The latest 43 billion dollar Australian announcement, for a broadband network, is a good example of economic growth that can build a more sustainable economy. Communications are inherently more climate friendly than many other businesses. In Australia, the CSIRO shows every dollar spent on communications produces a third of the greenhouse gas than an average dollar across the whole economy.
This is part of a clean future. It is much easier to supply clean power for economic activities that pollute less.
And there's a big future in clean business. Currently, renewable technologies drive 170,000 jobs in the German economy. By 2020 clean tech, say analysts, may be an industry rivalling or exceeding the information technology sector.
This then is the next industrial revolution - growth in clean technology and, significantly more growth in new and emerging low carbon sectors of the economy.
