Mapped: Solar Power by Country in 2021
The world is adopting renewable energy at an unprecedented pace, and solar power is leading the way.
Despite a 4.5% fall in global energy demand in 2020, renewable energy technologies showed promising progress. While the growth in renewables was strong across the board, solar power led from the front with 127 gigawatts installed in 2020, its largest-ever annual capacity expansion.
The above infographic uses data from the International Renewable Energy Agency (IRENA) to map solar power capacity by country in 2021. This includes both solar photovoltaic (PV) and concentrated solar power capacity.
The Solar Power Leaderboard
From the Americas to Oceania, countries in virtually every continent (except Antarctica) added more solar to their mix last year. Here’s a snapshot of solar power capacity by country at the beginning of 2021:
|Country||Installed capacity, megawatts||Watts* per capita||% of world total|
|South Korea 🇰🇷||14,575||217||2.0%|
|United Kingdom 🇬🇧||13,563||200||1.9%|
|South Africa 🇿🇦||5,990||44||0.8%|
|United Arab Emirates 🇦🇪||2,539||185||0.4%|
|Czech Republic 🇨🇿||2,073||194||0.3%|
|El Salvador 🇸🇻||429||66||0.1%|
|Saudi Arabia 🇸🇦||409||12||0.1%|
|Dominican Republic 🇩🇴||370||34||0.1%|
|New Zealand 🇳🇿||142||29||0.02%|
|World total 🌎||713,970||83||100.0%|
*1 megawatt = 1,000,000 watts.
China is the undisputed leader in solar installations, with over 35% of global capacity. What’s more, the country is showing no signs of slowing down. It has the world’s largest wind and solar project in the pipeline, which could add another 400,000MW to its clean energy capacity.
Following China from afar is the U.S., which recently surpassed 100,000MW of solar power capacity after installing another 50,000MW in the first three months of 2021. Annual solar growth in the U.S. has averaged an impressive 42% over the last decade. Policies like the solar investment tax credit, which offers a 26% tax credit on residential and commercial solar systems, have helped propel the industry forward.
Although Australia hosts a fraction of China’s solar capacity, it tops the per capita rankings due to its relatively low population of 26 million people. The Australian continent receives the highest amount of solar radiation of any continent, and over 30% of Australian households now have rooftop solar PV systems.
China: The Solar Champion
In 2020, President Xi Jinping stated that China aims to be carbon neutral by 2060, and the country is taking steps to get there.
China is a leader in the solar industry, and it seems to have cracked the code for the entire solar supply chain. In 2019, Chinese firms produced 66% of the world’s polysilicon, the initial building block of silicon-based photovoltaic (PV) panels. Furthermore, more than three-quarters of solar cells came from China, along with 72% of the world’s PV panels.
With that said, it’s no surprise that 5 of the world’s 10 largest solar parks are in China, and it will likely continue to build more as it transitions to carbon neutrality.
What’s Driving the Rush for Solar Power?
The energy transition is a major factor in the rise of renewables, but solar’s growth is partly due to how cheap it has become over time. Solar energy costs have fallen exponentially over the last decade, and it’s now the cheapest source of new energy generation.
Since 2010, the cost of solar power has seen a 85% decrease, down from $0.28 to $0.04 per kWh. According to MIT researchers, economies of scale have been the single-largest factor in continuing the cost decline for the last decade. In other words, as the world installed and made more solar panels, production became cheaper and more efficient.
This year, solar costs are rising due to supply chain issues, but the rise is likely to be temporary as bottlenecks resolve.

A wave of electric semi trucks is expected to arrive over the next few years. View this infographic to learn more.
Every Electric Semi Truck in One Graphic
Electric semi trucks are coming, and they could help to decarbonize the shipping and logistics industry. However, range remains a major limitation.
This presents challenges for long-hauling, where the average diesel-powered semi can travel up to 2,000 miles before refueling. Compare this to the longest range electric model, the Tesla Semi, which promises up to 500 miles. A key word here is “promises”—the Semi is still in development, and nothing has been proven yet.
