It's certainly not news anymore that we're entering the "next wave" of cleantech investment. The focus is now on who will ride that wave as it begins to build -- and who will be standing when it crests.
The Global Cleantech 100 report is a good way to judge where investors are thinking about deploying their money.
Each year, the Cleantech Group puts dozens of investors and energy experts together on a panel who then evaluate thousands of early-stage companies based on their level of innovation, their market potential and their ability to penetrate the market. In the end, the panel chooses 100 startups out of the list that they judge as having the most potential.
As it has in previous years, efficiency topped the rankings. This year, however, more than one-quarter of the companies on the list (shown at the bottom of this page) were in the efficiency technologies or services space -- an increase of seven companies since 2012.
"We've seen a huge push up in energy efficiency," said Cleantech Group CEO Sheeraz Haji in an interview. "Solar has by far been the sector hurt the most. That's really illustrative of the broader shift away from capital-intensive upstream solar and toward cleanweb, capital-efficient, software-type deals."
In 2009, there were twenty solar companies -- most upstream -- on the list. This year, there are only six, almost all in the downstream market. Here's a comparison to last year's report:
Not all the efficiency companies are strictly in software and data analytics. There are a few in LED manufacturing, one in waste-heat recovery and some in building materials. But few of them require the heaps of money needed for building out new manufacturing facilities to service an entirely new market.
We can see below that investor sentiment is mostly focused on low-capital opportunities -- even if that means lower potential revenues. That puts efficiency squarely in the sweet spot, as shown in the next chart.
Investors speaking at the Global Cleantech 100 Summit shared this sentiment.
"When you look at the turnover, it's a big shift in the sectoral interest of investors. That really speaks to the vagaries of what's in favor right now," said Rob Day, a partner with Black Coral Capital who frequently writes for GTM about investment trends.
"Vagaries" connotes an arbitrary or inexplicable change in strategy, rather than something planned. The venture capital community is indeed known for having a herd-like mentality, but Day himself has helped Black Coral invest in companies like Noesis Energy and Digital Lumens, two intelligent efficiency companies that are arguably "capital-light."
Speaking to the crowd of investors, Day explained why his firm made a decision to invest in the intelligent LED company Digital Lumens.
"No one wanted to just pay for lighting controls. So they made better LED fixtures with controllability. They took a solutions-based approach and contracted the manufacturing, and they've been able to get good growth with a lot less capital for hardware innovations. There are a lot of companies with stories like that."
The other shift is toward a customer-focused strategy that creates a more compelling case for a product. For example, saving money on energy costs through efficiency measures is an easy proposition on its face. But there are a lot of reasons customers don't buy products or services -- they're worried about risk, they don't like the way a product looks or feels, or they just aren't hearing the right messages that get them to act.
"We're beginning to see a whole new class of company that attracts customers in a different way," said Stephan Dolezalek, managing director of VantagePoint Capital Partners. "Look at Nest -- that's a company that intensely understands what a consumer wants. Companies on the list understand these things in a different way than we did ten years ago."
The exact same trend is playing out in solar. Four out of the six companies that made this year's Global 100 list are providing solutions for downstream deployment: Clean Power Finance, Solar Mosaic, Sungevity and Sunrun.
But there's still skepticism about whether innovation in services will be enough to transform massive quantities of energy infrastructure.
"Many investors are saying that heavy infrastructure was yesterday's model, so they go and do the 'capital-light' stuff. I'm not sure many of the CEOs in this room think that was the right thing to do," said Dolezalek.
There were a lot of nodding heads in the room.
Sheeraz Haji of the Cleantech Group agreed with that sentiment in an interview about the report's rankings.
"I think there's a real risk that we may be overdoing it. The world of cleantech still fundamentally revolves around hard things. I think we have to be careful not to overcorrect," said Haji.
The good thing about this year's list is that the efficiency companies identified are actually making stuff, deploying hardware and delivering services -- not just developing fancy dashboards.
