The world is facing an unprecedented energy crisis: production is at capacity at a time when new demand – from buildings, electric vehicles and AI data centers -- is growing fast.

However, the crisis isn't just about supply — it's about waste.

According to the U.S. Energy Information Administration, our current energy systems are highly inefficient, wasting about half of the energy they produce. This waste occurs during the energy generation process, with additional losses happening as electricity travels from power plants to our homes and businesses.

"We have to do more using less, and the only way you can get at it is efficiency," says Jonathan Maxwell, who leads SDCL, a global firm specializing in environmental infrastructure investments.

Maxwell was speaking on a recent episode of JLL's global podcast, "Trends & Insights," alongside Guy Grainger, JLL's Head of Sustainability Services.

The two discussed the untapped potential of energy efficiency. For instance, how cities are taking innovative approaches to address energy challenges.

In London, a joint venture between the mayor's office and private investors has created a GBP100 million ($126 million) fund focused on decarbonization through efficient and decentralized energy generation.

Grainger says it’s the reason why “city mayors are paying so much attention to energy efficiency, because actually it's harder in a built-up area to get those on-site solutions very close to the user."

In commercial real estate, businesses are finding that efficiency measures not only cut costs but can also provide a competitive edge.

Take data centers, which are facing increasing energy demands and grid constraints. They’re turning to on-site generation and efficiency measures to ensure reliability and meet growth needs.

"The projects that I've described to you can take a few months, maybe a year or two to design and implement," Maxwell says. This is in stark contrast to large-scale energy projects that can take a decade or more to come online.

However, challenges remain.

"The trouble is that energy efficiency isn't as sexy as building a power,” Grainger says.

Despite these perception issues, the urgency of the situation is driving action.

"This isn't just about efficiency or hope – it's about the very real risk of critical systems going dark. Many grids are on the brink, and blackouts are still a reality in numerous locations,” Grainger says. “There simply isn't enough energy to fuel the economic growth everyone desires. The fear of a critical asset – be it a data center, lab, or manufacturing plant – losing power is what drives executive decision-making.”
