reportOur stay in Denmark passed in two stages (since from here we flew to Iceland), and in two places mainly: Jutland, the area where the Folkecenter is, and Copenhagen.Two very different places. One,reserved, immersed in the rural life, and which survives by making use of nature´s resources; the other, urban, more overt and where the presence of the industry is patent. Such differences seem to cause antipathy to each other. As they commented to us in Copenhagen, in the capital they are not very fond of the Jutlanders The disparity between capital and provinces that is well known everywhere.On this subject we think that the policy, affected by the latest
international events, has something to do with this matter. In
Denmark the conservative right wing, Jutland being the base of
their support,won the last elections. Leaving the controversies to one side, we must say that we are
pleasantly surprised with the welcome in Jutland. We needed to
connect to Internet, and we stopped in a little village; where,
after passing by the information bureau, they sent us to the school!
Still surprised, we saw ourselves within the scholastic enclosure
surrounded by children who were playing rolling on the ground…
and without even asking any questions, they let us use the computers
of the library next to the children. Small towns and dispersed farms are scattered around the impressive
landscape of these rural surroundings. Located in the west coast
of the country, it receives the visit of a multitude of Germans
tourists who go to camp sites (impeccable) along these coasts.
It is a rich and fertile land and apparently they live quite comfortably
here, in this peacefulness. And when we speak of European tranquillity,
we mean total calm and tranquillity. We did what the young people want to do, we left Jutland and went
to Copenhagen, intending to spend a couple of days before flying
towards Iceland. Once installed, in an immigrant area, we went to look around the
capital. To take a walk in this city, full of bicycles and beautiful
people is our first recommendation. The lakes, birds, green spaces,
sculptures, the famous "Little Mermaid"… and the
famous attacks that she receives. And it is because of the latest
of these attacks that we could not see the sculpture. A couple
of days before our arrival in the capital the "Little Mermaid"
underwent another aggression, somebody had put an explosive device
under her. It is surprising but nobody looked too indignant, and
it means that it is normal to have the sculpture in the "factory"
for restoration, since in the last years it has undergone several
attacks. Danish people like to look after their surroundings, but they have
a big problem in this matter -apart from the reticence that their
Government shows in these matters – and that is the proximity
of a nuclear power station. Returning to the capital, on one of our walks we paid attention
to the kiosks and we realized that in the majority of publications
there was a great coverage of the royal family (newspapers and
sensationalist press) It is not surprising that Christiania was the chapter that caused
most interest to us in our visit to Copenhagen, for the international
fame of this district. Thanks to Balder we got to know it more
closely. The history of Christiania is full of conflicts with the authorities. The number of times the City council of Copenhagen and of the Central Government have tried to make Christiania disappear are innumerable. Prohibitions,a thousand laws,military occupation… of everything have been suffered by those that wanted and want to live their own way. Only for that reason: they don’t want to pass through the mesh imposed by the authorities and their model of society. Everything has been used against them, but above all the subject
of drugs. In Christiania marijuana is legal,many stalls can be
found where it can be bought. While the government maintains that
it is a den of dealers, their inhabitants carry out a campaign
against hard drugs. This has always been the attitude of Christiania
as opposed to the harassment of the authorities: imagination;
in any format: plastic music, arts… After Copenhagen and 10 fantastic days in Iceland, we returned to the FolkeCenter, where they were keeping our van and the caravan. Although this time it would not be for continuing discovering new places, but to study all the compiled information and to put ourselves fully into the work. Among other things this report that we are offering you here:
ekogaia projectDenmark has been without a doubt a pioneering country in terms of renewable energies at a European level. Among all the renewable sources that they use at different levels, is the Aeolian one which is by far the one most widely used. In fact, 21% of the electrical consumption that nowadays Denmark demands is generated by these mills, which are scattered all over the country. And according to the plans anticipated by the government this contribution will be of 50% in the year 2030. We had the opportunity to see a practical case of clean electricity
local production by means of the wind in the lands of Sydthy.
