The Alternative Energy Sources of the Future

Despite the hype around the progress of renewable energy, many people don’t realize that solar and wind have only made a tiny dent in the energy mix thus far. The good news is that costs are coming down and many people are starting to adopt green technologies, but there is still a mountain to climb if we want to truly get off of fossil fuels on a large scale.

To accomplish this, we’re going to have to think outside the box to come up with new ways to tackle the energy challenge. Luckily, the folks at Futurism have put ten of the most promising alternative energy sources of the future in a handy infographic. Some of these may be long shots, but some may also play a crucial role in the energy mix of the future.

Space-based solar
Most solar energy doesn’t actually make it into the Earth’s atmosphere, so space-based solar power makes a lot of sense. The challenges are the cost in getting a satellite to orbit, as well as the conversion of electricity into microwaves that can be beamed down to the planet’s surface.

Human power
There’s over seven billion people walking around the Earth each day, so why not generate power from the movement of people? Many experts believe that we can harness this energy, and that we could use it to power our devices.

Tidal power
Five countries around the world are starting to operate viable wave power farm operations, but the potential is far higher: the U.S. coastline alone has a wave energy potential of about 252 billion KWh per year.

Hydrogen power
Hydrogen is a clean and potent source of energy, and best of all – it accounts for 74% of the mass of the entire universe. The only problem is that hydrogen atoms tend to only be found in combinations with oxygen, carbon, and nitrogen atoms. Removing this bond takes energy, which ends up being counter-productive. As a result, many people around the world are working on making these processes more economic.

Magma power
The center of the Earth is very hot, so why not try and get closer to it to tap into some geothermal heat? People in Iceland are already doing this with red-hot magma after accidentally striking a pocket of it during a 2008 drilling project.

Nuclear waste
Only 5% of uranium atoms are used in a traditional fission reaction. The rest end up in the pile of nuclear waste, which sits in storage for thousands of years. Researchers and companies are trying to tap into these leftovers for a viable and economic energy solution.

Embeddable solar power
What if every window could be easily turned into a solar panel? Solar window technology turns any window or sheet of glass into a photovoltaic solar cell that harvests the part of the light spectrum that eyes can’t see.

Algae power
Algae grows practically anywhere, and it turns out these tiny plants are a surprising source of energy-rich oils. Up to 9,000 gallons of biofuel could be “grown” per acre, making it one of many potential energy sources of the future.

Flying wind power
Winds are much more powerful and strong at higher elevations. If wind farms could be autonomous and flying, they could go to where the winds are strongest and deliver double the energy of similarly sized tower-mounted turbines.

Fusion power
Fusion has been the dream for some time – but scientists are making baby steps to achieving the power process that is harnessed in nature by our own sun. The ITER (International Thermonuclear Experimental Reactor) is currently being built in France, and it’s one of the most complex scientific and engineering projects in existence.

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.

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.

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.

Mapped: The World’s Largest State-Owned Oil Companies

State-owned oil companies control roughly three-quarters of global oil supply. See how these companies compare in this infographic.

Mapped: The World’s Largest State-Owned Oil Companies

Oil is one of the world’s most important natural resources, playing a critical role in everything from transportation fuels to cosmetics.

For this reason, many governments choose to nationalize their supply of oil. This gives them a greater degree of control over their oil reserves as well as access to additional revenue streams. In practice, nationalization often involves the creation of a national oil company to oversee the country’s energy operations.

What are the world’s largest and most influential state-owned oil companies?

Editor’s Note: This post and infographic are intended to provide a broad summary of the state-owned oil industry. Due to variations in reporting and available information, the companies named do not represent a comprehensive index.

State-Owned Oil Companies by Revenue

National oil companies are a major force in the global energy sector, controlling approximately three-quarters of the Earth’s oil reserves.

As a result, many have found their place on the Fortune Global 500 list, a ranking of the world’s 500 largest companies by revenue.

China is home to the two largest companies from this list, Sinopec Group and China National Petroleum Corporation (CNPC). Both are involved in upstream and downstream oil operations, where upstream refers to exploration and extraction, and downstream refers to refining and distribution.

It’s worth noting that many of these companies are listed on public stock markets—Sinopec, for example, trades on exchanges located in Shanghai, Hong Kong, New York, and London. Going public can be an effective strategy for these companies as it allows them to raise capital for new projects, while also ensuring their governments maintain control. In the case of Sinopec, 68% of shares are held by the Chinese government.

Saudi Aramco was the latest national oil company to follow this strategy, putting up 1.5% of its business in a 2019 initial public offering (IPO). At roughly $8.53 per share, Aramco’s IPO raised $25.6 billion, making it one of the world’s largest IPOs in history.

Geopolitical Tensions

Because state-owned oil companies are directly tied to their governments, they can sometimes get caught in the crosshairs of geopolitical conflicts.

The disputed presidency of Nicolás Maduro, for example, has resulted in the U.S. imposing sanctions against Venezuela’s government, central bank, and national oil company, Petróleos de Venezuela (PDVSA). The pressure of these sanctions is proving to be particularly damaging, with PDVSA’s daily production in decline since 2016.

State-Owned Oil Companies - Venezuela example

In a country for which oil comprises 95% of exports, Venezuela’s economic outlook is becoming increasingly dire. The final straw was drawn in August 2020 when the country’s last remaining oil rig suspended its operations.

Other national oil companies at the receiving end of American sanctions include Russia’s Rosneft and Iran’s National Iranian Oil Company (NIOC). Rosneft was sanctioned by the U.S. in 2020 for facilitating Venezuelan oil exports, while NIOC was targeted for providing financial support to Iran’s Islamic Revolutionary Guard Corps, an entity designated as a foreign terrorist organization.

Climate Pressures

Like the rest of the fossil fuel industry, state-owned oil companies are highly exposed to the effects of climate change. This suggests that as time passes, many governments will need to find a balance between economic growth and environmental protection.

Brazil has already found itself in this dilemma as the country’s president, Jair Bolsonaro, has drawn criticism for his dismissive stance on climate change. In June 2020, a group of European investment firms representing $2 trillion in assets threatened to divest from Brazil if it did not do more to protect the Amazon rainforest.

These types of ultimatums may be an effective solution for driving climate action forward. In December 2020, Brazil’s national oil company, Petrobras, pledged a 25% reduction in carbon emissions by 2030. When asked about commitments further into the future, however, the company’s CEO appeared to be less enthusiastic.

That’s like a fad, to make promises for 2050. It’s like a magical year. On this side of the Atlantic we have a different view of climate change.

— Roberto Castello Branco, CEO, Petrobras

With its 2030 pledge, Petrobras joins a growing collection of state-owned oil companies that have made public climate commitments. Another example is Malaysia’s Petronas, which in November 2020, announced its intention to achieve net-zero carbon emissions by 2050. Petronas is wholly owned by the Malaysian government and is the country’s only entry on the Fortune Global 500.

Challenges Lie Ahead

Between geopolitical conflicts, environmental concerns, and price fluctuations, state-owned oil companies are likely to face a much tougher environment in the decades to come.

For Petronas, achieving its 2050 climate commitments will require significant investment in cleaner forms of energy. The company has been involved in numerous solar energy projects across Asia and has stated its interests in hydrogen fuels.

Elsewhere, China’s national oil companies are dealing with a more near-term threat. In compliance with an executive order issued by the Trump Administration in November 2020, the New York Stock Exchange (NYSE) announced it would delist three of China’s state-run telecom companies. Analysts believe oil companies such as Sinopec could be delisted next, due to their ties with the Chinese military.
