Our homes and buildings use a lot of energy. Up to 40 percent of energy bills and carbon dioxide emissions are tied to private homes and commercial buildings. Experts say nearly one-third of this money and energy use is wasted, because many structures were built before modern materials and standards were around.
Climate change scientists know that plants can’t grow larger with extra carbon dioxide unless they also have nitrogen. But a new study coauthored by a Flagstaff ecologist shows fungus can help plants get around that limitation.
In 2015 the EPA issued a Clean Power Plan directing states to limit carbon dioxide emissions from power plants. Under the plan, for example, Arizona will need to cut annual carbon emissions from 40 to 30 million tons by 2030.
The State of Arizona has joined a lawsuit against the U.S. Environmental Protection Agency over the federal Clean Power Plan. It’s among two dozen states fighting the new regulations that limit greenhouse gas emissions from the nation’s power plants. Arizona Public Radio’s Ryan Heinsius reports.
