Al Gore's Speech  

Al Gore's speech yesterday was a masterpiece from my point of view - outlining most of the solutions to our energy issues (fixing and expanding the grids, energy efficiency, solar, wind, geothermal, electric cars etc etc etc) and many of the political factors involved (especially Iraq and the defenders of the status quo who took us there, and the culture war that has paralysed America).

Best of all (unlike "An Inconvenient Truth") he set an ambitious target for implementing the solutions - a switch to 100% renewable energy by 2020 for the United States (none of this 20% by 2020 nonsense that the weak-kneed keep offering up as a way forward) - something we should be attempting globally.

The speech is online now.

It was interesting that one of the people he thanked for attending was the Libertarian candidate for President - hopefully the libertarians are all starting to get on board with the idea of market based solutions to global warming and peak oil.

From The New York Times' review - Gore Calls for Carbon-Free Electric Power.

Former Vice President Al Gore said on Thursday that Americans must abandon electricity generated by fossil fuels within a decade and rely on the sun, the winds and other environmentally friendly sources of power, or risk losing their national security as well as their creature comforts. “The survival of the United States of America as we know it is at risk,” Mr. Gore said in a speech to an energy conference here. “The future of human civilization is at stake.”

Mr. Gore called for the kind of concerted national effort that enabled Americans to walk on the moon 39 years ago this month, just eight years after President John F. Kennedy famously embraced that goal. He said the goal of producing all of the nation’s electricity from “renewable energy and truly clean, carbon-free sources” within 10 years is not some farfetched vision, although he said it would require fundamental changes in political thinking and personal expectations.

“This goal is achievable, affordable and transformative,” Mr. Gore said in his remarks at the conference. “It represents a challenge to all Americans, in every walk of life — to our political leaders, entrepreneurs, innovators, engineers, and to every citizen.”

Although Mr. Gore has made global warming and energy conservation his signature issues, winning a Nobel Prize for his efforts, his speech on Thursday argued that the reasons for renouncing fossil fuels go far beyond concern for the climate.

In it, he cited military-intelligence studies warning of “dangerous national security implications” tied to climate change, including the possibility of “hundreds of millions of climate refugees” causing instability around the world, and said the United States is dangerously vulnerable because of its reliance on foreign oil. ...

Mr. Gore said the most important policy change in the transformation would be taxes on carbon dioxide production, with an accompanying reduction in payroll taxes. “We should tax what we burn, not what we earn,” he said.

The former vice president said in his speech that he could not recall a worse confluence of problems facing the country: higher gasoline prices, jobs being “outsourced,” the home mortgage industry in turmoil. “Meanwhile, the war in Iraq continues, and now the war in Afghanistan appears to be getting worse,” he said.

By calling for new political leadership and speaking disdainfully of “defenders of the status quo,” Mr. Gore was hurling a dart at the man who defeated him for the presidency in 2000, George W. Bush. Critics of Mr. Bush say that his policies are too often colored by his background in the oil business.

A crucial shortcoming in the country’s political leadership is a failure to view interlocking problems as basically one problem that is “deeply ironic in its simplicity,” Mr. Gore said, namely “our dangerous over-reliance on carbon-based fuels.”

“We’re borrowing money from China to buy oil from the Persian Gulf to burn it in ways that destroy the planet,” Mr. Gore said. “Every bit of that’s got to change.”

And it can change, he said, citing some scientists’ estimates that enough solar energy falls on the surface of the earth in 40 minutes to meet the world’s energy needs for a year, and that the winds that blow across the Midwest every day could meet the country’s daily electricity needs.

More at the FT - Gore seeks 100% green energy.

Energy Bulletin has a transcript of the speech.

Jerome Guillet has a run down of how the solution could be implemented at TOD, focussing primarily on wind power, which is his area of expertise (I think he greatly understates the potential for solar in the time frame available) - Gore sets goal of 100% carbon-free electricity by 2020.

Al Gore has made a major speech in Washington this morning, setting out an ambitious goal for the USA to produce all of its electricity from carbon-free sources by 2020. I thought I'd comment on the technical feasibility of the plan, and the underlying economics of such an endeavour.

