How Virtualization Can Reduce Organisation’s Energy Costs
Virtualization can enable cost savings for organizations in multiple ways. This article explores those instances and points out how the overall power savings from virtualization can boost the environmental credentials of the private and public institutions that adopt it.
Each year, organizations devote a substantial amount of their budget to providing power for their operations. Energy costs are on the rise, and so is its consumption. With companies and public agencies running on an increasing number of devices, costs are expected to trend upward still.
The Nigerian context brings an extra dimension to the situation with energy costs in the country. For most businesses, power from the public grid isn’t enough. They often have to augment it with expensive alternatives. One estimate puts the total annual spend on power by businesses at ₦5 trillion.
Given this situation, it’s easy to see why businesses are on the lookout for legitimate ways to cut their power costs. Virtualization technology provides them with an effective way to do just that.
What Is Virtualization?
Virtualization refers to the creation of a virtual version of an actual thing, including Operating Systems, servers, storage devices, and other computer platforms and network resources.
The virtual versions sit atop the actual component and run just like them. Virtualization is done by deploying software that divides the physical resource into multiple virtual instances.
Here’s an example. Given a single physical server, multiple virtual servers could be created to run atop that server, and work just like it. Each of those virtual servers will perform the same functions that a single physical server would.
The same sort of thing happens with virtual Operating Systems. If you have virtualization software on your computer, you could create multiple Operating Systems—called Virtual Machines –that would run alongside the single Operating System that the computer previously had.
This ability to run several instances of a single component is at the core of the cost savings that virtualization can guarantee.
In the following sections, we explore some of the ways by which virtualization achieves lower costs for the organizations that adopt it.
Virtualization and Server Consolidation
Datacenters consume a lot of electricity. One widely cited report from 2018 (contained in the journal Science) suggests that they take up about 205 terawatt-hours of electricity annually—that’s about 1% of electricity consumed worldwide each year.
It follows that thanks to the energy costs associated with them, datacenters cost a lot to maintain.
A greater part of that expense–40% in one report–comes from running servers. Considering that many servers only have a single application running on them per time, it’s clear that a lot of spending is going into keeping those applications up. It also means that these servers are sitting idle most of the time, adding even more expense for little or no workloads.
With virtualization, these costs can be cut significantly. Virtualization enables the consolidation of the number of servers in a data center, enabling businesses to run several applications and Operating System workloads on a single server. In many cases, a company could have ten workloads running on one server; but it’s possible to have several times that number on one server.
This consolidation translates to a reduction in the number of servers needed, and a substantial increase in the utilization of server capacity. Capacity use could increase from about 15% (which is typical) to as much as 80%. Energy savings may increase by up to 80%, and energy costs are cut by a significant amount.
Scalability and Tailoring Resources to Current Needs
Energy costs can increase or decrease depending on the demand placed on the resources that consume power. These variations may occur over short periods, such as hours within a day. They could also be longer-term, such as the growth of a company.
If an organization experiences any of these instances, it may have to spend a lot on acquiring new capabilities. Its response in any of these cases may also be slowed down due to hardware handling issues and associated costs.
Virtualization can enable organizations to scale resources quickly and meet growing demand. Whether the demand on resources fluctuates over a short period, or resources have to be matched to company growth, creating virtual versions of those resources can take care of those needs.
Often, businesses may maintain ‘excess capacity’ just so they can utilize that capacity when the occasion calls for it. This happens when they are principally dependent on hardware or other actual components, and less on virtual versions of them. With virtualization, they can power on or power off capacity, and save the cost of dormant resources.
Virtualization’s Impact on the Environment
By reducing the amount of energy that has to be consumed per device, virtualization shrinks the potential impact that their use could have on the environment.
By one estimate, each server that is virtualized saves 7,000kWh of electricity and four tons of carbon dioxide emission per year. It cuts down the amount of space that’s required in a data center, thus reducing both the cost of managing it and its possible impact on the environment.
Another way in which virtualization helps mitigate the environmental impact of technology is its cutting down on hardware that needs to be decommissioned at the end of its lifespan. Electronic waste is known to be a major environmental hazard, and the failure to properly dispose of them could mean that they become a physical pollutant. If companies opt for virtualization instead of acquiring new hardware, they could drive down the number of hardware that will eventually be decommissioned.

Dr. Olubunmi Tunji-Ojo, minister of Interior, has announced the launch of an Online Visa Approval Center to eliminate bureaucratic bottlenecks and reduce corruption in the visa application process.
Commissioned by the President in December, the new system ensures that applicants no longer need to visit a visa office, know anyone in the system, or lobby for approvals.
At a stakeholders’ sensitisation workshop on the implementation of the Nigeria Visa Policy (NVP) 2025, yesterday in Abuja, Dr. Tunji-Ojo said the visa is considered a very important document by the government because it is an instrument of migration management and an instrument of economic development.
The minister explained that Nigeria has to strike a delicate balance between national security and, of course, the ease of migration.
“And we think that it’s something that we can do and something we will do.
“We don’t have a physical Visa Approval Center. If you apply for a Nigerian visa anywhere in the world, you do so online. We process it here in Nigeria, and if approved, you receive your e-visa in your email,” he explained.
To enhance efficiency, the government has set a 48-hour deadline for processing e-visas.
“It is unprofessional and unacceptable for the Nigeria Immigration Service not to approve or provide feedback within 48 hours,” the minister stated.
