Wind turbines could help capture carbon dioxide while providing power

Most human-produced CO2 is high in the air. Turbines could funnel it to the ground for removal

Wind turbines stand near a coal-fired power plant in Germany, with steam rising from the plant's cooling towers.

Wind turbines like these near a power plant near Bergheim, Germany, can pull CO2 into their wakes in order to send it to machines that capture the greenhouse gas in the battle against climate change, simulations and a scaled-down wind tunnel test suggest.
