May 27, 2025 -Three years ago, Ted Treadwell turned his water heater into a battery.

His home in Santa Rosa, California, had relied on a gas-powered furnace and water heater for a quarter-century to stay warm. But as the equipment neared the end of its life, the retired software engineer wanted something new — and to sever his ties to the gas utility.

May 16, 2025 -It’s well documented that AI is a power-hungry technology. But there has been far less reporting on the extent of that hunger, how much its appetite is set to grow in the coming years, where that power will come from, and who will pay for it. For the past six months, MIT Technology Review’s team of reporters and editors have worked to answer those questions. The result is an unprecedented look at the state of AI’s energy and resource usage, where it is now, where it is headed in the years to come, and why we have to get it right.

May 12, 2025 -The Energy Department said on Monday that it was preparing to roll back energy and water conservation standards for a long list of electric and gas appliances, targeting 47 regulations that it said were “driving up costs and lowering quality of life for the American people.”

The moves follow an executive order last week from President Trump directing the Energy Department to “eliminate restrictive water pressure and efficiency rules that make household appliances less effective and more expensive.”

Apr. 16, 2025 -Nestled in a quiet suburb of Maryland, it’s about 1,500 square feet, with three bedrooms across two floors. In an average year, the family in this home spends around $3,483 on utilities:

All that energy creates around 8.4 metric tons of CO2 emissions per year, or the equivalent of more than eight round-trip transatlantic flights.

Mar. 12, 2025 -There’s a new type of LED in town. These light-emitting diodes (LEDs) are made from a material called perovskite, a calcium titanium oxide mineral that is more closely associated with cheap solar panels. The perovskite LEDs are not only highly efficient and cheap to make but could also be more environmentally friendly than their predecessors.

“Perovskite LEDs are cheaper and easier to manufacture than traditional LEDs, and they can also produce vibrant and intense colours if used in screens. I’d say that this is the next generation of LED technology,” says Feng Gao, professor of optoelectronics at Linköping University.

Jan. 14, 2025 - Idaho Power Company has tapped Prevalon Energy to supply what is slated to be the state of Idaho’s largest battery energy storage system (BESS), a 200 MW/800 MWh project. The BESS would enhance grid resiliency as a net peak solution, helping the utility maintain reliable power during periods of high demand.

It is the second storage deal between the Mitsubishi Power Americas spinout and Idaho’s largest utility, following a similar arrangement for a 328 MWh BESS announced last May.

Dec. 11, 2024 -Avertiginous outcrop with more than 500 volcanoes, El Hierro, the most westerly of the Canary Islands, is less than 12 miles (20km) wide but features elevation differences of more than 1,500 metres. Swept by strong Atlantic winds and pockmarked with volcanic craters, it has spent the past decade harnessing its natural features to create clean electricity – with the goal of being the first island to reach self-sufficiency in energy.

Dec. 10, 2024 -Electric heat pumps, the most affordable and energy efficient way to heat and cool homes, continue to outsell gas furnaces nationwide. They can also reduce outdoor pollution and, as a result, save lives, according to a report issued on Tuesday.

The study, by , a nonprofit group that promotes electrification, calculated that if every American household got rid of furnaces, hot water heaters and clothes dryers powered by oil or gas and replaced them with heat pumps and electric appliances, annual greenhouse gas emissions could drop by about 400 million metric tons...

Nov. 26, 2024 -Instead of spewing planet-warming carbon dioxide emissions into the atmosphere, many scientists and startups want to turn the greenhouse gas into valuable chemicals and fuels.

Researchers now report a new method that combines electricity and bacteria to turn carbon dioxide into fatty acids, which can ultimately be converted into biodiesel for vehicles. The process, reported in the journal Joule, is 45 times more efficient and takes about 45th of the land needed to produce biodiesel from soybeans.

Nov. 26, 2024 -Ocean winds whip across the beaches, hillsides and sprawling plains of Hokkaido. There’s enough wind energy here for Japan’s northernmost island to power itself and export clean electricity to the rest of the country.

But Hokkaido can’t harness all of that power unless it has a way to store energy when breezes are blowing and use it later when the gusts die down.

Nov. 23, 2024 -President-elect Donald J. Trump repeatedly promised voters that he would cut energy and electricity prices in half within 18 months of taking office.

His transition team is just now working on a strategy to accomplish this, according to three people familiar with the discussions who asked for anonymity to discuss internal conversations.

Oct. 10, 2024 -In an effort to one-up nature, engineers have created an artificial plant that captures carbon dioxide ten times more efficiently than its natural counterparts. And it generates enough electricity to power a lamp.

The fake plant is built with bacteria-based solar cells, and looks odd. But it offers a fun, novel concept to tackle two important issues: carbon dioxide removal and clean electricity generation.

Sep. 24, 2024 -Restringing existing electric power infrastructure with more powerful lines could double transmission capacity on many long-distance conduction lines while saving money and cutting through bureaucratic red tape, according to a new study. The approach could also reduce costs for consumers but has been largely ignored in the United States until now.

July 11, 2024 -A Climate Change Conversation With Bill Gates: When the topic turned to the issue of just how much energy artificial intelligence was using, Gates was surprisingly sanguine.

A.I. data centers represent a relatively small additional load on the grid, Gates said. What’s more, he predicted that insights gleaned from A.I. would deliver gains in efficiency that would more than make up for that additional demand.

July 11, 2024 -You wouldn’t choose algae of all things as a beast of labor, but in the microscopic world, these microorganisms are veritable workhorses. Researchers in Japan harnessed the motion of green algae cells by attaching micromachines, including a “scooter” that moves forward and a “rotator” that might just be the smallest Ferris wheel in the world.

