News & Articles on Electric Vehicles
We’ve made great strides in moving the electricity sector toward renewable energy. However, transportation remains a major source of air pollution and global warming gases. If we are to make a transition to renewable energy, we will need to electrify as much of the economy as we can, including transportation. Electrified rail is one means, electric vehicles (EVs) are another. The focus here is mostly on our experience driving EVs. We’ve been driving electric since the fall of 2014.
Amost nine years ago I wrote a series of articles explaining why we chose to drive electric. These essays were …
In this post, I crunch through all the data on the carbon footprint of EVs compared to conventional fossil cars. The summary is that, yes, EVs emit less – often one-half to two-thirds less over their lifetime. EVs still emit less when the battery is produced in countries that rely heavily on coal. And, this is true, regardless of whether you’re thinking about buying a new car, or a second-hand one. As the world moves towards lower-carbon electricity, the emissions of EVs will fall even more. When run on renewables or nuclear, the footprint of EVs could be tiny.
Batteries’ domination is likely to be extended as the money pouring into research and infrastructure addresses questions of range and charging times. Compared with that flood of investment, hydrogen is a trickle. Hydrogen’s advocates now face the question of whether they can build profitable businesses in longer-distance, heavy-duty road transport. They need an answer soon on where they will source enough green, cheap hydrogen – and whether the gas would be better used elsewhere.
As U.S. EV sales rise, more cars than ever are using the electrical grid to power up. It would be reasonable to assume that means the grid must now supply a vast amount of energy to those cars — but it actually won’t take as much as you might think. The reality: EVs require much less energy to operate than gasoline-burning vehicles. In fact, with the nation’s current electricity blend, an EV requires only about half the energy needed for a gasoline-powered internal combustion engine.
