UK renewables: will anything survive?

By Dave Elliott

The UK Department of Energy and Climate Change (DECC) seems to be on a mission to cut back support for renewables across the board – so as to save money. The scale and pace of change is stunning. Will anything be left? (more…)

Why not nuclear and renewables?

By Dave Elliott

Nuclear plants do not generate carbon dioxide, so why can’t we have nuclear AND renewables, supporting each other, as a response to climate change? In evidence to the Energy and Climate Change Select Committee in July Amber Rudd MP, DECC Secretary of State, suggested that despite its high cost nuclear baseload ‘enables us to support more renewables’ and was needed since, ‘as we all know, until we get storage right, renewables are unreliable’. Can nuclear really support renewables, and is it really low carbon?

Germany stays on course

 By Dave Elliott

Germany is sticking to its ambitious plan to get at least 80% of its electricity from renewables by 2050. As part of that, it aims to support the construction and operation of 20 offshore wind farms, 7 GW in all, and that plan recently received a boost, with the European Commission agreeing that it did not conflict with EU state aid rules. The 17 wind farms in the North Sea and three in the Baltic will further EU energy and environmental objectives without unduly distorting competition in the Single Market, the EC said.

Green power in Asia – Part 2

By Dave Elliott

In my last post I looked at developments in China and India, where renewables have been playing key and increasing roles, with China clearly in the lead. By contrast, until recently, in Japan renewables had been given a low priority, but following the Fukushima nuclear disaster in 2011, Japan is now pushing ahead with some ambitious offshore wind projects, 1.45GW in all, using floating wind turbines, and a large solar PV programme, helped by lucrative Feed In Tariff subsidies.

Ditch climate arguments: they won’t help nuclear revive

By Dave Elliott

Steve Kidd, one time leading nuclear lobbyist with the World Nuclear Association, has had a rethink and left the WNA. In an article in Nuclear Engineering International he says ‘we have seen no nuclear renaissance’ and he outlines his new view- which is that the nuclear industry is in trouble and should stop using climate change arguments in its lobbying.

Nuclear – not the answer to climate change

By Dave Elliott

Although there are exceptions, as I noted in my last post, the UK being one, nuclear power seems to be in decline globally and this has led to what some might see as last ditch attempts to revive its fortunes. One such is the recent Open Letter to environmentalists, originating in Australia and backed by over 70 academics globally, though nearly half from Australia: http://bravenewclimate.com/2014/12/15/an-open-letter-to-environmentalists-on-nuclear-energy/   (more…)

New year, new nuclear: Hinkley fallout

A special extended bumper New Year edition

By Dave Elliott

The UK starts 2015 with a big new year headache- the Hinkley nuclear project. It is a huge uncertain project, and it is far from clear, if goes ahead, whether  it will prove to be a wise investment, given the fall in energy costs and the emergence of cheaper renewable alternatives. (more…)

WREC in London

By Dave Elliott

Some continue to portray renewables as marginal, with for example, ExxonMobil claiming that their potential is limited by ‘scalability, geographic dispersion,intermittency (in the case of solar and wind), and cost relative to other sources’, and renewables are only likely to make up about 5% of the global energy mix by 2040: www.ft.com/cms/s/0/5a2356a4-f58e-11e3-afd3-00144feabdc0.html?siteedition=uk#axzz33albsQ2B

Most however see renewables as booming, with IRENA looking to 30% or more of primary energy coming from renewables globally by 2030 (www.irena.org/remap). That is the sort of future envisaged, on the way to maybe near 100% of power by 2050, by most who attended the 13th biannual World Renewable Energy Congress, this one at Kingston University, London, in August.

Distributed energy: from supply to demand

By Dave Elliott

Energy networks and distributed energy resources in Great Britain”

The context for this IGov paper from Matthew Lockwood at Exeter University, UK, is the desirability of a fundamental shift in the underlying design of the energy system from the supply side to the demand side. It starts by quoting the words of Professor Strbac ‘The whole culture and philosophy of the system is based on a predict-and-provide mentality’. (more…)

Power out: keeping the lights on

By Dave Elliott

There is still large reserve capacity, but with some large old power plants closing, like the Didcot ‘A’ coal plant, the UK has found it a bit more challenging to meet demand when there are unexpected plant outages and cold weather. So will we make it through this winter? (more…)
