About Cabling Installation & Maintenance

Our mission: Bringing practical business and technical intelligence to today's structured cabling professionals

For more than 30 years, Cabling Installation & Maintenance has provided useful, practical information to professionals responsible for the specification, design, installation and management of structured cabling systems serving enterprise, data center and other environments. These professionals are challenged to stay informed of constantly evolving standards, system-design and installation approaches, product and system capabilities, technologies, as well as applications that rely on high-performance structured cabling systems. Our editors synthesize these complex issues into multiple information products. This portfolio of information products provides concrete detail that improves the efficiency of day-to-day operations, and equips cabling professionals with the perspective that enables strategic planning for networks’ optimum long-term performance.

Throughout our annual magazine, weekly email newsletters and 24/7/365 website, Cabling Installation & Maintenance digs into the essential topics our audience focuses on.

  • Design, Installation and Testing: We explain the bottom-up design of cabling systems, from case histories of actual projects to solutions for specific problems or aspects of the design process. We also look at specific installations using a case-history approach to highlight challenging problems, solutions and unique features. Additionally, we examine evolving test-and-measurement technologies and techniques designed to address the standards-governed and practical-use performance requirements of cabling systems.
  • Technology: We evaluate product innovations and technology trends as they impact a particular product class through interviews with manufacturers, installers and users, as well as contributed articles from subject-matter experts.
  • Data Center: Cabling Installation & Maintenance takes an in-depth look at design and installation workmanship issues as well as the unique technology being deployed specifically for data centers.
  • Physical Security: Focusing on the areas in which security and IT—and the infrastructure for both—interlock and overlap, we pay specific attention to Internet Protocol’s influence over the development of security applications.
  • Standards: Tracking the activities of North American and international standards-making organizations, we provide updates on specifications that are in-progress, looking forward to how they will affect cabling-system design and installation. We also produce articles explaining the practical aspects of designing and installing cabling systems in accordance with the specifications of established standards.

Renewable energy accounted for 92% of all power growth globally in 2024

Renewable energy accounted for 92% of all power growth globally in 2024

Countries around the world added 585 gigawatts of renewable energy capacity in 2025, accounting for 92.5% of all power growth globally, a report out this week from the International Renewable Energy Agency says. That figure equated to an annual growth rate of a record high 15.1%, the agency said.

Despite the record increase, renewable energy growth is still not moving fast enough to satisfy the global goal to triple renewable capacity to 11.2 terawatts by 2030. The energy agency said to achieve that goal renewable capacity will need to grow at least 16.6% each year until then.

“The continuous growth of renewables we witness each year is evidence that renewables are economically viable and readily deployable,” said IRENA Director-General Francesco La Camera in a press release. “Each year they keep breaking their own expansion records, but we also face the same challenges of great regional disparities and the ticking clock as the 2030 deadline is imminent.”

The regional disparities reflect that fact that most of the worldwide growth in renewables is coming from Asia, and China in particular. The IRENA data show China accounted for almost 64% of the global added capacity while Central America and the Caribbean contributed just 3.2%. Altogether the G-20 countries, which includes China and the U.S., accounted for 90% of the new capacity.

“Renewable energy is powering down the fossil fuel age. Record-breaking growth is creating jobs, lowering energy bills and cleaning our air. Renewables renew economies,” United Nations Secretary-General António Guterres told IRENA. “But the shift to clean energy must be faster and fairer – with all countries given the chance to fully benefit from cheap, clean renewable power.”

Solar and wind energy continued to expand the most, jointly accounting for 96.6% of all net renewable additions in 2024. Over three-quarters of the capacity expansion was in solar energy which increased by 32.2%, reaching 1,865 gigawatts, followed by wind energy which grew by 11.1%.

Among the other highlights in the report:

  • Solar: Solar photovoltaics increased by 451.9 GW last year. China alone added 278 GW to the total expansion, followed by India (24.5 GW).
  • Hydropower (excluding pumped storage hydropower): Capacity reached 1,283 GW, demonstrating a notable rebound from 2023, driven by China. Ethiopia, Indonesia, Nepal Pakistan, Tanzania and Viet Nam added more than 0.5 GW each.
  • Wind: Wind energy expansion declined slightly, to a total of 1,133 GW capacity by the end of 2024. Expansion was once again dominated by China and the United States.
  • Bioenergy: Expansion rebounded in 2024, with an increase of 4.6 GW of capacity compared to an increase of 3.0 GW in 2023. The growth was driven by China and France with 1.3 GW of additions each.
  • Geothermal: Geothermal energy increased by 0.4 GW overall, led by New Zealand, followed by Indonesia, Türkiye, and the US.
  • Off-grid electricity (excluding Eurasia, Europe and North America): capacity expansion nearly tripled, growing by 1.7 GW to reach 14.3 GW. Growth was dominated by off-grid solar energy which reached 6.3 GW by 2024.
