Electric vehicles (EVs) don't make much noise on the road, but they're generating a lot of buzz about the future of this technology and what it means for business and the environment.

Cars, buses and trucks are the second biggest source of pollution in the U.S. after electricity production. They are responsible for more than 26 percent of emissions that adversely affect the health and well-being of the population, and put communities located close to highways and other major thoroughfares at risk. These communities, typically low-income, are often plagued by elevated asthma rates and other pollution-induced health conditions.

When thinking about ways to reduce pollution, EVs can make a world of difference. And, when charged using renewable energy sources, they produce no emissions and can be much cheaper to operate than traditional, internal combustion vehicles. As such, let's take a look at the global EV market and impacts in the U.S. on the electric grid in two environmentally progressive states—New York and California.

The Global Market—and Future Outlook

More and more automakers are shifting their focus to EVs, a market that is expected to grow faster every year. A few examples:

• Tesla invested $5 billion in its Nevada gigafactory—where they will make batteries for EVs—and is grabbing headlines with the roll-out of its first mass-market EV, the Model 3.

• Volvo made waves by announcing its intent to focus new vehicle production solely on electric and hybrid vehicles. The company is owned by Geely Automotive holdings, a Chinese firm, and many speculate that China's pervasive air pollution problems and a desire to find a long-term solution were a motivating factor behind the announcement.

• Mercedes Benz is investing $740 million in a new battery factory.

These exciting developments all point to a trend where electric cars are much more than just a niche—indeed, they show that global competition is heating up quickly and that companies around the world see EVs as key to the automobile industry. These movements should not be understated, as it gives a hint of a clean energy future that can't come fast enough.

EVs on the Grid

Overall, strategic deployment of charging stations will be essential to EV growth—drivers need convenient places to charge. What's more ...

Here's what we can do now to prepare for a clean car economy:

• Chase innovation: Testing out more nascent technologies, such as vehicle-to-grid capabilities, will ultimately help make EV charging more convenient and ensure the electric grid can cleanly and reliably handle a significant uptick in electrified transport.

• Educate consumers: Utilities must ensure their customers are well-positioned to take advantage of EV benefits by educating them about how their charging behavior can impact the grid and the integration of renewable energy. More specifically, utilities must exercise load management via well-designed rates and other means in order to ensure their customers are charging their vehicles at times when renewables (rather than fossil fuels) are abundant and when the grid can best handle it. By reaching out to their customers through multiple means and languages, utilities can better ensure the robust participation needed in order to bring success.

• Emphasize vulnerable communities: Plans must genuinely consider benefits to and impacts on communities most likely to be harmed by pollution. Environmental Defense Fund (EDF) recommends a minimum percentage of charging stations be placed in these communities where applicable, and that all projects focus on enhancing transportation electrification in areas positioned to benefit them most.

New York

Earlier this year, New York State committed to the purchase of two thousand electric vehicles by 2025, more than doubling its current fleet of government automobiles.

New York is also doing its share to expand electrification to make it easier for customers to buy and use electric vehicles. The State's Reforming the Energy Vision aims to align utility needs with marketplace innovations, and is doing the following:

• Decentralizing the electric grid so customers can make and buy renewable energy, New York is working toward a future where EVs and less pollution are commonplace.

• Developing favorable electricity rates to encourage charging of EVs at times when renewable energy is readily available and affordable. This way, EV adoption will benefit the grid and the environment.

Con Edison's Smart Charge NY program, an early stage effort in New York City, is paving the way for mainstream EV use; the results will be an example for how other cities can adopt the policies and tools necessary to seamlessly integrate EVs.

California

With more than 300,000 EVs and more than 12,000 charging stations, California leads the nation in clean car sales. Moreover, that number is poised to grow rapidly—California EV sales rose 91 percent in the first quarter of 2017 from the same time last year.

Even in the face of threats from the current U.S. Environmental Protection Agency head Scott Pruitt to take away California's waiver allowing the state to exceed national clean car standards, the Golden State has made clear its progress won't be stalled anytime soon. State legislators, cities and agencies have taken a tremendous amount of initiative on EVs, including:

• The California Air Resources Board has reaffirmed its commitment to maintaining stronger vehicle emissions standards.

• Volkswagen updated its plan for investing $800 million to accelerate electrified transportation in California, with input from the California Air Resources Board.

• Senate Bill 350 prioritizes widespread transportation electrification.

• In Los Angeles, half of all municipal vehicle purchases will be electric starting this year, and that share will increase to 80 percent by 2025. The city is also moving forward with a pilot EV ride share program to extend their benefits to communities with fewer car owners.

Moreover, as part of Senate Bill 350, investor-owned utilities filed applications with the California Public Utilities Commission for investments in light-duty, medium-duty and heavy-duty sectors.

The utility plans in particular represent an exciting new opportunity to accelerate electric transportation in all its forms. With planned projects from placing charging infrastructure for passenger EVs in single family homes, to providing car dealers with incentives and education to sell more EVs, to electrifying buses and ship ports—and everything in between—these plans are well-designed to clean the sector most responsible for harmful emissions.

Still, changes to the utility proposals would further strengthen them. EDF recommended to the California Public Utilities Commission that the plans focus more on load management as well as the other key elements listed above.

Forging Ahead

Despite obvious benefits, widespread EV adoption around the U.S. faces a number of challenges. For example, some analysts believe that even California will need another 200,000 charging stations to properly serve the number of EVs expected by 2030.

The internal combustion engine has had a long run, but it's about to burn out. As we work to address domestic barriers to EV adoption, it is important to note that even if it is a global effort, this is a race the U.S. may need to catch up on. As the electric vehicle market continues to flourish, EDF will continue to advocate and make sure environmental benefits follow financial rewards.
