Tesla is building a 100MW energy storage project in Texas
In Angleton, a town of nearly 20,000 located 40 miles south of Houston, Tesla subsidiary Gambit Energy Storage is installing the company’s modular Megapacks.
Denmark will build a wind-generating artificial island in the North Sea
The long-rumored island is expected to begin operations in 2033.
Europe created more energy from renewables than fossil fuels last year
Europe is slowly reducing its dependancy on fossil fuels. A report co-published by Ember and Agora Energiewende, two think tanks focused on clean energy, has revealed that the continent generated more electricity from renewables than fossil fuels in 2020.
Saudi Arabia is planning a 100-mile line of car-free smart communities
Saudi Crown Prince Mohammed bin Salman is promising to build a network of smart cities that won’t have any cars or roads. It’s called The Line, due to its arrangement of ”hyper-connected future communities,” and will form part of NEOM, a $500 billion project announced in October 2017. According to the prince, the development will offer “ultra-high-speed transit,” autonomous vehicles and an urban layout that ensures basic facilities, such as schools and medical clinics, are never more than a five-minute walk away.
Fusion energy device sets a record by running for 20 seconds
A Korean fusion device has set a record by running for 20 seconds at 180 million degrees.
Nest makes its Seasonal Savings program free for all thermostat users
The feature makes small tweaks to Nest thermostat settings to help reduce energy consumption. Until now, Seasonal Savings were only available if a customer’s utility provider offered Seasonal Savings programs.
Tesla's solar panels are now more efficient and affordable
Tesla's solar panels are now about 10 percent more efficient. They're also more affordable.
Denmark's ambitious wind power plans include giant 'energy islands'
Denmark's new wind power project could boost Europe's offshore wine capacity by 54 percent.
Extra-light, flexible solar cell could keep your smartwatch powered
Researchers have built a very light and stretchy solar cell that could keep wearable devices running without batteries.
New York power plant mines Bitcoin using excess energy
A natural gas power plant can't always send excess energy into the grid, frequently leading to waste as the gas is flared or vented away. However, a plant in Dresden, New York thinks it has a solution: use that surplus to generate some digital cash. Greenidge Generation has revealed that it's using "behind-the-meter" energy at the facility to mine Bitcoin, with 7,000 mining systems producing up to 5.5BTC (about $45,000 as of this writing) per day.
AI can help find more places to store captured CO2 underground
Scientists dream of storing captured CO2 emissions underground, but it can be tricky to find pockets for storing those emissions -- Earth's seismic "hum" makes it difficult to spot the low-frequency waves that would best help map the subterranean landscape. That might not be a challenge in the future thanks to AI. MIT scientists have developed a machine learning system that uses earthquakes to accurately estimate those low-frequency waves and map underground structures. The trick, according to researchers, was in the training.
The rise of cloud computing has had a smaller climate impact than feared
As more and more gargantuan data centers come on line, environmentalists have been concerned about massive increases in electricity consumption and pollution. However, according to a new study published in Science, that simply hasn't happened. While cloud computing output has jumped by 600 percent from 2010 to 2018, energy consumption rose by just 6 percent. That's because companies like Google have massively increased efficiencies with new chip designs, custom-tailored airflow solutions and other tech.
Alphabet quits work on its energy-generating kites
Alphabet's years-long involvement with energy-making kites is no more. The Google parent is ending its work on Makani's wind power technology, with X's Moonshot lead Astro Teller warning that the path to a viable business was "much longer and riskier" than expected. Alphabet liked Makani's environmental focus, but felt that it was important to pour effort into those areas where it believed it could "have the greatest impact."
Rain may soon be an effective source of renewable energy
There have been numerous attempt to generate electricity using rain, but this may be one of the more effective solutions yet. Researchers have developed a generator that uses a field-effect transistor-style structure to instantly produce a surprisingly high voltage from water drops -- a single drop can muster 140V, or enough power to briefly light up 100 small LED bulbs. Earlier generators without the structure produced "thousands" of times less instant power density, the scientists said.
Tesla unveils its easier-to-install Solar Roof
After spending a good amount of time talking about Tesla Energy during its earnings call earlier this week, the company announced its new Solar Roof tiles. According to CEO Elon Musk, if you need a new roof, installing these tiles will be cheaper than a new roof and separate solar panels.
Tesla may open 'Centers' to get around pro-dealership laws
Tesla may be planning an end-run around state laws that bar direct car sales and protect dealerships. Electrek sources claim the automaker is planning to open "Tesla Centers" in major urban areas that would theoretically avoid legal trouble by focusing on the sale of energy, not cars. These large outlets would offer sales, service and delivery seven days a week, even in states where "blue" laws prevent conventional car dealerships have to stay closed on Sundays. The strategy would take effect in the fourth quarter of this year.
IKEA will produce more energy than it consumes by 2020
Many companies are pouring money into renewable energy, but how many can say they're producing more than they need? IKEA thinks it will, at least. Its holding company Ingka revealed that IKEA will generate more renewable energy before the end of 2019 than the energy its stores use. The firm only expected to draw even by 2020. The furniture chain added that it had invested about $2.8 billion in solar and wind energy over the past decade, and told Reuters that it intended to continue funding that renewable tech, including two stakes in American solar farms this week.
Three Mile Island's infamous nuclear plant shuts down after 45 years
An important if ignominious chapter in American nuclear energy has come to a close. Exelon has shut down Three Mile Island's Generating Station Unit 1 reactor after 45 years of use. The reactor isn't the one behind the accident in March 1979, but this effectively marks the closure of the plant -- Unit 2, the reactor that failed, has been dormant for the past 40 years. It didn't directly provide a reason, but it had warned in 2017 that it would shut down the plant in 2019 due to the high running costs.
Walmart sues Tesla after solar panels catch fire at stores (updated)
So much for Tesla's renewed solar power efforts getting off to a good start. Walmart has sued Tesla after rooftop solar panels on seven of the retailer's stores caught fire, allegedly due to poor safety practices. Tesla supposedly didn't ground its electrical and solar systems properly, according to Walmart, and regularly sent inspectors who "lacked basic solar training and knowledge." Walmart also asserted that Tesla's panels were rife with visible defects.
