1. The two solutions being proposed for the chosen sub-problem. 2. A description of how the sub-problem can be solved, and the rationale and research supporting each solution. 3. An explanation of how prioritization was involved in designing each solution. 4. An explanation of how both solutions to the sub-problem play a role in solving the larger problem. 5. A finalized citation page of the sources (at least three) you used for research, following the MLA style guide.Adescription of your complex realworld problem, and an explanation about why you chose this problem. Problem: Reducing energy consumption in urban areas Description: Urban areas consume a large amount of energy due to the high concentration of buildings and infrastructure. This energy consumption contributes to high carbon emissions and an increased risk of climate change. Therefore, it is important to find ways to reduce energy consumption in urban areas. A minimum of two sub-problems that are more manageable and solvable. 0 Improving building energy efficiency 0 Increasing the use of renewable energy sources in urban areas An explanation of how these sub-problems came about and are related to or a direct result of the overall problem. Improving building energy efficiency is a sub-problem as buildings are significant energy consumers in urban areas. Increasing the use of renewable energy sources in urban areas is another subproblem as it can help reduce the reliance on nonrenewable energy sources and reduce carbon emissions. A description of how solutions to these problems connect with each other in solving the overall problem. Improving building energy efficiency can help reduce the amount of energy consumed by buildings, which in turn reduces the overall energy consumption in urban areas. Increasing the use of renewable energy sources in urban areas helps to reduce the reliance on non-renewable energy sources and decrease carbon emissions, further reducing energy consumption in urban areas. . A list of at least three sources you will use for research. These do not have to be in a particular format. 0 United Nations Environment Programme (UNEP) o International Energy Agency (IEA) 0 US Department of Energy
