In Texas, Freshwater Use For Oil And Gas Should Be Reduced Strategically

Texas is suffering from a water deficit; one that is spurring lawmakers at the Texas Capitol to discuss unprecedented, and much needed, investments in our water infrastructure.  With roughly 98 percent of the state in drought and water use restrictions in place in 70 percent of Texas counties as of April 3, 2013, it is crucial that our legislators consider every tool available to protect Texas’ water supply.  One approach is reducing freshwater use in the oil and natural gas sector, which can help alleviate competition for scarce water resources; however, this should be deployed at strategic places and times to minimize pollution risks and ensure a sustained future water supply for Texas.

In the Texas Legislature, the House recently passed a bill which will provide $2 billion to fund water supply projects.  It might surprise you to hear that this high price tag represents less than 10 percent of the state funding that will be needed over the next 50 years to sustain water supplies for Texas’ growing population.  In light of this, it is essential that legislators enact bills that encourage responsible water management solutions. Although the oil and gas industry’s water use appears miniscule when considered on a statewide basis, even small amounts can have a big impact in the most water stricken areas. EDF created a map of the counties in Texas currently being impacted by water scarcity and that would benefit greatly if the oil and gas sector reduced its use of freshwater.

Data used to create the map revealed the following:

  • The majority of water used for Texas oil and gas development in 2011 was in 13 counties, ten of which currently have water restrictions in place.
  • For 12 counties, oil and gas water use made up at least 25 percent of overall county-wide demand in 2011.
  • In 15 counties, oil and gas water use is projected to be greater than or equal to 25 percent of the water deficit in those counties in 2020.
  • In five counties, 100 percent of the water deficit projected for 2020 can be met by cutting oil and gas water use by half.

The oil and gas industry is a prime candidate for reducing its reliance on freshwater because – unlike the agriculture and municipal sectors – using non-freshwater is technologically feasible.  Some of the most popular alternative water sources for the oil and gas industry include brackish (or salty) water, treated flowback water from hydraulic fracturing and reclaimed water from public wastewater treatment plants.  Taking advantage of these options could be a win-win-win for industry, people and the environment.

America’s Schools On The ABCs Of Energy Efficiency

As part of my role at EDF, I keep track of stories about the benefits of energy efficiency. By that, I don’t just mean data and figures, rather stories about the real, tangible and positive impacts saving energy can have on everyday people. We live in a data-driven world, especially those of us who work on energy and climate issues, but it’s the stories about people that really stay with us. In the past few months, I’ve noticed a quite a few stories from local papers around the country discussing the benefits that schools have seen from implementing customer, or demand-side, solutions – such as energy efficiency, on-site renewables, like rooftop solar, and demand response (DR) initiatives – which allow customers to voluntarily reduce their high electricity use and receive a payment for doing so in the process.

For example, a story from the Louisville, Kentucky National Public Radio station WFPL covering the nation’s first net-zero school recently caught my attention.  To be considered a true “net-zero” building is an impressive feat, because it means the facility’s net annual energy consumption, AND its carbon footprint, is zero.

The featured school, Richardsville Elementary in Warren County, has made some impressive improvements, from installing geothermal heating and cooling, bamboo gym floors, solar panels on the school rooftop and in the parking lot, efficient cooking technologies in the cafeteria to using a ton of natural lighting. As a result, the school receives zero utility bills. But the two most compelling pieces of this story are the energy costs and the educational opportunities.

Kentucky has some of the cheapest electricity prices in the country. Many states, particularly in the southern U.S., also have low electricity prices—meaning, the cost incentive is not as powerful for energy efficiency. But I would argue that, regardless of electricity prices, schools always have an incentive to save money. With schools, for every energy dollar saved, one more dollar goes to good teachers, textbooks and computers. And the non-monetary incentives are extra important when talking about children, whose developing lungs need the cleaner, indoor air and more natural lighting that come with efficiently-designed schools, as detailed in my previous post on schools.

