It is essential that we mitigate the emissions of greenhouse gases and thus avoid some of the worst impacts of climate change that would take place in coming years and decades. Mitigation would require a major shift in the way we produce and consume energy. A shift away from overwhelming dependence on fossil fuels is now long overdue, but unfortunately, technological development has been slow and inadequate largely because government policies have not promoted investments in research and development, myopically as a result of relatively low price of oil. It is now, therefore, imperative for a country like India to treat the opportunity of harnessing renewable energy on a large scale as a national imperative. This country is extensively well endowed with solar, wind and biomass sources of energy. Where we have lagged, unfortunately, is in our ability to develop and to create technological solutions for harnessing these sources. One particular trigger for carrying out the urgent mitigation of greenhouse gas emissions is the Intergovernmental Panel on Climate Change (IPCC) clearly shows the need for reducing the greenhouse gas emissions by 2030. Why do we continue to depend on fossil fuels heavily? 1.Inadequate technological development 2.Inadequate funds for research and development 3.Inadequate availability of alternative sources of energy
