Mass adoption of electric cars and renewable energy could significantly decrease global consumption of fossil fuels. But does the traditional energy industry view these new developments as a threat?
Because the Environmental Protection Agency's rule-making follows a prescribed procedure that includes lengthy technical analyses and public input, all of it based on science, eliminating its fuel-economy standards will not be simple, some say.
So far only a relatively small number of settlement vehicles can be modified to meet emissions standards and stay on the road.
If electric cars are adopted by mass-market buyers in years to come, that will lead to notably lower oil consumption. So what are oil companies doing to prepare for that possible outcome?
Before the concept of low-carbon or carbon-neutral fuels even existed, people tried something completely different: wood. It powered many of the earliest combustion vehicles, including locomotives and steamships.
The new facility will be located in General Motors's existing battery plant in Brownstown, Mich. and is expected to begin mass production around 2020.
Over the last year, Paris has instituted strict curbs on older cars in an effort to ban those with the worst exhaust emissions. Now French authorities will make it easier for police to distinguish among otherwise identical cars in the streets to find engines fitted with older and weaker emissions-control systems.
Given Germany's considerable investment in its auto industry, using a German car seems almost obligatory for government officials. Yet one environment minister is causing a stir by challenging that tradition.
From the perspective of both renewable-energy advocates and electric utilities, grid-scale energy storage offers many potential benefits. Yet energy storage has not been tested on a large scale by US utilities. Until now.
Republican legislators recently introduced a bill that would essentially ban large-scale renewable energy in the state by 2019.
Other countries have no intention of rolling back their emission limits. This means that any changes Trump makes in the US could be offset by laws elsewhere.
With US headlines about the latest on emissions cheating from Volkswagen, and now an investigation of Fiat Chrysler, the past week has not been a great one for diesel cars. Now, two automakers are subject to diesel investigations in Europe.
Tesla said in November that it would end free unlimited use of its Supercharger DC fast-charging stations. Now the company is offering more details on Supercharger pricing.
The future of the technology in the US appears to be manufacturers using diesels to improve efficiency in trucks, while turning to electrified powertrains to do the same in passenger cars.
The Bolt snags an award that doesn't often go to 'green' vehicles.
According to one study, average electric-car battery costs declined every year between 2010 and 2015.
