As an expert in renewable energy, I am well-versed in the various aspects of energy production, including the costs associated with different sources. Tidal energy is an intriguing form of renewable energy that harnesses the power of the ocean's tides to generate electricity. The cost of tidal energy per kilowatt-hour (kWh) can vary significantly depending on a multitude of factors, including the technology used, the location of the project, the scale of the installation, and the local economic and regulatory environment.

The cost of tidal energy is influenced by the capital costs associated with the construction of tidal energy facilities, which include the cost of the turbines, the underwater infrastructure, and the grid connection. Maintenance and operational costs are also significant, as the equipment must be able to withstand harsh marine conditions. Additionally, the cost of energy production can be affected by the efficiency of the turbines and the predictability of the tides, which can impact the overall output and, consequently, the cost per kWh.

It's important to note that the cost of tidal energy has been decreasing over time as technology advances and projects become more economically viable. The study you mentioned, which concluded that tidal power could produce electricity for 4.2 to 6.5 cents per kWh, is a valuable insight into the potential cost-effectiveness of tidal energy. This is particularly noteworthy when compared to the standard offer for Central Maine Power customers, which is 8.4 cents per kWh. Such a comparison highlights the competitive edge that tidal energy could have in certain regions.

However, it's crucial to consider that the cost of tidal energy can also be influenced by external factors such as government subsidies, which can significantly reduce the cost of production. Additionally, the environmental impact and the social acceptance of tidal energy projects in local communities are also important considerations that can affect the overall cost.

In summary, while the cost of tidal energy per kWh can be competitive with other forms of energy production, it is essential to take into account the specific circumstances of each project. The future of tidal energy looks promising, with ongoing research and development aimed at further reducing costs and improving efficiency.
