"In a sustainable community, resource consumption is balanced by resources assimilated by the ecosystem. The sustainability of a community is largely determined by the web of resources providing its food, fiber, water, and energy needs and by the ability of natural systems to process its wastes. A community is unsustainable if it consumes resources faster than they can be renewed, produces more wastes than natural systems can process or relies upon distant sources for its basic needs."

The Peak Oil Crisis: Cold Fusion Moves East

Many of us believe that life on this planet is in a lot of trouble. The climate is becoming unstable; there are too many people; oceans are dying, sea levels are rising; and water, food, clean air, and minerals are coming into short supply. For many, the economy refuses to grow fast enough to maintain living standards.

Although appreciated by only a handful, the evidence continues to build that, unless we have reached some kind of a tipping point, there may be a way out of our mounting problems. A few minutes’ reflection should be enough to convince most that a source of unlimited clean, cheap energy just could reverse global warming, provide unlimited water, food, and a better life for all.

While there may be sources of clean cheap energy that as yet we have no idea exist in this universe, for the present, cold fusion or the preferred term Low Energy Nuclear Reactions (LENR) looks like the only solution currently extant with the potential to save us. It may not be a stretch to say that either we develop and put into widespread use this technology or it is “game over” for life as we know it.

For the last 25 years, the U.S. government, at the urging of its scientific advisors who unfortunately had, and in some cases still have, axes to grind on the LENR issue, has been denying that the “cold fusion;” or LENR phenomenon, actually exists. According to the government, the anomalous heat that so many have been reporting on since 1989 is only experimental errors or scientific fraud or even wishful thinking. When the U.S. government says there is no such thing as “cold fusion” then naturally most other governments and the mainstream media with minor exceptions say the same.

This position may be changing however. While a few scientists at NASA have been saying that the LENR phenomenon is real for some time, the Department of Energy which reigns supreme in these matters remains pretty firm in its denial despite occasional reviews. Recently, however, we may have seen the beginnings of change when a component of DOE which funds exotic energy R&D efforts said it would entertain proposals to fund LENR experiments. Now this may simply be a case of the right hand not knowing what the left hand is doing, but it would be nice to believe that at least somewhere in DOE, a few are coming to their senses,

So where are we on this revolutionary and likely disruptive technology? There are dozens of independent laboratories around the world experimenting with low energy nuclear reactions at the lab bench scale, but only three or four saying, and in some cases demonstrating, that they have devices producing enough energy that commercially useful products should be available soon.

Readers of this column know by now that there is a small but devoted blogosphere out there in cyberspace that not only fervently believes that cold fusion is real and someday will save humanity, but follows and comments on developments daily.

For several years, interest has focused on the Italian inventor Andrea Rossi and his E-Cat nuclear device, which many still consider a scam despite numerous validations. Nearly a year ago, Rossi told his cyber space followers that he had partnered with a well-healed American firm that was helping him develop a commercial product. Until last week Rossi’s American partner was a well-kept secret with speculation focusing on industrial giants such as GE or United Technologies who have much to gain if LENR ever becomes a commercial product replacing combustion of fossil fuels as the principal source of heat in the world.

Last week a hint leaked out when one of Rossi’s associates noted in his biography that he was consulting for an obscure hedge fund called Cherokee Investment Partners LLC, located in Raleigh, North Carolina. The blogosphere jumped on this clue and within days enough information about Cherokee and its new subsidiary, Industrial Heat LLC, was brought to light to conclude that this organization is indeed Rossi’s new American partner in the development of LENR. Cherokee, which has a capitalization of circa $2 billion and has invested $11.5 in the E-Cat project, has a record of investing in cleaning up polluted properties and funding renewable energy projects.

Richard Heinberg's Museletter - The Climate-PR Puzzle

How do we effectively communicate an important but difficult message, even as it appears to fall on deaf ears? The first essay in this month's Museletter addresses this thorny issue, one which I face every day in my work here at PCI, and which will be familiar to many of you. The second essay is a reminder that in some places the message is getting through and that change does happen. Richard hopes that you will find some hope in his report from a recent visit to Seoul, Korea.

