Some mesetto ago gianlkr outlined the problem to install photovoltaic panels in condominium. Well Japan comes the future solution (gianlkr unfortunately have to wait a few annetto): photovoltaic leaves. He designed the National Institute of Advanced Industrial Science and Technology (AIST) with Mitsubishi Corp.. and Tokki Corp..

It will be required to install photovoltaic panels on the roofs in the German town of Marburg, 80,000 souls north of Frankfurt. In addition to incentives, to push on renewable with effect from 1 October 2008 required owners to install just puts hand to the roof for any work: new buildings obviously will have to mount them mandatory.

He established the municipal coalition of Social Democrats and Green imposing fines of over 1,000 euros to those who will not later. According to calculations, enough for 15 years amortize investments of at least one solar panel every 20 square metres of roof.

There are discussions policies: there are those who argued that the measure will trend and soon will be copied in other cities while there is the Christian Democrats speak of dictatorship environmentalist. In Italy, the 2008 budget already speaks of “mandatory installations” but not specifically mentions the obligation to install them in every work of maintenance for buildings (both for individuals and for businesses). A system of incentives and financing facilitated banks in Germany as in the rest of Europe, is already active to help individuals more reluctant to digest these new charges.

He was inaugurated last Wednesday, the first idrogenodotto underground for urban areas of the world: the presence of the President of the Region Tuscany, goldsmith in the industrial area of San Zeno around Arezzo were opened the taps to businesses and homes in the area that could use the ‘Hydrogen produced locally through photovoltaics.

A project co-financed by private institutions and local policies: Region Tuscany, City and County of Arezzo, Group Sapio, Exergy Fuel Cells and Cooperativa del Sol have signed the agreement four years ago, investing about one million euros. Today showed that the widespread diffusion of hydrogen, although it has cost more than other renewables (see the ‘wind and photovoltaics) is still strongly supported by Jeremy Rifkin precisely because it can be produced virtually anywhere.

The idrogenodotto is a meter and twenty centimeters wide and traporta pure hydrogen to 42 companies and all’HydroLab, the laboratory demonstration devoted to renewable energies, where they were placed two fuel cells from 1Kw and with a photovoltaic system for production of renewable hydrogen from water through electrolysis.

In a few weeks will start the domestic supply which will cut the cost of road transport and storage and above all, will make common Arezzo energy-independent local production of energy and heat will be sufficient to withstand the industrial consumption is domestic with the added advantage of decoupling these areas from oil and gas. Sustainable economic growth therefore, is sganciabile policies of oil lobbies.
