The Many Benefits of Reducing Carbon Pollution from Existing Power Plants

By Megan Ceronsky / Published: May 15, 2014

The newly-released Third National Climate Assessment has some eye-opening news about climate change.

The report confirms that if greenhouse gas emissions are not reduced it is likely that American communities will experience:

  • increased severity of dangerous smog and particulate pollution in many regions[1]
  • intensified precipitation events, hurricanes, and storm surges[2]
  • reduced precipitation and runoff in the arid West[3]
  • reduced crop yields and livestock productivity[4]
  • increases in fires, insect pests, and the prevalence of diseases transmitted by food, water, and insects[5]
  • increased risk of illness and death due to extreme heat[6]

Extreme weather imposes a high cost on our communities, our livelihoods, and our lives.  The National Climatic Data Center reports that the United States experienced seven climate disasters that each caused more than a billion dollars of damage in 2013, including the devastating floods in Colorado and extreme droughts in western states.[7]

These are precisely the type of impacts projected to affect American communities with increasing frequency and severity as climate-destabilizing emissions continue to accumulate in the atmosphere.

Fossil fuel-fired power plants are far and away the largest source of greenhouse gas emissions in the United States, emitting more than two billion metric tons of carbon dioxide in 2012 — equivalent to 40 percent of U.S. carbon pollution and nearly one-third of total U.S. greenhouse gas emissions.[8]

Yet there are currently no legal limits on the amount of carbon dioxide power plants can release into the atmosphere.

This June, the Environmental Protection Agency (EPA) will, at long last, propose Carbon Pollution Standards for existing power plants.

The solutions we need to achieve significant reductions of carbon pollution from our nation’s largest source are at hand — including changes at existing power plants to reduce emissions, shifting utilization towards lower-polluting generation and away from higher-polluting generation, and deploying renewable energy and energy efficiency.

The health-improving, cost-saving, job-creating benefits of these proven techniques should be shouted from the rooftops.

States and power companies are already capitalizing on opportunities to reduce carbon pollution and other health-harming air pollutants by switching to lower-emitting generation.

Look, for example, at Colorado.

The Clean Air-Clean Jobs Act, which passed with bipartisan support and was signed by Governor Bill Ritter in 2010,[9] will significantly improve air quality while ensuring a reliable supply of electricity.

Under the Act, Xcel Energy plans to replace aging, high-emitting coal-fired units in the Denver metro area with lower-emitting resources, including state-of-the-art efficient combined-cycle natural gas plants that can quickly cycle to complement plentiful wind power and energy efficiency.[10] These changes will help Xcel reduce carbon dioxide emissions from its Colorado fleet by 28 percent by 2020 as well as[11] nitrogen oxide emissions by 86 percent, sulfur dioxide emissions by 83 percent, and mercury emissions by 82 percent.

Reducing emissions of these dangerous pollutants will save lives, reduce the number of nonfatal heart attacks, reduce cases of chronic bronchitis and asthma attacks, and avoid hospital admissions and emergency room visits.[12]

Xcel Energy expects that the projects will inject $590 million into the state’s economy and support 1,500 jobs.[13]

Colorado is also leading the way in renewable energy and energy efficiency.  The state’s renewable energy standard (RES) — which was put in place by a ballot initiative in 2004 — now requires investor-owned utilities to supply 30 percent, and municipal utilities and cooperatives to supply 10 percent, of their retail sales with renewable energy by 2020.[14]  Colorado’s energy efficiency resource standard (EERS) sets a goal for investor-owned utilities of 5 percent savings of 2006 peak demand by 2018 through demand-side management programs for their customers.[15]

The RES is expected to avoid 30 million tons of carbon dioxide emissions, create more than 30,000 jobs, and generate $4.3 billion in economic output.[16]

As for energy efficiency, in 2013 Xcel’s demand-side management plan saved 384.2 gigawatt hours of electricity (exceeding the goal approved by the Public Utilities Commission)[17] and avoided more than 280,000 tons of carbon dioxide and close to 230,000 pounds of sulfur dioxide from electricity generation.[18]

Renewable energy has taken off in recent months and years, replacing higher-emitting sources of energy and creating jobs.  Between 2011 and 2013, wind generation in the United States increased by 40 percent,[19] and in January 2014, the United States had a record month for wind power with generation of nearly 18,000 gigawatt hours.[20]

