2017-06-12 Photovoltaic growth: reality versus projections of the IEA – the 2017 update

Auke Hoekstra

Update 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.

2007-07-03 Energy Criteria for Sustainable Energy Solutions

I was invited to give a presentation with this title at the European Sustainable Energy Forum 2007, in Lucerne, Switzerland.

2011-03-11 Fukushima - My Documents

On 2011-03-11, the Fukushima Daiichi nuclear power plant in Japan was damaged by a major earthquake and tsunami. The three operating reactors overheated, leading to hydrogen explosions and radioactive releases, which necessitated progressively wider evacuations of the populace. In the weeks that followed, it became clear that Reactors 1 to 3 and the spent fuel pools of Reactors 1 to 4 had the potential for far greater radioactive releases.

2016-09-15 Hinkley C nuclear go-ahead: May caves in to pressure from France and China

The French and the Chinese may be celebrating the UK's decision to press ahead with the Hinkley C 'nuclear white elephant', writes Oliver Tickell. But the deal is a disaster for the UK, committing us to overpriced power for decades to come, and to a dirty, dangerous, insecure dead end technology. Just one silver lining: major economic, legal and technical hurdles mean it still may never be built.

'The Government published a nuclear Consultation Document, THE ROLE OF NUCLEAR POWER IN A LOW CARBON UK ECONOMY, May 2007.

2005-04-22 Why Not Hydrogen ?

I created this presentation for the European Fuel Cell Forum, 2005, but did not give it.

2016-09-09 New tool can calculate renewable energy output anywhere in the world

Researchers have created an interactive web tool to estimate the amount of energy that could be generated by wind or solar farms at any location. The tool, called Renewables.ninja, aims to make the task of predicting renewable output easier for both academics and industry. The creators, from Imperial College London and ETH Zürich, have already used it to estimate current Europe-wide solar and wind output, and companies such as the German electrical supplier RWE are using it to test their own models of output.

2006-09-19 The Risks of Nuclear Power

As an engineer I became concerned that nuclear power posed unacceptable risks.

2004-07-30 Energy Solutions for 60% Carbon Reduction – Part II

This study was prompted by the Royal Commission on Environmental Pollution Report No. 22, "Energy - the Changing Climate", and by the U.K. Government Cabinet Office Performance and Innovation Unit (PIU) Energy Review. It adopts the target of a 60 % reduction in UK carbon emissions by 2050.

2016-09-07 Quantifying the Narrowing Net-energy Pathways to a Global Energy Transition

Sgouris Sgouridis et al

'Planning the appropriate renewable energy (RE) installation rate should balance two partially contradictory objectives: substituting fossil fuels fast enough to stave-off the worst consequences of climate change while maintaining a sufficient net energy flow to support the world’s economy. The upfront energy invested in constructing a RE infrastructure subtracts from the net energy available for societal energy needs, a fact typically neglected in energy projections. Modeling feasible energy transition pathways to provide different net energy levels we find that they are critically dependent on the fossil fuel emissions cap and phase-out profile and on the characteristic energy return on energy invested of the RE technologies. The easiest pathway requires installation of RE plants to accelerate from 0.12 TW p yr –1 in 2013 to peak between 7.3 and 11.6 TW p yr –1 in the late 2030s, for an early or a late fossil-fuel phase-out respectively, in order for emissions to stay within the recommended CO 2 budget’.

So the early fossil-fuel phase-out requires the installation of RE plants to accelerate by 7.3/0.12 = 61-fold and the late phase-out by 11.6/0.12 = 97-fold. Further delay would mean that there is no solution.

