The Breakthrough Institute's paper "Historic Paths To Decarbonisation" examines the rate at which various contries have decarbonised their energy supplies, compared with the rate thought necessary to stabilise climate change. The paper looks particularly at Sweden and France's decarbonisation following the 1970s Oil Crisis, and Ireland and the UK.
Solar Power to Triple During Next Five Years JOHN ADDISON; Cityminded; 21 Jul 2015
- Global solar capacity is forecasted to triple from the 178 GW capacity at the end of 2014 to over 500 GW by 2020, equivalent of one thousand typical coal or nuclear power plants. Solar energy will be 540 GW by 2020 in the high estimate, and 396 in the low, according to the European Photovoltaic Industry Association (EPIA).

Nuclear energy and path dependence in Europe’s ‘Energy union’: coherence or continued divergence? Andrew Lawrence, Benjamin Sovacool & Andrew Stirling; Climate Policy; 1 Jul 2016
- Since its initial adoption, the EU’s 2020 Strategy – to reduce its greenhouse gas emissions by 20%, increase the share of renewable energy to at least 20% of consumption, and achieve energy savings of 20% or more by 2020 – has witnessed substantial albeit uneven progress. This article addresses the question of what role nuclear power generation has played, and can or should play in future, towards attaining the EU 2020 Strategy, particularly with reference to decreasing emissions and increasing renewables.
Being pro-nuclear does not undermine climate and energy goals Stephen Tindale, Suzanna Hinson; Climate Answers; 26 Aug 2016
A Response to Lawrence, Sovacool, and Stirling. Nicholas Thompson; blog; 12 Oct 2016
- A few months ago I read a paper, “Nuclear energy and path dependence in Europe’s ‘Energy union’: coherence or continued divergence?” and after reading it, I wasn’t sold. Their fundamental idea was that in countries which are looking to build nuclear or replace existing nuclear, emissions are not dropping as fast as emissions in countries which don’t have nuclear or are closing nuclear facilities, and that the changes in emissions were due to “path dependence”, meaning that once a country decides to go nuclear, they get stuck on that path.
- The reason I wasn’t sold was there were a lot of words (21 pages), and three pages of references, but only one table that had any real data. That table showed a number of EU countries, how much their emissions had changed from 2005 and 2012, and the share of renewables in 2013 for that country. The change in emissions was presented in terms of percent reduction, without any data on absolute reduction in emissions, or the starting emissions for that country, and the growth of renewable generation also was not presented.
- The data was also compared to 2005, which seemed odd considering the paper talked at length about the EU 2020 Strategy (which started in 2010, and uses 1990 as its baseline). It was also strange that in 2016, data from 2012 was being used instead of data from a more recent year.

Is Germany’s renewable power boom stalling? Megan Darby; Climate Home; 3 Jan 2017
- Germany’s power generation from renewable sources is flatlining, according to a leading solar research institute. Solar, wind, biomass and hydropower sources produced 186TWh in 2016, or 34% of net electricity supply, analysis from the Fraunhofer Institute shows – showing no increase from the previous year. That was partly down to the weather: sunshine hours were down 4% and wind 14% from 2015 levels, lead researcher Bruno Burger told Climate Home. A clampdown on subsidies also hit installations of solar panels, he said. “For wind, it was only weather conditions; for solar, it was weather and policy.” With nuclear and coal generation in decline, the big winner was natural gas, which surged more than 40% on cheaper supplies.

The 4th Largest Economy In The World Just Generated 90 Percent Of The Power It Needs From Renewables JEREMY DEATON; Climate Progress; 9 May 2016
- On Sunday, for a brief, shining moment, renewable power output in Germany reached 90 percent of the country’s total electricity demand. That’s a big deal. On May 8th, at 11 a.m. local time, the total output of German solar, wind, hydropower, and biomass reached 55 gigawatts (GW), just short of the 58 GW consumed by every light bulb, washing machine, water heater and personal computer humming away on Sunday morning. (It’s important to note that most likely, not all of that 55 GW could be used at the time it was generated due to system and grid limitations, but it’s still noteworthy that this quantity of power was produced.)

