Tesla Vies to Build World's Largest Battery Again

Tesla has already built the world's largest battery in South Australia, a lightning-fast system that switched on in December and recently saved the energy market millions during an outage.

Now, the Elon Musk-headed venture is vying to build another massive Powerpack system in Colorado for Xcel Energy Inc., an electric utility operating in eight Western and Midwestern states.

Elon Musk: We Must Colonize Mars for Humanity to Survive the 'Dark Ages'

In the event of World War III, the only way for humanity to survive is to colonize Mars or the moon, according to Elon Musk.

"I'm not predicting that we're about to enter the dark ages, but there's some probability that we will, particularly if there's a third world war," the SpaceX and Tesla founder said during a question and answer session at the South by Southwest (SXSW) Conference in Austin on Sunday ahead of President Donald Trump's possible nuclear talks with North Korean leader Kim Jong-un.

Tesla Installing World's Largest Solar Rooftop on Nevada Gigafactory

Tesla has started building a massive rooftop solar array on top of its Gigafactory 1 (GF1) outside Sparks, Nevada.

Once finished, the 70-megawatt system will be the largest in the world by far; the current record-holder is the comparatively shrimpy 11.5-megawatt array in India that can power 8,000 homes.

World's Largest Virtual Power Plant Coming to Australia in Deal With Tesla

South Australia—already home to the world's largest battery—will soon host the world's largest virtual solar plant under a landmark plan from Tesla CEO Elon Musk and the state government.

The plan involves installing a 5-kilowatt solar system and a Tesla Powerwall 2 battery on roughly 50,000 homes across the state over the next four years. The setup will be installed at no charge to the households and financed through the sale of electricity.

Will Shell Turn From Big Oil Into Big Energy?

By Andy Rowell

On the surface, the good times are back for Big Oil. Later this week, Shell is expected to unveil its biggest profits in a decade since the oil price crash.

As the oil price recovers to over $65 a barrel last year, so do Shell's fortunes, with reported earnings of nearly $16 billion.

Battery Storage Revolution Could 'Sound the Death Knell for Fossil Fuels'

If we want to accelerate the world's renewable energy transition, we'll have to modernize the electric grid and we'll need much better batteries. Just look at Germany, which generates so much clean energy on particularly windy and sunny days that electricity prices are often negative.

Sure this is good news for a German person's wallet, but as the New York Times noted, "Germany's power grid, like most others around the world, has not yet adapted to the increasing amounts of renewable energy being produced."

China Leading on World’s Clean Energy Investment, Says Report

By Jocelyn Timperley

China is by far the largest force in global clean energy development and its firms are increasingly looking abroad for opportunities, a new report says.

The report, released Tuesday by the U.S.-based Institute for Energy Economics and Financial Analysis (IEEFA), details the rising importance of China's firms and investors for low-carbon projects outside the country.

2017 Year in Review

As we look back on the most noteworthy environmental stories of 2017, one cannot help but start with the extreme weather that has caused so much destruction to so many around the globe. And with that, the year brought heightened concern for protecting our planet with focused attention on issues like renewable energy, electric vehicles and plastic pollution. And while 2017 was also marked by challenges with the U.S. pulling out of the Paris agreement and making other questionable environmental policy changes, we all enter a new year with the ability to make positive change.

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.
