What did the people a long time ago use for energy?

Answer 1

A long time ago, people primarily relied on natural sources for energy. They used wood for fuel and heating, harnessed the power of wind for sailing, and utilized water for milling grain. Additionally, human and animal labor provided energy for various tasks, while early civilizations began to explore the use of coal and other fossil fuels as they progressed. These methods laid the foundation for the energy systems we utilize today.
