Luxury or Necessity?

2
by data sources, energy • Tags: , , , , , , , , ,

A study by the Pew Research Center’s Social & Demographic Trends project from April 2009 reveals that Americans are paring down the list of familiar household appliances they say they can’t live without.

No longer do substantial majorities of the public say a microwave oven, a television set or even home air conditioning is a necessity. Instead, nearly half or more now see each of these items as a luxury. Similarly, the proportion that considers a dishwasher or a clothes dryer to be essential has dropped sharply since 2006.

These recession-era reevaluations are all the more striking because the public’s luxury-versus-necessity perceptual boundaries had been moving in the other direction for the previous decade. For example, the share of adults who consider a microwave a necessity was just 32% in 1996. By 2006, it had shot up to 68%. Now it has retreated to 47%. Similarly, just 52% of the public in the latest poll say a television set is a necessity — down 12 percentage points from 2006 and the smallest share to call a TV a necessity since this question was first asked more than 35 years ago.

Plug Load

This post is part of our definitions series on “eco-lingo” and technical terms.

– – –

A plug load is basically any piece of equipment or electronics that plugs into an outlet in a building, including televisions, cell phone chargers, laptops, entertainment equipment, and blenders. Larger appliances are often considered to be a separate category, but are sometimes also categorized as plug loads.

When designing a building to meet code, or to estimate energy use, designers generally take major building systems, such as lighting and HVAC, and major appliances, such as refrigeration and wet cleaning equipment, into account. But it is much harder to estimate all the plug loads that buildings occupants will bring with them. And plug loads have been increasing over time as people accumulate gadgets and equipment. As the other loads in a building are driven down through increased equipment efficiency, optimized controls, and behavioral changes, plug loads are a sizeable percentage of the remaining load.

There have been a number of efforts to regulate the efficiency of certain plug loads – California approved television efficiency standards in 2009.

Martin Holladay, at GreenBuildingAdvisor.com, describes the importance of taking plug loads into account when calculating building energy use in a post here.

A California Plug-Load Energy Efficiency Center is being planned and will be hosted by the University of California, Irvine. My understanding is that it will be modeled after the California Lighting Technology Center and the Western Cooling Efficiency Center, both located at UC Davis.

A pdf of the PowerPoint slides from the planning workshop can be read here.

What exactly does “sustainability” mean? How about “green”, “eco” or “environmentally friendly”? The truth is that these terms are just vague enough to mean many different things to many different people. With the staggering array of “green” products, ‘lifestyles’ and concepts being promoted by marketers and environmentalists alike (as well as the necessary coining of new terms to match new ideas) our definition series aims to make sense of the rising tide of “eco-lingo” and technical terms.

A few days ago, appliance manufacturers and energy efficiency advocates announced an agreement to call for new national minimum efficiency standards to improve energy and water efficiency standards for refrigerators, freezers, clothes washers, clothes dryers, dishwashers, and room air conditioners. The coalition of major appliance manufacturers, their trade union, and the energy efficiency advocates propose that the new national minimum efficiency standards and tax credits be instituted through action by the Department of Energy and by Congress.

According to the press release, the recommended standards and tax credits would save more than 9 quads of energy over 30 years. The recommended water efficiency standards and tax credits for clothes washers and dishwashers would save about 5 trillion gallons of water over 30 years.

Below, I’ve put together a rough timeline of how the proposed standards would take effect:

  • January 2013 – dishwashers would see 14% energy savings and 23% water savings
  • January 2014 – new refrigerator and freezer energy reduced up to 30%
  • June 2014 – room air conditioners would increase in efficiency 10-15%
  • 2015 – top loading clothes washers would have 26% energy savings and 16% water saving compared to current standards
  • 2015 – front loading clothes washers would have 43% energy savings and 52% water savings compared to current standards
  • 2015 – clothes dryers will increase in efficiency 5%
  • 2018 – top loading clothes washers would have 37% energy and water saving compared to current standards

An overview of the agreement is here.

The agreement was signed by major appliance manufacturing members of the Association of Home Appliance Manufacturers (AHAM) and by major energy and water efficiency organizations, consumer groups and environmental organizations including the American Council for an Energy-Efficient Economy, Alliance for Water Efficiency, Alliance to Save Energy, Appliance Standards Awareness Project, Consumer Federation of America, National Consumer Law Center, Natural Resources Defense Council, Northwest Power and Conservation Council, and Northeast Energy Efficiency Partnerships.
