Tidal energy is not renewable as it harms the environment faster than consuming fossil fuels, according to a study. Using tidal energy would cause extreme temperature changes and make life on Earth intolerable. Despite being seen as sustainable, tidal energy poses environmental challenges, including harming the environment. Tidal forces have slowed down both the Earth's and Moon's rotations over time, with the Moon now tidally locked and the Earth's rotation slowing due to friction with the ocean floor. It will take approximately 1 billion years for the Earth's rotational energy to be depleted, causing the planet to lock its rotation to the Moon. However, consuming tidal energy could cause this process to occur in as little as 1000 years. The text covers various topics in energy, physics, and astronomy, including Brownian motion, Crookes radiometers, misconceptions in thermodynamics, Earth's magnetic field, tidal energy, relativity, and the simplest derivation of E = mc2. It also discusses revisions made to the document over time, including new sections and references related to the Earth's rotation and tidal forces.
