Hugging a Burning Tree

When most people think of renewable energy sources, they imagine solar panels and wind turbines. Globally, however, biomass – humanity’s oldest fuel – makes up 76% of today’s renewable energy and 10% of all energy, and its rising use promises more risk than reward.

PRAGUE – We are all brought up to recycle paper to save trees. We get countless e-mail admonitions: “Please consider the environment before printing.” Indeed, environmentalism was born with a call to preserve the forests.

But now, in the name of saving the planet from climate change, environmentalists are proposing an immense global campaign to cut down and burn trees and scrubs in order to reduce fossil-fuel use. The initiative could be dismissed as a weird irony, if it weren’t for its phenomenal costs, which include likely destruction of biodiversity, increased water use, and reduced global food production. And it may end up increasing global CO2 emissions to boot.

When most people think of renewable energy sources, they imagine solar panels and wind turbines. Globally, however, solar and wind are only a small part of total renewables – less than 7% in 2010. Hydropower is a much bigger player, at 17%. But the most important by far is biomass – humanity’s oldest fuel makes up 76% of today’s renewable energy and 10% of all energy. About 60% of this is wood, twigs, and dung, used by almost three billion people who lack access to modern fuels – and resulting in terrible air pollution and millions of deaths.

    In Israel's recent parliamentary election, voters stopped Prime Minister Binyamin Netanyahu's leadership of the country toward xenophobic theocracy. But Israel now faces a period of political deadlock, and it remains to be seen whether Netanyahu really will be politically sidelined.

    The Return of Fiscal Policy

    Jim O'Neill

    With interest rates at record lows and global growth set to continue decelerating, there has rarely been a better time for governments to invest in infrastructure and other sources of long-term productivity growth. The only question is whether policymakers in Germany and elsewhere will seize the opportunity now staring them in the face.
