Climate Contradictions
Last week, Microsoft announced that it would spend approximately $80 billion during this fiscal year to build data centers for its booming artificial intelligence business. That gargantuan sum is a testament to the opportunity that Microsoft and other tech giants see in A.I.
The Opportunity and the Challenge
It also has the makings of a climate conundrum. In order to power all of those data centers, Microsoft and other tech companies building similar projects are going to need huge amounts of electricity. That means ever greater strains on a power grid that is still, to a significant extent, fueled by natural gas, and to a lesser extent, coal.
The Climate Impact
In the next three years alone, data centers are expected to as much as triple their energy use, according to a new report supported by the U.S. Department of Energy. Under that forecast, data centers could account for as much as 12 percent of the nation’s electricity consumption by 2028. McKinsey & Company, the international consulting firm, expects global demand for data centers to grow at roughly 20 percent a year through the end of the decade.
Climate Contradictions
There’s rich irony in the fact that it is Microsoft and other tech companies that are responsible for a surge in energy demand, and thus an uptick in planet-warming emissions. For the past decade, these same companies have been leading corporate America’s efforts to combat global warming. There was Microsoft’s promise in 2020 to remove all of its historic emissions from the atmosphere. And Amazon’s climate pledge. And Google’s net-zero goals. Now those same companies are watching their climate targets recede thanks to their big bets on A.I.
The Promise of A.I.
A.I. evangelists at these companies say their technology is poised to improve energy efficiency around the world and deliver breakthroughs in the production of clean power. If this comes to pass, today’s spike in emissions will be just a short-term disruption to their climate goals.
Renewable Energy and Nuclear Power
Microsoft and Google have both reported sharp jumps in their emissions in recent years because of the soaring energy needs of data centers. While that may seem like the makings of a giant contradiction, it could turn out to be a good thing, in the long term, for the future of clean power. A.I. could also lead to a renaissance in nuclear power, as companies like Microsoft and Google invest in small, modular reactors that are designed to be more efficient and safer than traditional nuclear plants.
Natural Gas and Carbon Capture
The scramble to meet the energy demands of data centers is leading to a flurry of investments in natural gas. Gas is the largest source of power for the U.S. grid, accounting for about 42 percent of electricity generation. And given the number of gas-fired power plants already out there, it’s also the fuel source that is easiest to scale up quickly to meet the additional demand coming from data centers. But burning natural gas releases potent planet-warming emissions. While it emits less carbon dioxide than coal and oil, burning gas releases lots of methane, which traps heat in the atmosphere. A new generation of technology, carbon capture and storage (CCS), has the potential to make natural gas less polluting. But carbon capture technology is expensive, and its widespread deployment is a long way off.
Conclusion
In the long term, could artificial intelligence help solve climate change? That’s the hope, and it’s a vision shared not just by the executives who stand to profit from the A.I. boom. Whether it’s making traffic patterns and airline routes more efficient, optimizing the way electricity flows through the power grid or identifying new technological breakthroughs, A.I. proponents say that the technology has the potential to help save more power than it consumes.
Frequently Asked Questions
Q: What is the impact of A.I. on the climate?
A: A.I. is expected to have a significant impact on the climate, with data centers set to triple their energy use in the next three years, leading to increased planet-warming emissions.
Q: What are the challenges of meeting the energy demands of data centers?
A: The challenges include the need for huge amounts of electricity, which puts a strain on the power grid, which is still largely fueled by natural gas and coal.
Q: Can A.I. help solve climate change?
A: Yes, A.I. proponents say that the technology has the potential to help save more power than it consumes, making it a key player in the fight against climate change.
Q: What are the alternatives to natural gas for meeting energy demands?
