In Jämtland County, a sparely populated and densely wooded are in central Sweden, more than 60% of all heat and power is derived from renewable sources. The county’s aim is to become a 100% non-fossil fuel region by 2015. This ambitious target can be reached this thanks to immense natural resources, notably woods and forests covering 99% of the Jämtland’s territory and being an extraordinary source of biomass.

Magnificent views over the lake and the mountains inhabited by bear and moose. 00:00:00
A panorama typical of Jämtland County, a large and extremely sparsely populated area in the centre of Sweden. 00:00:07
For centuries this far away and mysterious region has fascinated scientists and local people alike. 00:00:14
The Great Lakes, Dorset, is seemingly calm and peaceful, 00:00:20
but according to hundreds of eyewitnesses a huge snake-like monster lives in its blue and black depths. 00:00:24
Of course there's never been any hard evidence to prove the existence of this local Loch Ness monster, 00:00:30
but the region is remarkable for other reasons, notably for its impressive use of renewable energies. 00:00:35
We're in Östersund, Jämtland's only city located on the shores of the lake. 00:00:42
Since the period of the Vikings, Östersund has remained the only urban centre and hub of social life in this huge rural area. 00:00:54
Despite ice-cold winds, most of the city's households and buildings are warm, thanks to the local district heating system. 00:01:01
90% of the city's heat and some 30% of its energy use is produced here, 00:01:11
in Östersund's combined heat and power plant, exclusively fuelled by biomass. 00:01:17
The mountains of wood residues accumulated during the short northern summer are used to fuel the plant during the long and cold winters. 00:01:22
To generate heat and power, the plant's steam boilers burn all kinds of wooden material. 00:01:30
Wood chips, bark or sawdust from the local forestry industry, or even doors and shutters from demolition works. 00:01:35
Today, the total use of heat and power derived from renewable sources amounts to more than 60%. 00:01:45
But the county's aim is far more ambitious, to reach 100% use of renewable energy by 2015. 00:01:52
This target is possible thanks to the densely wooded landscape, which covers 99% of the county's territory. 00:02:00
Wood and forests are an extraordinary source of biomass. 00:02:06
This organic biofuel has huge potential, and its use is strongly encouraged by the European Commission. 00:02:10
I expect that the use of biomass in producing heating and cooling, producing power, is still immense, 00:02:16
because it really grows in Europe. It's our internal resource, so we are not dependent on this resource from somebody else. 00:02:24
At the same time, it's economically and financially viable, and it can be used already by existing technologies. 00:02:31
Of course, the aim is to persuade the consumers to convert from fossil fuels to biomass technologies. 00:02:40
We have done very many information activities for both common people, with information in the evenings, 00:02:47
in different places in the county, speaking about how to use biofuels, how big the investments are, 00:02:56
how you install them and so on, also with district heating and heat pumps. 00:03:03
Jimmy Annual of the county's energy agency promotes biofuels in Jämtland's eight municipalities. 00:03:10
Apart from alternative heating solutions, his aim is also to encourage the use of alternative cars, 00:03:17
running on clean and cheaper bioethanol. 00:03:23
If we talk about household heating, we know that in three or four years we'll be using zero fossil fuels for heating. 00:03:27
But if we talk about cars, it'll take longer. 00:03:36
The goal is to use bioenergy for cars, but that will still take some time. 00:03:45
Karl-Erik Strindlund has always been open to sustainable energy solutions. 00:03:52
In 2003, he converted his heating from electricity to biomass. 00:03:56
Hot water pipes buried in his garden supply heat, produced in the Östersund plant, directly to his house. 00:04:01
Well, here is the whole installation for the district heating. 00:04:08
I mean, with the heat exchanger, the heat pump, the heating system, 00:04:13
I mean, with the heat exchanging units, and here is a small computer. 00:04:19
