To Unlock Wind, Build Transmission Lines Linking the Plains to the Cities

Guest Author: Robert Fares, Mechanical Engineering Ph.D. student at the University Texas at Austin

This commentary originally appeared on Scientific America's Plugged In blog. 

A vital factor affecting the economics of any energy source is transportation: where is the fuel extracted, where is it used, and how does it get from point A to point B?

An example is the case of Texas versus North Dakota, both of which have experienced a boom in oil and gas production from shale since the introduction of hydraulic fracturing.

Texas, with its long history of oil and gas development, is riddled with underground oil and gas pipelines connecting remote areas of the state with regional trading hubs. Read More »

Earlier this month, Texas Public Utility Commission (PUC) chairwoman Donna Nelson called for the federal government to end its renewable energy tax credit for Texas wind and for the end of state policies that have resulted in Texas’ clean energy economy boon. The chairman’s appeal is so devoid of a factual basis it is hard to conclude that this is anything other than part of an orchestrated campaign by fossil fuel interests to stop the growth of renewable energy. Like the other attacks on clean energy, this is more politics than substance.

The federal and state policies that Chairman Nelson wants to eliminate have been great for Texas. Texas ranks first in the nation for wind-related jobs, employing over 8,000—and many of those jobs are keeping agriculture-heavy West Texas and Panhandle communities afloat amid the devastating multi-year drought. Plus, 60% of all wind projects under construction across the country in the first quarter of 2014 were in Texas. And studies (including one produced by the Texas PUC) have shown that electricity prices are lower when more wind energy is installed on the power grid.    Read More »

Texas Wind Energy Continues to Blow Us Away

We have a lot to celebrate this Global Wind Day (June 15). Across the nation, wind energy accounted for almost one-third of new power capacity over the past five years and the American Wind Energy Association (AWEA) estimates that wind energy has the potential to double over the next few years.

Nowhere is the growth in wind energy more evident than in Texas, the nation’s top wind producing state. Texas' wind energy generation grew by 13% in 2013 and more than 60% of all wind projects under construction in the first part of the year were in Texas.

This success has been aided by the Renewable Energy Production Tax Credit (PTC), a modest tax credit for new facilities good for ten years after the wind farm’s start date. Like those received by the oil, gas, and nuclear industries, tax incentives help ignite growth in the market. EDF has strongly advocated for this incentive over the past few years.

Unfortunately, the breaks that oil and gas have received over the last 100 years are often (conveniently) ignored by those wanting to maintain the status quo, making the PTC a point of debate among politicians. Read More »

Desalination can Help Solve our Water Woes, but not without Clean Energy

As drought continues to grip Texas and many other Western states, one of the solutions often discussed (and pursued) to overcome water scarcity is desalination. Simply put, desalination, or desal as it is most commonly called, is a process that removes salt and other minerals from salty (brackish) or seawater to produce freshwater for drinking and agriculture. This technology seems like a no-brainer option for addressing the state’s water woes, but the problem is that desalination uses a lot of electricity and the majority of Texas’ electricity comes from coal and gas power plants, which require copious amounts of water to generate that electricity. It doesn’t make much sense to use water to make water, especially when there’s an alternative in Texas’ abundant renewable energy resources.

Texas is the national leader in wind energy and has the greatest solar energy potential in the U.S., yet neither of these resources are being widely deployed for desal plants despite recent studies pointing to vast opportunities. Not only do these energy resources produce negligible carbon emissions, but they also consume little to no water, unlike fossil-fueled power plants. Furthermore, if we look at where brackish water sources are located compared to where the wind and solar energy potential is in this state, the overlap is pretty clear. This synergy should not be ignored.  Read More »

Can Texas Keep the Lights On? Clean Energy Holds the Answer.

rp_Final-Images-EDF-6524-200x300.jpgOn Tuesday, I had the pleasure of participating on a panel hosted by the Texas Tribune that centered on the future of Texas’ power grid and electric reliability. Joining me was John Fainter, president and CEO of Association of Electric Companies of Texas, Inc; Trip Doggett, president and CEO of the Electric Reliability Council of Texas; and Doyle Beneby, president and CEO of CPS Energy, San Antonio's municipal utility. The panel, entitled Keeping the Lights on in Texas, took place at and was broadcasted from St. Mary’s University in San Antonio. It's a worthwhile watch and I'm encouraged that Texas Tribune is dedicated to investigating Texas' energy issues.