The Climate-PR Puzzle

If we hope to avert climate apocalypse in the decades ahead, we must make fundamental changes to industrial society. Before those changes can be approved and implemented, citizens and policy makers must first come to understand they are essential to our survival. Public relations—the management of the spread of information between an individual or organization and the public—will be an unavoidably necessary tool in the process.

But a PR message capable of persuading policy makers and citizens to end society’s environmental rampage remains elusive. In this essay I hope to explore why an effective PR message is so hard to formulate, and how the whole project might be reconsidered.

Let’s start with what needs to be conveyed. After years of research and thought, I would summarize our dilemma with three general conclusions:

1. Energy is the biggest single issue facing us as a species.*

Global warming—by far the worst environmental challenge humans have ever confronted—results from our current fossil-fuel energy regime, and averting catastrophic climate change will require us to end our reliance on coal, oil, and natural gas. Ocean acidification is also a consequence of burning fossil fuels, and most other environmental crises (like nitrogen runoff pollution and most air pollution) can be traced to the same source.

Therefore ending our addiction to fossil fuels is essential if we want future generations of humans (and countless other species) to inherit a habitable a planet. But these energy sources are “unsustainable” also in a more basic, economic sense of the term: oil, gas, and coal are depleting, non-renewable resources. Already, depletion of the easy-and-cheap sources of petroleum that drove economic growth in the 20th century has led to persistently high oil prices, which are a drag on the economy. We have picked the low-hanging fruit of the world’s petroleum resources, and as time goes on all sources of fossil energy will become more financially costly and environmentally risky to extract. This is a big problem because the economy is 100 percent dependent on energy. With lots of cheap energy, problems of all kinds are easy to solve (running out of fresh water? Just build a desalination plant!); when energy becomes expensive and hard to get, problems multiply and converge.

One way or another, whether our concern is the environment or economic growth, it’s mostly about energy.

*Arguably, overpopulation is as big an issue as our energy-climate conundrum. I’ve chosen not to focus on it here merely to streamline the narrative. There are many feedbacks between population, energy, and climate, and these deserve discussion elsewhere.

2. We are headed toward a (nearly) all-renewable-energy economy one way or the other, and planning is essential if we want to get there in one piece.

If society is to avoid civilization-threatening levels of climate change, the use of fossil fuels will have to be reduced proactively by 80-90 percent by 2050.

At the same time, despite the claims of abundance of unconventional fuels (shale gas, tight oil, tar sands) by the fossil fuel industry, evidence overwhelmingly shows that drillers are investing increasing effort to achieve diminishing returns.

Either way, fossil fuels are on their way out.

Most nations have concluded that nuclear is too costly and risky, and supplies of uranium are limited.

That leaves renewable energy sources—solar, wind, hydro, geothermal, tidal, and wave power—to power the economy of the future.

3. In the process of transition, the ways that society uses energy must change at least as much as the ways society produces energy.

Every energy source possesses a unique set of characteristics: some sources are more portable than others, or more concentrated, intermittent, scalable, diffuse, renewable, environmentally risky, or financially costly. We have built our current economy to take advantage of the special properties of fossil fuels. The renewable energy sources that are available to replace oil, gas, and coal have very different characteristics and will therefore tend to support a different kind of economy—one that is less mobile, more rooted in place; less globalized, more localized; less when-we-want-it, more when-it’s-available; less engineered, more organic.

At the same time, the sheer quantity of energy that will be available during the transition from fossil to renewable sources is in doubt. While ever-more-rapid rates of extraction of fossil fuels powered a growing economy during the 20th century, society will struggle to maintain current levels of total energy production in the 21st, let alone grow it to meet projected demand. Indeed, there are credible scenarios in which available energy could decline significantly. And we will have to invest a lot of the fossil energy we do have in building post-fossil energy infrastructure. Energy efficiency can help along the way, but only marginally.

