Germany Urged To Return To Nuclear As Wind And Solar Fail, Prices Soar

by P. Gosselin, Nov 25, 2024 in ClimateChangeDispatch

Germany phased out its entire fleet of nuclear reactors over the past years and hoped to rely on renewable energies, claiming they were cheaper and cleaner. [emphasis, links added]

However, the transition has not gone smoothly as grid revamping has not kept up and prices for wind and solar power have made German electricity among the most expensive worldwide.

At the UN Climate Change Conference in Baku, Rafael Grossi, head of the International Atomic Energy Agency (IAEA), has warned that: “Germany can no longer turn its back on nuclear power and that a reorientation of energy policy is necessary. The government must reopen the debate on nuclear power.”

“Countries that have nuclear energy want more of it. And many that don’t have any want it,”  said Grossi.

“The timing of his comments is no coincidence. Germany’s economy is suffering from energy problems while the government is consumed with internal disputes,” comments Blackout News.

“The political focus has recently been on the disputes within the coalition government, while the electricity market has continued to show new weaknesses.”

Blackout News describes how the prices of electricity “exploded” in early November during a period of calm winds and no sunshine.

This forced Germany to fall back on gas and coal (energy sources that the government is currently working to phase out as well).

“Fossil fuels supplied 71% of Germany’s electricity at the beginning of November – a figure that has not been reached for over a decade.”

The Cost of Net Zero Electrification of the U.S.A.

by K.G. Gregory, Aug 23, 2022 in FriendsOfScience

Executive Summary
Many governments have made promises to reduce greenhouse gas emissions by replacing fossil fuels with solar and wind generated electricity and to electrify the economy. A report by Thomas Tanton estimates a capital cost of US$36.4 trillion for the U.S.A. economy to meet net zero emissions using wind and solar power. This study identifies several errors in the Tanton report and provides new capital cost estimates using 2019 and 2020 hourly electricity generation data rather than using annual average conditions as was done in the Tanton report. This study finds that the battery costs for replacing all current fossil fuel fired electricity with wind and solar generated electricity, using 2020 electricity data, is 111 times that estimated by the Tanton report. The total capital cost of electrification is herein estimated, using 2020 data, at US$290 trillion, or 13.5 times the U.S.A. 2019 gross domestic product. Overbuilding the solar plus wind capacity by 18% reduces overall costs by 17% by reducing battery storage costs. Allowing fossil fuels with carbon capture and storage to provide 60% of the electricity demand dramatically reduces the total costs from US$290 trillion to US$20.5 trillion, which is a reduction of 92.9%. Battery storage costs are highly dependent on the year’s weather and the seasonal shape of electricity demand.

Green Energy: German Electricity Prices Skyrocket To Record Highs

by P. Gosselin & H. Douglas, Jan 27, 2020 in ClimateChangeDispatch

For a long time, electricity prices have known only one direction: upwards! Ever faster, ever more clearly.

Now the shock for many families: The Federal Government has presented official figures in an answer to an inquiry from the FDP Free Democrats parliamentary group in the Bundestag and announced the true extent of the electricity price increase.

320 euros extra annually per household

In the past ten years, the price of electricity for households and industry has risen by a third.

According to the Augsburger Allgemeine, which quotes from the paper, the price of electricity rose by 35 percent between 2009 and 2019.

For a typical household with 4,000 kWh per year, this means 320 euros in additional costs for electricity alone.

This is even more than the various comparison websites had previously calculated.

La transition électrique européenne, une impasse?

by J.P. Schaeken Willemaers, 29 mars 2019 in ScienceClimatEnergie

La transition énergétique est abondamment traitée dans les médias, souvent de manière univoque (ce que d’aucuns appellent le débat confisqué) en ignorant les conséquences socio-économiques. Dans ce papier, nous nous limiterons à sa composante électrique.
Rappelons tout d’abord que la finalité première d’un système électrique est d’assurer l’adéquation entre la production et la consommation d’électricité.


Il va de soi, quoique ce ne soit pas évident pour tout le monde, qu’il faut anticiper les adaptations nécessaires du système avant de procéder à la mise en œuvre du changement. Dans ce processus, l’analyse de l’impact sur la transmission et la distribution d’électricité et sur la continuité des services ainsi que la réalisation des travaux correspondants requis, sont prioritaires. Or aucun gouvernement ayant décidé de réduire drastiquement les émissions de gaz à effet de serre (GES), ne s’est soucié des conséquences de leurs décisions. Ceci explique les déboires des pays qui se sont précipités dans une stratégie de pénétration accélérée de production d’électricité renouvelable intermittente.

