Today, the company is announcing a new milestone: Since 2015, it has installed a worldwide total of a gigawatt-hour of energy storage–technology that is critical for using renewable energy at scale. For comparison, that’s nearly half of the entire amount of energy storage installed globally last year.

The cost of battery storage keeps falling; between 2010 and 2016, the price across the industry fell 73%, from $1,000 a kilowatt-hour to $273 a kilowatt-hour. By 2020, it may drop to $145 a kilowatt-hour, and by 2025, to $69.5 a kilowatt-hour.

The growth is only a fraction of what’s needed to transform energy. In 2015, when Elon Musk talked about the company’s new energy division, he estimated that it would take 2 billion Powerpacks to fulfill the world’s energy needs. “Even at 300%, we’ll need to grow it this way for decades, frankly, to really solve the problem,” says Straubel. “And not just us, but other companies need to get involved, too.”

Lots of high-minded technological thinkers, particularly Elon Musk, have proposed a universal basic income, a form of wealth distribution that ensures every citizen receives a baseline income whether or not they are employed, as a likely solution to the problem of workforce automation. But the White House report takes a more somber approach, describing a basic income as “giving up on the possibility of workers’ remaining employed.” Instead, the report suggests a number of policy proposals (like Obama’s national free community college initiative, and expanded unemployment benefits) as ways of actively facilitating the transition into a more AI driven economy.