Even though winter temperatures in Jämtland can easily reach minus 30 to 40 degrees Celsius, 00:04:33
the Strindlund family is not afraid of high winter heating costs. 00:04:38
The new installation helped them lower their energy bills, 00:04:42
and have safe, comfortable and environmentally friendly heating. 00:04:45
A decision which they considered carefully. 00:04:48
It is so that in some years, in 10, 20, 30 years, there will be lack of oil, 00:04:50
and we have the global warming problem, 00:04:58
and at the same time, here in our county, we are living in the middle of forests. 00:05:01
We have lots of biofuel growing around us. 00:05:08
So we have to use these local resources. 00:05:11
While such large-scale heating distribution is available only for Östersund and its surroundings, 00:05:16
similar small-scale solutions have been applied in villages across Jämtland. 00:05:22
This is the case for the village of Brunflö, 00:05:26
which recently converted from oil-generated heating to wooden pellets, 00:05:29
and now supplies heat and hot water to some 700 households. 00:05:33
Produced by local timber companies, 00:05:38
the pellets are becoming an increasingly popular clean heating solution in Jämtland county, 00:05:40
as well as in the whole of Sweden. 00:05:44
Burning pellets releases as much carbon dioxide 00:05:46
as if the wood had been left to break down naturally in the forest. 00:05:49
The pellets are produced from discarded wood chips and sawdust 00:05:52
that would otherwise be thrown out, 00:05:56
so no additional trees were cut down to produce them. 00:05:58
The new pellet boiler now heats the house of Katrin Johansson. 00:06:02
Dried and compressed, 00:06:06
wood pellets are significantly more efficient at producing heat than plain wood. 00:06:08
In the summer, Katrin fills up her boiler once a week, 00:06:12
and once a day in winter. 00:06:15
Before we had a heating system, 00:06:21
we used to heat the wood pellets in the summer. 00:06:24
Before we had a heating system that used wood. 00:06:28
It was tiresome to go down all the time to put the wood in the boiler, 00:06:32
and that's why we changed to pellets, 00:06:36
so we don't have to put things into it so often. 00:06:39
Despite the quite large investment for a pellet boiler, 00:06:45
Katrin feels it's well worth it, 00:06:48
since it's much more comfortable and it pays off in the long run. 00:06:50
Her environmentally friendly boiler provides hot water 00:06:53
and keeps the whole house warm, 00:06:56
all with the pleasant smell of burning wood. 00:06:58
With its 100% renewable energy supply project, 00:07:04
Yampland County has recently become one of the first partners 00:07:07
in the EU's new four-year campaign, Sustainable Energy Europe. 00:07:10
The main motivation was to share its biomass experience 00:07:15
and to see how the sustainable energy is used 00:07:18
in other European regions and communities. 00:07:21
Most of all, we want to show other regions in Europe 00:07:24
how we use biofuels, both for heating directly in houses 00:07:27
and district heating and for power production. 00:07:32
And of course, we also want to get experiences from other energy agencies, 00:07:35
how they work concerning, for example, solar energy and so on. 00:07:39
Disseminating best practices and exchanging experiences 00:07:43
on new markets, technologies and employment opportunities, 00:07:46
that's the role of the partners involved in this EU campaign, 00:07:49
promoting sustainable energies. 00:07:53
In a lot of European communities, 00:07:55
there have been fantastic projects going on. 00:07:58
A lot of companies are doing an excellent job. 00:08:00
So we need partners to bring this knowledge to other Europeans, 00:08:03
because only in this way we can be really strong, 00:08:08
we can be environmentally friendly 00:08:11
and Europe will continue to be a prosperous region. 00:08:14
Jämflens County's sustainable energy capital 00:08:18
is mainly based on the biomass growing all around. 00:08:21
But all European regions have in fact potential 00:08:24
to develop a wide range of clean energy solutions. 00:08:27
Many of them are already striving to adopt 00:08:30
a sustainable energy pattern of development, 00:08:32
so contributing to a cleaner and more prosperous world. 00:08:35
