New ‘Smart Cities’ Guide Helps Leaders Plan for a Sustainable Future

By Kate Zerrenner / Published: December 9, 2013

Kate ZerrennerOn November 18th, the Smart Cities Council released the Smart Cities Council Readiness Guide at the Smart City Expo World Congress in Barcelona, Spain. I am privileged to be a member of the Smart Cities Council Advisory Board, and in such a capacity, served as a review for the Guide.

The Smart Cities Council Readiness Guide is the first of its kind—a comprehensive, vendor-neutral handbook for city leaders and planners to help them assess their current state of technology and give them a roadmap for developing a smart city.

It was produced in collaboration with some of the world’s top smart city experts and includes technology recommendations for a city’s most important responsibilities: buildings, energy, telecommunications, transportation, water and wastewater, health and human services, public safety and payments.

My reviews were solely of the energy and water chapters, but the Guide as a whole offers a collection of guidelines, best practices and more than 50 case studies as well as 27 proven principles that will enable cities to achieve a smart city status. City planners will be able to identify the best path forward for their particular city, creating a customized plan that will work, even if development of the plan is gradual. Read More »

Energy And Water Are Running Out In Texas, But It’s Not Too Late

By Kate Zerrenner / Published: August 8, 2013

As we’ve highlighted in previous posts, water and energy regulators often make decisions in silos, despite the inherent connection between these two sectors. Texas is no exception.

Two very important and intertwined events are happening in Texas right now.

First, the state is in the midst of an energy crunch brought on by a dysfunctional electricity market, drought, population growth and extreme summer temperatures. An energy crunch signifies that the available supply of power barely exceeds the projected need (or demand) for electricity. Texas’ insufficient power supply makes the whole electricity system vulnerable to extreme weather events. An especially hot day (with thousands of air conditioning units running at full blast) could push the state over the edge and force the Electric Reliability Council of Texas (ERCOT), the institution charged with ensuring grid reliability, to issue rolling blackouts.

Second, Texas is still in the midst of a severe, multi-year drought, forcing state agencies to impose strict water restrictions throughout the state. The drought has already had a devastating impact on surface water and many communities are facing critical water shortages.

Although Texas has always had to deal with extreme weather events, we can anticipate even more intense weather as climate change advances. The new climate ‘normal’ makes extreme heat waves, like the historic 2011 Texas summer, 20 times more likely to occur. These extreme weather events heighten the urgency of the energy-water nexus.

Where Is All Of The Water Going? A Look At Which Energy Resources Are Gulping Down Our Water

By Kate Zerrenner / Published: July 25, 2013

If you’re like so many conscientious consumers, you’ve experienced the disappointment that comes when you realize the lean turkey breast you bought has 300% of your daily value of sodium, negating the benefits of its high-protein and low-fat content.  Instantly, food choices feel more complex; you’ve learned the hard way that the pursuit of a low-fat diet is not the same as a healthy diet.

The Energy-Water Nexus shows us that our energy choices are much like our food choices: The environmental benefits of an energy diet low in carbon emissions might be diminished by increased water consumption (or waste), and the unforeseen tradeoffs between the two resources (i.e. more sodium in lieu of less fat, can hurt us in the long run).

Water Intensity

As we have mentioned before, roughly 90% of the energy we use today comes from nuclear or fossil fuel power plants, which require 190 billion gallons of water per day, or 39% of all U.S. freshwater withdrawals (water “withdrawal” indicates the water withdrawn from ground level water sources; not to be confused with “consumption,” which indicates the amount of water lost to evaporation.)

America’s Aging Energy Infrastructure Needs An Overhaul

By Jim Marston / Published: July 19, 2013

No one likes being told “I told you so.”  But since DOE released its report last week, I’ve been tempted.

The report warns that the existing American energy infrastructure is highly vulnerable to climate change.  That increasing temperatures will stress the U.S. water system and enhance the likelihood of drought. That because conventional power plants require huge volumes of water to operate, lower water availability will mean less reliable power.  And that the changing climate will prompt more extreme and frequent storms, increasing energy demand due to extreme temperature changes and threatening our aging and already stressed electric grid with potential blackouts.

In essence, the affirms the many the calls-to-action that EDF and many other groups have been leading for years and the lessons we learned from Superstorm Sandy made painfully real and salient:  Our existing energy technologies and policies were designed for a 20th century climate.  To weather the extremes of a 21st century climate, we need to a 21st century energy system – one  that promotes energy efficiency, enables widespread adoption of homegrown, renewable sources of power and allows people to control their own energy use and reduce their electricity costs.

I have been very encouraged by President Obama’s recent movement on climate change, and the DOE report provides research backing the urgency of his Climate Action Plan.  Hopefully, this recent movement will translate into real national momentum, as our national approach to energy truly needs an overhaul.

It’s Time Our Policies Reflect The Fact That Energy And Water Are Fundamentally Intertwined

By Kate Zerrenner / Published: July 11, 2013

When I tell people that the best way to conserve energy is to conserve water, I am often faced with a confused response.  I’m not surprised really.  Energy and water policies are rarely discussed in the same forum.  For a long time, we’ve overlooked the inextricable relationship between water and energy use.  Coal, nuclear and natural gas plants use enormous amounts of water for cooling purposes.  In 2005, 41% of all freshwater withdrawals in the nation was used in the thermoelectric power industry for cooling.

