Industrial strategy: Greens want fiber optics for the climate

[ad_1]

The parliamentary group of the Greens calls for “the extensive expansion of a comprehensive fiber optic network as the most climate-friendly and most efficient transmission technology” to be accelerated for the fixed and mobile network. The federal broadband funding program is to receive “an update” for this, and the legal entitlement to high-speed Internet planned by the federal government for 2025 will be “implemented quickly” in advance “as part of an affordable universal service”.

This emerges from a new strategy with which the opposition group wants to shape the change in industry sustainably within the framework of an “ecological-social digital transformation”. The group published it on Tuesday motion decided by her on Friday. She wants to introduce him to the Bundestag next week.

Previously had a Expert opinion from Kristof Obermann from the Technische Hochschule Mittelhessen on behalf of the Federal Association of Broadband Communication (Breko) showed last year that “real fiber optic networks with fiber to the home (FTTH) make an important contribution to more climate protection and sustainability”. The professor of electrical engineering and information technology compared the energy demand during operation and the sustainability of FTTH and copper-based telecommunications networks such as fiber to the curb (FTTC) and VDSL turbo vectoring.

In relation to the power consumption per bit rate, copper-based networks consume “three to seventeen times more power” than real fiber optics with an assumed utilization of 50 to 100 percent. With a Germany-wide supply with FTTH, up to 1100 megawatts (MW) of electrical power could be saved compared to copper-based networks. For comparison: The seventh largest German coal-fired power plant “Schwarze Pump” achieves an output of 1600 MW.

With the plan, the Greens want to give industry a strong position so that it can, above all, “meet the challenges of the climate crisis”. Germany is to become “the lead market for material and energy efficiency solutions” as well as for the circular economy. This requires a funding program for state-of-the-art recycling systems, the expansion of deposit and reusable systems and a “strengthening of repair services”. At the same time, minimum requirements for recycling systems would have to come.
