Dinesh Nirmal, General Manager, IBM Automation, says: "IT professionals have what is in theory a simple mandate, to maintain and improve IT operations. But in the face of labour shortages, geographic disruptions, security threats, demand spikes, environmental pressures and more, we know that delivering on this mandate is anything but simple, in fact the complexity is only growing."
"IBM's collaboration with Flexera adds to our automation portfolio and complements our strategic acquisitions of Turbonomic and Instana, as well as years of AI research and development to provide organisations with a one-stop shop of IT and business automation capabilities designed to meet these complex challenges."
7. Honeywell
CEO: Vimal Kapur
Founded: 1906
Headquarters: North Carolina, United States
Honeywell says that its digital efficiency solutions help customers reduce energy waste, optimise operations and manage carbon impact.
Amongst its range of technologies, Honeywell provides customers with the ability to track energy usage through its Connected Power Solution.
The technology allows customers to control energy usage from plug level. This means building managers can autonomously power down unused outlets based on space usage data.
"With Connected Power, Honeywell is empowering building decision makers to address the invisible energy waste at the device level by helping to ensure energy is only used when it is really needed," says Billal Hammoud, President and CEO of Honeywell's Building Automation.
6. Microsoft
CEO: Satya Nadella
Founded: 1975
Headquarters: Washington, United States
Microsoft provides its technology solutions for companies within the power and utilities industries.
The technology Microsoft manufacturers can provide real time alerts to field service dispatchers, which allows for high productivity rates and collaboration.
Its technology can also support the prevention of breakdowns of equipment using predictive maintenance, this improves energy efficiency as it can identify the best time for updating services.
Microsoft provides various software to improve energy efficiency such as Azure Data Manager for energy, Azure Digital Twins and Azure IoT.
5. ABB
CEO: Morten Wierod
Founded: 1988
Headquarters: Zürich, Switzerland
ABB provides several technologies that support energy efficiency, saying that it is a core objective in the company's product design.
The company manufactures tech such as energy metres which allows customers to reduce energy costs and enhance the efficiency of electrical use.
Erich Labuda, Division President, ABB Motion Services, says: “Energy efficiency isn’t an optional upgrade — it’s a critical one.
“Greater energy efficiency not only enhances energy independence but also spurs economic growth, making the adoption of these solutions a clear and sensible choice.”
4. Amazon Web Services
CEO: Matt Garman
Founded: 2002
Headquarters: Washington, United States
AWS provides a comprehensive cloud service that offers customers the ability to optimise efficiency, renewable energy development, manage distributed energy resources and monitor emissions.
The cloud service has been adopted by various companies in the energy sector such as EDF, Engie and Octopus Energy to support the optimisation of operations.
Global leaders in the energy sector have tailored AWS's cloud services to meet the individual needs of companies, such as Octopus energy building its energy technology, Kraken.
The platform supports operational efficiency and is designed to provide customers with cheaper renewable energy by supporting smarter grids.
3. Siemens
CEO: Roland Busch
Founded: 1847
Headquarters: Munich, Germany
Siemens has a core focus on smart energy solutions, creating modular software that supports power utilities through the energy transition.
The company provides companies such as Elvia with technology like the SaaS, LV Insights X, which automates processes and handles grid complexity.
Technology, such as what Siemens provides for Elvia, improves energy efficiency as it allows increased flexibility and provides the company with more oversight over the grid.
Sabine Erlinghagen, CEO Siemens Grid Software, says: “At Siemens Grid Software, we are committed to accelerating the energy transition.
“Our low voltage software, LV Insights X, empowers grid operators to gain full transparency over their grid and increase capacity by identifying critical segments.
“Having now been deployed at Elvia, the software will enable the company to tackle its most pressing challenges, gain valuable insights to make fast decisions and increase customer satisfaction.”
2. Schneider Electric
CEO: Olivier Blum
Founded: 1836
Headquarters: Rueil-Malmaison, France
Schneider Electric has created an automated technology that aims to help maximise savings within homes by providing energy efficiency solutions.
The thermostat, Wiser, has an intuitive dashboard that allows homeowners to control energy use, alongside integrated renewable generation and efficiency boosting functions.
Frédéric Godemel, Executive Vice President for Energy Management at Schneider Electric, says: “A global survey we conducted at Schneider Electric found that 84% of respondents now consider energy efficiency their top home improvement priority.
“Many people take small steps — like switching off lights or unplugging unused devices — but fewer are implementing high-impact solutions.
“For example, heating and cooling account for most home energy use, yet adjusting thermostats efficiently is often overlooked.
“Smart automation can help close this gap, ensuring homes use the right amount of energy at the right time whilst delivering maximum control and comfort.”
1. Google
CEO: Sundar Pichai
