Base load my friend. We also need steady, reliable, clean power when it’s dark and calm. Until we can accomplish seasonal grid storage of renewables, this is the less expensive option.

There are plenty of firming options (battery, pumped hydro, flywheels etc) which deliver reliability for a fraction of the price of this boondoggle. Not to mention a diverse portfolio of renewable technologies spread over a large geographical area is actually quite stable. When the sun isn’t shining in one area, the wind may be blowing or the sun shining in another area.

  • pumped hydro -> not exactly something that can be built anywhere and also not very cheap
  • battery -> huge environmental impact until we can get something like sodium based batteries
  • Flywheels, not exactly something that gets you through the night is it.

Those can only hold enough power for minutes or hours.

We need to be able to store power from the summer until the winter. Months. We need to store energy from when the sun is shining in July until it’s not in December.

The only possible way to do that now is to store it as hydrogen or hydrocarbons. That infrastructure is currently very lossy, expensive, and only hypothetical.

This idea they can only hold for minutes or hours is simply not true not to mention the entire premise is false. Only the cloudiest of days the solar panels produce 20% what they do on the sunniest days that means you only need to build out 5 times the expected output to always be able to produce what you need during sunny hourse. That means you only need to have battery backup for 16 hours. Something that’s completely feasible. The idea batteries can’t hold power for months isn’t true it’s that it’s not currently economical. How long do you think your electronics take to get from the plant to the store till you buy it and turn it on. If we’re talking about cost then let’s look at this plant. 1.1GW nuclear reactor costs 35 billion and 15 years. A solar farm built out to 5 times capacity would cost roughly 6 billion. Now triple that for battery costs if you want 24/7 electricity were on the order of 18 billion. That’s nearly half the cost and this is being very conservative assuming you want this to be a baseload supplier but will output way more most of the time. Now you will have nearly free electricity during most of the year that other industries could take advantage of like aluminum processing or something like that.

You don’t need power storage for months, if you combine different renewable sources and have power lines connecting different areas. Wind and solar complement each other usually.

You need to be able to bridge a few weeks though, because there will be gaps, but you don’t need to store solar power for half a year to make it. It is still a big issue, but no need to exaggerate.
