Energy intensity of fiber optic cables?
What is the energy intensity of fiber optic cables? Our best estimate is that moving each GB of internet traffic through the fixed network requires 40Wh/GB of energy, across 20 hops, spanning 800km and requiring an average of 0.05 Wh/GB/km. Generally, long-distance transmission is 1-2 orders of magnitude more energy efficient than short-distance.

Fiber optic data transmission costs?
The costs of fiber optic data transmission run at $0.25/TB per 1,000km in order to earn a 10% IRR on constructing a link with $120 per meter capex costs. Capex is 85% of the total cost. This data fiber breaks down the costs of fiber optic data transmission from first principles, across capex, utilization, electricity…

Overview of lasers: by type, market size and efficiency?
The global laser market is worth $20bn pa, of which half comprises diode lasers mainly used for fiber-optic communications and around 30% is fiber lasers mainly used for cutting, welding and heat-treating materials. These two laser types dominate because of their high, 30-80% efficiencies. This data-file is a brief overview of lasers.

Photons vs electrons: laser quest?
Some commentators say the 21st century will be the ‘age of the electron’. But in computing/communications, the photon has long been displacing the electron. This 17-page note gives an overview. It matters as moving data is 50-90% of data center energy use. We contrast fiber vs copper; and explore AI power, optical computing, and a…

Energy development times: first consideration to full production?
Full cycle development times tend to average c4-years for large solar projects, 6-years for large offshore wind, 7-years for new pipelines, 7-years for new oil and gas projects, 9-years for new LNG plants and 13-years for new nuclear plants. This data-file reviews 35 case studies.

Moving targets: molecules, electrons or bits ?!
New AI data-centers are facing bottlenecked power grids. Hence this 15-page note compares the costs of constructing new power lines, gas pipelines or fiber optic links for GW-scale computing. The latter is best. Latency is a non-issue. Thus AI reshapes the future of US shale, midstream and fiber-optics?

AI and sensors: case studies and examples?
The global sensor market is worth $230bn pa and likely accelerates due to the rise of AI. This data file has compiled 15-20 examples of AI systems integrating sensor data, as patented by industrial companies in 2024, to estimate what types of sensors, will be used in which contexts, and whether AI demand will surprise…

US shale: outlook and forecasts?
This model sets out our US shale production forecasts by basin. It covers the Permian, Bakken and Eagle Ford, as a function of the rig count, drilling productivity, completion rates, well productivity and type curves. US shale likely adds +1Mbpd/year of production growth from 2023-2030, albeit flatlining in 2024, then re-accelerating on higher oil prices?
