Don’t let climate change outsmart you: make your Earth Hour last all year


Well-known baker Ian Cumming shares his smart resolutions for making Earth Hour last through 2017 and beyond.

To celebrate the 10th anniversary of Earth Hour, which falls at 8.30pm on 25th March, Ian Cumming, well-known TV baker and travel photographer, has pledged to make his Earth Hour last all year. He’s come up with some easy, try-at-home resolutions to encourage others to do the same, using feedback from his smart meter as inspiration, and also developed a new energy saving recipe with the help of his smart meter.

From being innovative with natural heat sources, to using his smart meter to help reduce energy waste, Ian’s Earth Hour resolutions show that getting smart about climate change starts with small, thoughtful changes at home.

Earth Hour is a global environment movement run by WWF and volunteer organisations. It’s the world’s largest demonstration of support for action on climate change, and an inspiring reminder for people to take action on reducing their own carbon footprint.

Asking your energy supplier to upgrade you to a smart meter is an easy step to take towards protecting the planet. Smart meters show you how much gas and electricity you’re using in pounds and pence, giving you the information you need to make positive changes and reduce energy waste at home.

Smart Energy GB, the voice of Britain’s smart meter rollout, is encouraging people to sign up to a Twitter ‘Thunderclap’ to help make the 10th anniversary of Earth Hour count. The tweets will go out the day before Earth Hour, creating a tidal wave of reminders to go green and get a smart meter. Please sign up here and make sure your voice is heard.


Ian’s resolutions for making Earth Hour last all year 

  1. Be wise about warmth. I’m going to be more resourceful with heat this year – leaving the oven open as it cools, melting butter and defrosting bread in natural sunlight or on top of a radiator, and making use of steam generated from cooking. I’ve even been thinking about what I could cook in the natural warmth generated by my compost heap. 
  1. Cook smarter. This year I’m focusing on integrating lots of small energy saving tricks I’ve discovered with my smart meter, such as cooking pasta in pre-boiled water with the heat switched off, using pans with a bigger surface area, cooking whole meals in my slow cooker, and whipping up cakes and bakes in the microwave. 
  1. Mind your miles. I’m a travel photographer so it’s important I plan trips carefully to minimise air miles, and I use my bike or my own two feet as much as I can. This year, I’m going to buy more second hand clothes as the production and transport of goods has a high carbon impact. 
  1. Reduce waste. I think small habitual changes are most impactful, so I’m trying to knock a minute or two off my shower time, avoid leaving things on standby, update to LED light bulbs as the old ones run out, and use an electric blanket in the bedroom instead of a fan heater. 
  1. Be resourceful. Creativity is key when it comes to making positive changes, and enjoying the great outdoors is a good place to start. This year I’m going to experiment with some outdoor cooking methods, as well as continuing to dry clothes outside and growing my own vegetables when I can.


Ian’s energy saving mojito cake   

To enjoy during Earth Hour itself, Ian has developed a green-themed mojito microwave cake, which is the latest mouth-watering treat in his ongoing series of energy saving recipes.

The cake has an energy cost of 2p, and takes just two minutes to make in the microwave. The recipe can be found here.

Ian has used his smart meter to help him accurately test which cooking methods and techniques use the least energy and to give every one of his energy saving recipes its own energy cost. This new energy saving microwave cake is the perfect planet-friendly treat!


Ian Cumming said:

“I’ve always tried to be eco-friendly, but sometimes you need some visibility around your lifestyle patterns, and some inspiration to get started. When I upgraded to a smart meter last year – which shows me how much energy I’m using and how much it’s costing – it was a total revelation for my whole family.

“I’ve pledged to make my Earth Hour last all year, using information from my smart meter as inspiration, and hope to encourage others to do the same. I hope people enjoy making my energy saving mojito cake, as a fun and tasty way to save energy.”


Fflur Lawton, Head of Policy and Communications Wales at Smart Energy GB, said:

“Ian’s resolutions for Earth Hour are really imaginative and I’m thrilled that his smart meter has helped to inspire and inform him along the way. I’ll definitely be trying the energy saving mojito cake at home.

“More than eight in ten people with smart meters have taken steps to reduce energy use, so Earth Hour is a great opportunity to contact your supplier about arranging your upgrade.

