The clean-energy transition is often presented through shiny hardware such as solar panels, batteries, heat pumps, and electric vehicles. But none of those systems works without the people who pull cables, test circuits, repair faults, and keep power moving safely.<\/p>\n\n\n\n
Alfredo Becerra\u2019s career offers a ground-level look at how that work has changed. He began learning at 14, entered an electrical company at 16, and stayed in the trade for more than three decades, watching old materials disappear, safety improve, salaries shift, and knowledge move from guarded workshop tricks to public online tutorials.<\/p>\n\n\n\n
When Becerra was 14, he left school and spent his afternoons helping a local man with small repair jobs. That was where he learned to recognize basic tools and began to understand the rhythm of hands-on work.<\/p>\n\n\n\n
In 1978, at 16, he joined the company that would define most of his working life. Apprentices<\/a> then advanced through four levels before taking a test to become a third-class journeyman, followed by further steps toward first-class status or specialist work.<\/p>\n\n\n\n It was a slow ladder. But it tied promotion to years of practical experience, and the pay difference between a beginner and a skilled worker gave people a clear reason to climb it.<\/p>\n\n\n\n Becerra first worked with radiant ceiling wiring and heat-storage units, systems that later became outdated. He moved into public lighting<\/a>, commercial installations, and eventually low- and medium-voltage networks, where strength mattered almost as much as technical judgment.<\/p>\n\n\n\n Cable reels were moved and unrolled largely by hand, using heavy jacks to support them. Today, a passerby may only see a utility crew beside an open cabinet, but the older version of the job often meant wrestling with the infrastructure itself.<\/p>\n\n\n\n The materials added another layer of difficulty. Becerra remembered Bechman conduit, cloth-covered cable, and installations in which conductors were all the same color, turning future repairs into something close to electrical detective work.<\/p>\n\n\n\n Specialized products were not always available, so workers improvised. Becerra recalled colleagues pouring beer onto a stubborn cable run and admitted that he sometimes used traditional hard soap as a makeshift lubricant.<\/p>\n\n\n\n He did not defend those practices. \u201cYou cannot do that, but they did it,\u201d he said about the beer, capturing an era when ingenuity often ran ahead of formal procedures. The lesson is not that the old ways were better, but that modern tools and standards<\/a> have helped reduce hazards workers once treated as normal.<\/p>\n\n\n\nThe job was heavier and less forgiving<\/h2>\n\n\n\n
Improvisation filled the gaps<\/h2>\n\n\n\n
