The Tesla Model Y has topped Sweden’s automotive registrations regardless of powertrain type in the first half of 2024, as shown in new data.

The Model Y was the most-registered vehicle in Sweden in the first six months of this year, according to data from Mobility Sweden reported by Carup on Monday. The Model Y topped the charts overall with 7,386 units registered, despite a 20 percent decline in overall EV sales. The Model 3 landed 14th overall in the six-month period, while electric options from Volvo, Toyota, Polestar, and Volkswagen were also some of the most registered.

“It is gratifying that the proportion of electric cars reached the best for the year in June, but at the same time we see a stagnant market, which leads to a gradually aging vehicle fleet,” said Mattias Bergman, CEO of Mobility Sweden. “In order to meet the climate goals and strengthen Sweden’s competitiveness, it is crucial that electrification is accelerated.”

RPTU University of Kaiserslautern-Landau has shown for the first time, in a joint study with BOKU University, that permaculture brings about a significant improvement in biodiversity, soil quality and carbon storage.

In view of the challenges of climate change and species extinction, this type of proved to be a real alternative to conventional cultivation—and reconcile and .

Permaculture uses natural cycles and ecosystems as blueprint. Food is produced in an agricultural ecosystem that is as self-regulating, natural and diverse as possible. For example, is integrated into the cultivation of crops or the diversity of beneficial organisms is promoted in order to avoid the use of mineral fertilizers or pesticides.

Tesla Energy is no longer a sleeping giant. During the second quarter of 2024, Tesla Energy was able to deploy 9.4 GWh of energy storage products. This represents the highest quarter deployment of energy storage products in Tesla’s history to date.

Tesla Energy was already a standout in the company’s Q1 2024 Update Letter. In the document, Tesla highlighted that Q1’s energy deployments were a new record at 4.1 GWh. As could be seen in Tesla’s Q2 2024 production and delivery report, Q1’s already impressive 4.1 GWh of energy storage deployments grew an astounding 132% quarter-over-quarter and 157% year-over-year.

$TSLA BREAKING: Tesla distributed 9.4 GWh of energy storage in the second quarter of 2024.

Scientists have found three new species that are close relatives to the plant from which chocolate is produced—a discovery that could pave the way for climate-proof chocolate. The team’s research has been published in the journal Kew Bulletin.

The , discovered in the rain forests of South America, are closely related to Theobroma cacao, the tree that bears which are of tremendous economic importance.

The research team comprising scientists from University College Cork (UCC), the University of São Paulo and New York Botanical Garden say their finding is significant as it indicates that there is much work still to be done in characterizing Earth’s biodiversity.

A research effort led by scientists at the U.S. Department of Energy’s (DOE’s) National Renewable Energy Laboratory (NREL) has made advances that could enable a broader range of currently unimagined optoelectronic devices.

The researchers, whose previous innovation included incorporating a perovskite layer that allowed the creation of a new type of polarized (LED) that emits spin-controlled photons at room temperature without the use of magnetic fields or ferromagnetic contacts, now have gone a step further by integrating a III-V semiconductor optoelectronic structure with a chiral halide perovskite semiconductor.

That is, they transformed an existing commercialized LED into one that also controls the spin of electrons. The results provide a pathway toward transforming modern optoelectronics, a field that relies on the control of light and encompasses LEDs, solar cells, and telecommunications lasers, among other devices.

A theoretical model for the illumination of photosynthesizing algae in giant clams suggests principles for high efficiency collection of sunlight.

Crops on a farm capture only about 3% of the available solar energy, much less than the 20%–25% captured by large solar arrays. Now a research team has used a theoretical model to explain efficiencies as high as 67% for photosynthesizing algae hosted by giant clams [1]. The researchers argue that clams achieve this performance with an optimized geometry. The mollusks may also adjust the algae clusters’ spacing according to changing light conditions. The researchers hope that an understanding of clams’ solar efficiency might help other scientists improve the efficiency of solar technology and explain aspects of the photosynthetic behavior of other ecosystems such as forests.

A photosynthetic cell can convert nearly every incoming photon to usable energy, says biophysicist Alison Sweeney of Yale University. But efficiency is much lower in larger systems such as agricultural fields. “Can we achieve near-perfect efficiencies over large land areas? This is an urgent question” as researchers try to reduce reliance on fossil fuels, Sweeney says.

Year 2023 Basically solar will last several billion years and make type 0 civilization resources obsolete by making trillions of dollars in profits with nearly zero emissions.

Between the Covid-19 pandemic, the Ukraine conflict, inflation, and the renewables transition, the 2020s have been a volatile decade for energy. The pandemic reduced demand for electricity and oil all over the world, causing prices to plummet. Then the Ukraine invasion brought sanctions on Russian oil and gas, pushing energy prices up and leaving European countries scrambling (particularly for natural gas). High energy prices have since contributed to inflation, and in many places utility costs are far surpassing inflation. All the while, worry over climate change has continued to mount, with calls to reduce our dependence on fossil fuels growing ever louder.

In short, the energy situation in the US and around the world is a mess. But the International Energy Agency released some good news in its recent World Energy Investment report. The report is compiled annually, and the 2023 version came out at the end of May. For the first time ever, it found that investment in renewables—specifically solar power—will overtake spending on oil.

The IEA estimated that a total of $2.8 trillion will be invested in energy globally this year, with clean energy accounting for more than $1.7 trillion of that total. The “clean” designation includes renewables like wind, solar, and hydro, but also nuclear power, grids, storage, low-emission fuels, efficiency improvements, and electrification (such as replacing combustion-engine cars with electric cars). The remainder of the $2.8 trillion total, about $1 trillion, will go to oil, gas, and coal, with 15 percent going to coal specifically.

Tesla Gigafactory Berlin has probably become the most fun factory among the company’s facilities worldwide. While Giga Berlin plays a huge part in ramping Tesla’s output globally, the electric vehicle maker also seems determined to ensure that the facility’s employees are well supported. This means that if employees need to destress, they would not need to go too far.

With this in mind, it appears that Giga Berlin has launched an in-house “rave cave” of sorts. The facility’s teaser was posted by Tesla’s official Tesla Manufacturing account, which, strangely enough, shared its post with a hamster emoji. Amidst scenes of employees entering the apparent “rave cave” from a futuristic narrow tunnel, images of a cyber-hamster mascot could also be seen.
