Test & Measurement of options for tackling climate change


• Engagement worldwide: Working closely with non-member countries, especially major producers and consumers, to find solutions to shared energy and environmental concerns.

• Measurements on distorted waveform including both DC and AC components and simultaneous measurement


• Evaluation of equipment against international standards


• Evaluation of uninterruptible power supplies (UPS)


The IEA and Selina The International Energy Agency (IEA) (www.iea.org) is an autonomous organisation which works to ensure reliable, affordable and clean energy for its 28 member countries and beyond. Founded in response to the 1973/4 oil crisis, the IEA’s initial role was to help countries co-ordinate a collective response to major disruptions in oil supply through the release of emergency oil stocks to the markets.


While this continues to be a key aspect


of its work, the IEA has evolved and expanded. It is at the heart of global dialogue on energy, providing authoritative and unbiased research, statistics, analysis and recommendations. Today, the IEA’s four


main areas of focus are: • Energy security: Promoting diversity, efficiency and flexibility within all energy sectors • Economic development: Ensuring the stable supply of energy to IEA member countries and promoting free markets to foster economic growth and eliminate energy poverty


• Environmental awareness: Enhancing international knowledge

Selina (www.selina-project.eu) stands for “Standby and Off-Mode Energy Losses In New Appliances”, and the main objective of the Selina project – which has now been completed - was the market characterisation of the standby and off- mode electricity consumption of new appliances in the market. This information has been collected by measurements in shops, and by gathering manufacturers’ data, in each low power mode of operation.


A key goal of the project was to identify effective market transformation


policies targeted at all the key stakeholders involved in the manufacture, sales and operation of appliances with standby and off-mode losses. The project was also intended to identify policy recommendations to the EU with the strategic objective of a market transformation in the following areas: • Increase the share of energy-efficient appliances in the market and in households


• Remove inefficient equipment from the market


• Help in the design of future new policies that enforce limitations on standby and off-mode equipment consumption


• Improve the awareness of retailers in equipment specification


• Influence consumer behaviour in the selection and operation of equipment.


Conclusion


Ensuring compliance with new standards governing energy efficiency and conservation requires accurate measurement, and the latest generation of digital power meters will help the industry to develop products that comply with them. In doing so, they will not only help manufacturers to achieve energy efficiency but will also benefit the consumers, the economy and - last but not least - the environment.
