Profit from sustainable IT
Sustainable software: high security of sovereign data decentralized using Open Source strategies
Open Source Software ermöglicht, langfristig zuverlässige und sichere Systeme zu bauen, die genau Ihren Ansprüchen entsprechen. Open Source ist kostenlos und transparent, sodass Sie unabhängig von Software-Unternehmen sind, die großes Interesse an Ihren Daten haben. Nutzen Sie diese Vorteile und werden Sie wieder Herr über Ihre Daten und Ihre IT! Ich zeige Ihnen u.a. einfache Möglichkeiten auf, die Edward Snowden für gut befindet.
Sustainable hardware: durable and energy-saving hardware with user-friendly and simple maintenance
High-quality devices are reliable from 5-8 years, cheap to maintain and purchase as second-hand products. Minimize your technological, environmental, and financial footprints by using IT equipment with low investment, maintenance and energy costs. An increasing number of manufacturers are focused on fair and resource-conserving production processes.
The result: reduced costs, improved reliability, increased security and eco-friendly IT.
With sustainable software and hardware, you can simultaneously save money and reduce your ecological footprint. In addition, you benefit from reliable and secure systems with full control over your data. Get involved with this sustainable digital-electronic movement and you'll experience benefits exceeding your new investment.
Hi! My name is Mathias Renner.
For 7 years I’ve advised clients on various aspects of IT.
After 5 years of experience with traditional IT practices, my interests lead my focus to sustainable IT solutions. IT is the backbone of the digital age we live in, and only “sustainable” IT solutions offer potential for a free and fair future for all citizens.
I am currently finishing my M.S. research in Information Systems with a specialization in energy efficiency and data analytics.