Xcel Energy recently announced 700 megawatts of new wind energy in New Mexico, Oklahoma, and Texas, which it estimates will save customers up to $590 million in fuel costs.[21]  Xcel says it is adding wind capacity “purely on economics and the savings we can deliver to our customers,” as the price of energy from the new facilities will be less than that from the company’s natural gas-fired plants.[22]

Solar power is on the rise as well.  In 2012, rooftop solar panels cost approximately one percent of what they did 35 years ago,[23] and the cost of solar panels fell by 60 percent from 2011 to 2013.[24]  Since 2008, as the cost of a solar module dropped from $3.40 per watt to 80 cents per watt, solar deployment has jumped by about 10 times.[25]  In 2013 alone, solar photovoltaic installations increased by 41 percent, to a record 4.75 gigawatts, outpacing the industry’s own projections.[26]

Utilities and their customers are also seeing the advantages of solar energy. In March 2014, Austin Energy bought 150 megawatts of solar power at a price just below five cents per kilowatt hour — one of the lowest prices for solar yet which will likely lower rates.[27]  And solar produces high-quality jobs, too, with the industry employing about 143,000 Americans at the end of 2013 and surpassing growth expectations for that year.[28]

Along with renewables, energy efficiency will play a key role in reducing carbon pollution while at the same time saving businesses and families money on their energy bills and creating high-paying jobs.

A recent report by the American Council for an Energy-Efficient Economy lays out several policies that states could use to meet their carbon-reduction goals, including energy-efficiency targets, building codes, appliance standards, and new combined heat and power systems.[29]  If adopted, in the year 2030 these policies could:

  • reduce emissions of carbon dioxide by about 600 million tons, of sulfure dioxide by about 980,000 tons, and of nitrogen oxides by about 527,000 tons[30]
  • save 925 million megawatt hours of electricity in 2030,[31] avoiding about $48 billion in energy costs[32]
  • and support 611,000 jobs, creating 6.2 million job-years from 2016 to 2030.[33]

Energy efficiency not only offers a cost-effective way to reduce pollution and positively impact the economy, but also improves comfort and health, increases productivity, and cuts utility bills for homes and businesses, savings that can be spent on other goods and services.[34]

Several organizations have outlined approaches to reducing carbon pollution under the Clean Air Act, and their analysis shows that the Carbon Pollution Standards can protect the climate while at the same time reducing emissions of other dangerous air pollutants.  For example, NRDC estimates that its proposal would reduce harmful sulfur dioxide and nitrogen oxide emissions, saving thousands of lives, preventing 17,000 asthma attacks per year, and avoiding more than 1,000 emergency room visits and hospital admissions per year.[35]

Similar health benefits would be provided by Clean Air Task Force’s proposed framework, which would avoid 446,000 tons (31 percent) of sulfur dioxide and 402,000 tons of nitrogen oxide (24 percent) emissions relative to the base case by 2020.[36]

And Resources for the Future projects co-benefits from sulfur dioxide reductions ranging from $17 billion to $22 billion in 2010 dollars by 2020.[37]

Moving forward under the President’s Climate Action Plan to address carbon pollution from power plants couldn’t be more urgent.  In addition to the reductions in harmful air pollution discussed above, the National Climate Assessment explains that without abating climate change:

“Summers are longer and hotter, and extended periods of unusual heat last longer than any living American has ever experienced. Winters are generally shorter and warmer. Rain comes in heavier downpours. People are seeing changes in the length and severity of seasonal allergies, the plant varieties that thrive in their gardens, and the kinds of birds they see in any particular month in their neighborhoods.

“Other changes are even more dramatic. Residents of some coastal cities see their streets flood more regularly during storms and high tides. Inland cities near large rivers also experience more flooding, especially in the Midwest and Northeast. . . . Hotter and drier weather and earlier snowmelt mean that wildfires in the West start earlier in the spring, last later into the fall, and burn more acreage. . . .”

An upcoming blog will take a closer look at climate change and its impacts on public health in the U.S.  First, though, we will highlight some of the many successes states and power companies have had in deploying clean energy and energy efficiency, and explain the legal foundations for Carbon Pollution Standards that build on this experience and support the expansion of clean energy and energy efficiency programs.

