Tesla Finishes Building World's Largest Battery Month and a Half Ahead of Schedule

Elon Musk has won an audacious bet he made back in March to build a battery system for South Australia in “100 days from contract signature or it is free."

The 100-megawatt Powerpack system is the world's largest, or three times bigger than Tesla and Edison's battery at Mira Loma in Ontario, California.

The Tesla CEO was responding to a challenge from Australian IT billionaire Mike Cannon-Brookes to help fix the Australian state's electricity woes. Losing the bet would have cost Musk "probably $50 million or more."

As it happens, when the grid connection deal was finally signed on Sept. 29—kick-staring the 100-day clock—Tesla was already halfway finished with installation. So if you want to be technical, you could say that the project was finished a month and a half before the contract's deadline. The company originally estimated completion by December 2017.

The lithium-ion battery storage facility will charge using renewable energy from Neoen's Hornsdale wind farm near Jamestown, South Australia and deliver electricity during peak hours.

According to Business Insider, when fully charged, the battery should hold enough power for 8,000 homes for 24 hours, or more than 30,000 houses for an hour during a blackout.

"While others are just talking, we are delivering our energy plan, making South Australia more self-sufficient, and providing back up power and more affordable energy for South Australians this summer," said Premier Jay Weatherill in a media statement.

"The world's largest lithium ion battery will be an important part of our energy mix, and it sends the clearest message that South Australia will be a leader renewable energy with battery storage."

Weatherill said that regulatory testing over the next few days will ensure that the battery is optimized and meets energy market regulatory requirements before operations commence on Dec. 1.

Musk tweeted, "Congratulations to the Tesla crew and South Australian authorities who worked so hard to get this manufactured and installed in record time!"

This College Could Become the First 100% Renewable Campus in U.S.

As a growing number of U.S. cities make pledges towards 100 percent renewables, it's easy to forget that the entire state of Hawaii set this important benchmark three years ago when it mandated that all of its electricity must come from renewable sources no later than 2045.

To help the Aloha State meet this ambitious commitment, in 2015, the University of Hawaii (UH) and the Hawaiian Legislature set a collective goal for the university system to be "net-zero" by Jan. 1, 2035, which means the total amount of energy consumed is equal to the amount of renewable energy created.

Silver Nanoparticles in Clothing Wash Out, May Be Toxic

By Sukalyan Sengupta and Tabish Nawaz

Humans have known since ancient times that silver kills or stops the growth of many microorganisms. Hippocrates, the father of medicine, is said to have used silver preparations for treating ulcers and healing wounds. Until the introduction of antibiotics in the 1940s, colloidal silver (tiny particles suspended in a liquid) was a mainstay for treating burns, infected wounds and ulcers. Silver is still used today in wound dressings, in creams and as a coating on medical devices.

Study Finds Timely Emissions Reductions Could Prevent 153 Million Air Pollution Deaths This Century

One of the roadblocks to swift action on climate change is the human brain's tendency to focus on threats and stimuli that are an obvious and noticeable part of their everyday lives, rather than an abstract and future problem, as Amit Dhir explained in The Decision Lab.

Now, a study published in Nature Climate Change Monday shows that acting quickly to curb greenhouse gas emissions would also reduce the air pollution that is already a major urban killer, thereby saving millions of lives within the next 40 years.

Trump Administration Sells Oil and Gas Leases Near Utah National Monuments

The Interior Department on Tuesday is auctioning off 32 parcels of public lands in southeastern Utah for oil and gas development.

The Bureau of Land Management's (BLM) lease sale includes more than 51,000 acres of land near Bears Ears—the national monument significantly scaled back by the Trump administration last year—as well as the Hovenweep and Canyons of the Ancients monuments.

Katharine Hayhoe Reveals Surprising Ways to Talk About Climate Change

By Katie O'Reilly

Katharine Hayhoe isn't your typical atmospheric scientist. Throughout her career, the evangelical Christian and daughter of missionaries has had to convince many (including her pastor husband) that science and religion need not be at odds when it comes to climate change. Hayhoe, who directs Texas Tech's University's Climate Science Center, is CEO of ATMOS Research, a scientific consulting company, and produces the PBS Kids' web series Global Weirding, rose to national prominence in early 2012 after then-presidential candidate Newt Gingrich dropped her chapter from a book he was editing about the environment. The reason? Hayhoe's arguments affirmed that climate change was no liberal hoax. The Toronto native attracted the fury of Rush Limbaugh, who encouraged his listeners to harass her.

Kinder Morgan Pipeline Protest Grows: Arrests Include a Greenpeace Founder, Juno-Nominated Grandfather

By Andy Rowell

Just because you get older, it doesn't mean you cannot stop taking action for what you believe in. And Monday was a case in point. Two seventy-year-olds, still putting their bodies on the line for environmental justice and indigenous rights.

Early Monday morning, the first seventy-year-old, a grandfather of two, and former nominee for Canada's Juno musical award, slipped into Kinder Morgan's compound at one of its sites for the controversial Trans Mountain pipeline and scaled a tree and then erected a mid-air platform with a hammock up in the air.

The Grapes of Trash

German monk and theologian Martin Luther probably said it best: "Beer is made by men, wine by God." It's true—the world loves its wine. Americans, in fact, downed close to a billion gallons of it in 2016. But winemakers create a lot of waste when they produce all that vino, most of it in seeds, stalks and skins.

Why Mike Pompeo Could Be Even Worse for the Environment Than Rex Tillerson

By Kelle Louaillier

As Secretary of State, Rex Tillerson was one of the most blatant revolving-door cases in the Trump administration and a clear sign that Trump's government was of, by and for the fossil fuel industry. But make no mistake: Mike Pompeo could be far worse.
