Unveiling the Environmental Impact of Virtual Events: Debunking the Green Credentials
Introduction:
The pandemic accelerated the popularity of virtual events, but as we transition back to physical gatherings, virtual event providers are touting their green advantages over in-person events. However, to truly assess their environmental impact, we must delve into the fundamentals of virtual events. By examining the raw data and crunching the numbers, we can ascertain the veracity of their green credentials.
Virtual Events and Energy Consumption:
Cloud-based technology, the backbone of virtual events, currently consumes as much energy as the aviation sector, accounting for 2% of global energy usage. While virtual events do save on travel emissions, it is crucial to analyze energy consumption at the fundamental level to determine if the marketing message is indeed misleading.
Unveiling Energy Consumption in Virtual Meetings:
Let's consider a one-hour virtual meeting between two participants residing in the same city, with video and audio enabled. Such a meeting consumes approximately 1 kWh of energy, equivalent to driving a petrol car for 2 km or traveling by train for 10 km. If the meeting expands to three participants in the same city, the energy consumption triples to 3 kWh, analogous to driving a car for 6 km or taking a train for 30 km. Doubling the meeting duration to two hours doubles the energy consumption to 6 kWh, akin to driving a car for 12 km or taking a train for 60 km. Introducing one participant from another city within the same country quadruples the energy usage, and adding another person from a different country increases it tenfold. Consequently, a two-hour meeting involving five people results in an energy footprint of 240 kWh, comparable to driving 480 km or traveling 2400 km by train.
Scaling Up to Virtual Events:
Virtual events often involve thousands of participants connecting globally and spanning multiple days. Applying the aforementioned calculations to an average virtual event with 1000 attendees over 2 days, each lasting 6 hours, and considering the same distribution of attendees as before, the energy consumed amounts to 1.5 gigawatt-hours. This is equivalent to the output of 4.5 million solar panels operating at full capacity in full sunlight.
Exploring the Impact of Video Streaming:
Research conducted using the popular YouTube video "Luis Fonsi - Despacito ft. Daddy Yankee," which has been viewed 6.9 billion times worldwide, revealed that it consumed a staggering 900 gigawatt-hours of energy. To put this into perspective, this energy consumption equates to the annual energy use of five African countries. Video streaming alone accounts for 60% of all cloud-based technology energy usage.
Streaming Content and Virtual Events:
Virtual events revolve around streaming content to attendees and facilitating live streaming among participants. Considering an average virtual event with 1000 attendees, featuring 6 hours of live content per day and 2 hours of networking, the event would generate 16 million views of a 4-minute video on YouTube. Just 400 such events would equate to the energy consumption of the "Luis Fonsi - Despacito ft. Daddy Yankee" video.
Presentations, Images, and Energy Consumption:
Research focused on Cristiano Ronaldo's Instagram account, boasting 240 million followers, revealed that each uploaded photo consumes 36 megawatt-hours of energy. This is comparable to adding 10 new 3-bedroom houses to the UK's national electricity grid. Photos account for 5% of cloud-based energy usage. In the context of a virtual event with 1000 attendees over 2 days, assuming each attendee posts one image daily and has an average following of 500 people, it would generate 1 million views. Only 240 virtual events of this scale would match the energy consumption of the Cristiano Ronaldo example.
Unveiling Cloud Ownership and Environmental Impact:
The cloud-based technology sector is dominated by several leading companies, with Amazon Web Services (AWS) commanding a 32% share, followed by Azure, Google Cloud, Alibaba Cloud, IBM Cloud, Salesforce, Tencent Cloud, and Oracle. The choice of service provider is crucial because it influences the green credentials of virtual events. The top 8 providers have publicly expressed their commitment to minimizing environmental impact, with AWS aiming to be carbon neutral by 2025. However, the company's rapid growth rate suggests it will surpass the aviation sector's energy consumption by 2024. AWS accounts for over 66% of all Amazon-related business energy use, including transportation and packaging.
The Need for Regulation and Sustainable Practices:
While virtual events have yet to claim green credentials, certain actions can be taken to make them more environmentally friendly. These include turning off video streaming to reduce energy consumption, connecting to the event via Wi-Fi rather than 3G, 4G, or 5G, opting for alternative travel options when feasible, using lower-resolution content to conserve energy, and raising awareness about sustainable virtual events. Additionally, the cloud-based technology sector should be regulated akin to the aviation industry, ensuring transparency regarding environmental impact information.
Conclusion:
To accurately evaluate the green credentials of virtual events, we must delve into the underlying energy consumption and environmental impact. While the industry moves toward immersive virtual reality and Metaverse events, the current trajectory appears to undermine any claims of sustainability. However, by adopting sustainable practices and demanding transparency from cloud-based technology providers, we can pave the way for greener virtual events.