These investments will not only cut emissions of carbon and other pollutants, but also provide homegrown energy, create jobs, and cut utility bills for American homes and businesses.  This is the right path forward for our communities, our kids, and our economy.

President Obama Goes to Walmart

By Elizabeth Sturcken / Published: May 13, 2014

I never really expected to be sitting in a Walmart in Mountain View, CA listening to President Obama speak about environmental commitments, but I am excited for the momentum he is generating, particularly in the private sector, to support the EPA announcement on carbon limits on June 2nd.

So why Walmart?

The President is making a point. Walmart gets about 25 percent of its global electricity from renewables. In the United States over all, only about 2 percent of power comes from solar sources. In 2005, Walmart set a goal to be supplied 100 percent by renewable energy. To date Walmart has 335 renewable energy projects underway or in development across their global portfolio. Having the president hold Walmart up as a role model is a great way to drive other industry leaders to follow suit.

Obama Walmart

This recognition is great news to EDF since we are a key NGO partner to Walmart and have been working with them on environmental solutions since 2005. (See the full EDF – Walmart partnership timeline). In 2008, EDF and Walmart announced a jointly-developed clean energy project to install and assess next generation solar technology at over 30 Walmart facilities. Today Walmart has 250 solar energy systems installed in the U.S. and has a solar energy capacity of 65,000 kW, top of the Solar Energy Industries Association rankings of U.S. companies.

Are industry leaders following suit?

The private and public sector commitments announced today represent more than 850 megawatts of solar deployed – enough to power nearly 130,000 homes – as well as energy efficiency investments that will lower bills for more than 1 billion square feet of buildings. Additionally, the President announced new executive actions that will lead to $2 billion in energy efficiency investments in Federal buildings.

We are especially excited to see companies step up for the President’s Better Buildings Challenge which will improve energy efficiency of more than 1 billion square feet of new floor space by 20 percent by 2020. New to the President’s roster are General Motors (committing 84 million square feet), MGM Resorts (78 million square feet) and Walmart (850 million square feet).

See the complete listing of private and public sector organizations making commitments today for solar deployment and energy efficiency.

Here at EDF, we believe that companies and business leaders must pave the way to a low-carbon and prosperous economy. Today Walmart committed to double the number of onsite solar energy projects at U.S. Stores, Sam’s Clubs and distribution centers by 2020. This is in addition to their goal of reducing greenhouse gas emissions in their global supply chain by 20 million metric tons by the end of 2015.

We think President Obama’s making his announcement at Walmart today was a clear signal to the public and private sector that business needs to step up and publicly commit to ambitious environmental goals. Walmart continues to do this, and we look forward to many other industry leaders following suit.

Hundreds of Thousands Support Standards to Ensure a Healthy Low-Carbon Future

By Mandy Warner / Published: May 9, 2014

This is a fact that always stuns people:

There are currently no national limits whatsoever on carbon pollution from U.S. power plants, the single largest source of this pollution in the country.

But last year, the Environmental Protection Agency (EPA) announced a proposal that could change that fact for future power plants.

EPA’s proposal would set America’s first-ever national carbon pollution standards for future power plants – a major victory in the fight against climate change.

The Carbon Pollution Standards for New Power Plants are an absolutely necessary, common sense step toward limiting the pollution emitted through our country’s power generation. These standards will help protect our children from harmful smog, curb respiratory problems, and shield our communities from extreme weather. They will also drive innovation, so that America can continue to lead the world in the race to develop cleaner, safer power technologies and infrastructure.

About 300,000 EDF activists have sent comments to EPA in support of these vital standards.

(The comment period for these proposed standards ends today — but you still have a few hours to comment, if you haven’t yet! You can write a comment here)

The Carbon Pollution Standards for New Power Plants also have the support of millions of other Americans including moms, and members of health groups, environmental groups, power companies, Latino groups, the NAACP, faith groups and many more.

Here are just a few examples of what people have been saying about the proposed standards:

American Academy of Pediatrics

Children represent a particularly vulnerable group that is likely to suffer disproportionately from both direct and indirect adverse health effects related to climate change. … Because of their physical, physiologic, and cognitive immaturity, children are often most vulnerable to adverse health effects from environmental hazards. Environmental hazards may shift as the climate changes, and children are likely to suffer disproportionately from those changes.

