AbstractThis paper explores the non-nuclear options for supply side dominated electricity systems. The important questions are of emphasis and approach to the future. For instance, electricity demand could be reduced by around 10% by investments in efficient industrial motors, commercial lighting and domestic appliances and they would offer payback periods of four years or less.The favoured solution to the electricity supply question is of a mix of options. Given the availability of these options in the UK there is no need to have nuclear power with its substantial risks.
