Summary Section

Problem Summary

High energy costs in Washington D.C have caused the average utility bill to be USD 18.93 per kWh above the national average of USD 17.01 per kWh. Additionally, aging infrastructure has negatively impacted carbon emissions. As a result, these issues have substantially increased the cost of living for residential homeowners and decreased efforts for sustainable housing development by the government.

Solution Summary

Our solution is to reduce high electricity costs in Georgetown by implementing energy efficiency retrofits (LED lighting, insulation, smart thermostats) and facilitating participation in community solar programs. This solution would be technically feasible by using proven technologies that can be installed quickly by DCSEU-approved contractors. Financial viability is ensured through DCSEU incentives, DOEE, and DC Green Bank financing, reducing upfront costs for homeowners and developers. Utility companies benefit from reduced grid strain and potential revenue from community solar, while homeowners gain immediate bill savings. This approach is socially acceptable and equitable, targeting vulnerable populations most impacted by high energy costs. It aligns with DC’s sustainability goals by lowering emissions. Contractors also benefit from new business opportunities. Overall, the project is a win-win for stakeholders, combining environmental, social, and economic sustainability into a scalable model for affordable energy solutions.

Practical Humility Clause

Due to time requirements to explore more detailed factors related to key measures, policies, regulations, and data accuracy, we had to make estimations and assumptions:

  1. Homeowners are willing and able to participate in energy efficiency upgrades.
  2. Homeowners and contractors are eligible to apply to financial and technical grants.
  3. Estimated savings (in electricity and its related costs) from LED, insulation, and smart thermostats are consistent across different home types.
  4. Availability of DCSEU-approved contractors with the capacity to implement upgrades in the target neighbourhoods.
  5. Long-term policy incentives remain in place.

Further Explanation Section

To ensure the affordability of implementing retrofits, several key funding programs can be used to support affordable housing. These funding programs are crucial for lowering the upfront cost of retrofits as 30% of homeowner income is spent on housing and energy. By leveraging these funding programs, utility bills can be reduced for low- and moderate-income residents while achieving government sustainable development goals 7 and 11 for renewable energy and sustainable communities.
