Internet energy consumption: data, models, forecasts?
This data-file forecasts the energy consumption of the internet, rising from 800 TWH in 2022 to 2,000 TWH in 2030 and 3,750 TWH by 2050. The main driver is the energy consumption of AI, plus blockchains, rising traffic, and offset by rising efficiency. Input assumptions to the model can be flexed. Underlying data are from…

Global electricity prices vs. CO2 intensities?
Retail electricity prices average 11c/kWh globally, of which 50-60% is wholesale power generation, 25-35% is transmission and 10-20% covers other administrative costs of utilities. The average CO2 intensity of the global average power grid is 0.45 kg/kWh. Variations are wide. And there is a -35% correlation between electricity prices vs CO2 intensities in different countries…

Aluminium producers: company screen?
Leading aluminium producers are reviewed in this data-file, across ten companies, producing half of the world’s global output. Scale ranges 1MTpa to 7MTpa. CO2 intensity of primary aluminium production ranges from 3 tons/ton to 17 tons/ton, in aggregate across these companies.

Cement costs and energy economics?
This data-file captures cement costs, based on inputs, capex and energy economics. A typical cement plant requires a cement price of $130/ton for a 10% IRR, on capex costs of $200/Tpa, energy intensity of 1,000 kWh/ton and CO2 intensity of 0.9 tons/ton. Cement costs can be stress tested in the data-file.

California electricity prices by hour?
In 2023, power grids with c20-30% solar variation tend to have intra-day spreads of 9c/kWh, between peak wholesale electricity prices at 8pm and trough prices at 10am. Unusually, night-time electricity prices are 40% higher than day-time prices. This data-file quantifies California electricity prices, on a wholesale basis, at a sample of grid nodes, looking hour…

MOSFETs: energy use and power loss calculator?
MOSFETs are fast-acting digital switches, used to transform electricity, across new energies and digital devices. MOSFET power losses are built up from first principles in this data-file, averaging 2% per MOSFET, with a range of 1-10% depending on voltage, switching, on resistance, operating temperature and reverse recovery charge.

Wind and solar: what CO2 abatement costs of renewables?
The costs of decarbonizing by ramping up solar and wind are highly dependent on context. The purpose of this data-file is to enable stress-testing of the CO2 abatement costs of renewables, in different contexts and at different grid penetrations. Our own estimate is that solar and wind can reach 40% of the global grid for…

Global energy demand by end use?
This data-file is a breakdown of global energy demand by end use, drawing across our entire research library, to disaggregate the global energy system across almost 50 applications, across transportation, heat, electricity, materials and manufacturing. Numbers, calculations, efficiencies and heating temperatures are in the data-file.
