RE:Heavy VolumeThere's a strong shift into the renewable energy space going on... just look at ICLN, the etf which tracks approximately 100 clean energy-related companies.. it's up over 12% over the past 10 days.. furthermore the cost of conventional sources of energy, oil and gas, continue to increase significantly and according to the respective analysts will most likely continue on their upward trajectory.. this all plays into the case for renewable sources of energy..
