California Seeks Fully Emission-Free EVs With 100 Percent Renewable Energy

GM signed an agreement with Renewable Energy Systems to source 50 megawatts of wind energy to power 16 sites with 100 percent renewable energy

When you are driving an electric vehicle, its day-to-day operations are often only as clean as how your electricity company makes it. So, if you charge your car off your own roof-mounted array of solar panels, you are polluting far, far less than someone charging their car in the Midwest on a coal-fired plant.

Now, though, California, already ahead of most states in green energy, is set to make its electrics as emission-less as possible, with a bill that will require state electricity to be 100 percent renewable by 2045. The legislature passed the bill last week.

Unsurprisingly, there are some serious problems to overcome. The largest is energy storage. Like you might expect, during the day California gets a giant amount of solar energy, and critics point out that current batteries can’t charge fast enough to retain that huge bumper crop of electricity. All in all, they argue, making 100 percent of the state’s electricity from renewable sources just isn’t cost-effective.

Of course, not all agree. Several power producers are deploying fast-charging batteries already, and others still point out that, while right now it may not be easy to pay for this change, 2045 is still 27 years away. At that point, we will have a lot of new, better technology that could feasibly handle this task.

One possibility is floating turbines, which rely on winds off the coast that are more consistent than those on land. However, 27 years is plenty of time for all the amazing energy and battery technology that we like to see to move from a prototype in scientific journal to actual production.
