1 The Department of Energy finds that â Among a large sample of wind projects installed in 2012, the capacity-weighted average installed cost stood at nearly $1,940/kW, down almost $200/kW from the reported average cost in 2011 and down almost $300/kW from the reported average cost in both 2009 and 2010 .â [3].he Department of Energy, below, depicts the cost reduction in wind energy alongside U.S. wind energy deployment, showing a decrease in cost of more than 90% since the early 1980's.
As noted by MDGuidelines, the majority of fractures to the sternum heal in six to 12 weeks without the need for medical intervention.

Bruised ribs indicate an injury to the muscles surrounding the ribs rather than the ribs themselves. Bruised ribs heal on their own, and only small measures to promote healing can be undertaken. They take about 3-6 weeks to heal completely.ruised ribs are different from broken or cracked ribs in a way that in broken ribs the injury is directly inflicted upon the bone, while in bruised ribs the surrounding muscle area is affected. Bruised ribs are not as dangerous as broken ribs because broken ribs can injure the heart and lungs.
