The bad old days of gas lines in the 1970s and shortages led to the creation of fuel economy rules.
The Trump administration's move to freeze fuel economy standards reflects a sea change in American energy policy first born during an era of oil shortages and environmental crises.

A recent survey of electric utility leaders finds that Trump administration efforts to promote coal energy and roll back air pollution regulations have had little impact on their long-range plans.
Fuel economy and air pollution regulations have lowered pollution and pushed industry to innovate.
The Trump administration announced a plan to relax fuel economy standards, but well-designed regulations can drive clean car innovations that make U.S. industry globally competitive.

No new oil drilling has been approved since 1984 off the California coast, where a major spill in 1969 helped launch the environmental movement. Sixty-nine percent of Californians oppose offshore drilling today.

A scientist who served on a national commission to review the 2010 BP oil spill explains why Trump administration efforts to loosen offshore drilling regulation pose major risks for minor payoffs.
Making sense of the Department of Energy’s plan.
The Federal Energy Regulatory Commission normally works in obscurity, but is in the spotlight as it considers a proposal to support coal and nuclear power plants that are having trouble competing.
Transportation is the biggest contributor to greenhouse gases by sector. Converting the U.S. fleet to cleaner electric vehicles would likely take decades.

What if the world really got serious about meeting global climate goals? Doing the math on current emissions and the pace of energy transitions shows how quickly fossil fuels need to be phased out.

With better access to energy, women in developing nations could spend more time working or in school. But Energy Secretary Rick Perry's claim that fossil fuels improve women's lives misses the mark.
Grid operators set the prices for energy markets and are structured to take the lowest prices – a disadvantage for coal and nuclear power.
Two moves by the Trump administration signal a dramatic shift in energy policy to favor coal and nuclear, but markets forces and legal challenges mean changes could take years.

The Trump administration is committed to deregulating industry, as it's done with the EPA Clean Power Plan. But a historian shows how regulations have actually benefited both industry and consumers.

Interior Secretary Ryan Zinke calls himself "a Teddy Roosevelt guy," but supports many actions that critics call anti-conservation, such as shrinking national monuments and fast-tracking energy projects.
Coal power has long been a mainstay of the electricity system but has lost share as natural gas prices have gone down.
The Department of Energy's review of the electricity grid finds natural gas, rather than renewables, has hurt coal and nuclear power. But that's only half the story of the changes underway.
