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. Furthermore, MDGuidelines states that in order to avoid setbacks or further injuries, adhering to the recommended treatment method presented by a physician is essential.
In general, small broken bones with simple fractures take about four weeks to heal in small children. In teenagers and adults, small bones â like a finger or wrist bone â with a simple fracture, will take about six weeks to heal. Larger broken bones, for example the bones in the thigh, would take a great deal longer to heal, usually six weeks to three months in the average healthy adult. Compound fractures often require surgical realignment of the bones so that as they heal, they rejoin each other properly.
