Zee News recently reported that the Mizoram government, in collaboration with the Ministry of Non-Conventional Energy Sources, has chalked out a comprehensive one-year vision plan to provide electricity to all un-electrified villages, including households, through renewable energy resources by 2007. Under the new energy policy, apart from giving power to the unelectrified villages through renewable sources, the government would soon also make a law to use solar water heater systems mandatory for all government buildings.

This is the kind of stuff that needs to happen at the local levels (in villages, thesils, etc) for renewable energy to penetrate further in the developing world. Solar and wind power is starting to become quite accessible, and with the oil prices expected to reach $100/barrel in the next few years, our 'sustainable development' folks should be looking hard at introducing such energy sources.
