A new approach to assessing greenhouse gas emissions from
coal, wind, solar, and other energy technologies paints a much more
precise
picture of cradle-to-grave emissions and should help sharpen decisions
on what
new energy projects to build.

According
to a new study using SWITCH, a highly detailed computer model of the
electric power grid, University of California, Berkeley researchers have
learned that goals for decarbonization of the electric power sector are
most easily achieved using renewable or nuclear energy sources in lieu
of coal.

In 2009, when the United States
fell into economic recession, greenhouse gas emissions also fell, by
6.59%
relative to 2008. In the power sector, however, the
recession was not the main cause. Researchers at Harvard University have shown that the primary
explanation
for the reduction in carbon dioxide emissions from power generation that
year
was that a decrease in the price of natural gas reduced the industry's
reliance
on coal.

The success of a U.S. Department of Energy (DOE) Clean Coal
Power Initiative (CCPI) project has led to a repayment of $580,000 to
U.S. taxpayers,
with much more—potentially exceeding $13 million—possible in the future.

Scientists
have come up with a possible explanation for why the rise in Earth's
temperature paused for a bit during the 2000s, one of the hottest
decades on record. According to a new study, the culprit was all of the
airborne sulfur pollution from China's massive coal-burning. Despite the
massive output of sulfur, the effect was temporary.

Solid
oxide fuel cells rely on nickel-ceramic anodes that are easily clogged
by carbon-containing fuels. Using barium oxide nanoparticles, however,
Georgia Tech researchers have developed a self-cleaning technique that
could allow solid oxide fuel cells to be powered directly by coal gas at
relatively low temperatures without coking.

Two
Rutgers energy and environment researchers recently completed work on a
long-term study of consumers’ attitudes toward two high-profile energy
sources: coal and nuclear energy. Their work finds that while global
warming and safety do factor into Americans’ decisions on these two
forms of energy, other factors are at play that figure into their
choices.

The
Arctic is warming more rapidly than other regions of the world, and
scientists believe a mostly invisible thin layer of soot is causing it
to absorb more heat. Studies now indicate that cutting the concentration
of short-lived pollutants, such as soot, will reduce the rate of
warming in the Arctic faster than cuts in carbon dioxide and other
greenhouse gases.

A
Michigan utility spent $65 million last year replacing key parts at the
state's largest coal-fired power plant, but when regulators found out
the brought DTE Energy to court for not also installing technology that
would greatly reduce air pollution. The case highlights the
industry-wide tug-of-war between compliance with EPA rules and the cost
of new technology.

In a recent article in Nature, Lawrence Berkeley National
Laboratory scientist David Fridley argues that coal prices around the
world
will likely soar in coming years, due partly to explosive demand from
China,
and that energy policies relying on the conventional wisdom of plentiful
cheap
coal need to be reconsidered.
