If it’s not in use, turn it off

Image: Chris Haws

We start the list with this well-known advice: turn off the lights when nobody is in the room .

Additionally, switch off appliances completely rather than leaving them on standby, as standby mode continues to consume electricity. Most computers have energy-saving settings that automatically turn off the computer and screen after a period of inactivity.

2

Keep the temperature where you need it

Whenever you are heating or cooling a room, remember to close the doors and windows that connect to other unoccupied parts of the building . This way, the heating or cooling equipment you are using will not require more energy than is necessary to maintain the desired temperature where you are.

During cooler months, ensure your curtains or blinds are properly sealed to keep the cold out. In warmer months, keep your curtains closed during the day to prevent heat from entering.

3

Wash and dry clothes once the basket is full

Avoid using your washing machine when your laundry basket is only half full; instead, use it when you have accumulated a full charge. Also, remember to select the appropriate washing cycle to optimize energy use.

On a related note, clothes dryers consume a significant amount of energy, so consider hanging clothes outside to dry or using a fan to help dry them indoors.

4

Save energy in the kitchen

Your kitchen offers many energy-saving opportunities. The fridge, one of the most energy-intensive appliances, runs 24/7 for obvious reasons but measures can be taken to make it a more efficient device. The ideal fridge temperature for the fridge is between 35° and 38°F. Make sure the door seal is tight, with no gaps or cracks that allow cold air to escape.

As for cooking, always put frozen food in your fridge in the morning to thaw out and reduce cooking time in the evening. Whenever possible, use a microwave, as it consumes significantly less energy than an electric oven. Plan to cook more and have leftover meals for the next day or the week ahead. Keep leftover meals in the freezer for convenience and minimal waste.

Smart heating and cooling

Image: Everett Pachmann

It may be tempting to adjust the thermostat a degree or two above or below the recommended settings depending on the season, but there is good reason to avoid doing that. Every degree above 20 can increase your heating bill by up to 10%. In winter, set your thermostat between 18 and 20 degrees. In summer, aim for 26 degrees or higher.

Additionally, some ducted systems allow you to disable heating or cooling in unoccupied rooms, which can help save energy.

6

Use energy-saving LED lights

Image: Anton Belashov

LED lighting has been around for a while and can save up to 80% on lighting costs. LED bulbs consume less power and last longer, which means that users spend less money and time replacing them.

Another perk, LEDs generate very little heat compared to incandescent and halogen bulbs, which convert much of their energy into heat. This can reduce cooling costs, especially in warm climates.

7

Solar energy

The energy given to us by the sun can be harvested in solar panels that reduce the amount of energy we need to buy from the electricity company . Similarly, solar hot water systems can minimize gas usage, reducing reliance on gas-fired water heaters.

Solar panels and solar hot water systems used to be very expensive and had to be replaced much more often but, their costs have dropped significantly in recent years, making them more accessible.

TV settings

Image: Jonas Leupe

Today's high-definition televisions use around 60% less energy than earlier models. However, some Internet-ready models consume extra power even when turned off due to a "quick start" feature that enables faster boot-up . You can disable that option in your television's settings .

While perusing through the settings, you can also see if your model has an automatic brightness control, which will adjust the picture brightness to the level of light in the room. This can make a big difference in energy consumption.

Efficient appliances

Image: Vlad Zaytsev

Most of today's new appliances use half the energy of those from a couple of decades ago. If you're thinking of buying a new one, look for products with the Energy Star label, as they typically use 10 to 40 percent less energy than other models.

If you are going to buy a new computer, keep in mind that laptops use significantly less energy than desktop versions.

10

Insulate your roof

Image: Erik Mclean

Temperature affects air in different ways: heat rises, while cool air sinks. This means that if a house's roof is not properly insulated, heat will escape in the winter, and the cold from outside will seep in through the roof.

An insulated ceiling can make a big difference to your energy bills . Effective ceiling insulation can save up to 20% on cooling and heating costs.

Arizona skips Daylight Saving Time

Image: Christoph von Gellhorn

This is partly true because most of the state doesn’t bother with Daylight Saving Time . They stopped changing the clocks back in 1967. The exception is the Navajo Nation, which stretches into Utah and New Mexico and keeps DST so all its communities stay on the same schedule. Now, as for the smaller Hopi reservation, inside the Navajo Nation, it sticks with Arizona time… Yes, quite confusing if you’re not a local.

