The share of electricity generated by different energy sources has changed significantly in Europe over the last two decades.
The major story here is the decline in consumption of fossil fuels. More specifically, the combined share of petroleum products and solid fuels (meaning coal or shale oil) has fallen from 65.1% of total consumption in 1990 to 50.6% by 2013.
Renewables have steadily increased in consumption since the mid-2000s, and as a result the amount of electricity driven by renewables was 2.8x higher in 2013 (11.8%) than it was in 1990 (4.3%). The energy source that has seen the least fluctuations in usage is nuclear energy. Producing a peak of 14.5% of electricity in 2002, nuclear energy usage has recently dropped back to 13.6% in 2013.
Consumption of gas is also an interesting story. Natural gas has been used more prominently in recent years as it became regarded as more environmentally friendly than other fossil alternatives. However, as Europe has tried to reduce dependence on Russian gas, consumption has started to wane since 2010.
Here’s how specific countries look in terms of their electricity consumption per capita:
This creates some more granular stories that are worth delving into.
Estonia is the country that relies the most on solid fuels, with 86.6% of its energy needs met this fuel type. Interestingly, coal is not the solid fuel that is powering most of the country – that accolade goes to Estonia’s highly-developed and strategic shale oil resource. In this case, shale oil counts as a “solid fuel”, as it is essentially sedimentary rocks with oil trapped in them. Estonia actually has the two largest shale oil power plants in the world, and the industry employs 6,500 people in the country.
Malta and Cyprus rely heavily on petroleum products, which account for 98.3% and 92.4% of consumption respectively. This makes sense, as these small island nations do not have the populations or resources to warrant big infrastructure spending on things like nuclear power plants. They simply import what they need, which allows them flexibility.
France is the biggest user of nuclear power, with 74% of consumption coming from that source. Belgium, Hungary, and Slovakia have more than half of their power coming from nuclear.
Austria uses the most renewable energy with 80%. That said, the vast majority of this comes from hydro, where Austria uses its mountainous terrain to its advantage.

The Top 10 Biggest Companies in Brazil
What drives some of the world’s emerging economies? From natural resources to giant banks, here are the top 10 biggest companies in Brazil.
The Top 10 Biggest Companies in Brazil
In 2009, the at-the-time emerging economies of Brazil, Russia, India, and China held their first formal summits as members of BRIC (with South Africa joining in 2010).
Together, BRICS represents 26.7% of the world’s land surface and 41.5% of its population. By GDP ranking, they’re also some of the most powerful economies in the world.
But what drives their economies? We’re highlighting the top 10 biggest companies in each country, starting with Brazil.
What Are the Biggest Public Companies in Brazil?
Brazil isn’t just one of the largest and most diverse countries in the world, it is also an economic powerhouse.
With over 213 million people, Brazil is the sixth most populous country on Earth and the largest in Latin America. It’s also the wealthiest on the continent, with the world’s 12th-largest economy.
Once a colony focused on sugar and gold, Brazil rapidly industrialized in the 20th century. Today, it is a top 10 exporter of industrial steel, with the country’s economic strength coming chiefly from natural resources and financials.
Here are Brazil’s biggest public companies by market capitalization in October 2021:
|Top 10 Companies (October 2021)||Category||Market Cap (USD)|
|Vale||Metals and Mining||$73.03B|
|Petróleo Brasileiro||Oil and Gas||$69.84B|
|Banco Santander Brasil||Financial||$24.70B|
|Rede D’Or Sao Luiz||Hospital||$23.79B|
At the top of the ranking is Vale, a metals and mining giant that is the world’s largest producer of iron ore and nickel. Also the operator of infrastructure including hydroelectricity plants, railroads, and ports, It consistently ranks as the most valuable company in Latin America.
Vale and second-ranking company Petróleo Brasileiro, Brazil’s largest oil producer, were former state-owned corporations that became privatized in the 1990s.
Finance in Brazil’s Top 10 Biggest Companies
Other than former monopolies, the top 10 biggest companies in Brazil highlight the power of the banking sector.
Five of the 10 companies with a market cap above $20 billion are in the financial industry.
They include Itaú Unibanco, the largest bank in the Southern Hemisphere, and Banco Santander Brasil, the Brazilian subsidiary of Spanish finance corp.
