A 2016 study from the Department of Energy’s Lawrence Berkeley National Laboratory gives us an idea of the sort of things to consider in this arena. The outlook gives reasons to both be alarmed and also be hopeful.

The foremost takeaway is that while data centers are growing in number, their energy consumption is starting to plateau out of necessity, as the dramatic increase in cloud computing has actually forced tech companies to become more efficient. The biggest companies, according to the Berkeley Lab report, are actually remarkably efficient.

Data center efficiency is measured by power usage effectiveness (PUE) rating. PUE is found by measuring a facility’s total power delivered divided by the power used by its IT equipment. Under this rating, the platonic ideal is a PUE of 1.0: power input and output perfectly balanced. Google, then, is in pretty good shape as far as this standard goes, with the average PUE of all its data centers currently at 1.11.

Efficiency, however, can remain good as power consumption increases, and consumption is going to remain a problem.

Data center energy consumption has been a concern for some time now, particularly in the United States, where data center energy consumption dwarfs that of the rest of the world at 1.8 percent of all energy used in the countrySmaller data centers, which estimates say make up 60 percent of data center energy-use, are inefficient compared to the biggest players, and with no legal standard or universal benchmark, there’s no way to ensure that efficiency gap is closed.

Making this problem even more dire is our current political climate, where developing sources of clean, renewable energy is an idea met with hostility by countries like the United States throwing their weight behind fossil fuels, even outside of its own borders. That doesn’t even account for the ways games contribute to the world’s electronic waste problem. E-waste is toxic, and only 40 percent of it is properly recycled.

And all that is before you even start to think about climate change, and the urgent action needed to avert a major crisis in our lifetime.

Video games cannot do this forever. If any of these things were to collapse—the people who make them, the economy they’re sold in, the ecosystem we’re all a part of—it would be catastrophic. All of them at once? That’s a disaster we need to talk about, openly. Because there are solutions to these problems.

Some of them are small, like making sure you know how to properly dispose of e-waste, should you need to throw out a busted console or peripheral, and doing what you can to live sustainably, even though climate change certainly requires the sort of large-scale action that only governments can enact. To that end, you can take more involved action, like calling your local congressperson or government representative and asking if climate change and environmental concerns are on their agenda, and keeping apprised of any legislation up for voting in local elections.

Other solutions are harder to parse. How do we account for the data center sprawl of tech companies and their energy consumption? Is it ethically sound to use a service like Project xCloud or Google Stadia or Playstation Now, knowing all this? Should we push for a global green tech agreement of some kind, so companies that contribute to server sprawl and energy consumption do so in a sustainable way? A carbon tax seems like a good start, but this is a problem in need of many answers, not one.

Some solutions are, thankfully, underway. Labor practices have come under scrutiny and developers are beginning to discuss organizing in earnest. Unionization is not going to solve every problem, but it can lead to meaningful progress in a lot of ways that trickle outward into other arenas. More equitable practices can mean the relentless pace of development is slowed down, which could make for fewer, better games and a course correction in supply and demand. Or it might only make things marginally better.

Sony, Microsoft, and Nintendo all have stated sustainability initiatives and reports, but these programs are buried in corporate sites and paperwork—a better approach would be to make sustainability as big a talking point as load times or ray-tracing. Something we could look at and compare to the previous year, and make note of how better off we are.

These are big, insurmountable-seeming problems, but like all incredibly big projects—like, say, game development—they’re things that can be done, slowly, a little bit at a time. We just have to start.

It’s unlikely that video games will ever truly go extinct. We’ll probably always have something called “video games,” but what those games will look like is still very much in flux. There’s no guarantee that the way games are currently made will remain viable for another 10 years—games aren’t even made today the same way they were 10 years ago. They will look different. They will change because they can, and because they must. Hopefully, all the ways games change will be on our terms—otherwise disaster will change them for us.
