2. 개요 : The IPCC finds in its report on “Mitigation of Climate Change” that it is often more costeffective to invest in end-use energy efficiency improvement than in increasing energy supply to satisfy demand for energy services. Efficiency improvement has a positive effect on energy security, local and regional air pollution abatement, and employment. The report also concludes that the economic potential in the industrial sector is predominantly located in energy intensive industries. Full use of available mitigation options is not being made in either industrialized or developing nations. Many industrial facilities in developing countries are new and include the latest technology with the lowest specific emissions. However, many older, inefficient facilities remain in both industrialized and developing countries. Upgrading these facilities can deliver significant emission reductions. The slow rate of capital stock turnover, lack of financial and technical resources, and limitations in the ability of firms, particularly small and medium-sized enterprises, to access and absorb technological information are key barriers to full use of available mitigation options. It is cost effective to invest in energy efficiency These barriers can be lowered by making available the required information as well as by advancing for instance the usage of payback schemes in financing the energy efficiency investments. The IEA has made a scenario that concludes that end-use efficiency and a virtually CO2- free power sector can yield emissions stabilisation in 2050 at today’s level. End-use efficiency accounts for 36 percent of all savings in the scenario, renewables for 21 percent and CO2 capture and storage 19 percent. The remaining 24 percent is accounted for by nuclear, fossil fuel switching and efficiency in power generation.
The Motor Challenge Programme claims that motor driven systems account for approximately 65 percent of the electricity consumed by EU industry. The Motor Challenge Programme is a voluntary programme promoted by the European Commission to help companies improve the energy efficiency of their electric motor driven systems. End-use efficiency does not inflict marginal costs Switching to energy efficient motor driven systems can save Europe up to 202 billion kilowatt-hours (kWh) in electricity consumption, equivalent to a reduction of €10 billion per year in operating costs for industry.
