How bad are things for U.S. coal? Very bad, but that's very good for environment. Now the question is whether other countries will cut back on coal as well.
A former state regulator and member of the U.S. Nuclear Regulatory Commission argues that subsidizing reactors to keep them running is unnecessary and will be bad for consumers and the environment.
A nuclear engineer makes the case that nuclear power plants are important resources and should receive economic rewards for providing steady supplies of carbon-free electricity.
The anti-nuclear movement in the U.S. is at a critical juncture as worries over climate change grow.
Can nuclear power plants like California Diablo Canyon be replaced without greatly raising emissions? It's an open question.
Women are underrepresented in the energy sector at a time of rapid change and demand for new talent. Hiring more women could make energy companies more innovative and speed the shift to clean fuels.
Making expanded fossil fuel production the core of U.S. energy policy, as proposed by Donald Trump, and backing out of climate agreements would cost the U.S. economy billions and transform the planet.
The boom in oil and gas development has brought new revenues to many communities in the U.S., but rural areas in particular have struggled to handle the rapid downturn in prices.
It's not just energy-hungry pot farms: the ties between energy and drugs run deep. Can we develop a national drug policy drawing on the lessons of the domestic oil and gas boom?
The next president will have little power to slow the growth of renewable energy, sliding oil prices or coal's decline.
The U.S. energy system is gradually transitioning away from fossil fuels and toward renewables. Will the next president speed up America's shift to renewable energy or step on the brakes?
Even before the death of Justice Antonin Scalia, the Supreme Court’s stay placed the fate of the EPA Clean Power Plan into the hands of the next president.

Ted Cruz opposes subsidies for biofuels and still managed to win in ethanol-friendly Iowa. Is corn ethanol starting to lose its political clout?
The wind and solar industries scored a huge win by getting extended tax credits, but research shows this isn't the best policy for lowering emissions through renewable energy.
Study shows that many of the utility-scale solar power plants in California have been placed near protected and environmentally sensitive lands.
After all the jubilation about the president's plan, it's time for a reality check.
Poor Americans suffer disproportionately from higher energy prices. Energy policies should fund innovation to make low-carbon energy cheaper.
