Washington, DC – Offshore energy exploration and production in the United States is safe and environmentally sound. Over the past 50 years, the U.S. oil and gas industry has developed innovative, 21^st century technologies and exploration techniques that are efficient, pose little threat to the environment, and ensure worker safety.

According to the National Academies of Science, less than 1 percent of the oil found in the North American marine environment comes from oil and gas development. Nearly 60 percent, however, is the result of natural seeps.

Thomas J. Pyle, president of the market-oriented Institute for Energy Research (IER), issued this statement in response to today’s Senate Energy Committee hearing on environmental stewardship and offshore energy production:

“Technology and innovation remains key to delivering more homegrown, job-creating American energy, both onshore and off. The facts and history demonstrate that offshore energy production, with today’s 21^st century technologies, poses little to no threat to our marine environment. In fact, marine life actually flourishes in waters shared with energy infrastructure.

“Unfortunately, a de-facto ban on safe, responsible offshore domestic energy development remains in place today, despite the fact that a clear majority of American people want access to the energy that is rightfully theirs. Advanced technologies currently deployed throughout the western Gulf of Mexico – which help deliver huge amounts of energy to keep our economy fueled and moving each day – are testament to the strides made to ensure environmental safety.

“Last summer the American people spoke, and Congress responded when it retired the nearly 30-year ban. It’s time for this administration to unchain the federal government’s stranglehold on so much of our nation’s job-creating energy resources offshore. Slow-walking this commonsense action could make the next energy crisis pale in comparison to the pain of $4 gasoline working families and small businesses felt during the summer of 2008.”

NOTE: Here is brief overview of some of the advanced, 21^st century offshore energy exploration technologies:

Advanced 3-D seismic and 4-D time imaging technologies: enable offshore operators to locate oil and gas resources far more accurately to necessitate less drilling and allow greater resource recovery.

Storm chokes: placed on all offshore wells to detect damage to surface valves and shut down production during an emergency.

Blowout preventers: continuously monitor the subsurface and subsea-bed conditions to prepare for unexpected changes in well pressure.

Waste product reuse technology: transforms drill cuttings, a waste product of rock pieces and drilling fluids produced when drilling a well, into raw material for bricks, roads, and even rebuilding Louisiana’s wetlands.

Coal-fired electricity generation is far cleaner today than ever before. The popular misconception that our air quality is getting worse is wrong, as shown by EPA’s air quality data. Modern coal plants, and those retrofitted with modern technologies to reduce pollution, are a success story and are currently providing about 50% of our electricity. Undoubtedly, pollution emissions from coal-fired power plants will continue to fall as technology improves.

Executive Summary

America’s improving air quality is an untold success story. Even before Congress passed the Clean Air Act Amendments of 1970, air quality had been improving for decades.[i] And since 1970, the six so-called criteria pollutants have declined significantly, even though the generation of electricity from coal-fired plants has increased by over 180 percent. [ii] (The “criteria pollutants” are carbon monoxide, lead, sulfur dioxide [SO₂], nitrogen oxides [NO_x], ground-level ozone, and particulate matter [PM]. They are called “criteria” pollutants because the EPA sets the criteria for permissible levels. [iii]) Total SO₂ emissions from coal-fired plants were reduced by about 40 percent between 1970 and 2006, and NO_x emissions were reduced by almost 50 percent between 1980 and 2006. On an output basis, the percent reduction is even greater, with SO₂ emissions (in pounds per megawatt-hour) almost 80 percent lower, and NO_x emissions 70 percent lower.

Figure 1 below shows the increases in Gross Domestic Product, vehicle miles traveled, energy consumption, and population since 1980, and it compares them to the decline in the aggregate emissions of criteria pollutants. Today, we produce more energy, drive further, and live more comfortably than we did in the past, all the while enjoying a cleaner environment.

One factor in improving air quality has been the pollution-control technologies used by coal-fired power plants. Today’s coal-fired electricity generating plants produce more power, with less emission of criteria pollutants, than ever before. According to the National Energy Technology Laboratory (NETL), a new pulverized coal plant (operating at lower, “subcritical” temperatures and pressures) reduces the emission of NO_x by 86 percent, SO₂ by 98 percent, and particulate matter (PM) by 99.8 percent, as compared with a similar plant having no pollution controls [xv]. Undoubtedly, air quality will continue to improve in the future because of improved technology.

