- 5. What is an indicator? Anindicator is a defined metric used to monitor changes. Indicators can be absolute (e.g. total populations) or relative (e.g. GDP/per capita) • Population : 54 million (2014 estimate) • GDP (PPP): 725,004 billion (2015) • GDP/per capita: $13, 215 5
- 6. Why EE Indicatorsare important? 6 IEA, World Energy Outlook Special Report (Climate and Energy) 2015 EE is a growing policy priority for many countries and hence it is important to develop and maintain well founded indicators to better inform policy making. Information gained from these indicators will help policy makers to set EE targets and track progress towards these targets.
- 7. What are EEIndicators? 7 EE Indicators are an important tool for analysing the interactions among economic and human activities, energy use and CO2 emissions.
- 8. Why is theindustrial sector important? • Principle One: Do not collect statistics for the sake of collecting statistics; collect only what is necessary. • Principle Two: Identify which data already exist before embarking on a costly collection programme. 8

- 10. Barriers to EffectiveIndicators • Data Issues – There is not a single “true” indicator of energy intensity for an industry. – Global studies on industries while confidential are often limited to the main producers in industrialised countries and hence created a bias in favour of the more efficient plants, which can overestimate the industry’s average energy efficiency. – An accurate analysis of energy efficiency using physical indicators requires good quality disaggregated energy and physical production data. 10
- 11. Barriers to EffectiveIndicators • Methodological Issues: Energy use in industrial subsectors is complex. Even when necessary data are available it is often not straight forward to calculate consistent and comparable indicators that are useful for policy analysis. – Aggregation Levels: Determines the extent to which structural differences affect the results observed. – Boundaries: For a consistent analysis across countries, it is necessary to use common boundary definitions for each sub sector. – Allocation: The treatment of waste and auto- production of heat and electricity. 11
- 12. Recommendations • Establishment ofan adequate data framework is a first step in harmonising data collection efforts. Existing programmes such as PSEE and NCPC-SA are critical in ensuring that the outputs of energy audits conducted under these programmes can assist companies in complying with regulations. • Standardize definitions across all sectors. • Sector wide agreement on the EE indicators which are most relevant and meaningful to measure progress. 12

Editor's Notes
- #5 Detailed indicators can help identify areas for energy reduction, within a process Energy management systems can help develop, track and improve energy indicators in business.
- #7 Energy efficiency is a growing policy priority for many countries around the world. It is widely recognised as the most cost-effective and readily available means to address numerous energy-related issues, including energy security, the social and economic impacts of high energy prices and concerns about climate change. At the same time, energy efficiency increases competitiveness and promotes consumer welfare. In this context, it is important to develop and maintain well-founded indicators to better inform policy making and help decision makers formulate policies that are best suited to domestic and/or international objectives. The International Energy Agency produced a special report earlier this year on Climate and Energy and this graph illustrates the impact of different policy measures on global CO2 emissions. As one can see energy efficiency measures can be responsible for up to 49% of reductions.

- #10 Level One (Total Industry Sector): The commonly used indicator of the aggregate level is energy consumption per unit of GDP. This ratio measures how much energy is needed to produce one unit of economic output. However, it would be misleading to evaluate the performance of energy-efficiency based on this indicator as it is affected by many non-energy efficiency factors such as the structure of the industry, the quality of resources and, for some industrial sectors, weather conditions. Level Two and Level Three (Industry Sectors): The industries represented in level 2 and level 3 usually differ by country according to the data available and the relative importance of each industry. At these levels, the best indicator to assess energy efficiency is energy consumption per unit of production. However, as some industries are too heterogeneous to have one measure of production, GDP (or another monetary value such as gross output) is the second best choice. Level Four (Process Indicators): Only a limited number of countries have this information for a limited number of industries. However, even partial information at this level can help explain the trends in energy consumption.
