Land and clean energy trade-off: estimating India’s future land requirement to fulfil INDC commitment

Abstract

Purpose For India, with its low agricultural productivity and huge population, land acquisition has always been a serious policy challenge in the installation of land-intensive power projects. India has experienced a large number of projects getting stalled because of land conflict. Yet, there is a paucity of literature pertinent to India that tries to estimate future land requirements taking into consideration of land occupation metric. Design/methodology/approach In the present study, the dynamic land transformation and land occupation metrics of nine energy sources, both conventional and renewable, are estimated to further determine the magnitude of land requirement that India needs to prepare itself to fulfil its Intended Nationally Determined Contribution (INDC) commitments. This is illustrated through two different scenarios of energy requirement growth rates, namely, conservative and advanced. Findings This analysis suggests that, while nuclear energy entails the lowest dynamic land transformation when land occupation metric is taken into account, waste to energy source possesses least land requirement, followed by coal-fired source. Hydro energy source has highest requirement both in terms of dynamic land transformation and land occupation. It is also seen that land requirement will be 96% and 120% more in INDC scenario than business as usual (i.e. if India continues with its current share of renewables in its energy portfolio in 2030) considering a conservative and an advanced growth rate, respectively. Research limitations/implications Some policy recommendations are provided that may aid policymakers to better address the trade-off between clean energy and land and incorporate it into policy planning. This study has not been able to consider future technical efficiency improvement possibilities for all energy sources, which can be incorporated in the proposed framework for further insight. Originality/value This paper provides a framework for estimation of future land requirement to fulfil India’s INDC energy plans which is not available in existing literature. The authors confirm that this manuscript is an original work.

“…On technology front Solar PV and CSP scores are the highest for Bharat. According to Ernest and Young on "Renewable Energy Attractiveness Index" the country stood second position in 2017 [9]. Given this edge it should move forward with continuous innovation and increase solar energy generation capacity to 200 GW and extend the number of solar parks to 100 by year 2030 leading to sustainable competitive advantage.…”

Keeping this in view Bharat is committed to address these issues at top of the mind [4] with a pledged to reduce carbon emissions approximately 35% by 2030 [9]. In the latest development at G20 summit in Rome, global leaders agreed to limit global warming by 1.5 Celsius.…”

India’s emerging fuel mix for 2050: actions and strategies to decarbonize the transport sector

“…By 2050, India’s renewable infrastructure will have broad-scale projects linked to a centralized grid to relay by open connectivity for heavy industrial and commercial purposes (Tubridy, 2020). Public utilities will use certain portions of it to meet their renewable procurement obligation (Rej and Nag, 2021). The grid provides electricity fed from solar parks with high-voltage evacuators under green corridor projects.…”
