With the rapidly rising cost of electricity, the answer to this headline question is complicated, with many variables affecting the real efficiencies relating to cost versus application.Most industries in Australia and throughout the world rely on compressed air as a major source of energy to operate equipment such as pneumatic controls, air tools, pumps, valve actuators, pistons and large-scale processes. Compressed air is used because it is a clean, safe and convenient energy source, but compressed air is also an expensive energy source. In fact, approximately 10% of the electricity supplied to Australian industry is used to compress air.
