Q & A

What is the energy footprint of a data center?

The energy footprint of a data center is determined by the computer equipment and cooling systems within it. Despite the high energy consumption, advancements in energy efficiency and better servers have kept energy consumption flat even as more data centers are built.

How much energy do data centers consume according to the 2014 study mentioned?

According to a 2014 study, data centers consumed over 70 billion kilowatt hours of energy, which is comparable to the annual energy consumption of a small town or city.

What are the energy and carbon benefits of using the Cloud instead of a private data center?

Companies that switch from having their own data center to using the Cloud can enjoy about a 93 percent improvement in energy efficiency and about a 98 percent improvement in carbon efficiency.

What is Microsoft's stance on carbon neutrality and how do they achieve it?

Microsoft has been carbon neutral since 2012. They achieve this through an internal carbon tax that influences decision-making to reduce carbon consumption and by investing in efficiency programs and renewable energy.

What is Microsoft's goal regarding renewable energy for its data centers?

Microsoft has committed to using at least 70 percent renewable energy for its data centers by 2023, with a long-term goal of reaching 100 percent renewable energy use.

What innovative energy technology is Microsoft investing in?

Microsoft is heavily investing in energy storage systems, particularly researching and testing new systems that could allow data centers to act as assets to the energy grid, especially in terms of handling the intermittency of renewable energy sources.

How does energy storage play a role in the future of data centers according to Sean James?

Energy storage is crucial for the future of data centers as it can help manage the intermittency of renewable energy sources. Data centers could act as shock absorbers for the grid, storing energy when it's abundant and releasing it when it's scarce.

What is the significance of fuel cells in the energy transformation of data centers?

Fuel cells are significant because they convert chemical energy directly to electrical energy without combustion or emissions. They offer high efficiency and the potential to integrate closely with servers, reducing energy loss during transmission.

What is the potential role of artificial intelligence in managing energy networks sustainably?

Artificial intelligence can play a crucial role in managing the complexity of future energy networks, especially with the increased variability of renewable energy sources. AI can help automate decision-making and balance energy supply and demand efficiently.

What does Sean James suggest is needed for a grid powered by 100 percent renewable energy?

Sean James suggests that an 'energy storage miracle' is needed for a grid powered by 100 percent renewable energy. This would require energy storage systems capable of storing energy for extended periods, potentially across seasons, to balance supply and demand.

How does hydrogen energy storage relate to the future of renewable energy use in data centers?

Hydrogen energy storage is promising for data centers because it allows for the conversion of excess renewable energy into hydrogen through electrolysis, which can then be stored and used to generate electricity when needed, thus complementing the intermittency of wind and solar power.