The global economy will almost certainly stagnate or contract accordingly.

There it is. It is a complicated message. I’ve just conveyed it in 661 words punctuated by three short summary sentences (here’s a summation of the summation: it’s all about energy; renewables are the future; growth is over.) However, only readers with a lot of prior knowledge will be able to truly understand some of these words and phrases. And many people who are capable of making sense of what I’ve written would disagree with, or dismiss, much of it. The message faces a tough audience, and it flies against deep-seated interests.

Many economists and politicians don’t buy the assertion that energy is at the core of our species-wide survival challenge. They think the game of human success-or-failure revolves around money, military power, or technological advancement. If we toggle prices, taxes, and interest rates; maintain proper trade rules; invest in technology R&D; and discourage military challenges to the current international order, then growth can continue indefinitely and everything will be fine. Climate change and resource depletion are peripheral problems that can be dealt with through pricing mechanisms or regulations.

Fossil fuel companies may understand the importance of energy, but they have a powerful incentive to avoid acceptance of the message that “renewables are the future.” If humanity is headed toward an all-renewable energy economy, then their business has no future. The industry’s strategy for diverting the general public’s buy-in to conclusion 2 is to claim that there is plenty of oil, gas, and coal available to fuel society for decades to come.

Some policy wonks buy “it’s all about energy,” but are jittery about “renewables are the future” and won’t go anywhere near “growth is over.” A few of these folks like to think of themselves as environmentalists (sometimes calling themselves “bright green”)—including the Breakthrough Institute and writers like Stewart Brand and Mark Lynas. A majority of government officials are effectively in the same camp, viewing nuclear power, natural gas, carbon capture and storage (“clean coal”), and further technological innovation as pathways to the solution of the climate crisis without any need for curtailment of economic growth.

Other environment-friendly folks buy “it’s all about energy” and “renewables are the future,” but still remain allergic to the notion that “growth is over.” They say we can transition to 100 percent renewable power with no sacrifice in terms of economic growth, comfort, or convenience. Stanford professor Mark Jacobson and Amory Lovins of Rocky Mountain Institute are leaders of this chorus. Theirs is a reassuring message, but if it doesn’t happen to be factually true (and there are many energy experts who argue persuasively that it isn’t), then it’s of limited helpfulness because it fails to recommend the kinds or degrees of change in energy usage that are essential to a successful transition.

The general public tends to listen to one or another of these groups, all of which agree that the climate and energy challenge of the 21st century can be met without sacrificing economic growth. This widespread aversion to the “growth is over” conclusion is entirely understandable: during the last century, the economies of industrial nations were engineered to require continual growth in order to produce jobs, returns on investments, and increasing tax revenues to fund government services. Conclusion 3, which questions whether growth can continue, is therefore deeply subversive. Nearly everyone has an incentive to ignore or avoid it. It’s not only objectionable to economic conservatives, it is abhorent to many progressives who believe economies must continue to grow so that the “under-developed” world can improve standards of living.

But ignoring uncomfortable facts seldom makes them go away. Often it just makes matters worse. Back in the 1970s, when environmental limits were first becoming apparent, catastrophe could have been averted with only a relatively small course correction—a gradual tapering of growth and a slow decline in fossil fuel reliance. Now, only a “cold turkey” approach will suffice. If a critical majority of people couldn’t be persuaded then of the need for a gentle course correction, can they now be talked into undertaking deliberate change on a scale and at a speed that might be nearly as traumatic as the climate collision we’re trying to avoid?

To be sure, there are those who do accept the message that “growth is over”: most are hard-core environmentalists or energy experts. But this is a tiny and poorly organized demographic. If public relations consists of the management of information flowing from an organization to the public, then it surely helps to start with an organization wealthy enough to be able to afford to mount a serious public relations campaign.

This is all quite discouraging, to the point that a fourth conclusion seems justified: More
