Link suite overview on solar scale up: better tech, lower costs, variety, better batteries and bottle bulbs
The shades may have been drawn on Solyndra, but the sun still shines on solar. Despite Big Carbon’s industry front group-funded campaign to sell us on a fossil-fueled future, solar is going mainstream fast. Even heads deeply buried in tar sands can sense the shift.
There is no “one” solar answer. Solar comes in all shapes and sizes: from rooftop panels and peel-and-stick window film, to boats and backpacks, solar “ivy” and solar “leaves,” giant concentrated solar arrays and recycled plastic bottles. Almost daily there is news of improved efficiency, better batteries and more products available off-the-shelf.
Costs are tumbling, too—and not just because the Chinese have heavily subsidized the manufacture of photovoltaic panels, undercutting everyone else in the market. Solar, finally, is enjoying the benefits of scaling up.
This year, the Department of Energy’s biannual Solar Decathlon saw home construction costs come in third cheaper than in 2009. The expense and learning curve of prototypes has given way to the savings of lessons learned.
There are also more jobs—and better-paying local jobs, too—in installation than in manufacturing, lessening the sting of market share loss to China. In the wake of Hurricane Katrina, groups such as the Make It Right Foundation created “a teachable moment,” to train builders and appliance installers to work with greener technologies. Even the cleanest of coal (energy’s reigning oxymoron) cannot compete against a smartly designed solar home whose monthly electric bill comes in under $30.
It is that kind of bargain-happy free market decision-making that has Chevron—yes, Chevron—scrapping pricey natural gas in favor of a concentrated solar power (CSP) array to heat water for steam to to make heavy crude oil thin enough to pump: new sun to mine ancient sun. Beyond the obvious irony, this promises to quickly ramp up into a multi-billion dollar business.
Elsewhere, vast arrays of photo voltaic panels are sprouting everywhere, from a capped garbage dump turned “energy park,” to a Victorian-era London bridge. Both are pilot projects, but expect many more to follow. There are an estimated 100,000 aging landfills in the US prime for PV.
Cutting right to the chase—no power generation required—in the Philippines, soda bottles are being recycled into 55 watt wireless lights through an ingenious design courtesy of MIT’s D-Lab. “Bottle bulbs” inserted into tin roofs bring free daylight into otherwise dark interiors, reducing the need—and expense—of air-fouling kerosene.
So let there be light! And power. And cheaper energy. And a cleaner planet, too.
