SOBRE ESTE EPISÓDIO
Ed Hoskins presents slides comparing renewables (onshore/offshore wind, solar PV, plus biomass and hydro) with gas, coal/lignite, and nuclear on productivity, EROEI, CO2 embedded in construction, land use, materials, build time, service life, and costs adjusted for capacity factors. He cites European capacity factors since 2010 (offshore ~32%, onshore ~20s, solar ~11%), a combined renewables average near 15% and declining since 2020, and a 2023 wind lull leaving large multi-day deficits. He argues storage to cover such gaps is infeasible, renewables require backup and expanded grids, wear out faster, and become far costlier once productivity is included; nuclear is most energy-productive. He criticizes Germany’s nuclear shutdown and questions CO2-driven policy.
