Another Californian
carbon-free first
Adorned with energy efficient lights
and powered by a hydrogen fuel cell
system, the California Environmental
Protection Agency's (Cal/EPA) Christmas
tree display is operating completely
independent of the US national power
grid.
Cal/EPA secretary Dr Alan C Lloyd
said: "As these trees bring the
spirit of the holidays to those who
work in and visit our building, I
also hope they will inspire Californians
to find ways to conserve energy and
embrace clean technologies in their
own homes and businesses."
Dr Lloyd pointed out that fuel cells
and other carbon-free technologies
would help California meet Governor
Arnold Schwarzenegger's green house
gas emission reduction targets. Earlier
this year the Governor called on the
Cal/EPA to develop strategies to reduce
greenhouse gas emissions in the state
to 80% below the 1990 levels by the
year 2050.
Cal/EPA Christmas trees are decorated
are decorated with more than 3,000
light-emitting diode (LED) bulbs that
consume about 2% of the electricity
used by traditional incandescent lights
. Additionally, the lights are powered
by a one-kilowatt hydrogen fuel cell
system. The fuel cell system emits
only pure water and allows the lights
to operate without any electricity
form the national power grid.
Eric Mettler, COE of Altergy Systems,
which supplied the hydrogen fuel cell
system, said: "Through the ujse
of fuel cells we are on our way to
creating freedom from foreign oil,
freedom from batteries, and freedom
from pollution."