“Smart meters lay the foundation for smarter energy grids, as well as being a unique platform for innovation across the industry. Embracing digital technology means we can all look towards a cleaner, greener Great Britain, with an efficient and intelligent energy system, and a reduction in CO2 emissions.”


Anne Meikle, Head of WWFCymru, said:

“Our Earth Hour campaign is all about encouraging action on tackling climate change.

“Across Great Britain, smart meters are already encouraging millions of unnecessary lights and screens to be switched off, and more thermostats to be kept in check. Requesting a smart meter from your energy supplier is a great step you can take towards reducing your carbon footprint.”

Mae wedi dyfeisio rhai addewidion hawdd y gellir rhoi cynnig arnynt gartref i annog eraill i wneud yr un peth gan ddefnyddio adborth o’i fesurydd clyfar fel ysbrydoliaeth, ac mae wedi datblygu rysáit gwyrdd sy’n arbed ynni hefyd gyda chymorth ei fesurydd clyfar.

O fod yn arloesol gyda ffynonellau gwres naturiol i ddefnyddio ei fesurydd clyfar i leihau gwastraff ynni, mae addewidion Awr Daear Ian yn dangos bod mynd yn glyfar am newid yn yr hinsawdd yn dechrau gartref gyda newidiadau bach meddylgar.

Mae’r Awr Daear yn arddangosiad mwyaf y byd o gefnogaeth dros weithredu ar newid yn yr hinsawdd, ac mae’n ffordd ysbrydoliaethus o atgoffa pobl i gymryd camau ar leihau eu hôl troed carbon eu hunain.

Mae gofyn i’ch cyflenwr ynni eich uwchraddio i fesurydd clyfar yn gam hwylus tuag at ddiogelu’r planed. Mae mesuryddion clyfar yn dangos i chi faint o nwy a thrydan rydych yn eu defnyddio mewn punnoedd a cheiniogau, gan ddarparu’r wybodaeth y mae ei hangen arnoch i wneud newidiadau cadarnhaol a lleihau gwastraff ynni gartref.

Mae Ynni Clyfar GB, llais ymgyrch cyflwyno mesuryddion clyfar Prydain, yn annog pobl i gofrestru ar gyfer ‘Taran’ ar Drydar i helpu gwneud i 10fed pen-blwydd yr Awr Daear gyfrif. Bydd y trydariadau’n mynd allan y diwrnod cyn yr Awr Daear, gan greu ton enfawr a fydd yn atgoffa pobl i fynd yn wyrdd a mynnu cael mesurydd clyfar. Cofrestrwch yma a gwnewch yn siŵr y cewch ddweud eich dweud.


Ymrwymiadau Ian ar gyfer gwneud i’r Awr Daear bara trwy gydol y flwyddyn 

  1. Byddwch yn ddoeth gyda gwres. Rwy’n mynd i fod yn fwy call gyda gwres eleni – gan adael y ffwrn yn agored wrth iddi oeri, toddi menyn a dadrewi bara mewn golau haul naturiol neu ar ben rheiddiadur, a defnyddio ager a gynhyrchir wrth goginio. Rwyf hyd yn oed wedi bod yn meddwl am beth y gallwn ei goginio yn y gwres naturiol a gynhyrchir gan fy nomen gompost. 
  1. Coginiwch yn glyfrach. Eleni rwy’n canolbwyntio ar integreiddio llawer o ddulliau arbed ynni bach rwyf wedi eu darganfod gyda fy mesurydd clyfar, fel coginio pasta mewn dŵr a ferwyd ymlaen llaw gyda’r gwres wedi ei ddiffodd, defnyddio padellau gyda mwy o arwynebedd, coginio prydau cyfan yn fy llestr araf a chreu teisennau a phobi yn y microdon. 
  1. Cofiwch y milltiroedd. Rwy’n ffotograffydd teithio felly mae’n bwysig fy mod yn cynllunio teithiau’n ofalus i isafu milltiroedd yn yr awyr, ac rwy’n defnyddio fy meic neu fy nau droed cymaint ag y gallaf. Eleni rwy’n mynd i brynu mwy o ddillad ail law gan fod cynhyrchu a chludo nwyddau’n cael effaith uchel ar garbon. 
  1. Isafwch wastraff. Rwy’n credu mai newidiadau bach mewn arfer yw’r rhai sy’n cael yr effaith fwyaf, felly rwy’n ceisio torri munud neu ddwy oddi ar yr amser yn y cawod, osgoi gadael pethau yn y modd parod, uwchraddio i oleuadau LED pan fydd y rhai hen yn methu, a defnyddio blanced drydan yn yr ystafell wely yn lle tân bach. 
  1. Byddwch yn ddyfeisgar. Mae creadigrwydd yn allweddol o ran gwneud newidiadau cadarnhaol, ac mae mwynhau’r awyr agored yn lle da i ddechrau. Eleni rwy’n mynd i arbrofi gyda dulliau coginio awyr agored, yn ogystal â pharhau i sychu dillad yn yr awyr agored a thyfu fy llysiau fy hun pryd bynnag y gallaf.


