In a recent article, Jiang and Lin (2012) applied an econometrical equation to project China's energy demand with scenarios and made comparisons in industrialization and urbanization period across countries to drive some "stylized facts" regarding energy development dynamics. We argue that the equation form and variable selection should be altered, and did tests with the changed equation form to better reflect the theory and economic meaning. Using regression equation based on the past trend to project the future cannot capture the important policy and technology factors and thus problematic generally, especially for the country in transition like China.
