Abstract

A key benefit of microgeneration is reduced carbon dioxide emissions during operation, compared with conventional energy technologies. This benefit must however be weighed up against their environmental ‘costs’, including the ‘embodied’ carbon dioxide emissions associated with their manufacture.

This chapter describes the life cycle assessment (LCA) of four micro-generators – micro-wind, solar PV, solar hot water and fuel cell micro-CHP. It then focuses on one aspect of environmental performance – the carbon footprint – and compares operational savings with embodied carbon to calculate the carbon payback period for each microgeneration technology.
