    Contracts awarded for world's longest interconnector
    Plans to build a new interconnector between the UK and Norway that would provide the ability to import, export, and store clean power took a leap forward today with the award of €1.5bn of contracts relating to the ambitious project.
    The project, which is the latest in a series of interconnector investments National Grid is considering, will provide a major boost to the renewable energy sectors of both countries. It is designed to allow the UK and Norway to import and export renewable power based on respective supply and demand in each country and crucially would allow excess renewable power generated by UK wind and solar farms to be exported to Norway's pumped hydro-storage sites, effectively enabling the storage of intermittent clean power.


    [UK - Iceland interconnector would be even longer, if it gets built?]

    This piece on UK system capacity doesn't mention renewables...but it is all about them!

    Designers create the 'impossible' zero-carbon house
    Designers at Cardiff University say they have constructed the sort of house George Osborne once described as impossible.

    The chancellor scrapped a requirement for new homes to be zero carbon by 2016 because he said it would prove too expensive.

    But Cardiff University say they have built a house that exports more power to the grid than it uses.

    And crucially they say the cost fell within the normal budget for social housing.

    A government spokesman said house builders needed to be given more time to develop low energy homes.

    'Excess energy'

    The house took just 16 weeks to construct and cost £1,000 per sq m - that's within the range for social housing of £800 to £1,000 per sq m, the designers said.

    In future, they say its owners will make money from selling excess energy.

    The property, near Bridgend, has insulated render on the outside and air heating systems that rely on the sun.

    The designers say it will need to import energy in the winter, but the imports will be trumped by energy exports during summer months.

    Interestingly it has a 6.9kw li-ion battery system, supplied by this company, but no details on their web site that I can see: http://www.ecolek.co.uk/index.html

    Thought I'd bump this thread with a nice little story from New Zealand:

    Sun sets on coal power in New Zealand
    Energy company Genesis Energy said yesterday it will close New Zealand's two remaining coal-fired electricity generation units by 2018, effectively ending the country's use of coal to generate electricity.

    The remaining two generators are both located at the Huntly Power Station in Waikato on New Zealand's North Island. The plant's two other generators, which are gas-fired, will continue to operate.

    Albert Brantley, chief executive of Genesis Energy, said the falling cost of renewable technology was a major factor in the decision to retire the generators.

    "The development of lower cost renewable generation, principally wind and geothermal, investment in the HVDC link, and relatively flat growth in consumer and industrial demand for electricity have combined to reinforce the decision to retire the remaining Rankine units, which will deliver further operational efficiencies to Genesis Energy," he said in a statement.

    Renewables cover almost 100% of German demand ..... briefly.
    On Sunday midday, close to 100% of the electricity demand in Germany was covered by renewable sources. A lot of sun and wind made this possible.

    Given that the UK is a net electricity importer from France and France in turn is now a net importer from Germany, it seems logical to say we probably benefitted from Germany's bumper production too!

    Citi report: slowing global warming would save tens of trillions of dollars
    Citi Global Perspectives & Solutions (GPS), a division within Citbank (America’s third-largest bank), recently published a report looking at the economic costs and benefits of a low-carbon future. The report considered two scenarios: “Inaction,” which involves continuing on a business-as-usual path, and Action scenario which involves transitioning to a low-carbon energy mix.

    One of the most interesting findings in the report is that the investment costs for the two scenarios are almost identical. In fact, because of savings due to reduced fuel costs and increased energy efficiency, the Action scenario is actually a bit cheaper than the Inaction scenario.
    This conclusion soundly refutes the main argument against climate action – that it’s too expensive, with some contrarians even having gone so far as to claim that cutting carbon pollution will create an economic catastrophe. To the contrary, the Citi report finds that these investments will save money, before even accounting for the tremendous savings from avoiding climate damage costs.

    Possible good news for UK renewables.

    The costs of the French based nuclear reactor in Normandy are still escalating. This is the design to be used for 2 reactors at Hinkley C.

    The original 5 year and €3.3bn cost has already become 11 years and €10.5bn.

    Whilst it's unlikely to put the UK off continuing with the Hinkley project, which may start generating in 2025, I'm guessing that the falling cost of renewables even with large scale storage, might be a match for nuclear by that date.

    It would be a great shame if we began the new 35yr subsidy for nuclear at a point in time when a cheaper and cleaner alternative may be available. Worse still if domestic generation with storage is by then viable without support.

    However, large scale storage is still a major hurdle, so only time will tell.

    Some interesting numbers on popularity of renewables v's fracking. Even the Tory voters want wind (guess they shouldn't have voted Tory then!)

    67% of people (62% of Tory voters) are in favour of locally owned renewables. Also 78% want the government to help communities generate their own power and keep the profits ....... yet the government is proposing to slash the FiT subsidy?

    People prefer living near wind turbines to fracking wells – survey
