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…

Electrical conductivity: energy transition materials?

Electrical conductivity of energy transition materials is tabulated in this data-file. ‘The action’ takes place in the range of 10^-8 to 10^-3 Ohm-meters, including silver in solar cells, copper in renewables and EVs, aluminium transmission lines, batteries, and solar semiconductors.

Data-centers: the economics?

The capex costs of data-centers are typically $10M/MW, with opex costs dominated by maintenance (c40%), electricity (c15-25%), labor, water, G&A and other. A 30MW data-center must generate $100M of revenues for a 10% IRR, while an AI data-center in 2024 may need to charge $5/EFLOP of compute.