Myths about Danish Wind Power: Why 39% Wind Is Not Enough Taís Pinheiro; Worldwatch Institute Europe; 7 Feb 2015
- In the first week of January, the Danes celebrated the fact that 39% of total electricity consumed in Denmark in 2014 came from wind turbines. Data from the Danish Ministry of Climate, Energy and Building indicates that the amount of electricity consumed from wind power has experienced a significant increase from the 18.7% nearly a decade ago, to 32% in 2013 up to 39% today. Last year’s increase can be attributed to the decrease of energy consumption and the installation of over 100 new offshore windmills. The historical increase of wind power over the past decade is a result of massive investments in wind technology by the Danish industry since the 1970s. These investments resulted in the establishment of the first offshore wind farm in the world in 1991 off the Danish coast. In addition, Denmark has numerous wind turbines installed across the country, and Danish wind companies have spread their technology by installing over 90% of the world's offshore turbines. Glancing at these achievements, a few facts can be easily misinterpreted, such as the percentage of turbines in Denmark relative to the world, the real share of wind in the total energy production, and the necessary effort to reach 100% renewable energy.
Portugal runs for four days straight on renewable energy alone Arthur Neslen; Guardian; 18 May 2016
- Portugal kept its lights on with renewable energy alone for four consecutive days last week in a clean energy milestone revealed by data analysis of national energy network figures. Electricity consumption in the country was fully covered by solar, wind and hydro power in an extraordinary 107-hour run that lasted from 6.45am on Saturday 7 May until 5.45pm the following Wednesday, the analysis says.

This 100% was preceded by more than 70 percent of its electricity from renewable sources of energy during the first quarter of 2013, and 63% for all of 2014. Portugal stopped burning coal in 1994.
- According the the IEA, the main sources of Portugal’s energy is coming from biofuels and waste. Wind and hydropower and adding increasingly larger amounts, with geothermal and solar just starting to take off.

Did Portugal run for four days on renewables alone? Roger Andrews; Energy Matters; 23 May 2016
- Recently there has been much rejoicing in the green media that the entire country of Portugal succeeded in powering itself with 100% renewables for four straight days from May 7 through May 10, 2016. Here we look into the question of whether this is true (it is) and second the question of what caused it (the weather). Over the period in question Portugal was able to make maximum use of its hydro and wind capacity because of unusually heavy rains and strong winds, a combination of renewables-favorable weather conditions that has been described as “fantastic”, although the tourism industry may take a different view.

