The latest round-up of energy-efficiency projects and innovations from Australia and around the world.
University buildings to chill out in Sydney
The University of Technology Sydney (UTS) will cool several of its city-campus buildings by piping in chilled air from a nearby district cooling system. District heating or cooling is rare in Australia, and UTS and the cooling provider Brookfield Energy say the new project is a first in the country.

Solar power towers for South Australia
US solar company SolarReserve has unveiled plans to build six large solar tower power plants with molten salt storage in South Australia. The power plants could account for one quarter of the state’s power needs, stabilise power prices due to nil fuel cost, and provide 24,000 jobs during construction.
Business Research and Innovation Initiative
The Australian Government is encouraging businesses to develop more innovative solutions to government policy and service delivery problems. Entrepreneurs will receive funding to create new products and innovations that meet defined government needs, while retaining their intellectual property and the right to commercialise the ideas in Australia or overseas.

Crocodile Dundee pub goes solar in remote Queensland
The outback hotel made famous in the 1986 movie ‘Crocodile Dundee’ has gone solar. The 24-panel installation is expected to produce 11,250 kWh a year, more than covering the pub’s total energy needs and saving over $3,000 on annual energy costs.

Kangaroo Island bounds towards 100% renewables
Ten local electricity supply scenarios were modelled as alternative sources of power for Kangaroo Island. ‘The most cost-effective alternative is a local supply of wind, solar photovoltaics and diesel generation, complemented by battery storage and demand management,’ said Director of the Institute for Sustainable Futures, Chris Dunstan.

Energy Insights Survey 2016: findings
Findings from the Energy Insights Survey indicate businesses showed greater understanding of the many aspects of energy management. Respondents also experienced growing confidence and increased self-reliance in their own energy-management capabilities. The primary finding is that energy management is becoming a core strategic imperative, with the focus shifting from cost-cutting to growth.
