PDAs, Cellphones, Wireless A major deal just went down in the United States, which seriously shakes up the mobile industry on the other side of the pond: AT&T has announced it plans to buy T-Mobile USA from Deutsche Telekom.

That's one of the way photovoltaic power et al could be ready : reducing the demand ;)

However, your specific ideas raise interesting questions... I agree that electric heaters are a bad idea, but what can we use instead ? Solar heating is great, but in practice it has this big problem that it produces much less heat in winter and that heat cannot be stored for long periods, making it only suitable for "faucet" warm water. Geothermy is also nice, but does not work very well on the individual housing scale and AFAIK also requires specific natural conditions to work efficiently. Then we have the combustion way... After years of evolution, gaz heating has reached a very nice state, where it's both very efficient and quite clean in terms of pollution, but the available sources of gaz won't last forever and whether we manage to produce enough methane after that remains to be seen. Wood is quite interesting, but requires a big tree-planting policy to work : will we have enough space and political power to enforce that ?
