Guest Speakers
Tanya Ewing
Will You Be A Green Entrepreneur?
Tanya Ewing was recognised as “British Female Inventor of the Year 2008” for her creation of a real time energy monitor Ewgeco (pronounced You-gee-co). Tanya wanted to bring meter information out of cupboards for all to gain a greater understanding of household&small business energy and water consumption. Unable to find such a device, she took it upon herself to develop one using a unique traffic light display system.
With no previous engineering or design experience, Tanya worked with technicians who could make her idea a reality. This all came at a hugely challenging time in her personal life. Due to a debilitating illness, Tanya had been unable to work for 7 years and was undergoing IVF treatment.
Her business is expanding and her story is held up as an example of pure determination in pursuit of a good idea. Tanya is passionate about the impact that Ewgeco can have on reducing the utility bills alongside the environmental benefits of reducing consumption and taking energy-conservation methods. She won the prestigious Glenfiddich Spirit of Scotland Award for the Environment in 2008.
