The Electricity Trust of South Australia (ETSA) is once again illuminating their head office building at No 1 Anzac Highway; this has been a tradition for 25 years.This year the display is quite different. This year they are using LED globes and LED 'rope' lighting which they anticipate will use only 5 percent of the energy used last year.
I have looked at the display in past years and often thought about the massive amount of energy being used; this use of new technology and the resulting reduction of energy use is a good move for the environment.
