Some Cautionary Thoughts about Wind

This story has been edited to make it clearer that the analysis relates to US wind rather than European wind and to clarify the problem with excess generation at night. I also added an Item 10.

I think we think we know more about wind-power than we do. These are a few things that I have recently discovered about wind that make me think that plunging headlong into electricity is not necessarily a good idea. At this point, we don't seem to have a plan that does much more than address wind turbines themselves.

I should make it clear that this discussion relates to US wind power, not European wind power. Many of the issues directly or indirectly relate to the fact the US is facing a multi-faceted problem--lack of wind turbines, needed grid upgrades, and lack of electrical storage. In a time of financial problems, the price of such a big change makes it difficult to tackle all these problems on the necessary scale at once. If we only add wind turbines, and make minimal upgrades in storage and transmission, the change is still likely to still be expensive and will likely leave us with the need for large subsidies. Without extensive grid upgrades and electrical storage changes, wind generated electricity will continue to play only a supporting role, acting mostly as a fuel substitute.

Europe has been dealing with this issue longer and has better addressed the wind transmission and storage issue, so it is in better shape in this regard. Jerome Guillet has prepared a write-up focusing more on the European perspective.

The cost of wind, the price of wind, the value of wind

I'd like to try to clear some of the confusion that surrounds the economics of wind power, as it is often fed and used by the opponents of wind to dismiss it. As I noted recently, even the basic economics of energy markets are often wilfully misunderstood by commentators, so it's worth going in more detail through concepts like levelised cost and marginal cost, and identify how different electricity producers have different impacts on electricity (market) prices (which may or may not be reflected in retail prices) and have different externalities. Value for society of a generation source may also include other items that are harder to acount in purely monetary terms (and/or whose very value may be disputed), such as the long term risk of depletion of the fuel, or energy security issues, such as dependency on unstable and/or unfriendly foreign countries or vulnerable infrastructure.

Depending on which concept you favor, your preferred energy policies will be rather different. Follow me below the fold for a tour.

Some Thoughts on the Obama Energy Agenda from the Perspective of Net Energy

The Obama-Biden comprehensive a New Energy for America Plan is designed to:

  1. Help create five million new jobs by strategically investing $150 billion over the next ten years to catalyze private efforts to build a clean energy future.
  2. Within 10 years save more oil than we currently import from the Middle East and Venezuela combined.
  3. Put 1 million Plug-In Hybrid cars -- cars that can get up to 150 miles per gallon -- on the road by 2015, cars that we will work to make sure are built here in America.
  4. Ensure 10 percent of our electricity comes from renewable sources by 2012, and 25 percent by 2025.
  5. Implement an economy-wide cap-and-trade program to reduce greenhouse gas emissions 80 percent by 2050

The Obama energy agenda focuses on - and these are not mutually exclusive - efficiency, electrification, and the promotion of alternative energy resources. Its five main goals are set up in a way so that success in any one of the five individual areas will reinforce the other 4, helping the overall agenda achieve success. For example, creating 25% of the U.S. electricity production from renewable resources (goal #4) will aid in decreasing the U.S. greenhouse gas emissions by 80% (goal #5).

The energy agenda is a welcomed change showing a future outlook that is based, at least to some [small] extent, on the physical realities of the natural resource world. However, from the perspective of net energy, some potential problems do exist. My goal here is to discuss some possible shortcomings of the new administrations energy agenda from the perspective of net energy.

Wind power set to decline under Obama?

For the fourth consecutive year, the US set records in 2008 for the construction of new wind farms, with more than 8,300MW installed in the year, making the country the leader for both yearly installations and, for the first time in many years, overall installed capacity (nudging out Germany which has long been the world leader). The sector created a record number of jobs at a time when few other sectors did.

But for reasons linked to the inconsistent regulatory framework until now, and to the ongoing credit crisis, 2009 is likely to be a bad year for wind, with a decline in installations and, possibly, layoffs.

Of course, Obama is not to blame for that situation, which he inherits, but it will be a pretty bad signal to see wind power decline significantly this year - and it would be an inexcusable one if that decline continues into 2010. The current stimulus plan does include measures to support the industry, but these seem oddly unambitious given the context of economic crisis and wind's proven ability to create jobs and economic activity, to provide cheap power and to eliminate both carbon emissions and fossil fuel imports.

Advice to Pres. Obama (#5): One Engineer's Advice for Energy Policy

This article is one of a series of articles, offering energy advice to President Obama and his administration.

The incoming Obama administration has promised a much-needed change in the direction of US energy policy (or non-policy, as some see the current situation).  However, some of those changes appear to be campaign gimmicks or aimed at satisfying special interests rather than solving our various problems.  (The heavy-for-light crude swap in the Strategic Petroleum Reserve proposed in the Obama-Biden energy proposal appears to be one such gimmick.)

For much too long, US energy legislation (I hesitate to call it policy, because it lacks the coherence to justify the label) has been aimed at short-term patches on problems which have only gotten worse.  CAFE regulations have barely held fuel economy steady, while low fuel prices caused consumption to skyrocket.  "Free trade" allowed cheap oil imports to kill movement toward efficiency and substitutes.  The auto industry lobbied against fuel taxes to promote its short-term interest in selling profitable trucks, with the long-term result that all 3 US automakers will go bankrupt in the next year if nothing is done.

