Estimation of the Electricity consumption of lifts according to different scenarios in the industrial sector Figure 6‐7. Estimation of the total Electricity consumption of lifts according to different scenarios 84
The results show that overall savings of more than 65% are possible. A reduction of 10 TWh is achieved using the Best Technologies Available and of 12 TWh when technologies that are currently being developed are used, which translates into a reduction of around 4,4 Mtons of CO 2eq and 5,2 Mtons of CO 2eq , respectively, with the current electricity production methods. Savings in the standby energy consumption are particularly noticeable even in the BAT scenario where although low power equipment is used it is always kept on even when it is not in use, as it is presently the common practice. A reduction in stand‐by power of over 80% is considered feasible with off‐the‐shelf technologies. In particular, the use of LED lighting can play a major role in this reduction. 85
