| Summary/Abstract |
When analysing price, performance and efficiency data for 15 consumer electronic and information and communication technology products, we found that in general price did not relate to the efficiency of the product. Prices of electronic products with comparable performance decreased over time. For products where the data allowed fitting the relationship, we found an exponential decrease in price with an average time constant of ?0.30 [1/year], meaning that every year the product became 26% cheaper on average.
The results imply that the classical approach of setting minimum efficiency performance standards (MEPS) by means of life cycle cost calculations cannot be applied to electronic products. Therefore, an alternative approach based on the improvement of efficiency over time and the variation in efficiency of products on the market, is presented. The concept of a policy action window can provide guidance for the decision on whether setting MEPS for a certain product is appropriate. If the (formal) procedure for setting MEPS takes longer than the policy action window, this means that the efficiency improvement will also be achieved without setting MEPS. We found short, i.e. less than three years, policy action windows for graphic cards, network attached storage products, network switches and televisions.

| Summary/Abstract |
Energy efficiency levels for the Standards and Labeling (S&L) program in India for frost free (FF) refrigerators are compared with similar programs in China, United States of America (USA), and European Union (EU). A normalization method developed by International Energy Agency (IEA) is adopted with India as a benchmark for comparison. It is observed that the energy consumption level corresponding to minimum energy performance standard (MEPS) is very high in India. India also lags behind other countries on the consumption level corresponding to highest efficiency rating. Also, the range of consumption levels corresponding to a label is wide which dilutes the efficacy of label. India has aggressively proposed to tighten the ratings for FF refrigerators in 2014 by 36% across all the bands. This measure will make its highest efficiency rating comparable to other countries. However, due to the wide gap in the consumption levels across the ratings, the revised MEPS will still lag behind other countries. One possible outcome of high MEPS is that as the ratings are tightened, the market may move to lower star rated models significantly undermining the tightening effect.