Don’t Turn The Lights Off On Demand Response

Source- FERC: National Assessment of Demand Response Potential

If Texas Legislators want to make sure the lights stay on this summer, they have a great opportunity to do so tomorrow, April 9, 2013, while saving electric customers money.  There are two critical bills being considered at the legislature in Texas that would expand the use of demand response, a tool that allows customers to voluntarily reduce peak, or high, electricity use and receive a payment for doing so in response to a signal from their energy provider.  We need to take advantage of tools like demand response to alleviate the pressures facing the Texas electric grid, what EDF refers to as the ‘Texas Energy Crunch,’ which include a shrinking water supply, growing population and rising summer temperatures.

Demand response has been identified by numerous experts as a key component to a reliable electric grid in Texas, and Tuesday’s Senate Business & Commerce Committee hearing at 8 am represents a great opportunity for the legislature to help meet future energy needs while providing direct benefits to customers and reducing water usage.

Demand response is critical to keeping the Texas electric grid humming.  According to a comprehensive report on the Electric Reliability Council of Texas (ERCOT) reliability from the Brattle Group, “the energy-only market will not dependably support ERCOT’s current reliability target until sufficient demand response penetration is achieved.”  Demand response can be deployed in a matter of months, while it usually takes two to five years to build a natural gas power plant, even after all the permitting and financing is completed.  At the same time, demand response provides financial incentives; in the mid-Atlantic region, where demand response plays a critical role in the electric market, customers were paid a total of $330 million last year.  At the same time, according to the grid operator for the region, PJM, demand response actually lowers overall energy system costs by bringing more competitive resources into the market.  During the summer of 2012, PJM estimates this effect saved all customers around $650 million.

An Old-Timer Reflects On The Importance Of New Technology To Battle Methane Emissions, And What You Can Do About It

Anyone younger than 30 may not understand what a skipping record sounds like;  in their lives, listening to tunes has more often meant hitting a playlist on iTunes or streaming Pandora, than it has meant dusting off an old record. To us “old” folks who remember when clunky 8-track tapes were the height of portable music cool, today’s options are nothing less than astounding.

Believe it or not, I was thinking about this as I participated yesterday in a panel at the World Resource Institute in Washington, D.C. to discuss their new paper titled, “Cleaning the Air: Reducing Upstream Greenhouse Gas Emissions From U.S. Natural Gas Systems.”  Reviewing the report, and reflecting on EDF’s own work to understand and reduce methane and other air pollution, it’s clear a huge opportunity exists for technology to revolutionize air quality practices in the gas industry, just as it reengineered production and delivery of audio in the music industry. And the prospects are very bright that it will.

Champions of natural gas like to say that natural gas is a preferred fossil fuel alternative to coal and oil because it has less carbon content than either, and therefore, when burned, produces less carbon dioxide, which is the a primary cause of global warming. This is true.

But what is often not said is that natural gas is primarily made up of methane, which itself is a powerful greenhouse gas pollutant, many times more powerful than carbon dioxide, particularly when methane is first released into the atmosphere. Even small leaks at the wellhead or along the infrastructure used to process and transport the gas to our power plants, homes and businesses can undo much of the greenhouse gas benefits we think we are getting when we substitute natural gas for coal or petroleum sources.  Read More »

New York City’s Air Is Well On Its Way To Becoming Cleaner Than Ever

NYC Clean Heat is halfway to achieving its goal of reducing harmful heating oil soot pollution in New York City by 50 percent by the end of 2013.

The NYC Clean Heat program experienced tremendous growth in 2012. The Mayoral announcement in June 2012 marked the official transition from the pilot phase to full implementation of the NYC Clean Heat program, which aims to clean the air in New York City by helping buildings convert from highly-polluting No. 6 and No. 4 heating oils to the cleanest available fuels. The heating oils used in one percent of New York City buildings create more soot pollution than all the cars and trucks in the City combined – that’s why upgrading these buildings to cleaner heating fuel is the single largest step New Yorkers can take to solve local air pollution.

