Electric Heat Pumps Can Slash Emissions in California Homes

Written in collaboration with Anna Brockway from the Energy & Resources Group at the University of California Berkeley. Using high-efficiency electric heat pumps instead of gas for residential heating needs in California could cut greenhouse gas (GHG) emissions in half or more, according to a new Natural Resources Defense Council  analysis published in the Electricity Journal. This makes heat pumps an important tool to help achieve California’s ambitious goals to cut GHG emissions 40% by 2030, achieve carbon-neutrality by 2045, and improve air quality in its urban areas — which rank among the most polluted in the country. We found…


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…
