• Cybersecurity Goes Undercover to Protect Electric-Grid Data

    Researchers, inspired by one of the mysteries of human perception, invented a new way to hide sensitive electric grid information from cyberattack: Within a constantly changing color palette.

  • U.S. Should Begin Laying the Foundation for New and Advanced Nuclear Reactors: Report

    New and advanced types of nuclear reactors could play an important role in helping the U.S. meet its long-term climate goals, but a range of technical, regulatory, economic, and societal challenges must first be overcome.

  • Geothermal Energy: Limitless, Renewable, and Nonpolluting

    Geothermal resources offer a tantalizing opportunity to provide affordable, carbon-neutral electricity. It is virtually limitless, “always on,” and widely available across all fifty states.

  • The Critical Minerals End-Game?

    To reduce greenhouse gas emissions, there’s been a dramatic uptake of renewable energy, primarily solar and wind, with a transition to lithium-ion batteries for electric vehicles and energy storage. The transition relies on increasing the extraction of critical minerals for their production.

  • Enhancing Advanced Nuclear Reactor Analysis

    Nuclear power is a significant source of steady carbon-neutral electricity, and advanced reactors can add more of it to the U.S. grid, which is vital for the environment and economy. Sandia Lab researchers have developed a standardized screening method to determine the most important radioactive isotopes that could leave an advanced reactor site in the unlikely event of an accident.

  • Shutting Down Nuclear Power Could Increase Air Pollution

    Nearly 20 percent of today’s electricity in the United States comes from nuclear power. The U.S. has the largest nuclear fleet in the world, with 92 reactors scattered around the country. Many of these power plants have run for more than half a century and are approaching the end of their expected lifetimes. If reactors are retired, polluting energy sources that fill the gap could cause more than 5,000 premature deaths, researchers estimate.

  • Deadly Lessons from Fukushima Changed Japan and the World

    The strongest earthquake in Japan’s recorded history triggered a massive tsunami in 2011. Together, the two natural disasters claimed close to 20,000 lives, making the event one of the deadliest in Japan’s history. But the crisis didn’t end there.

  • Colorado River Water Plan Could Trigger Unprecedented Supply Cuts, Ripple Effects on Key Industries

    Decades of drought and overuse have brought the river’s water levels to historic lows. States in the Lower Colorado River Basin — Arizona, California and Nevada — now must choose between one of three options proposed by the federal government. The economic impact of the river’s dwindling water supplies is could be disastrous.

  • Germany: Seeking Solution for Remaining Nuclear Waste

    Nuclear energy in Germany has been history since mid-April. The last three nuclear power plants ended their operations on April 15. Germany’s nuclear power might be gone, but nuclear waste isn’t going anywhere. The search for a location for a final repository remains a challenge.

  • Forced Water-Use Cuts Made California More Waterwise

    After a drought-stricken California lifted a year of mandatory water-use cuts that were effective in 2015 and 2016, urban water use crept back up somewhat, but the overall lasting effect was a more waterwise Golden State.

  • Progress in Alternative Battery Technology

    It is not easy to make batteries cheap, efficient, durable, safe and environmentally friendly at the same time. Researchers have now succeeded in uniting all of these characteristics in zinc metal batteries. Zinc batteries are considered a possible future alternative to the lithium-ion batteries now widely in use. Currently, however, their use often requires toxic salts.

  • AI Can Predict Electricity Grid Loads from Road and Rail Usage Data

    To satisfy demand and manage consumption peaks, electricity suppliers have to be able to predict grid loads. Researchers havedeveloped an artificial intelligence system capable of accurately anticipating grid loads from road and rail traffic data.

  • Two Men Sentenced in Plot to Attack Power Grids in the United States

    Two men were sentenced in federal court Friday, 21 April, for crimes related to a scheme to attack power grids in the United States in furtherance of racially or ethnically motivated violent extremism. DHS and the FBI have warned that domestic terrorists were increasingly focused on disrupting the U.S. power grid.

  • Cities Will Need More Resilient Electricity Networks to Cope with Extreme Weather

    Dense urban areas amplify the effects of higher temperatures, due to the phenomenon of heat islands in cities. This makes cities more vulnerable to extreme climate events. Large investments in the electricity network will be necessary to cool us down during heatwaves and keep us warm during cold snaps.

  • As States Replace Lead Pipes, Plastic Alternatives Could Bring New Risks

    Across the country, states and cities are replacing lead pipes to address concerns over lead-contaminated drinking water, an urgent health threat. But critics say that substituting PVC for lead pipes “may well be leaping from the frying pan into the fire.”
