摘要

From the work that has been undertaken so far it is possible to offer some 'rule-of-thumb' values that may be helpful to readers in assessing their current position and deciding how to proceed.rnSimple first order savings work out to be c. 2/3 of the energy, based on an average of the power consumption data figures. The next generation of LED signals will use less power.rnAverage installations put over 2 tonnes of carbon dioxide into the atmosphere pa. Based on an nominal energy cost of £0.10 /kW.hr and the most recent grid energy conversion factor, each tonne costs the user slightly over £185 pa.
