==Supply==

<onlyinclude>'''Supply''' is: "the quantity of a good or service that producers are willing to provide at the specified price, time period, and condition of sale".</onlyinclude><ref>C. Park. "Supply." [Online], Available: http://www.oxfordreference.com/view/10.1093/acref/9780198609957.001.0001/acref-9780198609957-e-7987?rskey=ER6mri&result=1, 2012 [Sep 3, 2016].</ref>

The supply side of a market is influenced by a number of factors, price helps determine how much will be produced, if a price is high then producers will produce more of a good to take advantage of high prices. Conversely, if prices are low then producers will be discouraged from producing a large quantity of the good.<ref name=goo/>

The price of what goes into manufacturing a good (production [[cost]]) and the technology used also affect the supply. If a manufacturer is producing [[photovoltaic cell| solar panels]] at a cost of $35 per unit and over time new [[semiconductor]] manufacturing technology is developed making them cheaper to produce, then the overall price will fall and the producer will be able to manufacture a larger quantity.

The number of sellers at a market will also increase the supply, conversely if there are fewer producers, then the supply will drop because one firm cannot produce the same amount as multiple firms without a larger expansion over time.

==Price Changes and the Effect on Supply==
[[File:Supply- Price Effect.png|450px|thumb|right|Figure 1. As the price for a god or service changes, the supply increase or decreases as consumers are willing to buy more or less as the price fluctuates.<ref>Created internally by a member of the Energy Education team</ref>]]

'''Figure 1.''' shows how changes in the price for a product affects the quantity of a good supplied to a market.
*At '''Point A''' the price of the good is '''P1''' and the quantity supplied is '''Q1'''
*There are a number of reasons why the price changes, see [[price]] and [[demand]], but some factor causes the price in the market to change.
*If the price for the good falls to '''P3''' then the quantity supplied will also decrease to '''Q2'''. This is '''Point C''' on the supply curve.
*If the price for the good rises to '''P2''' then the quantity supplied will also increase to '''Q2'''. This is '''Point B''' on the supply curve.

==Shifts in Supply==
[[File:Supply- Shifts.png|450px|thumb|right|Figure 2. Factors that cause shifts in supply to a market change the total quantity that is available in a market.<ref>Created internally by a member of the Energy Education team</ref>]]

Factors that "shift" the supply in a market are factors other than price. For example, if an advancement in technology makes it cheaper to produce a good or service than the supply will increase because it is cheaper to produce.<ref>D. Besanko and R. Braeutigam. ''Microeconomics''. Hoboken: Wiley, 2011, pp. 61-63.</ref>

Another factor could cause the supply to shift and decrease the supply to the market. For example, I the cost of production rises because raw materials are more expensive then the quantity supplied will be less because the product is more expensive to produce.

Shifts affect the '''total quantity (TQ)''' supplied to a market. See how shifts affect the market in '''Figure 2.'''
*The total supply for '''S1''' is '''TQ1''', the maximum amount of the good that could be supplied to the market is '''TQ1'''.
*If a factor causes a shift that increases the supply to '''S2''' then the total quantity available is '''TQ2'''.
*Another increase would result in an increase to '''TQ3'''

If the demand for the good is more than '''TQ3''' then there will be a shortage as there is not enough of the good to satisfy every consumer that wants it.

For example, during the [[Oil crisis of the 1970s]] there was not enough [[gasoline]] for every consumer who wanted it. In that case, the demand for gasoline exceeded or outstripped the supply of gasoline.

===Supply Choke Point===
The '''supply choke point''' is the price below which, the producer will not sell their good. The supply choke point is where the supply curve intersects the Y-axis. Assume that the supply of a good in a market is '''S2''' in '''Figure 2.''' The supply choke point is '''P2''', the firm will not sell the good for any price below that point.<ref>A. Goolsbee, S. Levitt and C. Syverson. ''Microeconomics''. New York: Worth Publishers, 2013, pp. 24.</ref>
