This analysis will cover four key dimensions to differentiate between the solution present and our solution. Each solution will be rated on a scale from 1 (does not meet the criteria) to 5 (fully meets the criteria). Any numbers for the cost are in the Cost Analysis page.

Technical Feasibility

1. Infrastructure: Is there sufficient infrastructure to support the proposed solution?
2. Technology readiness: Are the required technologies mature and available?
3. Local capacity: Do local organizations or governments have the technical expertise to implement and maintain the solution?

Technical Assessment Table

The gas-powered buses are already in use in this country, which means the technical feasibility is currently more favorable for gas or diesel buses. However, there is also potential to transition from fossil fuels to biofuels which is our solution. This type of gas is already being used in some Brazilian cities. Porto Alegre could explore a partnership or contract to implement this solution.

As for electric buses, which is in our solution proposal, the city would need to invest in additional infrastructure and develop local expertise before large-scale deployment. More research and preparation are required to ensure a successful transition.

Economic Feasibility

1. Initial costs: What are the investment requirements (e.g., cost of new buses, infrastructure upgrades)?
2. Long-term savings: Will operational savings (e.g., fuel, maintenance) offset the initial investment over time?
3. Funding sources: Are there available grants, government programs, or international funds to support the project?

Economic Assessment Table

New solution received the highest score in this analysis despite their higher upfront cost, because they represent a long-term sustainable solution. The annual charging cost is lower, especially considering that Porto Alegre’s main energy sources are hydro and solar power, which are government-regulated to keep prices stable and support the national economy. Additionally, this option benefits from international funding programs, such as those offered by the IEA.

On the other hand, present solution scored the lowest. Although they have a lower initial purchase price, they do not receive government subsidies or international funding and have higher operational costs over time.
