EPA, DOE Strengthen Energy Star Program – Adding New Appliances & Testing Standards

March 21st, 2010

energystar

The Energy Star Program began in 1992 during the Clinton Administration as an effort to reduce energy consumption and greenhouse gas emissions.  It is an internal standard for energy efficient consumer products.

The Energy Star Program has been a success in both the public and commercial sectors.  Consumers can feel confident in ENERGY STAR because in 2009 alone, Americans, with the help of ENERGY STAR saved enough energy to avoid greenhouse gas emissions equivalent to those from 30 million cars—all while saving nearly $17 billion on their utility bills.  In 2009, ENERGY STAR Leaders together prevented more than 220 thousand metric tons of carbon dioxide equivalent and saved more than $48 million across their commercial building portfolios. These savings are more than 4 times larger than the savings achieved in 2008 and represent the single greatest year of savings since EPA recognized the first ENERGY STAR Leaders in 2004. The complete list of ENERGY STAR leaders has grown to over 100 organizations.

The EPA and DOE have launched a two-step process to expand testing of ENERGY STAR qualified products:

  • DOE began tests this week on six of the most common product types: freezers, refrigerator-freezers, clothes washers, dishwashers, water heaters and room air conditioners. These product types account for at least 25% of a typical homeowner’s energy bill. DOE will test approximately 200 basic models at third-party, independent test laboratories over the next few months.
  • The EPA and DOE are also developing an expanded system that will require all products seeking the ENERGY STAR label to be tested in approved labs and require manufacturers to participate in an ongoing verification testing program that will ensure continued compliance.

The Energy Star Program has made advances in 2009 & 2010.  See the timeline below.

  • 2/5/09: President Obama ordered the Department of Energy to clear the logjam and issue long-delayed appliance efficiency standards. The Department subsequently met every deadline and issued six standards in 2009 that are expected to save consumers between $250 billion and $300 billion over the next 30 years.
  • 7/23/09: DOE issued a subpoena to AeroSys Inc. to obtain the necessary test data to determine whether certain air conditioners and heat pumps comply with the applicable energy conservation standards.
  • 9/24/09: DOE required AeroSys Inc., a manufacturer of air conditioners and heat pumps, to provide product samples for the Department to conduct its own testing to verify whether certain models meet the federal minimum energy efficiency standards.
  • 10/13/09: DOE announced the formation of an enforcement team within the Office of the General Counsel, which is leading the Department’s efforts to monitor compliance with ENERGY STAR criteria and enforce minimum appliance standards. This includes a program to randomly review manufacturers’ compliance with DOE certification requirements and aggressively pursue any violations.
  • 12/7/09: DOE and EPA announced they were taking steps to remove the ENERGY STAR label from 20 LG refrigerator-freezer models that multiple independent labs confirmed were consuming more energy than allowed under the ENERGY STAR criteria.
  • 12/9/09: DOE announced that it would be aggressively enforcing reporting requirements that manufacturers are required to submit to the Department certifying the energy use of residential appliance models and compliance with energy efficiency standards. DOE offered manufacturers a 30 day window to submit complete and accurate reports to the Department. During that period, DOE received energy use reports from 160 different manufacturers, covering over 600,000 residential products.
  • 1/7/10: DOE announced it had signed a Consent Decree with Haier on four of its freezer models—including two ENERGY STAR models—that were consuming more energy than reported. As part of the agreement with the Department, Haier is required to notify all affected consumers and repair any defective units, and has paid $150,000 to the U.S. Treasury.
  • 1/25/10: DOE disqualified 34 CFL models from 25 manufacturers that did not meet all of the ENERGY STAR criteria for compact fluorescent lightbulbs.
  • 1/28/10: DOE initiated enforcement actions against four showerhead manufacturers who failed to certify 116 product models as meeting the federal water conservation standards.
  • 2/4/10: DOE initiated a civil penalty enforcement action against a manufacturer of air conditioners and heat pumps for failing to certify some of its products and for certifying other products when they had not been tested in accordance with DOE’s test procedure.
  • 3/7/10: DOE initiated enforcement actions against two additional showerhead manufacturers who were suspected of selling products that do not meet the federal water conservation standards.
  • 3/11/2010: EPA notified US Inc/US Refrigeration that their partnership with ENERGY STAR was terminated based on a history of logo misuse, unresponsiveness, and pattern of failure to comply with ENERGY STAR program guidelines.

Michigan’s Bay County Gets a Clean Coal Powerplant

January 1st, 2010
Clean Coal Process

Clean Coal Process

Michigan’s Consumers Energy will build a clean coal power plant in Bay County, Michigan.  The Michigan Department of Environmental Quality (MDEQ) approved the air permits for the 830 megawatts power plant.  

The burning of coal is the 2nd largest domestic contributor of carbon dioxide emissions in the U.S.  