CO2 Emissions Variations in CCGTs Used to Balance Wind in Ireland Euan Mearns; Energy Matters; 15 Apr 2016
- The island of Ireland functions as a single electricity grid linked to the British mainland by two interconnectors with a combined capacity of 1 GW. The Republic of Ireland in the south has set a goal to have 40% of electricity generated from renewables, mainly onshore wind, by 2020. Variable intermittency will be balanced using frame type combined cycle gas turbines (CCGTs). As the level of wind penetration grows the CCGTs need to work harder ramping up and down to compensate for variable wind. This causes increased wear and tear on the CCGT plant and also significantly reduces the energy efficiency of the CCGTs raising their specific CO2 production. During 2014 and 2015, average wind penetration was 22%, the CCGTs produced 575 Kg of CO2 per MWh and the average fuel efficiency was 32% compared with a design specification of 55%.
French NIMBYs get wind turbines removed, shift focus back to nuclear Joanna Foster; RenewEconomy; 20 Nov 2013
- Earlier this month, judges in Montpellier, France ordered French energy company GDF Suez to take down 10 wind turbines near the city of Arras in Northern France. The decision comes after a six-year legal struggle between GDF and a local couple who claimed the 10 turbines, installed back in 2007, destroyed the character of their 17th century chateau. France is currently heavily dependent on nuclear. 58 nuclear reactors across France provide over 75 percent of the nation’s power mix. Nuclear reactors have long been the key to French energy independence. French President Francois Hollande has pledged to bring the country’s reliance on nuclear down to 50 percent by 2025, without lifting the country’s ban on fracking, in place since 2011.
France Burns Coal Like It's 1984 as Prices Jump on Atomic Woes Rachel Morison; Bloomberg; 18 Oct 2016
- France produced the most power from fossil fuels for September in 32 years to help meet demand as nuclear generation dropped. Output from coal and gas plants more than doubled as Paris-based Electricite de France SA was forced to keep reactors offline for inspections. French month-ahead power prices have risen to near the highest since 2009. EDF’s reactors produced 26.6 terawatt-hours of electricity in September, the least since August 1998, prompting “heavy use” of stations burning coal and gas in a trend that has been increasing since April, according to a report by French grid operator Reseau de transport d’electricite. Thermal power generation was 4,132 gigawatt-hours, or 11 percent of the total. France has seven fewer reactors available than at the same time last year after EDF announced it needed more time to carry out inspections to rule out potential anomalies on steam generators at 18 of its 58 units ordered by the nation’s nuclear regulator. EDF cut its nuclear output targets for the year on Sept. 21 after the safety checks were taking longer than expected. Six reactors are due to return this week.
- The Nuclear Safety Authority (ASN) has asked nuclear power utility EDF to carry out additional inspections at Fessenheim 1,Tricastin 2 and 4, Gravelines 4 and Civaux 1 reactors, according to a press release. “The performance of these inspections will require shutdown of the reactors concerned,” ASN added. The watchdog wants to check “certain channel heads of the steam generators on five of its reactors, in which the steel is affected by a high carbon concentration.” According to ASN’s analysis, “certain channel heads of the steam generators … contain a significant carbon concentration zone which could lead to lower than expected mechanical properties.” The watchdog said that it doesn’t want to wait “for the scheduled refueling outage of these reactors” and thus demands safety checks “within three months.” According to the Local, this abnormality could lead to failures in mechanical properties and even to leaks or explosions. The five reactors under scrutiny are among 18 at which ASN found abnormalities in June. Of the 18 reactors ASN says that six could be restarted after inspection. Seven others (Bugey 4, Civaux 2, Dampierre 3, Gravelines 2, Saint-Laurent-des-Eaux B1 and Tricastin 1 and 3) are being inspected and awaiting reboot.
Energy in Sweden wikipedia
Energy Use In Sweden sweden.se
- Sweden has invested heavily in the search for alternative energy sources ever since the oil crisis of the early 1970s. In 1970, oil accounted for more than 75 per cent of Swedish energy supplies; today, the figure is around 20 per cent, chiefly due to the declining use of oil for residential heating.
- Few countries consume more energy per capita than Sweden, yet Swedish carbon emissions are low compared with those of other countries. According to the latest statistics from the International Energy Agency (IEA), the average Swede releases 4.25 tonnes of carbon dioxide (CO₂) per year into the atmosphere, compared with the EU average of 6.91 tonnes and the US average of 16.15 tonnes. Sweden has found a way to reduce emissions while the economy is growing.
- The reason for this low emission rate is that 83 per cent of electricity production in Sweden comes from nuclear and hydroelectric power. Cogeneration from combined heat and power (CHP) plants accounts for 10 per cent of the electricity output in Sweden, and these are mainly powered by biofuels. About 7 per cent of the electricity comes from wind power.
How to decarbonize? Look to Sweden Raymond Pierrehumbert; Bulletin of the Atomic Scientists - Special Issue: Young People and Existential Threat; Volume 72, Issue 2, 2016
- Bringing global warming to a halt requires that worldwide net emissions of carbon dioxide be brought to essentially zero; the sooner this occurs, the less warming our descendants for the next 1000 years and more will need to adapt to. The widespread fear that the actions needed to bring this about conflict with economic growth is a major impediment to efforts to protect the climate. But much of this fear is pointless, and the magnitude of the task – while great – is no greater than the challenges that human ingenuity has surmounted in the past. To light the way forward, we need to examine success stories where nations have greatly reduced their carbon dioxide emissions while simultaneously maintaining vigorous growth in their standard of living; a prime example is Sweden. Through a combination of sensible government infrastructure policies and free-market incentives, Sweden has managed to successfully decarbonize, cutting its per capita emissions by a factor of 3 since the 1970s, while doubling its per capita income and providing a wide range of social benefits. This has all been accomplished within a vigorous capitalistic framework that in many ways better embodies free-market principles than the US economy. Consequently, the Swedish experience shows that solving global warming does not require us to “tear down capitalism.” The world just needs to be a bit more like Sweden.
The looming Nordic energy crisis Rauli Partanen; energy post; 10 Mar 2016
- Sweden is faced with the possible shutdown of its entire nuclear generating capacity. This could result in grid instability, price hikes and much higher greenhouse gas emissions, writes Rauli Partanen, an independent analyst and author on energy and the environment. Partanen calls on policymakers to take action to avoid a Swedish nuclear phaseout.
- Nuclear power in Sweden has become uneconomical. Wholesale prices of electricity in Sweden have been much lower than the breakeven price for nuclear generation. Electricity has been sold at a record low price of €20 per megawatt hour (MWh), while the cost of generating nuclear power has been in the same ballpark, or even slightly higher. In addition, the Swedish government has set a tax on nuclear power, which has been steadily rising. After the latest hike, it amounts to about a third of the wholesale price, roughly €7 per MWh.
- Sweden’s lobbying organization for wind power has written that it thinks Swedish nuclear can be replaced by building many times more wind power than Sweden has now, and by dealing with peak hours and low winds by building gas turbines. This amount of wind would be hugely uneconomical to build. The gas turbines could also cost billions of euros, and they would be running only a few hours during the year, making them monumentally bad investments. At current market conditions, nobody would build either of these without very generous subsidies from the government.