Georgia isn’t really the Peach State

Image: Jessica Furtney

Georgia loves its peaches, sure, but the state’s top fruit money-maker is actually blueberries . In recent years, blueberries have brought in several times more cash for farmers than peaches. Meanwhile, California grows far more peaches than Georgia ever has. The nickname stuck from the old days when Georgia peaches were famous for their flavor, not their volume. So while the pride is real, the peaches aren’t quite the powerhouse people may think.

3

Nevada didn’t record the hottest US temperature

Image: tommao wang

You probably think of Nevada’s desert heat as unmatched, but the all-time record belongs to California’s Death Valley . In July 1913, it hit a mind-melting 134 degrees Fahrenheit, the hottest temperature not only in America but the hottest ever recorded on Earth!

4

Minnesota doesn’t have the most lakes

Image: Tom Conway

Minnesota proudly calls itself the "Land of 10,000 Lakes," but that’s selling itself short… The real number is closer to 12,000. However, Alaska wins this battle . The state has more than 3 million lakes over five acres in size. In fact, Alaska contains over 40 percent of the nation’s surface water. If you love fishing, kayaking, or just staring at a quiet stretch of water, the true lake capital of America is far up north.

Pineapples aren’t native to Hawaii

Image: Christian Joudrey

Pineapples are everywhere in Hawaiian imagery, but the plant actually comes from South America , mainly Paraguay and southern Brazil. Spanish explorers likely brought them to Hawaii in the 1500s after spreading them across the Pacific to places like the Philippines and Guam. Hawaii’s climate turned out to be perfect for growing them and by the 1900s, the islands were producing so many pineapples that the fruit became a symbol of Hawaii itself.

Maine isn’t the country’s easternmost point

Image: Chris Henry

If you’re a Geography geek, you’ll love this one. You might picture Maine’s rocky coast as the eastern tip of America, but the actual easternmost point is thousands of miles away, on Alaska’s Semisopochnoi Island in the Aleutians. How is that possible? Well, that’s because it crosses the 180th meridian, putting it in the Eastern Hemisphere. That means part of Alaska technically sits farther east than anywhere in Maine.

The biggest US earthquake didn’t happen in California

Image: Lala Miklós

California has suffered some big earthquakes in its history, but the most powerful earthquake in America struck Alaska in 1964 . It hit Prince William Sound with a magnitude of 9.2. It was so strong it shook the ground for four and a half minutes and triggered massive tsunamis. In today’s dollars, the damage would total more than $2 billion. Alaska sits on a collision zone of tectonic plates, making it one of the world’s most seismically active regions.

The Everglades isn’t America’s biggest swamp

Image: Joshua J. Cotten

A lot of people picture the Florida Everglades when they think of swamps, but technically, the Everglades isn’t a swamp at all. The real title of the largest swamp in the United States goes to Louisiana’s Atchafalaya Basin , which spans about 1.4 million acres. This swamp has a vast mix of cypress forests, bayous, and marshes, and it’s more than twice as productive as the Everglades when it comes to wildlife and plant life.

Big cities aren’t always capitals

Image: Mackenzie Cruz

It surprises people how often the biggest city isn’t the state capital . New York City? Not the capital… Albany is. Chicago? Nope, that honor goes to Springfield. Pennsylvania’s capital isn’t Philly or Pittsburgh, it’s Harrisburg. Even California’s capital isn’t L.A. or San Francisco, it’s actually Sacramento. Out of fifty states, only seventeen have their most populous city as the capital.

10

Alaska isn’t divided into counties

Image: Rod Long

Alaska likes to do things its own way. Instead of counties, it’s split into boroughs , and a massive area known as the Unorganized Borough has no local government at all. People out there don’t pay property taxes, but that freedom comes with challenges, limited services, fewer job options, and tough living conditions.

Today, there are over 845,000 Portuguese speakers in the United States, making it the 12th most spoken language after English.

The Portuguese-speaking community is composed of immigrants from both Portugal and Brazil. Since the 1960s, many Portuguese immigrants have settled along the coast of Massachusetts, where they could continue their traditional fishing activities. Besides Massachusetts, Portuguese is most commonly spoken in Connecticut, Rhode Island, and Utah.

