Continuing low gas prices are often blamed for the current popularity of crossover utilities and SUVs, along with any sales struggles green cars may experience. But would a sudden increase in gas prices cause shoppers to flock to more fuel-efficient vehicles? If so, how high would gas prices have to get in order for consumers to start changing... Gas has to cost $3 a gallon before it affects vehicle choice, study says
Continuing low gas prices are often blamed for the current popularity of crossover utilities and SUVs, along with any sales struggles green cars may experience. But would a sudden increase in gas prices cause shoppers to flock to more fuel-efficient vehicles? If so, how high would gas prices have to get in order for consumers to start changing... 
For nearly a decade, the average fuel economy of new cars sold in the U.S. steadily increased—but that moment has stalled in recent years. Low gas prices and increased consumer interest in SUVs has caused new-car average fuel economy to plateau and, in the case of 2016's figures, decline slightly. The average fuel economy of new cars sold in... 
High costs of lithium-ion battery cells have been one of the main hindrances to large-scale electric-car adoption, as they typically lead to higher purchase prices for electric cars than comparable internal-combustion models. But electric-car battery prices are falling fast, according to one recent study. Global Trends in Renewable Energy, calls... 
It's well known by now that the European Union testing protocol for fuel economy is much less rigorous than the U.S. Environmental Protection Agency (EPA) standards. Both protocols are based around laboratory testing rather than real-world evaluation, but EU figures have gained a reputation for being much more optimistic than what drivers can... 
Over the past few years, the cost of electricity generation from renewable-energy sources has decreased dramatically. So much so, that renewable energy may have just hit an important milestone, according to one study. In the U.S., wind and solar power are now cheaper sources of electricity than natural gas—even without subsidies. DON'T MISS... 
There's been considerable debate among advocates of battery-electric and hydrogen fuel-cell cars over which technology is better for the environment. While neither vehicle type produces any tailpipe emissions, their overall emissions vary depending on the fuels and processes used to generate electricity or produce hydrogen. A new study indicates... 
It's entirely obvious that internal-combustion cars pose a threat not only to the environment, but also to human health. Exhaust from gasoline and diesel cars contributes to air pollution that can lead to deleterious health effects after long exposure. Now a new study from the American Lung Association in California aims to quantify the health... 
Stricter global emissions standards are putting significant pressure on carmakers to improve fuel efficiency and make greater use of electric powertrains. But that may not be the sole force driving automakers toward reduced carbon emissions. Cutting emissions is also a priority for at least some of their investors, it seems. DON'T MISS: India, EU... 
Within the next 15 years, the world's wealthy cities could be teeming with electric cars. That's the prediction of a new report, which claims electric cars could account for two thirds of the cars on the roads of 50 major world cities by 2030. Researchers predict that a combination of growing consumer interest and stricter emissions standards will... 
Perhaps an even greater challenge than getting today's car buyers to switch to electric cars is predicting the rates of adoption among those who have yet to buy their first car. But attracting younger buyers will be crucial for the mass adoption of electric cars in future years. A new survey offers some encouraging results, at least for automakers...
