Renewables

Last week I wrote about the forthcoming independence referendum in Kurdistan. To move from events there to what is happening in Scotland is a surreal experience. In Erbil the vote will be a deadly serious matter which could create a new country for a nation which as they say has no friends but the mountains having been a victim of international betrayal and cynicism for centuries. There is no knowing whether the Kurdish referendum will end in triumph or tragedy. In Edinburgh what should be an equally serious debate about breaking the relationship with the rest of the UK is now close to a farce. Read more

Why are renewables moving so slowly? Of course the output of renewable energy is growing in absolute terms and in terms of market share in most countries in the world. But the growth starts from a very low base. On the International Energy Agency’s latest numbers, renewables provide just 13 per cent of total global energy needs at the moment, and will provide only 18 per cent by 2035. If traditional biomass is excluded the figures are 7 per cent and 14 per cent.

The problem is cost. Electricity produced from offshore wind and solar costs somewhere between 50 and 100 per cent more per MW/hr than power from natural gas and, with some variations, will continue to do so for the next decade unless one makes the assumption that gas prices are going to increase. Onshore wind is cheaper and in the US in particular is the closest of all the renewables to being competitive without subsidies. Read more

France has a new energy policy. Although some saw the statement presented for debate in the National Assembly ten days ago as simply political rhetoric designed to draw green support behind the Government, beyond the fine words and long term aspirations some of the tough immediate steps being taken suggest that the shift could be more serious. If so the statement will mark the beginning of a gradual but inexorable run down of the French nuclear business. Read more

A 220-page document entitled “Commission Staff Working Document: In-depth study of European Energy Security” is hardly designed to be a best-seller. Few outside Brussels will read the European Commission paper in full, which is a pity because it is an excellent piece of work. It also provides the basis for a series of proposals contained in an accompanying document, which if accepted and carried through could create a common energy policy for the EU comparable in scale, scope and cost to the Common Agricultural PolicyRead more

Energy storage has long been regarded as something close to a holy grail. Of course, there are ways of storing some forms of energy – using pumped water or compressed air for instance. There are conventional batteries – and there have been advances in their capacity over the last few years. But the search for storage systems which are simultaneously economic and practical for use at scale in the modern energy market has long been a source of frustration.

Recent advances made by scientists in the US suggest, however, that real progress is now being made and that major breakthroughs are close. The whole of the energy sector should be watching because any such breakthrough could transform the economics of the whole industry. Read more
