The demand for energy is increasing worldwide, and using renewable energy is widely considered to be a pragmatic solution to meet the demand in cities and transportation systems. However, the ability of sustainable energy sources to replace conventional energy is thought to be limited due to a number of technical and financial issues. While I agree that design complexity and high capital cost may impose some restrictions, I believe that alternative energy sources will play a key role in supplying cities’ essential services in the foreseeable future. Analyzing the ability of sustainable energy to both provide a clean energy and protect the environment will show this.