Connection between energy and water

The longstanding division between energy and water considerations is particularly evident in the case of energy and water management.  These resources are fundamentally intertwined: Energy is used to secure, deliver, treat and distribute water, while water is used (and often degraded) to develop, process and deliver energy.  Despite the inherent connection between the two sectors, energy and water planners routinely make decisions that impact one another without adequately understanding the scientific or policy complexities of the other sector.  This miscommunication often hides joint opportunities for conservation to the detriment of budgets, efficiency, the environment and public health, and inhibits both sectors from fully accounting for the financial, environmental or social effects they have on each other.

This lack of collaboration between energy and water planners is especially dire considering Texas is in midst of an energy shortage that is exacerbated by the multi-year drought.  Without adequate planning, we could someday have to choose between keeping our lights on and turning on the faucet.

Environmental Accomplishments And Missed Opportunities From The 83rd Texas Legislative Session

By EDF Blogs / Published: May 31, 2013

This blog post is co-authored by Marita Mirzatuny and Kate Zerrenner.

In addition to passing tax cuts and making pecan pie the official state pie of Texas, the 83rd Legislature heard numerous energy-related bills.  As a solution to our Texas Energy Crunch efforts, EDF supported 13 bills that would have provided relief to Texas’ resource adequacy problems; in other words, the issues Texas faces as a result of increasing energy demand, scorching temperatures and a record drought.  Among those bills (which we review on page 13 of our ‘State of the Texas Energy Crunch’ report) are a few, highlighted below, that made some – albeit not enough – progress.

Energy Legislation

A big success this session was the passage of Senate Bill (SB) 385 by Chairman John Carona.  SB 385, or the Property Assessed Clean Energy (PACE) bill, clears some of the hurdles that prohibit commercial and industrial properties from taking advantage of new financing for energy improvements.  PACE allows property owners to pay for water and energy efficiency upgrades or renewable energy improvements with loans, which are then repaid through an annual charge on their property tax bill.  For more on this legislation, please see our recent blog post covering PACE in Texas.

Chairman Carona’s demand response bill, SB 1351, passed and was referred to State Affairs in the House.  Demand response (DR) initiatives allow customers to voluntarily reduce peak electricity use and receive a payment for doing so in response to a signal from their utilities.  Additionally, Chairman Rafael Anchía introduced the companion bill, House Bill (HB) 2194.  HB 2194 allows for customer, or demand-side resources (DSR), from “residential, commercial, and industrial customers to participate in all energy markets” and specifies that DSR “must be designed and implemented in a manner to increase market efficiency, competition, and customer benefits.” This bill clears the way for demand response, renewable energy, and energy efficiency to become important players in the market.

SB 1280, by Senator Kirk Watson, passed out of the Business and Commerce Committee with a seven to two vote.  This bill, regarding Texas’ reserve margin for the electric grid, requires that power regions (such as the Electric Reliability Council of Texas, or ERCOT) estimate the available generation at any given time, the expected peak demand (demand at the hottest part of the day when the most energy is being used) and the amount of reserve energy needed to ensure a reliable electricity supply.  SB 1280 also directs the use of voluntary load participation programs (think demand response) with at least 20 percent of peak energy demand coming from each of the residential, commercial and industrial sectors.

Senator José Rodríguez’s net metering bill, SB 1239, successfully passed out of the Business and Commerce committee.  Texas is one of only seven states where customers are not guaranteed fair compensation for the electricity they provide to the grid.  SB 1239 clarifies that all retail electric providers, municipal utilities and cooperatives must buy back extra electricity from residential customers along with churches and schools at a reasonable, market-based value.  For example, Los Angeles implemented the largest solar buyback program in the nation earlier this year, paying customers 17 cents a kilowatt hour for excess energy produced.

In the House, HB 303 by Representative Eddie Rodriguez called for a new renewable energy goal – to supply 35 percent of energy demand with clean energy by 2020, with at least two percent coming from solar.  This marks an important precedent for the clean energy standards introduced in state legislatures around the country.  Additionally, Representative Rafael Anchía authored HB 2196, a bill that addresses payments to customers for renewable energy and other demand-side contributions to the electric grid.

While it’s great that some of the bills gained some traction, only SB 385 made its way to the Governor’s desk.  With a hotter than average summer approaching, possibly worse than 2011, electric reliability is not a guarantee and these bills would have provided solutions to help address our energy issues.  Already Texas is receiving national attention for our impeding energy shortages.

Water Legislation

At the last minute, the House and Senate, after much back door negotiating and out front wrangling, approved a plan to fund the State Water Plan.  HB 4, by Chairman Allan Ritter, set up two funding accounts to pay for water projects.  These accounts must be approved by voters, because the bills would amend Texas’ Constitution to allow the plan to be initially funded with a portion of the Rainy Day Fund.
