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.

PV solar in Germany

By Dave Elliott

PV solar continues its spectacular price reduction and that’s led to large-scale deployment, as in Germany, which now has around 36GW in place, and globally, with around 180 GW. PV was initially expensive, but prices are now much lower, thanks in part to Feed In Tariff systems around the EU, as under the EEG law in Germany, which has helped create a large market. With FiT levels now cut, will it continue to expand?

Wind power around the world

By Dave Elliott

Wind power is booming globally, with over 370GW of electricity generation capacity installed so far. It could jump to 2,000 GW, more than five times its current level by 2030, supplying up to 19 % of global electricity, the Global Wind Energy Council says, although that would require ‘unambiguous commitment to renewable energy in line with industry recommendations … [and] the political will to commit to appropriate policies’.

Wind power in the UK- still on the up

By Dave Elliott

Wind energy is doing well in the UK. There were periods last year when the UK’s 11GW of wind plant met up to 15% of power demand, over-taking nuclear, and even briefly achieved 24%: www.carboncommentary.com/2014/10/06/wind-power-exceeds-nuclear-output-for-a-few-minutes/

While there have been no shortage of complaints about the alleged high cost, Cambridge Econometrics has calculated that wind plants saved the UK £579m in fossil fuel imports in 2013: www.camecon.com/Libraries/Downloadable_Files/The_impact_of_wind_energy_on_UK_energy_dependence_and_resilience.sflb.ashx (more…)

Down on wave and tidal farms

By Dave Elliott

In my last post I looked at how solar farms were being constrained in the UK. But they are not alone. Marine renewables are also facing problems. Tragically, pioneering wave energy company Pelamis has gone into administration, after failing to secure development funding. And Siemens is to sell off Marine Current Turbines (MCT), the pioneering UK tidal company it look over in 2012, due to the slow pace of orders. Aquamarine Power, who have developed the Oyster inshore wave device, is also to “significantly downsize” its business. (more…)

Down on solar farms

By Dave Elliott

Solar, wave and tidal farms represent new ventures, adding to the renewable energy repertoire. But they are facing problems, in terms of finance and government support priorities, as I report in this two-part review of the UK situation, looking first at solar PV.

The good news is that PV solar overall is doing well in the UK, with more than 5GW in place, including roof-mounted arrays on private houses and the first wave of solar farms in fields. DECC says 10GW may be possible by 2020, perhaps even 20GW: https://www.gov.uk/government/publications/uk-solar-pv-strategy-part-1-roadmap-to-a-brighter-future  But DECC- and DEFRA -are  less keen on solar farms.

Capacity Market – the first UK auction

By Dave Elliott

In a fully free-market energy supply system there is no direct commercial incentive for generation companies to ensure that the lights stay on long term, by investing in new and/or backup capacity. Given that some old plants are scheduled for closure and more reliance on sometimes variable renewables is planned, the UK government has stepped in to create a new ‘capacity market’ to try to fill the potential gap in terms of reserve capacity and grid balancing capacity.

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…)

Facts and fiction

By Dave Elliott

Is the truth out there? An extended Xmas Whimsy

It’s usual for there to be a spread of viewpoints on most issues, and it’s always worth looking at a range views, including ‘outlier’ ones! On that, this is fun: www.xonitek.com/press-room/company-news/the-stone-age-didnt-end-because-they-ran-out-of-stones/

However at times you can get weary of obsessive time wasters and yearn for clarity! Sadly that may not be easy to achieve.
