Trump speculates on diesel fuel export ban as high prices ripple across US economy

There’s not much diesel fuel lying around, and lots of people want to buy what is available, as well as what little is produced each day. It’s all a matter of supply and demand.

What air pollution does to the human body

The EPA is changing how it assesses proposed regulations by dropping the monetary value of health benefits from its cost-benefit analyses. That misses a big piece of the picture.

Google plans to power a new data center with fossil fuels, yet release almost no emissions – here’s how its carbon capture tech works

To reduce emissions put into the atmosphere, Google is using carbon capture and sequestration. But not all CCS projects are the same.

Industrial pollution once ravaged the Adirondacks − decades of history captured in lake mud track their slow recovery

Acid rain and metals from power plants, vehicles and industries reached remote mountain lakes for years. Evidence from those lakes today shows the success of the Clean Air Act.

Revoking EPA’s endangerment finding – the keystone of US climate policies – isn’t simple and could have unintended consequences

The Trump administration’s goal is to roll back rules limiting planet-warming greenhouse gas emissions from power plants, vehicles and oil and gas production, but it could backfire for industry.

Utilities rely on dirty ‘peaker’ plants when power demand surges, but there are alternatives

As renewables account for a growing share of electricity supply, fossil fuel plants are increasingly used to balance fluctuations in renewable generation – emitting health-threatening pollutants.

What is a virtual power plant? An energy expert explains

Some power plants don’t have massive smokestacks or cooling towers – or even a central site.

EPA’s crackdown on power plant emissions is a big first step – but without strong certification, it will be hard to ensure captured carbon stays put

Fossil fuel power plants can avoid most emissions by capturing carbon dioxide and pumping it underground. But to be a climate solution, that carbon has to stay stored for thousands of years.
