The document discusses renewable energy as a viable option for power generation. It notes that worldwide renewable energy capacity and potential is large, but current consumption is still low, especially for new renewables like solar and wind. However, the scenario is changing rapidly as these sources are being aggressively adopted due to factors like rising fossil fuel prices, environmental pressures, and the need to electrify rural areas. The document uses India as a case study, where over half a billion people lack electricity access. It argues that solar and biomass power are already financially viable options in many remote areas compared to conventional fuels. The projected cost of coal power is also increasing more than previously estimated, suggesting grid parity between coal and solar could be achieved by 2015
