I found this presentation by Matthew Stocks et al and asked the permission of Professor Andrew Blakers to extend it with a section on the potential in the UK. He agreed, and Dr Matthew Stocks kindly provided extracts for the UK.
This shows that there are 195 sites in the UK, with a total potential capacity of 6047 GWh.As the requirement for 100% renewable electricity is only about 1400 GWh, it would be possible to select the best, near to existing grid power lines, and with the greatest height difference between the upper and lower reservoirs.
However, the UK has several interconnectors to neighbouring countries, some with time differences. These should allow 100% renewable electricity to be achieved with somewhat less pumped storage in the UK and the neighbouring countries.
The Fukushima disaster was aggravated by the personnel being responsible for multiple reactors under emergency conditions.
There had been no testing or drills of Station Blackouts and Loss of Cooling Accidents in the 40 years since the reactors were built.
Once reactor meltdowns and radioactive releases had occurred, they had no means of mapping the fallout to guide evacuation.
The later Abe government coerced ‘voluntary’ evacuees to return by stopping their housing subsidies after only six years. Many still resist returning, despite the hardships.
The Abe government also sought to restart the 39 remaining operable nuclear power plants, but succeeded with only a few. Nuclear power is still strongly resisted by most Japanese.
Joshua S HillA new report commissioned by the Crown Estate Scotland has found that not only does floating offshore wind have an important role to play in the UK’s plans to generate 50 gigawatts (GW) from offshore wind by 2050 but that it could support up to 17,000 jobs and provide £33.6 billion in added value.
Auke HoekstraUpdate for 2017: the IEA is once again predicting the solar industry will stop growing. As you can see in the updated graph, yearly additions are still increasing rapidly but again the prediction of the IEA is flat. Fortunately many sources are noticing this or using “my” method for showing how far the IEA is off the mark. Examples here, here, here, here, here, here, here, here, here, here and here. I hope the criticism will grow exponentially until the IEA learns.
Akshat RathiIn a report to be published later today, the European Court of Auditors will say that the EU spent more than €424 million ($486 million) over the past decade decade fruitlessly trying to establish carbon-capture technology. The EU considers the technology crucial to hit its climate goals, which will require the union’s member states to reach net-zero emissions within decades.
Urgent changes needed to cut risk of extreme heat, drought, floods and poverty, says IPCC
The world’s leading climate scientists have warned there is only a dozen years for global warming to be kept to a maximum of 1.5C, beyond which even half a degree will significantly worsen the risks of drought, floods, extreme heat and poverty for hundreds of millions of people.The authors of the landmark report by the UN Intergovernmental Panel on Climate Change (IPCC) released on Monday say urgent and unprecedented changes are needed to reach the target, which they say is affordable and feasible although it lies at the most ambitious end of the Paris agreement pledge to keep temperatures between 1.5C and 2C.The half-degree difference could also prevent corals from being completely eradicated and ease pressure on the Arctic, according to the 1.5C study, which was launched after approval at a final plenary of all 195 countries in Incheon in South Korea that saw delegates hugging one another, with some in tears.“It’s a line in the sand and what it says to our species is that this is the moment and we must act now,” said Debra Roberts, a co-chair of the working group on impacts. “This is the largest clarion bell from the science community and I hope it mobilises people and dents the mood of complacency.”
Jesper BerggreenAs I noted in earlier posts about the Danish government’s plan to phase out diesel and gas cars by 2030, a full plan for emission reductions over the next 12 years would be revealed this week. And indeed it was. The plan is called “Together for a greener future.” This plan is the second of two parts. The first part was the “Energy — for a green Denmark” which was boosted considerably in the rare consensus by all parties in parliament in July where for instance the plans for adding 8 gigawatts (GW) of offshore wind power was tripled to 24 GW.While Denmark is a pretty insignificant country in the scale of things, it was actually quite an achievement to reach bipartisan agreements on upping the game as opposed to the more common dismantling. I remember that Thomas L. Friedman played with an idea in his 2008 book “Hot, Flat and Crowded” where he imagined the US being China for just one day and how that could make so many rules come into effect, fast. Well, the current president is trying to do just that, but unfortunately he has yet to push rules on avoiding catastrophic climate change. My point is that it was very refreshing to witness this consensus in July, and it should serve as an example to countries with much bigger impact.
Josh GabbatissNew fuels and accompanying hikes in ticket prices will be essential to clean up air travel and avoid the worst effects of climate change, according to a new report.Aviation is responsible for 5 per cent of global warming, and it is on track to power through a quarter of the planet’s annual carbon budget by 2050.Despite some fledgling efforts to develop electric aircraft for short-haul flights, air travel is proving one of the most difficult sectors to decarbonise.In its analysis, European green transport group Transport and Environment (T&E) found that replacing fossil fuels in planes with “electrofuels” is the “only technically viable solution that would allow aviation to exist in a world that avoids catastrophic climate change”.
This will present a challenge to consumers as well as the industry, as the expense of these fuels means the cost of a plane ticket is projected to rise 58 per cent if they replace kerosene in all aircraft.
“The good news is that radically cleaner aviation is possible even with today’s technology,” said Andrew Murphy, aviation manager at T&E.“Getting to zero starts with properly pricing flying and progressively increasing the use of sustainable synthetic fuels.“There is a cost to this, but in light of how cheap subsidised air travel has become, and the incalculable cost of runaway climate change, it’s a price worth paying.”
Companies hoping to build new windfarms, solar plants and tidal lagoons, have been dealt a blow after the government said there would be no new subsidies for clean power projects until 2025 at the earliest.The Treasury said it had taken the decision to “protect” consumers, because households and businesses were facing an annual cost of about £9bn on their energy bills to pay for wind, solar and nuclear subsidies to which it had already committed.The revelation that there will be no more money for projects before 2025 could dash hopes for pioneering projects such as the proposed £1.3bn tidal lagoon in Swansea, which has a mooted launch date of 2022.In a Treasury document on carbon levies published on Wednesday, officials said: “On the basis of the current forecast, there will be no new low-carbon electricity levies until 2025.
Environmental groups criticised the Treasury move. The WWF said it was a huge disappointment, while Greenpeace claimed Wednesday’s budget was one of the least green ever.Business groups also reacted with dismay. The pro-environment Aldersgate Group, whose members include BT, Ikea and Marks & Spencer, said the lack of clarity on low-carbon power investments was disappointing.James Court, head of policy at the Renewable Energy Association, said: “The UK government seem to be turning their back on renewables by announcing no new support for projects post-2020 and a freeze on carbon taxes.”