These micromachines, reminiscent of futuristic nanobots, showcase the potential for algae-driven technology. The results are spectacular.

As temperatures and energy bills spike this summer, it might be time to consider installing a heat pump. Despite its name, a heat pump cools your home as well as warming it in winter, but the device is far more efficient than a conventional air conditioner and fossil fuel furnace.

Mar. 15, 2020 (CleanTechnica) -You may not have heard much about the city of Utrecht in the Netherlands since a series of treaties signed there in the spring of 1713 brought an end to the War of Spanish Succession. The city is famous for the number of its residents who rely on bicycles to get around. It built the first bike lane in in the Netherlands in 1885. Last year it built the world’s largest multi-story bicycle parking garage with room for 12,500 bikes.

Now a new development of 6,000 homes in the city’s Merwede district is being planned with bicycles as the preferred mode of transportation. It is expected to be serviced by 20,000 bicycles but no cars, with construction scheduled to begin in 2022. The new 24-hectare community will be home to about 12,000 people and will include 2 new primary schools, a high school, and several health centers, together with an assortment of shops and businesses.

From: Huber Technology -Most companies and agencies today operate with the concept of business sustainability. This is a holistic way of managing a business that includes environmental, social, and financial responsibilities. To meet this triple bottom line, companies must find ways to be cost-efficient, socially responsible, and eco-friendly at the same time.

Heating and cooling facilities uses large amounts of energy, and accounts for much of a company’s operating costs. With new technologies, companies can reduce reliance on fossil fuels while saving money.

Jan. 14, 2021(ScienceDaily)-Just one hour of videoconferencing or streaming, for example, emits 150-1,000 grams of carbon dioxide (a gallon of gasoline burned from a car emits about 8,887 grams), requires 2-12 liters of water and demands a land area adding up to about the size of an iPad Mini.

But leaving your camera off during a web call can reduce these footprints by 96%. Streaming content in standard definition rather than in high definition while using apps such as Netflix or Hulu also could bring an 86% reduction, the researchers estimated.

-With clean energy from the sun and wind, we have the technology to provide for our energy needs without the global consequences of pollution. Yet we’re still producing and consuming virtually all of our energy in ways that do lasting damage to our environment, our health and our climate. And to make matters worse, of all that dirty energy we produce, two-thirds of it ends up being wasted.

We can address the largest environmental challenges of our time by shifting toward 100% renewable energy. The fastest, easiest and cheapest way to do that is to first reduce the total amount of energy we use and let go to waste. Learn how you can reduce your energy waste and become more energy efficient in your home.

The article tells about the many ways we can save power and reduce both our carbon footprint and utilty bills.

Everyone loves electric cars�they’re clean, fun to drive, and increasingly affordable to own. But what do electric vehicles (EVs) mean for the electricity grid? Could they enable the use of more renewable power?

Drivers, electric utilities, and the environment can all benefit when electric vehicles are better integrated with the grid.

July 2020, (Bloomberg Green)-In Singapore, close to the Equator, temperatures regularly rise above 32 degrees Celsius (90 Fahrenheit) � but inside the soaring glass greenhouses of Gardens by the Bay, the country’s award-winning botanical park, it’s a pleasant 24 degrees.

The daffodils and tulips of the flower dome, along with two dozen nearby towers that are normally full of bankers, shoppers, residents, hotel guests and gamblers, are chilled by what is probably the world’s largest underground district cooling system.

Feb. 7, 2017- Taxa Outdoors’ tow camper, the TigerMoth, is a compact home on wheels geared towards traveling adventurers. The lightweight camper sleeps two, has LED lights, and even better, comes with a built-in electrical system that generates energy while being towed. The camper’s battery can store energy for at least seven days, making off-grid living easier than ever before.

Solar and wind are poised to become a larger part of that green-power mix. But there’s a problem: people need electricity even when the sun’s not shining and the wind isn’t blowing.

One way to solve this problem is to store the excess energy and then release it when there’s a need.

Energy conservation is probably not the first thing that comes to mind when you think about freeways jammed with idling vehicles.

But in California, which has some of the most congested freeways in the country, that's about to change. The CEC has approved a pilot program in which piezoelectric crystals will be installed on several freeways.

An international team of engineers, physicists, and chemists have created the first fiber-optic solar cell. These fibers are thinner than human hair, flexible, and yet they produce electricity, just like a normal solar cell. The US military is already interested in weaving these threads into clothing, to provide a wearable power source for soldiers.

Mar. 30, 2022, (ENERGY.GOV)-Geothermal heat pumps (GHPs), sometimes referred to as GeoExchange, earth-coupled, ground-source, or water-source heat pumps, have been in use since the late 1940s. They use the relatively constant temperature of the earth as the exchange medium instead of the outside air temperature.

Although many parts of the country experience seasonal temperature extremes -- from scorching heat in the summer to sub-zero cold in the winter�a few feet below the earth's surface the ground remains at a relatively constant temperature. Depending on latitude, ground temperatures range from 45°F (7°C) to 75°F (21°C).

Apr. 1, 2021 (ZME Science) -Seemingly small changes in lifestyle can add up to have a huge impact at the societal level. According to a new study, choosing to bike rather than drive a car may reduce the average person’s transportation-related carbon emissions by 67%.

These findings apply for choosing to bike over driving a car only once over the course of a day, meaning you don’t have to substitute all car trips in order to make a huge dent in your carbon footprint. This also means you could reduce your transportation-related emissions by 95% if you choose to exclusively bike.