Today, coal-fired electricity generation produces nearly half of the electricity generation in America and provides many jobs. For example, Prairie State Energy Campus, a 1,600-megawatt coal plant under construction in southern Illinois, provides 1,200 people with jobs in around-the-clock construction. Between its power plant, coal mine, and other assets, the campus will inject some $2.8 billion into the Illinois economy, creating 2,300 to 2,500 temporary construction jobs and 500 permanent positions, while emitting 80 percent less in pollutants than most existing power plants.[iv] When completed, the power plant will deliver electricity to 2.4 million homes in at least nine states.

Background

• Even before Congress passed the Clean Air Act Amendments of 1970, creating the Environmental Protection Agency, air quality was improving. Prior to 1970, business saw certain types of pollution as waste, and worked to reduce them through technological improvements in order to increase efficiency. Furthermore, state and local policymakers worked to reduce pollution.[v]
• The Clean Air Act, last modified in 1990, requires the Environmental Protection Agency (EPA) to set National Ambient Air Quality Standards to control pollutants considered harmful to public health or the environment: these are the so-called criteria pollutants.
• Two of these pollutants, SO₂ and NO_x are the principal pollutants that cause acid precipitation (colloquially known as acid rain). SO₂ and NO_x emissions react with water vapor and other chemicals in the air to form acids that fall back to earth. Prior to controlling for these emissions, power plants produced most (about two-thirds) of the SO₂ emissions in the United States. The majority (about 50 percent) of NO_x emissions came from cars, buses, trucks, and other forms of transportation, with power plants contributing about 25 percent. The remainder came from other sources, such as industrial and commercial boilers.[vi]
• The 1990 changes to the Clean Air Act introduced a permanent cap on the total amount of SO₂ emissions that may be emitted by electric power plants nationwide, thereby reducing the level of these emissions in the atmosphere. The approach used was a cap-and-trade program with a steadily declining cap through 2010.
• In order to comply with the Clean Air Act Amendments of 1990, electric utilities could either switch to low sulfur coal, add equipment (e.g., scrubbers) to existing coal-fired power plants in order to remove SO₂ emissions, purchase permits from other utilities that exceeded the reductions needed to comply with the cap, or use any other means of reducing emissions below the cap, such as operating high-sulfur units at a lower capacity utilization.
• EPA devised a two-phased strategy to cut NO_x emissions from coal-fired power plants. The first phase, finalized in a rulemaking in 1995, aimed to reduce NO_x emissions by over 400,000 tons per year between 1996 and 1999. The second phase began in 2000, and it aimed to reduce NO_x emissions by over 2 million tons per year. The second phase reduction goal was exceeded, owing in part to additional state-initiated NO_x reductions in the Northeast.[vii]
• In 1998, EPA issued a rule that required 21 states and the District of Columbia to further reduce NO_x emissions through the use of newer, cleaner control strategies. The rule gave each affected state a NO_x emission target and let the state determine how to reduce its emissions. The goal was to reduce total emissions of NO_x by 1 million tons in the affected states by 2007. Most states were required to begin reductions in 2004.[viii]
• EPA issues air pollution control standards under the Clean Air Act Extension of 1970. These standards are called New Source Performance Standards (NSPS). EPA’s NSPS require all power plants for which construction commenced after February 28, 2005, to not exceed 1.0 lb/megawatt hour (0.11 lb/million Btu) of NO_x, 1.4 lb/megawatt hour (0.15 lb/million Btu) of SO₂, and 0.14 lb/megawatt hour (0.015 lb/million Btu) of particulate matter (PM). [ix] However, as can be seen below, most new plants are built to more stringent criteria.

Coal Industry Emissions Reduction

• Of the 328,720 megawatts of coal-fired capacity reporting their control technologies to the Energy Information Administration in 2005, 48 percent (158,493 megawatts) have cooling towers, 31 percent (101,338 megawatts) have flue gas desulfurization equipment (scrubbers), and 100 percent have particulate collectors.[x]
• The following graph compares the SO₂ and NO_x emissions from coal-fired power plants divided by the fuel consumed by these plants from 1970 to 2006. Between 1970 and 2006, SO₂ emissions in lbs per million Btu were reduced by almost 80 percent and NO_x emissions in lbs per million Btu were reduced by over 70 percent. Between 1970 and 2006, total SO₂ emissions were reduced by about 40 percent. Between 1980 and 2006, NO_x emissions were reduced by almost 50 percent.



