Project the estimated reduction in GHGs that will result from the proposed net zero project in years $2008-2010.$Assume for the purposes of your analysis that all equipment upgrades are made immediately at the start of $2008.$

"Based on these past experiences, the resource conservation team expected to achieve a $75\%$reduction in water use, an $80\%$reduction in natural gas consumption, and a $90\%$reduction in purchased electricity. Approximately $80\%$of the reduction in natural gas would come through the substitution of biomass fuels."
