The Facts Behind Hydropower
Hydropower accounts for nearly 7% of all electricity generated in the United States and provides quick-start capabilities during blackouts and the ability to store power for high-demand periods. ORNL’s HydroSource provides updated information on hydropower facilities and infrastructure, models and visualizations for future development, and analytical tools to better understand how and where hydropower can be implemented throughout the U.S.

Reviving the Petroleum Administration for War: A Case for Government-Industry Partnership
The Russo-Ukrainian War is exposing deep fissures in global energy networks and finally forcing Western capitals to address their energy security. Ryan P. Kellogg and David Brunnert write that “To confront this profound challenge, policy should consider creating a partnership between government and industry for managing energy resources.”

Climate Change Is Making Flooding Worse: 3 Reasons the World Is Seeing More Record-Breaking Deluges and Flash Floods
Although floods are a natural occurrence, human-caused climate change is making severe flooding events more common. I study how climate change affects hydrology and flooding. In mountainous regions, three effects of climate change in particular are creating higher flood risks: more intense precipitation, shifting snow, and rain patterns and the effects of wildfires on the landscape.

Using Historical Weather Data to Optimize Power Grid
With the record-breaking heat and drought conditions states across the U.S. are currently facing, finding a solution to the growing need for reliable power from the electric grid is at an all-time high. Information about past outlier conditions could provide valuable context to help operators better manage the grid during extreme weather.

A Water Strategy for the Parched West: Have Cities Pay Farmers to Install More Efficient Irrigation Systems
Unsustainable water practices, drought and climate change are causing this crisis across the U.S. Southwest. To achieve a meaningful reduction in water use, states need to focus on the region’s biggest water user: agriculture.

Europe’s Energy Choice
Russia’s war in Ukraine and the disruption of Russian gas exports to Europe has triggered an energy crunch, with price spikes unlike anything seen since 1973. And the situation will get worse before it gets better. Responding to the immediate energy crisis in the right way will help to address the broader climate challenge. Authorities must both buffer the shock of the gas crunch in the short term, and accelerate the transition to clean energy in the long -term.

New Flood Maps Clarify the Risk Homeowners Face
Flooding in urban areas cost Americans more than $106 billion between 1960 and 2016, damaging property, disrupting businesses and claiming lives in the process. Determining which areas are most likely to flood amid ever-changing land use and shifting rainfall and climate patterns can be expensive and complicated. New maps more realistically depict flood zones with less effort, lower costs.

The World’s Largest Experimental Earthquake Infrastructure Facility
The National Science Foundation (NSF) promotes research investments and technology that help recognize and mitigate the impacts of natural disasters across the U.S.“The ability to test infrastructure under a full range of motion is critical for unleashing new and pioneering research that can lead to effective, economical and innovative infrastructure designs and retrofitting strategies for existing infrastructure,” said NSF director Sethuraman Panchanathan.

Why UK Railways Can’t Deal with Heatwaves – and What Might Help
Like most construction materials, steel, which rails are made from, expands when air temperature increases. When this movement is restrained by the anchorage, which holds the rail and the sleeper (the rectangular supports for the rails) in place, internal stresses build up, and compression buckles or kinks the rail. Trains cannot travel over rail lines with kinks. In the US, kinks caused by the sun caused over 2,100 train derailments in the past 40 years, equivalent to around 50 derailments per year.

Climate Change, Land-Use Changes Increase Likelihood of Flood Events
The German government estimates the total losses resulting from the disastrous floods in July 2021 at 32 billion euros. To improve future preparedness for such extreme events, researchers advise that risk assessments take greater account of the landscape and river courses, how they change, and how sediments are transported. In addition, projections show an increase in the spatial extent and frequency of such extreme events, as well as higher amounts of precipitation.

Generating Power at the Point Where Seawater, River Water Meet
It is theoretically possible to generate electricity through the movement of water in locations where seawater and river water meet. This type of technology is called osmotic power generation or blue energy. Though prototypes of this technology have been built, research is still underway to prove that this technology is scalable and reliable.

Water Wars: A Historic Agreement Between Mexico and US Is Ramping Up Border Tension
As climate change drives rising temperatures and changes in rainfall, Mexico and the US are in the middle of a conflict over water, putting an additional strain on their relationship. Partly due to constant droughts, Mexico has struggled to maintain its water deliveries for much of the last 25 years, deliveries to which it is obligated by a 1944 water-sharing agreement between the two countries.
