INSTITUTIONAL ENVIRONMENT

For information on the institutional environment of the Australian Bureau of Statistics (ABS), including the legislative obligations of the ABS, financing and governance arrangements, and mechanisms for scrutiny of ABS operations, please see ABS Institutional Environment.


RELEVANCE

The most recent Energy Use and Conservation (EUC) Survey was conducted in March 2011 and provides household information on:

• dwelling characteristics
• insulation in dwellings
• sources of energy used inside and outside the dwelling
• heating and cooling in households
• electrical appliances in households.

The survey was conducted throughout Australia as a supplement to the ABS monthly Labour Force Survey (LFS).

The survey covers households in urban, rural, remote and very remote areas across all states and territories of Australia, excluding households in Indigenous Communities.


TIMELINESS

The EUC Survey is collected triennially each March as a supplement to the ABS monthly LFS. Surveys on this topic have been conducted since 1994. Data from the survey is released approximately seven months after the completion of enumeration (i.e. during October).


ACCURACY

The sample size for the March 2011 LFS was approximately 33,000 dwellings. Only half of these dwellings were included in the sample and there were 12,841 fully responding households. Taking into account sample loss, the response rate was 93%.

Estimates in this publication are subject to sampling and non-sampling errors. Sampling error is the error associated with taking a sample of dwellings rather than going to all dwellings in Australia. In this publication the sampling error is measured by the relative standard error (RSE), the standard error expressed as a percentage of the estimate. Non-sampling errors can occur in any data collection, whether based on a sample or a full count such as a census. Sources of non-sampling error include non-response, errors in reporting by respondents or recording answers by interviewers, and errors in coding or processing of data. Every effort is made to reduce the non–sampling error by careful design and testing of questions, training interviewers, follow-up of respondents and extensive editing and quality control procedures at all stages of data processing.


COHERENCE

The previous Energy Use and Conservation Survey was conducted in March 2008. Data from both the 2011 and 2008 Energy Use and Conservation Surveys are released under the title Environmental Issues: Energy Use and Conservation (cat. no. 4602.0.55.001). Prior to 2008, the annual publication Environmental Issues: People's Views and Practices (cat. no. 4602.0) focussed on one of three rotating topics each year: Energy Use and Conservation; Waste Management and Transport Use; and Water Use and Conservation.

While the ABS seeks to maximise consistency and comparability over time by minimising changes to the survey, sound survey practice requires ongoing development to maintain the relevance of the data. For 2011, a number of data items and categories have been changed, removed and added to capture current trends and practices in household energy use and conservation. These changes are outlined in the Explanatory notes (see paragraphs 11-17).


INTERPRETABILITY

This publication contains tables with annotated data and a summary of the main findings to assist with the interpretation of the results of the Survey. Detailed Explanatory notes, a Technical note on Data Quality and a Glossary are also included providing information on the terminology, classifications and other technical aspects associated with these statistics.


ACCESSIBILITY

This publication is available electronically, Environmental Issues: Energy Use and Conservation (cat. no. 4602.0.55.001), released via the ABS website. Tables and associated RSE tables are available in spreadsheet format. Additional tables and associated RSE tables are expected to be appended to this product in November 2011.

Data is available at state/territory level and state/territory by capital city/balance of state level. Additional data may be available on request. Note that detailed data can be subject to high relative standard errors, and in some cases, may result in data being confidentialised.
