green software – 2 Different Best Perspectives

What is green software?

Green software, or sustainable software, is like eco-friendly computer programs. It means making software in a way that uses less energy and doesn’t harm the environment much. When we talk about green software engineering, we’re thinking about how to design and build software in a smart way, considering things like how computers are made, where they are kept (data centers), and even how electricity is used.

The goal of green software engineering is to create programs that don’t release a lot of harmful gases into the air (like greenhouse gases) and don’t make a big mark on the environment. It’s like trying to make computer stuff in a way that’s kinder to our planet. This is important because it helps companies reduce the amount of pollution they cause and be more responsible for the Earth.

Principles of green software

The principles of green software are a set of concepts that software engineers should follow when they’re designing, building and deploying sustainable software applications.

There are eight principles of green software development:

1. 1.Carbon Emissions: When developers create software, they should try to make it useful for users while also making sure it doesn’t create a lot of pollution (carbon emissions).
2. 2.Energy Efficiency: Good software uses parts that don’t need a lot of electricity. Think of it like using light bulbs that give off a lot of light but don’t use much power.
3. 3.Carbon Intensity: This is about where we get our electricity. It’s better if companies get their electricity from sources like the sun or wind because they make less pollution.
4. 4.Embodied Carbon: When companies make and throw away electronic devices (like computers or phones), it creates pollution. We should try to make software that doesn’t add to this pollution.
5. 5.Energy Proportionality: The more we use a device, the better it should be at using electricity. It’s like making sure a toy car goes really fast when you play with it a lot.
6. 6.Networking: When computers talk to each other, it uses electricity and makes pollution. We should try to make software that sends less data and doesn’t make computers work too hard.
7. 7.Demand Shaping: Sometimes, we can use computers more when there’s a lot of clean energy available. It’s like deciding to play more video games when the sun is shining and the wind is blowing.
8. 8.Measurement and Optimization: We should always try to make software better over time. It’s like making a game more fun by fixing the rules and making it easier to play. This also helps make sure it doesn’t create too much pollution.

Benefits of green software

There are business benefits, as well as environmental benefits, to green software, including the following:

1. Less Complicated Architecture: Green software is like making a simple puzzle instead of a really tricky one. When software is less complicated, it uses less energy, kind of like finishing an easy puzzle faster.
2. Faster Computing Speed: If you make software less complicated, it works faster, like a race car that doesn’t have too many twists and turns.
3. Cost Savings: Green software is like turning off lights when you’re not using them. It uses less energy, so it costs less money. Imagine having to pay less for your toys because they don’t need as many batteries.
4. Brand Loyalty: Imagine you like a certain brand of toys because they care about the environment. Companies that make green software are like those cool brands. People like them more, and even investors (the grown-ups who help companies) notice and want to support them. It’s like picking the best team for a game because they play fair and care about everyone.

Examples of green software

1. Companies and Climate Crisis: Some big companies, like Microsoft, Thoughtworks, Accenture, and GitHub, want to help with the climate crisis. They’re not just saying they won’t add to the problem; they want to actually make things better by using less energy and producing fewer pollutants.
2. Green Software Foundation: These companies teamed up to create a special group called the Green Software Foundation. This group wants to bring together smart people, standards (like rules), tools, and good ways of doing things to make software in a way that’s kind to the environment.
3. Microsoft’s Efforts: Microsoft, for example, not only wants to make its own software eco-friendly but is also encouraging all software makers to do the same. They believe using the cloud, changing how software is designed, and writing code in a certain way can help use less energy and reduce pollution.
4. Accenture’s Contribution: Accenture is another company doing its part. They’ve created tools and ways of working that are good for the environment. Almost all of their computer applications run on the public cloud, which is like a super-efficient computer network. They’ve also trained a lot of their workers on how to make green software.
5. Thoughtworks’ Green Cloud: Thoughtworks has something called the Green Cloud, which they believe can directly help cut down on pollution caused by using computers.
6. GitHub’s Carbon Neutral: GitHub, owned by Microsoft, has been making sure all the work done on its platform has been environmentally friendly since 2019. It’s like they’re making sure their playground (where people build software) doesn’t harm the planet.
7. VMware’s Joining In: VMware is another company that recently joined the Green Software Foundation. They’re working on using computers that use less energy and trying to design software that doesn’t need as much computing power, which is like making sure a game doesn’t need too many batteries to play.
