Scramjets of hypersonic vehicles feature huge heat flux inside which can be harvested by thermoelectric devices as auxiliary power source. As a preliminary study to support scramjet-based thermoelectric generation, some work focusing on enhancing output power of thermoelectric generators (TEGs) was undertaken. Firstly, brief rules to increase TEG output power were summarized by analyzing a one-dimensional...
While most of previous studies on China's energy conservation took the huge country as a whole, this manuscript revealed the obvious regional disparities in energy consumption of China's 30 provinces. Based on a hybrid energy input–output model, the total energy consumption of different regions was decomposed and compared using three measurements of embodied energy in inter-regional trade: 1) only...
In this paper, we propose a simplified method and build a model accordingly for estimating the energy-saving potentials of building construction and demolition with the consideration of China's rapid growth of building construction and its short actual lifespan of buildings. To demonstrate the practicability of the proposed method and model, we further develop an illustrative case study to estimate...
Historically, many resource conservation campaigns failed because they paid inadequate attention to the interests of stakeholders. As a consequence, stakeholder analysis has gained increasing attention in order to avoid potential policy failures in the related fields. However, the stakeholder analysis of China’s energy conservation campaign still has been under-developed. This paper proposes a network-based...
We propose in this paper an integrated energy strategy based on a systems approach to address the energy challenges and energy dilemma in China. First, we give a review of existing approaches to energy planning and strategic management, followed by a discussion on the major relationships among energy, economical, environmental and societal systems. Next, we present a conceptual system model with alternative...
