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.

Mapped: The Greenest Countries in the World

From widening wealth disparity to the environmental ramifications of economic development—the growing focus on global sustainability is a clear sign of the times.

Research reveals that when a sustainable ethos is applied to policy and business, it typically bodes well for economies and people alike. By providing benchmarks for those decisions, indexes like Yale’s Environmental Performance Index (EPI) can be critical to measuring national sustainability efforts.

The above map interprets the EPI ranking of 180 economies across 32 environmental health indicators by narrowing in on the top 40 greenest countries.

Who’s the Greenest of them All?

Despite the decades-long trend of globalization, national environmental policies have proved to be widely divergent. The EPI report confirms that those policies—and their positive results—are highly correlated with national wealth.

This is evidenced in the global EPI distributions, seen below:

Regional grouping in the report include: Global West, Asia-Pacific, Eastern Europe, Former Soviet States, Greater Middle East, Latin America & Caribbean, Southern Asia, and Sub-Saharan Africa

Scandinavian countries, which tend to have a high GDP per capita, show strong and consistent results across EPI parameters. Denmark for instance—which ranks first overall—leads the world in slowing its growth in CO2 emissions. Meanwhile, neighbor Sweden leads in landfill and recycling treatment, while wastewater treatment is led by a handful of countries within and beyond Scandinavia including Denmark, Finland, the Netherlands, Singapore, and Sweden.

In North America, Canada claims top spot in the biodiversity and habitat category, while the U.S. ranks sixth in agricultural diversity globally. In Asia, Singapore leads the world in fishery health and sustainability.

Ultimately, it appears the world’s greenest countries tend to focus on all areas of sustainability, while laggard countries show more uneven performance across categories.

What Does “Green” Mean?

Each high-level performance indicator with the EPI, like “environmental health”, is broken into subsections. Nations are scored on each subsector on a scale up to 100. As a result, multiple countries can rank first in any given category.

By evaluating national sustainability on a scale that is unrelated to other nations, we get a clearer idea of comparative national progress, beyond a basic ranking.

For instance, 30 countries tie for first in marine protection, all with scores of 100. This shows that many economies are prioritizing this area of sustainability.

The EPI categories and subsectors are shown in the diagram below:

Greenest Countries in the World Supplemental EPI Index

Each section is weighted differently, and is reflected as a percentage within the index. For example, Ecosystem Vitality accounts for 60% of the EPI, Climate Change makes up 24% of a country’s score, and CO2 emission reduction is weighted at 13.2%.

The Cost of Being Green

Infrastructure costs are one reason why wealthier nations tend to fare better across sustainability measures. Everything from air pollution reduction and water treatment, to hazardous waste control and mitigation of public health crises are especially expensive—but have a huge potential impact on citizens.

This trend can be seen the scatterplot, which demonstrates the distribution of economies evaluated by the EPI:

Despite the strong correlation between GDP per capita and EPI score, developing countries do not have to abandon sustainability efforts. China for instance leads the world in the adoption of electric vehicle technology.

Post-Pandemic Outlook

Although some rankings can seem prosaic, indexes like the EPI provide a helpful benchmark for economies to compare efforts. It also allows governments to iterate and build upon environmental strategies and investments by highlighting what is and isn’t working.

CO2 emissions, for instance, are a major driver of climate change. Although the global economic stall has led to a temporary dip of CO2 emissions in early 2020 (a slower growth rate than the 11% expected rise), global emissions still continue.

However, the EPI shows that investments have impact. High-level sustainability efforts—political commitment, media coverage, regulations—can deliver results, even at the grassroots level.

How Much Solar Energy is Consumed Per Capita? (1965-2019)

This visualization highlights the growth in solar energy consumption per capita over 54 years. Which countries are leading the way?

How Much Solar Energy is Consumed Per Capita?

The long history of solar energy use dates as far back as 4,000 B.C.—when ancient civilizations would use solar architecture to design dwellings that would use more of the sun’s warmth in the winter, while reducing excess heat in the summer.

But despite its long history, we’ve only recently started to rely on solar energy as a renewable power source. This Our World in Data visualization pulls data from BP’s Statistical Review of World Energy to highlight how solar energy consumption per capita has grown in countries around the world over 54 years.

Solar Success: The Top Consumers Per Capita

Solar energy consumption is measured in kilowatt hours (kWh)—and as of the latest estimates, Australia leads the world in terms of highest solar energy consumption per capita at 1,764 kWh in 2019. A combination of factors help achieve this:

  • Optimal weather conditions
  • High gross domestic product (GDP) per capita
  • Tariffs incentivizing the shift to solar

In fact, government subsidies such as financial assistance with installation and feed-in tariffs help bring down the costs of residential solar systems to a mere AUD$1 (US$0.70) per watt.

#10🇪🇸 Spain7972.34%

Source: Our World in Data, BP Statistical Review of World Energy 2020
Note that some conversions have been made for primary energy consumption values from Gigajoules (GJ) to kWh.

Coming in second place, Japan has the highest share of solar (3.59%) compared to its total primary energy consumption per capita. After the Fukushima nuclear disaster in 2011, the nation made plans to double its renewable energy use by 2030.

Japan has achieved its present high rates of solar energy use through creative means, from repurposing abandoned golf courses to building floating “solar islands”.

Solar Laggards: The Bottom Consumers Per Capita

On the flip side, several countries that lag behind on solar use are heavily reliant on fossil fuels. These include several members of OPEC—Iraq, Iran, and Venezuela—and former member state Indonesia.

This reliance may also explain why, despite being located in regions that receive the most annual “sunshine hours” in the world, this significant solar potential is yet unrealized.

Note that some conversions have been made for primary energy consumption values from Gigajoules (GJ) to kWh.

Interestingly, Iceland is on this list for a different reason. Although the country still relies on renewable energy, it gets this from different sources than solar—a significant share comes from hydropower as well as geothermal power.

The Future of Solar

One thing the visualization above makes clear is that solar’s impact on the global energy mix has only just begun. As the costs associated with producing solar power continue to fall, we’re on a steady track to transform solar energy into a more significant means of generating power.

All in all, with the world’s projected energy mix from total renewables set to increase over 300% by 2040, solar energy is on a rising trend upwards.
