  • 5. Foreword The 007 Lowy Institute Poll found that tackling climate change is as important to Australians as improving standards in education - and more so than improving the delivery of health care, ensuring economic growth and fighting international terrorism. This Report is a first attempt at a nationwide quantification of the carbon savings and financial benefits resulting from using telecommunications networks to conserve energy and increase clean energy use at home, in the workplace and in ways we connect people, enterprises and communities. The analysis presented in this report finds that the telecommunications sector is uniquely placed to provide important services that can yield nationally significant reductions in greenhouse gas emissions. Indeed a key finding is that many of the telecommunication solutions for living and working in a future carbon-constrained world can actually lead to cost savings for business and the consumer. There is scant information in the public domain that quantifies the opportunities presented by telecommunications to reduce greenhouse gas emissions. This report does. This report is not the last word on telecommunications and carbon emissions, but one of the first. We welcome a robust public dialogue around the ideas presented in the report – including critiques by national and international specialists who may provide more detailed insights and more refined ideas. Climate Risk, the authors of the report, and Telstra are committed to raising the level of public discourse and to capture and share learning that can result. This dialogue will, we hope, lead to a more comprehensive understanding of how we can work together to achieve the benefits of a high bandwidth, low carbon society. Time is of the essence as we find innovative solutions to reducing carbon emissions. We are delighted to offer this study into the marketplace of ideas and we invite you to share your reactions, insights and ideas with us and with each other through forums, the media and private discussions.

The company, ‘Bye Bye Standby’, states that the device can save large amounts of greenhouse gases through lower energy consumption, reduce electricity bills and decrease the risk of home fires (BBSB 007). 5 Calculation is based on .5GWh of standby energy at a delivered price of $00 per MWh (at the lower end of non-industrial delivered electricity prices in Australia), which gives a total value of $.5 billion 5 Towards a High-Bandwidth, Low-Carbon Future Climate Risk

The ability to have the necessary information and control to intercept standby energy wastage requires devices that are both networked and controllable or power supply switches that are networked and controllable. Such devices and switches already exist, however the large scale uptake requires the ability to retro-fit such switching at low cost.

The system allows the freight forwarder to enter information on to a web-based platform which assigns orders to individual vehicles. The information is sent via SMS to the vehicle’s in-cab screen, allowing the driver to accept or reject the assignment based on timing or congestion issues. The end result is that there are less unladen vehicle trips, saving considerable time and money for both the forwarder and carrier. Furthermore, all of the information can be stored for future analysis of route planning (Software AG 007). 37 Towards a High-Bandwidth, Low-Carbon Future Climate Risk

CuRRuMBin ECO-ViLLAGE, GOLD COAST EcoVision Solutions, a Gold Coast based technology development company, uses an integrated control and management system which will facilitate cooperative management of resources in the energy and water supply chain. As a component of the cooperative framework, EcoVision has produced a home touchscreen interface which provides consumers with real time feedback of electricity, potable water, recycled water and gas usage. Greenhouse gases relating to resource consumption are displayed in graphical form as well as photovoltaic solar power or other forms of renewable energy generation. Energy use can be monitored at circuit level (eg lighting separate from general power) or at discrete appliance level. In conjunction with various in home sensors and timers, an in home EcoVision controller provides automation features to reduce energy consumption and phantom loads as well as shed loads in times of network constraint. All of the data gathered by EcoVision is sent to a central server (usually via the community network) for use by the Body Corporate, enabling comparison of performance in different households and benchmarks to be set. The important aspect of EcoVision is its architecture which facilitates aggregation of end use data far beyond the local community level. EcoVision enables occupants to offer demand side capacity back to the utility via the web at times of network constraint. This would typically include switching of major loads such as air conditioners, pool pumps and refrigerators which can contribute unnecessarily to coincident peak demand. As result distribution utilities can derive significant benefits via reduced outages and extended asset life.
