Our Team

Thomas Chadwick

Chief Executive Officer

Tom is defined by his vision and desire to realize it – from leading a top rated team at Merrill Lynch, to building a sustainable home, or catching trout in Pakistan. His vision today is just a little bolder: build a unique and outstanding US sustainable energy business. Six years at Deloitte taught him respect for the numbers; they’re the ultimate measure of success. At Merrill Lynch he saw the transformation and renewal of Eastern Europe and over 16 years dealt with huge change. He witnessed what talented people achieve with great ideas and customer focus. He also identified a new challenge – a need for smart, flexible, low-cost sustainable energy and a reduction in carbon emissions. In 2005 he founded GI Energy in the UK. He applied engineering excellence to clients’ needs. GI grew fast and a US launch followed in 2010. In 2013 Tom moved to Chicago. Within two years the company was three times the size of its European sibling. Tom remains extremely ambitious for the business, but hopes to find time to catch big trout here too...
