Tesla's Massive Australian Battery Responds to Coal Power Outages in Milliseconds

Tesla's massive lithium-ion battery storage facility, which was designed to feed South Australia's unstable power grid, is already proving itself by responding to power outages within milliseconds.

The system—the largest of its kind on planet Earth—was tested twice just this month. According to CleanTechnica, on Dec. 14, the Loy Yang coal power plant in the neighboring state of Victoria suddenly went offline. Remarkably, the Hornsdale Power Reserve battery system (the Tesla system's official name) kicked in within 140 milliseconds and injected 100 megawatts of power into the grid.


Two weeks later, another unit of the Loy Yang plant unexpectedly went offline. Tesla battery's also responded within milliseconds to send 16 megawatts to the grid.

“That's a record and the national operators were shocked at how quickly and efficiently the battery was able to deliver this type of energy into the market," State energy minister Tom Koutsantonis commented after the Dec. 14 outage. “Until now, if we got a call to turn on our emergency generators it would take us 10 to 15 minutes to get them fired up and operating which is a record time compared to other generators."

The 100-megawatt Powerpack system, which charges using renewable energy from Neoen's Hornsdale wind farm near Jamestown, is designed to hold enough power for 8,000 homes for 24 hours, or more than 30,000 houses for an hour during a blackout.

Tesla CEO Elon Musk famously made, and won, a bet that his company could build the battery within "100 days from contract signature or it is free." The giant battery officially switched on in early December.

Worldwide Clean Energy Investments Hit $333.5 Billion Last Year

Global investment in renewable energy hit $333.5 billion in 2018, the second-highest on record, according to a new analysis from Bloomberg New Energy Finance (BNEF).

That's a 3 percent jump from 2016 and 7 percent short of the $360 billion record set in 2015.

How Blockchain Could Boost Clean Energy

By Jeremy Deaton

Bitcoin, the much-hyped cryptocurrency, made headlines recently for driving a surge in power use. Around the globe, digital entrepreneurs are 'mining' bitcoins by solving complex math problems, using supercomputers to get the job done. Those supercomputers use a ton of power, which largely comes from coal- and gas-fired power plants spewing gobs of carbon pollution.

But while hackers wreak havoc on the climate, blockchain, the bleeding-edge technology behind bitcoin, could one day help clean up the mess. Climate wonks say blockchain has a role to play in the clean-energy economy, helping homeowners sell electricity, allowing businesses to trade carbon credits, and making it easier for governments to track greenhouse gas emissions.

Post-Fire Landslide Problems Likely to Worsen: What Can Be Done?

By Lee MacDonald

Several weeks after a series of wildfires blackened nearly 500 square miles in Southern California, a large winter storm rolled in from the Pacific. In most places the rainfall was welcomed and did not cause any major flooding from burned or unburned hillslopes.

But in the town of Montecito, a coastal community in Santa Barbara County that lies at the foot of the mountains blackened by the Thomas Fire, a devastating set of sediment-laden flows killed at least 20 people and damaged or destroyed more than 500 homes. In the popular press these flows were termed "mudslides," but with some rocks as large as cars these are more accurately described as hyperconcentrated flows or debris flows, depending on the amount of sediment mixed with the water.

Birders Get a First Look at How 2017 California Wildfires Affected Wildlife

By Matt Blois

A neighbor knocked on Rick Burgess's door at about 9:30 p.m. to tell him a fire was coming towards his home in Ventura, California. When he looked outside he saw a column of smoke, and the hills were already starting to turn orange. He loaded up his truck with a collection of native plants he was using to write a countywide plant guide, and barely had enough time to get out.

Elon Musk's Brother Wants to Bring #RealFood to 100,000 Schools Across America

Kimbal Musk's nonprofit organization, The Kitchen Community, is expanding into a new, national nonprofit called Big Green, to build hundreds of outdoor Learning Garden classrooms across America.

Learning Gardens teach children an understanding of food, healthy eating and garden skills through experiential learning and garden-based education that tie into existing school curriculum, such as math, science and literacy.

Rover Pipeline Spills Another 150,000 Gallons of Drilling Fluid Into Ohio Wetlands

Energy Transfer Partners' troubled $4.2 billion Rover pipeline has spilled nearly 150,000 gallons of drilling fluid into wetlands near the Tuscarawas River in Stark County, Ohio—the same site where it released 2 million gallons in April.

The 713-mile pipeline, which will carry fracked gas across Pennsylvania, West Virginia, Ohio and Michigan and Canada, is currently under construction by the same Dallas-based company that built the controversial Dakota Access pipeline.

Large Dams Fail on Climate Change and Indigenous Rights

Brazil has flooded large swaths of the Amazon for hydro dams, despite opposition from Indigenous Peoples, environmentalists and others. The country gets 70 percent of its electricity from hydropower. Brazil's government had plans to expand development, opening half the Amazon basin to hydro. But a surprising announcement could halt that.

World's Largest Money Manager: Companies Must Respond to Social and Climate Challenges

The world's largest publicly traded companies must take a more active role in solving social issues or face blowback from investors, the CEO of BlackRock said Tuesday.

"To prosper over time, every company must not only deliver financial performance, but also show how it makes a positive contribution to society," Laurence Fink wrote in his annual letter to CEOs of companies in which BlackRock invests. BlackRock is the world's largest money manager, with more than $6 trillion in assets.
