The Government’s commitment to increasing the share of the UK’s energy supply from renewable and low-carbon technologies has focused mainly on the potential for reducing carbon emissions. We approach it by investigating the differing impacts of differing kinds of renewable and low carbon technologies on the overall security of energy supply over different timescales.
In the very short term, the deployment of more intermittent generating capacity may present challenges to security of electricity supply and that the cost and manageability of these challenges is not well established at present above certain levels of penetration. Over longer time horizons, however, a higher penetration of renewable energy makes a positive contribution to security of fuel supply and in the very long term the fuel inputs to renewable energy are abundant.
