Growing a Solar Forest in a South Carolina Parking Lot

"Solar trees" can turn parking lots into renewable electricity machines.

Parking lots don't have much going for them: they hold cars, sure, but as vast swathes of concrete, they're also part of the urban heat island effect and don't add much to the aesthetics of a neighborhood. In the United States, there are around 160 billion square feet of parking lots. Here's one designer's vision of a better way to use that space—converting it into "solar forests."


California-based Envision Solar created a "solar tree" that can be placed in a parking lot to shade cars and capture sunlight for electricity. Unlike solar panels mounted on roofs, the solar tree can actually turn, depending on the time of day and the season, to absorb the maximum amount of sunshine (and therefore also generate the maximum of power). The trunks of the solar trees can also act as charging stations for electric cars.

Later this year, Envision plans to begin building 2,300 solar trees for a parking lot in South Carolina—enough to generate 35 megawatts of electricity.

This month, challenge a neighbor to GOOD's energy smackdown. Find a neighbor with a household of roughly the same square footage and see who can trim their power bill the most. Throughout February, we'll share ideas and resources for shrinking your household carbon footprint, so join the conversation at good.is/energy.

Sin City is doing something good for its less fortunate citizens as well as those who've broken the law this month. The city of Las Vegas, Nevada will drop any parking ticket fines for those who make a donation to a local food bank.

A parking ticket can cost up to $100 in Las Vegas but the whole thing can be forgiven by bringing in non-perishable food items of equal or greater value to the Parking Services Offices at 500 S. Main Street through December 16.

The program is designed to help the less fortunate during the holidays.

For more than 20 years. Sen. Susan Collins (R-ME) has served the citizens of Maine in the U.S. Senate. For most of that time, she has enjoyed a hard-fought reputation as a moderate Republican who methodically builds bridges and consensus in an era of political polarization. To millions of political observers, she exemplified the best of post-partisan leadership, finding a "third way" through the static of ideological tribalism.

However, all of that has changed since the election of Donald Trump in 2016. Voters in Maine, particularly those who lean left, have run out of patience with Collins and her seeming refusal to stand up to Trump. That frustration peaked with the nomination of Brett Kavanaugh to the Supreme Court.

Fellow member of "the Squad," Ilhan Omar, endorsed him on Wednesday.

The U.K. is trying to reach its goal of net-zero emissions by 2050, but aviation may become the biggest source of greenhouse gas emissions in the U.K. by that same year. A new study commissioned by the Committee on Climate Change (CCC) and conducted at the Imperial College London says that in order for the U.K. to reach its target, aviation can only see a 25% increase, and they've got a very specific recommendation on how to fix it: Curb frequent flyer programs.

Currently, air travel accounts for 2% of global greenhouse gas emissions, however that number is projected to increase for several reasons. There's a growing demand for air travel, yet it's harder to decarbonize aviation. Electric cars are becoming more common. Electric planes, not so much. If things keep on going the way they are, flights in the U.K. should increase by 50%.

Nearly every airline in the world has a frequent flyer program. The programs offer perks, including free flights, if customers get a certain amount of points. According to the study, 70% of all flights from the U.K. are taken by 15% of the population, with many people taking additional (and arguably unnecessary) flights to "maintain their privileged traveler status."
