Preventive War

The term “Preventive War” is staging a revival in international politics. The recall of the famous quote “war is the continuation of politics with other means” from Clausewitz encompasses the idea of a pre-emptive strike and entering into war to avoid an enemy to grow too powerful at a later stage. In the age of weapons of mass destruction and the non-proliferation of nuclear weapons, an intervention to limit the spread of nuclear weapons has taken the form of a preventive war. The international community has been quite unsuccessful to limit the spread of nuclear weapons so far. Research shows that democracies are less likely to go to war than authoritarian regimes and dictatorships.
The preventive war strategy (Levy, 2008), however, is a means for democracies to defend their survival against the spreading and warmongering of authoritarian regimes. However, preventive war, by definition, is a war. The preventive aspects derives from the logic to avoid a much more devastating later war. There is a longitudinal assessment at the base of the calculation to enter now into a preventive war, rather than later into a more difficult defence. In anticipation of the defense, a pre-emptive strike is undertaken. In international politics the lack of a “policing of treaties and international agreements” has initiated the return of the neoclassical concept of national interest as a guiding principle for nation states. A continued threat to the survival of a state, Israel as an example, by the Iranian dictatorship makes the application of a preventive war strategy more likely.
Historically, democracies have applied such military strategies as a continuation of politics and diplomacy with other means. In this sense the 21st century is apparently no different from previous centuries. The revival of “Realpolitik” has been spurred by Putin and his war on Ukraine territory since 2014. How and when to return to the negotiation table is the litmus test of the preventive war strategy.

Home Cloud

Our homes have entered the process of virtualization. Not only our collections of photographs, videos of and from family and friends have been stored on cloud servers and services for some time. Homework and school materials are distributed from clouds and the size of such collections quickly reach levels beyond any hand held devices. Hence, the home cloud or your private cloud will be the next option to think about. The safe storage of information, which is intended to be shared amongst many persons, or just private backup solutions find their home on your private cloud. The technology is available at moderate costs, but allows additional safety and flexibility. Your digital home is available wherever you are. No need to carry around with you physical backup devices. Just like for keys, you have to manage access rights to the data and take care of basic security features. It is a bit like running a small enterprise. You have to make sure that users of your home cloud apply basic internet security standards like safe passwords, for example. Similar to the storage in a basement from time to time clearing out duplicates or forgotten items may help to preserve sufficient transparency of what is stored. However, digital tools may help with that task as well. We may enjoy a stroll outside and watch the clouds pass by knowing that our data are fairly safe in their very own home cloud.

Home cooling 2

As a consequence of global warming architecture has to cater for the cooling of our homes as well. The 1st option is to keep the heat outside. Isolation is key in this respect as well. Colors outside have a long tradition in protecting against heating up due to abundant sunshine. Doors and windows ask for additional protection as well. Historically, trees have been instrumental in providing shade for homes. Greening of facades is another natural option. For a long time homeshomes have been built above an underground floor or a cellar. Originally these naturally cool rooms served as storage rooms for food and drinks. Nowadays, such basements offer additional cool space during (exceptionally) hot summer days. The distribution of cool air from basements to upper floors is an alternative way of cooling, which uses little energy. For newly built homes this is another reason to drill builders drill. Even office space has been built in this way, much appreciated during the warm seasons. (Image: Paris UNESCO headquarters office space).

Home Energy

Energy production and consumption in a home are determined by many factors. The number of persons in a household has, of course, a considerable impact on consumption patterns. The investment in home energy production can cover the basics, but is less likely to cover peaks of consumption like friends on a visit wanting to charge their electric vehicle.
In a test with a simple small scale solar panel (fixed on a balcony for example with 860W peak) it was possible to produce a full days consumption on a sunny summer day for a 1-2 person household without use of electricity for personal mobility, but hot water through heat pump provision. The potential for an own production of electricity during summer months is within reach without major behavioral changes.
Okay, digital steering of energy consumption for hot water during hours of bright sunshine and washing machine around high noon are not for everybody to program or carry through.
Digital tools complement the energy consumption at the right time. There is a lot of power in sunshine. The usual caveats of bad weather and winter months change the calculations. The return on investment or break even point needs 300 days of about 2 kWh to recover the 500€ initial costs of the solar panels. After about 3 years the initial costs are recovered and savings begin to accrue. The bridge between energy theory and practical applications is to be found in experimental setups and tests of different scenarios for the modern “prosumer” of the 21st century.

Energetic Architecture

The link between energy and architecture is all to obvious. For at least a century we believed that energy had to serve architecture and could be relegated to second place. With global warming the overriding importance sits with energy concerns for some years to come. We spend billions to repair the bad architectural and fast growth architecture of the post 2WW era of architecture, especially the construction boom of the 60s and 70s. The driver of change in architecture has moved from the period of social architecture (60s, 70s) to energetic architecture. Energy in architecture has multiple dimensions. Whereas a century ago the shift consisted in the installation of central heating systems in the northern hemisphere of the globe at scale, in the 21st century the concern there shifts to isolation from heat (and cold) to more efficient, less polluting energy provision. Cooling houses and office spaces during extended periods and higher peeks of heat, ask for substantial revisions of existent architecture and the next generation of energetic architecture. Before long, we shall also think more seriously about the handling of water in architecture, a topic which is closely linked to energy consumption and design.
From a sociological point of view we are used to ask questions of social inequality related to this issue as well. We are on the way to move into a society of energy-rich versus energy poor households and enterprises. Financing of adaptations of housing and offices to the energetic challenges is likely to create severe additional inequalities, which exacerbate the already existing ones. If you have no money to spare, you will be unable to invest into energy savings with more distant returns on investment (ROI). At older age you are less resistant to heat waves and causes health disadvantages. If previous investments were impossible or the urgency for energetic architecture was neglected for too long, additional health inequalities shall arise.
The “Deutsches Architekturmuseum” has built an exhibition around this theme, which widens the perspective of architecture and energy. This highlights the additional concern for energetic architecture and people living or working in (modern) architecture.

