Tesla, SolarCity Power Entire Island With Solar + Batteries
Ta'u, an island in American Samoa, has turned its nose at fossil fuels and is now almost 100 percent powered with solar panels and batteries thanks to technology from the newly combined Tesla and SolarCity.
The microgrid is operated by American Samoa Power Authority and was funded by the American Samoa Economic Development Authority, the U.S. Environmental Protection Agency and the Department of Interior.
Radio New Zealand reported that the $8 million project will significantly reduce fuel costs for the island, which is located more than 4,000 miles from the west coast of the U.S. Ta'u's 600 residents previously relied on shipments of diesel for power. At times, a shipment could not arrive on the island for months, meaning the island had to power ration and faced reoccurring outages.
But the new microgrid replaces this reliance on dirty fuels with more affordable solar energy, as Peter Rive, SolarCity co-founder and CTO, detailed in a blog post about the project, adding that the microgrid is designed to optimize system performance and maximize savings.
"Factoring in the escalating cost of fuel, along with transporting such mass quantities to the small island, the financial impact is substantial," Rive wrote. He pointed out that the microgrid also eliminates "the hazards of power intermittency" and makes "outages a thing of the past."
The microgrid, which only took one year to build, features 1.4 megawatts of solar generation capacity (or 5,328 solar panels) and 6 megawatt hours of battery storage from 60 Tesla Powerpacks. An estimated 109,500 gallons of diesel will be offset per year.
"Before today, every time we turned on the light, turn on the television, turn on maybe the air conditioner, all of the cash registers in China, Vietnam, Saudi Arabia go 'cha-ching,' but not after today," SolarCity market development director Jon Yoshimura told Radio New Zealand. "We will keep more of that money here, where it belongs."
With the Powerpacks, the island can store solar energy at night, allowing for around-the-clock use. The microgrid allows the island to stay fully powered for three days without sunlight and can recharge to full capacity in only seven hours.
A hospital, high school and elementary schools, fire and police stations and businesses will be using the new clean energy source.
"It's always sunny out here, and harvesting that energy from the sun will make me sleep a lot more comfortably at night, just knowing I'll be able to serve my customers," local resident and business owner Keith Ahsoon told SolarCity.
"This is part of making history," Ahsoon added. "This project will help lessen the carbon footprint of the world. Living on an island, you experience global warming firsthand. Beach erosions and other noticeable changes are a part of life here. It's a serious problem, and this project will hopefully set a good example for everyone else to follow."
"Ta'u is not a postcard from the future, it's a snapshot of what is possible right now," Rive wrote. "Renewable power is an economical, practical solution for a growing number of locations and energy needs, and islands that have traditionally relied on fossil fuels can easily transition to microgrids powered by solar and storage today."

‘Companies Should Not Be Allowed to Use Hazardous Ingredients in Products People Use’: Michelle Pfeiffer Speaks Up for Safer Cosmetics
The beauty products we put on our skin can have important consequences for our health. Just this March, the U.S. Food and Drug Administration (FDA) warned that some Claire's cosmetics had tested positive for asbestos. But the FDA could only issue a warning, not a recall, because current law does not empower the agency to do so.
Michelle Pfeiffer wants to change that.
The actress and Environmental Working Group (EWG) board member was spotted on Capitol Hill Thursday lobbying lawmakers on behalf of a bill that would increase oversight of the cosmetics industry, The Washington Post reported.

Scientists at the United Nations' intergovernmental body focusing on biodiversity sounded alarms earlier this month with its report on the looming potential extinction of one million species — but few heard their calls, according to a German newspaper report.
The climate crisis is a major concern for American voters with nearly 40 percent reporting the issue will help determine how they cast their ballots in the upcoming 2020 presidential election, according to a report compiled by the Yale Program on Climate Change Communication.
Of more than 1,000 registered voters surveyed on global warming, climate and energy policies, as well as personal and collective action, 38 percent said that a candidate's position on climate change is "very important" when it comes to determining who will win their vote. Overall, democratic candidates are under more pressure to provide green solutions as part of their campaign promises with 64 percent of Democrat voters saying they prioritize the issue compared with just 34 percent of Independents and 12 percent of Republicans.
President Donald Trump has agreed to sign a $19.1 billion disaster relief bill that will help Americans still recovering from the flooding, hurricanes and wildfires that have devastated parts of the country in the past two years. Senate Republicans said they struck a deal with the president to approve the measure, despite the fact that it did not include the funding he wanted for the U.S.-Mexican border, CNN reported.
"The U.S. Senate has just approved a 19 Billion Dollar Disaster Relief Bill, with my total approval. Great!" the president tweeted Thursday.
