Seattle-based startup Zunum Aero has received funding from Boeing HorizonX and JetBlue Technology Ventures toward making its dream of electrified air travel a reality. Sometimes billed as the Tesla of the airplane industry, Zunum is developing a relatively small regional aircraft with about 700 miles of range. A 1,000-mile range will be attainable...

Despite some alarmist reporting, President Donald Trump hasn't abolished the EPA's vehicle emission limits. Nor has he wiped out corporate average fuel-economy rules, set by the NHTSA. So far, he's done two things: signed an executive order reopening the comment period for 2022-2025 EPA emission limits, and proposed a budget that would slash EPA... 
If you have your eyes on a used Volkswagen or Audi TDI turbodiesel, you may wind up having to pay more today for 2009 through 2015 models than you would have when they were new. At least right now, only 2015 model-year versions of VW and Audi vehicles sold with the 2.0-liter turbodiesel 4-cylinder TDI engine can be modified to comply with... 
The prospect of ongoing operations as usual continues to darken for the Environmental Protection Agency. According to a detailed internal budget document published in the The Washington Post, the Trump administration wants to eliminate virtually all federal funding for the agency’s vehicle emissions and fuel-economy testing budgets. If the... 
The new U.S. president, Donald Trump, is working to eradicate every Obama policy to limit the carbon emissions that contribute to climate change. Having variously called the science behind climate change a "Chinese plot" to hurt the U.S. and referred to it using an expletive for bovine excrement, this shouldn't come as a surprise. He pledged to do... ![The White House, Washington, D.C. [Creative Commons license by dcjohn]](http://images.hgmsites.net/tmb/white-house_100170583_t.gif)
These do not appear to be the best of times for President Donald J. Trump, but his agenda of eliminating regulations and promoting fossil fuels continues to roll out. This week, Trump appeared at the EPA to sign an executive order that directed the agency to reopen and reassess its Clean Power Plan for reducing carbon emissions from generating... 
Natural gas is growing as a part of the world's grid mix, because its carbon per kilowatt-hour is much lower. But methane leaks that emit large volumes of climate-change gas into the air may offset that advantage. Now, a Google Street View car has allowed researchers to pinpoint and quantify the severity of natural-gas leaks in five different... 
Given the current political landscape in Washington, it's not unreasonable to worry about the future of U.S. efforts to combat climate change. The Trump Administration has embarked on an explicit mission to undo all Obama Administration efforts to reduce carbon emissions. Climate-science deniers in the current administration include Trump himself... 
While renewable energy gets significant press as an alternative to coal in electricity generation, it isn't the main factor in decreasing the use of that carbon-intensive fuel. Thanks to its generally lower cost, natural gas is quickly displacing other fuels in the nation's power plants. In addition to its cost benefit for electric utilities...
