Feds Ease Up on Colorado River Restrictions — for Now
The water shortage crisis on the Colorado River is improving, but it’s far from over. The water levels in the river’s two main reservoirs have begun to stabilize, lessening the need for states in the Southwest to cut their water usage. This year’s wet winter helped save the river from collapse, but a reckoning is on the horizon.

Training Students to Succeed in the “Fourth Industrial Revolution”
Transformational changes are already underway in the manufacturing industry as technological advancements, such as artificial intelligence (AI) and smart devices from the “fourth industrial revolution” or Industry 4.0., inspire a digital-first approach to engineering. University of Missouri researchers are using a $1 million grant to support the development of an Industry 4.0 lab, training engineering students for the future of digitization in manufacturing.

NREL Analysis Reveals Benefits of Hydropower for Grid-Scale Energy Storage
Closed-loop pumped storage hydropower systems rank as having the lowest potential to add to the problem of global warming for energy storage when accounting for the full impacts of materials and construction, according to new analysis. These systems rely on water flowing between two reservoirs to generate and store power.

How the Caribbean Is Building Climate Resilience
Small island nations in the Caribbean are among the countries in the world most vulnerable to the effects of climate change, including rising sea levels, coastal erosion, and stronger and more frequent storms. Governments in the region are taking steps to combat it, but climate finance remains a challenge as Caribbean nations struggle with heavy debt burdens, despite receiving some regional and international support.

We Could Soon Be Getting Energy from Solar Power Harvested in Space
The idea of space-based solar power (SBSP) – using satellites to collect energy from the sun and “beam” it to collection points on Earth – has been around since at least the late 1960s. Despite its huge potential, the concept has not gained sufficient traction due to cost and technological hurdles. space-based solar power is technologically feasible, but to be economically viable, it requires large-scale engineering, and therefore long-term and decisive commitment from governments and space agencies.

Tech Breakthrough Could Increase States’ Use of Geothermal Power
Lawmakers in some states have been laying the groundwork to add geothermal power to the electrical grid and pump underground heat into buildings. Now, a technological breakthrough could dramatically expand those ambitions — and perhaps unleash a new wave of policies to tap into geothermal sources. If the technology’s promise is fulfilled, geothermal could power as much as 20% of the U.S. grid.

FEMA Maps Said They Weren’t in a Flood Zone. Then Came the Rain.
The most common reference for flood risk are the flood insurance rate maps, also known as 100-year floodplain maps, that the Federal Emergency Management Agency, or FEMA, produces. They designate so-called special flood hazard areas that have a roughly 1 percent chance of inundation in any given year. Properties within those zones are subject to more stringent building codes and regulations that, among other things, require anyone with a government-backed mortgage to carry flood insurance. Flaws in federal flood maps leave millions unprepared. Some are trying to fix that.

Beaver-Like Dams Can Enhance Existing Flood Management Strategies for At-risk Communities
River barriers made up of natural materials like trees, branches, logs and leaves can reduce flooding in at-risk communities. Leaky barriers are effective in slowing down the flow of the river during periods of rainfall and storing up vast quantities of water which would otherwise rush through causing damage to communities downstream.

Reached: Milestone in Power Grid Optimization on World’s First Exascale Supercomputer
Ensuring the nation’s electrical power grid can function with limited disruptions in the event of a natural disaster, catastrophic weather or a manmade attack is a key national security challenge. Compounding the challenge of grid management is the increasing amount of renewable energy sources such as solar and wind that are continually added to the grid, and the fact that solar panels and other means of distributed power generation are hidden to grid operators.

“Hacking” People, Not Systems: False Claims Attacks on Infrastructure
False claims and disinformation, especially in a social media-driven society, have become major problems with potentially severe consequences. Disinformation can be weaponized to disrupt underlying cyber-physical systems, human lives and economic productivity. Recent examples include tweets that trigger spikes in gasoline prices and false social media posts reporting impending water pumping station shutdowns. In these scenarios, chaos is caused because people, not systems or devices, are “hacked.”

Urban Street Networks and Building Density Shape Severity of Floods
Cities around the globe are experiencing increased flooding due to the compounding effects of stronger storms in a warming climate and urban growth. Researchers’ new analytical model can assess neighborhood-level hazards globally.
Could We Use Volcanoes to Make Electricity?
It is challenging, but tapping into the Earth’s natural heat can create a renewable, reliable and clean source of energy. As technology improves, more places around the world will turn to geothermal energy to light up people’s lives. Volcanoes are reminders of a great powerhouse deep underground that’s waiting to be harnessed.
To Get Off Fossil fuels, America Is Going to Need a Lot More Electricians
To cut greenhouse gas emissions on pace with the best available science, the United States must prepare for a monumental increase in electricity use. Burning fossil fuels to heat homes and get around isn’t compatible with keeping the planet at a livable temperature. Appliances that can be powered by clean electricity already exist to meet all of these needs. The problem is, most houses aren’t wired to handle the load from electric heating, cooking, and clothes dryers, along with solar panels and vehicle chargers. And a shortage of skilled labor could derail efforts to “electrify everything.”