Global warming

The annual update of the global warming indicators (source: Earth system science data 2025-6) gives more reasons to worry about the future of our climate. The objective to limit global warming to +1.5°C, established at the Paris climate agreement in 2015, is no longer achievable. This is the hard evidence based on the global network of scientific data collections and their projections. Fossil fuels are a major cause, deforestation and greenhouse gas emissions as well (Forster et al. 2025). As a consequence, human-induced warming of average surface temperatures and flows of heat into oceans continue. The first consequences, we witness in many parts of the world already. France is particularly affected (Le Monde 2025-6-20, p.7). What used to be called “natural disasters” is better described as long-term consequences of human-induced global changes like global warming. About time to take our CO2 footprint even more seriously. The “All electric society” can reduce reliance on fossil fuels considerably, as of now.

Fertility Fecundity

The scientific debate around changes in fertility has focused on social, economic and cultural factors to explain the drop in total fertility rates in OECD countries. The baby boom years of the 1950s and early 1960s had come to an end following the spread of new forms of birth control like contraception from the late 1960s onwards. The trend is very obvious and yet, the explanations of the trend might lack a more profound analysis of fecundity in addition to the socio-economic explanations. Shakkebaek et al. (2025) point for example to the little known effects of environmental (pollution) factors on the biological reproduction capability of humans (men and women).
Additionally, psycho-social factors like “the German Angst” fear about future developments in many social and economic fields might have direct effects, but also indirect effects on human biology. We know still very little about such feedback loops or feedback effects. We are more convinced, than we actually have hard evidence, that the BSP, SPB or PSB (B=Bio, S=Social, P=Psycho) spheres are interwoven, but an ambitious research agenda is called for to enlighten the issue. The big invisible elephant in the room might be environmental issues that enter into the fertility equations more than we have expected for many years. A nice working hypothesis for an ambitious and overdue research agenda.

Real dad-ication

The last few years there has been a stronger recognition of the need to get fathers more involved in caring for children. In the USA the #dadication became a symbol and an annual campaign to raise awareness to the importance of fathers to get involved in addition to mothers. The combination of fatherhood and dedication was shortened into “dadication” to reflect the combination of both elements that we not always considered to a natural part of fatherhood. It is a win-win-win situation as fathers gain emotional strength, children learn about parental styles and mothers get some relief from at times overwhelming family care.
In literature we have some great examples of caring or neglecting fathers. Famous are the letters to his father by Franz Kafka. Historically, fathers have often thought their role solely as ensuring a social status for their children, but nowadays the role patterns is much broader and much more emotional or psychological as well. As there are more “dadication” role models around, the song “Papa où te” (Dad, where are you?) will still be popular, but with more reassurance that children or adolescents have vivid memories of time spent together.

Ohm … Ohm

In the 21st century most people will interpret “Ohm … Ohm” as the exhalation in yoga  (Hatha yoga). Therefore, take a deep breath, hold it for a while (twice as long) and then exhale (thrice as long), for example. Now you are perfectly set up to read about Georg Simon Ohm (1789 – 1854), the physicist after whom Ohm’s law was named. In the “All electric society” Ohm’s law still plays a fundamental role for all households. The understanding of electric circuits is quite easy, just apply the basic relationship of Ohm’s law. In a resistor the current and voltage are proportional. The sign (SI) for resistance (R in physics) of a conductor is the Greek letter Ω. The proportionality is expressed as R = V/I where V is the Voltage and I the current through the conductor. The units are Ω, Volt V, Ampere A. All you need to know additionally is the calculation of the power P in Watt W where P = V x I for example. If you want or need to dig deeper into your home electricity just study a bit of electrical technology on the basics.
In our homes, apartments or offices we can apply this 200 years old knowledge to guide the safety and energy consumption of our electric installations. Maybe with the help of a spreadsheet programme like excel etc.

Home cooling

In the summer months, in Europe, the concern shifts from heating your home to cooling your home. For generations this has been possible without use of air conditioning. A natural way of cooling has been for centuries to dig into earth to take advantage of the rather stable and cool temperatures underground. In home building this has also been a tradition for centuries to build cellars underneath a home.
Wine growing regions have used the cellar as a natural cooling facility for long and short term storage of wine. Digging into a mountain of a valley offered a natural cool storage solution for years without additional energy consumption. Modern buildings should return to this practice and gain cold from below the surface to cool buildings in the warm or hot seasons. Good isolation combined with the cool temperatures from below the surface in summer months will substantially save energy and thereby CO2 emissions. Circulation of the cool air from below to the upper floors is the issue as well as dealing with differential humidity levels. The wisdom of previous generations in home building with no access to air conditioning (avoiding the air conditioning paradox) is likely to experience a revival in the coming years.
Coolness is the new and old wisdom.