Clean coal technologyis defined as — These include chemically washing minerals and impurities from the coal, gasification (see also IGCC), treating the flue gases with steam to remove sulfur dioxide, carbon capture and storage technologies to capture the carbon dioxide from the flue gas and dewatering lower rank coals (brown coals) to improve the calorific value, and thus the efficiency of the conversion into electricity.  

The addtion of this power plant will be good for the environment and good for Michigan.

Consumers Energy in return must retire as many as seven of its old coal-fired plants in the state.  The state utility has the oldest portfolio of coal-fired power plants in the United States, with some dating to the 1950s.  Russell said the retirements are part of the company’s energy initiative that envisions a reduction in emissions by as much as 91 percent for sulfur dioxide, 83 percent for nitrogen oxides and 81 percent for mercury.  Consumers Energy aims to meet its emission strategy in part through wind and solar power projects in Michigan.

Environmentalists battle Massey Energy to Protect W. Virginia’s Coal River Mountain

December 12th, 2009

coal-river-mountain

The environmental movement against Massey Energy’s project to remove Coal River Mountain’s mountaintop got a boost this week from Robert F. Kennedy Jr.  Kennedy spoke on behalf of the environmental movement to 300 environmentalists and 200 coal miners.

Mountaintop removal mining in Appalachia is a crime, and that if the American people could see it, there would be a revolution.  “We are cutting down the Appalachian Mountains, these historic landscapes where Daniel Boone and Davy Crockett roamed that are so much a part of American culture,” the environmental attorney said at a rally to stop blasting on southern West Virginia’s Coal River Mountain.

The Virginia based Massey Energy has been blasting Coal River Mountain to mine the coal within the mountain.  Massey is the 4th largest coal company in the U.S. and the largest in the Central Appalachian region. 

The environmental groups in opposition are Coal River Mountain Watch and Climate Ground Zero.    Both Organizations want Massey to stick with underground mining and allow the ridges to be turned into a 200-turbine wind farm.

There opposition is based on the destruction from mountaintop removal mining. 

U.S. Environmental Protection Agency (EPA) is forming a scientific panel to study how mountaintop removal has affected headwater streams and impacted downstream water quality.  The study, announced without fanfare in the Federal Register, will also examine whether coal mining companies are meeting their obligations to restore Appalachian streams where millions of tons of mining debris have been dumped.  Mountaintop coal removal is an environmentally destructive practice in which companies blast off the tops of mountains to get at coal seams below, then dump the debris in Appalachian valleys.  Hundreds of miles of headwaters streams have been buried in mining debris, and the proposed EPA review marks the first time that the agency will undertake a major review of mountaintop mining.

EPA Delays Decision to Approve Increase from 10% to 15% Ethanol in Gasoline

December 6th, 2009

ethanol

According to the University of Illinois Extension - Ethanol is an octane enhancer or anti-knock additive. With today’s higher compression engines, ethanol helps the engine be more efficient. It also helps the gasoline burn cleaner, which makes it a friend to the environment with less carbon monoxide and oxides of nitrogen (”nox”) emissions.

The Agency -

The EPA has postponed approval for the increase in ethanol until tests can be completed. 

The key legal issue for the environmental agency is whether the higher ethanol content, which causes engines to run hotter, could damage emission controls and increase air pollution. The Energy Department has yet to finish studies on the impact that gasoline with 15 percent ethanol, or E15, could have on cars and outdoor power equipment.

The agency is the options below:

  1. Approving E15 for all automobiles, boats and equipment.
  2. Allowing E15 only for automobiles made since 2004, which have more advanced engines and emission systems.
  3. Increasing the blend limit to 12 percent by ruling that E12 would be essentially the same as E10, the blend now in common use. The industry is split over this idea. The Renewable Fuels Association has argued for the E12 option as an interim step while the agency considers approving E15. Growth Energy counters that going to E12 doesn’t do enough to help the industry.

The Refiners –

Bill Holbrook, a spokesman for the National Petrochemical and Refiners Association, said some of his group’s members were already being sued on the basis that their 10 percent ethanol blends had damaged engines.

Refiners are saying they won’t put more ethanol into their gasoline unless Congress gives them protection from potential lawsuits from motorists or consumers who claim the ethanol hurt their engines.

Consumers -

Consumers of gasoline mixed with ethanol are concerned with engine damage.  Ethanol is hygroscopic (or it has an attraction to water) and readily mixes with water.   If an engine contains ethanol with water then engine damage can occur.  Marine users are at risk if their engines contain any water.   Also, ethanol can act as a solvent and loosen rust and debris that may be in fuel systems.  This can result in clog filters and engine problems.   Fiberglass fuel tanks made before 1991 may not be compatible to gasoline with ethanol.  The fiberglass may be removed and transported into engines leading to problems with the engine.  Airplanes are not approved for ethanol containing gasoline due to damage to the fuel system components (fuel lines, fuel pumps, seals, and fuel tanks).
