Who We Are

How we started

Building on his experience and professional background in Computer Engineering and renewable energy, Extreme Low Energy (ELe®) was established by Mark Buchanan in 2014.

Mark recognised that while our power supply is globally standardised on AC (Alternative Current) transmission, many of today’s everyday electrical products such as computers, TV’s and LED lighting run on DC (Direct Current) power and as a result, require bulky, inefficient, energy wasting transformers.

Identifying the potential energy and carbon savings that could be achieved by eliminating the wasteful AC/DC conversion process, Mark created a groundbreaking DC Power infrastructure. In developing the system, he designed a method of distributing the DC power safely and efficiently through a building’s existing Ethernet cabling, cutting out the need for any additional cabling. He further developed and advanced Lithium-ion Battery Storage and Power Distribution System to enable even greater energy savings to be achieved.

While the design and supply of DC storage and distribution is currently ELe®’s core business, Mark has since developed the system to operate with renewable energy sources. He has also designed specially adapted, high performance DC-based devices including computers, monitors, servers and LED lighting systems to create complete end-to-end capability.

Where we are now

In the UK, ELe®’s award-winning technologies are now being recognised a Leisure POD offgrid glampinggame-changing for how we will power computing for our schools and businesses in the future. With its simple ‘plug and play’ installation the system is easily retrofitted via existing CAT5E/CAT6 cabling. For new builds, the potential is even greater as it changes the way buildings are designed for maximum efficiency and return.

Our low energy infrastructures for modular buildings are now enabling more sustainable space solutions for affordable housing, student and senior living accommodation.

In Africa, ELe® is also beginning to open up a world of opportunities for delivering educational, medical, financial and community services to regions with unreliable or non-existent power supplies. The potential for replacing UPS or back-up generators and for utilising Africa’s solar energy resources with ELe®’s DC infrastructures is unlimited.

Where we are going

As an innovative and growing business, ELe® continues to develop new technologies for sustainable energy management. We welcome new ideas and opportunities for eliminating energy waste and reducing cost and carbon impact.

As we grow, we are building a global network of partners to reach new customers and to work with us to build on the potential of our unique technologies. If you would like to discuss potential new opportunities for ELe® DC infrastructures, drop us a line at: info@extremelowenergy.com or call: +44 (0) 1695 731 942.



Our Ethos & Mission

While our focus is always to deliver sustainable infrastructures and to do so with a demonstrable ethos of partnership, our approach is always collaborative. We believe that by better understanding the needs of our customers, we can best position ourselves to advise on technologies and implementation that are not only fit for purpose, but truly deliver value.

Our mission is a simple one: to help entities of every nature to reduce energy usage, to mitigate carbon emissions and to deliver services and education where there were none, thereby protecting the environment and the world in which we live. In developing countries we aim to change the way electronic devices are powered and in emerging markets we will seek to offer off-grid solutions as and where they are most needed.

In everything we do, we will make progress and sustainability our key drivers.
