To answer this question, we start with the context of the best scientific evidence
on climate change, accepted by the Government, which means that as a nation
we must at least reduce our greenhouse gas emissions by 60% from the 1990
levels by 2050. Increasingly, a consensus is emerging that this will not be
sufficient to stabilise global greenhouse gas concentrations at a safe level.
To this we must add issues of security of supply, and not just in the short term.
We have a significant amount of our generating capacity, both coal and nuclear
fuelled, that is reaching the end of its useful life, and unless it is replaced in a
timely fashion we will have an electricity crisis which will lead to an
unsustainable economy. Our network infrastructure is also old, and we need to
invest in the transmission and distribution system for the coming half century.
Electricity offers some of the most cost effective ways for reducing greenhouse
gas emissions. Some countries already run electricity systems where greenhouse
gas emissions are extremely low – admittedly either using special circumstances
(such as Sweden or Switzerland) or decisions which the UK has not yet accepted
(such as the high proportion of nuclear power in France). Nonetheless, a
sustainable energy system is one which is going to be characterised by very low
emissions of greenhouse gases, probably as much as a 90% reduction from 1990
levels.
Heat represents some 47% of our greenhouse gas emissions. We do not produce
and use our heat very efficiently. Heat is wasted through losses from our buildings
and inefficient boilers, and we have waste heat from power plants and other
parts of the electricity system, that could be captured and used. A radical increase
in the efficiency of heat use is part of a sustainable energy system. Moreover, we
produce virtually all of our heat using fossil fuels, and we need to move
aggressively to decarbonise the system through introduction of such fuels as
wood pellets, other biomass, biogas, solar thermal, ground source heat pumps,
etc.

All of these changes in the direction of a dramatic reduction in greenhouse gas
emissions should also be completely aligned with improved energy security,
requiring a lower level of imported fuel.
What are the barriers to achieving this radical vision? And how do they relate to
the regulatory system we have in place?
• There is a short term price focus on the part of Ofgem. This is important
for today’s customers, but if we are to achieve a sustainable energy
system a longer term view, and a broader understanding of the interests
of future customers, will be necessary. Today we have Ofgem trying to
deliver low cost energy as sustainably as possible, and we must move to
sustainable energy delivered at the lowest possible cost.
• There are big gains to be made from energy efficiency measures, but
stakeholders must gain confidence that Government is serious about this,
and sees the value that can be obtained when carbon reductions are
coupled with improved energy security and affordability. Efficiency efforts

must move from the big industrial users of energy to large/medium/small
commercial users and households.
These barriers are significant, but the power to overcome many of them is within
the remit of Ofgem today. And where it is not, Government can and must help to
move the situation forward if we are to achieve our long term goals.
