makes EVs problematic for long trips, like the 550 miles of sparsely populated desert highway between Reno and Salt Lake City. “Range anxiety” about longer trips is one reason electric vehicles still make up fewer than 1% of U.S. passenger cars and trucks.
