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.

The anti-nuclear movement in the U.S. is at a critical juncture as worries over climate change grow.
Rwanda has adopted a number of plans to improve its electricity output. There are valuable lessons other African countries can learn from it.
When will residential solar be cheaper than the cost of power from the grid? This point of ‘grid parity’ is a moving target but moving closer in a number of places.
If you’re worried about rising electricity prices, then going off-grid sounds attractive. But why not create an intelligent network of solar-powerd batteries that can reduce prices for all?
An obscure Supreme Court ruling paves the way for people and businesses to earn money with distributed energy technologies.
The U.S. could dramatically increase solar and wind power without expensive energy storage. The key is to overlay high-voltage direct current power lines on our system of regional grids.
Malware has brought down the power grid in the Ukraine. What were attackers after and could it happen elsewhere?
New Canadian prime minister Justin Trudeau brings a very different face to climate talks in Paris. Will it project its oil extraction tradition or show global leadership on emissions cuts?
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.
The Supreme Court hears a case that will decide whether homes and businesses can earn money from distributed energy technologies, including demand response and home battery systems.
When Facebook goes down it’s an irritation. But as the world moves its data and processing to the cloud, the potential for major loss grows ever greater.
Our power grid infrastructure on Earth is more vulnerable to space weather than previously thought – with susceptibility in more regions and even during quiet geomagnetic periods.
Despite looming legal challenges, states are devising plans to comply with limits on power plant carbon emissions – a crucial part of Obama’s climate policies.
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.
The internet of things – including the equipment on the power grid – is increasing cybersecurity risks for all critical infrastructure.
As it’s done with its electric cars, Tesla will need to rely on well-heeled early technology adopters and friendly regulations to sell lots of home batteries.
Batteries combined with digital technologies will improve the efficiency and reliability of the electric grid, transforming how people use their energy.
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.
