General Knowledge
True or False? EDF only operates and supplies energy in France.
False
True or False? Energy customer service teams are trained to identify and give extra support to "vulnerable customers"—such as the elderly, chronically ill, or those using critical medical equipment at home.
True
Context: In the energy sector, safeguarding vulnerable households is a major priority. Teams use registers (like the Priority Services Register in the UK) to ensure these households get extra care during power outages or billing issues.
True or False? Hydropower (using flowing water to turn turbines and create electricity) is a technology EDF uses, making it the largest producer of renewable energy in Europe.
True
Context: People often forget about water! EDF operates massive hydroelectric dams and pumped-storage plants (mainly in France), making hydro a major driver of its low-carbon generation mix.
In the energy industry, what does the term "Churn Rate" mean?
The percentage of customers who leave a supplier for a competitor over a specific timeframe
Context: High churn means a company is losing lots of customers to rivals. Keeping churn low is a major goal for EDF's retention and sales departments.
Birds are famous for sitting safely on high-voltage power lines. Why don't they get an electric shock?
They aren't touching the ground, so the electricity has no path to flow through them
Context: Electricity always wants to find the easiest path to the earth. Because a bird is only touching one wire and not the ground (or another wire), the current just bypasses them and stays on the wire.
In which country is EDF headquartered?
France
Context: Its main global headquarters are in Paris, though it has huge operations elsewhere (like EDF Energy in the UK).
What is the primary purpose of a customer service team at an energy supplier like EDF?
To help customers manage their accounts, understand bills, and resolve issues
Context: Customer service is the "frontline" of the retail business, focusing purely on assisting the people buying the energy.
Which of these is a "renewable" energy source that EDF invests in, meaning it naturally replenishes and never runs out?
Solar power
Context: Solar, wind, and hydro are the core pillars of renewable energy because they rely on natural, infinite cycles rather than burning fossil fuels.
What is the primary reason an energy supplier's Win-Back team will reach out to a customer who recently switched away?
To offer a better tariff, discount, or incentive to convince them to return
Context: Win-back teams are highly specialized. They approach ex-customers with tailored deals to show that the company values their business and wants to fix whatever caused them to leave.
In 2013, a power station in London experienced a bizarre temporary shutdown. What animal managed to chew through a critical cable and turn off the lights?
A hungry squirrel
Context: Rodents are the secret nemesis of the power grid! Squirrels love to gnaw on things, and they are responsible for hundreds of minor power disruptions worldwide every year.
What do the letters EDF originally stand for in French?
Électricité de France
Context: Founded in 1946, the name translates directly to "Electricity of France."
Which digital tool does EDF provide to help customers check their energy usage, submit meter readings, and pay bills 24/7 without calling in?
The EDF mobile app and online account portal
Context: Like most modern utilities, EDF heavily emphasizes digital self-service tools so customers can manage their energy at their own convenience.
What do we call a large collection of wind turbines grouped together to generate massive amounts of electricity?
A wind farm
Context: Just like crop farms take up large plots of land, these groupings of clean energy generators are universally called wind farms (or solar farms for panels).
When an EDF sales representative is trying to sign up a new customer, which document does the customer need to provide so the sales rep can accurately estimate their future costs?
A recent energy bill from their current supplier showing their annual usage
Context: To give an accurate quote, sales reps look at the customer's actual consumption history (measured in kilowatt-hours, or kWh) rather than just guessing.
Some renewable energy projects get creative with lawn care. What animal is frequently hired by solar farms to "mow the grass" around the solar panels?
Sheep
Context: "Solar grazing" is a huge trend. Sheep are the perfect height to walk under the solar panels and eat the grass without chewing on the electrical wires (unlike goats or cows, who tend to destroy equipment).
EDF is famous for generating the vast majority of its electricity from which low-carbon energy source?
Nuclear power
Context: France relies heavily on nuclear energy, making EDF one of the largest nuclear operators in the world.
If a customer is struggling to pay their energy bill, what is the best first step the customer service team will recommend?
Contacting EDF immediately to set up an affordable payment plan or look for support schemes
Context: Energy suppliers have dedicated teams and regulatory duties to help customers in financial distress, often offering repayment adjustments or directing them to hardship funds.
EDF Renewables builds turbines both on land and out at sea. What is the industry term for wind turbines built out in the open ocean?
Offshore wind
Context: Built on land is "onshore," and built out in the water is "offshore." Offshore wind farms tend to be larger and capture stronger, more consistent sea breezes.
To help win over environmentally conscious customers, EDF sales teams often highlight tariffs that guarantee 100% of the electricity supplied matches zero-carbon or renewable generation. What are these tariffs usually called?
Green Tariffs
Context: "Green tariffs" are a powerful sales tool. They assure customers that for every unit of electricity they use, the supplier buys or generates a unit of renewable energy to feed back into the national grid.
Electric eels are real creatures that can generate strong shocks. Approximately how many volts of electricity can a large South American electric eel unleash to zap its dinner?
Up to 860 volts
Context: They use specialized cells called electrocytes. An 860-volt shock is incredibly powerful and easily enough to stun prey or deter predators.
What is the main job of EDF's retail business?
Selling and supplying electricity/gas directly to homes and businesses
Context: In the energy industry, "retail" means billing and interacting directly with the end consumer.
Why do customer service advisors ask customers to submit regular "meter readings"?
To make sure the customer's bills are based on actual energy used, rather than an estimate
Context: Estimated bills can sometimes be too high or too low. Regular meter readings ensure accurate billing (unless the customer has an automatic smart meter).
Because the wind doesn't always blow and the sun doesn't always shine, EDF invests heavily in what technology to save clean energy for later use?
Industrial battery storage
Context: Battery storage is essential for modern grid flexibility. When renewables produce extra energy on a sunny or windy day, batteries save it so it can be deployed when demand spikes.
True or False? When an energy sales team talks about a "Fixed-Term Tariff," it means the price the customer pays per unit of energy is locked in and won't change for a set period (e.g., 1 or 2 years), giving the customer price security.
True
Context: Fixed tariffs are highly popular in sales pitches because they protect customers from sudden market price spikes, making budgeting much easier compared to variable tariffs that can fluctuate.
Before modern electric alarm clocks were invented, how did people in British factory towns make sure they woke up on time for work?
They paid a "Knocker-Up" to shoot peas or tap a long stick against their window
Context: This was a real profession during the Industrial Revolution! The "Knocker-Up" would walk the streets early in the morning, using long bamboo poles or pea-shooters to rattle workers' windows until they woke up.
