Decentralised solar

Orissa in India has decided to electrify approximately an additional 2,000 villages by March 2012. But instead of coal-fired power plants, it will be using decentralized solar power.

Biomass, wind power and a variety of small-scale hydropower projects are also in the mix. Further renewable energy development in Orissa includes 118 MW of biomass plants, with 20 MW of that to be completed soon. Two wind power projects, 150 MW in size are in the works, with surveys for 22 more locations underway. Micro, mini and small-scale hydropower projects are also planned for deliver an additional 300 MW.

Well, that's good news. Maybe this is the way forward for the thousand unelectrified villages. Grid connected energy will be difficult due to land use constraints as well as costs. In case of solar thermal, water use becomes a problem. But decentralised power avoids most of these issues.
