    News from Germany as they move on to the next stage, and aim to remove coal.

    Germany to press renewables accelerator
    The German government is to accelerate renewables deployment in line with its 65% 2030 target, as it moves to phase out coal generation.

    In a bill launching this month, the country will commit to phasing out coal-fired power generation.

    Regarding Germany, here is a great link to see what they've done over the last 30yrs. They have reduced FF consumption, but there's also the counter argument that had they decided to run their existing nuclear fleet to their full life potentials, then they could have displaced even more coal and lignite, perhaps about 50% of last years generation ~75TWh.

    But it is what it is, and the chart trend lines make for very positive progress.

    Bit of an American theme for today's lecture, just sit down, grab a giant burger and a 64oz slurpy, and we'll get started:

    Two articles covering the same basic issue of how much energy the US uses (always remember that these figures are gross based on the FF extracted, not the net energy that can be usefully consumed), and the shift to RE capacity as we move forward:

    How Much Energy Does The US Consume & Where Does It Come From? — Pew Research

    I'd risk suggesting that the second chart is terrifying, but again, remember gross energy from FF's v's RE leccy, that RE generation is now winning, BEV's are winning, and heat pumps are growing in popularity. The solutions are better than what exists today, so a natural shift is inevitable ..... just need to ramp up that shift.


    Wind & Solar Power Will Dominate 2020 In US, Despite Trump

    Note that these are capacity figures not generation, but also remember that some of the net gas capacity increase will be displacing coal generation .......


    ....... speaking of coal closures, we have this article:

    Tri-State G&T To Boost Renewable Energy Goal To 50% By 2024
    Tri-State Generation & Transmission serves the needs of 43 electric cooperatives in 4 states. In all, it provides electricity for 1,000,000 customers located across 2,000 square miles of America. Last August, Tri -State’s new CEO, Duane Highley, announced his intention to move the company toward renewable energy and away from coal as soon as possible.
    On January 15, Highley’s emphasis on renewable energy became official policy for the Colorado-based company. According to the Denver Post, Tri-State intends to increase the amount of electricity it generates from renewable sources to 50% by 2024. Not so long ago, utility companies were talking about 50% renewables by 2050. But the stark price advantage renewables now have (after all, once a wind or solar farm is constructed, there are no fuel costs to pay), has upset the apple cart in the industry. 2024 is less than 4 years away. Things are starting to move quickly.
    Part of the plan is to build 8 new wind and solar installations that will provide enough electricity to power 850,000 homes. In addition, the company plans to add electric car chargers throughout its service area.

    It will also close the Escalante coal generating station in northwest New Mexico by the end of this year and shut down other coal plants in Craig and at the Colowyo Mine in northwest Colorado by 2030. One unit of the Craig facility was scheduled to continue operating until 2038 and another until 2044. The Escalante plant could have continued in operation until 2045. In addition, the company has dropped plans to build a new coal-powered facility in Holcomb, Kansas. “We’re committed to not adding any new coal generation in the Tri-State cooperative,” Highley said. It has not ruled out building new natural gas generating facilities to offset closure of several coal plants, however.
    Mark Dyson of the Rocky Mountain Institute said Tri-State’s new plan is consistent with a study his organization did in 2018 that mapped out how the utility could save $600 million through 2030 if it replaced coal facilities with wind and solar energy. “Overall, I’d say that what they announced today is consistent with our own analysis with how they can move forward with a lower-cost, clean-energy future,” Dyson said.
    In the end, the dramatic decline in the cost of renewables is upending traditional thinking in the utility industry — and not a moment too soon. Notice these changes are being driven by cost alone. Reducing emissions of greenhouse gases has little if anything to do with. What better argument for a comprehensive carbon fee could there be?

    Some numbers and breakdowns for RE deployments in 2019:

    Global clean power investment 'hits £282bn'
    Global investment in renewable energy capacity hit $282bn last year boosted by a string of offshore wind deals, according to BloombergNEF.

    The figure was up 1% from $280.2bn in 2018, thanks to a second busier half of the year.
    Falling capital costs in wind and solar meant that the two combined are likely to have seen around 180GW added last year, up some 20GW on 2018, BNEF found.
    The UK invested $5.3bn, down 40% and its lowest since 2007. Germany was down 30% at $4.4 bn, its lowest since 2004. The Netherlands was up 25% at $5.5bn, France was 3% higher at $4.4bn, and Ukraine 56% up at $3.4bn.

