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.

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.

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.

Armored Transformer Barrier Protects Electric Power Grid
A 2013 sniper attack on an electric power substation in Northern California, which caused more than $15 million in damages and destroyed 17 transformers, led researchers to develop a novel protective solution: the Armored Transformer Barrier system.

The long view
Boosting Efforts to Predict Harmful Solar Weather Events
When big blasts of energy from the sun envelop the Earth, they can very strong: a 2015 event so weakened Earth’s protective magnetic field that it penetrated to the atmosphere, posing a threat to everything from circling space station astronauts to delicate electronics and communication systems.
Preparing Communities for Dam-Related Emergencies
There are more than 90,000 dams registered in the U.S. National Inventory of Dams across the country. But we rarely hear about them until the worst happens: one of them fails. Extreme weather events and the aging dam infrastructure are making dam-related emergency action plans more critical than ever.
Challenges to Tidal Flats Pose Risks to 41M Americans Living in Coastal Counties
About 29 percent of the United States’ population live in coastline counties – more than 41 million are in Atlantic counties. This high population density poses a critical challenge to sustainable developments in coastal areas.
Critical Global Water Questions
Recent intense heatwaves in India and widespread U.S. droughts have highlighted the need for a global approach to tackling chronic water shortages. The problem is that most governments are not equipped to deal with these challenges of water scarcity, sanitation and climate dynamics.
Mitigating Flood Disasters
Engineers have proposed a flood control measure which recommends designing permeable pavements to specifically suit local rainfall and soil conditions and reduce flood impacts.
Developing Novel Hybrid Reef-Mimicking Structures
Despite previous efforts to implement storm mitigation solutions — including concrete breakwaters — damage due to storm surge and flooding continues to devastate coastal areas around the world. In response to these threats, DARPA has launched the Reefense program to develop self-healing, hybrid biological, and engineered reef-mimicking structures to protect civilian and DoD infrastructure, personnel by mitigating damage related to coastal flooding, erosion and storm surge.
