[EXCLUSIVE] Generating Controversy
– by Josh Schlossberg, Earth Island Journal
Kevin Bundy has tramped through his share of forests in California’s Sierra Nevada. Where he sees a diverse ecosystem of ponderosa pine, incense cedar, and white fir, prime wildlife habitats, and one of the world’s best buffers against climate change, many public and private land managers see something different. Of course, they too observe living forests, but they also see tinder for future wildfires, as well as an opportunity to procure home-grown, renewable biomass energy.
A senior attorney with the conservation group Center for Biological Diversity, Bundy works at the national level to ensure strict accounting of carbon emissions from the burning of biomass, and on the local level to limit the type of fuels burned by biomass facilities. He’s convinced that the nation needs to “get away from fossil fuels and shift to 100 percent renewable energy as quickly as possible,” given the threat of climate change. But while he acknowledges biomass might be renewable “in some sense,” he sees it as “something of a false solution to our climate and energy challenges” compared to other renewable sources like solar and wind.
Yet biomass is big business in the United States. In 2014, half of “renewable” energy in the US came from bioenergy – that is, from burning trees, crop residues (most often from corn and soybean harvests), manure, and even trash to produce electricity and heat, or to manufacture liquid transportation fuels like ethanol or biodiesel. Meanwhile, hydropower accounted for 26 percent, wind made up 18 percent, and solar accounted for a mere 4.4 percent. A significant increase in biomass energy production is likely as the US tries to ramp up its renewables output.
There remains considerable debate about just how prominently biomass should feature in energy planning, what with disagreements about the impact it has on forests and agricultural land, how clean it is, and its contributions to climate change. Much of the public is also confused about how biomass compares to other forms of renewable energy. This confusion reflects the conflicting scientific opinions and government policies regarding biomass energy.
