As growth regions evolve to accommodate the increasing population, they need to develop a wider variety of residential properties to accommodate the varying needs of the residents. As a result, the new accommodation is denser which involves higher embodied water carbon and energy. This research compares the construction differences in metropolitan and growth regions of Melbourne to identify embodied carbon, water, and energy. Representative areas of 25 km2 are selected from both regions. The growth region has 80% of the built area comprised of 2nd generation low-rise residential buildings whereas the prolific construction type in the Metropolitan region is mixed purpose industrial with 30% of the built area comprising of this type. The methodology implies open-source satellite imagery to build a spatial dataset in QGIS. The visual identification of the constructions in the study areas enables to identity the materials used in their construction. The total embodied carbon, water, and energy for the Metropolitan region are 32,895 tonnes, 4192 mL, and 3,694,412 GJ, respectively, whereas in the growth region, the totals are 179,376 tonnes carbon, 2533 mL water, and 2,243,571 GJ. Whilst Metropolitan has a significantly higher overall footprint when this is compared to the population of each region, it is shown that the growth region with its current construction type has a higher embodied carbon, water, and energy per head. The total per head for Metropolitan is 226.7 GJ energy, 257 kL water, and 20 tonnes carbon, whereas in the growth region, the embodied energy, water, and carbon, respectively, per head is 287.4 GJ, 324.6 kL, and 22 tonnes. The current performance per head of the growth region is considerably lower than that of Metropolitan. Using diverse residential construction types and efficient materials can serve the demanding needs of denser populated areas.

“…The use of water covers all stages of the fuel cycle, from extraction of energy resources such as oil and natural gas, to energy production and electricity generation [13] , [14] . Electricity is needed for extraction, conveying, purification, and transfer of the water to different forms of consumers in the economy [12] , [15] , [16] . It is considered the major water consumer of all energy types and accounts for 25%−80% of the water used for energy generation [17] , [18] .…”

“…In India, the coal-based power plant is a major source of electricity generation which accounts for 58.8% of total power production than any other sources of power generation and requires an intensive amount of water to generate electricity at different stages of power production (Wang et al, 2019). The total sector-wise consumption of electricity is expected to increase to about 4500 billion kilowatt hours (kWh) by 2031-2032 that will lead to an increase in total installed capacity to around 800 gigawatt (GW) by 2030 (Garg, 2012).…”

“…Investigations made available to assessed water use for various sources (coal, gas, nuclear, etc.) of electricity generation (Grubert et al, 2012;Wang et al, 2019) focused on water withdrawal and consumption based on the power generation technologies like supercritical, subcritical, IGCC, and other various technologies (Macknick et al, 2012;Meldrum et al, 2013). A review of a previous study highlighted that thermal power plants use intensive water for cooling purposes compared to water usage in power generation through other technologies like solar photovoltaic (PV) and wind turbines (Qin et al, 2015).…”

the total water supply to the sector was withdrawn by power plants. Further, the study assessed its tradeoff with other sectoral water demand adopting WSI (Water Stress Index) criteria for both surface and groundwater sources. The results highlighted the per capita groundwater to be under severe stress and similar status was also identified in the case of fresh surface water except for the Central region. The overall WSI status was found to be severe in all regions of India. This situation creates a water-scarce situation for water-guzzling power plants that are dependent on surface water and faces the competitive situation with the agriculture and domestic sector. Results of the study concluded that the technological up-gradation at the power plants could be helpful to reduce the total water demand by 78% of coal power sector which can be reduced the severity of regional water stress. Our study aids policymakers to identify the region which is more vulnerable in terms of crosssectoral water demand and also fulfills the need for quality data availability at a regional scale that may use in the future towards sustainable water-resources management practices.
