Energy & Power Industry UpdateJune 2011

What We’ve Been Reading

page 1

• In his April 2011 commentary, Bill Miller offered a starkly different perspective on oil and

commodity prices than Jeremy Grantham, whom we highlighted last month. Miller writes, “In

the current market, it appears that no matter what happens, it is bullish for oil. If the dollar

weakens, oil goes up because oil is denominated in dollars, and a weaker dollar leads to a

higher oil price. If the U.S. economy slows, that is bullish for oil, because that means the Fed

would continue to pump liquidity into the economy via lower interest rates, and excess

liquidity means higher oil prices. If the U.S. economy strengthens, that is bullish, because it

means more demand for oil. Emerging-market growth is unequivocally bullish for oil, since it

means more demand. Low per-capita use of oil, such as in China, is bullish since it is bound to

go higher. High per-capita use is bullish because it means lots of demand. There is a price at

which demand destruction will begin…which will halt, and then reverse the price. No one

knows what that price is, but it is a lot closer with Brent crude up 50% and West Texas

Intermediate up nearly 40% since early November.” Read his full commentary here.

• EnergyBiz Magazine’s May / June issue focuses on “Nuclear: The Next Act” after what it

terms “a seismic setback” for the industry post-Fukushima. As The New York Times reported,

support for nuclear power plant construction in the U.S. dropped to 43% following Fukushima,

which registered just below the level of a similar poll conducted in 1979 after the accident at

Three Mile Island, though not quite as low as the 34%-level following Chernobyl in 1986.

EnergyBiz argues that it‟s time for the U.S. to rethink nuclear power, and the issue features a

range of interesting perspectives on the topic. The issue was apparently unavailable, or at least

too late to press in Germany, which announced its plan to close all of its nuclear plants by 2022

this past month (see The New York Times’ coverage here).

• The Wall Street Journal featured Matt Ridley‟s “Inconvenient Truths about „Renewable‟

Energy” earlier in the month. Ridley references a recent study from the Intergovernmental

Panel on Climate Change (“IPCC”), which argued that renewable energy sources currently

represent 13.8% of our energy and, if encouraged to grow, could displace our reliance on fossil

fuels. While the headline is encouraging, Ridley notes that 10.2% of the 13.8% share comes

from biomass, namely wood and dung. Wind, solar, geothermal, wave, and tide power account

for just 0.5% of the total. The IPCC includes wood as a renewable resource, but Ridley

correctly notes that it ignores the context of time (e.g., yes, it grows back, but not as fast as it‟s

used). He offers the example of Haiti, which uses charcoal from forests for 60% of its energy.

With 98% of the country‟s tree cover destroyed, Haiti is now burning tree roots for energy. As

Ridley points out, this does not differ greatly from other historical examples of “renewable”

energy sources, such as blue whales or cod. He concludes, “All in all, once you examine it

closely, the idea that "renewable" energy is green and clean looks less like a deduction than a

superstition.” If you have not read it, we recommend Ridley‟s book, The Rational Optimist:

How Prosperity Evolves, which makes the straightforward argument (with plenty of

quantitative and annotated support) that, despite the naysayers, things are getting better.

Industry Observations

LTM Indexed Stock Performance1

Indexed LTM EBITDA Multiples1

• The Infrastructure and Industrial Services, Energy, and Power Stock experienced slight

declines in May in the face of economic headwinds.

• Many commodity prices have exhibited increased instability amidst rising fears of an economic

double-dip and recent economic uncertainty:

– Gasoline, at $2.98 per gallon, has fallen 12.4% since late-April highs.

– Coal prices have continued to rise as energy demand has rebounded along with the

economy.

– The North American Rotary Rig Count is more than double its six year low of 876.
