Some relevant quotes from the IEA’s Global Energy Review 2021

Some relevant quotes from the IEA’s Global Energy Review 2021

  • “A rise in CO2 emissions of almost 5% in 2021 compared to 2020.”
  • “Global energy demand is set to increase by 4.6% in 2021, more than offsetting the 4% contraction in 2020 and pushing demand 0.5% above 2019 levels.”
  • “Demand for renewables grew by 3% in 2020 and is set to increase across all key sectors – power, heating, industry and transport – in 2021. The power sector leads the way, with its demand for renewables on course to expand by more than 8% in 2021.”
  • “Solar PV and wind are expected to contribute two-thirds of renewables’ growth.”

Food for thought when reading the latest message from the UN Secretary-General, António Guterres, made at the opening of the recent 2-day Leaders’ Summit on Climate, who called on leaders everywhere to take urgent climate action:  “Mother Nature is not waiting”, he said. “We need a green planet — but the world is on red alert.” Click here for more details.

IEA-COP26 Net Zero Summit on March 31, 2021

IEA-COP26 Net Zero Summit on March 31, 2021

We recommend readers to refer to the summary and video of the IEA, by clicking attached link.

The Summit is an important event on the road to COP26 in Glasgow in November 2021. It brought together decisionmakers and representatives of more than 40 countries covering more than 80% of global GDP, population and emissions. Focus was on the critical need for international collaboration and policy implementation to accelerate clean energy transitions. On May 18, the IEA will publish a wide-ranging roadmap for the global energy sector to reach net-zero emissions by 2050. Good to continue monitoring these important developments.

Role of nuclear energy in the energy transition

Role of nuclear energy in the energy transition

We read with interest a recent article in the Dutch newspaper FD, in which prominent figures of the political party D66 advise the next Dutch government to seriously consider a role for nuclear energy from 2030. Our advice is to do this from a European perspective.

We would therefore like to recommend the politicians and readers of this website to also read the 2010 study by the European Climate Foundation (ECF). We have written about this before in previous blogs, but we would like to make reference to the Roadmap 2050 website again;  The various reports (Roadmap 2050 (click here), Power Perspective 2030 (click here)) also clearly describe the role of nuclear energy. We understand the concerns and questions about how to deal with radioactive waste, but we believe that responsible solutions are (will be) available.

Netherlands: discussion about phasing out solar panel netting scheme (“Salderingsregeling”)

Netherlands: discussion about phasing out solar panel netting scheme (“Salderingsregeling”)

The Dutch House of Representatives (“Tweede Kamer”) recently declared the bill to phase out the netting scheme for solar panels definitively controversial. The law will only be discussed in the House of Representatives after the upcoming national elections on March 17, 2021.

This development creates uncertainty for individual households and companies. On the other hand, people know that solar energy must be fully used. As part of a necessary energy transition and also necessary to achieve the Dutch climate goals. We can therefore assume that it will remain interesting for households and companies to invest in solar energy systems.

TenneT report: Monitoring security of supply of electricity in the Netherlands

TenneT report: Monitoring security of supply of electricity in the Netherlands

Security of supply of electricity is not an issue in the short term in the Netherlands. In the context of the (hopefully) growing energy transition and the greater dependency on generated renewable energy (wind and solar), the very interesting TenneT report provides useful observations and advice.

This report shows the need for an effective integrated European energy policy. Interconnections between countries are crucial here. The report also shows the need for good monitoring methodologies. For more information, we refer to the website of TenneT which also contains summaries in English:

If we reflect on the TenneT report, the study by the European Climate Foundation (ECF) from 2010, in which KEMA has been involved, comes to mind. We have already written about this in previous blogs, but we would like to make reference again to the Roadmap 2050 website; It is certainly worthwhile to read and reflect on the different studies, even though we are now 11 years later.

Potential of Green Hydrogen

Potential of Green Hydrogen

As can be viewed from previous blogs, we keep a close eye on the Hydrogen developments worldwide.

The International Renewable Energy Agency (IRENA) shows on their website an extremely useful overview of the possibilities and applications of Green Hydrogen. Furthermore it makes a good distinction between Fossil fuel based grey hydrogen, blue hydrogen, turquoise hydrogen and green hydrogen. Costs developments are elaborated and show the full potential in the areas of energy transition. For further detail, please click here ….

Notes:  the various types of Hydrogen are nicely shown by IRENA on their website:

  • Fossil fuel based grey hydrogen (source = methane of coal; process = steam methane reforming (SMR) or gasification).
  • Blue hydrogen (source = methane or coal; process = SMR or gasification with carbon capture).
  • Turquoise hydrogen (source = methane; process = pyrolysis).
  • Green hydrogen (source = renewable electricity (e.g. offshore wind energy and solar energy); process = electrolysis).
  • Majority of hydrogen produced today is grey hydrogen, but the potential for green hydrogen is huge.

We also refer to previous articles on our website:

The power of residential battery energy storage systems

The power of residential battery energy storage systems

The importance of applying significant focus on the actual implementation of energy storage as part of smart energy transition solutions.