• A study by the National Energy Technology Laboratory (NETL) compared the emission rates from pulverized coal plants and integrated gasification combined cycle plants based on the environmental regulations that would apply to plants built in 2010 using technology designs from several vendors, including General Electric Energy (GEE), ConocoPhillips (CoP), and Shell. These rates are provided in Table 1 for three criteria pollutants: sulfur dioxide, nitrogen oxides, and particulate matter (PM).[xi] The rates range from .0105 to .0848 lbs/million Btu for SO₂, .055 to .07 lbs/million Btu for NO_x, and .0071 to .013 lbs/million Btu for PM, depending on technology type. These emission rates are 43 to 93 percent lower than the current NSPS for SO₂, 36 to 50 percent lower than the current NSPS for NO_x, and 13 to 53 percent lower than the current NSPS for PM. Integrated gasification units have lower criteria pollutants than pulverized coal plants.

• According to NETL, for a new pulverized coal plant (subcritical) built in 2008, pollution controls reduce NO_x emissions 86 percent, SO₂ emissions by 98 percent, and PM by 99.8 percent when compared with a similar plant with no pollution controls. The target emission level for NO_x is 0.070 lb/MMBtu, for SO₂ is 0.085 lb/MMBtu, and for PM is 0.013 lb/MMBtu. Without control technologies, a subcritical coal plant would emit 0.5 lb/MMBtu of NO_x, 4.35 lb/MM Btu of SO₂, and 6.5 lb/MM Btu of PM.[xii] The figure below graphically depicts the criteria pollutants from a new controlled plant vs. a new uncontrolled plant.

Cost Factors in Emission Reductions

• According to the EIA, the costs of adding flue gas desulfurization (FGD) equipment to remove sulfur dioxide are, in 2006 dollars, $301/KW for a 300 MW plant, $230/KW for a 500 MW plant, and $190/KW for a 700 MW plant. The costs for selective catalytic reduction (SCR) equipment to remove nitrogen dioxides are $124/KW for a 300 MW plant, $108/KW for a 500 MW plant, and $98/KW for a 700 MW plant. The costs per megawatt of capacity decline with plant size.  FGD units are assumed to remove 95 percent of the SO₂ and SCR units are assumed to remove 90 percent of the NO_x.[xiii]
• The NETL study provides estimates of both the capital cost and the levelized cost of these technologies, which are given in Table 2 in 2007 dollars.[xiv] The levelized cost is the present value of the total cost of building and operating the plant over its economic life, converted to equal annual payments. The plant costs range from $1,549 to $1,977 per kilowatt for a 550 megawatt plant, with integrated gasification combined cycle technology having the higher costs. The 20-year levelized plant cost was computed using fuel prices from the Energy Information Administration’s Annual Energy Outlook 2007. The levelized plant costs range from 6.33 to 8.05 cents per kWh.

• NETL estimates that for a pulverized subcritical coal plant, the equipment to control NO_x, SO₂, and PM comprises $324/kW of the $1,549/kW plant cost (21 percent). At the request of IER, NETL estimated the cost of a subcritical pulverized coal plant without controls for criteria pollutants. The levelized cost of the new controlled plant is 6.4 cents per kWh and that of the new uncontrolled plant is 5.2 cents per kWh, 19 percent lower. A controlled plant has slightly lower output, less than 1 percent lower, and its capital costs are about 25 percent higher due to the cost of the control technologies.[xv]

Coal-fired electricity generation is far cleaner today than ever before. The popular misconception that our air quality is getting worse is wrong, as shown by EPA’s data.[xvi] Modern coal plants, and those retrofitted with modern technologies to reduce pollution, are a success story and are currently providing about 50% of our electricity. Undoubtedly, pollution emissions from coal-fired power plants will continue to fall as technology improves.

Cap-and-Trade: “Acid Rain” versus Greenhouse Gases

The results of using a cap-and-trade system to fight “acid rain” have led some to argue that it is a model for efforts to reduce carbon dioxide emissions. But the analogy fails. Stark differences exist between the “acid rain” emission-reduction program and the challenge of reducing carbon dioxide, a natural byproduct of combustion, emitted by natural and man-made sources.

Carbon dioxide is emitted in the U.S. by hundreds of millions of sources, including every personal automobile, the appliances many of us use to cook our food and heat our homes, and the businesses upon which we depend for our livelihoods, to name a few. The “acid rain” emission reduction program was initially limited to 110 site-specific utility plants, and then later expanded to 445 plants.[xvii] In addition, carbon dioxide is a world-wide byproduct of combustion, whereas all criteria pollutants are local or regional. In other words, what the United States did for SO₂ and NO_x directly affected air quality here, while national action to limit carbon dioxide emissions will have little bearing on aggregate global emissions.

