America’s reliance on gasoline-powered vehicles has long contributed to air pollution, including global warming emissions, and our nation’s dependence on oil. In the past decade, however, the automobile market has begun to change, integrating new technologies that are dramatically less dependent on gasoline. Hybrid electric vehicles, powered in part by energy stored in a battery, have become increasingly popular.
As summer approached, the dangers of our continued dependence on oil are apparent everywhere we look. In 2012, we have already experienced the hottest average temperatures ever recorded through April in the United States. At the same time, increasing evidence is still coming forth of long-lasting harm from the BP oil spill, and other tragic spills have occurred in waterways throughout the country since.
We can save money and help solve global warming by reducing the amount of energy we use, including in the buildings where we live and work every day. More than 40 percent of our energy — and 10 percent of all the energy used in the world — goes toward powering America’s buildings.
Weather disasters kill or injure hundreds of Americans each year and cause billions of dollars in economic damage. The risks posed by some types of weather-related disasters will likely increase in a warming world. Scientists have already detected increases in extreme precipitation events and heat waves in the United States, and the Intergovernmental Panel on Climate Change recently concluded that global warming will likely lead to further changes in weather extremes.
