Summary:

At our current pace of consumption, the world’s demands for compute power will quickly outpace the energy provided by our data centers. The solution is a global smart grid, and Europe provides a model for what that might look like.

For the first time, this year the number of internet-connected devices is predicted to exceed the global population. While that growth is exciting, all of these devices in their many forms come with dramatically greater demands for connectivity and bandwidth – and will generate large amounts of data that require additional storage space and compute power. Add to that the increasing adoption of cloud computing, big data analytics and other power-intensive activities, and it becomes obvious that the world’s compute power demands will quickly outpace the energy supply that today’s data centers can provide.

To get ahead of these growing demands we will need a smart grid that interconnects power plants and natural energy sources with consumers to intelligently optimize the consumption and distribution of power.

Data centers will become hubs

In order to take full advantage of innovations in smart grid technology, we must first transition data centers into the center of our power and computing activities to monitor and maximize efficiency and plan future energy and cooling sources – all while keeping an increasingly centralized society working, connecting, living and communicating.

Historically, communities were built around religious structures, such as the town church, which brought people together and became an irreplaceable pillar of the community. Today, we are experiencing a similar phenomenon wherein the data center functions as that same pillar but for an online community of enterprises and consumers, positioned at the heart of the digital economy. This will become even more pronounced in the near future, as researchers predict that nearly 75 percent of the world’s population will live in cities by the year 2050.

Efficient distribution of greener power

Many countries are already making strides to develop smart grids within a given region. The primary benefit of smart grid technology is that it allows power from, say, wind farms in Spain, to be distributed to consumers in Denmark with very little energy lost in transport and at a manageable cost. That way, areas that may not have strong natural resources to generate sustainable energy aren’t forced to rely on coal or natural gas to power their infrastructure. This will become an even more important structure as data centers proliferate to match growing global compute and power demands.

Extending the smart grid’s role

By positioning data centers as the epicenter of everything high-tech, we can extend the scope and role of the smart grid beyond efficient structures and smart power distribution. The current concept of the smart grid ensures that buildings are running as efficiently as possible as standalone structures, but also in combination with a green energy source that is distributed via a smart power infrastructure. By constantly measuring and planning future energy sources that require very little energy to generate and have little impact on the environment, data center operators could power their facilities with significantly fewer resources.

Further, by adding an autonomic planning element to the smart grid that can track energy availability and usage throughout the day, operators would be able to rely on the smart grid to determine when to switch between solar, wind or tidal energy, to name a few. This way operators can rely on the smart grid to determine the best time of day to use different types of power, streamlining the switch from one to another and contributing to a more sustainable environment by using clean energy sources.

For instance, if wind farms create the most energy in the late afternoon whereas solar panels pointed east are most useful in the morning, the smart grid can automatically switch from one power source to the other when it is the most viable and beneficial. With this level of intelligence incorporated into data centers and the smart grid linking them with one another, it’s possible that we could support continuous compute growth over many decades.

The need for a global initiative

While this may seem like a radical concept in territories like the United States or India (where the current electrical grids appear to be duct-taped together rather than planned), Europe is a great example of a region that has made significant progress to unite its energy sources and consumers. New resources are being discovered and explored regularly, offering additional juice to power the growing European smart grid, and consumers in large cities like London, Paris and Madrid are already able to benefit from energy gathered from turbines in the ocean and wind farms in the countryside.

In order to achieve true energy efficiency that goes beyond sustainable power sources, though, this must be a global initiative that is collaborated on by universities, governments, non-profits, corporations and even individuals. With global cooperation, we could see solar panels in China powering nightlights in New York City, orchestrated by a network of data centers strategically positioned around the globe.

    Transferring power is not the same thing as transferring bits. Obviously the author has no idea whatsoever how an interconnected power system is planned and operated.

    So, how exactly he is proposing to transfer power from Shangai to NYC?

    Utter nonsense. What a shame.

  2. Unless the author of this article is channeling Tesla, how are we to shift energy halfway around the world?

  3. Sorry but smart-grid will not allow you the transfer energy halfway around the world. Energy congestion management is at the heart of that problem, together with transport cost. Smart-grid is mainly focused on supply & demand management (caused by increase in sustainable energy sources) and routing energy locally in an efficient way. This is routing energy over short distances. Have a talk with a local energy transport authority; they will tell you they have the highest energy bill – all transport and conversion cost…

    Electric cars and vehicles have low emissions and can become integral parts of a smart grid, where they do not just consume power, but also provide mobile storage of energy acquired during periods of high electricity generation from renewable sources, high winds or sunshine. In times of high demand, they can feed electricity back into the grid. Therefore, electromobility’s greatest potential for climate protection is the interaction with renewable energies and sustainable mobility.

  5. Dear Leonardo, PC and Wade, I appreciate your responses (it looked like you just bought some shares in US Energy like I seem to have shares in cars :-)

    Al jokes aside; Alessandro, indeed understood a larger part of the principle; let me explain.
    In Europe we have a large Western Europe section covered by an international grid and our aim is to – over time, were not yet there – to create the super grid (from east to west and north to south including Eastern Europe).

    The idea of this is that at any appropriate place; small and/or larger energy providors will be able to connect micro generation, Sun, Hydro, Solar etc to this supergrid. While connecting micro generation systems to the supergrid you will be able to take from and feed back to the grid at any time and benefit from all sustainable power.

    Yes, inefficiency in the distribution system is a fact but think about the alternative where only micro systems with its own ineffciency and redundancy inefficiency would feed only local communities. Positively, think about the option to feed the inefficient distribution system with an over-capacity of solar, hydro or wind without the need or limited need to burn gas and coal. There is never one answer to a good solution but this is also the discussion our governments have. Have a great day. Lex

  6. Hi Leonardo, Jan and PC i value your responses and it proves that the topic is seen from a slightly different perspective depending on the area.

    Alessandra is indeed close to what I am trying to say; although PC a Tesla is indeed a nice car.

    In europe we are on our way building the supergrid. currently a large part of Western Europe is interconnected form city ring to national ring intergrated into the international ring.

    The idea – and I realize that suggesting to power the US from China creates more than an energy discussion only but please read this as a teaser and not to upset the reader – is to connect any sustainable energy source to this supergrid being able to inject and take power anywhere at any time.

    Yes, you are right when you indicate that energy losses in such transmission would be large however we are here talking about an energy source we would normally not see in a certain time zone and creates no further emisisons.

    Before I continue on this subject I look at the alternative of micro local energy sources. Let us start with a local sustainable energy source wind or solar. Wind and solar are not always available in the area and at such moment you will need to use the grid or any other – most probably – oil, gas etc. If you use the your own generation we also observe the need for inefficiency related to the redundancy required. so in a certain case you may well observe 5 or 6 * 50 MW datacenters with a serious amount of redundancy; read inefficiency

    Now let me come back and continue my earlier part about time zones.
    In case you would chose to use the grid as back up for your grid; you and the larger group miss the opportunity to actually use a sustainable energy source over a longer or shorter distance (depending on the grid of micro systems connected to the supergrid) and yes with the inefficiency but without the use of gas or oil etc.
