The slow moving Senate debate over climate change offers an opportunity to revisit the fundamentals of climate change. While the physical science about natural and anthropogenic forcings is the place to start, the economics of climate change is highly relevant for the policy debate. In this regard,  a perfectly timed literature review in the Spring 2009 The Journal of Economic Perspectives is worth studying.

There have been 13 – count them, 13 – studies published in the peer reviewed literature that have wrestled with the economic implications of a doubling of atmospheric greenhouse gases (GhGs) on a CO2-equivalent basis.  Those 13 studies have yielded 14 estimates of what will subsequently happen to global GDP.  For those who are curious, 10 of those studies assume a subsequent warming of 2.5 C; two assume that a 1 C warming would follow; and two assume a 3 C warming would follow. …

[After publication of my New York Times Op-ed on peak oil, Joseph Romm posted a response—and a challenge—on his website, and later expanded it on The Huffington Post. Below is Michael Lynch’s response.]

Thank you very much for your invitation to a wager on the price of oil, Joe, which I take to be serious, even though you made no effort to convey the wager to me personally. (If you were simply making a “‘pr” effort, feel free to withdraw it.) I would warn you that for most of my career I have been referred to as a ‘heretic’ or ‘contrarian’ and have repeatedly outperformed other forecasters by explaining (in a number of academic publications) why the forecasting of oil price and supply has been so deficient. That you appear to have been more prescient than me no doubt gives you confidence.…

Renewable energy generates a larger portion of the world’s electricity each year. But in relative terms, solar power generation is hardly a blip on the energy screen despite its long history of technological development. Solar-generated electricity has one major advantage over it’s more ubiquitous cousin wind power: electricity is generated during typical peak demand hours making this option attractive to utilities that value solar electricity for peak shaving. However, the capital cost of all the solar technologies are about $5,000/kW and higher and projects are moving forward only in particular regions within the U.S. with tough RPS requirements and subsidies from states and the federal government.

In Part I, we reviewed the enormous scale and capital cost considerations of photovoltaic projects and then introduced the standard taxonomy of central solar power generating plants.…

Editor’s note:  This article is the second of two on shale gas production.  The first dealt with the U.S. situation; this one looks at the potential impacts of shale gas production in Europe and China.

Natural gas production in Europe, currently just over 11 Tcf, has been falling rapidly over the past decade.   About three fourths of Europe’s gas is produced in just three countries: the UK, Norway and the Netherlands.  Production peaked in 2003 at 13.5 tcf.

Consumption, on the other hand, continues to rise.  Gas use in Europe stood at 20.5 tcf in 2008 and is likely to increase further as coal-fired power plants retire or are phased out of service for environmental reasons.  Most of Europe’s imported gas comes from Russia (about 80%), with the remainder mostly as LNG.…
