The industrial revolution that began around 1750 was powered in large part by coal, and the carbon-rich fuel had 200 good years after that. By the middle of the last century, however, serious studies had begun of its deleterious effects on human health—and that was before the climate-change impact of human emissions of carbon dioxide became... ‘Fossil fuels are dead,’ says CSX railroad chief: no more new trains for coal, ever
The industrial revolution that began around 1750 was powered in large part by coal, and the carbon-rich fuel had 200 good years after that. By the middle of the last century, however, serious studies had begun of its deleterious effects on human health—and that was before the climate-change impact of human emissions of carbon dioxide became... 
The United Kingdom will follow in the footsteps of some European countries as it announced plans to ban the sale of gasoline- and diesel-powered cars by the year 2040. The initiative closely follows a similar announcement from France, which also declared 2040 as the year it will phase out fossil-fuel vehicles Norway and the Netherlands have also... ![Tesla Model S at Supercharger site in Ventura, CA, with just one slot open [photo: David Noland]](http://images.hgmsites.net/tmb/tesla-model-s-electric-car-road-trip-upstate-new-york-to-southern-california-photo-david-noland_100500011_t.gif)
For years, electric-car skeptics raised concerns about what was cleverly dubbed "The Coal Tailpipe": the idea that plug-in vehicles produced just as many harmful emissions as gasoline cars, but in a different place. That's not remotely true for carbon dioxide, as multiple studies over the years have shown, though it is in limited cases for a small... 
The future of energy production remains in considerable debate, but some new research provides a more optimistic view for a lower-carbon future. Sources for new and replacement energy production remain uncertain, especially the degree to which renewable sources can replace those based on fossil fuels. Even with the newer, optimistic predictions... ![Donald J.

Shortly after announcing his intention to pull the United States out of the Paris Climate Accord, President Donald Trump declared the final week in June to be "Energy Week." In a later speech, Trump called for an energy revolution in the U.S. and vowed to "unleash American energy" to help the country reach its full potential. However, portions of... 
The best analog to EPA administrator Scott Pruitt's latest action might be for the U.S. Geological Survey to undertake a "scientific critique" of theories that the world is round. After all, numerous authoritative sources over the years have raised doubts that the Earth is not flat. Surely their views deserve to be aired. Late last week, it... 
President Donald Trump has announced his intention to pull the United States from the Paris Climate Pact, but private companies and other entities are taking on the challenge of clean energy themselves. Goldwind Americas, a subsidiary of a leading Chinese wind-turbine manufacturer, continues to expand in the United States and it has eyed Wyoming... 
During President Donald J. Trump's half-hour meeting with Pope Francis at the Vatican yesterday, the pope gave the president a copy of his 2015 encyclical calling for urgent, drastic cuts in fossil-fuel emissions. It is unclear whether the U.S. president will peruse the document. Back at home, however, his administration is continuing unabated in... ![The White House, Washington, D.C.

While the news headlines on President Donald Trump mostly address potential scandals, his administration has also lagged significantly in appointing top-level officials to run government agencies. Those that have been appointed often have an adversarial relationship to the missions of the agencies they run. Scott Pruitt, for example, is now... 
It is widely accepted in the energy industry that U.S. coal production will fall as a percentage of the total electric grid mix. That has little to do with its high carbon footprint per kilowatt-hour generated; it is largely due to far greater supplies of much cheaper fracked natural gas. It is also widely accepted that renewable energy sources... 
Yesterday, U.S. president Donald J. Trump signed an executive order to begin the process of rolling back pretty much every vestige of U.S. efforts to address climate change. In both his campaigning and since his inauguration, Trump has claimed that his government and its actions focus on creating or bringing back jobs for working-class Americans... 
It crops up in comments from electric-car advocates and clean-energy users fairly regularly. And it goes something like this: "Big Oil and Gas are on the verge of collapse, as clean energy and electric cars make them obsolete." Occasionally the sentiment is followed by an approving emoji. DON'T MISS: Electric cars pose little threat to oil demand... 
Since the election of Donald Trump, considerable attention has focused on how a candidate who campaigned on promoting fossil fuels would treat the Environmental Protection Agency and other federal agencies charged with regulating those industries. But potential changes to the EPA do not come solely from the Executive Branch. Over the past few... 
As the old saying goes: the enemy of my enemy is my friend. The biofuel and fossil-fuel lobbies have argued in the past over the blending of biofuels with the general fuel supply. But now the two groups have found something they can agree on. DON'T MISS: Sierra Club to sue EPA over failure to report on ethanol A U.S. biofuel-lobbying group is... 
Substantial growth in U.S. renewable-energy capacity will undoubtedly have a positive environmental impact. But the reduction in carbon emissions renewable-energy advocates aim to achieve does not exclude potential benefits to consumers. Because as renewable-energy generating capacity has expanded significantly over the last decade, household...
