Green streaming involves sustainable and eco-friendly practices, such as optimizing CDNs, using edge servers, minimizing data transmission, prioritizing low-resolution and offline videos, and employing adaptive bitrate streaming. These practices reduce the carbon footprint of streaming videos while ensuring their quality.
According to the IEA, data centers and data transmission networks that support video streaming contribute 1% of the global energy-related greenhouse gas emissions. That’s why green streaming is a must to alleviate its impact on the environment. Below are 11 ways to adopt it!
In this article:
Utilize Adaptive Bitrate Streaming
Adaptive bitrate streaming, as its name implies, automatically adapts the video resolution based on users’ data connection. Each video has multiple versions available at different resolutions. When viewers’ Internet connection is weak, or their devices don’t support HD resolution, it will automatically change to lower-definition quality.
Unlike traditional streaming, which prioritizes crisp, sharp videos, ABR helps conserve data and energy. Giants like Netflix and Hulu also leveraged this technique to embrace green streaming.
Optimize Content Delivery Network
The longer data travels from data centers to your device, the more energy it uses to stream a single video. Therefore, content delivery network providers utilize edge servers to position their servers closer to the audience, thereby reducing the distance and lowering energy usage. They also evenly distribute data among servers to avoid overloading them and optimize resource usage.
Content routing is also optimized by using algorithms to adjust data routes in real time based on server loads and network conditions. Additionally, many CDN providers, such as Cloudflare, Fastly, and Akamai, have transitioned to renewable energy sources, including solar and wind power.
Improve Processing Capabilities
Another way to pursue green streaming is to employ encoding methods that require less energy, including batch processing, especially during off-peak hours. Besides, specialized hardware, like ARM architectures and GPUs, can perform encoding tasks more efficiently than normal CPUs.
By using VMs and containers, a single physical server can host many different applications or services simultaneously. This means the server is working harder and more consistently rather than sitting idle.
Optimize Storage
The easiest way to optimize data storage is to compress videos. Much like when you use a video resizer to downsize a video, CDN providers like YouTube utilize advanced codecs, including H.265 and AV1, to compress videos into a smaller size without affecting their quality. This can save up to 50% of energy in some cases.
Duplicate content should also be eliminated to free up data storage space. Additionally, data not in frequent use can go into cold storage to save power and space.
Switch To Low-Resolution Streaming
We all love high-definition videos with sharp images, but this isn’t necessary if we’re watching on our mobile devices. Unlike on TVs or computers, lower-resolution videos appear clearer on a smaller screen. On some streaming platforms, the video resolution on mobile devices is set to 720p by default rather than 1080p or 4K.
According to Statista, about 70% of US viewers watch videos from their smartphones (as of March 2023), so this is a great way to cut down on energy without impairing the viewing experience.
Analyze And Minimize Data Transmission
It’s essential to analyze the audience’s behavior, such as their favorite content, bitrates, watch time, etc., to minimize the data used. For example, CDN providers can identify popular videos and cache or preload them closer to the viewers, reducing the need for repeated data transfer.
During off-peak times, they can minimize unnecessary data transmission to save energy. Additionally, these user insights also empower providers to fine-tune their ABR algorithms, thereby reducing bandwidth costs and energy consumption.
Encourage Offline Viewing
According to the IEA, it requires a whopping 1600W of electricity to watch a single YouTube video. However, by switching to offline viewing, we can significantly reduce that amount of energy. Even better, this practice eases the data traffic on servers during peak hours.
Many platforms, such as Disney+ and Netflix, allow users to download their content for later viewing. This is a game-changer for those who are often on the go or living in remote areas with little to no Internet access.
Streamline Data Center Operations
The way data centers operate significantly contributes to green streaming adoption. To make them more eco-friendly and sustainable, consider leveraging innovative cooling technologies that use less energy and shifting to renewable energy sources.
Take Google, for example. The company claimed to use 64% carbon-free energy among its data centers worldwide from 2022 to 2023. Its AI-powered cooling mechanism also cut down on annual carbon dioxide emissions.
Make Use Of AI
Artificial intelligence can benefit both video streaming providers and video creators alike in green streaming. For CDN providers, AI models can automatically detect types of scenes, predict optimal encoding settings, and find the best codec for each video. This streamlines the encoding process and minimizes unnecessary data used for repeated tasks.
Content creators can also embrace green streaming by using AI. For example, an AI video generator enables them to export videos in various resolutions and bitrates, facilitating adaptive bitrate streaming.
In addition, AI can analyze video content to intelligently apply compression, focusing on areas with less detail or motion to achieve higher compression ratios. Not to mention, using AI video generators eliminates the need for a physical studio, reducing on-site electricity usage.
Employ Renewable Energy
Data centers consume energy every step of the way, from processing content on servers, cooling IT equipment, and powering infrastructure to lighting and other purposes. These tasks require a significant amount of power while also leaving a substantial carbon footprint.
By switching to renewable sources like wind, solar, and tidal energy, we can alleviate the burden on our planet. Some pioneers in embracing green energy include Google, Microsoft, and Amazon.
Raise Viewers’ Awareness About Green Streaming
Green streaming is a long-run journey that requires efforts from both CDN providers and viewers alike. Providers can provide users insights into their energy usage to encourage more sustainable streaming habits. It can be as simple as watching lower-definition content, downloading videos for offline viewing, or disabling autoplay.
