Hardware & Software Developments Environment
Environment • video conferencing • reduces the need to travel = less CO2 emissions • wireless technologies • less need for cables which can be unsightly (& safety risk?) • mobile systems require less power than desktop systems • unsightly cables & masts that can be seen and ruin landscapes. • mobile phone networks have potential health risks (?) • sensors used to monitor the environment • Modelling software can forecast what is going to happen • polar ice, ocean currents, desertification, deforestation, ozone layer ….. • help to prevent serious damage, injury, loss of life ….. • weather could be predicted • computer modelling based on rules • gases emitted into atmosphere to change the pattern of undesirable weather? • farmers can use sensors that detect rainfall • less water required (automated sprinklers when needed)
Environment • Energy usage • increased use of ICT systems has higher energy costs • electricity needs to be generated • Electronic Waste • new technologies = throw away older hardware • landfill dumping (> 1 million tonnes per year) • poisonous components of hardware (lead, arsenic, cadmium …) leach into water • Raw materials & sustainability • new hardware requires manufacturing • limited supply of raw materials • need to recycle components • Building management • IT systems generate heat & require cooling • energy requirements for air conditioning • computer-controlled environment systems reduce energy use
Environment • Health & Safety • working environment? • long-term effect of use of ICT at work & for leisure • back-ache, eye-strain, RSI ….