2021-09-29 Nuclear Power and the EU Taxonomy
Around September 2021, the European Commission considered the inclusion of nuclear power in the taxonomy for future investments in energy. This was based on a single report from the European Joint Research Centre, which still has close links with the nuclear industry and is widely perceived as playing a promoting role for nuclear energy within the European Union. The JRC Report ignored the report of the German Ethics Commission for a Safe Energy Supply of 2011, which had lead to Germany phasing out nuclear power by 2023. The European Commision also ignored 'Sustainability at risk, A critical analysis of the EU Joint Research Centre technical assessment of nuclear energy with respect to the "do no significant harm" criteria of the EU Taxonomy Regulation, of 2021-09 by Dr. Christoph Pistner, Dr. Matthias Englert and Dr. Ben Wealer, for the Heinrich Boell Foundation.
2023-06-06 Nuclear Power Has No Future
The UK government proposes to build nuclear power plants totalling 24 GW.This implies Hinkley Point C, Sizewell C and about six more of similar size.The Labour party proposes to include nuclear power in it’s new ‘green’ energy policy.Yet nuclear power has no future, as shown in this document of 3 pages with 52 references. The first section shows that nuclear fuel may be effectively exhausted before 2050, when the climate targets should be met. The second section shows that the costs of nuclear power have risen over time, and are now uncompetitive. So nuclear power must be replaced by sustainable and affordable options such as energy savings and renewables like wind, solar and storage. The third section shows that nuclear power conflicts with energy savings and renewables, so impairing the business case and deterring investment.So the UK should phase out nuclear power and join the rest of the world in deploying energy savings and renewables.Although this document is published after the latest Government and Labour Party proposals,I have published many earlier documents on nuclear power, dating from 2006-0-19. (See below).Most notably, my report on the Fukushima disaster was published on 2012-04-11, with copies sent to several MPs and Ministers.
2022-10-05 Nuclear Nonsense
The new UK government appears to support the previous government’s proposal of building new nuclear power plants. The Labour party proposes to include nuclear power in it’s new ‘green’ energy policy. However such nuclear proposals are nonsense, as shown in this 4-page due diligence assessment.
2022-08-12 Stopping Sizewell C and all nuclear power in favour of a rational energy policy
Among the last acts of the Johnson government was the approval of a new nuclear plant - Sizewell C. The claim was that it would increase energy security and reduce carbon emissions. But the invasion of Ukraine has underlined that all nuclear sites are targets, and reduce national security. Also nuclear power would be far more costly than energy savings and renewable energy sources such as wind and solar, with storage, and could not be generating electricity before 2030. They need uranium for fuel, yet almost half comes from Russia and Kazachkstan, so that the money and carbon costs would increase twice as fast. Moreover, they require huge amounts of energy to manufacture and build, so reducing energy security until construction is complete, and this energy repaid. Yet Hinkley Point C and Sizewell C are coastal sites, at risk from flooding by sea level rise and storm surge by 2100. As decommissioning and site clearance would take at least 50 years, they would need to be shutdown before 2050. Many reasons for stopping Sizewell C and all nuclear power are given in this collection of five documents.
2022-08-13 Nuclear Power And Weapons Are Killing Us
The Manhattan Project in the US covered every stage of the production of nuclear weapons. This included the mining and refining of uranium, enrichment to 80 to 90% U235 for uranium bombs, fuelling nuclear reactors with uranium to produce plutonium, and reprocessing the spent fuel to extract the plutonium for plutonium bombs. It was recognised from the beginning that these processes and plants would give rise to radioactive releases that would be harmful to the plant operators and the general public, yet they were never informed. This continues to the present day, when the nuclear weapon and power industry does everything in its power to deny and understate the many and extensive harms done to all living things. To this has been added the use of uranium in bunker-breaking bombs and tank-busting shells, that spread the dust so formed over their own forces, the enemy forces, and innocent bystanders, harming them all for generations to come. The human harms include many and extensive cancers, and also non-malignant diseases such as stillbirths, deformities and mental impairment and heart disease. With so much harm already done to humans that will take up to lifetimes to express, and so much nuclear debris laying in wait to harm even more humans, it is essential to identify every strategy and measure that can reduce the total harm.This document covers the first warnings of nuclear harms in the 1950s and - following studies beginning in the 1960s - five books of evidence by Dr Ernest Sternglass in 1981, Mr Harvey Wasserman et al in 1982, Dr John Gofman in 1990, Mr Paul Zimmerman in 2009, and Professor Chris Busby et al in 2010.

2021-06-09 The Futility of Fusion - A Dream Too Far
For the Presentation, Conclusions and a document with references, click on Read More. Nuclear fusion power on earth poses extreme technical challenges. One is the attainment of at least 100 million degrees C for long enough to produce net energy. Another is that any power plant fuelled with Deuterium and Tritium must 'breed' enough Tritium to sustain itself. Yet fusion power is futile because it cannot be deployed at a meaningful scale before 2050. This is the target date for Zero Carbon - hopefully limiting Global Warming to less than 2 C. So by this date all energy must be supplied from proven renewable sources such as Solar Photovoltaics, Wind Power, Hydro Power, sustainable Biomass and Solar and Deep Geothermal Heat.

2016-12-01 Energy Solutions for Sustainability
This note reflects Danish and German precedents on energy solutions, from which I have learnt the underlying principles.Humankind requires not energy but energy services such as illumination, movement and thermal comfort. Germany realisesthat it is not enough to set targets for reducing carbon emissions; policies, plans and actions are also required. It has adoptedthe ‘Energiewende’ energy transition plan for 80 to 95% carbon reduction by 2050. 1 Solutions for sustainable energy servicescan be determined by following a few fundamental principles and metrics, enumerated in this document.
