eta is the Greek symbol for efficiency, hence the name of the Awards. The purpose of the eta Awards is to reward exceptional effort in the more efficient use of energy by individuals, students, companies or other institutions.
The more electricity we use, the more electricity needs to be generated. We flick on switches without thinking that behind the supply of power to our homes and businesses is a complex chain of supply that stretches back hundreds of kilometres to power stations across the country.
The higher peak demand for electricity grows, the more new power stations are required. This requires massive capital investment and, in turn, pushes up consumer energy costs. The environment will benefit from the efficient use of energy.
For example, every kWh (Kilowatt hour) of electricity saved means a saving of 1,4 litres of water and one less kilogram of carbon dioxide generated by a power station.