There are currently almost 950,000 Russian speakers in the United States. Did you know that Russian is one of the two official languages aboard the International Space Station? NASA astronauts typically take Russian language courses to communicate with their Russian counterparts.

Another well-known Russian-speaking community is in New York's Brighton Beach neighborhood, often referred to as "Little Odessa." Cultural events, festivals, and markets featuring traditional Russian foods, music, and crafts are common sights here. Los Angeles is another city where Russian is regularly used.

9. Korean

Image: 昆 阿

Over the past few decades, the number of Korean speakers in the United States has grown significantly, with nearly 1,100,000 people now speaking Korean .

Los Angeles is home to the largest Koreatown in the country, and many residents in other major cities speak Korean at home, helping to maintain and promote the heritage of this Asian culture in the United States.

8. Arabic

Image: Rawan Yasser

With more than 1.2 million speakers, Arabic is the eighth most spoken language in our country.

Arabic is spoken in immigrant communities from countries such as Egypt, Lebanon, Syria, Iraq, and Yemen. These communities are most prominent in states like California, New York, and Michigan, where Arabic is commonly heard in homes and community centers.

7. German

Image: FotosFuerBlogger

German is widely spoken in states with high populations of German ancestry, such as Pennsylvania, Wisconsin, and Texas. When including Yiddish, Pennsylvania Dutch, and other West Germanic languages, there are over 1,450,000 German speakers in the United States.

Cities like Fredericksburg and New Braunfels, Texas, were founded by German immigrants and continue to celebrate their heritage with festivals such as Oktoberfest. In Pennsylvania, a large number of Pennsylvania Dutch speakers—predominantly among the Amish and Mennonite communities—speak this German dialect, which is not, as one might expect, Dutch.

6. Vietnamese

Image: Huynh Van

The number of Vietnamese speakers in the United States is similar to that of the previous language on this list, with more than 1.5 million people speaking the language of this Southeast Asian country.

In recent decades, the number of Vietnamese immigrants has been increasing exponentially. Most have settled in California, followed by Texas, Florida, Washington, and Georgia.

Despite being the fifth most spoken language in the United States, Tagalog is often overlooked. For those who have never heard of it, Tagalog is one of the official languages of the Philippines.

A significant number of Filipino immigrants have settled in the United States since the early 19th century. According to the U.S. Census Bureau, there are currently more than 1.7 million Tagalog speakers . Thirty-eight percent of Filipinos in the United States live in California, with relatively large concentrations also in Hawaii and Texas.

4. French

Image: Erik Mclean

If we include Patois, Cajun, Haitian, and Louisiana Creole—a hybrid of French and various African languages—French is the fourth most widely spoken language in the United States.

The French influence, which dates back to the 17th century, is evident in a wide variety of American English words and phrases. Today, there are nearly 2.1 million French speakers in the country.

10

3. Chinese

Image: 五玄土 ORIENTO

The Chinese language, including its different variants such as Mandarin, Cantonese, and Hokkien, contributes significantly to the cultural diversity of the United States. Although the gap between the second and third most spoken languages in the country is considerable, the number of people who speak Chinese is still representative.

With approximately 3.5 million Chinese speakers across the country, the greatest influence of this culture can be found in states with the highest concentrations of Chinese immigrants, such as New York and California.

11

2. Spanish

Image: Leeloo The First

Spanish is the second most spoken language in the United States and one of the fastest-growing languages in the country. This is no surprise, as approximately 19% of the total population is of Hispanic origin.

According to the U.S. Census Bureau, more than 40 million people speak Spanish in addition to English in the United States. Hispanic communities are found throughout the nation, with the largest concentrations in California, Texas, Florida, and New York.

1. English

Image: Wilhelm Gunkel

Although it is not surprising that English is the most widely spoken language in the United States, it is still not recognized as an official language. However, more than half of the 50 states have passed laws granting it official language status.

English speakers make up a large percentage of the U.S. population, with approximately 78 percent speaking only English . American English is also incredibly rich, composed of dozens of regional dialects with distinct grammar, vocabulary, and pronunciation.
