Emissions hit a record high in 2023. Blame hydropower.
But last year, weather conditions caused hydropower to fall short in a major way, with generation dropping by a record amount. In fact, the decrease was significant enough to have a measurable effect on global emissions. Total energy-related emissions rose by about 1.1% in 2023, and a shortfall of hydroelectric power accounts for 40% of that rise, according to a new report from the International Energy Agency. Between year-to-year weather variability and climate change, there could be rocky times ahead for hydropower.…