The goal of NYC Clean Heat is to cut heating oil soot pollution in half by the end of 2013. NYC’s Department of Health estimates that achieving this goal will result in over 120 lives saved each year and prevent hundreds of emergency room visits and hospitalizations for respiratory and cardiovascular conditions.

I’ve been a part of the NYC Clean Heat team for almost two years now, and I can tell you that I am floored by the progress we’ve made. For instance: 

  • By the end of 2012, over 1,200 boilers – well beyond the number of conversions the regulations required – have switched to natural gas or ultra-low sulfur No. 2 (some of the cleanest available fuels), and over 2,000 additional boilers in line to convert.
  • These 1,200 conversions have resulted in over 150 tons of reduction of soot pollution, or particulate matter (PM2.5), which is equivalent to removing over 800,000 light-duty passenger vehicles from the road for 1 year. That’s over 13 billion miles travelled!
  • NYC Clean Heat won the 2013 Citizen Budget Commission’s Award for Public Service Innovation.

Why is all of this important? Approximately 1,500 buildings still need to complete conversions in 2013. Also, roughly 2,000 permits for No. 6 oil are set to expire before March 2014, representing 232 tons of soot pollution. Because this week is National Public Health Week, we are more aware than ever of what reducing air pollution in New York City will mean. NOW is the time to take action. Read More »

Consumers At The Heart Of Illinois Smart Grid Revitalization Project

On April 1, Illinois’ largest utilities, ComEd and Ameren Illinois (Ameren), updated their plans to launch one of the nation’s largest electrical grid upgrades, a $3.2 billion project that will set the stage in Illinois for how utilities and customers interact in the future.  The ComEd and Ameren plans provide new detail on how they intend to replace the aging Illinois grid and begin to transform it into a digital smart grid capable of monitoring customer and environmental benefits.  EDF and Citizens Utility Board (CUB) teamed up with both utilities to create twenty new benchmarking metrics that will measure how the utilities deliver benefits to consumers and improve their performance annually. 

To elaborate, such metrics include reductions in peak energy demand, increased adoption of renewable energy, such as solar power, wide-spread implementation of smart energy devices and diminished greenhouse gas (GHG) emissions, among others.  In addition, ComEd and Ameren have elected to work with EDF and CUB to develop new and better ways to measure how smart grid technology can help reduce GHG emissions and electrical inefficiencies.  Using smart grid devices to precisely measure GHG and line loss is technically challenging, but key to unlocking the promise of smart grid technology.

When customers are empowered with the knowledge and tools to control their own energy usage, they are also empowered to save money on their utility bills.  As CUB Executive Director David Kolata points out, “A smart grid begins with smart policy. These new metrics will help bring the power grid into the 21st century more quickly and cost-effectively, ensuring that consumers see the benefits in the form of lower electric bills.”

To take full advantage of the $3.2 billion project, born out of the Illinois Energy Infrastructure Modernization Act of 2011, ComEd and Ameren must go above and beyond the business-as-usual utility metrics.  Utility metrics to date have commonly focused on general measures to gauge customer benefits, such as customer awareness survey completions and number of customer outreach events attended.  These new tracking mechanisms go further in that they will allow the utilities to track and report where customers are realizing the benefits of electric grid improvements, and the extent to which they are participating in these opportunities.  This includes measures like the number of customers who can directly access their own energy usage data and the time it takes to connect renewable energy resources, like solar power, to the electric grid.

A Silk Purse From A Sow’s Ear: Federal Cuts May Spur Environmental And Energy Savings

Holly Pearen, EDF’s Attorney for the Natural Gas Campaign, contributed to this blog post.

Source: http://bit.ly/10w6rIi

The federal government notified 36 states last week that it plans to temporarily stop monthly mineral revenue payments as a part of the mandatory sequestration budget cuts. These cuts will hit western states especially hard with an estimated $26 million cut coming to New Mexico over the next six months, $8.7 million to Utah, $8.4 in Colorado and $5.5 in California, while North Dakota and Montana will see $3.2 and $2.5 million in cuts, respectively, according to data from the U.S. Department of Interior’s Office of Natural Resources Revenue.

