In short, goals help organizations to achieve a variety of ends—including the reduction of energy waste.
Energy efficiency improvement goals, also known as energy efficiency targets, are intended reductions in energy over a specified time frame that have been defined in a SMART manner. Targets are useful because they can encourage decision makers to improve the use of energy in their communities and operations.

Cities should explore both mandatory public sector targets and voluntary private sector targets to forge energy-efficient communities.

shopping_list=("codelab", "textbook", "ipod", "cd", "bike")
prices={"codelab":300, "textbook":100,"ipod":50, "cd":10, "bike":600}
number_of_items=0
sum=0
for index in range(len(shopping_list)):
sum=sum+prices[shopping_list[index]]
if (sum<=budget):
number_of_items=number_of_items+1
else :
break
print "number of items you can purchase, for a budget of",budget,"is",number_of_items
Explanation:
A code to determine the number of items that can be purchased is above, given the value associated with budget, and given that you will buy items in the order that they appear in the tuple associated with shopping_list.
