The invention discloses high-energy and environment-friendly renewable clean fuel and a preparation method thereof, and belongs to the technical field of a new energy source fuel. The high-energy and environment-friendly renewable clean fuel is prepared from the following raw materials by mass percent: 65.43% of methanol, 30.5% of auxiliary material, 3.3% of denaturing agent, 0.57% of dissolving-assisting and pungent-increasing additive, and 0.2% of dispersant. The high-energy and environment-friendly renewable clean fuel produced by the method disclosed by the invention has the significant progresses that 1, the traditional fuel can be fully and comprehensively replaced, and the realistic problem of crisis of global energy can be solved; 2, the high-energy and environment-friendly renewable clean fuel is wide in raw material range, and free of emission of three wastes in the production process; 2, the high-energy and environment-friendly renewable clean fuel is broad in applicable range, and the operating requirements of kinds of fields such as industries and the like can be met; 4, the consumption is lower than that of the traditional fuel under the same condition, the environmental index is that over 80% of emission is reduced in comparison with the traditional fuel, and energy conservation and emission reduction are really achieved; 5, the high-energy and environment-friendly renewable clean fuel is high in cost performance, and the price of the product does not change along with fluctuation of the international crude oil price, and is stable; and 6, the high-energy and environment-friendly renewable clean fuel is high in safety performance.
