CSTEP's Techno-Economic Model for Photovoltaics (CSTEM PV) has been envisioned as a continuing initiative that aims to constructively support and be in line with India’s clean energy aspirations.

COVID-19 is glaringly revealing the vulnerability of the systems we rely on. Paradoxically, factors that increase vulnerability to COVID-19 are also the ones that enhance vulnerability to climate change, such as income inequity, inappropriate and inadequate housing, employment type, age, and existing health conditions. This is a cause of concern, as both the crises impact the most vulnerable — the homeless, migrants, poor, the marginalised — who already have low or no access to food, housing, healthcare, water and sanitation.

GIS can play a significant role in addressing the data gaps in the current energy auditing processes followed by DISCOMs. GIS locates the coordinates of the feeders, transformers and consumers and helps in mapping the entire distribution system. Such a system would help DISCOMs track and manage their assets. Visualising this information will also enable accurate ‘tagging’ of consumers to their respective feeders and transformers — known as consumer indexing.

• Modeling was performed for solar thermal-biomass hybridization for power generation.

• Increment in capacity reduces the solar collector area per MW to 5,000 m2 (20 MW).

• Annual biomass requirement per MW reduced to 1600 tonnes at 20 MW scale.

• Hybrid mode of operation increases the plant capacity utilization from 23% to 47%.

• Cost of electricity by the hybrid plant is INR 6/kWh for plant capacities >5 MW.

In think tanks, visual communication happens at multiple levels and in various forms, for example, process diagrams, graphs, progress reports, and infographics. However, researchers face several challenges in incorporating such visual elements in their documents. For example, the researcher might find it difficult to strike a balance between text and visual content; the process might be time consuming because it has to be outsourced; the researcher might not be convinced of the design.

Burning the generated straw in a closed system like a cement kiln, where the exhaust gas adheres to pollution norms, can significantly curb the woes of stubble burning. Every kilogram of rice produced implies 0.7-1.4 kg of rice straw, which means 4-8 million tonnes of straw being burnt on the fields in Punjab and Haryana collectively. The straw can produce as much as 50-100 petajoules (PJ) of energy. This can be used in cement kilns to meet the thermal energy demand for producing cement.

Solar power plants are expected to play a significant role in India’s power sector. The country plans to achieve an installed capacity of 100 GW by 2022. However, in a stand-alone mode, solar power plants are not able to deliver a consistent power supply, as per the demand requirement, to Electricity Supply Companies (ESCOMs). This is mainly because of the nature of intermittency associated with solar energy.

The maintenance aspect of solar installation is currently a shy topic and not adequately discussed. To make solar energy a success story, we must embrace its nature completely and support it the right way to make it a sustainable solution. Even a simple step such as cleaning the modules the right way could support a bigger idea of an effective clean energy solution.
