Summary

Technological advances since the 1970's have been a major driver of energy efficiency growth in the US, with many operations now able to save 20%-30% of their energy use through such measures, according to George Sakellaris, president and CEO of Ameresco.

Sakellaris founded the company in 2000, coming to the US in 1965 to study engineering at the University of Maine, working afterwards for NE Electric as a start-up engineer at coal-fired power plants, he said in a recent interview with S&P Global Platts. He then did long-range planning strategy on transmission and generation.

Sakellaris said he was given an opportunity to study the economics of energy conservation, evaluating the costs to consumers of building new power generation capacity and transmission versus making better use of existing plants and power lines.

The results showed that using existing infrastructure more efficiently made more economic sense then building new power plants and associated infrastructure so they cancelled construction on some projects.

"I always wanted to prove that energy efficiency is the best supply option that we have," Sakellaris said. This is because at every facility they evaluate the company finds it can reduce energy consumption by 20% to 30%, he said.

Consumption is reduced through a combination of water reclamation, LED lighting, smart metering, intelligent microgrids, battery storage, combined heat and power or the installation of renewable energy, such as solar PV systems, according to Ameresco's most recent US Securities and Exchange Commission filing.
