Alternative energy sources that use the natural power of the wind waves and sun are too expensive and complicated to replace the coal, oil and gas that we use to power our cities and transport. To what extent do you agree or disagree with this opinion?

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.
