Majority of residents believe London should be a leading solar city

A vast majority of residents believe London should become a leading solar according to the results of new research conducted by Greenpeace UK
Majority of residents believe London should be a leading solar city

Environmental group Greenpeace UK commissioned an independent poll which highlighted that 70 percent of voters in London, UK, which is embroiled in a race to decide its next city Mayor, believe that it is important the next Mayor takes action to ensure the capital plays a bigger role in the development of solar energy.

The findings come less than a month before the vote, in which all the leading candidates have stated in principle that they would vastly increase solar capacity. However, less than one percent of London’s 3.4 million households currently have solar and the city trails behind in uptake in the technology at both national and international level.

“It is clear that delivering a cleaner, greener city matters to Londoners, and they will be thinking about these issues when it comes to voting on 5th May” said Diana Vogtel, Energy Campaigner at Greenpeace UK. “Greenpeace and its partners have been calling on all candidates to set out clear plans to solarise London and we see a key role for the next mayor in defying the government’s cuts on solar power, to ensure the industry thrives in the Capital. A world leader in many other fields, London is a world laggard when it comes to solar power. The next mayor has the chance to change that.”

The poll revealed that more than 80 percent of Londoners welcome the idea of solar panels being placed on Transport for London (TfL) buildings by way of powering the city’s new fleet of electric buses.

At a London mayoral hustings last month, all the leading candidates laid out their green manifestos and confirmed they intend to increase London's solar capacity by tenfold over the next 10 years, rolling out solar across an equivalent of close to 200,000 London rooftops by 2025.

Whilst, as the owner of 3 all-electric electric vehicles (EVs) - and an EV-related business, I am delighted (and surprised) at this news, there has got to be a bit of realism injected into proceedings. Firstly, are we prepared for a huge number of our attractive victorian house roofs to be ‘vandalised’ with the wholesale application of typical photovoltaic (PV) arrays? There is, of course, a great deal that can be done to reduce the impact, particularly in London where intelligent use of ‘integrated’ (ie within the thickness of the roof covering) PV could be used, especially so considering modern PV is almost black and this tends to blend in with typical London slate roofs. Secondly, even if all of TFLs roofs were covered with PV it would still not even come close to generate enough energy to run all TFLs buses were they all electric. You can only get about 0.15kW of electrical energy from a square metre of PV in ideal conditions. So, on an ideal summers day your 1 square metre of PV will generate about 1 kWh of electricity. A typical double decker uses about 2kWh per mile which works out at about 1.6GWh of electricity per day on average for all TFLs 9000 busses, collectively doing 300 million miles annually (2011). So, ignoring the fact that all the energy generated from the PV would have to be stored (as buses would have to charge at night and the sun don't shine then) you would need 1.6 million square metres of PV to supply TFLs bus fleet… the area of about 160 major-league football pitches. That’s the bad news. The good news is that - by way of an example - one of my EVs is a Peugeot iOn, a re-badged Mitsubishi i-MiEV, a fabulous, small (4 proper seats) EV, ideal for local driving (tho it can be used for long trips - they just take 50% longer!). It is used for my typical 45 mile per day commute (50% more than the average daily UK car mileage, BTW). I also have a 1.2kW (peak) PV array on my garage roof which is subject to quite a bit of shading. Nonetheless, in its first year of operation the array offset fully 2/3 of the electricity used by my iOn. It is not unreasonable to imagine that without the shading issues, it would have offset all of it. It is also not unreasonable to imagine that that 1.6 million m2 of roof would probably equate to London's big supermarkets alone, let alone all the other commercial roofs out there. Personally, I would like to see a government decree (or at least a mayoral one) stating that *every* new building must have a certain amount of aesthetically sympathetic PV installed and those commercial ones with large roof areas (eg supermarkets etc) must have at least 50% of their roofs covered with PV and they would have to pay (if necessary) for the local grid to be up-graded to cope with the output *or* pay to have adequate electrical storage installed within the new building to avoid stressing the local grid. Government incentives could apply!
