Utility basically measures one's preferences.

	The concept of utility can be compared to how useful something is, ~~a family~~ of ~~6 might choose to purchase~~ a ~~minivan as opposed~~ to ~~a car as it is~~ more ~~"useful" to them because~~ of ~~the large space within the vehicle~~. ~~When comparing one minivan~~ to ~~another there are more subtle reasons why~~ the ~~family might find one model more useful than~~ the ~~other~~, ~~maybe it is heated seats or a certain type~~ of ~~stereo~~.		The concept of utility is used to simplify the assumptions made about consumers, because everybody has different preferences and it is impossible to measure how useful a good is to each unique individual. Determining how much utility a good or service yields to a person helps to determine how the [[demand]] is affected in a [[market]]. Essentially, why a person wants a good or service.

Available: https://commons.wikimedia.org/wiki/File:Issac_St_Claude_Bywater_Power_Line_Workers.JPG</ref>]]The concept of utility can be compared to how useful something is, and the ''reliability of [[electricity]]'' impacts the usability of many services. Reliable electricity provides a consistent ability to heat homes, run hospitals, use the internet, and more. Unreliable electricity causes dramatic drops in utility.<ref>U.S. Department of Energy (2013). (Accessed June 9, 2026). ''Economic Benefits of Increasing Electric Grid Resilience to Weather Outages'' [Online]. Available: https://www.energy.gov/sites/prod/files/2013/08/f2/Grid%20Resiliency%20Report_FINAL.pdf</ref> For example, a fridge can only provide utility if the electricity powering it is continuous, if not the food will spoil. Individuals derive utility from energy services, and reliability increases the expected utility of consumption.

	The ~~concept~~ of ~~utility is used~~ to ~~simplify the assumptions made about consumers~~, because everybody has different preferences it is impossible to measure how useful a good is to each individual. Determining how much utility a good or service yields to a person helps to determine how the [[~~demand~~]] ~~is affected in a~~ [[~~market~~]], ~~essentially~~, ~~why~~ a ~~person wants~~ a ~~good or service~~.		Utility is affected by risk and uncertainty. The risk of power shortages or price spikes due to geopolitical risks, [[supply]] chain disruptions, or [[extreme weather events]] cause reduced utility of energy services.<ref>IEA (2026).

	===~~Marginal Utility~~===		=== Externalities ===
	~~This refers to~~ the ~~additional unit~~ of utility ~~brought by~~ the ~~consumption~~ of ~~an additional unit of a good or service~~.<ref>A. ~~Goolsbee~~, ~~S. Levitt and C. Syverson~~. ''~~Microeconomics~~''. ~~New York~~: ~~Worth Publishers, 2013,pp~~. ~~114~~.</ref> ~~This is particularly important when examining the behavior and preferences of a consumer, for~~ example, ~~the more a good is consumed~~, ~~the less utility~~ it ~~yields. This effect is known as '''diminishing marginal~~ utility~~'''~~.		Pollution is an [[externality]] that results in negative utility. [[Air pollution]], [[Greenhouse gas\|greenhouse gases]], and water contamination create negative utility: health impacts, agricultural productivity, property damage, and generally environmental change.<ref>Sustainability Directory (2025). (Accessed June 9, 2026). ''How Are the “Negative Externality” Costs of Fossil Fuels Calculated?'' [Online]. Available: https://energy.sustainability-directory.com/learn/how-are-the-negative-externality-costs-of-fossil-fuels-calculated/</ref> These harmful side effects are negative externalities that reduce social utility, known as the Social Cost of Carbon (SCC).<ref>Stanford Report (2021). (Accessed June 9, 2026). ''Stanford explainer: Social cost of carbon'' [Online]. Available: https://news.stanford.edu/stories/2021/06/professors-explain-social-cost-carbon</ref> For example, while cheap coal power grants lower electricity bills (positive utility), it also worsens health and lowers quality of life (negative utility).

	~~For example~~, if a ~~single person buys a car then they are able to get around the city quickly~~ and ~~efficiently~~, ~~saving them time~~. If that ~~same person buys a second car~~ of ~~a similar model~~, ~~it has less utility~~ or ~~usefulness to that person because they can only drive one car~~ at ~~a time and can~~'t use it ~~for a different purpose~~.		=== [[Cost]] ===
			The consumer's choice depends on what they can ''afford'', known as a budget constraint. Money that an individual spends on one good is not available for other goods and services.<ref>Oregon State University (2026). (Accessed June 9, 2026). ''Budget Constraints'' [Online]. Available: https://open.oregonstate.education/intermediatemicroeconomics/chapter/module-3/</ref> This means that spending more money on your electricity bill results in less available money for everything else, effectively reducing the purchasing power of the consumer. This forces the individual to decide on ''tradeoffs'' (reallocating their spending).<ref>OpenStax (2025). (Accessed June 9, 2026). ''6.2: How Changes in Income and Prices Affect Consumption Choices'' [Online]. Available: https://socialsci.libretexts.org/Bookshelves/Economics/Microeconomics/Principles_of_Microeconomics_3e_%28OpenStax%29/06%3A_Consumer_Choices/6.02%3A_How_Changes_in_Income_and_Prices_Affect_Consumption_Choices</ref> As an example, rising household energy prices may force consumers to either reduce other essential spending or live at uncomfortable temperatures.<ref>Statistics Canada (2023). (Accessed June 9, 2026). ''Canadian Social Survey: Energy use'' [Online]. Available: https://www150.statcan.gc.ca/n1/daily-quotidien/231030/dq231030b-eng.htm</ref> The utility of a good/service may be indirectly affected by its cost, because it may impact the ability to buy other essentials.

	==~~Also See~~==		== Marginal Utility ==
			This refers to the additional utility brought by the ''consumption of one additional unit'' of a good or service.<ref>A. Goolsbee, S. Levitt and C. Syverson. ''Microeconomics''. New York: Worth Publishers, 2013,pp. 114.</ref> This is particularly important when examining the behavior and preferences of a consumer. Generally, the more a good is consumed, the less utility it yields. This effect is known as '''diminishing marginal utility'''.

			Figure 2 features a graph with two patterns. Total utility: shows how '''total satisfaction''' increases with additional units, but slows down and eventually reaches a maximum. Marginal utility: represents the '''extra satisfaction''' gained from each '''additional unit''', which is a clear downward trend as each additional unit yields less satisfaction. [[File:UtilityQuantified.svg.png\|thumb\|600x600px\|Figure 2. Comparing total utility and marginal utility.<ref>Wikimedia Commons (2008). (Accessed June 9, 2026). ''UtilityQuantified'' [Online]. Available: https://commons.wikimedia.org/wiki/File:UtilityQuantified.svg</ref>\|center]]An example of diminishing marginal utility would be, if a single person buys a car. Buying a car allows the individual to get around the city quickly and efficiently, saving them time. If that same person buys a second car of a similar model, it has less utility or usefulness to that person. The second car is less useful because they can only drive one car at a time, therefore the second car doesn't give them the same amount of utility as the initial car did.
