SOLAR ENERGY-THE CRUX OF FUTURE

AIM: Our aim was to harness solar energy for sustainable development.
OBJECTIVES: Optimum utilization of harnessed energy without any wastage in order to meet the rising energy demands via net metering.
A gradual shift from coal fired energy to carbon free energy for economic sustenance without any environmental degradation. Methodology: Our research is divided in three parts,
- Survey Method,
- Experimentation method and
- Comprehensive study.
Survey Method: In survey method we segregated the institutes into 2 parts. Institutes with solar panels and institutes without solar panels. The institutes which did not have solar panels, measured the terrace area deducted 30% from it, found out the capacity that could be installed. We took example of our very own school Don Bosco. We conducted our study in 3 parts before installing solar panels, on installing 10KW of solar panels, and when we will install 90KW of SPV (Solar Photo Voltaic panels) in future with net metering. We have seen that on installing 10KW of SPV we showed a saving of Rs500 every month. When we went into deeper study we found out that because there was no net metering, we were paying for what we generate during holidays and vacations. When we will install 90KW of SPV with net meter we will not only be energy sufficient but also export energy to other institutes.
Net metering is a bi directional meter through which a SPV system owner is allowed to sell the excess energy generated by him to the utility grid .But in our school the energy generated is recorded by a normal electric meter and it is assumed that the energy is imported from the grid. So we are paying for what we are generating during holidays and vacations. But many institutes which we surveyed are benefiting by net metering. They were getting the credit of what they were generating in excess. They avoided the high maintenance of solar batteries. There was no need for them to buy backup generators as the grid become the backup for the and above all they contributed towards saving fossil fuels and reducing carbon footprint.
Comprehensive study: Coming to the comprehensive study. We studied the entire area of Maharashtra. There are 20 coal plants in Maharashtra. We calculated the energy they generate. The coal they generate the water that is wasted in this progress and the CO2 (carbon-dioxide) emissions. In Maharashtra the energy generated from non-renewable sources is 91%.here due to the use of coal the carbon dioxide emissions are high. For a solution to this problem we took 50% 0f the barren land in our state for solar panel installation. We found that the green energy produced from this is more than all the thermal plants put together. Now comparing the present and the future scenario. In the present scenario the CO2 emissions are high and carbon credit is low due to the use of coal. In the future scenario due to the use of solar panels the energy from renewable resources will be 95.5% here the carbon credit will be high and the CO2 emissions will be low. This is a welcome change. This change can bring about upliftment of rural areas. It improves the GDP (Gross Domestic Product). t will reduce the migration from rural areas to urban areas. This leads to uniform use of natural resources and proper management of the ecosystem. This progress is seen in states like Gujarat and Rajasthan and places like Chandigarh and cochin airport. We all know the cost of solar panel is high but the benefits of solar panels outweigh the cost. They reduce pollution, save fossil and produce green energy. Our dream for the state of Maharashtra is to make it energy sufficient with minimum depletion of natural resources. Switching to no carbon energy like solar SPV is a great gateway to sustainable development