A relevant quote from the report produced by SolarPower Europe ‘European Market Outlook For Residential Battery Storage 2020–2024’: “Last year, 745 MWh from 96,000 systems were installed, representing a 57% annual growth rate. The foundation for the European residential BESS sector was laid by a handful of countries, where a large residential solar market already, exists – namely Germany, Italy, UK, Austria, and Switzerland. These Top 5 markets absorbed over 90% of all BESS installations in 2019 and are also responsible for a similar level of the nearly 2 GWh of operating residential storage capacity in Europe so far.”. (Note: BESS stands for Battery Energy Storage Systems).

Please refer to the information accessible via the link by clicking here. The analyses and forecasts are a ‘must read’ for all working in the energy transition field.

The abovementioned report fully supports the developments and implementation success experienced elsewhere, by for example iwell; please refer to their website.

Another good example worth exploring, is the independent Dutch solar platform Zonatlas NL, freely accessible for individual households and individual business (e.g. SME). Zonatlas has for several regions in the Netherlands an on-line battery storage option available in case an individual household wants to make a connection with the energy generated by solar panels – please refer to the following website for more information:


The author of this blog as well as the Dutch companies EnShared and Zonatlas made a contribution to the Position paper ‘Virtual Energy Plants through Energy Commons’, which was recently issued by the independent foundation Future Energy Systems – please refer to: Energy storage prominently features in this Paper, as it is an essential component in creating virtual energy plants. And when, for example, sufficient storage capacity is connected to the micro-grid, self-balancing and the trading of stored electricity can also be exploited. These storage systems provide another important form of flexibility to the market and will gain greater public interest as the share of renewables increases.


IEA World Energy Outlook 2020 clearly states: “Solar becomes the new king of electricity…..”. This makes the role of storage more important for affordable and reliable energy systems in the near future.

For further information, please click here, but the following quotes from IEA’s WEO 2020 are worth mentioning here:

  • “Renewables grow rapidly in all our scenarios, with solar at the centre of this new constellation of electricity generation technologies. Supportive policies and maturing technologies are enabling very cheap access to capital in leading markets. With sharp cost reductions over the past decade, solar PV is consistently cheaper than new coal- or gas fired power plants in most countries, and solar projects now offer some of the lowest cost electricity ever seen.”.
  • “Storage plays an increasingly vital role in ensuring the flexible operation of power systems, with India becoming the largest market for utility-scale battery storage.”.


In the Netherlands many realise that the current and past tax and subsidy regime hasn’t really supported the large scale implementation of energy storage to date. Nevertheless, we observe good examples of implementation in for example apartment buildings where a smart battery system significantly lowers the peaks in the power supply resulting from the elevator usages.

It’ll be obvious that in the Netherlands we should focus more and more on the smart introduction of battery and energy storage systems.

We will continue to write about future developments.


Note (re.

A Virtual Energy Plant through an Energy Common is a network of local small- and medium scale power and heat generating units such as wind farms, solar parks, and Combined Heat and Power (CHP) units, as well as flexible energy consumers and storage systems. The interconnected units are dispatched through an automated central ‘control room’ of the Energy Common thereby remaining independent in their operation and ownership. The objective of a community based Virtual Power Plant is twofold. First, it needs to generate enough renewable energy for the local community. Secondly it should relieve the load on the electricity grid by smartly distributing the power generated by the individual units during periods of peak load. In case of a surplus, the combined power generation and power consumption of the networked units in the Virtual Energy Plant can be traded on the energy exchange.

Foundation Future Energy Systems

Foundation Future Energy Systems

The Foundation Future Energy Systems (hereinafter: FES) was established on August 14, 2020. FES aims to join forces within different sectors in the field of energy, area development and social innovation in order to contribute to a more inclusive, just and sustainable society. What motivates the foundation is collaboration and co-creation, learning from experiences, and allowing each other’s complementarity to work to the benefit of all. Decisiveness, with a strong support organisation. The core focus is supporting energy cooperatives and neighbourhoods and helping to set up energy commons. The aim of the Foundation is not to make a profit, and the ANBI status will be applied for. For more information, see:

The Energy Commons Institute (ECI) was established in October 2019. Due to advancing insights regarding the objectives and in view of the experiences of the past year, it was decided to rename the foundation and to discontinue the ECI foundation. This is in line with the ideas and activities of the social and sustainable innovations advocated by the initiators. This new foundation FES – like ECI – has an independent vision of technological developments that promote the energy transition. With today’s science and developments, a sharpened mission and new approach are in line with this. An example of the activities of the new foundation FES is the support of energy markets for the pooling of flexibility in which benefits flow back to households as much as possible. Another example is supporting the development of new technologies and software, based on Open Source principles, which are necessary to enable an affordable energy transition for households and companies. With this review, the new foundation fits in seamlessly with the recently presented vision of Europe: “Recovery and preparation for the next generation”;
