China’s Growth in Wind Power Stays Parabolic [Chart]
The Chart of the Week is a weekly feature in Visual Capitalist on Fridays.
It was only five years ago that China passed the United States in cumulative wind power capacity. Since then, the country hasn’t looked back and growth in wind power generation has continued exponentially.
The most recent numbers show that China now has more total wind capacity than the United States, India, and Spain combined. Even more impressive: for the year of 2014, China added 23,196 MW of new installed capacity, which is close to double that of the European Union’s growth in capacity over the same year (11,829 MW).
Why is China so bullish on wind? The answer is that because China is a quickly growing country, more power infrastructure has to be built each year to meet consumption growth. Meanwhile, for developed countries in North America and Europe, tinkering with the power grid happens on a smaller scale as adequate infrastructure already exists.
China’s power mix was not optimal to start with. In 2012, it was estimated that two-thirds of the country’s electricity was generated by coal. Coal will still be a big part of the mix moving forward, but the country is trying to diversify into nuclear as well as wind energy. That’s why wind is now the third most important source of electricity in the nation behind coal and hydro.
The growth in wind is not expected to stop soon. The Gansu Wind Farm Project is currently under construction and highlights China’s thirst for additional wind energy. When completed and operational, it is expected to become the world’s biggest collective windfarm.

The Carbon Footprint of Major Travel Methods
Going on a cruise ship and flying domestically are the most carbon-intensive travel methods.
The Carbon Footprint of Major Travel Methods

Did you know that transport accounts for nearly one-quarter of global energy-related carbon dioxide (CO₂) emissions?
This graphic illustrates the carbon footprints of major travel methods measured in grams of carbon dioxide equivalent (CO₂e) emitted per person to travel one kilometer. This includes both CO₂ and other greenhouse gases.
Data is sourced from Our World in Data, the UK Government’s Department for Energy Security and Net Zero, and The International Council on Clean Transportation, as of December 2022.
These figures should be interpreted as approximations, rather than exact numbers. There are many variables at play that determine the actual carbon footprint in any individual case, including vehicle type or model, occupancy, energy mix, and even weather.
Cruise Ships are the Most Carbon-Intensive Travel Method
According to these estimates, taking a cruise ship, flying domestically, and driving alone are some of the most carbon-intensive travel methods.
Cruise ships typically use heavy fuel oil, which is high in carbon content. The average cruise ship weighs between 70,000 to 180,000 metric tons, meaning they require large engines to get moving.
These massive vessels must also generate power for onboard amenities such as lighting, air conditioning, and entertainment systems.
Short-haul flights are also considered carbon-intensive due to the significant amount of fuel consumed during initial takeoff and climbing altitude, relative to a lower amount of cruising.
| Transportation method | CO₂ equivalent emissions per passenger km |
|---|---|
| Cruise Ship | 250 |
| Short-haul flight (i.e. within a U.S. state or European country) | 246 |
| Diesel car | 171 |
| Gas car | 170 |
| Medium-haul flight (i.e. international travel within Europe, or between U.S. states) | 151 |
| Long-haul flight (over 3,700 km, about the distance from LA to NY) | 147 |
| Motorbike | 113 |
| Bus (average) | 96 |
| Plug-in hybrid | 68 |
| Electric car | 47 |
| National rail | 35 |
| Tram | 28 |
| London Underground | 27 |
| Ferry (foot passenger) | 19 |
| Eurostar (International rail) | 4.5 |
Are EVs Greener?
Many experts agree that EVs produce a lower carbon footprint over time versus traditional internal combustion engine (ICE) vehicles.
However, the batteries in electric vehicles charge on the power that comes straight off the electrical grid—which in many places may be powered by fossil fuels. For that reason, the carbon footprint of an EV will depend largely on the blend of electricity sources used for charging.
There are also questions about how energy-intensive it is to build EVs compared to a comparable ICE vehicle.
