A series of mega-solar projects are being constructed in Arizona and
California. The company Brightsource has already begun construction on
the 370 MW Ivanpah project. In October, the U.S. Department of the
Interior approved an application for construction of the Blythe Solar
Power Project, consisting of four solar thermal arrays that will produce
250 MW each. Seven other projects are expected to break ground before
the end of the year with a combined capacity of 4,000 MW when completed.
Activists are pressuring the Obama Administration to take leadership
on solar policy, and recently scored a symbolic victory that they hope
will bring solar more public attention and cachet and lead to policy
change.
This fall, Bill McKibben, founder of the climate activist
organization 350.org, and a group of students from Unity Signs of Life College traveled down the East Coast with one of the original solar
hot water panels that President Jimmy Carter installed on the White
House in 1979. (Reagan removed them in 1986.) Along the way (and
online), the group collected 40,000 signatures petitioning the White
House to resurrect the panels. The White House initially rebuffed the
request. But on October 5, U.S. Department of Energy Secretary Steven
Chu announced that the White House plans to install photovoltaic panels
and a solar hot water heater on its roof.
"The Obama announcement has sparked this campaign to rev up in a
number of other places around the world," says Jamie Henn,
communications director with 350.org. On October 10, the day of a Global
Work Party coordinated by 350.org, President Mohamed Nasheed of the
Maldives also installed a set of solar panels, by hand, on the
presidential residence.
Illinois Gov. Pat Quinn has committed to putting solar on the
governor’s mansion, and Australians have launched a campaign to pressure
Prime Minister Julia Gillard to put solar on the Lodge, her official
residence.
Activists believe the White House gesture will also make solar seem
more accessible to the average American homeowner. In his announcement,
Chu said the White House panels "will show that American solar
technology is available, reliable, and ready to install in homes
throughout the country."
Meanwhile, recent technological breakthroughs may makehome solar
power much more affordable. An interdisciplinary team at Western
Washington University (WWU) announced in September a $970,000 grant
from the National Science Foundation for additional research on a new
kind of solar collector. Traditional photovoltaic panels use only the
red band of visible light. The WWU team’s collector uses colored
polymers to gather light from the whole spectrum. The increased
efficiency allows electrical generation on overcast days and will cut
the cost of solar panels by as much as 90 percent, according to a WWU
press release.