However, no state will be hit as hard as mineral resource and federal lands-rich Wyoming, which has been notified to prepare itself to lose $53 million in federal mineral revenue payments through July.

The money is the state’s share of royalties paid by producers who operate on federal leases in Wyoming. Not surprisingly, Wyoming officials are very unhappy with the federal plan, both its details and the way it was announced to the states via letter with little forewarning. As Wyoming Governor Matt Mead said in a statement: "As far as communications go, this method of passing along significant information that greatly impacts Wyoming gets a grade of F minus or worse. It is not acceptable."

While Governor Mead has vowed to fight the plan and is working with the Wyoming Attorney General, Wyoming’s congressional delegation and neighboring states to come up with a strategy to oppose the cuts, we would like to offer a suggestion. Perhaps Interior should make up the shortfall owed to the states by charging royalties on vented and flared natural gas? Read More »

Solar Market Needs New Investors To Continue Growth

The recent headlines for solar power have been encouraging.  According to the Solar Energy Industries Association (SEIA), the cost to install solar is declining as panel prices fell by 41% in the fourth quarter of 2012 versus the previous year.  This helped US solar installations to grow by around 75% in 2012, from 1,855 megawatts (MW) in 2011 to 3,300 MW.  (For comparison, the average coal plant in the US has a capacity of about 650 MW).  Even better, they forecast that installations will continue to climb to an estimated 9,000 MW in 2016.

Unfortunately, lack of investment capital may be a barrier to realizing this vision.  If we do not have enough funding, these projects will never be built.  Bloomberg New Energy Finance forecasts that the industry will need $3.1 billion of equity investment in 2013, compared to $1.8 billion in 2012.  Environmental Defense Fund (EDF) is committed to helping expand the roster of investors in solar projects, as investing in these projects is often not only highly profitable but also a major contribution to the sustainability of our planet.

Large investors have developed two strategies to invest in solar projects.  The traditional method is to make investments in large, utility scale projects.  More recently, residential solar developers have created funds for investors to take stakes in a large number of residential and small commercial projects.  The latter strategy has made ‘no-money down’ solar available for homeowners who do not have the upfront capital to purchase solar systems, which can cost up to $15,000 or more.

Unfortunately, these investment strategies can be quite complex and are generally attractive only for corporations and certain wealthy individuals. To understand why, we need to explore the tax incentives for solar investors.  The federal government provides tax breaks for solar investors to accelerate deals, develop a robust market that is expected to lower costs over time and allow investors to capture part of the societal benefit of avoiding development of more fossil fuel power plants.  EDF believes that this is a very good idea.

The Texas Energy Crunch Report: Looking Back And Looking Forward

We have been blogging about the ‘Texas Energy Crunch’ for over a year now, and the issue has attracted attention from the media, the Texas Legislature and even international groups.  During all of that time, the Texas Public Utilities Commission (PUC), Electric Reliability Council of Texas (ERCOT) and stakeholders have continued to try to develop new markets and programs that will help ensure the state of Texas can keep the lights on this summer and into the future.  This seems like as good a time as any to step back and take stock of how far we have come and how far we have left to go.  To that end, EDF released this report: “The State of the Energy Crunch in Texas.”

The Energy Crunch is not a fleeting issue that will go away in the near future. It’s critical that we take action now to preserve our electric grid, the engine of the Texas economy, over the long-term as we face a shrinking water supply, a growing population and rising summer temperatures.  The ongoing drought puts Texas' power plants at risk, threatening a return of the rolling blackouts caused by extreme winter conditions we experienced in 2011. State Climatologist and Governor Rick Perry appointee, John Nielsen-Gammon states, “Statistically, we are more likely to see a third year of drought.”  In recent testimony, Nielsen-Gammon reaffirmed that if the drought continued through this year, this drought is likely to be the second worst episode of drought in Texas’ history.

