The Best Online ESL Course

We recently compiled a list of the 20 Best Online ESL Courses and Programs and in this article we will talk about the best online ESL course.

What is ESL and Why is it Important?

ESL or English as a second language refers to programs, courses, or certifications designed specifically for non-native speakers willing to learn English. English is one of the fastest-growing languages. According to an article by Tomedes, the number of English speakers in the world increased from 1.05 billion in 2011 to 1.30 billion in 2021. A growth rate of 23.31% was observed in the number of English speakers in just a decade. English has been the fastest-growing language over the past 100 years as well. Based on the historical evidence, the number of English speakers can be expected to further increase over time.

Countries with English as an official language in the world are logically inclined towards employees who can speak and understand English. For this reason, the demand for ESL courses and programs is also increasing. According to an article by Eurostat, in 2021, almost 88% of all students in the European Union were learning English as a second language. The numbers were as high as 99% in many countries including Spain and Malta for learning English as a foreign language. 97% of the students were enrolled in general programs for learning English in the EU and 79% were enrolled in vocational programs in 2021. Therefore, ESL courses can help a person in various ways from landing a better job, moving to a new country, or communicating with people in a country you are traveling to.

Online Language Learning

Online language learning platforms provide an easy and accessible way to enhance language skills from the comfort of your home. According to a report by Spherical Insights, the global online language-learning market was valued at $15.24 Billion in 2023. The market is expected to grow at a compound annual growth rate (CAGR) of 13.68% from 2023 to 2033 and reach $54.95 Billion by the end of the projected period. The global online language learning market is expected to grow significantly due to trends including tourism, increased job opportunities, and the focus on bilingual education. Globalization is also expected to fuel the growth of the market. Europe is predicted to be the fastest-growing region in the global online language-learning market throughout the forecasted period.

Duolingo Inc (NASDAQ:DUOL) is one of the most prominent online language learning industry names. It offers a mobile app and a website that allows users to learn a new language free of cost. On December 4, 2023, the company published a report noting the trends in language learning based on learner behaviors. English was the most popular language among learners in 122 countries marking an increase of three countries compared to 119 in 2022. 40% of the users from India and 54% from China mentioned that their motivation for learning English is for education. Duolingo Inc (NASDAQ:DUOL) has incorporated several immersive features into its design to create a more engaging experience including experience points and in-app currency.

The popularity of English has led to Duolingo Inc (NASDAQ:DUOL) offering almost twenty English language courses for ESL students. The rationale for having more than one English language course is to cater to the unique needs of ESL students based on their country of origin. Here are some comments from the company’s earnings call:

“We have an English course for Chinese speakers and that’s a different course than the English course for Spanish speakers, etc. So we have about 20 English courses. And, if you look three years ago or so, they got you to different levels of proficiency, each one of these courses, and none of them got you to a very high proficiency. What we have done over the last couple of years, and this is one of the major achievements of this company, is we’ve made it so that our English courses, in particular 18 of our 20 English courses now, get you pretty high proficiency. So that’s the first thing we needed to do is get people to more advanced levels because English, in particular, English learners usually are at more advanced levels than other languages.”

Apart from online websites and mobile apps, online courses from universities and professionals are also available. These courses use proper techniques for teaching English as a second language and often offer certification on completion. People seeking to learn English for formal endeavors and career progression are likely to enroll in online ESL courses. With that, let’s take a look at the best online ESL course or program available.

Our Methodology 

To make our list of the 20 best online ESL courses and programs, we initially sifted through ten sources that listed or ranked them and compiled an initial list. We then looked up the number of reviews and average ratings for each of these programs. For the programs available on more than one source, we aggregated the number of reviews and took averages of ratings across platforms. The average ratings have been used as the secondary metric and the number of reviews have been used as a primary metric. For our list, we have only considered programs that had an average rating of more than 4.0 and the number of reviews greater than 100. For the programs with the same number of reviews, we have used the ratings as a tie-breaker.

At Insider Monkey we are obsessed with the stocks that hedge funds pile into. The reason is simple: our research has shown that we can outperform the market by imitating the top stock picks of the best hedge funds. Our quarterly newsletter’s strategy selects 14 small-cap and large-cap stocks every quarter and has returned 275% since May 2014, beating its benchmark by 150 percentage points (see more details here).

AI, Tariffs, Nuclear Power: One Undervalued Stock Connects ALL the Dots (Before It Explodes!)

Artificial intelligence is the greatest investment opportunity of our lifetime. The time to invest in groundbreaking AI is now, and this stock is a steal!

AI is eating the world—and the machines behind it are ravenous.

Each ChatGPT query, each model update, each robotic breakthrough consumes massive amounts of energy. In fact, AI is already pushing global power grids to the brink.

