You might remember the first startup climate tech wave of the early 2000s. Between 2006 and 2011, startups offering solutions to solve the climate crisis received $25 billion in investments. But the Great Recession hit, and the turbulent economy resulted in the failure of many of those startups. However, the 2008 financial crisis wasn’t the only contributing factor to this sudden downturn. The general market just wasn’t ready to welcome sustainable products, which were often expensive. Most customers were choosing more affordable products for commodities such as electricity, especially since the price of solar power was 3x more expensive than coal or gas back in 2009. 

Today, it looks like history could repeat itself. In the last three years, $100 billion has been invested into climate tech startups, creating the second climate tech wave. And in the last few months, the stock market lost a lot of its value — the Nasdaq is down 33.4% and the DOW is down 10.3% year-to-date. Fears of a looming recession remain strong. If that were to happen, would the second climate tech wave crash too?

I can’t see the future, but I know that a lot of things are different in 2022. The increasing demand for greener energy and transportation is supporting the second climate tech wave. For example, solar power is now cheaper than any other energy source. 

The world is also more aware of the climate crisis than it was a decade ago. Following the Paris Agreement — which 34% of the world’s biggest companies have already committed to — corporations and governments alike are aiming to reach net zero emissions by 2050. The U.S. government just passed the Inflation Reduction Act (IRA), the largest climate bill in American history which directly supports climate tech startups. James Wagoner, founder and CEO of Joule Case, a portable and stackable battery startup currently raising online, told us that its clients could be benefiting from a 30% tax rebate on its products thanks to the IRA.

Put simply, whether the economy is healthy in 2023 or not, there’s no better time than now to invest in climate tech. And here are the latest impact startups that began raising capital in November!
