Brazil generates 88% of power from renewables in 2024
Brazil’s electricity mix was 88% renewable in 2024, with wind and solar supplying about 24% of total demand, according to new data from state-owned energy agency Empresa de Pesquisa Energetica (EPE).

The world's data centers already consume three times as much electricity as Dutch national consumption. And this is expected to grow to 8 times within five years.

Investment Risk for Energy Infrastructure Construction Is Highest for #NuclearPower Plants, Lowest for #Solar

Investment Risk for Energy Infrastructure Construction Is Highest for Nuclear Power Plants, Lowest for Solar - CleanTechnica
A new study from the Boston University Institute for Global Sustainability finds that construction costs run over budget for more than 60% of energy infrastructure projects worldwide. By Laura Hurley Between now and 2050, the International Energy Agency projects that more than $100 trillion will be spent on building net-zero energy infrastructure globally. ... [continued]

Balcony solar took off in Germany. Why not the US?
From breaker-masking to voltage mismatches to building safety codes, America’s grid isn’t ready for balcony solar power — yet.

I got myself a portable solar panel, which I can use while camping and at home for charging power banks. I’m very impressed with how well it works, even on a cloudy day! The purpose of the panel is basically to power my power banks so I have green energy to charge my phone, tablet, headphones, USB lights, and electric toothbrush. It’s not much, but every bit helps to keep the bill lower.

Superstrate structured Sb$_2$S$_3$ thin-film solar cells by magnetron sputtering of Sb and post-sulfurization
We report on the fabrication and optimization of semi-transparent antimony sulfide (Sb$_2$S$_3$) thin-film solar cells in a superstrate configuration, using RF magnetron sputtering of metallic antimony followed by post-deposition sulfurization. The influence of absorber and buffer layer thicknesses on device performance was systematically studied in FTO/CdS/Sb$_2$S$_3$/Spiro-OMeTAD/Au architectures. Optimizing the Sb$_2$S$_3$ absorber thickness to 100 nm yielded a champion device with a power c…

De-Biasing Structure Function Estimates From Sparse Time Series of the Solar Wind: A Data-Driven Approach
Structure functions, which represent the moments of the increments of a stochastic process, are essential complementary statistics to power spectra for analysing the self-similar behaviour of a time series. However, many real-world environmental datasets, such as those collected by spacecraft monitoring the solar wind, contain gaps, which inevitably corrupt the statistics. The nature of this corruption for structure functions remains poorly understood - indeed, often overlooked. Here we simulat…

A Polarimetry-based Field-deployable Non-interruptive Mirror Soiling Detection Method
The soiling level of heliostat mirrors in Concentrated Solar Power (CSP) fields is one of the key factors that significantly influences optical efficiency. State-of-the-art methods of monitoring heliostats soiling levels still face various challenges, including slow speed, labor-intensive operations, resolution and accuracy constraints or interruptions to solar field operations. We present a rapid, cost-effective, and non-intrusive method for mirror soiling detection based on polarimetric imagi…

Time path of turbulence and multi-fractality of magnetic field in the evolution of an active region
Magnetograms acquired with the Helioseismic and Magnetic Imager (HMI) on board the Solar Dynamics Observatory (SDO) were used to calculate and analyze time variations of turbulence and multifractality in the photosphere during the development and flaring of a mature active region NOAA 13354 during its passage across the solar disk. Turbulence was explored with 2D magnetic power spectra from magnetograms, and multifractality was analyzed using the structure functions of magnetograms. Time vari…

I looked into buying a solar charged battery bank. This product category is completely dominated by no-name 3rd party sellers. 🚩
Charge time is key. No listing had even a rough estimate for solar charge time. 🚩
An example unit claims max solar power 1.13 w, with enough battery power to charge an iPhone 14 Pro twice. Working from that, you'd need ~25 hours of full sun to fully charge. I'd roughly estimate that means at least 3 days in summer. Not quite worthless, but close…

Might be a shot in the dark, but is there anyone out there self-hosting Navidrome on a Raspberry Pi (or other device), and powering it using solar power?

It's funny how these old closed down coal power plants are coming back online since PJM won't allow crypto mining onto the electric grid. Solar farms are popping up all over (confused because they could do so much better in other places than where it's cloudier than Seattle), but they aren't allowed to connect because a national company forgot to obtain a permit by some hillbilly township with a population of 3.

Asteroseismology of the G8 subgiant beta Aquilae with SONG-Tenerife, SONG-Australia and TESS
We present radial velocities of the G8 subgiant star beta Aql obtained in 2022 and 2023 using SONG-Tenerife and SONG-Australia. We also analysed a sector of TESS photometry that overlapped with the 2022 SONG data. We processed the time series to assign weights and to remove bad data points. The power spectrum clearly shows solar-like oscillations centred at 430 muHz. The TESS data show the oscillations at lower signal-to-noise because photometric measurements are much more affected by the granu…

Heliostat Optical Error Inspection with Polarimetric Imaging Drone
On a Concentrated Solar Power (CSP) field, optical errors have significant impacts on the collection efficiency of heliostats. Fast, cost-effective, labor-efficient, and non-intrusive autonomous field inspection remains a challenge. Approaches using imaging drone, i.e., Unmanned Aerial Vehicle (UAV) system integrated with high resolution visible imaging sensors, have been developed to address these challenges; however, these approaches are often limited by insufficient imaging contrast. Here we…

Composite material keeps solar panels cool, boosting longevity by more than 200%
A team of international researchers led by King Abdullah University of Science and Technology (KAUST) in Saudi Arabia has developed a new composite material made of acrylate that enhances the performance of solar cells. Adhering the composite material to solar cells deployed in Saudi Arabia for weeks significantly raised the power output and longevity while reducing the electricity consumed by the cells. The study can be read in Materials Science and Engineering: R: Reports.
