As social values shifted through the '80s and '90s, as modern conservatism rose to power, and as the electorate became a good deal more skeptical of both government and environmentalists, these strategies, and the institutions that were created to prosecute them, foundered.

Environmentalism has become a special interest, incapable of addressing large, complex, and global problems such as global warming.

The great successes of the modern environmental movement in the '60s and '70s had laid the seeds of their failure in the early years of the 21st Century. They had built institutions filled with lawyers and scientists well suited to lobby policy makers who basically shared their world view. This worked well when liberals controlled the Congress and much of the federal bureaucracy, and when the politics of the time were more supportive of active government efforts to regulate the economy and clean up the environment.

Skepticism about the potential to achieve the kinds of breakthroughs we need has been a self-fulfilling prophecy.

In the months after George W. Bush's reelection, a lot of liberals and environmentalists were ready to take a hard look at their political agenda, the Democratic Party, and the interest groups they supported.

It is worth noting that virtually every alternative energy source we have - solar, wind, nuclear, and battery and fuel cell technologies for storage - resulted from public innovation and R&D, not private. The problem is that we haven't done enough of it, and we have done it inconsistently.

We don't make the investments we need to make, the sector fails to innovate, and then we conclude that it can't innovate.