The solutions are out there in the form of customer, or demand-side resources, like energy saving demand response (DR) initiatives (which allow customers to voluntarily reduce peak electricity use and received a payment for doing so in response to a signal from their utilities), energy efficiency programs and increasing renewable energy sources like solar and wind power, all of which consume almost no water and can be built faster than gas and coal plants. This report provides an overview of these issues and concludes with legislative recommendations that will help meet future energy needs while providing direct benefits to customers and reducing water usage.

As economic growth continues to surge in Texas, state leadership must ensure a stable and secure supply of electrical power to businesses large and small, homeowners, hospitals and schools, among others. This challenge is critical in the face of a worsening drought, population growth and the failure by the PUC to take meaningful action after almost two years of deliberation. In the final months of the 83rd Legislative Session, lawmakers have an opportunity to directly address the Energy Crunch through several pieces of legislation that would help reduce customer energy bills, lower water consumption and increase business opportunities in Texas, while also reducing peak electric demand throughout the state.

Several of these opportunities have been identified by the PUC, but a lack of clear direction from Commissioners has left businesses hesitant to engage directly in the Texas market without a good understanding of the long-term outlook.  By providing the PUC with strong guidance on issues like demand response, innovative clean energy financing mechanisms and fair payment for locally generated electricity, the Legislature can help reduce the threat of extremely costly rolling blackouts across the state.

We cannot solve this problem with the same thinking that got us here. Technology has changed our lives and the energy industry over the past few years alone, creating new opportunities for innovation. Now the state needs to be smarter about the way energy is used, and it starts with using technology to better manage our electric grid. This includes taking advantage of market-based solutions such as demand response (DR), energy efficiency programs and the continued growth of renewable energy into a smart grid.

In our report, EDF details legislation that is currently being considered by several Texas House and Senate Committees to help meet future energy needs while providing direct benefits to customers and reducing water usage.  The list includes bills that allow all customer classes to participate in electric markets, provide innovative clean energy financing mechanisms and offer fair compensation for customers who provide power back to the electric grid by generating excess electricity from renewables or conserving energy using demand response initiatives.  The Energy Crunch hasn’t ended by a long shot.  Forecasts continue to show that we won’t have the level of reserves needed this summer to ensure reliability –particularly if the summer looks anything like 2011.  Similarly, EDF will continue to engage in the issue both on our Texas Energy Crunch website and through the discussions going on at ERCOT, the PUC and the Texas Legislature.

Stayed tuned as we continue to develop innovative, market-based environmental and economic approaches that seek to keep the lights on and benefit customers.

Industry And Environmentalists Make Progress On Fracking

This commentary was originally posted on our EDF Voices blog.

Source: danielfoster437/Flickr

Worthy public policy initiatives get announced every day of the week, and reporters mostly greet them with a shrug. But last week’s announcement of a new center designed to set standards for shale gas development in the Appalachian Basin triggered a wave of media attention.

The Washington Post called the Center for Sustainable Shale Development (CSSD), “a heartening breakthrough in the war over fracking.” And the Associated Press wrote: “Some of the nation's biggest oil and gas companies have made peace with environmentalists, agreeing to a voluntary set of tough new standards for fracking in the Northeast….”

I agree that this is a big deal, and not just because EDF played an important role in the two years of negotiation that led to the formation of this group. It’s a rare to see environmentalists and some of the nation's biggest energy companies working together to improve the safety of natural gas operations.  This coalition is a step in the right direction to better protect the quality of life for people living among the gas fields.

But, I also need to make a few points clear.

First, the standards put forth by CSSD are no substitute for strong regulation and enforcement.   Voluntary efforts by industry leaders help distinguish the best from the rest and raise the bar for all, but the only path to full protection of our air, water, and health is regulation and enforcement that apply to all.    Read More »
