Essay Abstract: 
Threatened by climate change, global energy systems need to align with the clean energy transition. The current portfolio relies heavily on carbon-based fossil fuels and lacks renewable options. Embracing new forms such as in-stream tidal energy is crucial. However, tidal energy faces limitations due to the scarcity of suitable locations. This thesis examines nine East Coast locations in the US to assess their power production potential. To determine suitability, the model considers tidal variation and discharge data. It calculates two variables at half hour intervals: hydrologic flow (uh) and upriver tidal wave (ut). Combining these values yields water velocity, which determines power output using the hydrokinetic turbine power equation. Out of the nine locations, seven were able to generate power. However, only 5 produced over 1 megawatt hour per week, sufficient to meet the energy needs of 750 homes simultaneously. This assessment expands the range of renewable energy options available for the global energy portfolio. In conclusion, the urgency to combat climate change demands a shift towards clean energy. In-stream tidal energy presents a promising alternative. By assessing and identifying suitable locations, this study contributes to expanding the utilization of tidal energy, enhancing the diversification of renewable energy sources.
