ON THE COVER
Drax power station, the
largest in the United
Kingdom, is expected to
burn 7.5 million metric
tons of biomass in 2017,
mainly wood pellets
from U.S. forests. Many
countries classify wood
as a carbon-neutral fuel and encourage its
use to produce electricity. But any climate
benefits may take decades to materialize.
