US Supreme Court Upholds Tennessee’s Ban on Gender-Affirming Care for Minors

US Supreme Court Upholds Tennessee’s Ban on Gender-Affirming Care for Minors

The US Supreme Court’s conservative majority on Wednesday upheld the state of Tennessee’s ban on gender-affirming care for minors.

In a 6–3 decision in United States v. Skrmetti, the justices found that Tennessee’s law is not unconstitutional. The central issue of the case was whether Tennessee’s ban violates the equal protection clause of the 14th Amendment, which states that the government cannot discriminate against individuals based on their race, gender, or other characteristics. The ruling does not affect states where gender-affirming care for youth remains legal, but establishes the precedent that states can ban this kind of treatment.

The lawsuit was brought to the court by three transgender teenagers and their parents, as well as a doctor, with the Biden administration’s Department of Justice joining the plaintiffs. They argued that the Tennessee law discriminates based on sex and gender status by denying medical care to transgender youth that is available to other minors. This is the first case the Supreme Court has taken up on the issue of gender-affirming care for minors.

Gender-affirming care includes a variety of medical services meant to help align a person’s body more closely with their gender identity. It can include hormone therapy, puberty blockers, and surgeries.

Tennessee enacted its law in 2023, which prohibits health care providers from prescribing medication or offering gender-affirming surgical procedures to minors whose gender identities are different from their assigned sex at birth. The law excludes procedures that address congenital defects or physical injuries, as well as gender-affirming medical care for minors whose gender identity conforms with their designated sex at birth. It means, for instance, that a cisgender boy with gynecomastia, a hormonal condition that causes enlarged male breast tissue, could receive medication or undergo surgery to remove breast tissue to conform to their gender identity, but a transgender individual could not receive the same treatment for gender dysmorphia.

Today’s Supreme Court ruling, delivered by Chief Justice John Roberts, maintains that Tennessee’s law is not discriminatory because it “prohibits healthcare providers from administering puberty blockers or hormones to any minor to treat gender dysphoria, gender identity disorder, or gender incongruence, regardless of the minor’s sex.” According to the justices, the Tennessee law does not exclude any individual from medical treatments based on their transgender status. “Rather, it removes one set of diagnoses—gender dysphoria, gender identity disorder, and gender incongruence—from the range of treatable conditions,” the ruling says.

Since 2021, more than two dozen states have adopted laws or policies that prohibit or severely limit gender-affirming care for people under the age of 18. Many of those states also penalize health care practitioners for providing or offering this type of care to minors. According to the health policy nonprofit KFF, 40 percent of trans youth between the ages of 13 and 17 live in a state that has enacted a policy against gender-affirming care.

Though several states were facing legal challenges to their bans, today’s Supreme Court decision means those laws will likely remain intact.

Leading medical organizations—including the American Medical Association, the American Academy of Pediatrics, the American Psychiatric Association, American College of Obstetricians and Gynecologists, and the World Health Organization—support access to gender-affirming care for transgender and gender-diverse youth, which they say is backed by scientific evidence. One study from 2022 surveyed nearly 12,000 transgender and nonbinary youth aged 13 to 24 and found that those who received gender-affirming hormone therapy had lower rates of depression, thoughts of suicide, and attempted suicide than those who had not received hormone therapy.

“Today’s Supreme Court decision is a devastating blow to transgender youth and the families who love them,” said Kelley Robinson, president of the Human Rights Campaign, an organization that promotes LGBTQ+ civil rights, in a statement. “Families may now have to make the heartbreaking choice to leave their state or split their families, or take on extensive financial burdens, in order to ensure that their kids can access medically necessary care.”

If you were thinking of seeing Minions & Monstersor at least taking your kid to see it, here’s something to sweeten the pot: George Lucas is in it.

Illumination head Chris Meledandri broke the news in a recent Collider interview, where he revealed the Star Wars creator is secretly a fan of Despicable Me’s chatty champions. “It was such a thrill to learn and share that with the team,” said Meledandri, “He’s among a very small group of people who the entire studio shares a level of respect for that is just off the charts.” Given Lucas’ affection for funny little guys, it makes sense that he loves the biggest little guys of our current movie era.

Now that they knew they had Lucas in their corner, the team decided what the hey, get him to do a voice for the movie. Meledandri said an “idea for a character” was born that fit the bill, and they got “a fast yes” when it was pitched. At time of writing, Illumination’s quiet on who Lucas will be, but it’s worth noting that Minions & Monsters takes place in the 1920s as the crew try to make their own movie. Lucas’ love for older films is apparent in Star Wars and Indiana Jones, so maybe he’ll be a director that ends up getting trampled by the Minions. Maybe he’ll even be one himself who just looks like a little yellow George Lucas, that’d be fun.

