Shift Towards Renewable Energy-Powered Data Centers

A notable trend shaping Japan's data center market is the transition towards renewable energy-powered facilities. With Japan committing to carbon neutrality by 2050, data centers are embracing green energy solutions. In 2023, more than 100 MW of data center capacity will be powered by renewable sources such as solar and wind energy. Operators are funding on-site renewable energy generation, with solar panel installations covering more than 500,000 square meters of data center rooftops. The use of advanced cooling technologies, like liquid immersion cooling, has been enforced in facilities accounting for 150 MW of capacity, lowering energy consumption significantly in the data center market.

Furthermore, waste heat recovery systems are in place in 20% of new data centers, contributing to energy efficiency. The reduction in carbon footprint aligns with corporate sustainability objectives, making renewable energy-powered data centers more attractive to businesses conscious of environmental impact. Government incentives play a role as well, with subsidies totaling more than US$ 1 billion granted to companies investing in green data center technologies. Collaborations between energy providers and data center operators have led to power purchase agreements for renewable energy supply amounting to 500 GWh annually. This trend not only supports environmental objectives but also positions Japan as a leader in sustainable data center functions.
