Daylight Saving: Energy Policy or Placebo?

Richard M. Nixon
Cover of Richard M. Nixon
POWER Magazine

In December 1973, President Richard Nixon explained to the American people his administration’s critical initiative to confront the “energy crisis” du jour (precipitated by the 1973–74 Arab oil embargo): “Many [energy savings measures] require inconvenience and sacrifice. But daylight saving time... will mean only a minimum of inconvenience and will involve equal participation by all. Unlike many of our other initiatives to deal with the energy crisis and to accomplish the goal of self-sufficiency in energy... these savings will not require research, new technology, diplomacy, or exploration.”

Jimmy Carter

In the almost four decades since President Nixon resurrected daylight saving as a critical component of national energy policy, our populace has clung to the hope that such a “no cost/no sacrifice” silver bullet would rescue us from each succeeding energy crisis. The nation accordingly ignored President Jimmy Carter’s admonition that confronting our energy exigencies required great sacrifices approaching the “moral equivalent of war.”…

Historical Background

Benjamin Franklin is credited as the first to identify the potential fuel savings associated with adjusting the clock. …

In 1918, U.S. federal law standardized the start and end dates for daylight saving. During World War II, Congress mandated daylight saving throughout the 50 states. Following the end of the war, other than 1973 and 1974, the daylight saving time period was 26 or 27 weeks. Beginning in 1988, federal legislation extended the period to 29 or 30 weeks. A 1975 federal study concluded that these measures reduced overall electric consumption by 1%. In a 1976 report to Congress, “Review and Technical Evaluation of the DOT Daylight Saving Time Study,” the National Bureau of Standards found no significant energy savings.

Energy Policy Act of 2005: Same Old, Same Old

2003, reaching $60 a barrel by summer 2005. Congress passed the Energy Policy Act of 2005 (EPACT) to respond this “second energy crisis.” Prices ultimately peaked at just under $150 in mid-2008, before declining due to the financial crisis and associated global recession.

… Congress, however, essentially “dropped back 30 years” and … reverted to President Nixon’s political acumen to prioritize a policy promising “no cost/no inconvenience.”

… Our clocks now “spring ahead” on the second Sunday in March and “fall back” on the first Sunday in November. This 34-week period observed by most of the United States likely represents the world’s longest daylight saving period, exceeding the period in European nations by three or four weeks.

Energy Policy or Legislative Placebo?

At one level, EPACT’s expansion of daylight saving time could be viewed as a success: Almost no

government funds were spent. The Department of Energy (DOE) also claims the extension reduced energy consumption … less than 0.5% and, moreover, only during the additional weeks of daylight saving in March and October. Critics challenged the validity of even this near-negligible energy reduction and argued further that on an annual basis this transitory savings is probably statistically insignificant. Furthermore, the fundamental debate over whether daylight saving time saves total energy consumption at all times and in all localities remains; critics contend that having more daylight hours increases air conditioning electric load and “leisure” gas consumption.

… Our nearly half-century experience responding to energy crises demonstrates that national energy policy must be developed with the understanding that there are no quick fixes and that success demands public and private investment, measured risk-taking (not all of which proves successful), and technological advances.

Energy policy must be crafted based on current facts and circumstances. President Nixon’s reliance on daylight saving made sense—increasing daylight hours in the 1970s represented the easily attainable “low-hanging fruit” of energy efficiency. However, EPACT expanded daylight saving only because “it worked before” and to avoid the political awkwardness of pursuing meaningful energy measures. … . Daylight saving should be assessed on its comparative social and economic costs and benefits. As a means to reduce energy consumption, daylight saving, particularly any further expansion of its duration, must be dismissed as a distracting placebo.

WTE: Next-Generation Sustainable Energy

Power Magazine July 2010

excerpts:
The typical question I hear after lectures and presentations on WTE technologies is, "Why aren't we doing more of this?" The simple answer I give is that preconceived notions, based on incinerator emissions before the MACT regulations, have held back development. But that is changing.

English: Annual electricity net generation fro...Image via WikipediaCurrently, WTE constitutes about 25% of the renewable energy produced in the U.S. That percentage has the potential to grow because only 7% of waste is converted to energy via WTE, 64% if landfilled, and the remaining 29% is recycled.

Encouragingly, WTE was identified among eight emerging green technologies in a report from the Davos World Economic Forum in 2009 entitled "Green Investing: Towards a Clean Energy Infrastructure."

Trash To Cash: Mining Landfills For Energy And Profit

Fast Company

BY Ben Schiller Wed Sep 7, 2011

A Belgian company is working on removing the raw materials from dumps, making both energy and building materials out of them, and then redeveloping the land.

… Dating from the 1960s, the Remo Milieubeheer landfill at Houthalen-Hechteren is a typical dump full of industrial waste and household garbage--16.5 million tons of it in all.
Hardly the sort of the place to get anyone excited.

Except, that is, Patrick Laevers, director of Group Machiels, the Belgian waste management company that owns the site. Laevers has a 20-year plan to excavate the entire expanse, recycling about 45% of its contents, and converting the rest into electricity.

