A Guide for Local Government Executives on Energy Efficiency and Sustainability

Download the publication.

This report describes an important trend in local government — an increased focus on energy efficiency and sustainability.

While the federal government receives much attention for its environmental initiatives, much activity is now taking place at the state and local levels to improve energy efficiency and sustainability. The report sets forth six strategies that local government decision makers and administrators can use to develop new sustainability programs or refine existing programs.

The strategies presented in the report by Francis and Feiock are based on a nationwide survey that the authors conducted of medium-sized cities (with populations between 20,000 and 50,000) about their energy efficiency, sustainability, and climate protection efforts. These medium-sized cities account for most of the urban population and energy conservation in the United States.

Considerable money and attention has been directed toward local energy and sustainability issues in the last few years. The road ahead, however, will be challenging as local governments face tighter budgets and declining resources. Little practical information has been developed to guide local government officials and public managers in determining how best to approach local sustainability and climate protection programs. While energy efficiency and conservation promise long-term savings, nearly 40 percent of the cities surveyed report that limited financial resources will present a significant challenge for undertaking new energy efficiency and sustainability initiatives. The goal of this report is to serve as a useful guide to local government officials as they face such challenges.

Most Plastic Products Release Estrogenic Chemicals: A Potential Health Problem That Can Be Solved

Yang CZ, Yaniger SI, Jordan VC, Klein DJ, Bittner GD 2011. “Most Plastic Products Release Estrogenic Chemicals: A Potential Health Problem That Can Be Solved”. Environmental Health Perspectives 119, 989-996. doi:10.1289/ehp.1003220

Abstract

Background: Chemicals having estrogenic activity (EA) reportedly cause many adverse health effects, especially at low (picomolar to nanomolar) doses in fetal and juvenile mammals.

Objectives: We sought to determine whether commercially available plastic resins and products, including baby bottles and other products advertised as bisphenol A (BPA) free, release chemicals having EA.

Methods: We used a roboticized MCF-7 cell proliferation assay, which is very sensitive, accurate, and repeatable, to quantify the EA of chemicals leached into saline or ethanol extracts of many types of commercially available plastic materials, some exposed to common-use stresses (microwaving, ultraviolet radiation, and/or autoclaving).

Results: Almost all commercially available plastic products we sampled—independent of the type of resin, product, or retail source—leached chemicals having reliably detectable EA, including those advertised as BPA free. In some cases, BPA-free products released chemicals having more EA than did BPA-containing products.

Conclusions: Many plastic products are mischaracterized as being EA free if extracted with only one solvent and not exposed to common-use stresses. However, we can identify existing compounds, or have developed, monomers, additives, or processing agents that have no detectable EA and have similar costs. Hence, our data suggest that EA-free plastic products exposed to common-use stresses and extracted by saline and ethanol solvents could be cost-effectively made on a commercial scale and thereby eliminate a potential health risk posed by most currently available plastic products that leach chemicals having EA into food products.

EPA Announces Top Contenders in Energy Star National Building Competition

Today, the U.S. Environmental Protection Agency’s (EPA) Energy Star program announced the top contenders at the midpoint of the 2011 National Building Competition: Battle of the Buildings. The list of top contenders identifies the leaders with the greatest percent reduction of energy use in each of the twelve building categories in the competition. EPA also provided an update on the progress of all participants as they continue to go head-to-head to save energy, reduce costs and protect Americans’ health and their environment.

“Competitors in the second year of the Energy Star Battle of the Buildings are already achieving energy-savings that really pack a punch,” said EPA Assistant Administrator for Air and Radiation, Gina McCarthy. “The stories behind these energy-savings speak to the dedication of American businesses and organizations to protecting the environment and public health, and to economic common sense.”

In the first six months of the competition alone, teams representing 245 buildings around the country have saved more than $3.7 million on utility bills and reduced greenhouse gas emissions equal to the electricity used by 2,300 homes annually. Competitors measure and track their building’s monthly energy consumption using EPA’s Energy Star online energy tracking tool, Portfolio Manager. The building with the largest percentage reduction in energy use, adjusted for weather and the size of the building, will be recognized as the winner in November.

