Local energy networks

From the Neighbourhoods site:

"The future will be shaped within a national system of local energy networks; a system where every part of our existence – our home, our roads, our workplaces, schools and hospitals – are generators of sustainable energy rather than just consumers of it.

"This isn't pie-in-the-sky thinking. It is already happening now; and being driven by local visionaries and engineers who have metamorphosed into eco-engineers, holistic scientists and sustainability designers. The more I became immersed in the construction of my own eco-house, the more I entered a world which is both humbling and exhilarating. Some 80% of new buildings in Berlin have solar powered energy generators. Holland has installed ‘hot road' energy systems under asphalt road surfaces that provide heating/cooling for local houses. (Every 1 km of road heats about 100 houses). Toronto is replacing energy guzzling, air conditioning systems in modern buildings, with a cooling system that circulates (and returns) water from Lake Ontario. Woking, in England, has installed its own local wiring system, generates 135% of its own energy needs, and will be coming off the National Grid in the next few years."
