According to a study by the investment banking firm Lazard, the cost of utility-scale solar energy is as low as 5.6 cents a kilowatt-hour, and wind is as low as 1.4 cents. In comparison, natural gas comes at 6.1 cents a kilowatt-hour on the low end and coal at 6.6 cents.ccording to a study by the investment banking firm Lazard, the cost of utility-scale solar energy is as low as 5.6 cents a kilowatt-hour, and wind is as low as 1.4 cents.

Steam it out. Similar to drinking hot liquids, the heat and moisture of steam help to break up and dissolve mucus deep in your lungs and throat. Take a hot shower, or fill a bowl with very hot water. Place your face over the bowl and a towel over your head to trap in the steam. This will make it easier to expel. 2  Chest congestion can turn into pneumonia if not taken care of early. 3  See your doctor! 4  There are two places to open palm 'slap;' on either side of the chest to help break up congestion and two on the upper back.
High frequency chest wall oscillation (HFCWO) is an airway clearance technique that loosens mucus by applying vibrations at different frequencies to the chest wall via a wearable vest. How does HFCWO work? HFCWO devices typically consist of an inflatable vest, connected by hoses to an external generator, that delivers percussion to the chest wall. Rapid and repeating pulses of positive air pressure gently oscillate (squeeze and release) the chest to facilitate mucus clearance.
