Emissions regulations do have an environmental impact, according to a long-term study of acidic rainfall by researchers at the University of Illinois at Urbana-Champaign.

NCAR Wind Forecasts Save Millions of Dollars for Xcel Energy

The National Center for Atmospheric Research (NCAR) has developed a highly detailed wind energy forecasting system with Xcel Energy, enabling the utility to capture energy from turbines far more effectively and at lower cost. The system, which Xcel Energy formally took over last month, saves ratepayers several million dollars yearly.



Wind Energy Lessens Under Heat Wave Conditions

During the summer 2003, high temperatures and drought conditions in Europe led to a reduction of the wind force with direct consequences on the wind energy power, reduced by 22 percent. The study was recently published in Journal of Climate.

Tropical Forests Fertilized By Air Pollution

Scientists braved ticks and a tiger to discover how human activities have perturbed the nitrogen cycle in tropical forests. Studies at two remote Smithsonian Institution Global Earth Observatory sites in Panama and Thailand show the first evidence of long-term effects of nitrogen pollution in tropical trees.