For about an hour, we discussed a variety of aspects in the current and future energy landscape of the Lone Star State. In particular, I focused on the exciting shift to give people power over their electricity use, save money, and help the environment with every flip of the switch.

Demand Response: People, not New Power Plants, are Driving the Clean Energy Future

By: Cheryl Roberto, Associate Vice President, Clean Energy

Clean energy resources, like wind, solar, and energy efficiency, have certain key advantages over traditional, fossil fuel-based resources: they don’t require expensive, polluting fuels or large capital investment, consume little to no water, generate negligible carbon emissions, and are easily scalable. To take full advantage of low-carbon, renewable energy sources, we need a power grid with enough flexibility to harness clean energy when it is available and abundant. That’s where demand response, a people-driven solution, comes in.

On a hot summer day, for example, electricity use rapidly increases as people turn on air conditioners to avoid the heat of the late afternoon. A decade ago, the grid operator’s only option is to turn on another fossil fuel power plant to meet the increased need for electricity. But, at any given time, there are thousands of light switches left on, idle water heaters, cycling swimming pool pumps, and forgotten thermostats that people could temporarily turn off or down, if only they were offered the right incentive. If asked, people can adjust their power usage in exchange for a financial reward. We call this “demand response,” and it is increasingly helping to balance the flow of electricity with our energy needs at a given moment.

Demand response diverts money that would generally go to a fossil fuel power plant to homeowners and businesses instead. In this scenario, a utility or demand response provider sends a message for participants to reduce electricity use at key times in exchange for a credit or rebate on their utility bill, in addition to the cost savings they will earn through conservation. Of course, participants always have the option to opt-out with the tap of a button on their smart phone or thermostat. Read More »

Fossil Fuel Industry's Tired Battle Against Clean Energy is Also a Losing One

Source: Alternative Energies

Source: Alternative Energies

The assault on successful renewable energy legislation continues, long after the facts have proven that state renewable policies deliver clean, affordable, and reliable energy solutions that the majority of Americans support. Apparently, the fossil fuel industry and its so-called “free market” allies didn’t get the memo.

There’s a great line in the opening scene of Ridley Scott’s 2000 blockbuster Gladiator where a soldier says to his general, as they are about to slaughter an overmatched foe, “People should know when they’re conquered.” The general replies, “Would you? Would I?”

So I can’t really blame the fossil fuel industry for fighting old battles in an effort to undo approaches that have increased investment in renewable energy in states around the country, created thousands of jobs, and continue to lower energy costs with each passing day. Read More »

Secretary Moniz Deems Austin’s Pecan Street ‘Very Impressive’

Marita with Moniz

EDF's Marita Mirzatuny with Secretary Moniz at Pecan Street's Pike Powers Labratory

Earlier this month, I had the privilege of presenting a short summary of EDF’s Smart Power Initiative to Dr. Ernest Moniz, the U.S. Secretary of Energy. As a group of over 30 people piled into the Pike Powers Laboratory (including the lab’s namesake), the Secretary made his way in, beelined for some coffee, and sat down to hear all about Austin’s innovative and collaborative energy “ecosystem.”

Present was the Mayor of Austin, Lee Leffingwell, various cleantech entrepreneurs sponsored by the Austin Technology Incubator (ATI), representatives from the State Energy Conservation Office (SECO), and the Governor’s office, among others.

Everyone had the opportunity to speak to the Secretary in a roundtable format about the work their particular company or group is doing to solve energy problems, and as EDF’s representative, I reported on our Smart Power work in Texas. Read More »

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

MaritaHeadshotAs 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.