The Clean Energy Group

EPA’s proposed rule for new sources provides the industry with a higher degree of business and regulatory certainty. Based on our review of the proposal, recent projections by the U.S. Energy Information Administration, and current market dynamics, we do not anticipate that the proposed greenhouse gas performance standards for new sources, with the recommendations included here, would adversely affect the reliability of the electric system…We agree that EPA has sufficient scientific and legal basis to regulate greenhouse gases from new EGUs under section 111 of the CAA.

U.S. Conference of Mayors

Over 1,000 mayors have signed USCM’s Climate Protection agreement…But local governments alone cannot shoulder the entire burden or responsibility of limiting GHG emissions and protecting the health of our citizens. A national regulatory framework is required to achieve the substantial and absolutely necessary reduction in GHG emissions. Therefore, we commend the U.S. EPA for its efforts in this regard and encourage final promulgation of these CAA rules.

National Latino Coalition on Climate Change and Green Latinos

It is because Latino and other traditionally under-represented communities are so disproportionately impacted by these harmful pollutants that NLCCC must urge the EPA to adopt the strictest possible carbon pollution standards for new power plants that will adequately protect our communities…These rules are essential to protect the health of our members and necessary to guarantee the safety of the air of Hispanic communities nationwide.

Creation Justice Ministers

I am here today to offer our faith community’s response to the rule on new power plants. We view climate change as the moral issue of our time, and feel we have an obligation to reverse the implications of our careless actions. As Christians, we are called to be stewards of the land that was gifted to us and ensure that we leave this planet better for the next generation.

(You can read more quotes on our fact sheet)

These standards are an important part of President Obama’s Climate Action Plan to control dangerous carbon pollution, pollution we are seeing all too clearly now that is harming our country and world.

The Third National Climate Assessment released a few days ago finds beyond a reasonable scientific doubt that Americans are being affected by climate change, which is directly affected by the increase of emissions of heat-trapping gasses such as carbon.

The NCA says:

Evidence for climate change abounds …The sum total of this evidence tells an unambiguous story: the planet is warming.

The NCA also finds that Americans now experience respiratory illnesses, heart problems, and water-borne diseases as a result of climate change.

The costs of climate inaction are already with us, and threaten to increase for our children and grandchildren. But the Carbon Pollution Standards for New Power Plants are an excellent step towards a brighter future, a more sustainable infrastructure, and a stronger nation.

The way forward to kicking our carbon addiction

By Keith Gaby / Published: May 9, 2014

Photo credit: Billy Wilson cc

How would you respond to an upsetting medical diagnosis? Probably first with shock and fear, then you’d ask the doctor about realistic treatment options. That’s how it works for an individual, but what about when seven billion people get the bad news at the same time?

That’s what happened yesterday, when the White House released another troubling National Climate Assessment (NCA). It described a condition that’s going to get significantly worse without intervention – with troubling symptoms already apparent.

Now, to be fair, this NCA wasn’t really news in the “I didn’t see that coming” sense. Just like a patient who has been told to stop smoking for years, there has been plenty of warning that our “unfiltered” smokestacks are causing serious damage to our environment and health. Last month, in fact, the International Panel on Climate Change issued its fifth report, and this is the third National Climate Assessment – each making more specific estimates of the climate dangers ahead. And yet, we can’t quit our pack-a-day habit.

The disturbing news is all here: Threats to agriculture from drought, danger for coastal residents and businesses from rising seas, more frequent intense hurricanes, more asthma attacks for kids, the spread of insect borne disease, and much more.

But the good news is that this disease has a cure. In fact, in just about four weeks, the United States is poised to take a very important step towards improving the currently predicted outcome. On June 2, EPA is planning to announce limits on carbon emissions from existing power plants, which are America’s largest source of climate pollution – about a third of the total we produce.

When EPA announces the new standards, what will probably surprise most people is that the agency doesn’t already have limits on this type of pollution. A recent poll indicates that 56% of Americans assume we currently have these protections. That’s an understandable belief since EPA limits most other forms of air pollution, but up to now utilities have been free to put as much of this stuff as they can crank out in our common atmosphere. And all that pollution has a very real cost borne by society.

Of course, as with all other proposed air pollution rules, there will be a small but powerful group who howl in protest. They did it when EPA limited toxic mercury, sulfur, smog and other dangerous pollutants. I’m sure you’ll hear that ending unlimited carbon pollution will wreck our economy and bankrupt us all. But what those people won’t tell you is that studies have shown that every past air pollution rule has actually helped the U.S. economy, with benefits outweighing costs by a substantial margin.

