Electric cars: Boom or bust?

September 25, 2024 By EarthWise Leave a Comment

Media coverage of electric cars in this country is pretty confusing. Are electric cars taking over or has the EV bubble burst?

EVs currently represent about 8% of the US new car market. But they continue to face some relatively unique headwinds in this country. A very powerful and influential oil industry makes sure that anti-EV stories occupy center stage in the media. Traditional car dealers don’t want to sell EVs because they don’t make much money from parts and service. And EVs often find themselves tangled up in American politics.

Meanwhile, the rest of the world tells a very different story. Globally, EVs constitute 20% of new car sales, but in some places, they are doing much better than that.

So far this year, almost 87% of new car sales in Norway are electric and in August, the figure was 94%. Norway has some incentives in place for EV owners, but the fact that nearly all new cars on the road are electric is far more than the result of incentives.

One might argue that Norway, a country with only 5 million people, faces a much easier task of transitioning to EVs. But how about China with its 1.4 billion people? In July, plug-in vehicles in China were 51% of new auto sales. And the numbers continue to rise.

There are plenty of articles out there explaining why electric cars just can’t meet people’s needs, have insurmountable problems, and how having too many of them would collapse electric grids and otherwise wreak havoc with society. Apparently, the Norwegians and Chinese, among a growing number of other countries, haven’t gotten the memo.

Driving Electric Is Cheaper For Almost Everyone | Earth Wise

February 24, 2023 By EarthWise Leave a Comment

A study by University of Michigan researchers found that about 90% of U.S. households would save money on fuel costs by owning an electric car rather than a gas-powered car. So apart from the environmental benefits of electric cars, there are real economic benefits as well.

Both the price of gasoline and the price of electricity vary considerably across the country, so there are differences by location. The study found that 71% of U.S. drivers would see their fuel expenses cut at least in half by driving an electric car.

Drivers in California, Washington, and New York would see the largest fuel savings as well as the biggest emissions reductions from a new electric car. Those states have cleaner electric grids and a bigger gap between the cost of electricity and the cost of gas.

The study, published in the journal Environmental Research Letters, only looked at fuel costs and did not take into account the purchase cost of new cars. Generally speaking, plug-in cars have higher sticker prices than gas-powered cars but multiple studies have shown that over their lifetimes, electric vehicles end up being cheaper to own than comparable gas-powered vehicles because of lower maintenance costs on top of the fuel savings. The price gap between equivalent gas and electric cars continues to narrow in any case as the cost of batteries continues to decline. On top of that, the recent expansion of federal tax credits on electric cars is making the vehicles cost-competitive right at the point of purchase.

Gasoline prices have come down considerably from their peak a year ago, but for almost everyone, it is still much cheaper to drive on electricity.

Improving Energy Storage

June 22, 2017 By EarthWise

The transition to sustainable energy sources faces many challenges. One important one is to make those sources as reliable as conventional energy systems. For technologies like solar and wind power, which can’t operate around the clock, an enabling element is effective energy storage. Energy storage is critical for both the electricity grid and for transportation.