Eventually, … he hopes to turn the site back to nature. What's more, Laevers thinks Houthalen-Hechteren could be the first of many such projects around the world. “We really believe this concept is the future, and that we can all benefit from it,” he says….

Machiels has formed a joint venture with Advanced Plasma Power, a U.K. energy-to-waste company that converts the non-recyclable residue into a mixture of clean-burning natural gas--which generates electricity for 100,000 homes--and a building material called Plasmarok.

Machiels hopes the scheme, which has cost hundreds of millions of dollars, will be fully operational in 2014….

Rolf Stein, CEO of Advanced Plasma Power, says “the mind boggles at the potential” for landfill mining--and not just for energy and recycling. Several companies with landfill sites near cities are looking to reclaim land for property development, he says. …

The concept of mining landfills has been around for years. In the 1950s, the Israelis took soil enriched with waste and spread it over orchards to improve earth quality of the land. And, in the 1980s, some U.S. states farmed landfill material for use in incinerators.

But it has taken rising energy prices and higher demand for recyclables (notably plastic and metals), to make landfill mining viable for companies like Machiels. That, and government support: A key part of the funding for the Houthalen-Hechteren project is coming from renewable energy credits….

Nampa investigates new energy source

KBOI 2 - Boise, Idaho
Watch the video
NAMPA, Idaho – …Nampa city council has green-lighted a study that looks into turning their garbage into energy.
…Garbage in a special landfill is heated, which speeds up the natural decomposition process. This turns the solid garbage into a gas that can be used to turn a generator and create energy. …
"This technology allows us to take trash thrown off by people who are done with it and produce a sustainable energy supply," Nampa mayor Tom Dale said….
If the city approves the project, supporters say 90 percent of the trash that ends up in the county landfill would instead be used to make energy. …

Trash Inc: The Secret Life of Garbage

CNBC

Watch the FULL PROGRAM

ABOUT THE SHOW

Garbage. It's everywhere — even in the middle of the oceans — and it's pure gold for companies like Waste Management and Republic Services who dominate this $52 billion-a-year industry. From curbside collection by trucks costing $250,000 each, to per-ton tipping fees at landfills, there's money to be made at every point as more than half of the 250 million tons of trash created in the United States each year reaches its final resting place.
Current landfill gas projects in the United St...Image via WikipediaAt a cost of $1 million per acre to construct, operate and ultimately close in an environmentally feasible method, modern landfills are technological marvels — a far cry from the town dump that still resonates in most people's perceptions. Not only do they make money for their owners, they add millions to the economic wellbeing of the towns that house them. Technologies, such as Landfill Natural Gas and Waste To Energy, are giving garbage a second life, turning trash into power sources and helping to solve mounting problems. It's particularly important in places like Hawaii, where disposal space is an issue, and in China, where land and energy are needed and trash is plentiful.
One sure thing about the garbage business: it's always picking up.

PROGRAM HIGHLIGHTS

When a ton of trash is delivered to a waste-to-energy plant, several things happen: the energy content of the waste is retrieved, metals are recovered and recycled and electricity is generated….
EPA's Municipal Solid Waste Decision Support Tool has demonstrated that a modern waste-to-energy plant provides for the avoidance of greenhouse gases through three different operations:
  • For every megawatt of electricity generated through the combustion of solid waste, a megawatt of electricity from conventional, e.g., coal or oil-fired, power plants is avoided, creating a new savings of emissions of greenhouse gases, i.e., carbon dioxide.
  • A modern municipal waste-to-energy facility separates ferrous and/or nonferrous metals for recycling. This is more energy efficient than mining virgin materials for the production of new metals such as steel. As a result, there is a significant energy savings and additional avoidance of greenhouse gas emissions.
  • Comparison of greenhouse gas emissions for mun...Image via WikipediaWhen a ton of solid waste is processed in a waste-to-energy facility, the methane that would have been generated if it were sent to a landfill is avoided. … Methane is a potent greenhouse gas, i.e., twenty-three times more potent than carbon dioxide.
In addition to the analysis using EPA's Decision Support Tool, a detailed, project analysis of a facility's contribution to solving the threat of global warming has been completed for a 1500-ton-per-day waste-to-energy facility in Saugus, Massachusetts.  The study determined about 270,00 tons of carbon dioxide equivalent emissions are avoided annually because of this one waste-to-energy plant's operations. …

In addition, the newly formed Global Roundtable on Climate Change (GROCC) unveiled a joint statement on February 20, 2007 identifying waste-to-energy as a means to reduce carbon dioxide emissions from the electric generating sector and methane emissions from landfills. This important recognition from the GROCC, which brought together high-level, critical stakeholders from all regions of the world, lends further support that waste-to-energy plays an important role in reducing greenhouse gas emissions.
History of municipal solid waste generation an...Image via WikipediaThe breadth of support for the GROCC position is evidenced by those that have signed the joint statement, including Dr. James Hansen of the NASA Goddard Institute for Space Studies and David Hawkins of the Natural Resources Defense Council's Climate Center, as well as entities as diverse as General Electric, Florida Power and Light, and Environmental Defense Fund.

