Small steps, big changes
In recent years availability of power in India has both increased and improved but demand has consistently outstripped supply and substantial energy and peak shortages prevailed in 2009-10. A high degree of caution is also needed as emerging economies like India may not at present have financial resources to leapfrog directly to cleaner mechanisms of energy.
In the past, the selection of an energy resource for electricity generation was dominated by finding the least expensive power generating plant. Although such an approach is essential, there is growing concern about other aspects of power generation such as social, environmental and technological benefits and consequences of the energy source selection.
It can be observed that coal has the maximum global warming potential followed by Natural Gas and others. Further, it needs to be re-emphasized that for India, like most developing countries, the cost of producing electricity is of paramount concern while planning for the type of plant to be installed and commissioned and more so with abundant supply of coal.
However, in the long run if we take the effect of the pollutants on human health and environment and cost as well as efforts needed to improve or alter the path of degradation, the initial higher cost of using renewable resources for producing energy may not be too big.
Increasingly around the world community level renewable energy sources are being deployed for multiple benefits for the community as well as the country as a whole. This packet of thought is not only blooming all around but has potential to sustain in longer run.

In recent years availability of power in India has both increased and improved but demand has consistently outstripped supply and substantial energy and peak shortages prevailed in 2009-10. There are also various estimates of 25000 to 35000 MW of power being produced by diesel generation to meet the deficits.
Such community level sources of renewable energy are not just eco- friendly but are comparatively cheaper to build as well as maintain. The maintenance is usually done by the local community members and needs no extra professional inputs. The bigger the project the costlier will be the pre and post construction charges.
Such small projects can sustain the local communities even in most adverse situations, as to say for example a 5KW hydro power project in Kinnaur district of Himachal Pradesh helped sustaining 3 villages when rest of the city was in darkness during chilling winter last year. This was a perfect example of a community, which are self sustained in terms of energy. This was just one example; there are many such examples to see.
In Germany more than 50% of its renewable energy comes from community level based system known as Energy Co-operatives, which was estimated to be about 900 last year.
Such small projects apart from being cheap, needs less land to put up the power plants/solar panels and hence causes less social impact due to displacement.
It allows more and more people to commit towards the environment and be a part of the solution. This helps in low carbon economy and helps them to be in control of their economic and environmental sustainability.
