According to a new report there really is no obstacles for a completely renewable electricity production.
CEO of the Swedish Windenergy says:
”There are good prospects for a renewable electricity system. But it requires thoughtful efforts to have it done in a cost effective manner. The grid needs to be refurbished and strengthened and trading capacity with our neighbor cuntries increase. It requires investment in ”smart grid” that will enable all consumers to become more active in the electricity market, while providing new opportunities to manage the renewable electricity fluctuations.”