    Would there be enough pasture land in the world to house the amount of cattle that people eat, especially as more countries adopt the western diet?
    Besides the fact that the western diet is killing us, the short answer is yes. If, Permaculture systems are used. Don't forget, that calories are not the be all and end all. We need fat & protein. Animals and fish are the most protein, fat & nutrient dense. Further, the systems of agriculture dominant at present are degenerative, hence the "fertile crescent" now being mainly desert. Permaculture systems can make that land productive again.

    Perhaps we'd better put this conversation in anther thread?

    The trouble is animals don't produce protein, they obtain it from plants, either directly or indirectly. Further, this is an inefficient process - most of the protein in the plant material that the animal eats is lost rather than converted into animal protein.

    Now I'm not saying all agriculture is bad and should/will end, but using electricity to produce food from water and air has the potential to relieve a lot of the pressure on the natural world.

    It's definitely a fascinating prospect

    However economically mathematically easy to prove why it won't happen

    Food eg rice wheat corn = 30p /kg retail (eg flour in Tesco)
    So probably closer to 15p/kg wholesale
    Do the math and it's only about 3.2p/KWh

    Electricity costs much more than that
    Plus any electricity to hydrogen to bacteria to bigger food chains is going to have losses in every step and costs in every step

    So your starting point is off
    You're not going to be able to use 10p a unit electricity to make 3.2p a unit food

    However it might be more interesting in space where electricity could be as much as 10x cheaper or on Mars where traditional crops may be harder to do

    Germany to press renewables accelerator

    We now have a 'price' for the removal of coal/lignite and it's a biggy at $45bn, though that starts to look cheap compared to the ~£50bn in subsidies that HPC alone will be getting!

    Germany Will Pay $45 Billion To Rid Itself Of The Scourge Of Coal
    Germany has long depended on coal to generate electricity. Unlike the United States, which has turned its back on the commitments it made to the world community in Paris in 2015, Germany takes its promise to reduce carbon emissions seriously. This week, it hammered out an agreement that will see most coal generating stations within the country closed no later than 2038. The agreement calls for Germany to pay nearly $45 billion in compensation to various stakeholders over the next 18 years.
    CoalFreeDave is concerned that after 8 lignite facilities are closed by 2022, little further progress will be made until eleven lignite units are decommissioned between 2034 and 2038. There was 21 GW of lignite power in Germany in 2019. That will be reduced to 15 GW by the end of 2022. According to the agreement, lignite capacity will be cut to 8.8 GW between 2025 and 2029. Then no further cuts are planned until the last 11 lignite facilities are shuttered between 2034 and 2038.

    There is a review process built into the agreement that could move the end date forward by 3 years to 2035. The only hope for coal opponents is that the cost of renewables will continue to fall and drive lignite operators out of business before the new government mandates kick in.

    Strange one this, 'da yuff' lost the case, but the ruling confirmed that they have standing, it's just that the court simply can't demand and enforce the scale of change necessary - Too big to not fail?

    Youth activists lose appeal in landmark lawsuit against US over climate crisis
    Court confirms government’s contribution to the issue, but judges find they lack power to enforce climate policy decisions
    Nevertheless, the court found that the record “conclusively establishes that the federal government has long understood the risks of fossil fuel use and increasing carbon dioxide emissions” and “that the government’s contribution to climate change is not simply a result of inaction”.

    The court also found that the youth met the requirements for standing in the case and that some of the plaintiffs met the requirements for actual injury.
    Two of the three judges balked at the scope of change required to reverse climate breakdown, finding that halting certain programs would not halt the growth of carbon dioxide levels in the atmosphere or injuries to the plaintiffs.

    “Indeed, the plaintiffs’ experts make plain that reducing the global consequences of climate change demands much more than cessation of the government’s promotion of fossil fuels. Rather, these experts opine that such a result calls for no less than a fundamental transformation of this country’s energy system, if not that of the industrialized world … given the complexity and long-lasting nature of global climate change, the court would be required to supervise the government’s compliance with any suggested plan for many decades.”

    Put it this way, if regeneratively farmed they turn grass and some other plants into protein, fat, vitamins & minerals we can eat. Further, in many places they are making productive use of land that would not be suitable for vegetable crops.
