Nuclear power provides 60 percent of US carbon-free electricity generation, but existing plants are aging and only one is under construction. Should government intervene to keep nuclear energy in the mix?

Energy Secretary Rick Perry says the US needs to subsidize nuclear and coal power plants to keep the grid stable. But this policy would raise energy costs and could drive consumers off-grid instead.
The imposition of steep duties on imported solar panel components could jeopardize thousands of jobs in the industry.
A trade spat could jack up the cost of going solar, killing jobs and obstructing efforts to do something about climate change.

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.

Coal-fired power plants produce air pollution that kills thousands of Americans every year. President Trump's embrace of coal energy will delay a shift to cleaner fuels that is saving money and lives.
When it comes to TV use energy, calling one household ‘average’ can be misleading.

People who watch a lot of TV consume a disproportionate amount of electricity so we should tailor energy efficiency incentive programs to these and other big energy users.
Energy network owners are frequently using legal battles to draw out the regulatory process.
Generators, retailers and consumers should be central to regulating utilities because network operators are gaming the system.
Solar power in suburbia: what’s not to like?
Utilities are pushing back against the spread of rooftop solar power and charging bigger fees to solar homes. Who is right in this solar-versus-utilities fight?
Supreme Court ruling allows consumers and businesses to make money by reducing power and other grid services.
An obscure Supreme Court ruling paves the way for people and businesses to earn money with distributed energy technologies.
Rooftop solar panels: will they kill power companies or can they help them?
Many utilities see rooftop solar as a threat, but solar power can actually lower the cost of power they – and their consumers – need to pay during hours of high demand.
Now regulated for carbon emissions.
How the US ended up regulating carbon emissions using the 1970 Clean Air Act rather than a national cap-and-trade emissions trading system.
Lots of wind blowing – often at night when there’s little demand for power.
Smoothing out variable wind and solar is a growing problem. Instead of storing energy with batteries, utilities can adjust the power of millions of devices in buildings and homes.
With rooftop solar installations soaring, utilities are nervous – for a few reasons.
Electric utilities want to quash distributed solar because they don't want the competition, right? Perhaps, but if you rely at all on the grid, you have a stake in this fight, too.
