NEARLY TWO-THIRDS OF THE WORLD’S ENERGY IS CONSUMED IN CITIES. THEY GENERATE OVER 70% OF THE WORLD’S GREENHOUSE GAS EMISSIONS BUT, IDEALLY, CITIES CAN ALSO LEAD THE WAY WHEN IT COMES TO THE CIRCULAR ECONOMY AND CLIMATE SOLUTIONS. » p. 8

How to prepare for an extended power outage:

✓✓ Get a torch and batteries or a candle and matches as a light source.

✓✓ You will need a battery-pow ered radio to listen to news and- announcements by the authorities. You can use the radio in your car, but phones will stop working when their base stations go offline.

✓✓ Chop up firewood for heating if you have a fireplace in your home.

HOW IRRESPONSIBLE IS IT...

...to leave your charger plugged in 24/7? It is irresponsible. The maximum power consump- tion allowed for chargers in standby mode is 150 mW. A charger left plugged in without a phone would waste 1.2 kWh of energy each year, and the estimated 6,000,000 chargers in Finland would consume a combined 7,200,000 kWh. That would correspond to the total annual energy consumption of 3,600 apartments. Do environmentally conscious thing and unplug your charger after use. PHOTO: MIKKO HIRVONEN MIKKO PHOTO:

#carbonneutral2035 Helen has set a target of carbon neutral energy production in 2035. We will achieve this goal step by step — first by stopping the use of coal, increasing use of renewable energy, and by building heat pumps and energy storage systems, for example.

Work sites cause changes to our familiar paths and routes. To promote road safety, Helen hired a work site cyclist for summer 2019 to help test and develop the traffic arrange- ments at work sites and com- municate exceptional routes. Spending the summer on a bike gave work site cyclist Aleksi Pippuri a whole new perspective on getting around the city. “I live in the city, so work sites have always been part of the picture, but I hadn’t paid much attention to them before. This job gave me the opportunity to really get to know them and help make them better. I hope my role has made people see that work sites are not an inconve- nience, but rather a necessary good.” As he surveyed the work sites, Pippuri noted that a psychological perspective is necessary for making effec- tive traffic arrangements. While traffic around work sites is always arranged with safety as the first priority, people will only follow the prepared routes if they are natural and convenient to use. “People move like water: they follow the path of least resistance. Those in charge of traffic arrangements at work sites need to think about how to create routes that people will actually use instead of taking dangerous shortcuts across the street, for example.”

3/2019 17 ME & MY HOMETOWN Holiday in Helsinki Staycationer Vera Melleri enjoys experiencing her hometown through the eyes of a tourist.

I found out about staycations when my chil- dren were still young. Travelling for a hobby of mine, I had realised how nice it was to spend some time alone in a hotel room. At first, it felt extravagant to get a hotel room in your hometown, but now I enjoy it to the full. I take a little time off for myself 2–3 times a year by putting together 24 hours of pampering around one night in a hotel. “I prefer places A staycation is an eco-friendly choice with personality,” says Vera Melleri because it doesn’t involve travel. at the Kaisaniemi I prefer places with personality.

You experience Helsinki differently when you’re on vacation. In the hustle of daily life, you don’t have time to wander off into side streets, get lost and visit cute little cafés. A staycation is all about taking it slow and not following a tight schedule. Having a lie-down is definitely part of my staycation rituals. I have a million things to take care of at home, so I really enjoy being able to just stretch out for a bit. I often treat myself to slightly overpriced chocolate truf- fles or other delicacies. You have to give time to yourself just like you give time to your family and employer. Instead of complaining about the hardships of daily life, you need to think about what you can do to make things easier on your- self. I like to look for hotel discounts. When a good one comes along, I come up with a plan for being a tourist in my hometown for that d ay. ”

3/2019 19 THE BIG PICTURE

The most densely populated city The Philippine capital Manila has grown around the Pasig River.

According to the latest sta- tistics, Manila has 1,780,000 people living in an area of 42.88 km², which gives it a population density of 41,500 people per km². It is the world’s most densely pop- ulated city. By comparison, Helsinki has 650,000 people living in an area of 215.16 km², which makes the popula- tion density just over 3,000 per km². Manila is part of Mega Manila, which already has more than 20 million people. This figure is expected to reach 30 million by 2030. Traffic congestion, air pollu- tion and hazardous living con- ditions are among its major problems. The response to these issues involves building several population centres of various sizes, with good cross traffic between them. This would prevent the population from accumulating around a single centre.

3/2019 23 ECO-ACTION Making the city greener The roof of a distribution substation in Punavuori was transformed into a pollina- tion station for the summer.

There’s a buzz in the air in central Helsinki on this bright summer morning. Bees and bumblebees fly from flower to flower, sipping nectar to pro- vide nutrition for their hives. “They won’t sting you,” say Eija Leinonen and Kaisa Viitanen. They are members of Make Punavuori Blossom, a commu- nity that waters the flowering plants at the pollination sta- tion built on the roof of a local distribution substation. The pollination station con- sists of flowering plants and plywood art. “The artwork features shapes inspired by the spe- cies of moss growing on the concrete walls of the sub- station. The shape of the art piece as a whole is triangular like the roof of the substation, so it combines natural and man-made shapes,” says art- ist-designer Päivi Raivio from the RaivioBumann Art and Design Studio. She created the piece in collaboration with Daniel Bumann. The station is a pilot for the Green Infra concept developed by the pair. “We chose pollinator-friend- ly­ plants, such as marigold, starflower and runner bean.” When the pollination station is taken down in late August, the plant boxes will be distrib- uted to make yards around Punavuori greener.

DID YOU KNOW? Helen partners with RaivioBumann on the Green Infra concept, which is aimed at making urban infrastruc- ture — such as roofs, vacant areas and underground spaces — greener.

24 3/2019 Green Infra projects are also planned for the roofs of the oil tanks at the Munkkisaari district heating station as well as the Sähkötalo rooftop terrace, which is earmarked EVENTS for a herb garden. The following cus- tomer events are scheduled for this autumn at Helen’s Energy Gallery on the third floor of Säh- kötalo at Kampinkuja 2 (Malminrinne 6), Helsinki. Coffee will be served starting from 4 p.m. Welcome! Registration: helen.fi/ tapahtumat