In this infographic, we’ve listed all of the upcoming electric semi trucks, complete with range and charge time estimates. Further in the article, we’ll explore the potential commercial use cases of this first generation of trucks.
The following table includes all of the models included in the above infographic.
|Company||Truck Name||Range||Charge Time||Expected Delivery|
|🇺🇸 Tesla||Semi||300-500 miles||TBD||2023|
|🇺🇸 Freightliner||eCascadia||250 miles||80% in as low as 1.5 hrs||2022|
|🇸🇪 Volvo||VNR Electric||275 miles||80% in as low as 1 hr||2022|
|🇺🇸 Kenworth||T680E||150 miles||100% in as low as 3.3 hrs||TBD|
|🇺🇸 Peterbilt||579EV||150 miles||100% in as low as 3.3 hrs||2022|
|🇨🇳 BYD||8TT||167 miles||100% in as low as 2.5 hrs||In operation|
|🇺🇸 Nikola||Tre BEV||350 miles||10% to 80% in as low as 2 hrs||2022|

With the exception of Tesla’s Semi, all of these trucks are currently in operation or expected to begin delivering this year. You may want to take this with a grain of salt, as the electric vehicle industry has become notorious for delays.
In terms of range, Tesla and Nikola are promising the highest figures (300+ miles), while the rest of the competition is targeting between 150 to 275 miles. It’s reasonable to assume that the Tesla and Nikola semis will be the most expensive.
Charge times are difficult to compare because of the variables involved. This includes the amount of charge and the type of charger used. Nikola, for example, claims it will take 2 hours to charge its Tre BEV from 10% to 80% when using a 240kW charger.
Charger technology is also improving quickly. Tesla is believed to be rolling out a 1 MW (1,000 kW) charger that could add 400 miles of range in just 30 minutes.
Use Cases of Electric Semi Trucks
Given their relatively lower ranges, electric semis are unlikely to be used for long hauls.
Instead, they’re expected to be deployed on regional and urban routes, where the total distance traveled between destinations is much lower. There are many reasons why electric semis are suited for these routes, as listed below:
- Smaller batteries can be installed, which keeps the cost of the truck lower
- Urban routes provide greater opportunities to use regenerative braking
- Quieter and cleaner operation in densely populated areas
An example of a regional route would be delivering containers from the Port of Los Angeles to the Los Angeles Transportation Center Intermodal Facility (LATC). The LATC is where containers are loaded onto trains, and is located roughly 28 miles away.
With a round trip totaling nearly 60 miles, an electric semi with a range of 200 miles could feasibly complete this route three times before needing a charge. The truck could be charged overnight, as well as during off hours in the middle of the day.
Hydrogen for Long Hauls?
We’ve covered the differences between battery and hydrogen fuel cell vehicles in the past, but this was from a passenger car perspective. The conclusion, in that case, was that battery electric has become the dominant technology. In terms of long-haul trucking, however, hydrogen may have an edge.
If we look at what will become mainstream, probably for smaller mobility it will be EVs, and fuel cells for larger mobility. That is the conclusion so far.
-Toshihiro Mibe, CEO, Honda
There are several reasons for why hydrogen could be beneficial for delivering heavy cargo over long distances. These are listed below:
- Refueling a hydrogen fuel cell takes less time than recharging a battery. Note, however, that charge times are still improving.
- A fuel cell configuration is typically lighter than an equivalent battery pack. Less drivetrain weight translates to a higher cargo capacity.
- Hydrogen-powered trucks could achieve a much higher range.
This last point hasn’t been proven yet, but we can reference Nikola, which is developing hydrogen-powered semi trucks. The company has two models in the works, which are the Tre FCEV with a range of 500 miles, and the Two FCEV with a range of 900 miles.
Keep in mind that these numbers are once again estimates and that Nikola has been accused of fraud in the past.
Who’s Using Electric Semi Trucks Today?
Although there are very few models available, electric semi trucks are indeed being used today.
In January 2020, Anheuser-Busch announced that it had received its 100th 8TT. The 8TT is produced by China’s BYD Motors and was one of the first electric semis to see real-world application. The brewing company uses its 8TTs to deliver products to retail destinations across California (e.g. grocery stores).