Look for Minions & Monsters to hit theaters on July 1.

With electricity costs soaring, home batteries have never looked so attractive. Whether you want to store the excess generated by your solar panels or simply buy electricity at the cheapest possible rate to use later when power is most expensive, a home battery can help. It’s never been easier to get a home battery installed, but this rapidly expanding market can be confusing, and there are several things to consider before you buy.

I’ve spent months researching home batteries, chatting to folks who use them, and then having one installed myself, and I have tips for anyone interested in getting a home battery of their own.

Why Would You Want a Home Battery?

There are several reasons you might want to invest in a home battery, and they are not mutually exclusive:

  • You want to store excess power from your solar panels.
  • You want to live off-grid.
  • You want to guard against power outages.
  • You want to buy electricity at a cheap rate and store it for use later.

Home batteries are a win-win, potentially benefiting power companies too, because battery storage is an essential part of grid balancing and can help manage and make the most of the intermittent power generated by renewables (solar, wind, waves).

How Do Home Batteries Work?

A home battery is like a big power bank for your home. But rather than lithium-ion, they tend to be lithium iron phosphate (LFP or LiFePO4), because it is safer, more durable, and less prone to thermal runaway. In other words, less likely to overheat and burst into flames. There are a few manufacturers working with sodium-ion (Na-ion) batteries, which are potentially cheaper, more environmentally friendly (they don’t require lithium), and perform better in the cold, but they are also larger and don’t last as long.

Home battery technology is often the same as you’ll find in electric vehicles. Some folks have even suggested employing EV batteries as home batteries. But there are potential issues with that, not least finding your car battery drained in the morning. EVs are also driving the technology forward toward solid-state batteries, which are smaller for the same capacity, safer as they don’t have liquid electrolytes inside, and longer lasting.

Many home batteries come in modular systems, so you can add the capacity you want, but they require an inverter to convert the DC (direct current) power stored to AC (alternating current) power you can use. Folks with solar panels, or those who plan to add them in the future, should opt for a hybrid inverter, which can also convert the power from the panels for use or storage.

Inverters have different power ratings in kilowatts (kW) that dictate how much power you can draw at any given moment. Households with modest needs may get by with a 3.6-kW inverter, but that limits your continuous draw to 3.6 kW. They usually have a peak load capability that goes higher, enabling you to pull more for a brief period. If you have high-demand appliances like an EV charger or heat pump, you will want at least 5 kW, and folks with larger demands or larger batteries will want to go higher (6 to 10 kW).

What Should I Look For?

There are several things to watch out for when buying a home battery:

  • Capacity: Measured in kilowatt-hours (kWh), this tells you how much total energy the battery can hold.
  • Power output: Measured in kilowatts (kW), this shows how much energy the battery and inverter can deliver at any moment.
  • Depth of discharge: This is how much of the battery’s capacity you can safely use without damaging it.
  • Efficiency: This is the percentage of the power you put into the battery that you can actually use, because some energy is always lost in the storage process.
  • Warranty: This is a guarantee about the minimum performance you can expect before a battery degrades (they all degrade over time), and it’s often stated in years and charging cycles (whichever comes first). For example, EcoFlow promises at least 70 percent capacity after 15 years or 6,000 charging cycles.

How Much Home Battery Do You Need?

It can be tricky to calculate how much battery capacity you need, and it depends on your use case. If you want to guard against outages or live off-grid, you must consider how much power you use over time and also the sum of your maximum power usage at any given moment to ensure your capacity in kWh and output in kW are enough. If the output is not high enough you may not be able to run power-hungry appliances at the same time, so you’ll have to think about how you use your power.

For folks like me, simply looking to buy at a cheaper rate to use when power is more expensive, any capacity will benefit you. But if you have a cheap six-hour rate overnight, for example, then you ideally want it to last for the other 18 hours. It makes sense to get as much as you can up-front because the installation costs are high. Even adding to modular systems later often requires professional installation to avoid voiding your warranty.

Do You Need Upgrades or Permission?

The home battery will connect to your main electrical panel via a cable, and it may require some upgrades. There was no room on my fuse board when I got a home battery installed, so they had to install a second breaker box.

Some inverters may require permission from your electric distribution utility or local distribution company. Here in Scotland, the distribution network operator must approve your inverter, but you can install and then notify up to 3.6 kW, whereas larger inverters require prior approval.

The home battery will connect to your main electrical panel via a cable, and it may require some upgrades. There was no room on my fuse board when I got a home battery installed, so they had to install a second breaker box.

Some inverters may require permission from your electric distribution utility or local distribution company. Here in Scotland, the distribution network operator must approve your inverter, but you can install and then notify up to 3.6 kW, whereas larger inverters require prior approval.
