Chart 1 of 2 · Banks
How much money did the banks that failed each year hold?
The interactive chart needs JavaScript. The numbers are on the chart's page.
The five banks that failed in 2023 held $532 billion in assets, and in 2008 Washington Mutual and 24 other failed banks held $372 billion. In 1989, at the height of the savings-and-loan crisis, 530 failed banks and thrifts held $164 billion. Banks that failed in 2025 held $126,404,000. These are dollars of the day, not adjusted for inflation, and assets are what each bank owned (mostly loans and bonds) at its last report before it failed. Depositors lose money only on accounts above the insurance limit; failed banks are usually sold to other banks.

Where does US electricity come from?
The interactive chart needs JavaScript. The numbers are on the chart's page.
In 2025 natural gas made 40.8% of US electricity, followed by nuclear (17.7%) and coal (16.6%). Wind made 10.5% and solar 6.7%. Solar counts only utility-scale plants, not rooftop panels, and the 2025 figures are preliminary.
How to read this chart
Each bar is one energy source's share of all the electricity made in the U.S. in a year, so the bars add up to about 100%. The bars start at zero, so a bar twice as long means twice the share. Solar counts only large power plants, not panels on rooftops.
Questions to discuss
- Which source makes the most electricity? About how many times more than the smallest bar?
- Which of these sources burn fuel and which don't? What share of electricity comes from each group?
- Why might a chart of this kind look different in your state than for the whole country?
