Why We Can't Afford Cheap Gas

With the cost of crude oil again nearing the $100-a-barrel mark (even after last week’s financial meltdown) and this summer’s record gas prices in the rearview mirror, automotive executives and industry analysts are already heralding the return of gas-guzzling trucks and SUVs. Car makers are rolling out new truck models, and even Republican presidential candidate John McCain, in a new Michigan TV spot, promises to "spur truck sales." Never mind that only months earlier, these same analysts, as well as auto executives and consumers alike, insisted that the future of the automotive industry lay in more fuel-efficient models like hybrid and electric cars. Now, however, it seems that many involved are slowly slipping back into the pre-$100-per-barrel mindset that was so popular when pump prices were under $4 a gallon and drivers of SUVs and trucks roared down the roads with clean consciences.

But if history is any indication, this period of relief and a possible shift back to gas-guzzling cars must be met with cold-eyed skepticism. Sure, cheaper gas means much needed short-term financial relief. Looking past the next year or two, however, cheaper oil and a resurgence of gas-guzzling vehicles would be seriously detrimental to the United States, as similar oil crises in the past have shown that the periods immediately after a spike in oil prices -- not the crises themselves -- have arguably inflicted far greater damage on the country. During these relief periods, critical efforts to develop alternative energies and fuel-efficient technologies -- begun under the culture of urgency that an energy crisis instills -- have been squashed, allowing Americans to revert to the same old habits, tendencies and behaviors that got them into trouble in the first place.

Take, for example, the October 1973 U.S. oil embargo. After a group of African and Middle Eastern countries briefly stopped supplying the United States with oil, prices in early 1974 climbed from $3 to $11 per barrel, setting off a nationwide energy panic and resulting in massive lines at gas stations. In response, President Richard Nixon proposed lowering speed limits on federal and state highways and temporarily banning the sale of gasoline on Sundays. Nixon also announced his "Project Independence," a set of energy-related recommendations aimed at achieving the quixotic goal of making the United States energy independent by 1980.

Though Nixon succeeded in lowering speed limits and imposing the Sunday ban for a brief period, Project Independence floundered. As oil prices began to drop after the '73 embargo, Nixon's vision of a United States "that will not be dependent on any other country for the energy we need to provide our jobs, to heat our homes and to keep our transportation moving" was reduced to a flimsy "blueprint" passed on to his successor, Gerald Ford, in late 1974. Time reported that the weakened blueprint would "not be an action program, but rather a listing of options for debate within government and eventual White House decision." Under Ford, Project Independence soon disappeared, and although Ford renewed his predecessor's goal for making the United States energy independent (this time, by 1985), Americans quickly reverted back to good old reliable oil.

In 1979, this same narrative of an oil crisis, a subsequent "commitment" to energy independence and then an immediate scrapping of alternative energies research played out once more. After the Iranian Revolution and the ousting of the Shah of Iran, a worldwide oil panic ensued in which the cost of a barrel of crude oil in April 1980 shot up to a record $39.50, or $103.76 in today's money when adjusted for inflation. Like the '73-'74 crisis, the lines at gas pumps grew, rationing measures were implemented, and hysteria quickly spread throughout the country.

In response, President Jimmy Carter took swift action. Three months after oil costs peaked, Carter signed into law the Energy Security Act, a sweeping piece of legislation he described as the "keystone of U.S. national energy policy." Then-House Majority Leader Jim Wright said at the time that the Energy Security Act was one of the most important pieces of legislation of the entire decade. In committing hundreds of billions of dollars toward developing alternative energies, the act's goal was to decrease U.S. dependence on foreign oil by creating the United States' first solar bank and investing in biomass, geothermal and ocean thermal energies.

