European & US Renewable Energy Targets | Renewable Energy World Magazine Article - 0 views

  • Latest data show, however, that in 2010, the indicative targets the member states set themselves for the electricity and transport sector were missed by most member states and the EU overall.
  • 'It is the fifth consecutive year that renewables have accounted for more than 40% of new electricity generating installations,' said Zervos.
  • By 2035, 80% of America's electricity will come from clean energy sources'.

Interview of Brad Edwards - Space Elevator Expert by Sander Olson - 0 views

  • Here is the Brad Edwards interview. Dr. Edwards received his PhD in physics in 1990, and worked at Los Alamos National Lab for 11 years. After leaving Los Alamos, Dr. Edwards has dedicated his career to researching and developing the space elevator concept. All of his research indicates that the space elevator concept is valid and feasible. He currently heads a company called Black Line Ascension, which is actively promoting the space elevator concept. He has published several books on the space elevator, including The Space Elevator: A Revolutionary Earth-to-Space Transport System, and Leaving the Planet by Space Elevator.

les panneaux solaire - Le 20 heures - Les journaux télévisés de France 2 - FO... - 0 views

  • Je ne sais pas si tu te rends compte mais un lingot permet de faire 4 panneaux solaires de 1m² qui produisent 4x130w et qui ont une durée de vie de 20ans. si tu n'utilises que les chutes de lingots, il faut 6 lingots pour faire 1 panneaux qui produira 130w avec une durée de vie de 20ans (pour faire un panneaux en poly silicium donc avec les chutes des lingots, il faut encore faire fondre les chutes 1400°C pendant quelques heures). Imagine maintenant l'énergie qu'il faut pour faire 4 panneaux solaire (9x24heures à 1200°C), l'énergie qu'il faut est beaucoup plus importante que ce que 4 panneaux de 130w pendant 20ans peuvent produire (et là je parle que de l'énergie). En gros un panneau solaire de 130w ne rembourse pas l'énergie qu'il a eu besoin pour être fabriqué  c'est bien le problème des média qui ne parlent que des bonnes choses de ces panneaux et qui arrive à faire croire à des personnes comme toi que c'est écologique.  
  • la plupart des panneaux solaires en silicium proviennent des déchets de l'industrie microélectronique
  • fabrique les panneaux solaires, les lampes à DEL, les processeurs,.... je vais parler du monde du silicium. La base de ces panneaux solaire est donc le cristal silicium pur, pour obtenir ce silicium on met du sable (SiO2) dans un creusé et on le fait fondre à 1400°C. Une fois le silicium  fondu et les molécules d'oxygène évacué, on plonge un germe de cristal de silicium dans le creusé que l'on tire tout doucement (1mm/15min) afin d'obtenir un cristal du silicium.   Il faut environs 24 heures pour obtenir un lingot de silicium et pendant ce temps le creusé doit resté à 1400°C. S’en suit une purification du lingot, on recuit le lingot 5 à 6 fois à 1000°C pendant à chaque fois 24 heures cela fait beaucoup beaucoup d'énergie et donc beaucoup beaucoup de CO2.   Une fois le lingot pur obtenu, il faut le découper et le polir (là on utilise beaucoup d'eau il ne faut pas que le silicium chauffe). S’en suit alors la réalisation du système, là il s’agit d'une répétition de dépôt de résine toxique, cuisson, attaque chimique (acide fluoridrique), dépôt chimique (silane SiH4 et Tétrafluorosilane SiF4 qui produit des gaz fluoré très toxique avec une duré de vie de 150ans) généralement l'opération est répété 40 fois environ. Après les systèmes obtenu il faut les découpés, mettre dans des boitiers,...  Bien sur, je ne parle pas du transport car la plupart des systèmes sont fabriqué en Asie, il y a aussi des à côté comme les salles blanches,.... les ordinateur qui tourne 24 heures sur 24 7jours /7.  Il faut 1 lingot pour fait 4 panneaux de 1 m²

