T2 - Environmental Impacts

Electricity Consumption & Its Environmental Impact

Electricity is an essential part of most peoples lives in the world now a days, which means that power plants are working harder and creating even more pollution leading to damaging the ozone layer of our atmosphere.
The ozone layer is what protects us from the heat and radiation from the Sun. Due to this being damaged, the heat and radiation cannot be absorbed and ends up passing through getting trapped in our atmosphere and raising the temperature of our planet.
Our reliance on electricity has made scientists around the world search for more environmentally friendly ways to generate electricity, e.g. Wind Turbines and Solar Panels. Although these new methods may not output as much as the old power plants, they are a big step to improving the way we create electricity whilst having little to no impact on the environment.

Improvements In Computing Power Per Kilowatt

New computer components are becoming more powerful and they are being used by even more people. To balance the amount of electricity and the increasing use of powerful computer components, these components come with technology that allows themselves to down-clock when not under heavy load. This allows the components to draw less electricity when being used for very minimal tasks, e.g. browsing the internet. For more intensive tasks, such as gaming, rendering or compiling, this technology will allow the components to speed back up to their intended speed, which will draw more power.

Increasing Amounts Of Electronic Waste

Electronic waste can be harmful to the environment if not disposed of correctly due to some components, like batteries, containing dangerous chemicals. With the increasing usage of computers in everyday life, the amount of E-waste that is produced puts a significant amount of pressure on landfill sites to stop any damage being done to the environment around them.
The heavy metal materials found in E-waste, such as lead, cadmium and mercury, can end up in the soil, the water and could potentially end up inside of people, causing very serious health issues. [1]

Need To Recycle Dangerous Chemicals, Heavy Metals & Other Components

Recycling these dangerous chemicals, heavy metals and components can lead to improving the environment and could also slow down the rate of us gathering these materials from the earth.

Issues Relating To The Export Of Waste Electronic Equipment For Recycling To The Developing World

Old computer components are recycled to developing nations, so they have opportunities to become familiar with what is used in developed nations, albeit being a few years older than what is currently used in developed nations.
One issue with this is with components becoming more powerful, they will need to draw more electricity. Developing nations already have a limited amount of electricity and these more powerful components could put a big strain on those small energy suppliers.

T1 - Hardware & Software Developments

Focus On Mobile Rather Than Desktop Computing Over the last two decades, mobile device hardware has advanced greatly. With the hardware becoming more advanced, a wide variety of software is now usable on a mobile device. The advanced hardware has allowed developers to create detailed software that was not before achievable due to the simplicity and restricted nature of mobile devices of the past. Development tools were made to make the process of creating software for mobile devices a lot easier because the more that developers want to add, the more complex the software becomes without the tools. These tools have made developing software for mobile devices quicker and easier, and with the more advanced hardware on top, a lot of developers have started creating applications that could not have been possible on mobile before. Lots of organisations have taken advantage of the advanced technologies in mobile devices by creating apps which also allows them to keep...

T1 - Emerging Technologies

Internet Of Things The internet of things (IoT) is a new technology that is on the rise and it allows anything that uses a computer to connect and communicate with other things that uses a computer. For example, a mobile phone could connect to certain systems in a home, like the new smart central heating. This can allow someone to turn the heating on before they get home, so they do not have to turn up to a cold home and wait for it to warm up. IoT could be used within an organisation to speed up workflow by connecting devices and having them communicate with each other. Unfortunately, this technology has its disadvantages, just like any other technology. Due to all the things that use a computer can now connect to the internet and communicate with each other, this makes it easier for attackers to hack into and possibly take control of more rather than being isolated to one of those systems. This can be devastating for an organisation because it would make the job of figh...
