In Re-energizing Britain Nigel Hawkins warns the UK faces blackouts unless the six major energy companies invest. New nuclear plant should be encouraged by replacing the existing Renewables Obligation with a new Low Carbon Obligation, which would include nuclear power. The three key aims of energy policy – security of supply, reduced carbon emissions, and lower prices – would all benefit from this change, since nuclear energy is both low-carbon and less expensive than many other ways of generating electricity, and does not depend on risky supplies of gas from Russia. The government also needs to work with the energy companies to make sure that they have both planning approval and access to finance to increase Britain's gas storage facilities substantially. The UK has only one-tenth of the gas storage of Germany, and is dangerously exposed to interruptions in supply.