The short answer is: while 100% is probably unrealistic, it's not unreasonable to expect to be able to get pretty close to that number (say, in the 50-90% range) in that timeframe, and it is very likely that it makes a LOT of sense economically. ...

For the simplicity of this discussion, I will focus on wind, given that it presents a bigger challenge on the intermittency front (which the inclusion of solar can only help improve), and that it would drive the ecohnomics of such a plan given its larger scale deployment.

The main questions, of course are as follows:
1) is it technically feasible to build the requisite capacity within 12 years?
2) what will it cost, and what will it mean for power prices?
3) how can the intermittency issue be dealt with?

Technical feasibility

To get 2,000 TWh of electricity from wind, roughly 800GW of wind power capacity would be needed, considering that windfarms would get an annual production equivalent to 2,500 full hours (a pretty conservative estimate, given that the existing wind farms are closer to 3,000 hours today). 800GW is roughly equal to 30 times the currently installed capacity (which should reach about 23GW at the end of this year) and 100 times the capacity installed in 2008 (expected to be close to 8,000MW, after 5,000MW were installed in 2007).

To build 800 GW in 12 years would require a significant increase in annual installations - but actually not an unrealistic one. ...

Altogether, the plan would require boosting investment in wind production capacity to about $100-150 billion per year, a significant number but hardly one that would require a complete retooling of the US economy. With a stable regulatory framework (presumably provided if this were made a national priority) and guaranteed demand (which could come via very simple mechanisms, like a feed-in tariffs, ie mandatory purchases by local utilities at regulated rates), there is absolutely no reason to doubt that this could be done.

I'll address the requirement to boost the grid separately below.

Wind power economics are quite simple: most of the levelised production cost per MWh comes from the initial investment. It is thus naturally sensitive to investment costs, and even more so to financing costs, both of which are determined at the time of construction. Once a windfarm is built, its production costs are essentially set for the rest of its operating life, ie 20-25 years. The fixed nature of its cost base makes it a difficult bet in a deregulated universe, where prices can swing wildy (including to low prices that can be insufficient for the windfarm to service its debt burden, thus the requirement for feed-in tariffs or similar mechanisms to guarantee a floor to wind electricity). But such fixed prices make wind a great proposition at times of increasing oil&gas costs: wind power prices will NOT increase even if oil & gas or coal prices continue to go up, as is quite possible.

Thus wind power is a wonderful hedge against future energy prices. And given that today it already costs less than power from a ges-fired plant (the plants that typically drive the price of electricity on wholesale markets), it is both competitive and likely to remain so in the coming years.

And given the cost structure of wind, a very simple way for government to support wind at very little cost would be to provide funding for the sector at low interest rates. One big advantage of government is its ability to borrow at lower rates - indeed, government sets the lowest rates that are by the rest of the economy. By passing on its low cost of funding to wind developments, the final cost of wind power could be lowered significantly, and passed on to consumers (banks would still be required to hold onto operational and other risks linked to wind production, they would just get cheaper funding for that specific purpose, which the'd have to fully pass on to projects. Germany has successfully used such a mechanism for years).

Studies in Germany and Denmark show that wind power lowers wholesale prices by 30 to 70% when wind blows, and that the overall savings for consumers far outstrip the cost of guaranteeing to wind producers a regulated tariff. Ironically, the more wind power there is in the system, and the lower the wholesale marker price will be most of the time, which means that the regulated tariff remains a necessity to ensure that wind producers are able to pay off the debt linked to their initial investment. But that regulated tariff is known, is realtively low, and,again, will not need to increase over time, thus ensuring to consumers similarly stable retail prices. ...

Overall, network operators with actual wind experience seem confident that a combination of additional investment, smart grid management, and maintaining available (but not using much) a large gas-fired capacity can make it possible to cope with large amounts of wind power in the system.

While a goal of 100% of carbon-free electricity is probably unrealistic, it therefore seems possible to get pretty close to that, especially if nuclear and hydro are included in the mix. A plan that announced a specific goal of 40-50% of wind-generated electricity by 2020 and 10-20% of solar, with the appropriate feed-in mechanisms, demand guarantees for manufacturers and investment in the grid would therefore be realistic, make economic sense, and fulfill two major strategic goals: reduce carbon emissions, and lower fossil fuel demand.
