CLEANTECH – ENERGY AND ENVIRONMENTAL TECHNOLOGY Like a glowing focal point, the question of how we should use our energy resources has gained an unquestioned place on the political agenda. CleanTech covers energy and environment- related development aimed at reducing consumption of natural resources. CleanTech is found in the sectors of energy, transport, agriculture, air and water quality. CleanTech companies work with energy, water treatment, waste management and materials recycling. Energy is the main component of CleanTech and the focus of this presentation. SWEDISH KNOW-HOW Preeminent Swedish technological development of renewable energy has garnered international attention. Investors in CleanTech are looking at Sweden, where long- term environmental research and technology development are the foundations of innovative energy technologies – and where the know-how required to efficiently integrate the technologies into society can be found. Decades of experience with goal-oriented, long-term initiatives have created expertise, experience and extraordinary networks. Unlike many other countries, the Swedish energy research programme has been distinctly oriented towards renewable energy and improved energy efficiency for a very long time. National political mechanisms, financial support for entrepreneurship, R&D and commitment to sustainable environmental policy are a few of the explanations. But the open and accepted climate of cooperation among industry organisations, politicians and scientists is another key contributor to Sweden’s considerable expertise in CleanTech RESEARCH AND DEVELOPMENT IN SWEDEN Sweden is one of the countries in the world that invests the most per capita in research and development. CleanTech research is no exception. Sweden has been making long-term investments in renewable energy research and technological development since the oil crisis of the 1970s. Sweden has also made tremendous progress in energy efficiency, especially in the industrial sector. The unmistakable focus has helped make Sweden a world-leader in many energy and environment-related fields. Renewable sources of energy account for 37% of Sweden’s energy supply. HEAT PUMPS Geothermal heat is actually pure solar energy, and the principle is basically very simple. The technology is based on utilising the solar energy stored in the ground during the year. Even climates without a lot of sun suffice to store enough heat energy underground. A fluid-filled house is heated underground and collects the stored heat of the sun. After that, the heat pump’s job is to concentrate the stored heat energy so that it can heat water in the house – in the tap and the shower as well as radiators. Heat pumps run on electricity, but the pump returns several times more heat energy than it uses. WHY ARE HEAT PUMPS A GOOD IDEA? • It takes only one part electricity to produce three parts heat • New technology yields hotter water and faster heat for less money • Geothermal heat reduces annual electricity consumption by 50 to 75% compared to other types of heating • Remote monitoring and control can be managed over the Internet • The heat pump can serve as a climate control system and be used for both heating and air conditioning DISTRICT HEATING District heating is usually highly resource- efficient and eco-friendly. A central district heating plant heats water, which is transported in a pipeline under high pressure to a district heating system in each building. Heat exchangers in the building use the hot water to heat radiators and hot water tanks. District heating provides 12% of all heating in Sweden. District heating plants can be run on a wide variety of fuel types and take advantage of energy that would otherwise go to waste, such as waste heat from industrial processes, forestry waste and energy recovered from rubbish and waste. Large-scale combustion yields high environmental performance and district heating is very reliable. District heating can generate both heat and power. WHY IS DISTRICT HEATING A GOOD IDEA? •District heating is usually a resource-efficient alternative that utilises a wide variety of fuel types and takes advantage of energy that would otherwise go to waste. Running heating plants with renewable fuels (instead of fossil fuels) is a major and important environmental transition. • Efficient use of surplus industrial heat • Flexibility and options in fuel choice • Enables energy recovery from rubbish and residual waste • Cost-effective heating in towns and cities • Flue gas purification at a single site reduces environmental impact • Reduced carbon dioxide emissions improves air quality in towns and cities • Efficient use of resources through co-generation of heat and power • Extremely reliable DISTRICT COOLING District cooling is based on the same principles as district heating. Water is chilled and then distributed in a pipeline to homes, offices, industrial buildings and other spaces that need air conditioning. The cold water is pumped around in a closed system and used to cool the air circulating in the building’s ventilation system. The same water is then piped back to the production facility to be rechilled. The temperature of the water pumped to buildings is about 6° C and the return water about 16°. The return water is heated as much as possible as rooms and processes are cooled. Sweden is benefiting from system expertise in district heating as well as the expansive technology infrastructure. WHY IS