Didcot power station is yet another power station out of action, but what does this mean for UK security of supply this winter?

The fire last week at Didcot power station has led once again to cries of “the lights are going to go out this winter”. But people who ask whether or not the lights will go out are asking the wrong question. It is politically inconceivable to allow non-consensual power cuts to happen in the UK this winter; therefore the question we should be asking is, “how much is it going to cost us to keep the lights on, and are there ways of reducing the cost?”

When the Didcot B gas-fired plant unit caught fire, the UK electricity system lost around 680 Megawatts of power generation. There is as yet no indication of how long it will take to get the unit up and running again, but it could be out of action for the rest of the winter.[i] To put this in context, UK peak demand for electricity is usually just under 60 Gigawatts, meaning that the fire cost the UK around 1% of total peak electricity consumption.

Will improved energy efficiency lead to increased energy consumption in the developing world? Quite possibly

A new report from the US Breakthrough Institute (BTI) provides evidence that historical improvements in the energy efficiency of lighting, steel and electricity production have led to greater energy consumption that would have been the case in the absence of those improvements. In other words, the ‘rebound effects’ have exceeded 100% (‘backfire’). The authors expect this experience to be replicated in industrialising economies, with the result that improved energy efficiency will contribute much less to reducing energy use and carbon emissions than is commonly assumed.

Response to Paterson’s unremarkable and nonsensical speech

Owen Paterson, the UK’s former Secretary of State for the Environment – and now scourge of environmentalists – made the most extraordinary speech a few days ago on climate change and energy policy[1].  The speech was a rare combination of the unremarkable and the nonsensical. Gordon MacKerron In the unremarkable category, Mr Paterson argued that climate change science was broadly right.   Equally, his endorsement of local combined heat and power and what he called ‘rational’ demand management are compatible with a suitably wide-ranging approach to countering climate change.  His scepticism about the achievability of an 80% cut in GHG emissions by 2050 is at least arguable, and his view that the attempt will be very expensive is almost certainly right – but probably much less expensive than the long-term cost of inaction .[2]

But most of the rest of his speech is deeply misguided and/or prejudiced.  The warning signs come early on in his appeal to ‘common sense’ – always a dangerous approach, as my common sense will rarely be yours, and is often a cover for deeply-held prejudice.   The idea of common sense also has the appeal of not needing scrutiny.   Among the ‘common sense’ ideas Paterson advocates is exploitation of shale gas and, somewhat bizarrely, the building of small modular nuclear reactors (SMRs).  Shale gas is of course something that the UK may well develop in a limited way, though at some political cost and offering no reductions in gas prices, as the UK is well integrated in a European market that will scarcely notice UK shale production.  So shale’s impact will at best be marginal, take several years to become even noticeable, and not likely to reduce greenhouse gas emissions.[3]  And his view that renewables are hopelessly expensive ignores the fact that there are major, ongoing cost reductions in many renewable technologies Read more ›

Neoclassical theory promises: a world of sustainable consumption

By Harry Saunders

Allow yourself for a moment to picture a time; say 5, 10, 50 generations in the future.  Imagine yourself in a world where everyone is consuming at a level that satisfies them.  People need to work only a small fraction of their time, and the need for work diminishes persistently so leisure time is ever-rising.  And the economic machine you see working there is automatically and continuously reducing its assaults on natural ecosystems globally.

Impossible, right?  As it happens, neoclassical economics says not.

Surprising as this might seem, would it further surprise you to learn this economic machine has all the trappings of a free market, competitive, private-ownership economy, including producers who maximize their profits?  And that this very dynamic is what propels and enables this “golden age” for households – and for the environment?

Why We Need to Shift Focus from Energy Supply to Reducing Demand

Mari Martiskainen asks whether it is time to have a real debate about moving our focus from energy supply to realising the benefits of energy efficiency.

The International Energy Agency (IEA) reported last week that the energy efficiency market was worth between $310 billion and $360 billion in 2011; thanks to energy efficiency improvements in buildings, transport and appliances, total final energy consumption in IEA countries has reduced by 60% during the last 40 years.

There is clear evidence that energy efficiency works, not only by reducing demand but also by contributing to a transition towards a more sustainable energy system. In the light of this, there is a clear need to have a more open debate about the role of energy efficiency in the UK’s energy policy. Read more ›
