What does an electrical engineer do?
Electrical engineering is a very diverse discipline of engineering. Electrical engineers design, develop, test, and supervise the manufacture of electrical equipment, such as electric motors, radar and navigation systems, broadcast and communications systems, power generation equipment, and electrical distribution systems.
They also work on the development of new technologies in areas such as renewable energy sources, energy storage, and energy conservation. Electrical engineers also work to make electronics and electrical devices more energy efficient.
Electrical engineers typically have a bachelor’s degree in electrical engineering. Some electrical engineers also have a master’s degree or doctorate, particularly those who are involved in research and development or academic areas.
3. Civil Engineers
Civil engineering (CE) is one of the oldest and most important disciplines of engineering. It’s responsible for the design, construction, and maintenance of essential infrastructure projects such as bridges, roads, tunnels, canals, dams, and buildings. Without civil engineers, our world would be a very different place indeed.
Civil engineering is the third most popular engineering discipline in the US, with over 21,000 undergraduate degrees awarded annually. The average salary for civil engineering majors in the United States is $82,284 per year. 
Civil engineering professionals will be in high demand as the world’s population expands since more and more infrastructure must be developed. Employment of civil engineers is anticipated to rise by 8% from 2020 to 2030, according to the US Bureau of Labor Statistics. 
What does a civil engineer do?
Civil engineers design and oversee the construction of infrastructure projects such as skyscrapers, bridges, roads, dams, airports, and water and sewer systems. They also work on environmental projects such as cleaning up polluted areas, developing plans to manage solid waste, and researching ways to prevent flooding.
Civil engineers are also responsible for the maintenance of existing infrastructure. This includes inspecting bridges and dams to ensure they are safe and repairing or replacing infrastructure that is no longer operational.
In order to become a licensed civil engineer, you must have a four years bachelor’s degree in civil engineering from an accredited engineering program.
4. Computer Engineers
Computer engineering is defined as the discipline that embodies the science and technology of design, construction, implementation, and maintenance of software and hardware components of modern computing systems and computer-controlled equipment.
This is a relatively new discipline in engineering. In fact, it combines the principles and concepts of computer science with electrical engineering to develop computer hardware and software.
Computer engineering is the fourth most popular engineering discipline in the US, with over 15,000 undergraduate degrees awarded annually. The average salary for computer engineering majors in the United States is $93,782 per year. 
What does a computer engineer do?
Computer engineers are responsible for the design and development of computer hardware and software. They work on various components of computing systems, such as processors, memory chips, and circuit boards. They also develop new computer technologies and applications.
Computer engineers make sure that computer hardware works properly with the latest software technologies. They also work on optimizing existing computer systems to make them faster and more efficient.
In order to become a computer engineer, you must have a four years bachelor’s degree in electronics engineering & computer science, or software engineering to be able to work in this field.
5. Energy Engineers
Energy engineering is the branch of engineering that deals with the generation, distribution, and utilization of energy. The goal of energy engineering is to ensure that our energy systems are reliable, efficient, and sustainable. The key focus area of energy technology engineering is renewable energy & its systems.
