Recent studies show that the power consumption of today's Internet is around 0.3% of the electricity supply of a typical OECD country. However, as broadband access becomes increasingly commonplace in most developed countries, the power consumption of the Internet is estimated to rise to more than 7% of a country's national electricity supply for an average access rate rising to 100 Mb/s, which translates into a power consumption of several TWh and expenses of millions of dollars and tons of carbon gas emissions per year. The power consumption of the current Internet is largely dominated by its first-mile access networks. It was shown that in a typical network scenario, transport and core networks represent roughly 30% of the total power consumption, while access networks account for the remaining 70%.

最近的研究表明，当今互联网的功耗约为典型 OECD 国家电力供应的 0.3% 左右。然而，随着宽带接入在大多数发达国家日益普及，平均接入速率达到 100 Mb/s 时，互联网的功耗预计将上升到国家电力供应的 7% 以上，这相当于每年几太瓦时的电力消耗和数百万美元的费用以及数吨碳气体排放。当前互联网的功耗主要由其第一英里接入网络主导。结果表明，在典型的网络场景中，传输网和核心网约占总功耗的30%，而接入网则占剩余的70%。
