In our latest Clean Energy Trends 2010 report, we found reasons for the clean-energy sector to be hopeful. At the same time, we found a number of not-so-insignificant question marks surrounding the future of clean energy. These include the rise of China as a clean-tech leader and what it means for other nations; the current lack of reliable and sustainable financing for technology and project development and the need for new innovative financing models like "green banks;" and the issue of when and if initial public offering (IPO) markets will return so that early-stage investors have a viable "exit" strategy for their portfolio companies.
Before we delve into these issues, let’s look at the latest numbers from our report. In 2009, combined global revenue for the three major clean-energy sectors – solar photovoltaics (PV), wind power, and biofuels – grew by 11.4 percent over 2008, reaching $139.1 billion. These three sectors are expected to reach $325.9 billion by 2019, according to Clean Edge research and analysis. Indeed, following one of the worst years in economic history, signs of hope have begun to emerge for the clean-tech sector, with clean energy becoming a driving force for global economic recovery from Beijing to Seoul, and Washington D.C. to Brussels.
Additional findings include:
But as mentioned above, a host of challenges are present at both the micro and macro levels. Perhaps the most notable is the rise of China as a clean-tech powerhouse. Last month the Pew Charitable Trusts released a new report that echoed the findings in our Clean Energy Trends report: that China is now leading the world in the race to dominate clean energy. The Pew Report finds that in 2009, China took the top spot in spending on clean energy for the first time, pushing the U.S. into second place. China also now leads the world in manufacturing solar PV and installing new wind turbines. In our report, we make it clear that while China is a formidable opponent, it's too early to declare the country the de facto winner. No one country or region will likely lead in all clean-energy sectors and China still faces significant pollution issues and free flow of information constraints (witness Google’s recent departure from China in March) that could stand in the way of true clean-energy leadership.
Another major issue facing the clean-tech sector during the Great Recession is access to capital – in particular for project development. In the U.S., we believe that at the state and federal level, we need new financing models to bridge this gap. One of the most interesting emerging ideas is the creation of a Green Bank at the federal level, or green banks scattered across the nation at the state level. Other ideas, some of which we highlighted in our recent Five Emerging U.S. Public Finance Models report, are clean-energy victory bonds, revolving loan funds, and investment tax credits and grants. But whatever the combination of public and private investment vehicles, we need to overcome the current dearth of financing options.
One of the other big threats to the expansion and growth of clean tech is the dearth of viable exit strategies for clean-tech companies. The exit strategy of choice for successful startups is an IPO. But as we explain in Clean Energy Trends 2010, IPOs in the U.S. continued at historic lows, with just 13 venture-backed IPOs in 2009 (up only slightly from a meager six venture-backed IPOs in 2008), according to Thomson Reuters and the National Venture Capital Association. And while U.S. clean-energy venture activity continues to expand – clean energy represented 12.5 percent of total U.S. venture activity in 2009, representing the largest share in the history of the clean-energy asset class – the limited number of IPOs remains an obstacle to continued expansion.
Next year, we’ll issue our annual Clean Energy Trends report again in mid March. We’ll get to see how some of the developments and issues we outlined this year panned out, how the market performed year-over-year, and where we see things headed. Stay tuned. These are, by any measure, interesting times we live in.
