    We've seen some debate on this thread about the relevance of some posts to the topic.

    To ensure the thread remains on topic for forumites wanting to discuss the latest news we're asking that all posts contain a link to the news you're discussing.

    For the purposes of this thread the "news" needs to be within the last two weeks.

    Back to Martyn1981's original post.

    ---

    I thought it might be a good idea to have a thread for posting general news items that may be of interest.

    PV and the 'Solar in the news' thread attract a lot of interest, so here's a thread for all the other goings on.

    FIT ended, why anyone is still wasting time discussing it, other than as a model for the future escapes me.

    Also, definitely not news

    The 'news' element was the Election discussions where Farage raised the wider issue of Green Taxes where the 'poor' are subsidising the 'rich'.

    Were' gonna need bigger wellies.

    Greenland's ice sheet melting seven times faster than in 1990s

    Greenland’s ice sheet is melting much faster than previously thought, threatening hundreds of millions of people with inundation and bringing some of the irreversible impacts of the climate emergency much closer.

    Ice is being lost from Greenland seven times faster than it was in the 1990s, and the scale and speed of ice loss is much higher than was predicted in the comprehensive studies of global climate science by the Intergovernmental Panel on Climate Change, according to data.

    That means sea level rises are likely to reach 67cm by 2100, about 7cm more than the IPCC’s main prediction. Such a rate of rise will put 400 million people at risk of flooding every year, instead of the 360 million predicted by the IPCC, by the end of the century.
    Oceans have absorbed most of the excess heat arising from our disruption of the climate to date, and much of the carbon dioxide, but they are reaching the limits of their capacity to do so. Sea level rises are driven not only by melting ice but by the thermal expansion of the seas as they warm.

    The scale and speed of the ice loss surprised the team of 96 polar scientists behind the findings, published on Tuesday in the journal Nature. The Ice Sheet Mass Balance Inter-comparison Exercise comprised 26 separate surveys of Greenland from 1992 to 2018, with data from 11 different satellites and comparisons of volume, flow and gravity compiled by experts from the UK, Nasa in the US, and the European Space Agency.

    I'm getting old, I can still remember when this would have been considered big.

    93 MWh Tesla Megapack Coming To Alaska To Save Customers Cash

    A new 93 MWh Tesla Megapack system installed in Alaska by the Homer Electric Association, Inc., will be used to directly offset electricity that would have otherwise required a peaker plant to fire up. The new battery pack will be installed at the Soldotna Power Plant (map), adjacent to the existing natural gas-fired GE LM 6000 turbine currently used to provide electricity to cover peak usage in the area.
    Notably, the local electricity cooperative opted to install the new Tesla Energy system as a way of creating a more flexible grid to accommodate more intermittent renewable assets on the grid in the future. Batteries not only serve as peaker units for a grid operator, they are a source of flexibility, one of the most valuable metrics for any grid operator when it comes to keeping everything humming along reliably.

    Not sure that all my peers (old white men) will be as happy as me, but this is great news, certainly helps to raise the profile of the climate crisis too:

    Greta Thunberg named Time magazine's person of the year

    Greta Thunberg, the teen activist from Sweden who has urged immediate action to address a global climate crisis, was named Time magazine’s person of the year for 2019 on Wednesday. She is the youngest person to have ever received the accolade.

    Thunberg, 16, was lauded by Time for starting an environmental campaign in August 2018 which became a global movement, initially skipping school and camping out in front of the Swedish parliament to demand action.

    “In the 16 months since, she has addressed heads of state at the UN, met with the pope, sparred with the president of the United States and inspired 4 million people to join the global climate strike on September 20, 2019, in what was the largest climate demonstration in human history,” the magazine said.

    “Margaret Atwood compared her to Joan of Arc. After noticing a hundredfold increase in its usage, lexicographers at Collins Dictionary named Thunberg’s pioneering idea, climate strike, the word of the year,” Time said.

    Greta Thunberg Is TIME Person Of The Year

    Thunberg’s message is simple. “We can’t just continue living as if there was no tomorrow, because there is a tomorrow. That is all we are saying.” What she means is that if the world continues to pour the waste products that come from burning fossil fuels, the Earth’s ability to support human life will be severely degraded if not destroyed altogether.