The Energy Security Act's backbone, however, was the Synthetic Fuels Corporation, an organization created to spur the development of synthetic oil equivalents by funding private companies developing synthetic fuels. Carter's legislation set a goal for the SFC to establish enough synthetic fuel research and development projects to produce at least 500,000 barrels per day of oil equivalent by 1987. And to meet this goal, the Carter administration invested heavily in the SFC. The Energy Security Act authorized an initial $20 billion in funding over five years for the SFC, with the possibility of Congress spending another $68 billion after 1985 to encourage the further production of synthetic fuels.

As it turned out, SFC was doomed from the start. The corporation was plagued by management problems. Numerous front office officials took criticism for what outsiders saw as excessively high salaries. And once the Reagan administration came into power, bringing with it a zealous belief in unfettered free markets, SFC was perceived to be an unwelcome interference. "The Reagan administration might not object too loudly if SFC is shelved," Oil and Gas Journal reported in 1984 as the corporation found itself under fire. "It never has been fond of SFC, which runs counter to its free market philosophy."

But what truly signaled the death knell for SFC -- as well as other ongoing alternative energy research efforts -- was the return of cheap oil. Just as the wheels of SFC began to slowly turn, a worldwide surplus in crude oil developed, and the urgency that once fueled the drive for new energy sources dissipated. When, in December 1985, Congress terminated all funding for the much-loathed SFC, the New York Times reported that SFC "was a victim of falling world oil prices." And in what can be read as SFC's obituary the following April, the Times stated that "the decline in oil prices over the last few years led members of Congress to question the wisdom of pouring millions of dollars into what have been termed questionable projects."

David Cole, the chairman of the Center for Automotive Research in Ann Arbor, Mich., and an automotive industry researcher during the 1970s, explained in a recent interview that "research on batteries and alternative fuels instantly stopped after the Iranian crisis. Fuel economy was just the furthest thing from anyone's mind when the crisis ended."

Looking now to the present, what concerns analysts like Cole is a similar disaffection and abandonment of alternative energies research due to cheaper oil. "It would be particularly tragic now if we had a collapse, because we're so far along in the basic technologies," Cole said. What's different about the periods after the 1973 and 1979 oil crises and this year's, he explained, is that in the 1970s and 1980s the key inventions needed to really bring to the market technologies like biofuels, lithium batteries and other alternative energy sources hadn't been made. Today, citing ongoing projects like the lithium battery-powered Chevrolet Volt, Cole said that "the inventions are in place."

Thus it's even more critical that existing alternative energies research continues to receive support, even if that research is costly and slow moving. This perceived lack of progress in part doomed the SFC: A year before the corporation went belly-up, lawmakers criticized SFC for its "desultory progress" in meeting its goals and its "slow decision making." Yet such research will always be slow, and critics of such programs need to trust that long-term progress is being made even if it isn't immediately perceptible.

To prevent a similar energy relapse and end the United States' addiction to domestic and foreign oil, many analysts, executives, industry experts and journalists support increasing petroleum taxes and implementing an oil price floor. This would set a minimum price for the cost of a barrel of oil so that even if the market cost of oil dropped past the floor, gas prices would remain at a set price. As Philip Gordon, a senior fellow for U.S. foreign policy at the Brookings Institution, argues, "Americans will not make long-term decisions to buy fuel-efficient automobiles, create distribution networks for alternative fuels, or invest in technologies like hydrogen fuel cells, flex-fuel vehicles or wind power unless they know that a future sharp fall in oil prices will not undercut them."

Cole said that if an oil price floor is to be considered, it must be done somewhat soon, as Americans are more likely to agree with implementing a floor when oil prices are still high. A minimum gas price, he added, would also bring new fuel-efficient cars -- among them more efficient hybrid models and fully battery-powered cars -- into large-scale production and onto dealership lots far sooner.

However, the likelihood that Congress would increase gas taxes and establish an oil floor -- a move sure to draw the ire of many, many Americans -- is nonexistent. "Congress has been absolutely afraid of raising fuel taxes, and has a history of avoiding taxes on fuel," Cole said.