Wall Street is pouring hundreds of billions into artificial intelligence—training smarter chatbots, automating industries, and building the digital future. But there’s one urgent question few are asking:

Where will all of that energy come from?

AI is the most electricity-hungry technology ever invented. Each data center powering large language models like ChatGPT consumes as much energy as a small city. And it’s about to get worse.

Even Sam Altman, the founder of OpenAI, issued a stark warning:

“The future of AI depends on an energy breakthrough.”

Elon Musk was even more blunt:

“AI will run out of electricity by next year.”

As the world chases faster, smarter machines, a hidden crisis is emerging behind the scenes. Power grids are strained. Electricity prices are rising. Utilities are scrambling to expand capacity.

And that’s where the real opportunity lies…

One little-known company—almost entirely overlooked by most AI investors—could be the ultimate backdoor play. It’s not a chipmaker. It’s not a cloud platform. But it might be the most important AI stock in the US owns critical energy infrastructure assets positioned to feed the coming AI energy spike.

As demand from AI data centers explodes, this company is gearing up to profit from the most valuable commodity in the digital age: electricity.

The “Toll Booth” Operator of the AI Energy Boom

  • It owns critical nuclear energy infrastructure assets, positioning it at the heart of America’s next-generation power strategy.
  • It’s one of the only global companies capable of executing large-scale, complex EPC (engineering, procurement, and construction) projects across oil, gas, renewable fuels, and industrial infrastructure.
  • It plays a pivotal role in U.S. LNG exportation—a sector about to explode under President Trump’s renewed “America First” energy doctrine.

Trump has made it clear: Europe and U.S. allies must buy American LNG.

And our company sits in the toll booth—collecting fees on every drop exported.

But that’s not all…

As Trump’s proposed tariffs push American manufacturers to bring their operations back home, this company will be first in line to rebuild, retrofit, and reengineer those facilities.

AI. Energy. Tariffs. Onshoring. This One Company Ties It All Together.

While the world is distracted by flashy AI tickers, a few smart investors are quietly scooping up shares of the one company powering it all from behind the scenes.

AI needs energy. Energy needs infrastructure.

And infrastructure needs a builder with experience, scale, and execution.

This company has its finger in every pie—and Wall Street is just starting to notice.

Wall Street is noticing this company also because it is quietly riding all of these tailwinds—without the sky-high valuation.

While most energy and utility firms are buried under mountains of debt and coughing up hefty interest payments just to appease bondholders…

This company is completely debt-free.

In fact, it’s sitting on a war chest of cash—equal to nearly one-third of its entire market cap.

It also owns a huge equity stake in another red-hot AI play, giving investors indirect exposure to multiple AI growth engines without paying a premium.

And here’s what the smart money has started whispering…

The Hedge Fund Secret That’s Starting to Leak Out

This stock is so off-the-radar, so absurdly undervalued, that some of the most secretive hedge fund managers in the world have begun pitching it at closed-door investment summits.

They’re sharing it quietly, away from the cameras, to rooms full of ultra-wealthy clients.

Why? Because excluding cash and investments, this company is trading at less than 7 times earnings.

And that’s for a business tied to:

  • The AI infrastructure supercycle
  • The onshoring boom driven by Trump-era tariffs
  • A surge in U.S. LNG exports
  • And a unique footprint in nuclear energy—the future of clean, reliable power

You simply won’t find another AI and energy stock this cheap… with this much upside.

This isn’t a hype stock. It’s not riding on hope.

It’s delivering real cash flows, owns critical infrastructure, and holds stakes in other major growth stories.

This is your chance to get in before the rockets take off!

Disruption is the New Name of the Game: Let’s face it, complacency breeds stagnation.

AI is the ultimate disruptor, and it’s shaking the foundations of traditional industries.

The companies that embrace AI will thrive, while the dinosaurs clinging to outdated methods will be left in the dust.

As an investor, you want to be on the side of the winners, and AI is the winning ticket.

Should I put my money in Artificial Intelligence?

Here to answer that for us… and give away his No. 1 free AI recommendation… is 50-year Wall Street titan, Marc Chaikin.

Marc’s been a trader, stockbroker, and analyst. He was the head of the options department at a major brokerage firm and is a sought-after expert for CNBC, Fox Business, Barron’s, and Yahoo! Finance…

But what Marc’s most known for is his award-winning stock-rating system. Which determines whether a stock could shoot sky-high in the next three to six months… or come crashing down.

That’s why Marc’s work appears in every Bloomberg and Reuters terminal on the planet…

And is still used by hundreds of banks, hedge funds, and brokerages to track the billions of dollars flowing in and out of stocks each day.

He’s used this system to survive nine bear markets… create three new indices for the Nasdaq… and even predict the brutal bear market of 2022, 90 days in advance.
