Governments have been tracking trends in the efficiency of appliances on the market since 1993 in order to help in the evaluation of the impact of the energy labelling program. Each year a report is prepared detailing these trends. The latest report titled "Greening Whitegoods 2005" which includes data up to 2005 (NAEEEC report 2006/06) can be downloaded from the electronic library.
There are a number of other reports and papers that are available from the electronic library that may be of interest in terms of program evaluation:
For all appliances covered by the energy labelling program in Australia, the sales weighted energy consumption is decreasing. The key results by appliance type are summarised below. No data on trends in the air conditioner market is available in the report.
Market Trends: Total sales increased at 2.6% per annum over the 13 year period. Side by side (Group 5S) refrigerators sales doubled from 2003 to 2005 (to 12% share) although 2 door frost free refrigerator/freezers (top and bottom freezers) - Group 5T and 5B - still dominate the market with 63% of sales. Single door refrigerators with a short-term freezer compartment (Group 3) and two-door cyclic defrost refrigerator/freezers (Group 4) have virtually disappeared from the market. Average fresh food and freezer volumes now appear to be stable after freezer volumes increased during the 1990's. Prices (within each Group) have generally decreased slightly in real terms over the analysis period.
Energy: Energy consumption decreased at an average of 3.9% per annum from 1993 to 2005. Energy efficiency (taking account of changes in volume) increased at 4.6% per annum over the period. The average star rating under the old rating system climbed from 3.58 in 1993 to 4.39 in 2005. Under the new star rating system this increased from 1.76 in 1993 to 3.78 in 2005. The relative fall in energy from 2003 to 2005 was 23% for refrigerators, which is likely to be in response to new MEPS levels introduced on 1 January 2005. In 2003, 88% of refrigerators sold did not pass 2005 MEPS levels while in 2005 only 6% sold failed to meet 2005 MEPS.
Market Trends: Total sales grew at an average of 4.8% per annum, although the majority of this increase occurred in years 2004 and 2005 (sales before this date were fairly static). The average volume of freezers is fairly static overall. The sales of frost free vertical freezers (Group 7) is continuing to slowly increase while manual defrost vertical freezers (Group 6U) increased very sharply in 2004 and 2005 - this trend is not understood and is being investigated more closely. Chest freezer (Group 6C) sales constitute nearly 50% of the market and have been fairly steady. Prices (within each Group) decreased or were stable in real terms over the analysis period.
Energy: Energy consumption decreased at an average of 4.0% per annum from 1993 to 2005, with the most significant decline occurring in 2005, linked to the introduction of the more stringent freezer MEPS in January 2005. Energy efficiency (taking account of changes in volume) increased at 3.3% per annum over the period. The average star rating under the old rating system climbed from 4.24 in 1993 to 5.22 in 2005. Under the new star rating system this increased from 1.48 in 1993 to 3.4 in 2005.
Market Trends: Total sales increased at 2.2% per annum over the analysis period. Front loading machines are dramatically increasing their market share and constituted 30.9% of all machines sold in Australia in 2005. The market share of front loaders in Western Australia and South Australia are the highest at 39% and 37% respectively. Average capacity is increasing steadily for both front and top loading machines and is now 6.7kg and 6.4kg respectively for these types. Water consumption decreased by 2.8% per annum over the period. Prices have decreased in real terms for top and front loaders over the analysis period. Twin tubs have increased in price in recent years but the average capacity for this type is now much larger and sales share remains at about 2%, so this only has a minor overall impact.
Energy: Energy consumption showed a slight decrease until 1998, but there was a significant increase in energy in 1999 and 2000. This increase was attributed to top loading machines only. Since 2000, energy consumption has been declining although a slight increase was noted in 2005. Most of the decrease is a result of increased market share of front loaders. The average star rating under the old rating system climbed from 3.39 in 1993 to 4.28 in 2005. Under the new star rating system this increased from 1.28 in 1993 to 2.4 in 2005, noting however that both old and new star ratings decreased in the years 1999 and 2000.
Market Trends: Total sales increased at an average of about 4% per annum from 1993 to 2005, but there has only been a small increase in sales since 1995. The market share of auto-sensing dryers has increased significantly from 10% in 1993 to 44% in 2005. Average load capacity has been static since 1993. Prices for timer dryers were generally steady in real terms over the analysis period while auto-sensing dryers have decreased in real terms over the analysis period.
Energy: Energy consumption decreased at an average of 0.7% per annum from 1993 to 2005. All dryers appeared to decline slightly in efficiency in 2000 as a result of the new test method (lower initial moisture content). The average star rating under the old rating system increased only slightly from 2.40 in 1993 to 2.49 in 2005. Under the new star rating system this increased from 1.52 in 1993 to 1.59 in 2005. These increases are primarily due to an increase in market share of auto-sensing dryers.
Market Trends: Total sales are continuing to increase with a growth of 5.4% per annum from 1993 to 2005. Average capacity (place settings) has been stable since 1996 although there has been a slight decline since 2000. Water consumption decreased by over 4.0% per annum over the period. Prices were steady in real terms to 2003 but fell slightly through to 2005.
Energy: Energy consumption decreased at an average of 3.6% per annum from 1993 to 2005. The average star rating under the old rating system climbed from 4.07 in 1993 to 5.4 in 2005. Under the new star rating system this increased from 1.88 in 1993 to 2.8 in 2005.
