Copenhagen listed Greentech Energy Systems stock continues to impress - from a low of 17.9 in early May, it yesterday closed up at 37.9. Since announcing a Q1 operating profit of DKK 1.50m (USD 0.25m) on May 31st, this company's stock has been consistently improving.

Unusually for a small windfarm developer and operator the company plans significant expansion abroad, namely Italy and Poland.This strategy makes sense because having your windfarms in very diverse locations, hedges the risk of the inherent intermittency in wind power.

Denmark has led the world in its adoption of windpower. It even has the world's largest manufacturer, Vestas, also a listed company.
