Hidden costs lurk everywhere.
Buy a car on credit and pay double the sticker price. Same with a house. For instance, adjustable mortgages and balloon payments contributed mightily to the real estate meltdown. And taxes take a big bite. Just ask any small businessperson.
Maybe that's why we Americans like our energy costs low, or at least relatively.
But there are hidden costs there, too. Harvard Medical School's Center for Health and the Global Environment released a study that pegged the estimated hidden yearly cost of coal-generated electricity at a high of $538 billion, or an additional 18 cents per kilowatt hour. Peswiki.com listed the commercial cost of coal power at 4.8 to 5.5 cents per kWh.
For some perspective, solar costs between 15 to 30 cents per kWh and wind 4 to 6 cents.
Heavy burden
"Coal carries a heavy burden," the "Mining Coal, Mounting Costs" report said. The Harvard study factored in health costs (11,000 deaths annually from lung cancer, heart, respiratory and kidney disease) and environmental impacts of fly ash spills (53 from 1974 to 2008) and mountaintop removal (500 removed and 1.4 million acres transformed).

Algae fuel and solar could use a little entrepreneurial True Grit
Developments in solar and biofuels lead me to believe that the sunny San Joaquin Valley could indeed become a leader in the emerging clean energy industry.
My friend Sandy Nax has called the Valley a Petri dish for alternative energy development because it has so many of the necessary attributes: available land, scorching sun and/or clear days a majority of the year, wind in the mountains and scads of agricultural resources for biofuel or biogas.
Sandy has often said, "Clean energy could be a game changer." He was referring to the economy.
Sandy and I discuss the attributes of the sorry state of economic affairs that have devastated the region's real estate, toppled government tax revenues and put many of our neighbors out of work.
Changing the world
We used to work in the newspaper business, which hasn't fared well these past several years. As part of our jobs writing and editing business stories, we spent years analyzing trends and making sense of them.
This clean energy trend has been fascinating to watch. I still have no idea where it's going and what particular component will be the first to fuel jobs, but indicators have been extremely positive.

UC Merced sets the sustainable bar way, way up
The newest campus in the University of California system is quietly becoming a sustainable model and developing a reputation as a center for world-class research.
The University of California, Merced just had its seventh building certified gold by the U.S. Green Building Council’s Leadership in Energy and Environmental Design, or LEED, program.
Its long-range plan, which embraces economic, social and environmental sustainability in campus facilities, was named to the American Institute of Architects' Committee on the Environment Top 10 Green Projects program.
And physics professor Sayantani Ghosh, along with Richard Inman, Georgiy Shcherbatyuk, Dmitri Medvedko and Ajay Gopinathan recently won recogntion of their research in renewable energy in the clean energy press.
Renewable research leader
Zachary Shahan of cleantechnica.com explains the research breakthrough as an effort "to redesign luminescent solar concentrators in order to make them more efficient at sending sunlight to solar cells."

Solar impulse completes flight in Ouarzazate, Morocco
The second time's the charm for the Solar Impulse.
The airplane, which is solely powered by electricity and backed by solar energy, took off early from Rabat, Morocco on June 21, 2012 and landed in Ouarzazate, Morocco about 17 hours later. It had failed in its first attempt last week.
Officials said the flight was Solar Impulse’s most difficult destination in its cross-continental journey due to high winds and turbulence over the arid desert.
"It was a beautiful flight," says pilot and project co-founder André Borschberg.
The Solar Impulse made a successful 19-hour 8-minute flight from Madrid, Spain to Rabat, Morocco earlier in June. The month previous, Borschberg, 59, began the journey from Payerne, Switzerland. He landed in Madrid on May 25.