Here, in a region in which 12,000 people live and 75 MW of electrical
energy is consumed, thanks to the 145 installed mills they get
130 MW, much more than they will use. This power surplus is sold
to the national network to be distributed to other users. This
way they are soon able to pay off the investment made in the installation
of the mills. At first, when Denmark began to work with the Aeolic energy, the government subsidized 30% of the cost. The subsidies were lowered as the mills increased in number and capacity, until in 1988 the aids stopped. So nowadays public aid for their installation does not exist. Most of the Aeolic generators of this area oscillate between powers of 200-500 KW, and can produce between 500,000 and million KW/h/year, depending on its power. Therefore, if a mill of 200 KW of power costs about 180,000 euros, and considering its annual production, the average term of repayment of the initial investment comes out as 6 years. Later, all is through revenue. You would think that, with so many windmills in such a small country as Denmark, the landscape would be disfigured. It is true that there are a multitude of mills of all types and colours, but at no moment did they gave us the sensation of being "extra natural" elements in these surroundings. In fact, they are usually well integrated into the landscape, without negative consequences. Moreover, in some cases they have given a special aspect to those places in which they have been placed, for example the famous mills in a row along the coast of Copenhagen, so often portrayed in the postcards. You will be able to find more information on this and other subjects about Aeolic energy in www.windpower.org, a very well worked website that you will find very pleasant and didactic. But in addition to the wind it is not difficult to see the use
of other power sources, for example, taking a walk in the streets
of Copenhagen, we verified by the multitude of dishes installed
on balconies and facades of the buildings,the fact that solar
energy is quite popular. The FolkeCenter (house for the people) has been one of the main reasons for coming to Denmark. During the last few days we have had the opportunity there to meet people of diverse places who work in different areas of renewable energy. Among them the president of the world-wide association of Aeolian energy (WWEA) Preben Maegaard, as well as his homonym in the Wave Energy Association, Stig Vindelav. Regarding learning, without a doubt the days spent in the centre have been the most productive ones of the trip. Wave energy, Aeolian energy, solar power, biogas, biomass, the varied uses of the pure plant oil, bio construction, solutions for residual waters… it is incredible what it is possible to see and to learn in the facilities of the FolkeCenter. The centre has been invaluable to us in making contacts. We met Ibrahim Togola, for example, the person in charge of the Mali FolkeCenter,who after a pleasant exhibition of the activities of their centre, invited us to collaborate with them in the future. It is not surprising then,that the work of the Folkecenter, which appeals to many people from all over the world who wish to learn and to widen their knowledge of the Renewable ones, is an advantage because of its vast experience. The folkecenter, is an independent non-profit making institution,
managed by a Board. Funding is from the Danish Government plus
project funding. It has 3.000 square metres including offices,
workshops, exhibitions, training centre, etc. Folkecenter works on four major fronts:
We really wish to thank them for the tremendous welcome and hospitality we received,for the possibility that we had to use facilities that were essential to us for work, and, to thank Jane, Niels, Raghavan, Preben, Stig, Ibrahim, and all the rest,for the wisdom that they have shared with us. To all of them, thank you very much. ***Except for the part of the bio construction in Copenhagen, all the following experiences have been guided and/or recommended by the people in charge of the FolkeCenter.
Nowadays, of its size, it is the oldest Aeolian generator in operation in the world. They have spent 28 years since in 1975 the idea of constructing the generator was born amongst a group of teachers of the Tvind School. With the construction of an Aeolian generator that produced clean energy and that would end up becoming the standard of its fight; they wanted to put the practical counterpoint to a form of energy generation that they considered a threat to nature, such as the nuclear one. In those years Denmark was submerged in a great controversy because of the intention of its government to install one that would be it’s first nuclear power station. They had two objectives; on the one hand to cover the necessities of the school and their surroundings with ecological energy and on the other hand, to demonstrate to the world that clean and productive ways exist to obtain energy instead of the nuclear one. So that, with the aid of students and volunteers, the work began. Time went by and the project was gaining fame and hundreds of people volunteered their help. It is estimated that around 100,000 people interested in this extraordinary project, got to visit the place during it’s construction. Thus, after two years of arduous work of hundreds of volunteers, they were able to raise the one that in its day would be the greatest Aeolian generator in the world, a windmill of 54 meters. But their great deed did not finish there, since with its participation in the debate against the nuclear power plants they achieved an agreement that no power station of this type would be allowed in Denmark. Nowadays Denmark is a country that does not have nuclear power stations. Teachers totally financed the project, with a cost around a million euros. In spite of being finished by the year 1977 it would not be put into operation until 1978. This mill generates 900 KW of electrical power that is used for the consumption of all the school’s facilities; the remaining energy is sold to cover other economic necessities. It is fantastic and surprising to verify how by means of communitarian
work, known so well in our land, and with the voluntary aid of
people, the construction of a nuclear power station could be avoided
using an ecological system that still today supplies power- and
economically- to the whole school complex. It is necessary to
say that the initial investment has been more than repaid. Therefore,
in addition to being a system which respects the environment,
it had, and has, a way of covering its economic necessities that
still lasts. An absolutely excellent example.
