Climate tech is back—and this time, it can’t afford to fail
MIT Technology Review
Our in-depth reporting on innovation reveals and explains what’s happening now to help you know what’s coming next.
Climate tech is back, baby. A little over 10 years ago, a cleantech bust left almost all the renewable-energy startups in the US either dead or hanging by a thread. Now, the excitement around climate tech investments and manufacturing is back, and the money is flowing again. In this edition of What’s Next in Tech, understand why cleantech investments are flourishing once again, and why we desperately need these technologies to succeed now more than ever.

A decade after the high profile bust of cleantech 1.0, venture-backed firms are again flourishing. We need them to succeed.
Over the past few years, there has been a huge increase in public and private spending, both in the US and elsewhere, on technologies and infrastructure to address climate change. A recent analysis estimates that total green investments reached $213 billion in the US during the 12 months beginning July, 2022. Most of that spending is allocated to building sources of renewable energy, such as wind or solar, as well as to supporting battery and EV manufacturing and creating green hydrogen infrastructure.
We’ve been here before. Kind of. A surge in cleantech investments, which began in 2006 with the high-profile entry of some of Silicon Valley’s leading venture capitalists, lasted for a few years. But by the end of 2011, almost all the renewable-energy startups in the US were dead or struggling to survive.?
As spending on cleantech dwindled to miserly levels, consumer-facing software-based businesses, like Airbnb and Uber, took off. The common wisdom was that advances based on science and engineering in cleantech were too expensive and risky to scale up. The proportion of venture capital going to cleantech dropped from more than 8% in 2008 to around 3% between 2016 and 2020.??

Things are a little bit different now. VCs are no longer going it alone. Cleantech 2.0 investors include hedge funds, corporations, growth investors, and even wealthy individuals. And today, the stakes are clear. We can’t afford to fail again. We desperately need these new advances to succeed. Will they? Read the story.

11 个月One gallon of jet fuel or gasoline weighs about 6lbs. How hundreds of pounds of batteries does it take to replace that much concentrated energy? When the petroleum energy is expended….it doesn’t leave hundreds of pounds of batteries, that are an environmental hazard. The point being is, some CO2 is less of environmental hazard than toxic batteries, they rely on natural gas and petroleum products to be charged. The cleanest energy source is Nuclear. Which is practical for transportation systems, but totally reliable for the electric grid. France produces over 60% of its electricity from Nuclear power. Why is the USA far behind France?
Encouraging news re: climate tech. What many fail to appreciate is that global warming will continue even if we stopped all greenhouse gas production today. We need both alternative renewable sources AND atmospheric extraction to stop that trajectory. In the meantime, the moral hazard of assuming progress in alternative energy is sufficient to stop warming and encouraging some (including the host Sultan of COPP) to ignore the devastating hazards of continued fossil fuel consumption.
