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.

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.

In Puerto Rico the Trump administration's 'energy dominance' policy echoes colonial practices by fast-forwarding fossil fuel projects over community resistance.
Having an antagonistic debate over climate change will not shed any more light on the fundamentals of climate science.
Why assembling two teams to debate climate change is all about political spectacle and sowing doubt – and has nothing to do with actual climate science.
After spending $9 billion on a nuclear power plant construction in South Carolina, project developers have pulled the plug.
Nuclear power plants don't just pump out steady, carbon-free electricity; they also help produce the people the US needs for nuclear weapons inspections.

When utilities plan investments, they think decades ahead. A recent study shows why power companies should be spending more on renewables despite the Trump administration's tilt toward fossil fuels.
The surge in U.S. oil and natural gas production has transformed the energy picture in the country, but the influence is muted globally.
The Trump administration has set a new national policy: energy dominance. But can the US really dominate other countries through fossil fuel exports?
You may agree the U.S. should move to renewables, but how quickly can we do it and how?
How fast can the US transition to clean energy and with what energy sources? Here's why an impassioned debate among energy wonks matters to the rest of us.
