Energy’s Sunny Future

New Technology Enables Solar Power to Go Global

by Linda Sechrist

GL_1014_SolarPower“I’d put my money on the sun and solar energy. What a source of power!

I hope we don’t have to wait until oil and coal run out before we tackle that.”

~ Thomas Alva Edison in 1931

Energy Engine

Humankind has sought for centuries to harness the Sun because the cumulative energy of 15 minutes of its rays shining on Earth could power the world for a year. Following the invention of the solar collector in 1767, a slow, yet steady evolution of other breakthroughs in the quest include the photovoltaic (PV) effect observed in 1839, manufacture of solar cells in 1883 and a solar-powered communications satellite in 1958. Solar summits in 1973 and 1977 led to the inception of the Solar Energy Research Institute (now the National Renewable Energy Laboratory), part of the U.S. Department of Energy (DOE) Organization Act signed by then-President Jimmy Carter.

Making the most of the “alchemy of sunlight” that Pulitzer Prize-winning author Daniel Yergin writes about in The Prize and The Quest: Energy, Security, and the Remaking of the Modern World has required a global village of inventors, visionaries, scientists and engineers. Pioneering companies have produced technological advancements and reduced manufacturing costs that expand the sun’s services to the world. Today, thanks to solar power, many of the remotest villages in developing countries have electricity.

“Without solar photovoltaics on satellites and those powering the uplink transmitters, downlink receivers and associated equipment on the ground, the isolated residents of developing countries can’t join the modern world,” explains Neville Williams, author of the recently released book, Sun Power.

The founder of the guerilla nonprofit Solar Electric Light Fund (self.org), Williams led the  charge for electrifying households in 12 developing countries in 17 years beginning in 1990, using solar panels and systems funded by grants.“While we were cost-effective and decisive, the results were due to the honest, hardworking and dedicated people we found there,” he advises.

Williams initiated his pioneering advocacy of solar energy as a media specialist with the DOE during the Carter administration and served as the national media director for Greenpeace, in Washington, D.C. In 1997, he co-founded SELCO-India, which managed solar enterprises in India, Sri Lanka, Nepal, South Vietnam and South Africa. In 2005, he founded the solar solutions supplier Standard Solar Inc., of Rockville, Maryland.

Economic Engine

The U.S. currently has an operating capacity of 13,000-plus megawatts of cumulative solar electricity—enough to power more than 2.2 million average American homes. As the industry grows, so does its impact. The Solar Foundation’s Solar Job Census 2013 reported nearly 143,000 solar workers in the U.S.—a 20 percent increase over 2012—at 6,100 businesses in 7,800 locations encompassing every state.

According to Yergin and Williams, the increasing value of nationwide solar installations has “electrified” the U.S. economy. In 2013, domestic solar electric installations were valued at $13.7 billion, compared to $11.5 billion in 2012 and $8.6 billion in 2011. The top 10 states for annual additions of photovoltaic capacity in residential and commercial applications are California, Arizona, New Jersey, North Carolina, Nevada, Massachusetts, Hawaii, Colorado, New York and New Mexico.

Currently, there are more than 550 major solar projects underway nationally. Under the Obama administration, 16 projects have been permitted on federal lands to provide 6,058 megawatts of generating capacity.

The two experts expect solar energy to be a major catalyst of global political and economic change. Williams contends that now is the time to fully access this cheapest form of unlimited energy.

“If millions of poor families in developing countries can get their electricity from the sun, why can’t Americans do the same?” he queries.

In a 2002 National Public Radio Planet Money podcast, Yergin, president of Cambridge Energy Research Associates, in Massachusetts, addressed the concerns of everyone that sees the common sense of relying on solar energy. “Technology will be central to solutions for our energy challenges,” he says. “What needs to be done is very, very large, as are the risks and challenges. What we have going for us is the greatest resource of all—human creativity—and for the first time in history, we are going to see it employed on a global scale.”

Solar Blocks

by Neville Williams

Economics, rather than technological concerns, are now driving the adoption of clean, safe, solar electricity to preserve the environment. During this transition to a new energy paradigm, we can choose to embrace the solar imperative now, rather than later, and prepare for a post-carbon lifestyle without sacrificing our present quality of life.

Many hurdles have been overcome in the shift away from fossil fuels during the past two decades. Challenges still exist, but the hope is that we are on our way toward a brighter future with solar electricity made universally available.

  • GL_1014_SolarInstallerThe cost of solar photovoltaics has dropped 75 percent in the past four years, thanks to China.
  • Solar electricity is now the least expensive energy source in many markets, overcoming for the first time the economic argument that it is too expensive.
  • Innovative partnerships like that formed by green energy provider Viridian with large, full-service solar provider SolarCity lease solar panels to homeowners and businesses that significantly reduce upfront costs. Installation costs, which once averaged more than $20,000, can now amount to just hundreds of dollars.
  • Solar is disrupting the century-old central power generation model, and the challenge is to get the utility industry to change and adopt distributed solar. Utility companies that previously ignored solar energy now fear it might threaten their bottom line if they do not get with the program.
  • While the next big obstacle is energy storage, which allows the use of sun power at night, well-financed new “smart grid” technologies are rapidly emerging.
  • The impending showdown will be between corporate power and people power, comprised of homeowners and businesses producing their own electricity. The politics of energy is central to our national future. The question is, Can we change?