Another U.S. company using electric semis is Walmart. The retailer is trialing both the eCascadia from Freightliner and the Tre BEV from Nikola. The trucks are being used to pick up cargo from suppliers and then deliver it to regional consolidation centers.
Visualizing 10 Years of Global EV Sales by Country
This infographic charts the exponential growth of EV sales by country over the last decade.
10 Years of EV Sales by Country
In 2011, around 55,000 electric vehicles (EVs) were sold around the world. 10 years later in 2021, that figure had grown close to 7 million vehicles.
With many countries getting plugged into electrification, the global EV market has seen exponential growth over the last decade. Using data from the International Energy Agency (IEA), this infographic shows the explosion in global EV sales since 2011, highlighting the countries that have grown into the biggest EV markets.
The Early EV Days
From 2011 to 2015, global EV sales grew at an average annual rate of 89%, with roughly one-third of global sales occurring in the U.S. alone.
|Year||Total EV Sales||CAGR|
|Total sales / Avg growth||1,448,162||89.3%|
In 2014, the U.S. was the largest EV market followed by China, the Netherlands, Norway, and France. But things changed in 2015, when China’s EV sales grew by 238% relative to 2014, propelling it to the top spot.
China’s growth had been years in the making, with the government offering generous subsidies for electrified cars, in addition to incentives and policies that encouraged production. In 2016, Chinese consumers bought more EVs than the rest of the world combined—and the country hasn’t looked back, accounting for over half of global sales in 2021.
EV Sales by Country in 2021
After remaining fairly flat in 2019, global EV sales grew by 38% in 2020, and then more than doubled in 2021. China was the driver of the growth—the country sold more EVs in 2021 than the rest of the world combined in 2020.
|Country||2021 EV Sales||% of Total|
|South Korea 🇰🇷||119,402||1.8%|
|Rest of Europe 🇪🇺||469,930||6.9%|
|Rest of the World 🌍||313,129||4.6%|
China has nearly 300 EV models available for purchase, more than any other country, and it’s also home to four of the world’s 10 largest battery manufacturers. Moreover, the median price of electric cars in China is just 10% more than conventional cars, compared to 45-50% on average in other major markets.
Germany, Europe’s biggest auto market, sold nearly 700,000 EVs in 2021, up 72% from 2020. The country hosts some of the biggest EV factories in Europe, with Tesla, Volkswagen, and Chinese battery giant CATL either planning or operating ‘gigafactories’ there. Overall, sales in Europe increased by 65% in 2021, as evidenced by the seven European countries in the above list.
The U.S. also made a comeback after a two-year drop, with EV sales more than doubling in 2021. The growth was supported by a 24% increase in EV model availability, and also by an increase in production of Tesla models, which accounted for half of U.S. EV sales.
Tesla’s Dominance in the U.S.
Tesla is the world’s most renowned electric car company and its dominance in the U.S. is unmatched.
Between 2011 and 2019, Tesla accounted for 40% of all EVs sold in the United States. Furthermore, Tesla cars have been the top-selling EV models in the U.S. in every year since 2015.
|EV Model||2021 Sales||% of 2021 U.S. EV Sales|
|Tesla Model Y*||185,994||29.5%|
|Tesla Model 3*||147,460||23.4%|
|Ford Mustang Mach-E||27,140||4.3%|
|Chevy Bolt EV/EUV||24,828||3.9%|
|Tesla Model S*||15,545||2.5%|
|Tesla Model X*||7,985||1.3%|
Share of total sales calculated using total U.S. EV sales of 631,152 units, based on data from the IEA.
Tesla accounted for over 50% of EV sales in the U.S. in 2021 with the Model Y—launched in 2019—taking the top spot. Furthermore, the Model Y remained the bestselling EV in the first quarter of 2022, with Tesla taking up a massive 75% of the EV market share.
Despite Tesla’s popularity, it could face a challenge as other automakers roll out new models and expand EV production. For example, General Motors aims to make 20 EV models available by 2025, and Ford expects to produce at least 2 million EVs annually by 2026. This increase in competition from incumbents and new entrants could eat away at Tesla’s market share in the coming years.
