A U.S. investment boom in clean energy technology will likely go better the second time around, according to a new analysis led by Stanford University.
Venture capital investments in clean energy – or cleantech – startups peaked in 2008 and have been mired in a slump the past seven years, despite a 10-year bull market for almost all other U.S. investment sectors. When funds dried up, a generation of companies merged, shut down or sold cheaply. The lessons learned from that cycle by investors, government policymakers and entrepreneurs will help when cleantech investing rebounds, according to the researchers.
“The next cycle will be much more productive,” said Stanford professor of management science and engineering, John Weyant, who co-authored the new book, Renewed Energy: Insights for Clean Energy's Future, outlining the findings. “It has to be. The prerequisites for making the world’s energy sustainable, affordable and reliable is technological innovation and rapid deployment of the fruit of those efforts.”

Weyant and his co-authors drew their conclusions from in-depth interviews with 11 thought leaders in the energy sector, such as John Woolard, who led startups Silicon Energy and BrightSource Energy; Tom Baruch, the founder of CMEA Capital; Carol Browner, former head of the U.S. Environmental Protection Agency; and Steven Chu, former U.S. Secretary of Energy and now Stanford professor of physics and of physiology.
A commonly held idea is that the main problem with cleantech was that new energy technologies require much more time and money to develop than do IT startups, with which the investors had so much success.
The new analysis dives deeper. Cleantech startup founders and employees usually had extensive experience in areas like inventing new materials and devices, but they often utterly lacked experience in manufacturing or operating a business, the researchers find. A similar lack of experience was not necessarily fatal for IT startups, because they often were creating new markets, whereas clean energy ventures are trying to capture a share of an existing market.
“The oil companies and utilities that the startups seek to displace are very well-tuned operations,” said co-author Ernestine Fu, BS ’13, MS ’13, MBA ’16, an investor at venture capital firm Alsop Louie Partners. “The good news for cleantech is that an increasing number of managers from traditional energy companies now work at startups, providing much needed knowledge.”
The researchers and the people they interviewed agree that fund managers should not invest in startups that are not ready for commercialization, but they disagree on which types of funds will get the cleantech ball rolling again. Baruch advises that smaller funds should avoid cleantech, because they do not have sufficient capital to survive energy’s long development cycle.
However, Susan Preston, founding general partner of the California Clean Energy Fund’s angel investments, thinks venture capital for cleantech will remain minimal for at least a few more years. Instead, she says, angel investors through typically modest stakes will reinvigorate the market over the next decade.
The role of government
“Today’s cleantech industry is like the early days of ocean exploration,” said Fu. “The monarchs sponsored the early expeditions, which were expensive, very risky and potentially highly profitable. By doing so, they created new trade routes and new markets, and after a while, trading companies and the rest of the private sector took over. The original investments paid huge dividends to their countries.”
In cleantech today, governments should not make venture-style investments in companies that are fairly advanced, according to the book’s consensus. Instead, if the government wants to spur cleantech, public funds should go to research and development of technologies too speculative for the private sector to sponsor. These dollars should be relatively small and spread out among many promising technologies.
The people interviewed also agree that good public policy is key to developing sustainable energy, and they offer a wide variety of policy prescriptions that would help build the market and infrastructure:
As these policies create demand and technologies develop, the cleantech investors can identify strong teams to support.
“Investors can identify talented, bold entrepreneurs in a way that government cannot and should not,” said the third co-author, Justin Bowersock, founder of Rockhill Advisors and a former researcher with Stanford’s Steyer-Taylor Center for Energy Policy & Finance. “An early investment is often a bet on the founder and the team as much as on the technology. This involves a lot of intuition and pattern matching from past experience. No government policy can replicate this process.”
After setting clear goals and ground rules, government should leave the private sector as much flexibility as possible, suggests former EPA chief Browner.
For entrepreneurs, Baruch advises that trying to make energy cheaper is a losing battle for solar companies. Instead, successful U.S. solar companies today are those that provide solar services and finance, rather than manufacture panels. Woolard says that entrepreneurs should first learn what the market wants before developing a new technology.
