Google: we need more energy for AI

The US needs to accelerate power generation – from any source possible – to feed the growing demand from AI data centers, a move which could further disrupt net-zero goals.

That's according to Ruth Porat, president and chief investment officer of Google parent Alphabet, who told the CeraWeek conference that the company is concerned not enough is being done to supply energy for AI infrastructure.

"We are concerned that we are ⁠not full throttle on energy," she said at an energy conference in Houston, according to Reuters. Porat later added that the US will need every possible source of energy to meet the demands of AI and data centers required to power them.

The rise of AI has led to a boom in data centers, which has strained power supplies and grids in Europe, the US, and the UK – meeting the demand could cost hundreds of billions, noted McKinsey in a report.

Bring your own power

To help mitigate the challenge, Trump last month forced Big Tech companies to agree to generate their own power for data centers to avoid driving up energy prices any further.

"This means that the tech companies and the data centers will be able to get the electricity they need, all without driving up electricity costs for consumers," ​Trump said at the pledge signing event.

While that agreement addresses a range of issues, many big tech companies were already sourcing their own energy. Google, for example, has cut deals with modular nuclear reactor developers as well as geothermal providers.

Meta is also turning to geothermal while Microsoft and Amazon have ramped up investment in nuclear energy.

Google has also agreed to pause data centers when grids are overloaded in two US states.

Climate vs AI

However, the US government has already pushed for the use of all available sources of energy, leading to a massive uptick in the use of gas for electricity generation – suggesting the race for AI will disrupt the drive to renewable energy in the face of the climate crisis.

Indeed, research has suggested the data centre industry's emissions will triple by 2030.

Porat's call to use all sources of energy, regardless of environmental impact, runs counter to Alphabet's own efforts to decarbonize, with data centers driving a 25% increase in the use of gas for electricity production in the US in the last two years alone.

In 2024, Google admitted its own carbon emissions had leapt by 50% over the previous five years despite significant efforts to reach net zero, largely driven by data centers projects.

Google isn't the only company to turn away from green goals in favour of AI. Microsoft co-founder Bill Gates said in 2024 that the impact of data center energy demands wasn't worth worrying about.

"Let's not go overboard on this," Gates said. "Data centers are, in the most extreme case, a 6% addition [in energy demand] but probably only 2% to 2.5%. The question is, will AI accelerate a more than 6% reduction? And the answer is: certainly."

But electricity demand is climbing and AI hasn't yet supplied any answers to mitigate the impacts of the climate crisis.

AI infrastructure could use up a quarter of the UK's electricity within the next four years, effectively derailing net zero plans.

Campaigners have called for data centers to undergo stricter environmental impact assessments and be more open about their energy use.