Boost to nuclear energy as Sweden agrees to build more reactors Richard Milne, Nordic Correspondent; FT; 10 Jun 2016
- Sweden aims to produce all of its power from renewable sources by 2040 but in the meantime will build new nuclear plants to replace old ones being phased out, according to an agreement between government and opposition parties on Friday. ... Friday’s agreement does not specify which technology the plants should use. ... Permission may be granted to replace existing reactors at the same sites with a maximum of 10 to be built in all, according to the deal between the governing Social Democrats and Greens as well as the opposition Moderates, Centre party and Christian Democrats. ... Politicians emphasised that the goal of 100 per cent renewable energy by 2040 did not mean that nuclear plants would be closed then. “This is a goal, not a cut-off date that would prohibit nuclear power, and it does not mean either the end a closure of nuclear power,” the agreement stated. Ibrahim Baylan, the energy minister, said: “This is a traditional Swedish compromise.”
Renewable California Roger Andrews; Energy Matters; 30 June 2016
- California is considered by many to be a world leader in the transition to renewable energy. But how much progress is it really making? This post looks into this question and finds that California has indeed significantly increased the percentage of renewable energy in its in-state generation mix – or at least would have done were it not for the impact of the recent drought on hydro output – but that it has made no progress towards increasing its zero-carbon generation, which because of the shutdown of the San Onofre nuclear plant remains lower than it was in 2002 even when the impact of the drought is factored out. This result underscores the importance of nuclear as a key ingredient in reducing CO2 emissions, a fact which seems to have escaped California’s attention.

China is on an epic solar power binge Richard Martin; MIT Technology Review 22 Mar 2016
- In 2015, the country added more than 15 gigawatts of new solar capacity, surpassing Germany as the world’s largest solar power market. China now has 43.2 gigawatts of solar capacity, compared with38.4 gigawatts in Germany and 27.8 in the United States. According to new projections, it seems that trend is going to continue. Under its 13th Five Year Plan, China will nearly triple solar capacity by 2020, adding 15 to 20 gigawatts of solar capacity each year for the next five years, according to Nur Bekri, director of the National Energy Administration. That will bring the country’s installed solar power to more than 140 gigawatts. To put that in context, world solar capacity topped 200 gigawatts last year and is expected to reach 321 gigawatts by the end of 2016.

