Did you know that #datacenters use more #energy than entire countries and are responsible for about 1% of global #GHG emissions? Thus the #greening of #datacenters is critical to fight #climatechange. Taking action, we have launched jointly with the #WorldBank and #ITU and the support from Federal Ministry for Economic Cooperation and Development (BMZ) the #Green Data Center guide at the #AfricaClimateSummit ???https://lnkd.in/ge7mZasp ? Why have #data centers become so important and are growing rapidly? Demand for digital services is growing rapidly. Since 2010, the number of internet users worldwide has more than doubled, while global internet traffic has expanded 20-fold. The data centres and data transmission networks that underpin digitalisation have led to rising energy use. ? What are the negative consequences of the data center the #environment and #climatechange? Although data centers and cloud solutions are essential for storing and processing data, they are 1) highly energy intensive ?2) consume refrigerants 3) use large amounts of water for cooling 4) use large amounts of lands 4) produce a significant amount of e waste. As such, they leave a large negative environmental footprint and contribute to global #greenhouse gas emissions ?What is the digital sector doing to address this challenge? The #digital sector is the largest purchaser of renewable energy globally, with about 44% of all renewable energy produced being purchased by #tech companies. Tech companies and data center operators have improved the energy efficiency and improved the colling systems for data centers. Therefore, the energy share used by data centers has hardly changed since 2010. The negative environmental and climate impacts remain a huge challenge which require urgent action. ? What can be done to minimize or avoid these negative environmental effects? Greening data centers supports climate change mitigation and adaptation efforts, contributing to decarbonization of a country’s economy and helping meet wider sustainability goals. ? The Green Data Center guide presents a wide range of solutions to help?practitioners develop environmentally sustainable data centers, covering the following seven critical dimensions to develop #sustainable data centers: 1) sustainable design and buildings; 2) use of sustainable ICT; 3) sustainable energy; 4) sustainable cooling;? 5) climate-resilient data centers, 6) e-waste management 7) enabling enviornment for greening ICTs The guide aims to promote investment in the greening of ?data centers and increase resilience and efficiency of existing data infrastructure. ??https://lnkd.in/ge7mZasp ?
