In 1543, Polish astronomer Nicolaus Copernicus published “On the Revolutions of the Celestial Spheres,” in which he challenged the view that the sun revolved around the earth, arguing instead that the earth revolved around the sun. With his new model of the solar system, he began a wide-ranging debate among scientists, theologians, and others. His alternative to the earlier Ptolemaic model, which had the earth at the center of the universe, led to a revolution in thinking, to a new worldview.
Today we need a similar shift in our worldview, in how we think about the relationship between the earth and the economy. The issue now is not which celestial sphere revolves around the other but whether the environment is part of the economy or the economy is part of the environment. Economists see the environment as a subset of the economy. Ecologists, on the other hand, see the economy as a subset of the environment.
Like Ptolemy’s view of the solar system, the economists’ view is confusing efforts to understand our modern world. It has created an economy that is out of sync with the ecosystem on which it depends.

As fossil fuel prices rise, as oil insecurity deepens, and as concerns about climate change cast a shadow over the future of coal, a new energy economy is emerging in the United States. The old energy economy, fueled by oil, coal, and natural gas, is being replaced by one powered by wind, solar, and geothermal energy. The transition is moving at a pace [...]

I had read in Grist on April 15 that Warren Buffett’s Berkshire Hathaway had cancelled six proposed coal plants, but now it seems that opposition to building new coal plants is spreading, among Wall Street investors and the American public. Back in August 2007, 1600 Utahans signed a petition asking Buffett to cut Rocky Mountain Power’s dependence on coal, with the added message that Utahans want their utilities to investigate cleaner energy sources.
The most recent issue of Solar Today includes an article by Lester Brown of the Earth Policy Institute about the public outcry all across American which, in addition to the cost of the plants, has led to the cancellation of hundreds of coal plant construction projects. And a survey conducted by the Opinion Research Corporation, published yesterday, shows that “79% of respondents would prefer to try and meet demand through greater energy-efficiency and conservation before building more coal-fired plants. Only 19% say they disagree.” With that kind of public opposition, it’s not surprising that Wall Street is cooling on coal plants, too.