China to plow $361 billion into renewable fuel by 2020 Reuters; 5 Jan 2017
- China will plow 2.5 trillion yuan ($361 billion) into renewable power generation by 2020, the country's energy agency said on Thursday, as the world's largest energy market continues to shift away from dirty coal power towards cleaner fuels.
- National Energy Administration (NEA) said in a blueprint document that lays out its plan to develop the nation's energy sector during the five-year 2016 to 2020 period.
- The NEA said installed renewable power capacity including wind, hydro, solar and nuclear power will contribute to about half of new electricity generation by 2020.
- Last month, the National Development and Reform Commission (NDRC), the country's economic planner, said in its own five-year plan, that solar power will receive 1 trillion yuan of spending, as the country seeks to boost capacity by five times. That's equivalent to about 1,000 major solar power plants, according to experts' estimates.
- Some 700 billion yuan will go towards wind farms, 500 billion to hydro power with tidal and geothermal getting the rest, the NDRC said.
- Illustrating the enormity of the challenge, the NEA repeated on Thursday that renewables will still only account for just 15 percent of overall energy consumption by 2020, equivalent to 580 million tonnes of coal. More than half of the nation's installed power capacity will still be fueled by coal over the same period.
- 2.5 trillion yuan total - 1 trillion solar == 1.5 trillion
- 1,500 billion - 700 billion wind - 500 billion hydro == 300 billion tidal + geothermal

The Australian town that wants to get off the grid BBC News; 23 Aug 2016
- The 300 residents of Tyalgum, set among the rolling hills near the Queensland-New South Wales border, are fond of saying their town is "beautiful 24-7". Soon, if all goes to plan, this little town in a region famed for its alternative lifestyle could be the first place in Australia to get off the electricity grid and keep the lights on 24-7 using 100% renewable energy. The idea was hatched in September 2014 by local entrepreneur Andrew Price, a 10-year veteran of the renewable energy industry who runs the company Australian Radio Towers.
- Then there's Tyalgum's economic makeup - the town is reliant on tourism and there are few stable jobs, so electricity bills hit locals hard. According to Mr Price, the 300 people of Tyalgum collectively spend A$700,000 (£406,000, $534,000) a year on electricity, with 55% of that going to maintain the poles and wires. The project to take the town off the grid has attracted A$15,000 in government funding so far. Solar energy systems will be granted to property owners across the town through a lottery. They will then pay a portion of the money they save on electricity into a fund which will be used to install systems on the other 120-odd homes in town. Building the infrastructure needed to take the entire village off the grid is expected to cost A$7m.
The Battery of the Gaps ACTINIDEAGE; 1 Sep 2016
Approaching 62 hours becalmed on the mainland – what would this mean for battery storage? Paul McArdle; WattClarity; 30 Mar 2015
- This morning I noted (and tweeted) that there was virtually no wind production collectively coming from all wind farms across the mainland. This situation has continued through till this afternoon, which means that for the past 15 hours total wind production NEM-wide has been below 400MW, and as low as 200MW (with most of what is being produced in this spell coming from Tasmania). What’s more, the total wind production has been below approx 550MW since midnight heading into Saturday morning.
Why I waited to comment on the SA blackout: reflections on preliminary findings Ben Heard; DecarboniseSA; 6 Oct 2016
- South Australia was rolling along merrily and in good shape when warnings of extreme weather came in. About 24 hours later when the extreme whether struck, we were asking for about 1800 MWe of power from our grid, which is connected to the much larger state of Victoria via two interconnectors. About half that power was coming from wind at the time, much of which is based in the north of the state, roughly 20% was coming from gas in South Australia and the balance (30%) was coming through the interconnectors (which is coal, basically).
- A section of transmission line south of Port Augusta, near Melrose, was hit with extreme winds, quite possibly tornadoes, and wrecked. Eventually three lines went out of service and six wind farms reduced output. This sudden imbalance of supply/demand was felt as a major drop of frequency. In response, the grid started clamouring for frequency from the rest of the system to stay in operational range (49.5-50.5 Hz). So, virtually instantaneously, it was pulling in supply from other synchronous generators who felt the perturbation in the system, including across the interconnector.
- At first it was ok then…more supply gone…more frequency being lost…more clamouring for stability.
- This need for more stability was felt as a demand for 900 MWe through an interconnector designed for 600 MWe. That’s too much. To stop potential for damage, the interconnector cut us off, and it was lights out for South Australia.

