Amazon’s claim of achieving 100% renewable energy seven years ahead of schedule is a significant milestone, but a closer look reveals both the complexities of corporate climate action and the challenges that lie ahead.
Five years ago, in 2019, Amazon committed to powering its entire global operations with 100% renewable energy by 2030. The e-commerce giant became the largest corporate purchaser of renewable energy for four consecutive years, investing billions in more than 500 solar and wind projects worldwide, generating enough energy to power 7.6 million US homes. Fast-forward to this week and Amazon took many by surprise when it announced that it achieved its climate goal in 2023, seven years ahead of schedule.
The achievement, although noteworthy, warrants a more profound examination to understand its real impact and implications for corporate climate action. Firstly, it’s crucial to understand what Amazon means by ‘100% renewable energy’. The company is not directly powering all its operations with renewable energy but ‘matching’ its electricity consumption with renewable energy purchases.
This approach, while beneficial, does not necessarily mean that Amazon’s facilities are running on clean energy 24/7. The energy generated by those 500 projects is equivalent to the electricity consumed by the company’s data centres, corporate buildings, grocery stores and fulfilment centres in 27 countries. And since the solar and wind farms do not all directly power Amazon’s operations, most of that energy is sent to electricity grids that serve many businesses and homes.
Some critics, as per The New York Times (NYT) report, say that the company’s calculations can create a misleading impression of its effect on the climate.
Nevertheless, the scale of Amazon’s renewable energy portfolio is indeed impressive. The company has enabled projects in 27 countries, including pioneering utility-scale renewable energy initiatives in India, Greece, South Africa, Japan, and Indonesia. These efforts are expected to help avoid an estimated 27.8 million tons of carbon per year once all projects are operational.
Yet, the company acknowledges that the path forward is becoming more complex. The increasing demand for generative AI is changing energy requirements in ways that were not anticipated even a few years ago. So much so that a large data centre can consume as much energy as a small power plant serving around 100,000 homes. Therefore, tech companies are striving to meet the energy demands of AI with renewable sources.
Last month, Google announced a deal with Berkshire Hathaway’s Nevada utility to power its data centres with geothermal energy. Despite these efforts, Google’s greenhouse gas emissions increased by 13% in 2023 due to rising AI demands. This shift underscores the need for a diversified approach to carbon-free energy sources. Moreover, Amazon aims to reach net-zero carbon emissions from all of its operations, including its delivery vans, planes and other means of transportation, by 2040.
The company is considering technologies like nuclear power, battery storage, and other emerging solutions to complement renewables and balance energy needs. This flexibility in approach is crucial as the company works towards its broader goal as part of The Climate Pledge.
Promising aspects of Amazon’s renewable energy
One of Amazon’s most promising aspects of its renewable energy strategy is its focus on grid modernisation. The International Energy Agency (IEA) estimates that the world must add or replace 80 million kilometres of grids by 2040 to meet climate targets. Amazon engages with energy regulators to support grid modernisation, remove permitting obstacles, and deploy grid-enhancing technologies. This work is essential for enabling the broader transition to renewable energy.
Still, according to CDP, a nonprofit group that operates a global disclosure system for investors, companies, cities, states and regions to manage their environmental impact, Amazon received a “B” grade. Google and Microsoft received “A”grades and were commended for their commitment to clean energy and for being transparent about how they were working to achieve their climate goals.
Amazon reached its 100% clean electricity goal by building new solar and wind farms, installing solar panels on some buildings, operating on grids with high renewable energy, and utilising carbon-free energy credits. Since no company on a grid with fossil fuel plants can guarantee exclusive use of clean energy, it often buys renewable energy certificates (RECs) from solar or wind farms. By purchasing enough RECs to match or exceed its energy use, companies can claim their operations are fully powered by clean energy.
“That’s what we do, buy RECs for projects that are not yet operational,” Kara Hurst, VP of worldwide sustainability at Amazon, told NYT. Amazon’s offshore wind investments are also particularly noteworthy. The company supports nearly 1.7 GW of capacity across six offshore wind farms in Europe, making it the top corporate purchaser of offshore wind globally.
Once fully operational, these projects are expected to produce enough energy to power 1.8 million average European homes. The company’s efforts in Japan also demonstrate an understanding of local challenges and opportunities. By enabling the country’s first utility-scale aggregated solar project backed by a corporate power purchase agreement, Amazon is helping to overcome the limitations posed by Japan’s mountainous terrain.
Achieving climate goal won’t get any easier for Amazon and other
As impressive as Amazon’s accomplishment is, it’s essential to view it in the context of the company’s overall environmental impact. Transitioning to renewable energy is an important first step, but it’s only a start. Amazon’s wider carbon footprint, its vast logistics network, and the products it sells still pose a big challenge.
It’s also a question of how sustainable Amazon’s path to net-zero carbon will be in the coming years: The company, too, admitted that it “will not always be the same each year”, raising questions about the sustainability of its current achievement. As Amazon’s energy needs evolve, particularly with the growth of AI and cloud computing, maintaining 100% renewable energy matching may become increasingly challenging.
In conclusion, Amazon’s early achievement of its renewable energy goal is a significant milestone that deserves recognition. It demonstrates what is possible when a large corporation commits to climate action and invests heavily in renewable energy. However, it’s crucial to maintain a critical perspective on such announcements.
While we remain encouraged by Amazon’s advancements, we still need to keep all significant companies – not just Amazon but any other part of the global economy with substantial carbon footprints – in check on their environmental progress. The crisis of a changing climate requires nothing less than an ongoing, comprehensive response, particularly from those who possess the resources and influence to drive significant changes.
