Public utility officials in New York released a grid proposal this week in support of 100% clean electricity by 2040, warning that a crop of massive wind farms could otherwise be left stranded in the state.

The grid may still be too coal-heavy in some parts of the United States for electric vehicles to be a better option for local air quality than gas cars, according to an analysis published yesterday by scientists at Lawrence Berkeley National Laboratory and Stanford University.

The world lacks the technological capacity to cut as much as three-quarters of global CO2 emissions by 2070 and will have to invest about $350 billion per year over the next two decades to develop new energy technologies, the International Energy Agency warned in a report last week.

The Trump administration took a step toward slapping new tariffs on imported wind towers this week, despite warnings from the U.S. wind industry.

Electric cars will likely have to sacrifice range if they're also self-driving, but not so much that automakers will need to include gas engines as an inevitable part of autonomous models, according to a new study.
