Reducing carbon footprint by replacing generators with solar PV systems: a contingent valuation study in Lagos, Nigeria
Nigeria is endowed with abundant sunshine year-round; thus, solar PV would solve the environmental problems associated with petrol-powered generators. However, it is unclear whether households are willing to transition. Thus, we analyze households’ willingness to pay (WTP) for solar PV under four scenarios: (i) WTP when a solar PV is complemented with a generator, (ii) WTP when a solar PV completely displaces a generator, (iii) WTP when a solar PV is complemented with a generator, plus a subsidy, and (iv) WTP when a solar PV completely displaces a generator, given a subsidy. We find that WTP for solar PV is higher when it can displace generators completely. Subsidy plus monthly rather than upfront payment would scale up the adoption of solar PV by about 6 per cent. Furthermore, the cost benefit analysis results show that solar PV investment is profitable. Thus, there is a need to implement policies aimed at scaling up the energy transition.
期刊介绍:
Environment and Development Economics is positioned at the intersection of environmental, resource and development economics. The Editor and Associate Editors, supported by a distinguished panel of advisors from around the world, aim to encourage submissions from researchers in the field in both developed and developing countries. The Journal is divided into two main sections, Theory and Applications, which includes regular academic papers and Policy Options, which includes papers that may be of interest to the wider policy community. Environment and Development Economics also publishes occasional Policy Fora (discussions based on a focal paper). From time to time the journal publishes special issues based on a particular theme.