The Wave Dragoon is an invention that produces electrical energy from the waves of the sea located just 5 minutes from the FolkeCenter. This construction, which in its totality reaches 250 meters, is composed of two wings or arms of 126 meters that channel the force of the waves towards the central body, constructed in steel of 8 mm of thickness; weighs more than 150 tons, to which there are added other 87 tons of weight from the water and thus to obtain the ideal weight so that the platform can work. In spite of the impressiveness, it works very simply. The waves are directed towards to the central body by means of the arms of the platform, the gathered water will rotate the installed turbines. It is the rotation of the turbines that generates the electricity. The location of the plant, its size and its capacity will depend on the circumstances and the force of the waves in each place. The people in charge of this installation have a connection to Internet that allows them at any time to consult the production and the statistics, for the complete following of the work of this prototype. The Wave Dragoon is the project most subsidised by the government,
within its policy of support to the emergent Wave energy, to the
detriment of the aids to the Aeolian energy, which is much more
developed. Although it seems incredible, all the energy consumed in the form of electricity, heating, including installation for the land, comes from pig manure (that creates so many problems in our soils), by means of a system of recycling based on biogas. It is a very simple system. Manure is stored in a silo specifically
prepared, and is dried there, approximately 3 weeks. Biogas can cover without any problem all the necessities for which nowadays we use "natural gas". On the journey to this farm we visited another potential example of biogas. In concrete two generators of electricity and 750 hot water of KW/h each one. Although today they work by means of natural gas, they will be fed with biogas in the near future. It’s a complex and impeccable infrastructure of constructed canalisation to be able to provide the hot water to the dispersed 270 houses of the area. The power cycle of the PPO is the following one: After harvesting (sunflower, rapeseed, jathropa…) the seeds are pressed; also seaweed can be used. From the pressed seed, oil and cake are obtained. This last one is used as food for the animals or as installation depending on the used plant. Once filtered, the obtained oil is, normally suitable for human consumption. This oil can be used as fuel for heating, and in all types of transport vehicles, cars or trains, tractors and boats, once a simple kit has been installed in its engine. Advantages of using vegetal oil as fuel:
Nowadays the vegetal oil used as fuel for transport is not subsidized. What’s more, it’s charged with taxes that increase considerably its price . This affects the consumers who use vegetal oil as fuel, who are awaiting the reform of the legislation of the EU in this matter, since supposedly this tax will disappear. However, the use of this oil for heating does not pay taxes. So
that it is this last option that is most used in Denmark as far
as the consumption of this fuel. We verified it on Jens Builders
farm, which produces a great amount of oil and fodder. He uses
the oil for the heating but not for his vehicles; as he has to
pay taxes to use it, it’s cheaper to buy diesel oil; so
that he sells most of the product, for example to the FolkeCenter. The eco-village in Hjortshoj was established in 1986. It has developed from a 10-family-home society to one with 76 private houses today (and one common one), and is looking for 100 more in the near future. Before the building started hundreds of people were interested in this idea, but only a few families took the initiative and built the first houses. They used clay and recycled paper (for insulation) to construct the buildings. They intensely discussed what kind of energy to use to make it as environmentally friendly as possible. So they decided to build the local heating system, which uses wood. They use fast-growing willow trees on a plot that is also used to purify the grey waters from the village. Actually, they introduced almost everything "green”, which is possible: use of rainwater, dry toilets, solar architecture patterns, wood as one of the main building materials, and waste-recycling systems. Today almost everything works well, but many of their objectives
have yet to be reached. When fully-established, the community
will consist of about 500 people on an area large enough to ensure
self-sufficiency.
Balder has been working in bio-construction for 20 years. He has developed his work in different coops and actually he is member of the cooperative Logik&Co -- -Cooperatives and bio-construction. What they are, how they work. In the cooperatives the workers have the production means, and together (in community) they are looking for a way to make and to distribute the work. In bio-construction, it is constructed so that the house needs as few resources as possible, in shape of heating, electricity and water, and emits the minimum possible residues . When they are chosen, the construction equipments are picked which implies less cost of energy, its life span and the possibility of recycling . --Application of renewable energies in bio-construction --Your stay in Christiania.
