%X Life cycle energy consumption, environmental impacts, and economics of coal and straw briquettes were studied using hybrid life cycle analysis (LCA). Energy return ratio, resource depletion index, environment impact load and life cycle cost were considered in the analysis. To balance energy, environmental and economic indicators, EEE (Energy, Environment, and Economics) indicators were adopted as a combined indicator to evaluate coal and straw briquettes. For the whole life cycle, the energy return ratio and resource depletion index of straw briquettes were lower than coal. Straw briquettes also had lower potential for global warming, acidification, eutrophication, smoke and dust, and solid waste production. The EEE indicator of straw briquettes was 79.8% lower than coal. Thus, the environment impact load for straw briquettes is low, and straw briquettes have the potential to displace coal, taking the energy, environmental and economic aspects into consideration. However, the life cycle cost of straw briquettes is slightly higher than coal, so the extended application of straw briquettes needs the financial support of the government.
