State Renewable Energy Goals Fall Short, Analysis Finds

Methane from farm animals that is burned to produce electricity is counted toward renewable energy goals in a number of states. (Photo: U.S. Department of Agriculture) More than half of all U.S. states have adopted renewable energy goals, but many allow dirty sources of power to be counted and efforts overall are currently too weak to prevent “potentially irreversible” climate change, a new report from Food & Water Watch says. The Washington, D.C., based advocacy group examined the regulatory fine print of renewable portfolio standards (RPS) in 29 states and the District of Columbia and concluded that only a handful…


A Green Guide to Choosing a Christmas Tree

Environmentally conscious consumers often ask me whether a real Christmas tree or an artificial one is the more sustainable choice. As a horticulture and forestry researcher, I know this question is also a concern for the Christmas tree industry, which is wary of losing market share to artificial trees. And they have good reason: Of the 48.5 million Christmas trees Americans purchased in 2017, 45 percent were artificial, and that share is growing. Many factors can influence this choice, but the bottom line is that both real and artificial Christmas trees have negligible environmental impacts. Which option “wins” in terms…

U.S. Team Wins Solar Decathlon Middle East

Virginia Tech’s entry, FutureHAUS Dubai, emerged as the winner in the inaugural Solar Decathlon Middle East last month, outscoring entries from 14 other groups. In an announcement, the university said the project was the result of years of research and development and relied on the contributions of more than 100 students and faculty members. Virginia Tech prevailed despite a warehouse fire that destroyed an early prototype and wiped out years of work, forcing the team to start from scratch in early 2017. The U.S. Department of Energy launched the Solar Decathlon competition in 2002 to encourage collegiate teams to design…


Forest Management and Wildfires

President Donald Trump’s recent comments blaming forest managers for catastrophic California wildfires have been met with outrage and ridicule from the wildland fire and forestry community. Not only were these remarks insensitive to the humanitarian crisis unfolding in California, they also reflected a muddled understanding of the interactions between wildfire and forest management. As scientists who study forest policy and community-based collaboration, here is how we understand this relationship.
