Trees versus humans
Once upon a time, we crawled out of the sea. Crawled around on land for a while, but there was nothing to do there, so we migrated back to the sea. Millions of years later we went back to look… Continue Reading

From EROI to EROLI: energy return on Land investment ? 2/2
In the agricultural project that I described in my previous contribution [1], which was initially about the EROI, the energy return on energy investment, I subsequently calculated the effects back to land’input’. But then the thought soon arised: would is… Continue Reading
EROI and land use of potato crop – a pilot 1/2
In a recent project , ‘Verrijkende Landbouw’ ( Enriching Agriculture) [1], I was able to refine the theory and methodology of MAXergy, using Embodied Land as an indicator [2], thanks to a practical pilot. As follows. Agriculture needs to change.… Continue Reading
Carbon storage in wood-timber 1/2
Storage (binding) of CO2 in wood/timber is a hot issue at the moment*. But how should that be calculated really? Before I go into more detail, a few preliminary remarks: (the part on ‘calculating’ has been later added, and ‘CO2’… Continue Reading
DELY : Disabled Earth Life Years
We can develop beautiful so-called scientific methods to calculate all the effects of our impact, but in the end only two data are relevant: energy and material use, and the rest is derived from that: all emissions, to air or… Continue Reading
Energy poverty ? No, energy luxuriance
I recently was triggered a few times by the term: ‘Energy Poverty’ in all kinds of reports and tweets [1-4] . Usually referred to as having little access to oil, gas and coal, in what is then called the poorer… Continue Reading
Land, between heaven and earth
It is intriguing how the world fundamentally works, with its cycles, driven mainly by solar energy. Which can be traced back mainly to the yields of land, as I found out earlier. [1,2] (Land that has virtually disappeared from economic… Continue Reading
land (-potential) as the new money standard
Someone suggested recently to think about a new money standard. Well, thats a challenge, so I did. Since money is a virtual unit of trade, not based on any actual value. Not anymore, at least, since we left the barter… Continue Reading
Biomass (-growth) is our reference : Back to the forests
By now its obvious: the way we are currently dealing with climate, environment, raw materials, food, biodiversity, will not help us prevent disasters. But what then? The struggle and discussion on solutions is in full swing currently. Just look at… Continue Reading
biomass for energy? (not) again… 2/2
Biobased resourcing is hot. Which is understandable, of course, they grow by themselves, (its solar energy), they capture CO2, require little energy to process, and know multiple uses. You can built with then, heat, or create high-value resources, like in… Continue Reading
