Power Usage• The more electrical devices we use the more power is required.• The more power required the more fossil fuels burnt at power stations (coal). This produces more Carbon Monoxide which filters into and destroys our Ozone Layer. The changes to the Ozone Layer are contributing to Climate Change.• Employees need to ensure that our electrical devices are switched off at the wall after use and only used when required.
Reducing Energy Consumption• Organisations and individuals need to use power saving strategies to reduce this effect such as; Shutting down computers at night Using screen savers and sleep modes on the computers Buying energy efficient technology
E-Waste• E-waste is defined as all obsolete or outdated computers, televisions, cell phones, printers, PDAs, and thousands of other devices commonly used in offices, homes, and by people on the go.• The global technological revolution is fueling the rapidly increasing e-waste recycling problem.• The demand to effectively and safely recycle the obsolete electronics is pushed by the same demands our society imposes to manufacture the new, smaller, faster more efficient technology.
Disposal of Technology• At present rate most technology reaches its used-by date within 4 years of purchase.• Millions of tonnes of empty laser printer cartridges and computers are dumped into landfill.• Some of the toxins to the environment in computers include lead, mercury and plastics.
What can be done?Three strategies we can take to reduce thispollution;1. Recycle and/or Reuse2. Responsible disposal3. Purchase recyclable technology
ReuseThere are a number of ways organisationscan do this;1 Upgrade their computer with newer components (ie RAM, CPU etc)2 Strip their old computers and use them for parts.
Responsible Disposal1. Pass on their old machines to computer resellers like South West Recycling or Government recycling agencies.2. Donate old technology to schools, and other charities.3. Sell their technology to staff members or the general public.
Purchasing Environmentally Friendly Products• Organisations can start buying products which are made from components which are more environmentally friendlier when they are no longer required.• Buying of recycled ink toner cartridgesie Apples new MacBook Pro. Aluminium casing that can be recycled, glass screen that can be recycled and no mercury in the screen. LINK
So Exam Question??You need to remember that whenever we aretalking about the impact of IT we remember todiscuss these issues.Increase in power usage of more IT leading to theburning of more fossil fuels (coal) to create power.Damaging Ozone LayerThe disposal of the IT, contribution to landfill andpossible toxic chemicals inside IT.Reductions in paper usage
