Visualizing EV Sales Around the World

Published

on

It took five years to sell the first million electric cars. In 2018, it took only six months.

The Tesla Model 3 also passed a significant milestone in 2018, becoming the first electric vehicle (EV) to crack the 100,000 sales mark in a single year. The Nissan LEAF and BAIC EC-Series are both likely to surpass the 100,000 this year as well.

Although the electric vehicle market didn’t grow as fast as some experts initially projected, it appears that EV sales are finally hitting their stride around the world. Below are the countries where electric vehicles are a biggest part of the sales mix.

The EV Capital of the World

Norway, after amassing a fortune through oil and gas extraction, made the conscious decision to create incentives for its citizens to purchase electric vehicles. As a result, the country is the undisputed leader in EV adoption.

In 2018, a one-third of all passenger vehicles were fully electric, and that percentage is only expected to increase in the near future. The Norwegian government has even set the ambitious target of requiring all new cars to be zero-emission by 2025.

That enthusiasm for EVs is spilling over to other countries in the region, which are also seeing a high percentage of EV sales. However, the five countries in which EVs are the most popular – Norway, Iceland, Sweden, Netherlands, and Finland – only account for 0.5% of the world’s population. For EV adoption to make any real impact on global emissions, drivers in high-growth/high–population countries will need to opt for electric powered vehicles. (Of course power grids will need to get greener as well, but that’s another topic.)

China’s Supercharged Impact

One large economy that is embracing plug-in vehicles is China.

The country leads the world in electric vehicle sales, with over a million new vehicles hitting the roads in 2018. Last year, more EVs were sold in Shenzhen and Shanghai than any country in the world, with the exception of the United States.

China also leads the world in another important metric – charging stations. Not only does China have the highest volume of chargers, many of them allow drivers to charge up faster.

Accelerating from the Slow Lane

In the United States, electric vehicle sales are rising, but they still tend to be highly concentrated in specific areas. In around half of states, EVs account for fewer than 1% of vehicle sales. On the other hand, California is approaching the 10% mark, a significant milestone for the most populous state.

Nationally, EV sales increased throughout 2018, with December registering nearly double the sales volume of the same month in 2017. Part of this surge in sales is driven by the Tesla’s Model 3, which led the market in the last quarter of 2018.

U.S. Electric vehicle sales

North of the border, in Canada, the situation is similar. EV sales are increasing, but not fast enough to meet targets set by the government. Canada aimed to have half a million EVs on the road by 2018, but missed that target by around 400,000 vehicles.

The big question now is whether the recent surge in sales is a temporary trend driven by government subsidies and showmanship of Elon Musk, or whether EVs are now becoming a mainstream option for drivers around the world.

Animated: 140 Years of Global Surface Temperatures

For hundreds of years, Earth’s average surface temperature has been steadily increasing. And over the last decade, this global heating appears to have intensified.

Since 1880, the global average temperature has risen by an average of 0.08°C (0.14°F) every 10 years, according to the National Oceanic and Atmospheric Administration (NOAA).

But since 1981, warming has been occurring at more than twice that rate, by about 0.18°C (0.32°F) per decade.

This graphic by Pablo Alvarez shows 140 years of global surface temperatures, highlighting the 10 coldest and warmest years from 1880-2021 using data from NOAA.

Global Surface Temperatures Over Time

Over the last century and a half, there have been fluctuations in global surface temperatures, with some of the coolest years on record occurring in the late 19th century and early 20th century.

Average surface temperature since 1800

However, the last two decades have seen unprecedented warming, with the 10 warmest years on record all occurring within the last 20 years. Here’s a look at the 10 hottest years since 1800, and how they compared to the 20th century average:

The 10 Warmest Years

RankYearDeviation from 20th Century Avg. (°C)
#12016+0.99
#22020+0.97
#32019+0.94
#42015+0.93
#52017+0.9
#62018+0.82
#72014+0.74
#82010+0.72
#92013+0.67
#102005+0.66

As of this article’s publication, the warmest year on record was 2016, when temperatures were +0.99°C (1.78°F) above the 20th century average. After 2016, the second warmest year was 2020, when surface temperatures reached +0.97°C (1.75°F) higher than the previous century’s average.

What Factors Impact Earth’s Climate?

There are a number of natural factors that influence global surface temperatures, including phenomena such as:

  • Volcanic activity
  • Changes in the Earth’s orbit
  • Shifts in ocean currents

However, scientists believe that our current rate of warming has been undoubtedly caused by human influence, especially because of our carbon and other greenhouse gas (GHG) emissions.

According to the most recent report by the Intergovernmental Panel on Climate Change (IPCC), “observed increases in well-mixed greenhouse gas (GHG) concentrations since around 1750 are unequivocally caused by human activities.”

In other words, while Earth’s surface temperature naturally fluctuates over the years, our actions have undoubtedly contributed to recent changes in Earth’s climate.

What Are The Consequences?

We’re already seeing the impact of this warming, as the world struggles with extreme climate events like droughts, heatwaves, floods, and an influx of wildfires in places like Europe, the United States, and Australia.

These extreme weather patterns could become the new normal if left unchecked, which is why companies and policymakers around the world are embarking on different solutions—from targeting net zero goals to implementing technological innovations that could reduce emissions.

