L'humanité a épuisé son crédit annuel de ressources naturelles renouvelables

L'humanité a épuisé son crédit annuel de ressources naturelles renouvelables | Solar Energy projects & Energy Efficiency | Scoop.it

Nous sommes « dans le rouge » et nous entrons en situation de déficit écologique, selon les données recensées par le Global Footprint Network, une organisation internationale de recherche environnementale a signalé le WWF.

Ainsi, le 19 août dernier, l'humanité a dépassé son quota en ressources naturelles pour l'année, soit un jour plus tôt qu'en 2013. 
Tous les ans, l'ONG Global Footprint Network calcule « le jour du dépassement » : la date à laquelle l'empreinte écologique de l'humanité dépasse la biocapacité de la planète à savoir sa capacité à reconstituer les ressources de la planète et à absorber les déchets, y compris le CO2. Cette date symbolise un budget disponible épuisé pour l'année.

Researchers Develop Transparent Solar Concentrator That Could Cover Windows, Electronics

Researchers Develop Transparent Solar Concentrator That Could Cover Windows, Electronics | Solar Energy projects & Energy Efficiency | Scoop.it

Scientists at Michigan State University announced this week the creation of a “transparent luminescent solar concentrator” that could turn windows and even cellphone screens into solar-power generators.

This technology could mean that one day entire skyscrapers might be able to generate solar power without blocking out light or ruining tenants' views.

The material works by absorbing light in the invisible spectrum (ultraviolet and near infrared) and then re-emitting it in the infrared. The infrared light is then channeled to the edge of the clear surface, where thin strips of photovoltaic cells generate the power.

Waste Electrical and Electronic Equipment Directive comes into force for PV modules in France

Waste Electrical and Electronic Equipment Directive comes into force for PV modules in France | Solar Energy projects & Energy Efficiency | Scoop.it

With effect August 23rd 2014, PV companies established in France must finance and ensure the waste treatment of the PV modules they sell and import.

Extending WEEE (Waste Electrical and Electronic Equipment Directive) to photovoltaic (PV) modules results in a legal obligation for France-based companies to organize the take-back and recycling of their discarded products returned to them by consumers and professionals.

“As far as the major PV module manufacturers are concerned, they anticipated the regulatory changes betimes, already integrating WEEE-compliance in their processes,” said Jan Clyncke, President at PV CYCLE France and head of Europe’s first PV-focused take-back and recycling scheme.

The Next Big Challenge for Energy Storage

The Next Big Challenge for Energy Storage | Solar Energy projects & Energy Efficiency | Scoop.it

The energy storage era is upon us. States like California and New York have adapted energy policies that will make it possible to economically deploy storage systems, while technology advancements have boosted performance and trimmed costs. For the first time in history it will become feasible to store electric energy.

These breakthroughs in turn will change the underlying infrastructure of our whole industry. Utilities in most jurisdictions are legal monopolies because it was the only way to economically and technically bring electricity to a society. Forcing companies to build competing grid networks and power plants would have led to bankruptcies, chaos and terrible service.

Recycling old car batteries into solar cells: Environmental twofer could recycle lead batteries to make solar cells

Recycling old car batteries into solar cells: Environmental twofer could recycle lead batteries to make solar cells | Solar Energy projects & Energy Efficiency | Scoop.it
This could be a classic win-win solution: A system proposed by researchers recycles materials from discarded car batteries -- a potential source of lead pollution -- into new, long-lasting solar panels that provide emissions-free power.

The system is described in a paper in the journalEnergy and Environmental Science, co-authored by professors Angela M. Belcher and Paula T. Hammond, graduate student Po-Yen Chen, and three others. It is based on a recent development in solar cells that makes use of a compound called perovskite -- specifically, organolead halide perovskite -- a technology that has rapidly progressed from initial experiments to a point where its efficiency is nearly competitive with that of other types of solar cells.

The Power of Collective Energy Purchasing

The Power of Collective Energy Purchasing | Solar Energy projects & Energy Efficiency | Scoop.it

"We can't do it as an individual, but four hundred communities aggregating and asking for local wind power and solar power — that's really powerful."

Oak Park, IL, is one of hundreds of Illinois towns using their authority to buy electricity in bulk on behalf of its residential and small business customers. So far, most communities have used the policy — known as community choice aggregation — to negotiate for less expensive electricity compared to the default electric utility, Commonwealth Edison. Many have also purchased renewable energy credits with their power, but it's not clear if the practice is greening or green-washing the power supply.

Long-Lasting Solid-State Batteries Are Nearing Production | MIT Technology Review | Solar Energy projects & Energy Efficiency | Scoop.it
Applied Materials has started shipping equipment that could help double the energy storage of batteries.

A type of battery that could eventually store twice as much energy as a conventional one could be about to move beyond niche applications to wearable devices, phones, and even electric cars.

Solid-state batteries, as they’re called, have been available for a while and are used in some wireless sensors, but they have been too expensive to use elsewhere.

This could clear the way for slimmer, longer-lasting smart watches as well as electric cars with a range similar to gas-powered ones.
