Green Computing.pptx

Climate change is being driven by human activities like burning fossil fuels which release greenhouse gases and warm the planet. Effects are already occurring like sea level rise, stronger hurricanes, more droughts and will continue/worsen if emissions aren't reduced. Green computing aims to limit environmental impact of technology through reducing energy/emissions in manufacturing, data centers and use, but faces challenges due to lack of concern, rapid innovation and upfront costs. While it makes progress, more can still be done and some companies use it for appearances while causing other environmental damage.

Climate Change Climate change refers to long-term shifts in temperatures and weather patterns. These shifts may be natural, such as through variations in the solar cycle. But since the 1800s, human activities have been the main driver of climate change. Burning fossil fuels generates greenhouse gas emissions that act like a blanket wrapped around the Earth, trapping the sun’s heat and raising temperatures.
Damage Done The effects of human-caused global warming are happening now, are irreversible for people alive today, and will worsen as long as humans add greenhouse gases to the atmosphere. Sea Level Will Rise 1-8 feet by 2100 Climate Changes Will Continue Through This Century and Beyond Hurricanes Will Become Stronger and More Intense More Droughts and Heat Waves Longer Wildfire Season Arctic Is Very Likely to Become Ice-Free
Green Computing • Green computing (also known as green IT or sustainable IT) is the design, manufacture, use and disposal of computers, chips, other technology components and peripherals in a way that limits the harmful impact on the environment, including reducing carbon emissions and the energy consumed by manufacturers, data centers and end-users. Green computing also encompasses choosing sustainably sourced raw materials, reducing electronic waste and promoting sustainability through the use of renewable resources. • The potential for green computing to have a positive impact on the environment is considerable. The information and communication technology (ICT) sector is responsible for between 1.8% and 3.9% of global greenhouse gas emissions. Moreover, data centers account for 3% of annual total energy consumption — an increase of 100% in the last decade. This Photo by Unknown author is licensed under CC BY.
The evolution of green computing In 1992, the Environmental Protection Agency (EPA) began the Energy Star Program in the United States, which aimed to promote and recognize energy efficiency. The program brought about numerous other initiatives to increase efforts toward green computing. Energy Star-certified products must meet certain operation standards and have power management features that non- certified products may lack. This Photo by Unknown author is licensed under CC BY-ND.
Green Computing Leaders • Dell Dell has been one of the leading innovators in the tech sector when it comes to packaging and recycling and in 2014 the company launched its ‘2020 Legacy of Good’ plan. • IBM IBM has been one of the ‘green’ leaders in tech for a number of years, dating back to 1967 when it issued its first policy on environmental affairs. • Cisco Cisco has been working hard to meet targets on Greenhouse gasses, which it met in 2012 and is now working work to reduce them further. • Adobe Adobe has long had a green outlook, whether it’s focusing on energy conservation, green buildings or waste reduction. • Apple Apple is very keen on having a good image, whether it comes to its products or how they operate. The company states to be the only company which runs its data centers through 100% renewable energy and also has a product range which exceeds the ENERGY STAR guidelines.

Challenges to implementing green computing One of the greatest barriers to advancing green computing is a lack of concern. Few people think of the IT industry when they think about climate change. Along with a general lack of concern, the IT market has developed in a way that prioritizes the development of smaller and faster components and devices rather than environmentally friendly ones. The fact that technology evolves and changes very rapidly presents challenges in extending the lifecycle of products and requires technology makers to ensure each iteration continues to meet eco-friendly standards. Switching from a conventional set up in a factory, data center or corporate office to a green configuration requires an often- substantial up-front capital investment that represents an additional potential barrier.
Still a long way to go... • One of the main winners to come out of the green computing idea is the lithium battery that challenges to replace fossil fuels as the primary energy resource. Countries, tech companies and vehicle manufactures around the globe are competing against each other to mine lithium which ironically itself is a damaging process to the environment. • The extraction process of lithium is very resource demanding and specifically uses a lot of water in the extraction process. It is estimated that 500,000 gallons of water is used to mine one metric ton of lithium. • Lithium-ion batteries contain metals such as cobalt, nickel, and manganese, which are toxic and can contaminate water supplies and ecosystems if they leach out of landfills.

Saving Face • Although green computing is a very positive step forward towards reducing the global carbon footprint, many big corporations are using green computing as a cover to hide human rights violations in workplaces and environmental damage. One leading example of it is Volkswagen when in 2015 it was revealed that engineers at the German auto maker had rigged 11 million of its supposedly clean diesel engines with software that tricked emissions tests, allowing the cars to spew far more pollutants than legally allowed. • Other examples are Coca-Cola who was the sponsor at the Cop27 Climate summit when in fact it is one of the biggest plastic waste contributor in the world.
Do more! Green computing has the power to lessen the impact of computing on the environment. However, the ICT industry has an opportunity to do much more by using technology to benefit the environment through programs and systems designed to reduce power consumption, improve water management and embrace virtualization as a way to conserve energy. Wherever you are on the path to green IT and sustainability, one practical first step that can make a noticeable and immediate impact on energy consumption is to ensure your applications only consume the resources they need, and nothing more. This materially reduces waste (cost and carbon footprint) in data centers and the public cloud.
There's only one Earth, embrace it.