In all fairness, it's unclear whether the recent decreases in oil prices are part of a larger downward trend or are instead anomalous. Some believe the "great oil bubble has burst;" others warn of more high prices on the horizon. Thus it's too early to tell if the cheap oil mentality starting to reappear today will last as long as it did after previous crises.

But even if the current relief is short-lived, as some analysts and experts say, there's still very much the possibility that even this short period could hinder or shortchange critical research and development on alternative energies and fuel-efficient cars. And this cannot happen. Surely the need for alternative energies and reducing the United States' -- and the world's -- dependence on oil has never been greater, as evidenced by the impassioned pleas of climate change scientists who argue that global warming will kill off vast numbers of animals and plants in our lifetime and, ultimately, humans as well. The American Petroleum Institute strongly emphasized, "We cannot solve our major energy problem, the nation's heavy reliance on foreign oil, unless we continue to develop all economical forms of U.S. energy." That statement could easily apply to the present moment; in fact, it was made more than 24 years ago, right around the time the SFC was nearing its demise. Still, it's never too late to heed such wisdom.

McCain Is Absent on America's Energy Crisis, Misses Eight Key Votes

John McCain recently tried to underscore his seriousness about pushing through a new energy policy, with a strong focus on more drilling for oil, by telling a motorcycle convention that Congress needed to come back from vacation immediately and do something about America's energy crisis. "Tell them to come back and get to work!" McCain bellowed.

Sorry, but I can't let that one go by. McCain knows why.

It was only five days earlier, on July 30, that the Senate was voting for the eighth time in the past year on a broad, vitally important bill -- S. 3335 -- that would have extended the investment tax credits for installing solar energy and the production tax credits for building wind turbines and other energy-efficiency systems.

Both the wind and solar industries depend on these credits -- which expire in December -- to scale their businesses and become competitive with coal, oil and natural gas. Unlike offshore drilling, these credits could have an immediate impact on America's energy profile.

Senator McCain did not show up for the crucial vote on July 30, and the renewable energy bill was defeated for the eighth time. In fact, John McCain has a perfect record on this renewable energy legislation. He has missed all eight votes over the last year -- which effectively counts as a no vote each time. Once, he was even in the Senate and wouldn't leave his office to vote.

"McCain did not show up on any votes," said Scott Sklar, president of The Stella Group, which tracks clean-technology legislation. Despite that, McCain's campaign commercial running during the Olympics shows a bunch of spinning wind turbines -- the very wind turbines that he would not cast a vote to subsidize, even though he supports big subsidies for nuclear power.

Barack Obama did not vote on July 30 either -- which is equally inexcusable in my book -- but he did vote on three previous occasions in favor of the solar and wind credits.

The fact that Congress has failed eight times to renew them is largely because of a hard core of Republican senators who either don't want to give Democrats such a victory in an election year or simply don't believe in renewable energy.

What impact does this have? In the solar industry today there is a rush to finish any project that would be up and running by Dec. 31 -- when the credits expire -- and most everything beyond that is now on hold. Consider the Solana concentrated solar power plant, 70 miles southwest of Phoenix in McCain's home state. It is the biggest proposed concentrating solar energy project ever. The farsighted local utility is ready to buy its power.

But because of the Senate's refusal to extend the solar tax credits, "we cannot get our bank financing," said Fred Morse, a senior adviser for the American operations of Abengoa Solar, which is building the project. "Without the credits, the numbers don't work." Some 2,000 construction jobs are on hold.

Roger Efird is president of Suntech America -- a major Chinese-owned solar panel maker that actually wants to build a new factory in America. They've been scouting the country for sites, and several governors have been courting them. But Efird told me that when the solar credits failed to pass the Senate, his boss told him: "Don't set up any more meetings with governors. It makes absolutely no sense to do this if we don't have stability in the incentive programs."

