Electric cars: Boom or bust?

September 25, 2024 By EarthWise Leave a Comment

Electric cars are booming

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.

electric vehicles as a battery resource

Transportation accounts for nearly a quarter of the direct carbon dioxide emissions coming from burning fuel.  As a result, electrification of transport is one of the major ways we can reduce emissions.  Increasing the number of electric vehicles over time is essential for meeting emissions targets.

But electric vehicles have the potential to do more than deliver emissions reduction; they can also provide other energy services.

More and more electric cars provide over 200 miles of driving range, but most cars are actually driven no more than 30 miles a day.  As a result, the fleet of electric cars represents a huge bank of energy stored in battery packs and mostly sitting around unused.  This presents an opportunity to leverage this resource.

Car battery packs could be used to absorb excess renewable energy generated in the middle of the day (for example from solar installations) or at night (from wind farms) and potentially then to export stored energy to power homes and support the grid.  This energy system is known as V2G, or vehicle-to-grid technology.

The University of Queensland in Australia has launched a unique international trial to see if the spare battery capacity in vehicles could be used for these purposes.  The university has partnered with Teslascope, which is an online analytics platform used by Tesla owners to track the performance of their cars.  Tesla owners wishing to be part of the study authorize the collection of their data and, in turn, receive a free 12-month subscription to the Teslascope service.  The study will collect data from Tesla owners in Australia, the US, Canada, Norway, Sweden, Germany, and the UK.
