Energy Letter Campaign

We invite you to join our energy letter campaign.

If you visit an overheated shop, office, café, church or any public place we have prepared a letter template for you to send which asks them to lessen the environmental impact of their energy use and suggests ways they could do that.

Please use the following letter, or download it from here, and adapt it to suit the particular shop, office, café, or church etc that you wish to write to.



Re: Enquiry about energy use at your premises

Dear Madam / Sir,

I was in your premises recently and found them to be overheated. I decided to write to ask you to consider some suggestions about energy use which could reduce climate change and cut your energy bills.

Climate change is being caused because we are putting far too much greenhouse gas into the atmosphere. I feel it is important to look after our world for future generations, and that we can all do our part.

Firstly, I would ask you to follow the World Health Organisation’s recommendation of heating buildings to no more than between 18 and 22 degrees Celsius. Heating your building to a lower temperature would of course reduce carbon dioxide emissions and expenditure on fuel.

Secondly, have you considered using a green energy supplier’s Dual Fuel Tariff for gas and power? While all energy production and consumption has some environmental footprint, renewable energy presents an opportunity to lessen that impact significantly – particularly as the fossil fuel industry’s dependency on unconventional and more polluting sources grows – for instance, tar sands, heavy oil and oil shales.

And thirdly, now that more and more buildings have fitted rooftop solar electric (photovoltaic or PV) panels, might you follow suit? Small-scale generation has become an important move away from centralised power distribution, ensures security of supply, and, with the Government’s Feed-in Tariff, could prove a lasting investment.

I hope that you will be able to support one, or all, of these ideas, and so contribute to a new energy future.

Yours sincerely,

Thank you for this well-informed initiative. I am intending to have an eco-hints page on our website and will definitely recommend that our parishioners use this letter.

Excellent initiative, thank you. Reminds me of the Leicester Friends of the Earth 'open shop door campaign' some time in the last millennium. I can dig out some photographs if anyone is interested.