Teisen mojito arbed ynni gwyrdd Ian  

I’w mwynhau yn ystod yr Awr Daear ei hun, mae Ian wedi datblygu teisen mojito microdon â thema werdd, sy’n un o’r danteithion diweddaraf yn ei gyfres barhaus o ryseitiau arbed ynni.

Mae gan y deisen gost ynni o 1c, ac yn cymryd llai na dwy funud i’w wneud yn y microdon.

Mae Ian wedi defnyddio ei fesurydd clyfar i’w helpu profi’n gywir pa ddulliau a thechnegau coginio sy’n defnyddio’r ynni lleiaf ac i roi cost ynni i bob un o’i ryseitiau arbed ynni. Y deisen ficrodon werdd newydd yma yw’r danteithfwyd llesol i’r planed perffaith!


Meddai Ian Cumming:

“Rwyf bob amser wedi ceisio bod yn llesol i’r amgylchedd, ond weithiau mae angen gweladwyedd ar eich patrymau ffordd o fyw a rhywfaint o ysbrydoliaeth i gychwyn arni. Pan uwchraddiais i fesurydd clyfar y llynedd – sy’n dangos faint o ynni rwy’n ei ddefnyddio a faint mae’n ei gostio – roedd yn syndod llwyr i’m teulu i gyd.

“Rwyf wedi ymrwymo i wneud i fy Awr Daear bara trwy gydol y flwyddyn, gan ddefnyddio gwybodaeth o fy mesurydd clyfar fel ysbrydoliaeth, ac yn gobeithio annog pobl eraill i wneud yr un peth. Rwy’n gobeithio y bydd pobl yn mwynhau gwneud fy nheisen mojito arbed ynni gwyrdd fel ffordd flasus a llawn hwyl o arbed ynni.”


Meddai Fflur Lawton, Pennaeth Polisi a Chyfathrebu Cymru gydag Ynni Clyfar GB:

“Mae addewidion Ian ar gyfer yr Awr Daear yn hynod ysbrydoliaethus ac rwy’n hynod falch bod ei fesurydd clyfar wedi helpu i’w ysbrydoli a’i gyfeirio trwy gydol y daith. Byddaf yn rhoi cynnig ar y deisen mojito arbed ynni gwyrdd gartref yn bendant.

“Mae mwy nag wyth o bob deg o bobl sydd â mesuryddion clyfar wedi cymryd camau i leihau eu defnydd o ynni, felly mae’r Awr Daear yn gyfle gwych i gysylltu â’ch cyflenwr ynglŷn â threfnu’ch uwchraddiad.

“Mae mesuryddion clyfar yn gosod sylfaen ar gyfer gridiau ynni clyfrach yn ogystal â gweithredu fel llwyfan arloesedd unigryw ar draws y diwydiant. Mae cofleidio technoleg ddigidol yn golygu y gallwn i gyd edrych ymlaen at Brydain Fawr sy’n lanach ac yn wyrddach, gyda system ynni effeithlon a chlyfar, a gostyngiad mewn  allyriadau CO2.


Meddai Anne Meikle, Pennaeth WWFCymru:

“Mae ein hymgyrch Awr Daear yn ymwneud ag annog gweithredu ar fynd i’r afael â newid yn yr hinsawdd.

“Ledled Prydain Fawr, mae mesuryddion clyfar eisoes yn annog pobl i ddiffodd miliynau o oleuadau diangen ac i gadw llygad ar y thermostat. Mae gofyn am fesurydd clyfar gan eich cyflenwr ynni yn gam pwysig y gallwch ei gymryd tuag at leihau eich ôl troed carbon.”[:]