One of the biggest canards peddled by Big Oil is that, "Sure, we'll need wind and solar energy, but it's just not cost effective yet." They've been saying that for 30 years. What these tax credits are designed to do is to stimulate investments by many players in solar and wind so these technologies can quickly move down the learning curve and become competitive with coal and oil -- which is why some people are trying to block them.

As Richard K. Lester, an energy-innovation expert at the Massachusetts Institute of Technology, notes, "The best chance we have -- perhaps the only chance" of addressing the combined challenges of energy supply and demand, climate change and energy security "is to accelerate the introduction of new technologies for energy supply and use and deploy them on a very large scale."

This, he argues, will take more than a Manhattan Project. It will require a fundamental reshaping by government of the prices and regulations and research-and-development budgets that shape the energy market. Without taxing fossil fuels so they become more expensive and giving subsidies to renewable fuels so they become more competitive -- and changing regulations so more people and companies have an interest in energy efficiency -- we will not get innovation in clean power at the scale we need.

That is what this election should be focusing on. Everything else is just bogus rhetoric designed by cynical candidates who think Americans are so stupid -- so bloody stupid -- that if you just show them wind turbines in your Olympics ad they'll actually think you showed up and voted for such renewable power -- when you didn't.

We Can Stop Global Warming

Scientists now tell us that the crisis of global warming is even worse than their earlier projections. Daily front-page headlines of environmental disasters give an inkling of what we can expect in the future, multiplied many times over: droughts, floods, severe weather disturbances, loss of drinking water and farmland and conflicts over declining natural resources.

Yet the situation is by no means hopeless. Major advances and technological breakthroughs are being made in the United States and throughout the world that are giving us the tools to cut carbon emissions dramatically, break our dependency on fossil fuels and move to energy efficiency and sustainable energy. In fact, the truth rarely uttered in Washington is that with strong governmental leadership the crisis of global warming is not only solvable; it can be done while improving the standard of living of the people of this country and others around the world. And it can be done with the knowledge and technology that we have today; future advances will only make the task easier.

What should we be doing now?

First, we need strong legislation that dramatically cuts back on carbon emissions. The Global Warming Pollution Reduction Act (S. 309), a bill that I introduced with Senator Barbara Boxer and that now has eighteen co-sponsors, would reduce greenhouse gas emissions by 80 percent by the year 2050.

Second, if the federal government begins the process of transforming our energy system by investing heavily in energy efficiency and sustainable energy, we can accomplish the 80 percent carbon reduction level and, at the same time, create millions of high-paying jobs.

Energy efficiency is the easiest, quickest and least expensive path toward the lowering of carbon emissions. My hometown of Burlington, Vermont, despite strong economic growth, consumes no more electricity today than it did sixteen years ago because of a successful effort to make our homes, offices, schools and other buildings more energy-efficient. In California, which has a growing economy, electric consumption per person has remained steady over the past twenty years because of that state's commitment to energy efficiency.

Numerous studies tell us that retrofitting older buildings and establishing strong efficiency standards for new construction can cut fuel and energy consumption by at least 40 percent. Those savings would increase with the adoption of new technologies such as LED light bulbs, which consume as little as 10 percent of the electricity that incandescent bulbs do and last twenty years.

Transportation must also be addressed in a serious manner. It is insane that we are driving cars today that get the same twenty-five miles per gallon that US cars did twenty years ago. If Europe and Japan can engineer their vehicles to average more than forty-four miles per gallon, we can do at least as well. Simply raising fuel-efficiency standards to forty miles per gallon would save roughly the same amount of oil as we import from Saudi Arabia and would dramatically lower carbon emissions. We should also rebuild and expand our decaying rail and subway systems and provide energy-efficient buses in rural America so that travelers have an alternative to the automobile.

Sustainable energies such as wind, solar and geothermal have tremendous potential and often cost no more than fossil fuels (and, in some cases, even less). Increased production and research should cause sustainable energy prices to decline steeply in the future.

