50 Most Admired Companies of The Year 2017

“Through energy audits, innovative engineering, renewable solutions and deep energy retrofits, we apply forward-thinking technology to the challenges of reducing energy costs, controlling emissions, and enhancing energy security”: Ameresco


Renewables are great for our energy portfolio because they are inexhaustible and won’t pollute the planet for us or future generations by emitting toxic chemicals and gases. While some regions and countries have grown wealthy and benefitted from their proximity to coal, gas, and oil reserves, not all places have access to fossil fuel, which has made economic development difficult in some areas. However, nearly every location has access to sunlight, wind, and the geothermal power from the Earth, so harnessing these sources of renewable energy could be a great democratizing force, offering affordable and plentiful power to almost all corners of the globe.

While increased energy use clearly has many benefits, we are also becoming increasingly aware of the negative impacts of energy use. We experience these negative impacts globally and locally in the form of climate change (and the associated effects) and degradation of local environments in terms of poor air quality, degradation of soils (leading to desertification in extreme cases), resource depletion (e.g. water) and noise pollution. However, more efficient use of energy at all stages of the supply/demand chain could reduce the negative impacts of energy consumption, while still allowing the same economic development.

By utilizing the benefits of renewable sources and energy efficiency, Ameresco caught the eye of those enterprises which were looking for these services. Passionate in his belief towards energy efficiency, Mr. Sakellaris founded Ameresco in 2000. He aspired to build a product-neutral and supplier-independent energy company with the skills, capabilities and foresight to create independent energy solutions to resolve each customer’s unique requirements. He built a company that not only addressed conservation measures, but also focused on the customer’s entire energy stream including supply and demand, energy efficiency and renewable energy.

Ameresco, Inc. is a leading independent provider of comprehensive energy efficiency and renewable energy solutions for facilities throughout North America and the United Kingdom, delivering long-term value through innovative systems, strategies and technologies.
