Have you ever wondered about how electricity actually makes it to your household outlet?
It’s actually quite miraculous: a complex system of substations, transformers and wires allow electricity to be instantly accessed at your convenience, even though it is generated hundreds of miles away.
The following infographic shows how the power grid works – and it helps explain how electricity gets from the power plant to your household socket:
The power grid has four important parts:
Generation: Electricity is created by burning fossil fuels, nuclear reactions, or collecting wind, solar, or water energy.
Transmission: Electricity immediately goes to substations, where it is converted to a higher voltage via step-up transformers. This allows the electricity to travel long distances more efficiently.
Distribution: Poles take electricity to where it needs to go. It is converted to a low voltage through step-down transformers, so that it can be used by houses or businesses.
End Use: Once distributed, energy is used to keep food cold, rooms lit, and computers charged.
Power Grid Innovations
The future of grids is exciting, and these are some of the most important innovations that will affect how power is managed and distributed to cities:
Microgrids: These are tiny, self-sufficient grids that can be “detached” from the larger grid. Microgrids will help to mitigate grid disturbances, and will make power grids more resilient as a whole.
Energy Storage: As society becomes better at solving the energy problem with better batteries and other new ways of approaching energy storage, our grids will be better able to manage excess energy supply and demand.
Smart Meters: Smart meters allow two-way communication between consumers and utility companies. Such meters allow utility companies to more efficiently match energy generation and consumption. They also help to alert utility companies when power is out, so that any issues can be resolved faster.
The Evolution of Hydrogen: From the Big Bang to Fuel Cells
Hydrogen and fuel cell technology harnesses the power of the universe to bring clean energy on Earth. Here is its potential.
It all started with a bang…the big bang!
The explosive power of hydrogen fueled a chain reaction that led to the world we have today.
Now this power is being deployed on Earth to supply the energy needs of tomorrow.
Visualizing the Power of Hydrogen
Today’s infographic comes to us from the Canadian Hydrogen and Fuel Cell Association, and it outlines how hydrogen and fuel cell technology is harnessing the power of the universe to potentially fuel an energy revolution.
What is Hydrogen, and How’s it Used?
With one proton and one electron, hydrogen sits at the very beginning of the periodic table.
Despite hydrogen being the most common molecule in the universe, it is rarely found in its elemental state here on Earth. In fact, almost all hydrogen on the planet is bonded to other elements and can only be released via chemical processes such as steam reforming or electrolysis.
There are five ways hydrogen is being used today:
- Building heat and power
- Energy storage and power generation
- Industry energy
- Industry feedstock
However, what really unleashes the power of hydrogen is fuel cell technology. A fuel cell converts the chemical power of hydrogen into electrical power.
Hydrogen Unleashed: The Fuel Cell
In the early 1960’s, NASA first deployed fuel cells to power the electrical components of the Gemini and Apollo space capsules. Since then, this technology has been deployed in everything from the vehicle you drive, the train you take, and how your favorite products are delivered to your doorstep.
Nations around the world are committing to build hydrogen fueling stations to meet the growth in adoption of fuel cell technology for transportation.
Hydrogen: A Green Energy Solution
Hydrogen fuel and fuel cell technology delivers green solutions in seven ways.
- Decarbonizing industrial energy use
- Acting as a buffer to increase energy system resilience
- Enabling large-scale renewable energy integration and power generation
- Decarbonizing transportation
- Decarbonizing building heat and power
- Distribution energy across sectors and regions
- Providing clean feedstock for industry
According to a recent report by McKinsey, hydrogen and fuel cell technology has the potential to remove six gigatons of carbon dioxide emissions and employ more than 30 million people by 2050, all while creating a $2.5-trillion market.
This is technology that can be deployed today, with the potential to transform how we live and power our economies in a sustainable way.
Map: The Countries With the Most Oil Reserves
See the countries with the most oil reserves on this map, which resizes each country based on how many barrels of oil are contained in its borders.
Map: The Countries With the Most Oil Reserves
There’s little doubt that renewable energy sources will play a strategic role in powering the global economy of the future.
But for now, crude oil is still the undisputed heavyweight champion of the energy world.
In 2018, we consumed more oil than any prior year in history – about 99.3 million barrels per day on a global basis. This number is projected to rise again in 2019 to 100.8 million barrels per day.
The Most Oil Reserves by Country
Given that oil will continue to be dominant in the energy mix for the short and medium term, which countries hold the most oil reserves?
Today’s map comes from HowMuch.net and it uses data from the CIA World Factbook to resize countries based on the amount of oil reserves they hold.
Here’s the data for the top 15 countries below:
|Rank||Country||Oil Reserves (Barrels)|
|#1||🇻🇪 Venezuela||300.9 billion|
|#2||🇸🇦 Saudi Arabia||266.5 billion|
|#3||🇨🇦 Canada||169.7 billion|
|#4||🇮🇷 Iran||158.4 billion|
|#5||🇮🇶 Iraq||142.5 billion|
|#6||🇰🇼 Kuwait||101.5 billion|
|#7||🇦🇪 United Arab Emirates||97.8 billion|
|#8||🇷🇺 Russia||80.0 billion|
|#9||🇱🇾 Libya||48.4 billion|
|#10||🇳🇬 Nigeria||37.1 billion|
|#11||🇺🇸 United States||36.5 billion|
|#12||🇰🇿 Kazakhstan||30.0 billion|
|#13||🇨🇳 China||25.6 billion|
|#14||🇶🇦 Qatar||25.2 billion|
|#15||🇧🇷 Brazil||12.7 billion|
Venezuela tops the list with 300.9 billion barrels of oil in reserve – but even this vast wealth in natural resources has not been enough to save the country from its recent economic and humanitarian crisis.
Saudi Arabia, a country known for its oil dominance, takes the #2 spot with 266.5 billion barrels of oil. Meanwhile, Canada and the U.S. are found at the #3 (169.7 billion bbls) and the #11 (36.5 billion bbls) spots respectively.
The Cost of Production
While having an endowment of billions of barrels of oil within your borders can be a strategic gift from mother nature, it’s worth mentioning that reserves are just one factor in assessing the potential value of this crucial resource.
In Saudi Arabia, for example, the production cost of oil is roughly $3.00 per barrel, which makes black gold strategic to produce at almost any possible price.
Other countries are not so lucky:
|Country||Production cost (bbl)||Total cost (bbl)*|
|🇬🇧 United Kingdom||$17.36||$44.33|
|🇺🇸 U.S. shale||$5.85||$23.35|
|🇺🇸 U.S. non-shale||$5.15||$20.99|
|🇸🇦 Saudi Arabia||$3.00||$8.98|
Even if a country is blessed with some of the most oil reserves in the world, it may not be able to produce and sell that oil to maximize the potential benefit.
Countries like Canada and Venezuela are hindered by geology – in these places, the majority of oil is extra heavy crude or bitumen (oil sands), and these types of oil are simply more difficult and costly to extract.
In other places, obstacles are are self-imposed. In some countries, like Brazil and the U.S., there are higher taxes on oil production, which raises the total cost per barrel.
