The wind potential in Romania

A wrong solar map of Roamania

The solar potential in Romania . An improve one.

A more exact map of solar irradiation

Investment efficciency balance between wind and photovoltaic.

Romanian case.

Study case:3 milion euro investment fund

A private look and a state look.

Cazul parcului Fotovoltaic (200ha)de la Cluj Napoca

Photovoltaic world - senior PV market analyst Sam Wilkinson:

After two years of solid growth, demand has softened and PV modules are

being priced highly competitively as a result,he writes in a report: "We've seen modules

from recognized brands being offered for less than $1.45/W (~€1.02).“

30th June 2011

P.Solar Cluj Napoca (200ha) with brand solar equipment

P.Solar Cluj Napoca (200ha) with cheap solar equipments

P.Solar Cluj Napoca (200ha) with cheap equipment and inflation correction

Cluj Napoca photovoltaic parc (200ha)

Only a very good incentives?Or a “political” affair?

DANEMARCAUniv. Aalborg planifica energetic Danemarcaanului 2050 – care va fi 100% pe regenerabile

ROMANIAPoliticieni iau decizia “lautareste” – ca sa-l citezpe C.Noica, nu sunt interesati profesionisti

DIFFERENT RENEWABLE ABORDATIONS

EFFICIENCY is the key of energy
