Indian villages are spread over wide distances, most do not have large populations, and<br />

development levels are low. So they cannot provide the substantial loads that towns and cities can.<br />

Therefore, while supplying them electricity from a centralised electricity generation system requires<br />

long transmission lines and so is expensive, on the other hand for the same reason it also involves<br />

huge transmission losses.<br />

A very simple, efficient and cost-effective solution to this problem is making use of<br />

decentralized power generation systems (meaning electricity generated at or near the point of use),<br />

based on renewable sources of energy. These can be a mix of wind, micro hydel, solar and biomass,<br />

depending on the location and availability of local resources. (We discuss renewable energy sources<br />

in the next section.) Since a decentralized generation system is connected to a local distribution<br />

network, instead of a high voltage transmission system, the losses are very low. Even if the cost of<br />

electricity from this decentralized system is more than generation cost of conventional grid<br />

electricity, because of the huge costs and losses involved in transmitting the latter to remote<br />

villages, the real end cost of conventional electricity to the consumer would in most cases be more<br />

than decentralized electricity. And, as we see below, costs of decentralized electricity are rapidly<br />

falling, making it an even more attractive solution. Further, such a system is cheaper, produces less<br />

carbon emissions, has none of the environmental, health and social costs associated with large<br />

conventional power plants, and finally, also has the benefit that it empowers local people as they<br />

can easily control and manage the electricity supply system.<br />

Part IV: The Potential of the Alternate <strong>Energy</strong> Paradigm<br />

The above analysis shows that it is possible to solve India’s energy crisis with an Alternate<br />

<strong>Energy</strong> Paradigm, whose basic elements are:<br />

Maximising energy efficiency, including efficiency of the energy delivery system and end-use<br />

efficiency, and eliminating wasteful use of energy.<br />

Making the maximum possible use of renewable energy sources.<br />

Reducing load on the grid by promoting decentralized renewable energy supply systems.<br />

Given the huge scope of improving energy efficiency in the country, if the government indeed<br />

implements the energy efficiency measures outlined above, and promotes the use of decentralised<br />

energy systems to meet the energy needs of India's far-flung villages over half of which have still<br />

to be electrified sixty years after independence, then the additional grid electricity generation<br />

required for meeting our future growth needs is substantially reduced – a major portion of this can<br />

then be easily met from renewable energy sources.<br />

As discussed above, even the government admits the potential of grid connected renewable<br />

electricity generation in the country to be: 48,500 MW of Wind <strong>Energy</strong>, 15,000 MW of Small<br />

Hydro Power, and 21,000 of Biomass <strong>Energy</strong>, apart from at least 50,000 MW of Solar <strong>Energy</strong> (the<br />

government itself has set a target of 20,000 MW solar energy by 2022). dcxcii According to the World<br />
