PiM Mini Model on Associated Costs by Kai Neumann

Step 1 Level Resource 1 Resource A Target Finished (Step 2) Finished (Step 1) Overall Costs Total Costs Step 3 Value of Target Step 2
This mini model shows one of two ways to calculate costs within PROCESS-iMODELER models. Costs can be either as shown here the directly associated costs or like shown in another model the costs of the availability of the resources. For the associated costs you simply connect the process factors to a normal factor and use the costs() function times the process. The costs() value of each process step is the sum of the costs (a parameter of the resource- and level-resource factors) that are connected with t...

Are investments into green energy macroeconomically costs? by Kai Neumann

Jobs Economy Almost free wind, solar and water power Spending power elsewhere Others continue to use fossil energy Economy elsewhere Jobs elsewhere Investments into green energy Cost of energy elsewhere Continued use of fossile energy Costs of energy Spending Power
This qualitative model and its description in the presenter shows an interconnected view of the advantages and disadvanteges of today's investments into green energy.

Tesla's Powerwalls seen in context by Kai Neumann

investments into clean energy photovoltaics and/or wind power good feeling of 100 percent independence cool gadget to be proud of cool things to buy less purchase power Powerwall, solution to store energy being part of the smart grid cleaner environment, future for our children our happiness economies of scale more people share new values
Just a small qualitative model for a discussion on linkedin on the economics of Tesla's Powerwalls. Here is the original article the discussion is based on: http://www.forbes.com/sites/christopherhelman/2015/05/01/why-teslas-powerwall-is-just-another-toy-fo...

The rise of resistance against climate policies by Kai Neumann

protection of environment need to change State of environment right memes resignation, no self-efficacy small steps, role models opposition media lobbyists wrong memes resistance to politics obvious need to protect the future
Whether it is Germany's "Heizungsgesetz" or the European Union's "Renaturation Law" there is a certain pattern how resistance evolves. Recently I was on workation sailing the Baltic Sea observing lots of signs of movements against the implementation of protected natural habitats in the Baltic Sea. The fishing 'industry', the tourism, and the water sports enthusiasts all seem united in their protest against the protection of the Baltic Sea. Fact is, that the Baltic Sea is in an extremely poor condition ca...

Charitable things could be financed Others could get a higher income The person helped to make a much higher profit Others also get high income High Income of a Person
A tiny qualitative model that asks how it is possible that many managers earn that much money and even get big exit packages even if they were not successful.  Note there is no balancing feedback loop but a number of reinforcing feedback loops. Not also that everybody with an income above average that rejects to earn less is part of the development.

Preiselastizität by Franc Grimm

Marktpreis Neu Preisveränderung Impuls Preisveränderung in % Berechnung Marktpreis Marktpreis Veränderung Marktpreis alt Differenz Angebot Nachfrage Nachfrage Neu Nachfrage Änderung Angebot Nachfrage Änderung in % Preiselastizität
Die Preiselastizität ist ein Maß dafür, welche relative Änderung sich bei der Angebots- bzw. Nachfragemenge ergibt, wenn eine relative Preisänderung eintritt. Je höher die Preiselastizität ist, desto stärker reagiert die Menge (hier Nachfrage) auf den geänderten Preis. Dieses Modell demonstriert die grundsätzlichen Mechanismen anhand eines Mini-Beispiels. Eine besondere Form der Preiselastizität ist die Kreuzpreiselastizität, bei der dargestellt wird, wie sich die Preisänderung eines Gutes auf die Mengen...

Sinnhaftigkeit von Energiestandards in Gebäuden by Kai Neumann

Steigender CO2 Preis Wohlfahrt Energiefußabdruck erneuerbare Energien Bedarf Ausbau erneuerbarer Energien Energieverbrauch Anteil erneuerbarer Energien Treibhausgase Kosten Aufwand Dämmung u. Technische Gebäude Anlagen Energiefußabdruck Dämmung etc. Recycling EE Wertschöpfung im Inland
Ausgangsthese: Wir verwenden heute nicht-erneuerbare Energien zur Herstellung von Dämm-Materialien, die sich erst über Jahrzehnte auszahlen sollen, wenn wir unlängst erneuerbare Energien haben. Frage also, ob wir nicht lieber weniger dämmen und dann eben den Energiebedarf mit erneuerbaren Energien decken oder ob der Mehrbedarf an nicht-erneuerbaren Energien heute gerechtfertigt ist, da der Mehrbedarf an erneuerbaren Energien in der Zukunft auch zu bewerten ist. Zu bewerten in mehrerlei Hinsicht:  kann de...
