Role of BCHP in energy and environmental sustainable development and its prospects in China

Abstract

During last century, worldwide environment degradation gets more and more serious, and achieving environmental sustainable development is desirable. As many environmental issues are directly or indirectly energy related, energy sustainable development is one of the most important prerequisites for environmental sustainable development. Renewable energy technologies and energy conservation are two solutions for energy sustainable development. At present, energy-saving technology is a feasible and an effective way to achieve energy and environmental sustainable development, although renewable energy may be final solution to environmental issues. Building cooling, heating, and power (BCHP) technology, which usually use natural gas as primary energy, has high efficiency of energy utilization due to the utilization of distributed power generation and heat recovery, and thus is a promising energy conservation technology. BCHP can reduce pollutants emission and thus protects the environment besides improving IAQ and increasing reliability of building energy supply. As the largest developing country, China is just in the process of adjusting energy structure and improving energy efficiency. Because of its significant role in energy and environmental sustainable development, developing BCHP in China will help the country in optimizing energy proportion, increasing energy efficiency, and protecting environment. Therefore, BCHP technology will have broad prospects in China and it will promote the country's energy and environmental sustainable development.
