Who Has the Best Mix of Technology, Policy and Capital?
Clean Edge, a research and advisory firm operating in the cleantech sector, has compiled a top 10 of the U.S. states showing the most "clean energy leadership" based on 80 different state-level indicators and more than 4,000 public and private data points across all 50 states. This isn't just about which state has the biggest share of its energy produced by clean sources, or which state built the most clean energy capacity in the past year. They also take into account things like government policies, venture capital, patent activity, etc, and they adjust for state size. So who made the top 10 and who came out on top? Read on.

California comes out ahead by a pretty wide margin (look at the scores!). According to Clean Edge, this is because it is "everaging its history of technology innovation, rich bounty of natural renewable energy resources and investment capital, and consistently supportive government policies."

Some more notable facts:

-- California leads in the technology and capital categories, but the #1 state for policy is Washington - just ahead of Massachusetts, which ranks first in regulations and mandates, and Illinois, the top state for incentives.

-- Iowa is the nation's leader in utility-scale clean electricity generation as a percentage of total electricity, receiving more than 14 percent of its in-state generation in 2009 from wind power. No other state exceeded 10 percent electricity from large-scale clean- energy sources.

-- California-based companies accounted for nearly 60 percent of all U.S. venture capital investments in clean energy in 2009, but Massachusetts led in VC investments per capita.

-- Michigan, with its recent focus on electric vehicle and automotive battery technologies, is the #1 state for clean-energy patents - a key indicator in the human & intellectual capital area of the Index's capital category.
