Agen. Une villa «passive» au concept révolutionnaire | Sustain Our Earth | Scoop.it

Une villa d'architecte à énergie passive a été construite par un collectif de professionnels «EQUIP'17» à Estillac. Une maison cubique, d'exception pour ses atouts.

 

Le concept est révolutionnaire. La première villa témoin dite «passive» vient d'être inaugurée à Estillac, au lieu-dit «Bordeneuve». Inspirée des villas cubiques de Palm Springs en Californie, cette maison d'architecte offre de sérieux atouts. Créée par le collectif d'industriels et d'entreprises du bâtiment «ÉQUIP'17», cette villa se veut pilote en France. Façades en béton et menuiseries en aluminium respirant et triple vitrage signées Garrigues, sont conçues à l'usine La CIR de Tonneins spécialisée dans le béton.

Human domination of the biosphere: Rapid discharge of the earth-space battery foretells the future of humankind

Human domination of the biosphere: Rapid discharge of the earth-space battery foretells the future of humankind | Sustain Our Earth | Scoop.it

Earth is a chemical battery where, over evolutionary time with a trickle-charge of photosynthesis using solar energy, billions of tons of living biomass were stored in forests and other ecosystems and in vast reserves of fossil fuels. In just the last few hundred years, humans extracted exploitable energy from these living and fossilized biomass fuels to build the modern industrial-technological-informational economy, to grow our population to more than 7 billion, and to transform the biogeochemical cycles and biodiversity of the earth. This rapid discharge of the earth’s store of organic energy fuels the human domination of the biosphere, including conversion of natural habitats to agricultural fields and the resulting loss of native species, emission of carbon dioxide and the resulting climate and sea level change, and use of supplemental nuclear, hydro, wind, and solar energy sources. The laws of thermodynamics governing the trickle-charge and rapid discharge of the earth’s battery are universal and absolute; the earth is only temporarily poised a quantifiable distance from the thermodynamic equilibrium of outer space. Although this distance from equilibrium is comprised of all energy types, most critical for humans is the store of living biomass. With the rapid depletion of this chemical energy, the earth is shifting back toward the inhospitable equilibrium of outer space with fundamental ramifications for the biosphere and humanity. Because there is no substitute or replacement energy for living biomass, the remaining distance from equilibrium that will be required to support human life is unknown.

North Korea to fight food insecurity and natural disaster with trees | Sustain Our Earth | Scoop.it
Experts in DPR Korea intend to restore the quality of forest lands, alleviate wide-spread food insecurity and reduce the frequency of natural disasters in the country through an ambitious programme of agroforestry "the use of trees on farms and in the landscape". The DPR Korea is only the second country in Asia to launch such an initiative.

Computer simulation shows climate mitigation schemes could result in increased water stress

Computer simulation shows climate mitigation schemes could result in increased water stress | Sustain Our Earth | Scoop.it
(Phys.org)—A combined team of researchers from Pacific Northwest National Laboratory and the University of Maryland has created a computer simulation meant to show the degree of water stress in the U.S. going forward into the future—it shows that under some conditions, water stress may actually increase due to mitigation efforts designed to slow global warming. In their paper published in Proceedings of the National Academy of Sciences, the team describes their simulation and why they believe it shows the dangers of not clearly thinking through strategies meant to help reduce greenhouse gas emissions.

End-of-century Manhattan climate index to resemble Oklahoma City today | Sustain Our Earth | Scoop.it
Climate change caused by greenhouse gas emissions will alter the way that Americans heat and cool their homes. By the end of this century, the number of days each year that heating and air conditioning are used will decrease in the Northern states, as winters get warmer, and increase in Southern states, as summers get hotter, according to a new study from a high school student, Yana Petri, working with Carnegie's Ken Caldeira. It is published by Scientific Reports.

Rethinking Algae Biomass Production | Sustain Our Earth | Scoop.it
Algae is a wonder of the natural world. It’s a highly adaptable organism, one that grows in both fresh and saltwater and can thrive in some of the harshest conditions. For that reason, hundreds of strains of algae exist across the globe. If you find a place with water, sunlight and the right mix of nutrients, it’s very likely you’ll also find algae.

We know from studies on jet lag and night shifts that metabolism is linked to the body’s circadian rhythms. These rhythms, regular daily fluctuations in mental and bodily functions, are communicated and carried out via signals sent from the brain and liver.

Model shows how surge in wealth inequality may be reversed

Model shows how surge in wealth inequality may be reversed | Sustain Our Earth | Scoop.it
(Phys.org)—For many Americans, the single biggest problem facing the country is the growing wealth inequality. Based on income tax data, wealth inequality in the US has steadily increased since the mid-1980s, with the top 10% of the population currently owning about 73% of the country's wealth. In a new paper published in PLOS ONE, researchers have quantitatively analyzed several of the major factors that affect wealth inequality dynamics, and found that the most crucial factor associated with the recent surge in wealth inequality since the '80s has been the dramatic decrease in personal savings, followed closely by a large increase in the dominance of capital income over labor income.

The Future of Renewable Power in Mexico

The Future of Renewable Power in Mexico | Sustain Our Earth | Scoop.it
The abundance of diverse renewable energy resources, growing demand for power, macroeconomic stability, and historically high electricity prices continue to position Mexico as one of the most attractive destinations for investments in renewable power generation.  Despite enjoying some of the highest wind and insolation levels in the world, Mexico has yet to develop most of the potential of its renewable energy sources.  As of 2013, thermal sources represented 75 percent of Mexico’s installed capacity, followed by hydropower generation, which accounted for 19 percent of total capacity, while other renewable sources, such as wind, solar and geothermal energy represented less than 6 percent of electricity generation in Mexico.

World’s First Integrated Geothermal and Biomass Plant Goes Online

World’s First Integrated Geothermal and Biomass Plant Goes Online | Sustain Our Earth | Scoop.it

Enel Green Power has announced the completion of a 5 megawatt (MW) biomass power plant in Italy’s Tuscany region that integrates biomass with geothermal steam generation. A first of its kind, the newly constructed biomass plant will use locally sourced virgin forest organic matter and a “super-heater” boiler to increase steam temperatures at the nearby 13-MW Cornia 2 geothermal plant. Geothermal steam temperatures entering the Cornia 2 plant will be raised from 300 degrees to over 700 degrees (Fahrenheit). The result, according to Enel Green Power, will be an increase in the geothermal plant’s net electricity generation capacity.
