Renewable Energy and Energy Efficiency

India, a country highly vulnerable to the effects of climate change, has witnessed the devastating impact of cyclones in recent years. The increasing frequency and intensity of cyclones have raised concerns about the resilience of India’s solar rooftop photovoltaic (RTPV) systems. As the nation strives to transition to renewable energy (RE) sources, the RTPV industry has gained significant momentum.

To meet its global commitments, India is planning to reduce fossil-fuel-based power generation by targeting 500 GW of non-fossil fuel capacity by 2030. However, the increasing adoption of renewable and distributed energy resources is creating several technical and economic challenges in the Indian power system due to intermittency and lack of infrastructure.

India’s plans to add more than 200GW of solar PV capacity will include significant contribution of agriPV. Given the criticality of agriculture to the Indian economy and the diversity in crop production, there is need to understand in practical terms the impact of deploying agriPV on productivity, farmers incomes, linkages to foreign trade, domestic demand among other issues. This granular assessment must form the basis for developing clear guidelines, in consultation with stakeholders, on defining agriPV and parameters such as acceptable yield restriction.

Wind energy systems are expected to play a crucial role in meeting India’s ambitious goal of 450 GW of renewable energy installed capacity by 2030, which includes 140 GW of wind energy. In addition to large wind turbines, small wind turbines with less than 50 kW capacity can contribute to this goal. Further, small wind turbines generate decentralised power and reduce energy bills for consumers and power purchase costs for distribution companies, as well as help manage peak demand periods.

With an increasing number of countries setting strong net-zero targets, there is a global push for the gradual discontinuation of fossil-fuel usage and the large-scale adoption of renewable energy (RE). In this context, green hydrogen is seen as the fuel of the future, with various governments and energy companies betting on it.

In recent years, blockchain technology has made significant strides across various industries, from finance to supply chain management.

Novel and viable alternatives are warranted to achieve the 500 GW renewable energy target for 2030. Agrivoltaics (agriPV) is one such promising technology for optimising land usage by combining agriculture with PV.

Rooftop solar is expected to play a major role in India’s 280 GW solar target for 2030. However, only ~8 GW of the 40 GW target for 2022 has been achieved so far. The residential sector accounts for less than 20% of this installed capacity, despite being offered incentives such as net metering and a 20%–40% capital subsidy.

Of India’s nearly 62 GW installed solar capacity, about 50 GW is ground-mounted photovoltaic (PV) plants. Recent trends show that obtaining land parcels for large solar projects is becoming increasingly difficult. Innovative and viable alternatives are needed to reach the 450 GW renewable energy (RE) target for 2030. Among the buzzwords circulating in the upper echelons of policy and decision-making is ‘agrivoltaics’. The concept aims to optimise land usage by combining agriculture with PV (agriPV).
