WELLESLEY, Mass. - Sept. 15, 2025 - As the United States accelerates its shift toward renewable energy, the need for engineers skilled in both legacy and future power systems has become critical. John Cromer, P.E., a mechanical engineer who began his career designing control systems for the oil and gas industry, is now at the forefront of this transition, training professionals on the practical application of solar and battery storage technology.
With 12 years of experience designing and installing complex solar photovoltaic projects, Mr. Cromer embodies the energy transition. His unique career path gives him a deep understanding of the challenges and opportunities involved in moving from a fossil fuel-based grid to a decentralized, renewable-powered one.
"The future of energy isn't about flipping a switch; it's a complex engineering challenge that requires a new way of thinking," said Neil Harper, Founder and CEO of PDH-Pro, an online continuing education platform. "John's journey from oil and gas to renewables gives him a powerful perspective. He doesn't just teach solar theory; he teaches the hands-on, practical knowledge needed to integrate these new technologies into our existing infrastructure safely and effectively."
Mr. Cromer, a Master Electrician and NABCEP Certified PV Installer, emphasizes the importance of understanding the National Electrical Code (NEC) as it applies to new technologies. His courses focus on demystifying concepts like residential battery storage, smart home load control, and the latest NEC updates on rapid shutdown protocols.
"My time in oil and gas taught me the importance of robust control systems and safety protocols," stated Mr. Cromer. "I now apply that same rigor to renewable energy. The goal is to equip engineers and electricians with the confidence to design and install solar and battery systems that are not just efficient, but also fundamentally safe. This is how we build a resilient and reliable clean energy grid for the future."
