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.

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.

In many Texas households, outdoor watering accounts for more than half of the total summer water use. The biggest mistake people make is watering in the middle of the afternoon. When the sun is at its peak, a significant percentage of that water evaporates before it ever hits the roots of your St. Augustine or Bermuda grass.

The first step to sustainability is seeing that there is no boundary between you and nature. When we see this essential connection and reverse the artificial disconnections created over millennia, people can imagine a future where we all thrive with a regenerated ecosystem.

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 Iran war has once again shown our drive for clean power is essential for our energy security so we can escape the grip of fossil fuel markets we don't control.

The UC Berkeley Chancellor's Fund, the college's attempt at venture capital, has raised more than $250,000 from a single investor. Chancellor Rich Lyons has said he wants to blur the edge between the university and the region's startup ecosystem.

The ground beneath our feet holds so much energy that experts at the Department of Energy think geothermal power could generate 60 gigawatts - or nearly 10% of U.S. electricity - by 2050. Zanskar co-founder and CEO Carl Holland thinks that lofty number is too low, mostly because it's discounting conventional geothermal's potential. The DOE's figures assume advances in enhanced geothermal, which uses fracking techniques to access hot rock deep underground.

Fusion power promises to supply the world with large amounts of clean heat and electricity, if researchers and engineers can solve some vexing challenges. At its core, fusion power seeks to harness the power of the Sun. To do that, fusion startups must figure out how to heat and compress plasma for long enough that atoms inside the mix fuse, releasing energy in the process.

A pair of former Dyson engineers have raised millions of pounds to bring a battery-powered electric boiler to market, positioning it as a lower-cost, lower-disruption alternative to heat pumps for millions of UK homes. Wiltshire-based Luthmore was founded in 2022 by Craig Wilkinson and Martin Gutkowski, both ex-Dyson engineers who previously worked together on projects including the vacuum maker's abandoned electric car programme.

In Indra's Net of pearls and jewels, every gem reflects every other, a shimmering image of interdependence. This ancient Vedic metaphor for connection across the cosmos also illuminates what the environmental philosopher Glenn Albrecht first proposed in 2014as 'theSymbiocene': the era after the Anthropocene, in which human technologies take their cues from living systems and work in partnership rather than through dominance.

Photovoltaic (PV) solar energy represents a modular technology that can be manufactured in large-scale facilities, generating economies of scale, while also being adaptable to small-scale applications. From residential rooftop systems to large-scale power generation installations, photovoltaic solar energy has established itself as a cost-effective option for electricity production in many countries around the world.

An all-electric, energy-efficient alternative to gas-burning furnaces, heat pumps are widely seen as the climate-friendly home heater of choice. They can do double-duty as both home heaters and AC units and are pretty good at maintaining a constant temperature inside a home without the blast-then-cool-off cycle typical of a furnace.

The updated Building Emissions Saving Ordinance (BESO) requires sellers of single family homes or duplexes to complete at least six credits worth of upgrades before final sale or pay $2,500 to the city, which is then funneled to the buyer upon completion of the upgrades. For many sellers, installing a heat pump is the easiest and most efficient way to earn all six credits in one fell swoop, while also significantly increasing the appeal of the property, notes Grimsich, CEO of 1-888-Heat-Pumps.

The pipes channel rainwater into one of three underwater storage tanks, where it is filtered and prepared for recycling within the building.
