The coal industry is in “freefall” worldwide according to the latest annual survey from environmental groups Sierra Club, Greenpeace, and CoalSwarm. According to the survey, new construction and coal plant permits in China and India have sharply dropped off, while aging coal plants were retired across the U.S. and Europe. (The U.S. saw its 250th coal plant retirement on Monday.) The decline of coal has been felt for decades in places like rural West Virginia, and while Trump campaigned on a promise to revive the industry, the survey shows that its decline may be inevitable—while the market share of renewable energy, and potential for sustainable jobs in that sector, continues to rise.

Called the Brooklyn Microgrid, the project is signing up residents and businesses to a virtual trading platform that will allow solar-energy producers to sell excess-electricity credits from their systems to buyers in the group, who may live as close as next door. The project is still in its early stages — it has just 50 participants thus far — but its implications could be far reaching. The idea is to create a kind of virtual, peer-to-peer energy trading system built on blockchain, the database technology that underlies cryptocurrencies like Bitcoin.

The cost of solar energy has dropped 80% since 2009, and wind energy has dropped by 30% in the last three years. This shift means more countries have reached “grid parity” — where the cost of fossil fuels and renewable energy are the same.

Cameron had five flowers installed on the 22-acre Malibu Canyon campus and they generate roughly 300 kilowatt hours per day. The flowers are expected to offset the non-profit school’s power usage between 75-90%. Amazing! The patent-pending design will soon be an available, free and open-source, to encourage wider use of solar power. Now that’s what we call charitable!

Well, here’s one about a different sort of female empowerment—the kind that lights up the night, makes light bulbs shine bright, and literally powers communities. It also features donkeys lugging solar panels around the Kenyan savanna, which is not a sentence I get to write everyday.

Billed as one the largest renewable energy conferences in the world, there were over 4,000 professionals promoting everything from solar energy, to wind power, to biomass, to geothermal, to ocean power, to biofuels and more. The future definately looks bright.
However, with all the choices we have today, less than 7% of our energy consumption is in renewables. Women of green, we need to change that. And change that now.
Fortunately, my guest is on it. She’s a female force helping to move the needle in solar energy. Nancy Hartsoch is a Vice President at SolFocus, a company that developed concentrator photovoltaic technology that allows for low-cost, clean energy that is scalable and dependable.
In my interview with her, we talked the many choices on the market today and what the main deterrents are for ordinary people to get going with renewable energy. This woman is smart. So listen up!
