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]

anyone else have lower #solar energy production these last 2 months? I want to blame cloudy weather but thought i would see what others are experiencing!

2025: A landmark year for solar energy
The IEA-PVPS 2025 Snapshot of Global PV Markets reveals a pivotal moment for solar power: global PV capacity surpassed 2.2 TW, with more than 600 GW installed in 2024 alone. As module prices fell due to oversupply, installation volumes continued to grow, highlighting both the strength and volatility of the global PV industry.

India’s solar potential estimated at 10.8 TW
A new study by the Energy and Resources Institute (TERI) has estimated India’s total solar potential at 10,830 GW, significantly higher than the previous 2014 assessment of 748 GW by the Ministry of New and Renewable Energy (MNRE). The study revisits conventional solar deployment areas such as barren and unculturable lands and explores additional avenues to expand the country’s solar potential.

In the final talk of the morning sessions of the #SolarEclipse Conference Thoby Dittrich talked about the Modern Eddington Experiment (the website https://moderneddingtonexperiment.org is under heavy construction): the best observing result of gravitational deflection of starlight by the Sun in the optical during solar eclipses is still Brun's from 2017 - https://arxiv.org/abs/1802.00343 - while others have tried with a vengeance since. The goal remains to observe the significant deflection of star positions between 1 and 2 solar radii from the center of the Sun: this is known as the 'forbidden zone' because the corona can be very bright here and only bright stars can be measured reliably - but those in turn are rare. It turns out that the star fields around the totally eclipsed Sun in 2027 and 2028 will be unusually rich in good candidates so there is (or should be) considerable interest in the physics didactics community to make use of these eclipses in southern Spain / northern Africa and Australia, respectively. 4/n

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.

Very interesting talks at the #SolarEclipse Conference - https://www.vvs.be/subsite/sec-2025/programme - in Belgium I am attending online: here is the key result by Luca Quaglia who had reported his work in great detail in the papers https://iopscience.iop.org/article/10.3847/1538-4365/ac1279 (2021), https://www.iota-es.de/JOA/JOA2022_2.pdf#page=3 (2022) and https://www.iota-es.de/JOA/JOA2024_4.pdf#page=3 (2024) already. There seems to be NO way by now to escape the conclusion the the solar - i.e. photospheric - diameter used by many in the past (and various eclipse map calculations sites still today) is too small. So everyone should use Quaglia's free precision tools at https://www.besselianelements.com instead to get the real length of totality at one's observing spot. And when you are observing at the edges of the totality zone the tools will tell you where the actual border is: traditional maps can the off by some margin! 1/n
