Since 2021, electricity demand within the Texas electricity grid operated by the Electric Reliability Council of Texas (ERCOT) has steadily increased. In the first nine months of 2025, electricity demand in ERCOT, which manages about 90% of the state’s load, reached a record high compared with the same period in previous years. Over those same months, ERCOT had the fastest electricity demand growth among U.S. electricity grids between 2024 and 2025. From January through September 2025, demand for electric power in ERCOT increased 5% compared with the same period in 2024 to 372 terawatthours (TWh), 23% more than the same months in 2021. Since 2023, wind

Under the sea, green algae have evolved a clever way to handle too much sunlight. Scientists found that a special pigment called siphonein acts like a natural sun shield, protecting the algae’s delicate photosynthetic machinery from burning out. Using advanced imaging and simulations, researchers showed how siphonein helps algae safely manage excess light energy. The discovery could inspire new solar technologies that mimic nature’s built-in protection systems.
