Solar cells and green holiday celebrations

Dear EarthTalk: What’s the latest in cutting-edge, hyper-efficient solar cells? Are we really moving beyond huge photovoltaic panels anytime soon?

Michael Williams

Many people still consider environmentalists’ favorite black panels as the cutting edge of renewable energy. However, the burgeoning solar industry has spent the last four decades refining these original photovoltaic panels, giving way to an entirely new generation of solar technology.

Most of us could hardly recognize some of the new solar collectors. Researchers at Michigan State University specifically responded to the aesthetic critics of solar panels by creating transparent solar cells. Well, not totally transparent--they actually have thin strips of traditional solar panels to convert the infrared light being reflected by the entire panel. This technology could effectively turn any sheet of glass into a solar energy producer, from the windows of your office building to the screen of your cell phone.

This could spell the end for space-intensive solar plants. Currently the cells cannot convert light into electricity at efficient enough levels to be productive, but researchers hope to achieve efficiency closer to that of existing photovoltaic panels in coming years. Though less effective than older technology, the sheer scale of utility of the new model makes it a much more substantial potential energy source.

Beyond the collection of solar energy, storage continues to be a problem. Modern batteries are typically inefficient and expensive, making solar energy only useful during daylight hours. Researchers at Ohio State University are working to solve this problem and recently debuted a photovoltaic panel with a built-in battery. If the new design is successful, fusing the battery and panel into one could be a game-changer. The design has already shown to make batteries 20 percent more efficient and 25 percent less expensive.

Another area of solar innovation has been ingenuity of application. Thinking outside the box has helped establish potential ways to industrialize the production of solar energy without consuming an excessive amount of acreage in the process. The Dutch have already pioneered solar roadways, in which highways are lined with solar panels. This saves clearing more land and makes use of land that is otherwise entirely unproductive. Another effort to limit land use involves constructing solar plants in the 70 percent of the planet that is covered by water. Experiments have already begun in France, England, India and California. 

And while seemingly far-fetched, generating solar power from space is another area being examined. Satellites could capture significantly more sunlight than earthbound panels, as they could be positioned to collect solar radiation all the time. The first proposal and tests of this idea began over 40 years ago. The challenge is to create satellites that can capture sunlight, convert it to microwave energy, and beam it back to Earth. The exciting potential of this idea has led to large-scale investment by India, China and Japan. 

No doubt we are only at the beginning of the age of alternative renewable energy, and the next few years and decades will be an exciting time to follow the growth of solar power from a fringe sector to a dominant player in the global energy mix.

 

Dear Earthtalk: The holidays can be so wasteful. What are some ways we can green our celebrations this year?

Belinda McHugh

Los Angeles, Calif.

 

Sipping eggnog, listening to carols by the fire and enjoying the beauty of colorfully decorated homes are all warm memories the holiday season conjures. Yet with the rising popularity of Black Friday and Cyber Monday, millions of people are now increasingly absorbed in the season’s commercialism. The National Retail Federation estimates that holiday sales this year will add up to $630.5 billion. All of this shopping generates a lot of trash. According to the U.S. Environmental Protection Agency (EPA), Americans throw away approximately one million extra tons of trash between Thanksgiving and New Year’s Day.

“Simplify the Holidays,” an e-booklet from the Center for a New American Dream (CNAD), reports that nine in 10 Americans believe holidays should be more about family and caring for others, not giving and receiving gifts, yet the average U.S. consumer plans to spend more this year — about $805 — on holiday shopping than last year. To help provide meaningful ways to have fun with less stuff this season, “Simplify the Holidays” includes ideas for simple gifts, low-waste wrapping, ways to connect with your children during the holidays, and more. Readers are asked to “consider creating holidays that instill more meaning into the season and encourage more sharing, laughter, creativity and personal renewal.”

“It’s not about depriving yourself of things during the holiday season,” Wen Lee, director of online media and engagement with CNAD, emphasizes. “It’s about refocusing on things that really matter, and reducing stress.”

Additional easy, stress-free ways to respect the environment during the holidays include carrying reusable totes when shopping for gifts, and using LED lights, which last 20-30 years and require 1/50th the electricity of conventional lights for decorating your tree or home. According to CalRecycle, the 2.6 billion holiday cards sold each year could fill a football field 10 stories high—fortunately, the multitude of e-cards available on the web today provide a no-waste alternative.

Further, the 33 million Christmas trees the U.S. Environmental Protection Agency (EPA) estimates are sold in North America each year don’t have to end up in landfills — some areas have recycling programs that turn Christmas trees into wood chips and mulch, and some companies will home-deliver full-size, potted live trees and pick them up after New Year’s and re-plant them. And with nearly 60 percent of Americans admitting they receive unwanted gifts during the holidays, asking friends and family what gifts they really need or want is an easy way to save waste and minimize time-consuming returns.

Greening your holiday season certainly helps the environment, but research shows it is also good for personal and family well-being. The 2002 study, “What Makes for a Merry Christmas?” by psychologists Tim Kasser and Kennon Sheldon concluded that “family and religion provided the greatest benefit to holiday well-being.”  Kasser recently told the American Psychological Association (APA): “[Our study] found that to the extent people focused their holiday season around materialistic aims like spending and receiving, the less they were focused on spiritual aims…we also found people reported ‘merrier’ Christmases when spirituality was a large part of their holiday, but reported lower Christmas well-being to the extent that the holiday was dominated by materialistic aspects.”

When designer Abigail Horace joined the Blackshires Leadership Accelerator, she was looking for support for her business, Casa Marcelo, which was founded in Salisbury in 2019. Through the Accelerator, she created the Black Berkshires Social Club, which creates culturally grounded social spaces for Black and BIPOC residents in the region. Throughout her experience, Horace found a community of peers invested in one another’s success.

“Finding Blackshires has been transformative,” Horace said. “Being a BIPOC founder in this region can feel isolating, and this community has changed that. They see my work, champion my business and have opened doors I couldn’t have opened alone.”
