I grew up less than 15 miles away from the Limerick Nuclear Generating Station, located on the banks of the Schuylkill River northwest of the city of Philadelphia. Our house sat on the north-facing slope of the Great Valley and the cooling towers of Limerick were a ridge line and river valley away from view. But on a clear day, you can see the puffy, billowy clouds of steam rising over the distant horizon—Limerick is splitting the atom.
We all know—or should by now—burning coal, oil, and gas are not terribly great for the planet. They emit carbon dioxide and other gasses that warm the Earth. But the white columns rising over the Schuylkill are water. Fissile uranium is more dense than coal, oil, or gas. And not just by a wee bit. But by orders of magnitude. Splitting the atom provides mankind with enormous amount of energy.
And we need energy. This summer was hot. And I don’t like it hot. Consequently, my air con ran almost nonstop. And I am not the only one. But whence comes all the electricity to power those units? Yes, we can get electricity from the sun, the wind, and the water. But what about when the clouds block the sun? Or the hot, sticky summer air refuses to stir? Or the parched earth has sucked the water from the reservoir?
The uranium atom can still be split, and at a reliable rate. That makes it great to provide a high amount of electricity that can be augmented by the sun, the wind, and the water when conditions permit.
However, in recent years, the cost of oil and gas declined thanks to fracking, and the business cost to run coal plants lowered as environmental standards disappeared. The economics of running nuclear power plants made them less viable than carbon-spewing options. Electricity providers started shutting nuclear plants down.
Things have changed, though. As we run more air con, we need more electricity. As we run more electric busses and trains, we need more electricity. As we charge more electric cars, we need more electricity. As we run more servers for bitcoin mining or AI farms, we need more electricity.
We need more electricity. A lot more.
And so the economics of electricity is changing. The Wall Street Journal had a great article about the re-opening of nuclear plant in Michigan. It included some really nice photographs of the control room and the turbine room. But, the reason we are talking about it here today because the article includes a few diagrams and illustrations. This one caught my attention.
First, I really enjoy how the United States is reduced to a grey outline. Perhaps a very faint grey could have been used to infill the states, but here I think white works best because of the use of the light and medium greys for active plants.
The active plants—not the focus of the article—are in those greys, whilst the decommissioned and -ing plants are in tints of red. What I struggled with a long time ago when I made an infographic about southeastern Pennsylvania’s electricity generation was how to show the different plants at a single facility.
Ultimately, I listed each plant by name then an icon representing the type of fuel, because not every plant uses all the same type of fuel. Eddystone Generating Station just south of Philadelphia used both natural gas/oil plants and two coal plants, though those were retired in the 2010s.
Here the designer, not needing to label each plant and aided by the fact each plant is nuclear, simply encloses the dots within a container. Palisades, the plant in question, receives a thicker, black stroke to call it out against the rest of the plants.
Credit for the piece goes to, I think Adrienne Tong. She is credited for a different graphic in the article, but not the one I highlighted, so I’ll give her the credit unless and until someone else gets the credit.
