In the wake of its diesel emission scandal, Volkswagen has done its best to portray itself as a cleaner, more thoughtful automaker. Part of the damage control plot includes a slew of new electric vehicles to round out the German automaker's portfolio in the coming years. But, what about the environmental impact and carbon-emission burden of the...
Anniversaries often provide an opportunity to reflect on important past events, review what has happened since, and reflect upon the future. April 2 of this year marks the 10th anniversary of the Supreme Court ruling in Massachusetts vs EPA in which the EPA was forced to regulate carbon emissions. The passing of this anniversary was marked by an...
It's now clear that the zero-emission vehicles of the future will be powered by electric motors. The electricity to power those motors, however, will come from one of two competing technologies: high-capacity batteries or hydrogen fuel cells. The debate over which technology is superior, which has the lowest wells-to-wheels carbon footprint, and...
The Industrial Revolution that started around 1750 in England was powered largely by coal. With Watt's invention of the steam engine and the emergence of railways in the mid-nineteenth century, the carbon-dense fuel was central to the change from an agricultural economy to an industrial one. Last Friday, however, marked a watershed moment for...
Former New York City mayor Michael Bloomberg has gone on record saying publicly what most analysts have discussed privately: the notion that Washington can direct the energy market back towards coal is wrong. In fact, Bloomberg is willing to go further: he believes that the U.S. can still meet the reductions set forth in the Paris climate treaty...
Measuring the energy efficiency of a new vehicle is one thing, but ascertaining its overall environmental impact can be more complex. A debate still rages over the overall carbon footprint of electric cars compared to those powered by fossil fuels. But for the past 20 years, the the American Council for an Energy-Efficient Economy has tried to...
Electric cars are simply nicer and calmer to drive than conventional cars, and as their prices fall, that may be what will lure mass-market buyers over time. But they have undeniable benefit of lowering wells-to-wheels carbon emissions per mile driven, and they can also be powered entirely on renewable energy. Which makes them good for drivers and...
Transitions into new technologies always generate confusion and misinformation, and certainly that has been the case with modern electric cars. Buyers, automakers, and analysts debate their cost, suitability, real-world range, wells-to-wheels carbon footprint, and recyclability, among other issues. Six years after the first modern electric cars...
Cars that run entirely or partly on electricity from a battery pack have no tailpipe emissions, but to judge their overall impact, you have to look at lifetime wells-to-wheels emissions. That includes emissions associated with extracting, refining, and burning the fuel used to make the electricity that recharges them, as well as the same for any...
You have to do more than buy a Toyota Prius, if you want to reverse global warming.
