Care of the environment and natural resources such as water holding important way for energy conservation with case studies on cities

theenergy to treat and distribute potable water supplies.The energy intensity of Denver’s waterincluding supplying water and treating wastewater is 821 kWh/AF. Parker Water andSanitation, in contrast, uses asubstantial amount of energy to pump groundwater fromDenver Basin aquifers. The energy intensity of water in Parker averages 4,494 kWh/AF –groundwater pumped from deeper portions of the aquifer is even more energy intensive. Importantly, new watersupplies that Front Range cities hope to develop will be more energyintensive than existing supplies. Groundwater pumped from greater depths, surface waterconveyed over longer distances, and water treated to higher standards (i.e. using UV radiation)will all require more energy than today’s water supplies.Water conservation, in contrast, can provide significant energy savings, while saving customersmoney and reducing the State’s greenhouse gas emissions.
