• Tidal Stream Power Can Significantly Enhance Energy Security

    A new study reveals the potential of tidal resources to make a marked difference on a community’s clean energy ambitions. Using tidal technologies as part of a renewable energy mix can also reduce the space required for power-generating facilities, both on land and at sea, by around 33% and significantly reduce their visual impact since much of their operation is below the sea’s surface.

  • Floods, Rising Sea Levels Push Planned Internal Migration

    Climate change could force billions to move by the end of the century, displaced by floods and rising sea levels. Some communities are already adapting through managed retreat and moving people to other areas.

  • Earthquake Footage Shows Turkey’s Buildings Collapsing Like Pancakes. An Expert Explains Why

    Many of the collapsed buildings appear to have been built from concrete without adequate seismic reinforcement. Seismic building codes in this region suggest these buildings should be able to sustain strong earthquakes (where the ground accelerates by 30% to 40% of the normal gravity) without incurring this type of complete failure. The 7.8 and 7.5 earthquakes appear to have caused shaking in the range of 20 to 50% of gravity. A proportion of these buildings thus failed at shaking intensities lower than the “design code.”

  • Gauging Losses and Lessons in Turkey's Unfolding Earthquake Calamity

    As earthquake engineers stress, most of the time, buildings kill people, not the shaking itself. Many of the buildings destroyed in the quake had “soft floors” – ground-level retail spaces with very little reinforcement supporting far heavier residential floors above; buildings where, for tax purposes, higher floors jutted out beyond the dimensions of the ground floor; or homes where floors were added as families expanded. Engineers call such structures “rubble in waiting.”

  • New Sodium, Aluminum Battery Aims to Integrate Renewables for Grid Resiliency

    A new battery design could help ease integration of renewable energy into the nation’s electrical grid at lower cost, using Earth-abundant metals.

  • Powering the Nation: How to Fix the Transformer Shortage

    America’s electric grid relies on transformers — electrical components that convert voltage, enabling power distribution to homes and businesses. Disruptions to transformer operations, such as natural disasters, extreme weather, or cyber/physical attacks, cause substantial economic damage. Securing the transformer supply chain is critical to ensure resilience, expand renewable power, and strengthen grid safety. To mitigate potential disruptions, Congress should spur the supply of transformers by investing in domestic transformer manufacturing and workforce development.

  • Supporting Dams with Innovative Materials

    There are about 91,000 dams in the United States. About half the dams built in the past century and a half are starting to show their age, with resulting wear and tear. Severe weather events, extreme temperatures, erosion and rising water levels are all straining the infrastructure and exacerbating the impacts of deterioration and aging processes. In many cases, simply replacing the dams and levees is not a viable option due to high costs.

  • Extremist Couple Charged in Plot to Destroy Baltimore’s Power Grid

    Two extremists have been charged Monday with conspiracy to attack and destroy energy facilities around Baltimore in a plot to “completely destroy” the city. The man, the founder of the neo-Nazi group Atomwaffen, and his accomplice appear to be part of trend among domestic violent extremists to target the U.S. electrical grid. In recent years, DHS and the FBI have discovered several such conspiracies to take down the power system, with the most recent attacks taking place in North Carolina and Washington State.

  • Climate Change-Driven Water Crises More Severe Than Previously Thought

    The interference of climate change with the planet’s water cycle is a well established fact. New analyses suggest that in many places, runoff responds more sensitively than previously assumed.

  • Creating Buildings That Can Withstand the Most Extreme Stress Loads

    Combined ballistic impacts pose a major challenge for engineers who build structures that must withstand extreme stresses. An explosion can hurtle fragments and debris at enormous velocities so they strike the surroundings. Then comes the shock wave. It’s a scary combination.

  • Western Wildfires Destroyed 246% More Homes and Buildings Over the Past Decade

    It can be tempting to think that the recent wildfire disasters in communities across the West were unlucky, one-off events, but evidence is accumulating that points to a trend. In nearly every Western state, more homes and buildings were destroyed by wildfire over the past decade than the decade before, revealing increasing vulnerability to wildfire disasters.

  • There’s a Deal to Save the Colorado River — If California Doesn’t Blow It Up

    After months of tense negotiation, a half-dozen states have reached an agreement to drastically cut their water usage and stabilize the drought-stricken Colorado River — as long as California doesn’t blow up the deal. The plan would cut water use on the river by roughly a quarter, drying up farms and subdivisions across the Southwest.

  • Grant to Support High-Potential Computer Science Students

    The University of Texas at El Paso received a $5 million grant from the National Science Foundation (NSF) to provide financial support and professional development experiences to talented students in the field of computer science.

  • Restoring Power to the Grid

    Computer scientists have been working on an innovative computer model to help grid operators quickly restore power to the electric grid after a complete disruption, a process called a black start.

  • Illuminating the Barrier to Next-Generation Battery That Charges Very Quickly

    In the race for fast-charging, energy-dense lithium metal batteries, researchers discovered why the promising solid electrolyte version has not performed as hoped. This could help new designs – and eventually battery production – avoid the problem.
