"How does solar energy work when there's no sun?" has been a question for pretty much about as long as solar energy has been a thing.

Of course people wouldn't want solar panels on their houses if installing them meant that, come sunset, the movie they were watching suddenly shut off, forcing them to read by candlelight like colonial settlers. Making solar power a viable option, even when the sun sets or disappears behind some clouds, was one of the first things scientists and engineers had to figure out.

When the first devices that could capture the sun's energy were invented, they weren't very efficient.

Much like touch screens or video chatting or Dorito-flavored taco shells, solar power is one of those perfect ideas that took a while to get just right. Believe it or not, the earliest solar devices were introduced in the 1800s.

In 1878, Augustin Mouchot invented a device that could freeze water using the concentrated power of the sun. It was a cool experiment but not exactly reasonable or viable options for large-scale energy production.

Mouchot won a gold medal at the Universal Exhibition in Paris for his invention, but his device was gigantic, and coal was quickly becoming the go-to for efficient energy, so it didn't catch on.

The other downside to his invention? The solar-powered water-freezer only worked on (you guessed it) sunny days. But, that was 1878. Things have changed a lot since then.

Over the last century, the efficiency and feasibility of solar power has dramatically increased, and it's getting better every day.

Just look at this fun, easy-to-read chart!

I know, I know, it's a lot to take in. Just know that it's showing you that since 1975, we've gotten better and better at efficiently converting the sun's rays into energy that can power our homes, businesses, and even a few cars and planes.

So how does solar energy keep providing power when the sun goes down?

The answer is pretty simple: storage.

Today's solar panels are designed to soak up more energy from the sun than we actually need and store it for later.

The way they do it is pretty amazing. Photons (aka light particles) hit the solar panel really hard — so hard that electrons (aka what electricity is made of) get knocked loose. Then the solar panel guides those loose electrons into a battery or superconductor that can store them. If an area has a reliable electricity grid, homeowners can just hook their solar panels right up to it. For them, nothing changes from their normal source of power except (usually) a smaller electricity bill.

A lot of people don't realize that going solar doesn't have to mean going "off grid," says Dan Whitson, solar manager for Green Audit USA in Long Island, N.Y.

"The grid is pretty reliable here, so battery options aren’t necessarily cost-effective on Long Island," Whitson explained over the phone. "But that’s something we have to explain to homeowners that, you know, you’re still going to be connected to the grid even though you’ve gone solar."

If there are solar panels on your roof, it's not like your PlayStation is plugged directly into them. The solar panels run into your regular power lines and help offset some of the energy cost, or they run into a box that will store the electricity, quite literally, for a rainy day.

Solar farms are power-plant-scale versions of this concept.

They can be built in the middle of a desert where the sun is incredibly powerful and cloudy days are rare. The panels can even pivot automatically to follow the sun's path across the sky.

After the panels soak up as much energy as they can, the energy is transported to nearby cities. There's a solar farm in Austin, Texas, that produces enough power for 5,000 homes and offsets over 1 billion pounds of carbon dioxide emissions.

Oh and, yes, solar panels can still collect energy on cloudy days. They're just not as efficient about it.

That's because clouds don't block all the sunlight, just some of it. If you walk outside on a cloudy day and can still see, that's because there's still sunlight, even if it's a bit more muted than usual.

That's where storage and the grid come in. Energy companies rely on the grid to offset any dips in production they might experience on a cloudy day.

"All of the reputable solar production calculators out there take in 20 to 30 years of weather data based on region," Whitson said. "So they can predict how much sun you’re going to get throughout the course of a year. Most projections are taking into consideration that it’s not going to be sunny every day."

Also, as previously mentioned, efficiency is one of the key things scientists are constantly trying to improve about solar panels.

"How does solar energy work when there's no sun?" is a simple question that cuts right to the core of a pretty huge idea.

It's the type of question that scientists, engineers, researchers, and experts around the world have to ask every single day in order to get better at what they're doing.

The energy in a hospital can sometimes feel overwhelming, whether you’re experiencing it as a patient, visitor or employee. However, there are a few one-of-a-kind individuals like Elaine Ahn, an operating room registered nurse in Diamond Bar, California, who thrive under this type of constant pressure.

If you know how to fix this tape, you grew up in the 1990s.

There are a lot of reasons to feel a twinge of nostalgia for the final days of the 20th century. Rampant inflation, a global pandemic and political unrest have created a sense of uneasiness about the future that has everyone feeling a bit down.

There’s also a feeling that the current state of pop culture is lacking as well. Nobody listens to new music anymore and unless you’re into superheroes, it seems like creativity is seriously missing from the silver screen.

But, you gotta admit, that TV is still pretty damn good.

A lot of folks feel Americans have become a lot harsher to one another due to political divides, which seem to be widening by the day due to the power of the internet and partisan media.

Teens of today live in a totally different world than the one their parents grew up in. Not only do young people have access to technologies that previous generations barely dreamed of, but they're also constantly bombarded with information from the news and media.

Today’s youth are also living through a pandemic that has created an extra layer of difficulty to an already challenging age—and it has taken a toll on their mental health.

