Energy trading interviews test how well you understand the markets themselves — power and gas, the physical side of sources, conversion, and storage, and the structures and regulation that shape how they trade. Expect questions on market participants, the instruments and products traded, and the economic factors that move prices. The examples below sit at the difficulty asked across trading houses, utilities, and bank commodity desks.
Sample Questions & Solutions
Each question is a real interview problem. Try it yourself first, the full solution is revealed below.
Regulated vs. Deregulated
EasyShow solution
- In regulated markets, a single entity, usually a government-appointed or owned utility, controls the generation, transmission, and distribution of energy. Prices are set by regulatory bodies. In contrast, deregulated markets allow for competition among multiple generators and suppliers, with prices often determined by market forces.
- Deregulation aims to increase efficiency and lower prices through competition, though it requires robust regulatory oversight to ensure fair practices.
Green Bonds

Definition
Green bonds are fixed-income securities whose proceeds are exclusively used to fund projects that have positive environmental impacts. They often require third-party verification to ensure that the funds are used for green projects, adhering to standards like the Green Bond Principles.
Role in Financing Renewable Energy Projects
Green bonds provide the necessary capital for large-scale renewable energy projects, such as wind farms, solar power plants, and hydroelectric facilities. In 2019, the European Investment Bank issued a €500 million green bond to finance renewable energy projects across Europe. Green bonds often come with lower interest rates compared to conventional bonds, making them an attractive financing option for renewable energy developers. On the other end, green bonds attract environmentally-conscious investors who are interested in supporting sustainable projects, thus broadening the investor base. By financing renewable energy projects, green bonds contribute to broader sustainable development goals, including reducing greenhouse gas emissions and improving energy access.
Ensuring that green bond proceeds are used as intended requires robust verification and reporting mechanisms. The lack of standardized criteria for what constitutes a green project can pose challenges for issuers and investors. In emerging markets, the green bond market is still developing, and there may be a lack of awareness or expertise in issuing and investing in green bonds. Supportive regulatory frameworks are important to encourage the issuance and uptake of green bonds. Governments and regulatory bodies need to provide clear guidelines and incentives.
Supply Chain Disruption
EasyShow solution
Another examples is when due to a war or technical problems, oil can't be shipped from A to B. This will lead to a supply problem, resulting in higher oil prices.
Supply chain disruptions can delay the construction and commissioning of renewable energy projects, slowing the transition to cleaner energy sources. Also, uncertainty caused by supply chain disruptions can make it more difficult to secure financing for energy projects, leading to delays or cancellations
Why practise these
In energy, trading and physical reality are inseparable — generation, transport, storage, and the regulation around them all feed into the price. These questions test whether you understand those mechanics, rather than treating energy like any other asset.
