In 2017, the price for high-efficiency solar panels dropped from 72¢/W to 45¢/W, representing a 37 percent decline in cost. The falling price point is driven by several factors, including American consumer demand for higher solar efficiency to compensate for the higher-than-average energy consumption of the average American, as well as Chinese state investment in high-efficiency solar panel production. The shift is also a result of technological change as poly crystalline solar panels switch to mono crystalline, which are at least 10 percent more efficient while only 6 percent more expensive. Meanwhile, the price continues to drop. The primary difference between mono and poly solar panels is the structure by which silicon is shaped and molded into the panel. In mono crystalline solar panels, silicon is formed into bars, then cut into wafers, whereas poly crystalline solar panels are melted together to form wafers. The process to create mono solar panels was invented in 1918. As a result, the earliest solar panels were of the mono crystalline design. However, during an oil crisis-induced burst of solar energy research in the 1970s, an Exxon researcher discovered that poly panels could be manufactured more cheaply.

As 2018 rolls along, some analysts are predicting that this may be the year in which mono crystalline solar panels make up the majority of solar panels manufactured worldwide. The rapidly declining cost of solar energy , even in the face of resistance by the United States government , demonstrates the possibility that a rapid transition to renewable energy may not be as far-fetched as current reality may make it seem.

Comments Off on The Seychelles creates debt-for-conservation deal with Leonardo DiCaprio

The Seychelles, an island nation in East Africa, recently announced the creation of two new Marine Protected Areas roughly as big as Great Britain. It’s part of what The Telegraph called a debt-for- nature swap: the island nation gets a $20 million debt relief plan backed by investors (including the foundation of our favorite eco hero Leonardo DiCaprio ), and in return it will place controls on fishing and tourism industries. In a debt-for- conservation deal designed by The Nature Conservancy , the Seychelles will protect areas covering 81,000 square miles. The move is not without controversy: fishing is limited in areas commercial fishermen and tour operators for years; in some places, like the Aldabra region, people won’t be allowed to fish at all. Tourism has been successful in the Seychelles in recent years, but The Telegraph said record numbers of visitors have taken their toll on the islands; commercial fishing has increased to meet demand. Biodiversity has eroded in the wake of two recent coral bleaching events. The Telegraph said debt restructuring will essentially send Seychelles repayments into a trust set to invest in plans to foster a sustainable blue economy.

They said the Marine Protected Areas will help the nation better prepare for the impacts of sea level rise , warming waters, and ocean acidification . “Without these Marine Protected Areas, activities like oil and gas exploration, deep-sea mining, dredging, and controversial fishing techniques could take place in one of the planet’s most biodiverse oceans with little or no restriction or direction,” the organization said. Today, Seychelles announced two new marine protected areas that equal the size of Great Britain. Join me and @nature_org in congratulating all those who made it happen. https://t.co/OygRCaKY37 — Leonardo DiCaprio (@LeoDiCaprio) February 21, 2018 DiCaprio tweeted the news, along with a link to a Nature Conservancy page where those in support can sign a letter congratulating the citizens of Seychelles. DiCaprio said, “This effort will help the people of Seychelles protect their ocean for future generations, and will serve as a model for future marine conservation projects worldwide. These protections mean that all species living in these waters or migrating through them are now far better shielded from overfishing , pollution, and climate change.” + Nature Conservancy + Congratulate the citizens of Seychelles Via The Telegraph Images via IIP Photo Archive on Flickr , Depositphotos , and Pixabay