    'Drill baby drill' ...... no I haven't gone to the dark side:

    The Boring Company + Pumped Hydro: Proposal For Elon Musk — CleanTech Talk

    When most people think of pumped storage, they think of putting a dam on a river and pumping water from below the dam to the top. In fact, as Mike explains, putting a dam on a river has huge environmental impacts, including changes in upstream and downstream ecosystems and carbon dioxide emissions from decomposing vegetation. Instead of blocking a river, closed-loop pumped-storage hydropower significantly reduces environmental impacts and dissipates much of the controversy surrounding hydropower and dams. Furthermore, Mike believes that for closed-loop pumped-storage hydropower, there is a hundred times more resource potential than our storage needs globally.

    Divestment from FF's is looking more and more sensible. [Note that FF company values reflect their known reserves, and those reserves total far more than the accepted max carbon budget before runaway global warming would be unavoidable, so they can never be extracted anyway.]:

    Chevron Will Write Down Its Assets By At Least $10 Billion

    Chevron announced this week it will write down the value of its assets by between $10 and $11 billion in the fourth quarter of this year, according to a report by the Associated Press. The reason for the write-down is oil and natural gas prices that stubbornly refuse to rise despite increases in demand. Those lower prices mean the value of the company’s stated reserves is less than anticipated. More than half the write-down is related to gas drilling operations in Appalachia.
    Such write-downs are becoming more commonplace in the industry. Last week, Spanish oil company Repsol took a $5.3 billion write-down of its oil and gas assets as part of its promise to reduce carbon emissions from its operations and products. In late October, BP took a $2.6 billion charge after it sold some US assets as part of a $10 billion divestment plan. The sale brought lower than expected prices, a further indication that the industry may be facing serious financial trouble in the months and years ahead.

    Big day for politics, EU politics:

    Info on the proposed European Green deal:

    European Green Deal will change economy to solve climate crisis, says EU

    Nearly every major aspect of the European economy is to be re-evaluated in light of the imperatives of the climate and ecological emergency, according to sweeping new plans set out by the European commission on Wednesday.

    The comprehensive nature of the European Green Deal – which encompasses the air we breathe to how food is grown, from how we travel to the buildings we inhabit – was set out in a flurry of documents as Ursula von der Leyen, the new commission president, made her appeal to member states and parliamentarians in Brussels to back the proposals, which would represent the biggest overhaul of policy since the foundation of the modern EU.

    Von der Leyen said the package was aimed at economic growth and increasing prosperity. “[This] is our new growth strategy, for a growth that gives back more than it takes away,” she said. “It shows how to transform our way of living and working, of producing and consuming, so that we live healthier [lives] and make our businesses innovate. We will help our economy to be a global leader by moving first and moving fast.”

    But three countries are holding out, particularly Poland which gets 80% of its leccy from coal:

    EU leaders meet to try to agree on carbon neutrality by 2050

    European leaders meeting at a summit in Brussels will make a new attempt to set the European Union on course for carbon neutrality by 2050, in a test of the bloc’s credibility on the climate emergency.
    Most EU member states support the plan to make the EU carbon neutral by 2050 but Hungary, Poland and the Czech Republic are refusing to sign up, raising the prospect of a dramatic setback for Europe’s green credentials in the final days of the UN climate conference in Madrid.

    Failure to agree the EU-wide target a second time, after a previous attempt in June, would be a blow to the European commission president, Ursula von der Leyen, who on Wednesday set out her vision for a green deal that would transform every aspect of economic life.

    The green deal – a sweeping plan to change food production, industry, transport, buildings and energy use – is based on a target for net-zero carbon emissions by 2050. Von der Leyen wants a €100bn (£84bn) fund of public and private money to help countries abandon fossil fuels, in addition to a plan from the European Investment Bank to incentivise €1tn of green investment between 2021 and 2030.

