TR.ENERGY is an innovative energy delegation mechanism in the TRON ecosystem designed to optimize resource usage and increase transaction efficiency. In the traditional TRON model, users must freeze TRX to obtain the energy needed to complete transactions. This often leads to inefficiency, especially for users with low transaction volume who have to keep a significant amount of TRX frozen to avoid bandwidth and energy fees

TR.ENERGY solves this problem by allowing users to delegate their energy to other accounts. This means that users who don't need all their energy can rent it out to those who need it, thereby creating an energy market. This market facilitates more efficient resource allocation, as users can earn income from their unused energy, and others can access energy without having to freeze TRX.