The new rules alone won’t cure climate change. But, along with actions on cars and trucks that have already been announced, they are a substantial first step. These standards will also push utilities to modernize, help grow clean energy jobs, and give a boost to entrepreneurs who are looking for ways to power our economy more cleanly. (EPA Administrator Gina McCarthy has said the agency is exploring ways to make the rules flexible, allowing states and companies to find innovative ways to meet the standards.)

Cures are never painless, but they’re usually a lot better than the disease. And everyone knows that the sooner you act, the better the outcome. So let’s take yesterday’s diagnosis seriously, and when EPA announces the new carbon standards on June 2, let’s make sure Congress knows we all want a healthy future.

Trucks delivering six miles per gallon won’t work in the long haul

By Jason Mathers / Published: May 8, 2014

Here’s something to think about next time you are stuck in traffic next to an 18-wheeler: The average tractor-trailer can travel only six miles per gallon of diesel.

These heavy trucks travel a lot too; averaging more than 120,000 miles a year or 20 roundtrip drives between Boston and San Francisco. Freight trucks are on the road for one primary purpose: to get goods to all of us. In fact 70% of U.S. freight tonnage is moved by tractor-trailer trucks. Over the coming years, demand for freight services is expected to grow even more. And this is driving up fuel consumption and greenhouse gas emissions.

A call for strong fuel efficiency standards

But it is possible and affordable for tractor-trailer trucks to get nearly 11mpg by 2025. The Obama Administration can set new fuel efficiency and greenhouse gas standards for heavy trucks that cut fuel consumption by 40% compared to 2010 levels. These standards would also apply for heavy-duty work trucks, such as box delivery trucks, bucket trucks, beverage delivery trucks and refuse trucks.

Strong, new fuel efficiency and greenhouse gas standards for our nation’s heavy trucks are achievable, cost-effective and critical to cutting greenhouse emissions and fuel consumption – all while we continue to depend on trucks to deliver the goods we need and want. The slideshow below highlights some of the technology available to meet bold standards as well as the significant cost, oil and emissions savings from such standards.

Bold fuel efficiency standards are good for our economy, environment and energy security. One fact that just jumps out at me is this: These standards will cut our oil consumption by 1.4 million barrels a day. That sounds like a big number and it is. It’s a bit higher than the amount of oil we import daily from Saudi Arabia.

They will also be good for trucking fleets too. These trucks will cost $30,000 less to fuel a year.

Strong fuel efficiency and greenhouse gas standards for heavy trucks are an important part of the President’s Climate Action Plan, and EDF will continue to work towards strong standards through our unique combination of industry engagement, regulatory design expertise and technical know-how.

New report: How climate change is impacting where you live

By Ilissa Ocko / Published: May 7, 2014

The National Climate Assessment (NCA) report, prepared by the U.S. Global Change Research Program, is essentially the U.S. equivalent of the Intergovernmental Panel on Climate Change (IPCC): Using the best available science, over 300 experts synthesized current understanding of observed and future climate changes and impacts, particularly in the U.S. The third ever NCA was released today, and concludes beyond a reasonable scientific doubt that Americans are being affected by climate change.

Among the findings:

  • U.S. average temperatures have increased by 1.3 to 1.9ºF since record-keeping began in 1895, and most of this warming has occurred since 1970
  • Heavy precipitation has increased in many parts of the country
  • Extremes such as heat waves, droughts, floods, and North Atlantic hurricanes are more frequent and/or intense
  • Summer sea ice in the Arctic has halved since record-keeping began in 1979
  • Sea level rise has increased coastal erosion and storm surge damage

These changing conditions produce a variety of tangible stresses on society by affecting human health, water resources, agriculture, energy, infrastructure, and natural ecosystems. The particular impacts vary by region, but no corner of the country is immune to the change.

So what’s happening where you live?

Source: National Climate Assessment

Unless we take immediate action to curb our emissions of heat-trapping gases, the foreseeable future will be plagued by further warming and worsening impacts. The good news is that because we know what the cause is, we also know what is needed in order to stabilize our planet. We must come together now—locally, nationally, and internationally—and work towards a better future.
