Zero eliminates diesel engines entirely, replacing them with an all-electric power and propulsion system with a DC grid at its core, and photovoltaic-thermal panels that capture the light and heat of solar energy.

"A stellarator is a thing that is objectively very difficult to design, objectively very difficult to build, but if it works, it can control the burning hot plasma better than a tokamak."

Burning gas and propane for cooking, water heating and space heating in California homes and businesses creates 10% of the state's greenhouse gas emissions. It also releases pollutants indoors.

"We were considering multiple forms of capital when we started. It just felt like the opportunity is so large that venture capital gives us the opportunity to take those risks upfront and have the possibility to generate an outsized return."

If the lake level drops below 3,490 feet - termed the minimum power pool - the turbines that generate electricity have to be shut down. When the water level reaches critically low thresholds, air is sucked down like a whirlpool into the penstocks, forming explosive bubbles which can cause massive failure inside the dam.

Proper appreciation of the Hoover Dam's man-made majesty requires understanding not just its vital function but also the enormous task of its construction.

Aquaponics systems utilize one gallon of water to produce a kilogram of leafy greens, compared to over 30 gallons in traditional farming, showcasing remarkable efficiency.

Hoppers, like Pixar's pre-Disney films, is a delight. The beavers' world is immersive and richly realized, grounded in science but never dry. The plot zigs and zags between moments of absurdity and emotional heft to stirring effect; I cried multiple times, and not just because of the low-hanging fruit of grandma death.

Most water filter pitchers are made of BPA-free plastic. But as new research shows that bottled-water drinkers ingest tens of thousands of excess microplastic particles, wellness lovers have begun to look askance at water filters that are themselves made of plastic.

The city has rebuilt large stretches of East River Park and raised portions of the shoreline to blunt storm surges and future sea-level rise. The elevated terrain now does double duty as public playground and flood barrier, with new courts, lawns and pathways taking over much of the old footprint.

The pioneering technology means one of the oldest forms of energy storage, hydropower, can be used to store and release renewable energy using even gentle slopes rather than the steep dam walls and mountains that are usually required. The design means the principles of hydropower could be used as a form of long duration energy storage in many more locations across the UK, and the world, than traditional hydropower dams. The projects could be quicker and cheaper to build too.

The proposed 1.5 million acre-foot Sites Reservoir would store water from the Sacramento River and distribute it during droughts to several parts of California, including the Sacramento and San Joaquin valleys, Southern California and the Bay Area. Stretching about 4 miles across and 13 miles north to south, it's meant to provide water to approximately 24 million people, and it would mark California's first major reservoir project since 1979, when New Melones Lake was completed.

Along coastlines, where tides are typically magnified, they profoundly affect navigation, commerce, coastal flooding, water properties and sediment transport. Tides impact the flooding of rivers and, thus, influence the extent of their floodplain, which has cascading effects on biogeochemical and ecological processes.

They're special on a world stage, 85% of chalk streams are in England. They're wonderful habitats, they're great for people as well, people really enjoy them, whether it's areas like this where you can find kingfishers and grey wagtails and it's just a unique resource that we really should steward properly.

Western water law is based on the prior appropriation doctrine, which gives the first entity to make "beneficial use" of water the right to keep on using that amount, even if that means that upstream "junior" users' spigots will get shut off. By the early 1900s, a rapidly growing California was enthusiastically diverting the Colorado River, with huge irrigation districts gobbling up the senior water rights.

When Specian dug into the data, he discovered that implementing energy-efficiency measures and shifting electricity usage to lower-demand times are two of the fastest and cheapest ways of meeting growing thirst for electricity. These moves could help meet much, if not all, of the nation's projected load growth. Moreover, they would cost only half-or less-what building out new infrastructure would, while avoiding the emissions those operations would bring.

At the center of the dispute are eight dams and reservoirs on the Columbia and Snake Rivers in the Pacific north-west that have created devastating obstacles for salmon and steelhead unable to breach their deadly turbines or navigate through the large, warm, artificial pools.

The question of how to protect fish and the ecological health of rivers that feed California's largest estuary is generating heated debate in a series of hearings in Sacramento, as state officials try to gain support for a plan that has been years in the making. "I am passionate that this is the pathway to recover fish," said state Natural Resources Secretary Wade Crowfoot. "This is the paradigm we need: collaborative, adaptive management versus conflict and litigation."