The Belgian electricity industry in chaos

by Prof. Samuel Furfari, January 7, 2019 in EuropeanScientist

Belgium’s electricity supply has become a serious problem. Without investment in new generation capacity, the security of electricity supply will deteriorate in the next few years. However, the country’s situation does not lend itself to optimism on this topic. Belgium is not a straightforward country. Its institutional structure can only be described as one of […] The post The Belgian electricity industry in chaos (https://www.europeanscientist.com/en/features/the-belgian-electricity-industry-in-chaos/) appeared first on European Scientist (https://www.europeanscientist.com/en)

L’électricité intermittente. Une réalité et un prix.

by prof. Samuel Furfari, 21 août 2018 in ScienceClimatEnergie

Il ne se passe pas un jour sans que surgisse sur les réseaux sociaux ou dans les médias une discussion sur le prix de l’électricité. Pour les uns, le prix de l’électricité produite par les énergies renouvelables est bas et pour les autres au contraire il est élevé. Qui a raison ?

Il faut examiner l’ensemble de la filière de la génération d’électricité pour pouvoir juger et non pas comme on le fait trop souvent se cantonner à un seul aspect. Nous allons donc procéder étape par étape, de manière à présenter de manière objective ce qu’il en est. Nous allons d’abord constater que la génération d’électricité à partir d’énergies renouvelables est déjà une forte réalité et qu’elle est en croissance. Nous allons ensuite observer qu’il est crucial d’équilibrer constamment la génération d’électricité et sa consommation et que cela ne peut se faire que par l’intermédiaire d’un réseau. Nous passerons ensuite au caractère intermittent de certaines énergies renouvelables et verrons quelles en sont les conséquences pour enfin pouvoir aborder la réalité des prix aux consommateurs. Dans la dernière partie nous allons parler du prix de l’électricité que nous payons en tant que consommateur et qui n’est pas bien entendu le coût de production.

Le but de cet article est qu’à travers cette démarche pédagogique le lecteur puisse se faire sa propre opinion sur la question du prix de l’électricité d’origine renouvelable.

Evaluation du coût de blackout dans l’Union Européenne

by Ernest Mund, 13 aoüt 2018, in ScienceClimatEnergie

La fourniture d’électricité est essentielle au développement économique d’une nation et à son harmonie politique et sociale. Les profondes mutations subies actuellement par le système électrique dans lequel la part des énergies renouvelables intermittentes ne cesse d’augmenter, présentent des risques pour cette fourniture. Il importe d’en assurer la sécurité. Evaluer le coût d’un blackout est donc un élément d’information essentiel, qui devrait être pris en compte dans toute décision future d’investissement en matière de génération de puissance.

A question that gives pause: If Solar And Wind Are So Cheap, Why Are They Making Electricity So Expensive?

by M. Shellenberger, President, Env. Progr., May 16, 2018  in WUWT

Over the last year, the media have published story after story after story about the declining price of solar panels and wind turbines.

People who read these stories are understandably left with the impression that the more solar and wind energy we produce, the lower electricity prices will become.

And yet that’s not what’s happening. In fact, it’s the opposite.

Between 2009 and 2017, the price of solar panels per watt declined by 75 percent while the price of wind turbines per watt declined by 50 percent.

And yet — during the same period — the price of electricity in places that deployed significant quantities of renewables increased dramatically.

Electricity prices increased by:

Countries Around Middle East Are Adding 44GW Of Coal Power Over Next Decade

by Paul Homewood, May 15, 2018 in NotaLotofPeopleKnowThat

From the US EIA:

Egypt, Oman, Iran, Jordan, and the United Arab Emirates (UAE) have no current coal-fired electricity generation, but they each plan to build coal capacity in the near future. New coal capacity is currently under construction in the UAE, Iran, and Jordan. In addition, Egypt and Oman have announced plans for new coal-fired generators.

In the UAE, new coal-fired capacity will come from Dubai’s Hassyan Project. The project consists of 3.6 GW of ultra-supercritical generating capacity, 2.4 GW of which is currently under construction and expected to become operational between 2020 and 2022. Another 1.2 GW was announced for a total of 6 units (with an average size of 600 megawatts (MW) expected to come online in 2023. The $3.4 billion project is sponsored by several investors, including Chinese and domestic banks.
