Wind energy potential of Germany - Limits and consequences of large-scale wind energy use
Axel Kleidon
The transition of our energy system to renewable energies is necessary in order not to heat up the climate any further and to achieve climate neutrality. The use of wind energy pla…
Estimating the technical wind energy potential of Kansas that incorporates the atmospheric response for policy applications
Jonathan Minz, Axel Kleidon, Nsilulu T. Mbungu +1
Energy scenarios and transition pathways need estimates of technical wind energy potentials. However, the standard policy-side approach uses observed wind speeds, thereby neglectin…
How to sustain the terrestrial biosphere in the Anthropocene? A thermodynamic Earth system perspective
Axel Kleidon
Many aspects of anthropogenic global change, such as land cover change, biodiversity loss and the intensification of agricultural production, threaten the natural biosphere. These…
Triggering A Climate Change Dominated "Anthropocene": Is It Common Among Exocivilizations?
Ethan Savitch, Adam Frank, Jonathan Carroll-Nellenback +3
We seek to model the coupled evolution of a planet and a civilization through the era when energy harvesting by the civilization drives the planet into new and adverse climate stat…
Physical limits of wind energy within the atmosphere and its use as renewable energy: From the theoretical basis to practical implications
Axel Kleidon
How much wind energy does the atmosphere generate, and how much of it can at best be used as renewable energy? This review aims to give first-order estimates and sensitivities to a…
Empowering the Earth system by technology: Using thermodynamics of the Earth system to illustrate a possible sustainable future of the planet
Axel Kleidon
With the use of the appropriate technology, such as photovoltaics and seawater desalination, humans have the ability to sustainably increase their production of food and energy whi…
Understanding the Earth as a whole system: From the Gaia Hypothesis to Thermodynamic Optimality and Human Societies
Axel Kleidon
The notion that the whole is more than the sum of its parts has a long tradition in science. This, of course, also applies to the Earth system. With its myriad of processes, spanni…
What limits photosynthesis? Identifying the thermodynamic constraints of the biosphere within the Earth system
Axel Kleidon
Photosynthesis converts sunlight into the chemical free energy that feeds the Earth's biosphere, yet at levels much lower than what thermodynamics would allow for. I propose here t…
Earth as a Hybrid Planet - The Anthropocene in an Evolutionary Astrobiological Context
Adam Frank, Axel Kleidon, Marina Alberti
We develop a classification scheme for the evolutionary state of planets based on the non-equilibrium thermodynamics of their coupled systems, including the presence of a biosphere…
Geographic variation of surface energy partitioning in the climatic mean predicted from the maximum power limit
Chirag Dhara, Maik Renner, Axel Kleidon
Convective and radiative cooling are the two principle mechanisms by which the Earth's surface transfers heat into the atmosphere and that shape surface temperature. However, this…
How does the earth system generate and maintain thermodynamic disequilibrium and what does it imply for the future of the planet?
Axel Kleidon
The chemical composition of the earths atmosphere far from equilibrium is unique in the solar system and has been attributed to the presence of widespread life. Here I show that th…
Thermodynamics of chemical free energy generation in off-axis hydrothermal vent systems and its consequences for compartmentalization and the emergence of life
E. Simoncini, A. Kleidon, E. Gallori +1
In this paper we demonstrate how chemical free energy can be produced by a geological process. We provide a thermodynamic framework in which to assess how life emerged at the off-a…
