Maximizing server efficiency is becoming more difficult

Many organizations still do not tap into the potential power efficiency gains hidden in servers. Without operational focus on extracting those, future server platforms may bring marginal, if any, energy performance improvements.

Should data centers sell their heat?

Historically, data center waste heat recovery has been promoted with a focus on the benefits for the heat off-taker. And yet, the overall winner in most situations is the data center operator — even if they are not paid for heat.

On-site natural gas: why some sites need it

Some operators are using natural gas for on-site power where the local grid is constrained. This will increase their emissions — but gas is essential in the transition to renewable energy and operators’ use of it is best seen in this light.