“It breaks my heart that people need to lobby to even get visas to Nigeria. It shouldn’t be so. It shouldn’t be.
“For anybody that is qualified, for anybody that wants to do legitimate activities in Nigeria, such people should be able to come to Nigeria easily. And this is why we are opening our space. Mr. President is interested in foreign direct investments.”
Further, he said Nigeria is interested in partnering with the rest of the world to develop its economy but, “We can’t do that when we allow bottlenecks to hold us down. So these reforms, basically, are aimed at opening our space, enhancing national security, and we hope that the primary responsibilities of the visa scheme will be achieved.”
Kemi Nandap, controller general, Nigeria Immigration Service (NIS), said the NIS would fully digitize its e-visa platform and reduce visa classifications from 79 to 44 to enhance accessibility, transparency, and efficiency in the new visa policy.
She said, “At the core of this policy is the new e-visa platform—a fully digitized, centralized system that revolutionizes how foreign nationals interact with our country’s entry procedures. As part of this transformation, the Nigerian Visa Policy 2024 underwent a comprehensive review, resulting in a significant reduction in visa classifications from 79 to 44.
“These categories have been logically grouped to simplify procedures, reduce complexities, and greatly improve the user experience. Importantly, we have maintained the original purpose and intent of each visa class throughout this reform.”
Mr. Takao Shimokawa, director general, Economic Development Department at the Japan International Cooperation Agency (JICA) has visited the National Information Technology Development Agency (NITDA) to discuss the forthcoming launch of the Nigeria-Japan Startup Hub Project.

This is in a strategic move to strengthen Nigeria’s startup ecosystem.
During his visit, Mr. Shimokawa was received by Mr. Dejo Olawunmi, director of IT Infrastructure Solutions at NITDA.
Their discussions focused on advancing technological innovation, fostering entrepreneurship, and enhancing venture capital development to support early-stage startups in Nigeria.
The Nigeria-Japan Startup Hub Project is designed to provide Nigerian startups with access to Japanese expertise, mentorship, and investment opportunities.
The initiative aims to create a collaborative environment where local entrepreneurs can scale their businesses by leveraging Japan’s advanced technology and business models.
By bridging Nigerian startups with Japanese investors and industry leaders, the project seeks to drive sustainable growth and innovation in Nigeria’s tech industry.
This partnership underscores the increasing economic and technological cooperation between the two nations, positioning Nigeria as a key player in the global startup landscape.
With the hub set to launch soon, stakeholders anticipate that it will provide critical resources for startups, enabling them to compete in the global market and contribute to Nigeria’s digital economy.
Kaspersky has identified and helped patch a sophisticated zero-day vulnerability in Google Chrome (CVE-2025-2783) that allowed attackers to bypass the browser’s sandbox protection system.
The exploit, discovered by Kaspersky’s Global Research and Analysis Team (GReAT), required no user interaction beyond clicking a malicious link and demonstrated exceptional technical complexity. Kaspersky researchers have been acknowledged by Google for discovering and reporting this vulnerability.
In mid-March 2025, Kaspersky detected a wave of infections triggered when users clicked personalised phishing links delivered via email. After clicking, no additional action was needed to compromise their systems.
Once Kaspersky’s analysis confirmed that the exploit leveraged a previously unknown vulnerability in the latest version of Google Chrome, Kaspersky swiftly alerted Google’s security team. A security patch for the vulnerability was released on March 25, 2025.
Kaspersky researchers dubbed the campaign “Operation ForumTroll”, as attackers sent personalised phishing emails inviting recipients to the “Primakov Readings” forum. These lures targeted media outlets, educational institutions, and government organisations in Russia.
The malicious links were extremely short-lived to evade detection, and in most cases ultimately redirected to the legitimate website for “Primakov Readings” once the exploit was taken down.
The zero-day vulnerability in Chrome was only part of a chain that included at least two exploits: a still-unobtained remote code execution (RCE) exploit that apparently launched the attack, while the sandbox escape discovered by Kaspersky constituted the second stage. Analysis of the malware’s functionality suggests the operation was designed primarily for espionage. All evidence points to an Advanced Persistent Threat (APT) group.
“This vulnerability stands out among the dozens of zero-days we’ve discovered over the years,” said Boris Larin, principal security researcher at Kaspersky GReAT. “The exploit bypassed Chrome’s sandbox protection without performing any obviously malicious operations – it’s as if the security boundary simply didn’t exist.
The technical sophistication displayed here indicates development by highly skilled actors with substantial resources. We strongly advise all users to update their Google Chrome and any Chromium-based browser to the latest version to protect against this vulnerability.”
Google has credited Kaspersky for uncovering and reporting the issue, reflecting the company’s ongoing commitment to collaboration with the global cybersecurity community and ensuring user safety.
Kaspersky continues to investigate Operation ForumTroll. Further details, including a technical analysis of the exploits and malicious payload, will be released in a forthcoming report once Google Chrome user security is assured.
Meanwhile, all Kaspersky products detect and protect against this exploit chain and associated malware, ensuring users are shielded from the threat.
This discovery follows Kaspersky GReAT’s previous identification of another Chrome zero-day (CVE-2024-4947), which was exploited last year by the Lazarus APT group in a cryptocurrency theft campaign.
In that case, Kaspersky researchers found a type confusion bug in Google’s V8 JavaScript engine that enabled attackers to bypass security features through a fake cryptogame website.
