Energy Efficiency Is Key to Achieving Carbon Pollution Standard

Right now, there are no limits on carbon pollution from power plants, even though these facilities were responsible for  roughly 40 percent of all U.S. carbon dioxide (CO2) emissions in 2012.

That’s why the Environmental Protection Agency (EPA) is crafting greenhouse gas (GHG) regulations for new fossil fuel-fired power plants by setting a limit on how much CO2 the plants can emit. Later this year, EPA will issue proposed CO2 “emission guidelines” for existing fossil fuel-fired power plants using various Clean Air Act tools to protect human health and to clean up our air.

To achieve significant and cost-effective emission reductions from existing power plants, EPA should look to leading states that are already implementing successful measures to reduce emissions. These measures include investing in renewable energy, harvesting energy efficiency, and utilizing more efficient and lower-emitting fossil fuel-fired units. Read More »

Haze over Dallas Area

Last week, EDF took one more step toward protecting Texans from harmful levels of ozone pollution that have afflicted the state for far too long.

Ozone pollution, better known as “smog,” is one of the most severe and persistent public health problems affecting Texans.  Smog causes a range of health issues — including aggravation of asthma and other respiratory illnesses, decreased lung function, increased hospital and emergency room visits for respiratory conditions — and it is associated with premature mortality in urban areas.

According to the American Lung Association (ALA), Dallas-Fort Worth is the eighth most affected area in the country for smog.  ALA estimates the city is home to millions of people who are sensitive to ozone-related health problems — including 1.6 million people suffering cardiovascular disease; nearly 1.9 million children; nearly 650,000 elderly residents; and over 520,000 people with asthma.

EDF and its dedicated staff in Texas have long worked to protect Texans from unhealthy levels of smog by reducing the pollution that leads to harmful ozone levels.  Most recently, we have been litigating in the United States Court of Appeals for the District of Columbia Circuit to secure important Clean Air Act protections in all areas that are contributing to the serious ozone problems in Dallas-Fort Worth.  Read More »

We Can’t Expect a Reliable Energy Future Without Talking Water

By Kate Zerrenner / Published: January 14, 2014

This commentary originally appeared on our EDF Voices blog.

It’s no secret that electricity generation requires substantial amounts of water, and different energy sources require varying amounts of water. Nor is it a surprise that Texas and other areas in the West and Southwest are in the midst of a persistent drought. Given these realities, it is surprising that water scarcity is largely absent from the debate over which energy sources are going to be the most reliable in our energy future.

Recent media coverage has been quick to pin the challenge of reliability as one that only applies to renewables. The logic goes something like this: if the sun doesn’t shine or the wind doesn’t blow, we won’t have electricity, making these energy sources unreliable. But if we don’t have reliable access to abundant water resources to produce, move and manage energy that comes from water-intensive energy resources like fossil fuels, this argument against the intermittency of renewables becomes moot.

Moving forward into an uncertain energy future, the water intensity of a particular electricity source should be taken into consideration as a matter of course.  Read More »

Cost Savings Aren’t the Only Benefit to Energy Efficiency

By Kate Zerrenner / Published: January 9, 2014

Kate ZerrennerThis commentary originally appeared on our Texas Clean Air Matters blog.

I often refer to energy efficiency as being cost effective, and it is. It is always cheaper not to use energy or to get the same result while using less energy. But monetary cost savings are just one of the many benefits associated with implementing energy efficiency measures. Reduced pollution, improved health and reduced strain on our water supply are other notable benefits of energy efficiency, though they are not always taken into consideration when a utility proposes a new energy efficiency project.

At the state regulatory level, Public Utility Commissions or similar entities are required to do a cost-benefit analysis for each energy efficiency project or program that a utility proposes, in order to determine how cost effective it may be. This analysis is called an ‘energy efficiency cost test,’ and although the concept may seem straight forward, its application is based on a varying set of pre-defined criteria that are not always consistent. Furthermore, the subject of cost-effectiveness tests is sensitive in the utility sector, because it’s at the core of how energy efficiency programs are valued.

There are several different types of energy efficiency cost tests that differ slightly and are often customized to reflect a state’s values. Before diving into the options, it’s important to note that a cost-effectiveness test of some sort is a necessary measure as more and more states implement ratepayer-funded energy efficiency programs. Customers need to know that the programs they’re paying for are delivering the promised benefits, and regulators need to ensure that the costs paid by the customers are justified.  Read More »

Demand Response Helps Texas Avoid Rolling Blackouts in the Face of Polar Vortex

By Marita Mirzatuny / Published: January 8, 2014

This commentary originally appeared on our Texas Clean Air Matters blog. 

As we begin a new year, the outlook for 2014 looks bright.  But as the Polar Vortex has descended upon the U.S. over the last few days, we have been reminded of the past, specifically the winter of 2011 when Texas’ electricity grid stuttered under the extreme cold.

Monday, as a record-breaking cold snap whisked over the U.S., the Electric Reliability Council of Texas (ERCOT), the state’s grid operator, warned of possible blackouts, just as they did in 2011.  We were lucky this time, but in February of 2011 we were not, and blackouts occurred throughout the state.

ERCOT’s warning meant that the grid’s power reserves “dropped below a comfortable threshold,” and the “system was just one step away from rolling blackouts” as the need for energy outpaced supply.  As these blackout threats loomed, two power plants succumbed to the cold and went down.  The loss in capacity amounted to about 3700 megawatts (MW), with 1800 MW lost due to the cold.  According to Dan Woodfin, ERCOT’s Director of System Operations, “if we had lost another unit it would have put us into an Energy Emergency Alert Three” – the stage that prompts rolling blackouts.  This is unnecessary and unacceptable.

Renewable Energy to Thrive in 2014, Despite ALEC’s Aggressive Tactics

By Marita Mirzatuny / Published: January 3, 2014

Marita MirzatunyNow that 2013 is behind us, it’s important to reflect on the progress of renewable energy last year and identify obstacles that may arise in 2014.

Over the last year, we kept a close eye on multiple clean energy attacks around the country, specifically on the Renewable Portfolio Standards (RPS) in the various states.  As we have highlighted before, the “man behind the curtain” in these attacks is none other than the infamous American Legislative Exchange Council (ALEC), a front group and model bill factory for many corporate interests including oil, gas and coal.

The good news is that from Ohio to Kansas, EDF and other organizations have been successful in preventing ALEC’s aggressive tactics to hamper clean energy.  To date, ALEC has failed to repeal clean energy standards in any state, despite its “Electricity Freedom Act” propaganda and promise that 2013 would be “the most active year ever” for efforts to repeal renewable energy mandates.  Active?  Yes.  Effective?  No.   Read More »