The U.S. Utilities Decarbonization Index

With the Biden administration targeting a zero-emissions power sector for the U.S. by 2035, how are the nation’s largest electric power providers faring in terms of decarbonization? 

Together, Visual Capitalist and our sponsor National Public Utilities Council have developed the Annual Utility Decarbonization Index. The index quantifies and compares the status of decarbonization among the 30 largest investor-owned utilities in the United States.

Decarbonization is quantified by scoring companies on six emissions-related metrics based on publicly available data from 2020 (the latest available).

Why the 30 Largest IOUs?

Why does the Decarbonization Index specifically look at the 30 largest IOUs by electricity generation? 

Well, these 30 utilities collectively generated around 2.3 billion megawatt hours (MWh) of electricity (including purchased power), making up over half of U.S. net electricity generation in 2020. Moreover, they also served over 90 million customers, accounting for roughly 56% of all electric customers in the country.

30 largest utilities in the U.S.

Therefore, it’s safe to say that the 30 largest IOUs have an important role in decarbonizing both the power sector and the U.S. economy. Since the residential, commercial, industrial, and agricultural sectors all use electricity, the decarbonization of utilities—the providers of electric power—can enable emissions reduction throughout the economy.

Decarbonization Index Methodology

For each of the six metrics used in the Decarbonization Index, utilities are scored on a scale of 1 (lowest) to 5 (highest), indicating whether they are trailing or leading, respectively. Scores for each metric are based on the range of figures for each metric divided into five equal buckets that the utilities fall into. 

For simplicity, let’s suppose that the lowest reported total emissions figure is zero metric tons of carbon dioxide (CO2) and the highest is 100 metric tons. In that case, companies that emit fewer than 20 metric tons of CO2 will receive the highest score of 5. Those that emit between 20 and 40 metric tons of CO2 will receive a 4, and so on.

A utility’s overall decarbonization score is an average of their scores across the six metrics, summarized below:

  1. Fuel Mix:
    The share of low-carbon sources (renewables, nuclear, and fuel cells) in the utility’s owned net electricity generation. We’ve assumed that the share of low-carbon sources can range from 0% to 100%, and scores are assigned based on that range.
  2. CO2 Emissions Intensity:
    The amount of CO2 emitted per megawatt-hour of owned and purchased electricity generation.
  3. Total CO2 Emissions:
    The sum of absolute CO2 emissions from owned and purchased electricity generation. While this overlooks the differing sizes of utilities, the rationale is that smaller unconsolidated utilities may find it easier to decarbonize than larger peers.
  4. CO2 Emissions per Capita:
    The amount of CO2 emitted from owned and purchased electricity generation per retail customer served in 2020.
  5. Decarbonization Goals:
    An evaluation of the utility’s interim greenhouse gas (GHG) emissions reduction goals and net-zero targets. The baseline for this is 50% GHG emissions reduction by 2030 and net-zero emissions by 2050 (utilities with baseline targets get a score of 2.5/5).
  6. Low-Carbon Investment:
    The share of planned capital expenditure (CAPEX) for electricity generation that is allocated to low-carbon sources. We’ve assumed that the share of CAPEX for low-carbon sources can range from 0% to 100%, and scores are assigned based on that range.

The data for these metrics comes from various sources including company sustainability reports, quantitative reporting templates from the Edison Electric Institute, and the Climate Disclosure Project’s Climate Change Questionnaire filings.

The Annual Utility Decarbonization Index 2022

Before looking at numbers, it’s important to note that the Decarbonization Index is relative and compares the 30 largest IOUs to each other. Therefore, a score of 5 does not indicate full decarbonization or net-zero emissions. Instead, it suggests that the utility is doing particularly well relative to its peers. 

With that in mind, here’s a look at the Annual Utility Decarbonization Index 2022:

#30Vistra Corp.2.0

A small number of companies did not report data on certain metrics and have been excluded from scoring for those metrics (denoted as N/A). In such cases, the decarbonization score is an average of five metrics instead of six.

Public Service Enterprise Group (PSEG), headquartered in New Jersey, tops this year’s rankings thanks to its low-emissions profile and ambitious climate goals. The company is aiming to achieve net-zero emissions from operations by 2030—five years ahead of the Biden Administration’s target and faster than any other utility on the list.

Tied with PSEG is NextEra Energy Resources, the clean energy-focused subsidiary of NextEra Energy. The company is the world’s largest producer of solar and wind power and generated 97% of its net electricity from low-carbon sources in 2020.

In third place is California’s largest utility, the Pacific Gas and Electric Company (PG&E). PG&E had the lowest emissions per capita of the 30 largest IOUs at 0.5 metric tons of CO2 per retail customer in 2020. That figure is significantly lower than the average of 11.5 metric tons across the 30 IOUs. 

Rounding out the top five are Avangrid, a renewables-focused U.S. subsidiary of the Spanish Iberdrola Group, and Exelon, the nation’s largest utility by number of retail customers. Avangrid had one of the cleanest fuel mixes with 87% of its owned net electricity coming from low-carbon sources. Exelon is the nation’s largest provider of emissions-free electricity, generating around 157 million MWh or 86% of its owned net electricity from nuclear power.
