• What Does It Mean to Be Energy Independent?

    “‘Energy independence’ is a political slogan, not an economic or technical concept with a clear definition,” Berkeley’s Andrew Campbell says. “I understand that politicians use the term ‘energy independence’ to imply that a country is insulated from global energy markets. However, this is rarely the case.”

  • Can Germany Wean Itself Off Russian Gas?

    Experts are divided on how quickly Germany could cut imports of Russian energy and stop funding President Vladimir Putin’s invasion of Ukraine. How vulnerable would such a move leave Europe’s largest economy?

  • The Ukrainian Economy: Where Now for the Future?

    An expert has warned that the impact of the war will be disastrous for the Ukrainian economy, regardless of the outcome. “War will always have a catastrophic impact. As you’d expect, production is collapsing, and the economy has given up percentages of GDP growth,” says a Cambridge University professor who is an economic adviser to Ukrainian President Zelensky.

  • Pivotal Battery Discovery Could Benefit Transportation, the Grid

    Researchers uncover new avenue for overcoming the performance decline that occurs with repeated charge-discharge cycling in the cathodes of next generation batteries.

  • Coastal Home Buyers Are Ignoring Rising Flood Risks, Despite Clear Warnings and Rising Insurance Premiums

    Homebuyers along the U.S. coasts can check each property’s flood risk as easily as they check the size of the bedrooms – most coastal real estate listings now include future flood risk details that take climate change into account. In Apollo Beach, for example, many of the properties are at least 9 out of 10 on the flood risk scale. That knowledge isn’t stopping homebuyers, though.

  • Predicting, Managing EV Charging Growth to Keep Electricity Grids Reliable, Affordable

    With a growing fleet of EVs on the road, grid planners depend on accurate estimates of charging patterns to calculate electricity demand. A team of researchers at Stanford University assembled a scalable probabilistic model for charging demand that can be applied to a flexible array of populations and account for a wide range of factors.

  • Targeted demand response reduces price volatility of electric grid

    To reduce the energy load during supply constraints on the Texas power grid, it is not necessary to reduce the energy load in high population centers such as Houston and Dallas. Instead, when supply is strained, focusing on a few strategic locations across the state outside of those high-population areas is much more cost-effective and can have a greater impact on the price volatility of the grid.

  • Groundwater Levels Fall Across Western and Central Kansas

    Average groundwater levels across western and central Kansas fell by more than a foot in 2021, with the greatest declines in the southwest portion of the state. “The entire state is currently in some stage of drought and even with recent snowfalls, I bet it remains that way,” one expert said.

  • Green Rare-Earth Recycling Goes Commercial

    Rare earths are essential ingredients in the magnets that power many technologies people rely on today, such as cell phones, computers, electric vehicles, and wind turbines. Researchers have  developed a novel way to extract rare earth elements (rare earths) from the high-powered magnets in electronic waste (e-waste).

  • Ultrafast Devices to Protecting the Grid from EMPs

    Scientists from Sandia National Laboratories have announced a tiny, electronic device that can shunt excess electricity within a few billionths of a second while operating at a record-breaking 6,400 volts — a significant step towards protecting the nation’s electric grid from an electromagnetic pulse.

  • Could Nuclear Power Cut Europe’s Dependence on Russian Energy?

    The war in Ukraine has set off a rush in Europe to find alternatives to Russian oil and gas. Some are calling for an expansion of nuclear power.

  • Texas Cold Snap Highlights Need for Improved Power Systems

    The greatest demand for electricity in Texas is traditionally during the hottest days of the year, when air conditioners turn on full blast to beat the heat. But in February 2021, an unusually long spell of cold weather took the region by surprise. With extreme weather events rising in frequency, the need for a prepared modern energy grid grows.

  • Texas Warns Firms They Could Lose State Contracts for Divesting from Fossil Fuels

    A new law prohibits the state from contracting with or investing in companies that divest from oil, natural gas and coal companies.

  • As Sea Levels Rise, Coastal Megacities Will Need More Than Flood Barriers

    Sea level rise is expected to worsen in the next few decades, especially for many of the world’s largest cities in lower and middle income countries of Africa, Asia and Latin America. These cities are already improving their infrastructure. But most of the focus remains on big engineering solutions (like flood walls and embankments) rather than a more holistic plans.

  • Electric Truck Hydropower: Flexible Solution to Hydropower in Mountainous Regions

    Mountain regions have a large potential for hydropower that cannot be harnessed effectively by conventional technologies. Researchers developed an innovative hydropower technology based on electric trucks that could provide a flexible and clean solution for electricity generation in mountainous regions.
