Biomass is a form of stored solar energy and is available in a number of different forms. These include wood, straw, energy crops, sewage sludge, waste organic materials and animal litter.
Although burning biomass releases carbon dioxide to the atmosphere, this is offset by the carbon dioxide absorbed in the original growth of the biomass, or captured in the growth of new biomass to replace the materials used. As a result, using biomass for heating/electricity generation results in very low net ‘lifecycle’ carbon emissions relative to conventional sources of heating, such as gas, heating oil or electricity.


Biofuels are any kind of fuel made from living things, or from the waste they produce. We use the term biofuels to encompass any alternative substitute for petrol or diesel or other liquid fuel made from processing plant material or waste oil.

Biofuels are not a recent development, they have been around as long as cars have. At the start of the 20th century, Henry Ford planned to fuel his Model Ts with ethanol, and early diesel engines were shown to run on peanut oil. They have though seen significant attention recently due to humanity’s ever-dwindling supply of natural resources or more specifically our over-dependence on fossil fuels.


Hydropower is one of the most efficient ways to generate electricity in the right locations.  C.16% of the world’s energy is generated by hydro schemes.  Hydro power is also incredibly versatile, providing the ability to increase/decrease output very quickly in response to demand.  The UK has a lot of untapped potential in the sub 1MWp market (small/medium)

Renewable Heat

We use more heat than electricity in the UK, however a unit of electricity is generally more expensive than a unit of heat – hence the focus within the renewable energy world has been more about electricity.  This should diminish the technologies or the taking advantage of the opportunities there are to generate heat from renewable sources.

Solar PV

Solar power is the conversion of sunlight into energy. Panels (or photovoltaic panels if you prefer) generate DC power which is then converted into AC before being fed into the grid or a building’s supply

Whilst a nice sunny day will generate excellent output, the PV can produce energy on cloudy days, it is daylight that is required.

The beauty of solar in the context of UK Commercial property is that you are using space that has hitherto been unused (no ‘land cost’)and you can generate electricity to decrease grid usage and therefore reliance on ‘brown’ power.


The UK has some of the best wind resources in Europe that can be used as a low carbon renewable energy supply, to help meet our security of supply and climate change goals,

Onshore and offshore wind generation can make a significant contribution to the UK’s renewable energy targets and aspirations given the UK’s substantial wind resource and the relatively advanced nature of wind generation technology. The UK already has more offshore wind capacity than any other country in the world.

The combination of hands-on real estate asset management experience together with their obvious technical ability is what set them apart when assessing who to work with. We have been delighted with the work carried out and would have no hesitation in recommending them to other property owners

Ben Buckley-Sharp (Director), Aberdeen Asset Management

Syzygy handled the whole process from advising on the size of the installation, producing initial designs, tendering and project management. They delivered the project on time and on budget and are now managing and monitoring the the installation on an on-going basis... Gunwharf Quays now has the largest solar PV system on a shopping centre in the UK and has been nominated for UK Renewable Energy project of the year, which we are very proud of. We were very pleased with their work and would have no hesitation using them again and indeed recommending them to others. 

Rowan Packer (Energy Manager), Land Securities

Syzygy managed a retro-fit PV project for us at our Crystal Peaks Shopping Centre in Sheffield. They took the project from identifying the opportunity, producing the financial appraisals through to delivering the final installation and now they monitor it for us. We felt it was important to use an experienced specialist consultancy to run this project for us, and have been very pleased with Syzygy's work to this end. The installation was delivered on time and ahead of initial budget estimates. In summary, they handled all aspects of the project, including tendering the contract and monitoring the contractor, making what was a high profile project very simple for us to deliver. Our local team was particuarly impressed with their ability to work without affecting the day to day operation of the centre.

John Macdonald-Brown


"What we are seeing now as regards current and future legislation and policy-making is a very clear sign of where the agenda is being driven"

John managed commercial property funds from 1999 to 2009, at Ashtenne Holdings and subsequently at Spitfire Estates.  In this period John managed investment from AXA REIM, BlackRock and Lasalle IM.  

“The sustainability agenda has been the elephant in the room for many commercial property owners. What we are seeing now as regards current and future legislation and policy-making is a very clear sign of where the agenda is being driven. 

Planning requirements, 2018 minimum EPC requirements, 2019 zero-carbon development and the CRC regime to name but three….it is incumbent on property owners to introduce measures to improve building performance both in terms of reducing energy usage but also in finding ways to generate renewable energy on-site, it is going to be much more cost effective in the long run for those that take decisions now than it will be for those have changed forced up on them in later years.”

John set up Syzygy in 2009 aiming to help bridge the two worlds of renewable energy and commercial real estate.  Providing practical advice and to deliver well thought out and relevant renewable energy solutuions to property owners and occupiers.

Away from work John sails when he can, plays cricket, and occasionally golf.  In the winter, he can be found at most London Scottish home games, as a retired 1st XV player he is happy to bore the young athletes with advice on what it was like in his day!

John is married to Anna and they have two children, Tommy and Kitty.

Neil Sinclair


"Not being a contractor nor being wedded to any technologies really does allow us to deliver the optimum renewable generation solution for our clients"

Neil worked for 14 years at various financial institutions in London trading Emerging and European equities. His interests however lay elsewhere within renewable energy so in 2008/9 he completed a Masters at London business school and went on to set up and run a renewable energy contracting business, which he sold in 2011 prior to joining Syzygy. Neil brings practical experience in several of the major technologies as well as financial know how.

Away from work Neil loves to golf, ski and occasionally play tennis.
Neil is married to Bryony and they have three children, Cammy, Alex & Lochlan. He hopes all his boys play rugby for Scotland but if they fail to make the cut, the good news is they are eligible to play for England.