  • produire 1m² de panneaux solaire engendre plus de CO2 que se qu’il permet d’évité de rejeter et donc il n’a pas d’intérêt dans la lute contre le changement climatique. Par contre c’est une bonne alternative pour la fin du pétrole (si on n’a pas peur de la pollution)
  • la fabrication d'un panneau produit plus de CO2 que se qu'il évite de rejeter le temps de sa durée de vie
  •  
    in fr ... but perhaps you know that photovoltaïc panels are polluting massively .. just to build them !!! and have not enough power to reimburse their fabrication back !!! and if there is no more oil to build them .. what's up ?

ECREEE Validation Workshop on Renewable Energy and Energy Efficiency Policies and Scena... - 1 views

  • The Commission of the Economic Community of West African States (ECOWAS) works towards a voluntary commitment to the Sustainable Energy For All Initiative of the UN Secretary General presented at the Rio+20. In a regional workshop, held from 25 to 27 June 2012 in Dakar, Senegal, the Directors of the ECOWAS Ministries of Energy agreed on the main targets and pillars of a regional renewable energy and energy efficiency policy of ECOWAS. The policies aim at the following objectives: Around 30% of the electricity consumption in the ECOWAS region will be saved through demand and supply side efficiency improvements by 2030. The share of renewable energy (incl. large hydro) of the total installed electric generation capacity of ECOWAS will increase to 35% in 2020 and 48% to 2030. The share of new renewable energy such as wind, solar, small scale hydro and bioelectricity (excl. large hydro) will increase to around 10% in 2020 and 19% in 2030. These targets translate to an additional 2.425 MW renewable electricity capacity by 2020 and 7.606 MW by 2030. To provide universal access to energy services it is envisaged that around 75% of the rural population will be served through grid extension and around 25% by renewable energy powered by mini-grids and stand-alone systems in 2030. By 2020 the whole ECOWAS population will have access to improved cooking facilities either through improved stoves or fuel switching to other modern forms of energy such as LPG. The share of ethanol/biodiesel in transport fuels will increase to 5% in 2020 and 10% in 2030. By 2030 around 50% of all health centers, 25% of all hotels and agro-food industries with hot water requirements will be equipped with solar thermal systems.

Travel Green: Bicycling in the City : Sustainablog - 0 views

  • For years, I was a public transit aficionado, constantly trumpeting the benefits of buses. I have to admit, though, that it didn’t take me long to swear off buses (and their rising costs to ride) forever, in favor of a totally free bicycle that could spirit me off to anywhere–back alleys and unique routes included.

Battery technology charges ahead - McKinsey Quarterly - Energy, Resources, Materials - ... - 0 views

  • Most experts agree that prices for energy storage will fall in coming years, but disagree over how far and how quickly. This is an important debate because a significant drop in battery prices could have wide-ranging effects across industries and society itself. In particular, cheaper batteries could enable the broader adoption of electrified vehicles, potentially disrupting the transportation, power, and petroleum sectors.

France and Spain seek compromise on power grid linkage | EU - European Information on E... - 0 views

  • Financing and planning concerns also plague the project, with the level of state subsidies to the two main contracting firms - RTE (Réseau de transport électricité) and REE (Red Electrica de Espana) - still to be determined, and with questions remaining about the exact location of the future power cables.
  • Concerns include the potentially destructive impact of constructing electricity infrastructure in local communities and sensitive environments, and local civic organisations have mounted highly organised campaigns to contest the project, arguing that they have been given insufficient justification for the construction of the necessary power lines.

Motor Authority » Honda investigating 'Rankine Cycle' to power hybrids - 0 views

  • Conventional internal combustion engines waste a lot of energy in creating heat, but by applying a ‘Rankine cycle,’ a process where hot exhaust gases are used to heat up a water reservoir and create steam to spin a turbine, electricity can be generated. This electricity can then be used to charge up an array of batteries and help power a hybrid-electric powertrain.
