Geothermal heatingGeothermal heating is the direct use of geothermal energy for some heating applications. Humans have taken advantage of geothermal heat this way since the Paleolithic era. Approximately seventy countries made direct use of a total of 270 PJ of geothermal heating in 2004. As of 2007, 28 GW of geothermal heating capacity is installed around the world, satisfying 0.07% of global primary energy consumption. Thermal efficiency is high since no energy conversion is needed, but capacity factors tend to be low (around 20%) since the heat is mostly needed in the winter.
Paradigmethumb|250px|Universum, C. Flammarion, gravure sur bois, Paris 1888. Un paradigme est — en épistémologie et dans les sciences humaines et sociales – une représentation du monde, une manière de voir les choses, un modèle cohérent du monde qui repose sur un fondement défini (matrice disciplinaire, modèle théorique, courant de pensée). . Le sens français désigne un exemple linguistique. Les paradigmes sont, selon le philosophe des sciences Thomas Samuel Kuhn des .
Regenerative designRegenerative design is an approach to designing systems or solutions that aims to work with or mimic natural ecosystem processes for returning energy from less usable to more usable forms. Regenerative design uses whole systems thinking to create resilient and equitable systems that integrate the needs of society with the integrity of nature. Regenerative design is an active topic of discussion in engineering, landscape design, food systems, and community development.