Another well-known subsidiary is brewing company Ambev, which produces the majority of the country’s liquors and also bottles and distributes PepsiCo products in much of Latin America. Ambev is an important piece of Belgian drink juggernaut Anheuser-Busch InBev, which is one of the world’s largest 100 companies.
Noticeably missing from the top 10 list are companies in the agriculture sector, as Brazil is the world’s largest exporter of coffee, soybeans, beef, and ethanol. Many multinational corporations have Brazilian subsidiaries or partners for supply chain access, which has recently put a spotlight on Amazon deforestation.

Which Countries Have the Most Nuclear Weapons?
How big is the world’s nuclear arsenal? Here are the stockpiles of the nine countries with nuclear weapons.
Which Countries Have the Most Nuclear Weapons?
In theory, nuclear weapon stockpiles are closely held national secrets. The leading countries have rough estimates that aren’t regularly updated, newly nuclear countries keep their capabilities vague and unclear, and Israel has never officially confirmed a nuclear weapons program.
But thanks to limited disclosures, records, and leaks, we can visualize the full extent* of the world’s nuclear arsenal. This graphic uses estimated nuclear warhead inventories from the Federation of American Scientists as of August 2021.
Based on these estimates, there are just nine countries with nuclear weapons in the world.
Editor’s note: Exact numbers of nuclear warheads possessed by countries are closely guarded state secrets, with the FAS estimate being the closest, most-used, and most-trusted international approximation available.
Nuclear Weapons, by Country
The nuclear arms race has always centered around the U.S. and Russia.
After the end of World War II and well into the Cold War, the world’s two superpowers raced to build more nuclear weapons (and more capable nuclear weapons) than the other.
Even while international organizations lobbied for the end of nuclear proliferation, the world’s nuclear weapon stockpile grew to a peak of 70,300 total warheads in 1986.
As arms agreements and non-proliferation treaties started to gain greater momentum, the U.S. and Russia cut back on stockpiles while new countries with nuclear weapons started to pop up.
|Country||Total Warheads (2021)||% of Total|
|🇰🇵 North Korea||45||0.34%|
Despite reducing their stockpiles significantly since the end of the Cold War, Russia and the U.S. still own around 90% of all nuclear warheads in the world.
Far behind them are China and France, which started testing nuclear weapons in 1964 and 1960 respectively. The UK has the fifth-most nuclear weapons today, though it was the third country in the world to develop them after the U.S. and Russia in 1952.
The countries with fewer than 200 nuclear weapons are regional rivals India and Pakistan, which first tested nuclear weapons in the 1970s, and North Korea, which began to operate uranium fabrication plants and conduct explosive tests in the 1980s.
Israel is also estimated to have fewer than 200 nuclear weapons, and reports have its weapons program dating back to the 1960s. However, the country has never confirmed or announced its nuclear capabilities.
Countries With Nuclear Weapons, by Warhead Status
Though the world has 13,132 nuclear weapons, that doesn’t mean they’re all ready to fire.
Weapons (or “warheads”) are delivered by missile, and countries don’t keep all of their nuclear warheads primed for use. The estimation of nuclear stockpiles also clarifies whether warheads are considered deployed, reserved, or retired:
- Deployed warheads are deployed on intercontinental missiles, at heavy bomber bases, and on bases with operational short-range delivery systems.
- Reserve warheads are in storage and not deployed on launchers.
- Retired warheads are still intact but in queue for dismantlement.
|Country||Deployed Warheads||Reserve Warheads||Retired Warheads|
|🇰🇵 North Korea||0||45||0|
Only four countries have officially deployed warheads, while the majority of the world’s nuclear stockpile is in reserve. This is partially due to estimates ranging from relatively transparent in the case of the U.S. to opaque and uncertain for countries like China and North Korea.
But some countries are expected to further bolster their stockpiles. The UK government announced it would increase its stockpile to no more than 260 warheads, and U.S. intelligence expects China, India, and Pakistan to increase their stockpiles.
Though the world’s nuclear stockpile will likely continue dwindling on account of U.S. and Russia retirements, the 2021 landscape of countries with nuclear weapons shows that proliferation is still underway.
