Analysis findings and conclusions derived
Bolpur, a fairly popular tourist city in West Bengal, shows us that while it excels in certain aspects in contrast to how bigger cities perform, it also lacks in certain areas where it has higher rates of energy consumption.
The inner core area of the city is densely populated, which gives it the benefit of heat retention effect, as a result of which, heat from the surrounding areas is much less likely to be able to penetrate into the core. Consequently, less heat requires less artificial cooling, which reduces energy consumption. It also gives the added advantage of having highly accessible neighborhoods, where one can move within the city using active transport. Majority of the people here have their own bicycles and motorcycles which they use for transportation purposes.
Water bodies are also fairly abundant and uniformly distributed all over the city, making it easy for evapotranspiration to take place and effectively decrease the average summer temperatures and therefore, reducing the energy consumption due to artificial cooling mechanisms.
Although artificial cooling with the help of electricity is always high in demand, one hurdle that many small cities in India face today, Bolpur being no exception, is the lack of 100% coverage of electricity. Even though, electricity generation is not entirely a 100% efficient process yet, there is no doubt that electricity is still the most efficient medium of utilization of energy.
Bolpur, although it currently lacks any solar power generation measures, has an applaudable resolution of powering all government buildings through solar power within this decade. This is something which small-sized cities can take inspiration from, as solar power generation has a very low barrier in terms of infrastructure requirements in comparison to other popular renewable sources of electricity.
Bolpur also has the added benefit of being near an area with high geo-thermal potential (Bakreshwar). While the infrastructure cost of a geo-thermal power generation system is high, it is a worthy long-term investment.
While building geo-thermal power generation infrastructure is an expensive and difficult process, a district cooling system is something that any city can install and readily benefit from. It can cut down the commercial and institutional cooling load by up to 50%. In the case of Bolpur, there are two energy intensive locations which can make use of this system to save energy.
In addition to the above, Bolpur can also immensely benefit from replacing its entire HPSV street lamps infrastructure with LED street lamps, as they can cut down on street lamp energy requirements by half.
Finally, to make sure that the power distribution mechanism is also functioning efficiently, smart metering system can be implemented wherever possible, as it can monitor and prevent T&D losses. Since small cities have lesser population, the installation cost of smart meters can be significantly lower and therefore, can be a great investment to monitor citywide electricity usage and improve energy efficiency of the city.
