Electric Bus Picks up Passengers ... and Energy


"Tom Lombardo posted on March 18, 2013

Many years ago I bought a rechargeable battery-operated toothbrush with its own charging cradle. I noticed that there were no electrodes on the toothbrush or the cradle, and for a moment I wondered how it charged through the plastic. In a flash of inductive reasoning (sorry - I couldn't resist) I realized that the charging cradle and the toothbrush must be magnetically coupled. (This was long before iPhone charging pads.)

Increasing Biogas in Germany


"March 19, 2013 by Redazione

Italy'd better to do the same

by Mara Martini

Germany, that's among the "number ones" in Europe in developing alternative energies and applied technologies, is now focusing its interest on biogas, which it looks in optimistic way at as the most effective green source in order to reduce the CO2 emissions. (Remind the Union has fixed the 20% level by 2020). Among all biomass energy sources, the biogas – coming out from the anaerobic digestion of trash – is infact the most useful one, and the most respectful towards the environment. Turning part of the fields that compose the widest Germanic plain into plant for biogas would permit to obtain: new clean energies, the thermal one (by means of the combustion in boiler) and electric one (through  cogeneration groups); and more, the Digestate – another “output” of digesters, which represents a very good organic phertylizer for cultivated fields. For completing this virtuous circle, the plant could then be fueled by the energy produced by biogas itself. Other very advantageous externalities deriving from biogas plants could be: creation of new jobs and  revaluation of farmers' estates.

Germany’s energy reform

Partilhado por um colega do nosso curso, vamos começar a divulgar alguns artigos do jornal The Economist.
 
 
"LIKE many German regions, northern Saxony around Leipzig is humming with the word Energiewende. Literally “energy turn”, it could also mean “energy revolution”. And that is how Germany sees the twin goals it has set itself: to shut down nuclear power generation by 2022 and to get 80% of its power from renewable sources by 2050.

Energia Solar em França/Espanha/Alemanha

Notícias referencidas no blog "Solar-FCUL":

France launches rescue plan for solar power industry  
1) "France has doubled its capacity target for photovoltaic power generation and offered more financial support to small solar power farms that use European-made panels in a bid to rescue the country's ailing solar industry. Energy Minister Delphine Batho announced the measures, which are expected to spur investments worth more than 2 billion euros ($2.6 billion), during a visit to a solar panel factory in Western France. (...)" (Reuters)

PV, CSP supply 4.3% of Spanish electricity generation in 2012
2) "The Electricity Network of Spain (REE) reports that solar photovoltaic (PV) technology supplied 3.0% of electricity generated in the nation over the course of 2012, with an additional 1.3% supplied by concentrating solar power (CSP). (...) " (Solar Server)

 
Germany Added Record Solar Panels in 2012 Even as Subsidies Cut
3) "Renewable-energy developers in Germany, the world’s biggest solar market, added a record number of panels last year even after subsidies were cut back. Solar installations climbed to 7,634 megawatts, up 2 percent from 7,485 megawatts in 2011, according to figures from the Bundesnetzagentur grid regulator and the Environment Ministry. That was more than double the government’s maximum target of 3,500 megawatts. (...)" (Bloomberg)

"German PV output covered 6.1% of electricity demand in the first nine months of 2012"

Retirado do blog Solar-FCUL:

"BDEW German Energy Blog
According to the latest figures by the Federal Association of the Energy and Water Industry (BDEW) for January to September 2012, solar power generation increased by 50% year-on-year. Renewables contributed 26% to electricity consumption in the first nine months of this year. (...) Wind energy remained the largest contributor of renewable energy in the first three quarters, accounting for 8.6% (2011: 8.0%), followed by photovoltaics accounting for 6.1% (4.1) and energy from biomass with 5.8% (2011: 5.4%). Hydro power contributed 3.8% (2011: 3.3%) and power from waste incineration plants and other renewable energies accounted for an unchanged share of 0.9%."

"“Cidade Solar” na Alemanha produz 4 vezes a energia que consome"

Um conceito diferente, pioneiro e que merece ser divulgado.

Retirado do blog Arquitetura Sustentável:
"Ultimamente, Sonnenschiff, bairro alemão localizados na cidade de Freiburg, na Alemanha tem sido pioneiro no que diz respeito a arquitetura sustentável. A “cidade solar” realiza sua mais nova façanha através de um sistema de captação de energia solar inteligente em todos os telhados das casa apontando para a direção onde o sol pode ser melhor aproveitado. A iniciativa que parece simples, se tornou marca do lugar, sendo usado como rótulo, fazendo novas pessoas instalarem os painéis também.
Projetada por Rolf Disch, o  Sonnenschiff enfatiza a produção de energia de forma eficiente e sustentável com a incorporação das grandes placas solares inteligentes funcionando como toldos. Os edifícios não ficam de fora, também são construídos sob os mesmos padrões e podem gerar até quatro vezes toda a energia que consomem.
