Decarbonized supply chains: first invent the universe?
…that whatever CO2 was embedded in the input materials still shows through. “Translucent” might be used to connote a process that is almost transparent, but has still added some small…
Wind power: energy costs, energy payback and EROEI?
…observation from reviewing technical papers is that many have rough methodologies. Some are still basing numbers upon small, <1MW turbines, which are no longer representative. Conversely, others are incomplete, and…
Energy shortages: medieval horrors?
…same trend operated in reverse, as candles (made from animal fat) cost 2x more once transported into a city than they did the countryside. The rural economy revolved around small…
Power transmission: raising electrical potential?
…physics of power transmission are laid out on pages 5-7, with worked examples showing how the existing grid transmits relatively small power quantities over relatively low distances, but resistive power…
Wind and solar: cost of grid interconnection?
…wind projects joined the queue at peak in 2021!). We have also written a separate article on grid interconnection times. There is excellent granularity in the data-file, ranging from small…
HVDC transmission: leading companies?
…In other words, the space is relatively concentrated across this small group of companies, although the companies are themselves relatively un-concentrated, with just c30% of the average one’s revenues coming…
