Iceland Just Found Its First Mosquitoes

1 month 1 week ago
An anonymous reader quotes a report from CNN: Iceland's frozen, inhospitable winters have long protected it from mosquitoes, but that may be changing. This week, scientists announced the discovery of three mosquitoes -- marking the country's first confirmed finding of these insects in the wild. Mosquitoes are found almost everywhere in the world, with the exception of Antarctica and, until very recently, Iceland, due to their extreme cold. The mosquitoes were discovered by Bjorn Hjaltason in Kioafell, Kjos, in western Iceland about 20 miles north of the capital Reykjavik. "At dusk on October 16, I caught sight of a strange fly," Hjaltason posted in a Facebook group about insects, according to reports in the Icelandic media. "I immediately suspected what was going on and quickly collected the fly," he added. He contacted Matthias Alfreosson, an entomologist at the Natural Science Institute of Iceland, who drove out to Hjaltason's house the next day. They captured three in total, two females and a male. Alfreosson identified them as mosquitoes from the Culiseta annulata species. A single mosquito from a different species was discovered many years ago on an airplane at the country's Keflavik International Airport, Alfreosson told CNN, but this "is the first record of mosquitoes occurring in the natural environment in Iceland." Further monitoring will be needed in the spring to see whether the species can survive the winter and "truly become established in Iceland," Alfreosson said. He said he's not sure climate change played a role in the discovery but "warming temperatures are likely to enhance the potential for other mosquito species to establish in Iceland, if they arrive."

As Texas Power Demand Surges, Solar, Wind and Storage Carry the Load

1 month 1 week ago
Texas's electricity demand has surged to record highs in 2025 but renewable energy is meeting the challenge. According to new data from the Energy Information Administration, solar output has quadrupled since 2021, wind continues steady growth, and battery storage is increasingly stabilizing the grid during evening peaks. Electrek reports: ERCOT, which supplies power to about 90% of the state, saw demand jump 5% year-over-year to 372 terawatt hours (TWh) -- a 23% increase since 2021. No other major US grid has grown faster over the past year. [...] The biggest growth story in Texas power generation is solar. Utility-scale solar plants produced 45 TWh from January through September, up 50% from 2024 and nearly four times what they generated in 2021 (11 TWh). Wind power also continued to climb, producing 87 TWh through September -- a 4% increase from last year and 36% more than in 2021. Together, wind and solar supplied 36% of ERCOT's total electricity over those nine months. Solar, in particular, has transformed Texas's daytime energy mix. From June to September, ERCOT solar farms generated an average of 24 gigawatts (GW) between noon and 1 pm -- double the midday output from 2023. That growth has pushed down natural gas use at midday from 50% of the mix in 2023 to 37% this year. The report notes that while natural gas is still Texas's dominant power source, it isn't growing like it used to. "Gas comprised 43% of ERCOT's generation mix during the first nine months of 2025, down from 47% in the first nine months of 2023 and 2024," reports Electrek.