China’s Clean Tech Boom

Worldwide Renewable energy, existing capacitie...
 Image via Wikipedia

 

Bruce Usher, the former CEO of EcoSecurities, describes China’s path to leadership in renewable energy.

strategy+business magazine
by Laura W. Geller
China is fast becoming a clean technology leader. By 2008, it had become the world’s leading producer of solar panels, and last year it claimed the same title for wind turbines. Investment in clean tech in China in 2009 reached US$34.6 billion, compared with the United States’ investment of $18.6 billion. Bruce Usher, formerly the CEO of EcoSecurities Group PLC, a company that sources, develops, and trades carbon offsets from greenhouse gas emissions reduction projects, and now an adjunct professor of finance and executive in residence at Columbia Business School, has observed China’s growth in this sector firsthand. … Usher spoke with strategy+business in May about what he witnessed, what he learned, and what he sees as the future of clean tech in China and other emerging economies.
S+B: What did you observe on the ground as your business grew in China?
USHER:
… What we found was that the industrial policy established by the Chinese government through the NDRC [National Development and Reform Commission] was very effective at stimulating development within the private sector. In our case, that meant stimulating the construction of clean energy projects, primarily small hydro and wind projects. Once the policies were in place, the private sector moved quickly. The banking sector tended to be quite supportive as well, in terms of availability of capital and attractive rates.
S+B: What are some of the unique benefits and challenges that China presents?
USHER:
Based on my experience watching the way the clean tech industry has evolved in China, I’m convinced that the challenge of reducing carbon emissions is less about innovation and more about implementation. …[In] the U.S., for example, they are not getting implemented, or they are not getting implemented quickly enough. That’s where I was particularly impressed with my experience in China: There was an ability to get things done fast, and on a massive scale.
Because the Chinese government is more involved in industrial policy, it sets rules that are supportive, but that can also be restrictive. … We encountered some other fairly technical challenges working in China, but those were more than offset by the fact that things tended to get done very quickly as long as we worked within China’s strict regulations.
S+B: What does the future of clean technology in China look like?
USHER
: …[The] big picture is they’re building massive numbers of coal-fired power plants as well, which produce an enormous amount of pollution, and that’s simply because they have such voracious demand for energy. They have to build these plants, or at least they believe they have to build them, to meet this demand. But the amount of hydro and wind development in China has also been massive for the last couple of years, and it’s very clear they will continue to grow this area in the years to come. The level of expertise coming out of China is only going to get higher. I see enormous development in the sophistication of the products being made in China, and I see more and more local development there, as well.
Looking ahead, something else interesting is happening in China with electric cars and battery technology. The country has experienced rapid growth in transportation infrastructure, and in some ways has a competitive advantage — the U.S. already has an infrastructure based on gasoline-powered vehicles, but because China’s is still developing, it is easier to make the transition to electric. We already see electric-powered two-wheeled vehicles everywhere in China, and I would be surprised if cars were far behind.
S+B: Do opportunities exist for other emerging economies to make a name for themselves in clean tech?
USHER:
Emerging economies have one huge advantage over developed countries. To explain, I’ll use a cell phone example. Americans who travel to the developing world are often shocked by how well their cell phones work there. …[That’s] because these countries went straight to mobile, without a landline step in between. There are more cell phones in Africa than there are in North America today. …[We’re] talking about very simple phones. But cell phone coverage is ubiquitous in the developing world.
So if that can happen in cell phones, there’s reason to think that in clean energy or renewable energy, similar forces may be at work. Because their energy infrastructure is often very poor to begin with, and because there’s rapid growth and demand for energy, developing countries can leapfrog the sort of dirty, traditional energy that we have in our infrastructure in the United States. Similar to the electric car example above, they can go straight from no energy to clean energy, and that’s a huge advantage because clean energy is still more expensive than dirty energy, but incrementally so, and if you’re going from zero to building something, you might be willing to make that incremental investment. Here in the U.S., if we have to scrap our current infrastructure, that’s a huge additional cost. We need to start all over again, and that’s a big challenge.
Sugar cane residue can be used as a biofuelS+B: Besides China, what emerging economy is making notable progress?
USHER:
I think Brazil, … is an interesting example. What Brazil’s leaders recognized more than 20 years ago is that their country had a competitive advantage in its ability to produce cane sugar due to geography and expertise, and that it could convert that Image via Wikipediainto an energy product — ethanol — at a competitive price.
Building on that success, I think Brazil is taking some fairly innovative approaches to managing the resources of the Amazon. … Deforestation still goes on, no question about it, but the rate of deforestation has slowed significantly in the last couple of years, and government initiatives have contributed greatly to this improvement. Now, it’s not necessarily clean tech, but in many ways, it’s addressing a similar problem. It’s addressing climate change in a way that’s specific to Brazil.
