A decrease of energy by 90 percent means that only 10 percent of the original energy remains. For example, if you start with 100 joules of energy, a 90 percent decrease would result in just 10 joules remaining. This significant reduction can occur in various contexts, such as in physical systems, energy consumption, or even in the decay of radioactive materials.
