Additional EROEI Calculations

There are three prominent expanded EROEI calculations, they are point of use, extended and societal. Point of Use EROI expands the calculation to include the cost of refining and transporting the fuel during the refining process. Since this expands the bounds of the calculation to include more production process EROEI will decrease. ^[1]Extended EROI includes point of use expansions as well as including the cost of creating the infrastructure needed for transportation of the energy or fuel once refined. ^[2] Societal EROI is a sum of all the EROIs of all the fuels used in a society or nation. A societal EROI has never been calculated and researchers believe it may currently be impossible to know all variables necessary to complete the calculation, but attempted estimates have been made for some nations. Calculations done by summing all of the EROEIs for domestically produced and imported fuels and comparing the result to the Human Development Index (HDI), a tool often used to understand well-being in a society ^[3]. According to this calculation, the amount of energy a society has available to them increases the quality of life for the people living in that country and countries with less energy available also have a harder time satisfying citizens’ basic needs. ^[4] This is to say that societal EROI and overall quality of life are very closely linked.

Extras for general article improvement: 1. change equation picture- the one from my review is in more basic language. I think the entire article is too technical but addressing the technicality of this is a good start for understandability. 2. add cutoff- A fuel or energy must have an EROEI of at least 3:1 to be considered viable for society. ^[5] 3. EROI used to advocate for fossil fuels because their EROI is highest but it has been falling. 4. I have posted on the talk page about reducing the technicality of the language in some places since this is article scored poorly on the readability website we were given. This will mean re-writing some wordy sentences or changing vocab slightly.
