20世纪中期以来消费主义的盛行试图表明物质消费与生活幸福成正比,然而消费的增长果真会带来幸福吗?保罗·萨缪尔森的幸福方程式告诉我们,幸福不仅仅取决于消费的丰俭,还取决于欲望的多寡。那么,我们到底需要消费多少才可以满足需求呢?为维持这一消费水平,又需要消耗多少能源和产生多少碳排放呢?本文从理论层面论证了我国重塑能源生产和消费体系的必要性,指出传统能源的生产和消费方式是引起生态环境恶化的重要源头,推进生态文明建设必须重塑能源。重塑能源,提高效率和控制能源消费总量是关键,发展清洁低碳能源是根本,转变发展方式是前提,引导消费模式是基础。 The prevalence of consumerism since the mid-20th century has attempted to show that material consumption is directly proportional to the well-being of life, but does the increase in consumption really bring happiness? Paul Samuelson’s equation of happiness tells us that happiness depends not only on the abundance of consumption , But also depends on the amount of desire. So how much energy consumption can we meet the demand? How much energy should be consumed and how much carbon emissions should be consumed in order to maintain this level of consumption? This paper demonstrates the necessity of reshaping the energy production and consumption system in China from a theoretical perspective, It is pointed out that the traditional way of energy production and consumption is an important source of the deterioration of the ecological environment. To promote the construction of ecological civilization, we must reshape the energy. Reshaping energy, improving efficiency and controlling total energy consumption are the keys. Developing a clean and low-carbon energy source is essential. Changing the mode of development is the prerequisite and guiding consumption patterns is the foundation.
