I'm guessing much of that delivery cost is due to the additional energy transmission and storage infrastructure needed to incorporate intermittent energy from solar/wind. Solar and wind are extremely expensive when all costs are taken into account. One study found that the "true cost of using wind and solar to meet demand was $272 and $472 per MWh": [pdf]https://web.archive.org/web/20220916003958/https://files.americanexperiment.org/wp-content/uploads/2022/09/The-High-Cost-of-100-Percent-Carbon-Free-Electricity-by-2040-in-Minnesota.pdf https://web.archive.org/web/20220916003958/https://files.ame... Mind you, this could change if we get an economical way to generate hydrocarbon fuels from renewable electricity, so I'm certainly not pessimistic about solar/wind's long term prospects.
