Can the United Kingdom's tidal energy assist in reducing reliance on fossil fuels?

The UK's tides have the potential to reduce reliance on fossil fuels and contribute to renewable energy sources. Tidal power, which is abundant in the UK due to its powerful tides, remains largely untapped. However, British companies are leading the way in developing innovative technologies to harness this energy. Unlike wind and solar power, which depend on favorable weather conditions, tidal power is predictable and can provide a constant stream of energy. Studies suggest that tidal power could meet up to 11% of the UK's electricity demand. Tidal power has been used for centuries, with the Woodbridge Tidal Mill in Suffolk using it to mill grain for almost 1,000 years. While the construction of dams and barrages for tidal power generation has environmental consequences, research has shifted towards tidal stream energy. Various devices are being tested in the UK's stormy coastal waters, such as turbines placed on the seafloor and submersible kites that exploit tidal currents. The main challenge lies in the high cost and maintenance difficulties associated with operating in the sea. However, supporters of tidal power believe that as the industry grows, costs will decrease similarly to those seen in wind and solar power. The predictability of tides makes tidal power an attractive alternative to gas-powered plants, which are used to balance intermittent renewable energy sources. The UK government is providing subsidies for tidal energy projects and is committed to purchasing the electricity they produce. While tidal energy does create a minute additional drag on the Earth's rotation, this effect on the length of the day is negligible. Tidal energy is expected to play a significant role in the UK's energy system in the future, benefiting the overall energy landscape.
