Renewable Energy

The Conversion process from Biomasses to electric energy involve a big efficiency loss, and this is why it's better converting them in heating. For thermic energy, we can consider the little plants (30 Kw boilers, i.e.), requiring a small quantity of biomasses but enough to warm a single house.
Also, small quantity of biomasses are competive in cost, because gas oil has higher taxes for domestic use.
Mr. Pari going on "Electric energy is different because every central produces 10/12 Mw at least, so it should burn 10.000 tons of wood for year, with these consequences: high cost for delivery and high cost for biomasses, higher in Italy than in North-Eastern Europe".
Considering big numbers, biomasses are not competitive in Italy because the whole energy production is based on petroleum; "a good alternative should be small central combining the production of electricity and production of heating, but Italian energetic system is basend only on big energetic centrals", said Andrea Masullo, responsible for Energy and Resources for WWF. This why biomasses are not used for electricity, but their heating utilization is growing. In Northern Europe, 95% of farmers use wood or pellets for heating.
