Energy auditors, also known as energy raters, are specialized consultants who help improve the energy efficiency of structures of all sizes. Energy auditors can work on the residential level or the commercial level, plying their trade for homeowners and business owners alike. As part of the “green" energy business sector, careers as energy raters present ample opportunities for advancement over the coming decade. As a matter of fact, a large number of energy industry analysts anticipate that the alternative energy sector will continue to expand at a much faster pace than expected. Energy consumers as a whole are becoming increasingly environmentally conscious, which has created a comfortable niche market in which energy auditors can earn a living. A bigger driving factor in the business of energy auditing is the rising cost of energy, primarily residential electricity costs. Similar to the average price of gas, the price of electricity has been on an upward trajectory for the last few decades. Energy raters and auditors provide clients with actionable, real-world advice that can save hundreds, if not thousands, of dollars annually. Providing individuals and businesses with a means of reducing the cost of energy is the hallmark quality of energy auditors around the world.

A roofer is a professional who specializes in roof construction. Roofers monitor the entire process of roofing in residential as well as commercial construction. They analyze the construction plans and make sure that the roofing is done in strict accordance with the design. Roofers also determine the materials, substrates and supportive accessories to be used for roof installations. Even the specifications of the beams, trusses and rafters upon which roofs are installed are decided by roofers. Not only do they work on new installations, roofers also work on renovations and roof repair projects. As expected from the job title, roofers ususally need to climb onto rooftops to work. A roofer should therefore not be afraid of heights and should have good balance, as well as reasonable carpentry skills.

The term "rigger" originated in the days of sailing ships when sailors were responsible for raising and maintaining a complex system of sails and rigging. In modern usage, it generally refers to someone who sets equipment up and prepares it for use. According to the U.S. legal worker definition, a rigger is anyone who attaches or detaches lifting equipment to loads or lifting devices. There are a number of different categories of riggers working in several industries. In the military, riggers are responsible for maintaining and setting up things like parachutes or airdrop equipment. In the theater industry, riggers manage pieces of a stage set, moving props and changing production scenes. Riggers in the marine industry are involved with setting up the pieces of equipment necessary to keep the ship functioning: ropes, pulleys, winches, cables. Most commonly, however, jobs are found within heavy construction, often in the oil or mining industry. This type of rigger is also referred to as a Rig Technician. In the oil industry there are several levels of Rig Technicians, ranging from motorhands to derrickhands to drillers, depending on skill level and job duties. Riggers in this industry are responsible for attaching pieces of heavy machinery, connecting the parts together and anchoring pieces to fixed structures with bolts and clamps. They also control and manage all the movement of the machinery while it is operational, and then take it all apart when the job is finished.

Traffic technicians, also known as traffic technologists, are skilled workers who specialize in the technical aspects of controlling and studying vehicle traffic. A more general job title for traffic technicians is civil engineering technician, but more often than not, traffic technicians focus exclusively on issues involving roadways. Civil engineering technicians, on the other hand, handle a much broader range of responsibilities such as working on building construction sites. Traffic technicians may work on newly constructed roads, but usually they perform more duties that are related to maintenance. Traffic technicians are professional engineering specialists who work under the guidance of a civil engineer in most cases. Occasionally, traffic technicians fulfill the role of researcher and data collector when assisting a civil engineer. Expanding a decades-old interstate highway, for example, requires a large amount of data collection in order to accommodate modern traffic flow. Without the real-world expertise of traffic technicians, civil engineers would not be able to apply experimental concepts.

An actor is someone who plays characters in a film, television, radio, or theatre production. When most people think of actors they think of Hollywood superstars who perform in blockbuster films and this is often the ultimate aspiration of anyone dreaming of a career in acting. There are also stars within different fields of acting. For example there are well-known television and theatre stars in each discipline. It is difficult to achieve this degree of success in the field of acting, and the majority of actors perform in smaller productions, often starting in advertisements or as extras on television shows or films. There are many actors who make a successful career out of so-called bit parts and never have a starring role. Others, who achieve great success very early in their careers, become household names and get lots of major roles. The majority of actors will have a career that is somewhere between these two extremes.

Petroleum, or oil, has been utilized since prehistoric times to provide warmth and light, in warfare, and for medicinal purposes.

A Mine Shuttle Car Operator is part of the mine operation career area, generally working in underground mines, but sometimes in open-pit mines as well. There are many different jobs that go on inside a mine and the shuttle car operator is just one of them. Mining has a long history in most parts of the world. The shuttle car operator has been there right from the start. Many mining museums, such as the Atlas Coal Mine Historic site in Drumheller, Canada, allow visitors to get a sense of how shuttle cars were used to travel through the depths of the mine during the early days of the coal mine industry. Workers in mines face many dangers and the shuttle car operator often must travel to the farthest depths of the mine. Early mine camps were called hell's hole, not only because of the poor camp conditions, but because of the inherent danger involved in going underground. In the early days mining was hard, dirty work. It still is. Mining has always been considered a dangerous profession, and although safety has improved with new technology, mining accidents are always a concern and can happen anywhere. Car operators have been crushed between cars, had rocks or ceilings fall on them, or been electrocuted by faulty or loose cables. In 2010 the Copiapo mine in Chile provided an example of both the extremes of danger and the miracle of survival. That cave-in and subsequent near-impossible rescue of 33 miners after 69 days serves as a testament to the unique and resilient nature of the people who choose to work far below the earth. Modern mining has advanced and changed, but the hardy, brave and durable nature of the people who choose this profession has not.
