Vox: California has a climate problem, and its name is cars

The state’s pursuit of advanced energy has also yielded an employment bonanza. For every job in fossil fuels, the state boasts 8.5 jobs in renewable energy. And an innovation bonanza: California leads the 50 states in patents in most areas of clean energy.

Perhaps the most notable success of all is California’s incredible progress in becoming more energy-productive — that is, in squeezing more GDP out of every unit of energy consumed. It has recently become the most energy-productive major economy in the world. [...]

The culprit for the slowing decline is a spike in transportation emissions. There was a dip in transportation emissions starting around 2008, with the recession. And though vehicles have gotten more efficient and more hybrids and EVs are on the road since then, the number of vehicles and vehicle miles traveled (VMT) have begun rising again, overwhelming efficiency gains. [...]

The other solution to passenger vehicles is reducing commuting times by solving that housing crisis, and getting people out of their cars by increasing infill and density via building out proper public transportation systems (which themselves will need to be electrified). Unfortunately, cheap gasoline lately has meant a decline in per capita public transportation use in almost every major California city.
