2.  Article Summary:  Frigid temperatures are contributing to soaring demand for propane, kicking off a surge in prices and a scramble to get the liquid gas used in agriculture and home heating to parts of the Midwest and South. The article reports that not only an increase in demand but also a decrease in supply has caused record-setting propane prices. “Issues such as maintenance on a major pipeline during November and December, as well as rail disruptions, kept propane supplies in the Midwest from being replenished in time for the cold weather, after farmers used more of it than usual to dry crops after a wet harvest, said T. Mason Hamilton, an analyst at the U.S. Energy Information Administration.” The article notes that consumers are adjusting to the higher propane prices for example by turning down their thermostats.

3.  Class Concept:  Supply and Demand

4.  According the article the demand for propane has increase. This creates a rightward shift in the demand curve.  The supply has also decreased causing a leftward shift in the supply curve.  When demand increases and supply decreases prices will definitely rise.