We've had change before, but the results put us where we are now.  It's time for the right change. 

Advice to Pres. Obama (# 4): Go for Wind Power, Seriously

There is no silver bullet to either the financial crisis, the economic crisis, the housing crisis, the industrial crisis, the jobs crisis or the energy crisis we're in right now. But there is one sector of activity which can help in every single one of these: wind power.

US Energy Tax: How Level Is the Playing Field?

A new study has been issued by the Manhattan Institute, called TAXING ENERGY IN THE UNITED STATES: Which Fuels Does the Tax Code Favor? The study was written by Gilbert Metcalf of Tufts University. I also participated in a conference call with Metcalf regarding the report. A couple of Metcalf's findings:

• The tax code is not at all generous with respect to investments in the electric grid. The effective tax rate on these investments is very close to the unadjusted statutory tax rate of about 39%. If investment is to be encouraged in the electric grid, Dr. Metcalf believes that this tax rate must be lowered.

• The current tax code, especially since enactment of the Energy Policy Act of 2005, strongly encourages investment in nuclear, wind, and solar power, which enjoy tax subsidies ranging from nearly 100 percent, for nuclear, to more than 200 percent, for solar. In other words, tax subsidies for these forms of energy generation are sufficiently generous that investors may use them to offset tax liabilities for capital gains and income derived from non-energy investments. The telephone discussion indicated that these provisions are not currently working as intended for wind and solar, because of lack of "tax appetite".

How to keep on financing wind farms when banks have no money left.

My earlier wind diaries can all be found here: Wind power series

Banks are engaged in a massive deleveraging exercise right now. One part of that has been much described and commented upon: the elimination of bad assets, either by taking the losses or by dumping them on the tax payer. The other part of the process is much more devious, as it means choking off new activity, even when sound, to avoid any new build up of assets. Debts that mature and are paid help shrink the balance sheet; giving new loans goes against that process and is thus avoided as much as possible by banks right now.

New lending activity is therefore much more scrutinized from a risk perspective, sees its conditions made much less favorable than they used to be, and is especially frowned upon for long term commitments, as long term liquidity is scarce and expensive.

In my case, working in a bank that suffers from a huge gap between its predominantly long term assets, and its short term liabilities, was basically bankrupt earlier this autumn, had to be bailed out via nationalisation and has not yet announced its forthcoming strategy (ie I still don't know yet if my ativity will be a "core business" or not), funding has been especially restricted.

The wind sector requires long term funding in order to spread out the initial investment over a long enough period (so that the levelized cost per MWh is low enough) and it was a massive user of debt finance to get investments done. This means that it is an industry particularly vulnerable to the credit crunch. And indeed, expectations are that the fourth quarter will show a severe drop in new activity. Construction will still be at a record high, as projects which got their financing in the past year and a half get built, but new funding is drying up and next year is thus likely see a significant drop in actual building activity as those investors that relied on debt finance have more difficuly finding it and have to delay their plans.

In this context, I must admit that I'm especially pleased to be able to announce that we closed the financing of a new wind project, with a $60 million loan to build, over the next 12 months, a 30MW wind farm in the Caribean island of Aruba (part of the Kingdom of the Netherlands).

The Problem with Making Predictions - Oil or Climate

One of my most enduring memories of Washington D.C. occurred while attending a meeting on Geothermal Energy Development, back in the days before the Iron Curtain fell. In the evening after dinner, I took a colleague from Eastern Europe, on his first American visit, for a walk down the Mall. We walked, almost alone, on a still, bitterly cold, dark evening with fresh snow on the ground, and stars peppering the sky above us to see the sights, including the Lincoln Memorial. We stood staring, like backwoods tourists, through the windows of the Air and Space Museum.

We came back to the hotel for alcoholic refueling, thinking that the energy problems of the time would guarantee unending research funding into new forms of energy, and that our future was assured. That was about thirty years ago, and we were, of course, wrong, at least in terms of the funding and sustained interest in unconventional energy sources. Now we are walking back over some of the same ground. Again, fluctuations in oil prices have removed the immediate perception of the need for alternate supply, and have also weakened the credibility of those of us who try to suggest how to deal with the problem.

Prophecy, particularly when it deals with the near term future runs the risk of being corrected by the actual turnout of events. The ups and downs of energy demand, and available supply–-particularly when tied to the economic fortunes of nations, can make logical projection under one condition, but become apparently hopelessly in error when that condition doesn’t happen. Thus, at the moment, with the declining price, and apparent glut of oil, the public no longer feels that there is a crisis; the credibility of those forecasting a crisis is damaged, and can only be reconstructed over a longer period of time and changing circumstance.

Author's note: I have added a comment to the bottom of the post.

Impact of Credit Crisis on the Energy Industry - Where Are We Now?

I recently looked through news articles to see which energy sectors were being affected by the credit crisis. I was amazed at how widespread and how devastating the impact is.

There are really two closely related problems. One is reduced access to credit, making new borrowing difficult for nearly every business that requires debt. Prices for all commodities have been dropping as well. At least part of the reason for this price decline is the lack of availability of credit—many of the less credit-worth buyers drop out of the market. This leaves fewer buyers and almost the same number of sellers, so the price drops.


In this post, I examine how reduced access to credit and the concomitant decline in commodity prices is affecting energy companies.