Wind power is the fastest growing source of new energy in the world and in the United States, but we have barely begun to tap its potential. Denmark, for example, generates 20 percent of its electricity from wind. We should be supporting wind energy not only through the creation of large wind farms in the appropriate areas but through the use of small, inexpensive wind turbines available today that can be used in homes and farms throughout rural America. These small turbines can produce, depending on location, more than half the electricity that an average home consumes while saving consumers money on their electric bills.

Solar energy is another rapidly expanding technology. In Germany, a quarter of a million homes are now producing electricity through rooftop photovoltaic units, and the cost of that technology is expected to decline steeply. California is providing strong incentives so that 1 million homes will have solar units in the next ten years. The potential of solar energy, however, goes far beyond rooftop photovoltaic units. Right now, in Nevada, a solar plant is generating fifty-six megawatts of electricity. According to the National Renewable Energy Laboratory of the US Energy Department, "Solar energy represents a huge domestic energy resource for the United States, particularly in the Southwest where the deserts have some of the best solar resource levels in the world. For example, an area approximately 12 percent the size of Nevada has the potential to supply all of the electric needs of the United States."

As a strong indication of what the future holds, Pacific Gas and Electric, the largest electric utility in the country, has recently signed a contract to build a 535-megawatt solar thermal plant in the Mojave Desert. This plant, which should be operating in about four years, will have an output equivalent to a small nuclear power plant and will produce electricity for about 400,000 homes. Most important, the price of the electricity generated by this plant, about 10 cents per kilowatt hour, is competitive with other fuels today and will be much cheaper than other fuels by the end of the twenty-five-year contract. Experts in the industry say that dozens of these plants can be built within the next twenty years.

Geothermal energy, the heat from deep inside the earth, is another overlooked resource with real potential. It is free, renewable and can be used for electricity generation and direct heating. A recent report for the US Energy Department by the Massachusetts Institute of Technology suggests that geothermal could supply 100,000 megawatts of new carbon-free electricity at less than 10 cents per kilowatt hour, the going rate today. It is estimated that electricity from geothermal sources could provide 10 percent of the US baseload energy needs in 2050.

As the nation at last confronts global warming, it is no time for denial, greed, cynicism or pessimism. It is a time for vision and international leadership. It is a time for transforming our energy system from the polluting and carbon-emitting technologies of the nineteenth century into the unlimited and extraordinary energy possibilities of the twenty-first. When we do that we will not only solve the global warming crisis; we will open up unimaginable opportunities for improving life all over the planet.

The Dirty Energy Solution

From his desk in an office in Chicago, Jeff Smith has a bird's-eye view of the American landscape. Combing through a huge database of information compiled by the EPA, he can, almost literally, peer down every smokestack in the nation and figure out what's going on inside.

And what he sees is heat. Waste heat -- one of the country's largest potential sources of power, pouring up out of those smokestacks. If it could be recycled into electricity, that heat would generate immense amounts of power without our having to burn any new fossil fuels. By immense, I mean, speaking technically, humongous. Even after he's winnowed the nation's half a million smokestacks down to the most likely customers, that leaves twenty-five thousand stacks. "An astronomical number," Smith says.

His boss at Recycled Energy Development, Sean Casten, leafs through the reams of data Smith has compiled. The biggest sources of waste heat are some gas turbines used to generate power, but there are endless other examples. "Let's look at Florida," he says. "Here's a Maxwell House coffee roaster in Duval County. They're roasting beans, so all that heat has to go somewhere. About twelve megawatts' worth of potential electricity is going up the stack."

Casten could take the equipment he sells, a "waste-heat recovery boiler," and stick it on top of the stack. "Basically, there's a network of tubes with water in them. The heat would hit one side of it, produce steam, and we'd use that to turn a turbine and generate electricity. It's like any other boiler, just without a flame, because the heat is already there."