According to Mental Health America, nearly 14% of youths ages 12 to 17 experienced a major depressive episode in the past year. In a September 2020 survey of high schoolers by Active Minds, nearly 75% of respondents reported an increase in stress, anxiety, sadness and isolation during the first six months of the pandemic. And in a Pearson and Connections Academy survey of US parents, 66% said their child felt anxious or depressed during the pandemic.

However, the pandemic has only exacerbated youth mental health issues that were already happening before COVID-19.

“Many people associate our current mental health crisis with the pandemic,” says Morgan Champion, the head of counseling services for Connections Academy Schools. “In fact, the youth mental health crisis was alarming and on the rise before the pandemic. Today, the alarm continues.”

Mental Health America reports that most people who take the organization’s online mental health screening test are under 18. According to the American Psychiatric Association, about 50% of cases of mental illness begin by age 14, and the tendency to develop depression and bipolar disorder nearly doubles from age 13 to age 18.

Such statistics demand attention and action, which is why experts say destigmatizing mental health and talking about it is so important.

“Today we see more people talking about mental health openly—in a way that is more akin to physical health,” says Champion. She adds that mental health support for young people is being more widely promoted, and kids and teens have greater access to resources, from their school counselors to support organizations.

Parents are encouraging this support too. More than two-thirds of American parents believe children should be introduced to wellness and mental health awareness in primary or middle school, according to a new Global Learner Survey from Pearson. Since early intervention is key to helping young people manage their mental health, these changes are positive developments.

In addition, more and more people in the public eye are sharing their personal mental health experiences as well, which can help inspire young people to open up and seek out the help they need.

“Many celebrities and influencers have come forward with their mental health stories, which can normalize the conversation, and is helpful for younger generations to understand that they are not alone,” says Champion.

That’s one reason Connections Academy is hosting a series of virtual Emotional Fitness talks with Olympic athletes who are alums of the virtual school during Mental Health Awareness Month. These talks are free, open to the public and include relatable topics such as success and failure, leadership, empowerment and authenticity. For instance, on May 18, Olympic women’s ice hockey player Lyndsey Fry will speak on finding your own style of confidence, and on May 25, Olympic figure skater Karen Chen will share advice for keeping calm under pressure.

Family support plays a huge role as well. While the pandemic has been challenging in and of itself, it has actually helped families identify mental health struggles as they’ve spent more time together.

“Parents gained greater insight into their child’s behavior and moods, how they interact with peers and teachers,” says Champion. “For many parents this was eye-opening and revealed the need to focus on mental health.”

It’s not always easy to tell if a teen is dealing with normal emotional ups and downs or if they need extra help, but there are some warning signs caregivers can watch for.

“Being attuned to your child’s mood, affect, school performance, and relationships with friends or significant others can help you gauge whether you are dealing with teenage normalcy or something bigger,” Champion says. Depending on a child’s age, parents should be looking for the following signs, which may be co-occurring:

  • Perpetual depressed mood
  • Rocky friend relationships
  • Spending a lot of time alone and refusing to participate in daily activities
  • Too much or not enough sleep
  • Not eating a regular diet
  • Intense fear or anxiety
  • Drug or alcohol use
  • Suicidal ideation (talking about being a burden or giving away possessions) or plans

“You know your child best. If you are unsure if your child is having a rough time or if there is something more serious going on, it is best to reach out to a counselor or doctor to be sure,” says Champion. “Always err on the side of caution.”

If it appears a student does need help, what next? Talking to a school counselor can be a good first step, since they are easily accessible and free to visit.

“Just getting students to talk about their struggles with a trusted adult is huge,” says Champion. “When I meet with students and/or their families, I work with them to help identify the issues they are facing. I listen and recommend next steps, such as referring families to mental health resources in their local areas.”

Just as parents would take their child to a doctor for a sprained ankle, they shouldn’t be afraid to ask for help if a child is struggling mentally or emotionally. Parents also need to realize that they may not be able to help them on their own, no matter how much love and support they have to offer.

“That is a hard concept to accept when parents can feel solely responsible for their child’s welfare and well-being,” says Champion. “The adage still stands—it takes a village to raise a child. Be sure you are surrounding yourself and your child with a great support system to help tackle life’s many challenges.”

That village can include everyone from close family to local community members to public figures. Helping young people learn to manage their mental health is a gift we can all contribute to, one that will serve them for a lifetime.

A recent (and fairly insensitive) sketch from “Saturday Night Live” said it best regarding the widespread fixation many have on the Johnny Depp and Amber Heard trial:

“It’s not the most pertinent story of the moment, but with all the problems in the world, isn’t it nice to have a news story we can all collectively watch and say ‘glad it ain't me?’”

Schadenfreude, celebrity fascination and previously inaccessible information now being at our fingertips is a potent combination in this trial, making amateur lawyers and psychologists of all who feel compelled to unleash their hot takes. And though the right to converse and speculate exists, is it always in our best interests to do so? Especially when it means potentially spreading misinformation, or at the cost of empathy and compassion?