The top contenders in each building category/percent energy reduction at the midpoint of the competition:
University of Central Florida Garage C (Other): Orlando, Fla.                                31%
Scientific Instruments (Office): West Palm Beach, Fla.                                       30%
Jackson Creek Middle School (K-12 school): Bloomington, Ind.                           26%
USE Credit Union (Bank): San Diego, Calif.                                                       20%
North Suburban Medical Office Building (Medical Office): Thornton, Colo.             18%
Office Depot (Retail Store): Plano, Texas                                                          17%
Hammond U.S. Courthouse (Courthouse): Hammond, Ind.                                  14%
First Unitarian Society of Minneapolis (House of Worship): Minneapolis, Minn.     14%
St Mark’s Medical Center (Hospital): La Grange, Texas                                      10%
Norandex (Warehouse): Rochester, N.Y.                                                           8%
Kenan Residence Hall at UNC (Dorm): Chapel Hill, N.C.                                     3%
The Colonnade Hotel (Hotel): Boston, Mass.                                                      2%

Competitors from 26 different types of commercial buildings across 33 states and the District of Columbia are utilizing social media applications, including a live Twitter feed and a Facebook forum to exchange ideas and strategies. Consumers can also go online to view details on the competitors in their region and find information about saving energy where they work, play, and learn.

Energy Star was started by EPA in 1992 as a market-based partnership to reduce greenhouse gas emissions through energy efficiency. Today, the Energy Star label can be found on more than 60 different kinds of products as well as new homes and commercial and industrial buildings that meet strict energy-efficiency specifications set by EPA. Last year alone, Americans, with the help of Energy Star, saved about $18 billion on their energy bills while preventing greenhouse gas emissions equivalent to the annual emissions of 33 million vehicles.

Water Wednesday: Smarter home irrigation technologies

Read the full post at SmartPlanet.

Contributor’s Note: This is an ongoing column in water sustainability, consumption and management issues. The rationale is simple: water is a more urgent priority for corporate social responsibility programs and becoming more so every day.

My husband and I are perfectly sympatico when it comes to the perennials and annuals we cultivate on our near-acre of New Jersey property for nine months out of the year. He picks them and plants them, I make sure they stay alive. Most of the time.

We actually only water new shrubs or plants that haven’t established and stop short of sprinkling the lawn except on very rare occasions. As you might imagine, the latter isn’t as green as it used to be, given all the hot, dry weather that wormed its way into the Northeast during July. Truth be told, though, we lose at least some plants every summer to the opposite problem: over watering.

Naturally, I read with interest some information I received in the past week from two companies seeking to provide smarter home irrigation technologies. These companies, Cyber-Rain and ET Water, have both recently released cloud services that provide guidance about when you should water — and how much.

Study finds algae growth, harvesting are root of energy ROI

Read the full story in Biodiesel Magazine.

A study recently published by researchers at the University of Texas, Austin asserts that the crux of algae’s case as an economically feasible oil feedstock and energy source rests not in its processing but in the ability to affordably grow and harvest it. The study, titled “Energy Return on Energy Investment for Algal Biocrude: Results for a Research Production Facility,” was funded by algae process technology developer OpenAlgae LLC and published in the scientific journal BioEnergy Research.

Not just Creating Little Treehuggers: Environmental Education as a Learning System

Read the full post at Sustainablog.

What’s going on in Washington these days? Duh, debt ceiling negotiations, right? Fortunately, that’s not all… there is still legislation in the works that addresses other issues beyond government spending. One bill that’s back: the No Child Left Inside Act, which would provide a funding mechanism for state environmental education initiatives.

Of course, this isn’t the first time that members of Congress (from both parties) have tried to get this law passed… its history goes back to 2007. The argument surrounding it has generally focused on a perceived ideological agenda by supporters: essentially, we treehugging types want to brainwash the young into thinking as we do.

I could try to fire back directly against this argument, but I doubt I’d change any minds of people already wedded to it. Rather, I’d like to point out some of the educational benefits I see coming from studying the natural world and efforts to protect it. Could it create kids more concerned about our use of natural resources? Sure… but I think environmental education offers some real benefits to students that have nothing to do with treehugging… and much to do with how kids learn best.

Toxics: The Long Term, Low Dose Question

Read the full post at Sustainablog.

Each year, the USDA generates an extensive set of data which demonstrates that modern American consumers face no real threat from toxic pesticide residues on their food.  This is particularly true in terms of “acute toxicity,” or short-term poisoning.  Someone would have to eat thousands to millions times their own body weight to kill themselves with produce.

To many people, that still leaves a troubling question:  “what about long term exposure to low doses of toxic chemicals and combinations of those chemicals?” This question is more difficult to answer.