Furthermore, at the time of the SO₂ and NO_x reduction program, alternative low sulfur coal sources existed and utilities had available affordable and proven technologies to utilities to reduce their emissions. When Congress passed the Clean Air Act Amendments of 1990, therefore, coal-fired utilities could responsibly reduce emissions from their plants using various options that limited cost impacts to the consumer.

In addition, attempts to extrapolate the “acid rain” success story to the challenge of reducing carbon dioxide emissions fail to recognize the history of similar programs in other parts of the world. For example, the “Emissions Trading Scheme” of the European Union has been ineffective at reducing carbon dioxide emissions at the same time it has increased prices and harmed businesses and consumers.[xviii] Further, the EU program has enriched some companies and industries at the expense of consumers.

A recent study by Laurie Williams and Allen Zabel, career employees of the Environmental Protection Agency, makes these points about what the authors call the “Acid Rain Myth.”[xix] As the authors explain, that those who champion the use of cap-and-trade to address global warming ignore the crucial distinctions between the issues we faced in 1990 with acid rain and the issues we face today with global warming.

The following highlights Williams and Zabel’s study demonstrate that the experience of the acid rain program cannot and should not be compared to cap and trade for greenhouse gas emissions:

• “Most importantly, the success of the Acid Rain program did not depend on replacing the vast majority of our existing energy infrastructure with new infrastructure in a relatively short time. Nor did it depend on spurring major innovation. Rather, the Acid Rain program was successful as a mechanism to guide existing facilities to undertake a fuel switch to a readily available substitute, the low sulfur coal in Wyoming’s Powder River Basin.”
• “The goal of the Acid Rain program was to reduce sulfur dioxide emissions, while keeping the cost of energy from coal low. To be effective, climate change legislation must do the opposite; it must gradually increase the relative price of energy from coal and other fossil fuels to create the appropriate incentives for both conservation and the scale-up of clean energy.”
• “Further, the Acid Rain program did not allow any outside offsets and so provides no basis for the widespread assumption that an offset program will help with climate change. In addition, the success of the program was aided by the low, competitive price of low-sulfur coal.”
• “According to Professor Don Munton, author of ‘Dispelling the Myths of the Acid Rain Story’ the impact of the program has been overstated: The potential for a massive switch to low sulfur coal was no secret. Such coal was cheap and available, and it became cheaper and more available throughout the 1980s. Indeed, low-sulfur coal became very competitive with high-sulfur supplied well before the Clean Air Act became law.”

In short, the mechanisms available to reduce pollutants allowed for more generation of energy with less pollution. But this success cannot be extrapolated to the regulation and reduction of carbon dioxide, a much more challenging undertaking. None of the conditions existing at the time of the apparent success of the SO₂ and NO_x reduction program apply to carbon dioxide, and, in any case, unilateral action by the United States will have little impact upon global carbon dioxide concentrations. Indeed, the challenges presented by the control and regulation of carbon dioxide have no parallels in the history of emission regulation.

• Rep. Obey’s Summary of the Bill
  
• Text of the “Green Jobs” Stimulus Bill
• Discussion Draft of the Bill Report
  

The bill is partially based on studies which purport to show large numbers of jobs created by government spending on “green technology” such as energy efficiency and renewable energy projects. IER recently released a study demonstrating that the campaign to sell government ‘green jobs’ as a cure for our economic ills relies on misguided assumptions, unsound data, and false hope.

Among the key findings of IER’s Green Jobs: Fact or Fiction?:

• “[Obama’s green jobs plan] would likely increase consumer energy costs and the costs of a wide array of energy-intensive goods, slow GDP growth and ironically may yield no net job gains. More likely, [it] would result in net job losses.”

• “Although each report [in defense of ‘green jobs’] is unique, a common characteristic is that they all rest on incomplete economic analysis, and consequently greatly overstate the net benefits of their policy recommendations.”

• “[The Center for American Progress] estimates that this “fiscal stimulus” will result in the creation of two million jobs. Yet the CAP methodology treats the $100 billion as manna from heaven; it does not consider the direct and indirect adverse effects (including job destruction) of imposing higher costs on a wide array of energy-intensive industries and thereby raising prices for consumers.”

• “The government doesn’t create wealth simply by taking $100 billion from one group of firms and handing it over to a different group …”

• “After broadly defining the renewable industry, the Council of Mayors study goes on to paint a picture of expanding markets that can only grow further.  In reality, with the single exception of wind, U.S. power production from renewables has stagnated for the past fifteen years.”
