An energy engineer is involved with the production of energy through natural resources, such as the extraction of oil and gas, as well as from renewable or sustainable sources of energy, including biofuels, hydro, wind and solar power.

Energy engineers are focused on finding efficient, clean and innovative ways to supply energy. They work in a variety of roles including:

  • designing and testing machinery;
  • developing ways of improving existing processes;
  • converting, transmitting and supplying useful energy to meet our needs for electricity.

They research and develop ways to generate new energy, reduce emissions from fossil fuels and minimise environmental damage.


The workload can be extremely varied depending on the sector or individual project. In general, tasks may involve:

  • being part of designing, developing and building renewable energy technologies;
  • combining renewable energy production with existing power systems;
  • arranging new supplies and negotiating tariffs with fuel providers;
  • carrying out site inspections and energy surveys;
  • designing and selecting equipment;
  • using mathematical and computer models to complete design and specification calculations;
  • carrying out lab experiments and adapting them to large-scale industrial processes;
  • preparing detailed schedules of work, feasibility studies and cost estimates;
  • checking site and ground conditions for the installation of renewable technologies, such as wind turbines;
  • negotiating service agreements and managing associated costs and revenues;
  • liaising and negotiating with fuel providers, specialist contractors, geologists and other relevant organisations;
  • contributing to sustainable energy initiatives and researching new energy methods;
  • keeping up to date with legislation and environmental standards and making sure systems and processes comply;
  • monitoring new technologies or applications and developing performance indicators;
  • developing technical expertise in all matters to do with energy and environmental control.


  • Starting salaries for energy engineers are around £20,000 to £28,000.
  • With experience, salaries of £28,000 to £40,000 can be earned and at the most senior levels it is possible to reach salaries of more than £60,000.

Salaries can vary considerably according to the geographical location, sector, size and nature of the employing organisation.

Income figures are intended as a guide only.

Working hours

Working hours also vary. Design, research and development roles are usually from 9am to 5pm, Monday to Friday. In power plant or drilling operations, hours may be based on a seven-day shift pattern. Part-time work or career breaks may be possible in some organisations.

What to expect

  • The work can be based in an office, laboratory or on-site. Site visits and field work are conducted outside and in all weathers. Some jobs may be off-shore in remote locations.
  • In some situations, it may be a very isolated job where you are the only person doing the work; in other cases, there may be strong team support.
  • Self-employment and freelance work are possible in energy or environmental consultancy, once considerable experience has been achieved.
  • Women continue to be under-represented in the profession, although numbers are increasing. Initiatives are in place to encourage more women into the industry including WISE and Women's Engineering Society (WES).
  • Opportunities exist throughout the UK and abroad.
  • The dress code tends to be conservative for meetings and it is expected that energy engineers will be smartly dressed even when visiting sites.
  • A reasonable level of fitness and mobility is required as the work can be physically demanding.
  • Travel may constitute a large part of the role, particularly if the employing organisation has multiple sites, although absence from home overnight is uncommon.
  • Overseas travel opportunities may be available with some multinational organisations.
  • A company car may be offered with some organisations, but if not, mileage for site visits is usually payable.


To become an energy engineer you need to have an engineering or scientific-related degree. Relevant subjects include:

  • earth sciences;
  • electrical, mechanical or chemical engineering;
  • environmental engineering;
  • environmental science and management;
  • mining or petroleum engineering;
  • renewable or sustainable energy.

Renewable and sustainable energy solutions are increasing in both their profile and application. This has led to a number of specialist degrees being available that focus on energy and the environment, such as energy engineering, sustainable energy and climate science.

A postgraduate qualification is not essential but it can be useful, particularly if your first degree is not in an engineering or science-related subject. Courses are available in a variety of relevant subjects including renewable energy engineering, sustainable energy systems and energy futures. Such courses can also help develop particular interests and may help to secure a more senior position.

It is useful if your first degree or Masters is accredited by a relevant professional body, such as the Energy Institute or Institution of Engineering and Technology (IET), as it can help you to achieve the status of chartered engineer at a later date. Details of accredited courses are available at Engineering Council - Accredited Course Search.


You need to show evidence of the following:

  • an interest in science, technology and the environment;
  • general understanding of the energy market;
  • knowledge of relevant legislation surrounding energy efficiency and carbon emissions;
  • good communication skills, both written and oral;
  • scientific and mathematical ability;
  • organisational and negotiation skills;
  • IT skills, including knowledge of 3D software such as AutoCAD;
  • the ability to manage change;
  • commercial awareness and an understanding of business;
  • project management skills;
  • initiative and the ability to recognise emerging problems and pro-actively develop solutions.

Foreign language skills can be an advantage for working in multinational companies.

Work experience

Most employers look for candidates with experience, so any relevant knowledge and skills you can build up through a placement as part of your course or work experience is useful. A number of the major oil and petroleum companies, including BP and Shell, offer summer and one-year internships.

You can make speculative applications for work experience with various employers. Relevant contact details can be found at Energy Institute - Company Members Directory.

It is also helpful to become a student member of relevant societies, institutes or charities. As well as increasing your knowledge of the sector and showing commitment to potential employers, it will provide opportunities to network and make useful contacts. In addition, it is important to keep track of developments and changes in the sector.


Demand for energy engineers is good as employers in all the major sectors are recognising the need to develop specialist energy posts due to increasing legislation, rising energy prices and a greater public awareness. Almost every area of industry uses a large amount of energy in its production processes; therefore there are many organisations that employ energy engineers including:

  • industrial employers;
  • fuel production industries including oil, gas and nuclear;
  • manufacturing companies;
  • government departments.

Energy engineers are also based in research departments where they research, develop and test alternative sources of energy, such as wind, solar, tidal and geothermal power.

Other potential areas where energy engineers can find work include:

  • the motor industry, helping to meet strict exhaust emission legislation;
  • the wider manufacturing industry, designing, testing and installing energy equipment to generators, turbines and engines;
