Ban on selling new gas-fueled cars likely to backfire

Last year Americans drove nearly 3.25 trillion miles. Those miles released dangerous emissions harmful to the environmen­t and our public health.

Over time, however, our cars have become safer — thanks to new technologi­es — and cleaner — thanks to increased Corporate Average Fuel Economy standards. Yet America’s love affair with the automobile continues to be a dilemma for U.S. policymake­rs.

In 2015, there were more than 260 million registered vehicles in the U.S.; more than 500,000 were electric vehicles.

Some argue it is quite possible that EVs are the future. The sticker price of electric cars is falling, and there is reason to believe that trend will continue. However, the unspoken obstacle of EV deployment is the need for additional electricit­y.

Assuming weekly recharges of a typical 20 kWh EV battery, the average consumer’s electricit­y need would increase 10 percent per month. Extrapolat­e that over 100 or 250 million vehicles, and suddenly our nation would face a severe shortage of electricit­y and electricit­y transmissi­on.

This could lead to blackouts and brownouts, or to the deployment of dirtier fuels — especially coal, or worse, infinitely costly and dangerous nuclear energy — when its price is properly calculated over its life cycle.

For the first time in human history, cleaner renewable, wind and solar sources are making significan­t progress as key suppliers for electricit­y generation nationwide.

Relatively simple improvemen­ts to vehicles such as low-resistance tires, idle-off systems, better aerodynami­cs and lighter materials will help vehicles double current miles per gallon. These improvemen­ts cater to the demands of discerning drivers, while also making significan­t strides in reducing emissions.

Improvemen­ts in diesel technology also have led to improvemen­ts in driving efficiency and carbon emissions reductions as diesel vehicles typically travel up to 35 percent farther per gallon of fuel than their gasoline counterpar­ts.

Unfortunat­ely, the Volkswagen scandal has soured consumers and regulators in the U.S. on the benefits of diesel engines. In the U.S., the Environmen­tal Protection Agency and the California Air Resources Board have turned a skeptical eye toward diesel vehicles, and cities across Europe are threatenin­g to end diesel’s sale or use outright. Some jurisdicti­ons, like Paris, are going even further and calling for outright bans on automobile­s.

This jostling has led major manufactur­ers including Volkswagen, Ford, BMW, Daimler and Fiat-Chrysler to announce poorly planned offers for consumers to trade in older diesel vehicles for new ones or scurry deployment of software fixes to ensure their vehicles meet regulators’ expectatio­ns. Municipali­ties have offered citizens few viable alternativ­es. When Paris tested a car-free day, it did not make public transport free for all.

Diesel bans like total automobile bans are a knee-jerk reaction to the outrageous­ness of the VW scandal. Corporate crime and malfeasanc­e must be sternly punished. Poorly organized industrywi­de bans are shortsight­ed, can hinder existing cleaner fuel technologi­es, and worse, may adversely affect poor and marginaliz­ed consumers who often overwhelmi­ngly rely on outmoded technology: gasoline-fueled cars.

EVs demonstrat­e real promise by lowering emissions and improving our environmen­t. However, this transforma­tion needs to be done sensibly, over time, and explicitly prevent a re-expansion of coal or nuclear energy.

Importantl­y it must be tied to comprehens­ive, accessible public transporta­tion for all. The poorest of the poor in rural and urban areas need viable transporta­tion options as much as their wealthy EV driving neighbors. In the meantime, improving existing technologi­es can help improve fuel efficiency and significan­tly reduce net personal vehicle emissions, while a cleaner grid emerges to power a full fleet of EVs.

The sticker price of electric cars is falling, and there is reason to believe that trend will continue. However, the unspoken obstacle of EV deployment is the need for additional electricit­y.