    Renewables 'top UK investors chart'

    Nice! "New renewables" (wind+solar) are now firmly the largest source of low carbon electricity at 54.5 TWh for the last 12 months (Dec 2018-Nov 2019), with nuclear second at 51.1 TWh. See https://www.mygridgb.co.uk/last-12-months/

    To me it makes sense to group these two together, separately from biomass and hydro as the former are highly scalable while the latter aren't (lack of many suitable sites for much new hydro, limits of photosynthesis limiting biomass).

    There is still some way to go to beat the 84 TWh that nuclear generated in 1997 though, according to https://www.world-nuclear.org/country/default.aspx/United%20Kingdom

    Half the UK reactors close 2023/4 most the remaining half close 2028/30 so a lot of the 2020s will be a case of taking three steps forward two steps back

    If I'm not mistaken the plan is to add 20GW of offshore wind during the 2020s with no significant solar or onshore planned. This 20GW of offshore wind should produce about 70TWh of electricity if none is curtailed (some will be since even today we sometimes curtail) while 50TWh of nuclear will be lost

    So 70 steps forward 50 steps backwards

    Germany is in a similar boat they will close all their nukes within three years losing some 80TWh of non carbon output. 2024 will be worse CO2 than 2021 for the Germans

    Plans are to spend the 2020-30 period adding

    +45TWh offshore wind
    + 55TWh onshore wind
    + 45TWh solar PV
    = 145 TWh

    So 80 steps back 145 steps forward and that's assuming they actually hit their solar and wind targets which they may not do because their total PV capacity alone exceeds their summer demand so either affordable batteries better happen or their wind and solar plans will not be implemented at this scale


    Germans shouldn't have closed their nukes which were doing 150TWh a year more than all their planned 2020-2030 wind/PV expansion

    I think you're right to separate hydro and biomass, as you say. Also bio-energy has flexibility so that will help with variable RE generation.

    Only guessing, but inspired by your 'another milestone' of peak nuclear, but that suggests to me the need for around 7GW of additional off-shore wind, and I think we have something like that in the pipeline (CfD approved but commissioning dates up to ~2026), so lots of records to keep falling.

    Success, sorta, kinda, well certainly great progress at least:

    European Green Deal to press ahead despite Polish targets opt-out

    European Union leaders have vowed to press on with a major economic plan to confront the climate emergency, despite Poland’s opt-out from a net-zero emissions target by 2050.
    “The European council [of EU leaders] endorses the objective of achieving a climate-neutral EU by 2050, in line with the objectives of the Paris agreement. One member state, at this stage, cannot commit to implement this objective as far as it is concerned, and the European council will come back to this in June 2020,” states the text, which was agreed after hours of wrangling over timetables and money.

    More greening of energy than green energy, but I think it sits well here, so we have a UK idea to suck air from roads at busy intersections and filter it, cool idea, hope it works/is practical.

    Roadside Filters Could Scrub 99% Of Air Pollution

    The reduction of air pollution and the health problems it causes are among the biggest factors driving (sorry) the grown of low-carbon, clean air initiatives from power companies and automakers. And, sure, reducing the output of harmful emissions is a necessary thing, but what can we do about the pollution that’s already out there? That’s the question being asked by UK-based firm Pollution Solution, and its answer is a new “cat’s eye-style” in-ground filter that the company claims will be able to substantially reduce air pollution at busy intersections.

    6.6MW for a new off-shore wind turbine, I suppose that's OK, but not exactly impressive ...... sorry ..... what ..... on-shore WT ..... seriously ....... FLIPPING HECK!

    Siemens Gamesa confirms debut deal for onshore titan

    Siemens Gamesa has confirmed a first order for its next-generation 5.X onshore turbine platform with a deal to supply 6.6MW-rated hardware for the 231MW Skaftasen wind farm.

    The German-Spanish manufacturer will deliver 35 5.8-155 machines, with the flexible power rating up to the higher level, covered by a 30-year service agreement to developer Arise AB and investor Foresight Group.

    Installation will take place in the second quarter of 2021.
    I wonder what the capacity factors will be?

    Big news for Germany as this will be the first year wind generation tops the charts, pushing lignite (brown coal) down into second place.

    Wind is at 24% of generation, and RE at ~46%, with FF gen at approx 40%.

    Wind overtakes lignite as Germany's primary power source for the first time in 2019