- A world-leading project that will combine solar PV, wind energy and battery storage, and which could ultimately be one of the biggest power stations in Queensland, has received financial support from the Australian Renewable Energy Agency. kennedy wind mapARENA announced on Friday that the Kennedy Energy Park — being built by Australia’s Windlab and Japan’s Eurus Energy near Hughenden in north Queensland — will receive $18 million in “recoupable” grants to help fund the $120 million first stage of the project. That first stage will comprise 19.2 MW of solar PV, 21.6 MW of wind and 2 MW/4 MWh of battery storage. But over time, the project may expand to 600 MW of solar PV and 600 MW of wind energy, and more battery storage, and provide the equivalent of “baseload” power to north Queensland, enough to meet one fifth of Australia’s renewable energy target. It would also account for a sizeable piece of the new wind and solar projects required to meet the Queensland government’s own 50 per cent renewable energy target by 2030, which was outlined earlier this week.
Small 100% renewables projects: Tasmania, El Hierro, Ta'u etc
The Myth of Sustainable Power from Renewables Institute for Energy Research; 17 mar 2016
- Two islands—one off Spain and one off Australia—are using renewable energy to supply power to their homes and industries in the hopes that they can be free of fossil fuels. Tasmania, an island off the south coast of Australia, was virtually 100 percent renewable, but had to bring in diesel generators to get it through an energy crisis. El Hierro, one of the Canary Islands off of Spain, had been 100 percent diesel-powered, but turned to a hybrid wind/pumped storage hydroelectric system to replace the diesel generators, only to find that the island is still dependent on them. In each case, the cost has been huge, and should be cautionary tales to policymakers who want to tinker with the electricity systems we depend upon.
Islands Trying To Use 100% Green Energy Failed, Went Back To Diesel ANDREW FOLLETT, Energy and Environmental Reporter; Daily Caller; 18 Mar 2016
- The islands of Tasmania and El Hierro tried to power their economies with 100 percent green energy, but both islands eventually went back to diesel generators after suffering reliability problems and soaring energy costs.

King Island Renewable Energy Integration Project Hydro Tasmania
- Nearly 100 years ago Hydro Tasmania embarked on a clean energy journey, becoming one of Australia’s leaders in renewable energy development. Today, we continue our proud history of clean energy with the King Island Renewable Energy Integration Project (KIREIP).
Solar power on the island of Ta’u, a preliminary appraisal Roger Andrews; Energy Matters; 15 Dec 2016
- A 1,400kW(p) solar PV array backed up by 6,000kWh of battery storage and a smart grid has been installed on the island of Ta’u in American Samoa. It’s reported that this system already allows Ta’u to obtain 100% of its electricity from renewable sources for 100% of the time, and this brief review suggests that it will in fact be capable of delivering 100% electricity for almost 100% of the time if and when it reaches full operation. However, the operator Solar Power (recently acquired by Tesla) foresees potential problems in integrating 100% solar energy with the grid and plans on a “phased approach” to identify and resolve them. Consequently the system will not supply 24/365 renewable electricity immediately, and its ability to deliver it in the future will be dependent on whether a grid fed by 100% solar energy can be made to work.
This Country Isn’t Just Carbon Neutral … It’s Carbon Negative Cole Mellino; EcoWatch; 19 Mar 2016
- Bhutan is often overlooked by the international community. The small nation lies deep within the Himalayas between China and India, two of the most populated countries in the world. But the country of about 750,000 people has set some impressive environmental benchmarks. As we’ve written about in the past, Bhutan is not merely carbon neutral, it’s also a carbon sink—making it one of the few countries in the world to have negative carbon emissions. This means the country’s carbon sinks, such as its forests, absorb more carbon dioxide each year than its sources of pollution, such as factories, emit. “According to recent figures, the country emits around 1.5 million tonnes of carbon annually, while its forests absorb over 6 million tonnes,” Proudly Carbon Neutral said.
