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

Kate Zerrenner

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 »

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

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

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 »

Texas is a Leader in Clean Energy Jobs. Let’s Keep It that Way.

Over the past several years, a combination of market forces and targeted policies has brought about enormous growth in clean energy technologies around the United States. A clean energy economy has developed around these new technologies, creating tens of thousands of homegrown jobs each year. Despite the industry’s initial surge, recent economic uncertainty has led to a plateau in clean energy job growth in most, but not all, regions in the U.S.

According to a report released by Environmental Entrepreneurs, the U.S. created 10,800 clean jobs in the third quarter of 2013, down from 37,000 in the previous quarter.

Notably, Texas doesn’t follow the national trend. Texas clean energy companies created over 660 jobs in the fall quarter of 2013 alone, up from less than 500 jobs in the previous quarter, cementing Texas in the list of top 10 states for clean energy jobs. Read More »

Fossil Fuel Industry and Koch Brothers Align to Kill Extension of Wind Energy Tax Credits

Jim Marston, Environmental Defense, Austin, TXIt seems that every year, renewable energy advocates are forced to respond to some false claims made by oil or coal interest groups trying to mislead the public and legislators into believing that solar and wind energy are not worth supporting.  Even though wind power is a clean, renewable, homegrown form of energy that is good for people, business and the environment, fossil fuels are simply hardwired into this country’s DNA.  So it is not surprising that fossil fuel companies defend their subsidies and tax breaks and don’t want clean energy competitors to cut into their support.  

Around this time last year, renewable energy advocates were announcing good news – the production tax credit that helped spark remarkable growth in America’s wind energy industry had been extended through 2013.  And it amounted to more than just a one year bump.  Because the extension applied to projects begun in 2013, rather than completed in 2013, the credit could be applied to more projects over a longer period of time.  Read More »

Is SONGS Haunting Energy’s Past, Present and Future?

Earlier this year, Southern California Edison (SCE) permanently retired the San Onofre Nuclear Generating Station (SONGS) after forty years of operation in San Diego County, appearing to put the large-scale power plant firmly in the past. However, much like Ebenezer Scrooge, California is grappling with the specter of SONGS’ past – which may haunt our present and future.

The story of SONGS is not unique to California. As of the end of 2012, 28 nuclear power plants were shut down in the United States – and many more will face the same fate in the near future, as they reach the end of their design life. Thus, a transition to renewables and incentivizing reduced demand– and a refusal to be tied to fossil fuels – is an issue of national importance.

The closure of SONGS has left California at an important crossroads: Continue to lean on fossil fuel energy and build additional combustion power plants– like Marley’s ghost chained to the past – or start shaping the future by using the clean solutions that are available today. Read More »