DISTRICT COOLING A GOOD IDEA? •District cooling provides a consistent and comfortable indoor climate year-round, while reducing energy use and carbon dioxide emissions. • Costs less than local cooling systems • Highly reliable • Consistently high comfort in commercial spaces and buildings • No noise from alternative cooling systems • Limited maintenance • No need to store or handle environmentally hazardous refrigerants and chemicals • Flexible adaptation for both comfort cooling and process cooling • Natural cold can be utilised in many cases, resulting in minimal energy consumption • District cooling and district heating production can be combined for more resource- efficient operation SOLAR ENERGY Sunlight can be used to produce heat or electricity. Solar cells (photovoltaics) are used to generate electricity. Silicon-based solar cells are currently the most widely used technology. There are metal contacts on both sides of the solar cell. When sunlight strikes the solar cell, a charge arises between the front and back sides. A solar cell produces a charge of about one half volt. The cell continues generating electricity as long as the light strikes it, but stops instantly in darkness. Solar cells are often assembled in solar modules that can be linked to produce higher voltage. WHY IS SOLAR ENERGY A GOOD IDEA? The sun’s energy is so abundant that once we have learned how to use it economically, energy supply will no longer be a problem. Sweden has been involved in developing various solar energy technologies for many years that can be successfully combined with other technologies. The results have been superb, since conditions vary from one environment to the next. For instance, there are now hybrid technologies that solve the problem of lighting in places where conventional infrastructure is unavailable, like forests, rural areas or mountainous areas. Integration of solar electricity and solar heating modules – a hybrid technoogy that supplies waste heat and enhances efficiency. Solar electricity and heat pump technology – a hybrid technology powerful enough to make single-family homes energy self-sufficient Solar cells, new battery technology and LED lighting – a hybrid technology for environments where there is no power line infrastructure. On-grid solar cells and solar heating systems connected to the district heating network – large hybrid systems that are a superb choice for heating in sunny countries. WIND POWER Wind power turbines utilise the energy in wind to generate power. Wind arises when the sun warms the atmosphere and creates temperature differences. This produces pressure differences that set air masses in motion. Modern wind turbines capture about one third of the power in the wind that passes through the rotor’s swept area. The blades on a wind turbine look something like a propeller and are linked to a generator that converts movement to energy. Wind is an almost infinite resource and creates no pollution. WHY IS WIND POWER A GOOD IDEA? •Wind power has many advantages from the environmental standpoint – the raw material is renewable and requires no permanent alterations to the environment. • Very limited environmental impact • Production causes no environmentally harmful emissions • There are no hazardous residual products and final storage is not required • There are no fuel costs involved in production • Production requires no transport of raw materials • A standard wind turbine produces more energy in less than six months than it took to manufacture it LED LIGHTING LED – Lighting Emitting Diode – is a young lighting technology that emerged in the 2000s, but is developing at warp speed. In another ten years or so, it is highly likely that most of our indoor and outdoor lighting will be powered by LED technology. LEDs can withstand major temperature variations, providing an enormous range of applications, since installations are not affected by the climate or the season LEDs are semiconductors that directly convert electric current to light. The diodes emit colored light – red, orange, yellow, green or blue. White light is created using a special LED technology and is becoming more common all the time. WHY IS LED LIGHTING A GOOD IDEA? •LED is an entirely new generation of lighting technology that is set to revolutionise the world in the next ten years. The technology has superior competitive advantages compared to low-energy light bulbs and incandescent bulbs. • LEDs have a lifetime of about 100,000 hours, which is a hundred times longer than a conventional light bulb. • The diodes are extremely energy efficient. About 50% of the energy in an LED is expended as light. In an ordinary light bulb, about 95% of the energy is expended as heat and only 5% as light. • LED lamps do not get as hot as halogen lamps. That makes LED lighting ideal for bookshelves and other cramped spaces that should not be allowed to overheat. • LEDs contain no environmentally hazardous substances like lead or mercury. CLEANTECH – AN INDUSTRY FOR THE FUTURE Interest in environmental innovations is rising steadily as global climate problems become more urgent. CleanTech is considered one of the most important industries of the future. The OECD estimates that the world environmental technology market will be worth about €644 billion in 2010. The European Commission has proposed targets to reduce emissions of greenhouse gases by at least 20% and increase the share of energy consumption from renewable sources to 20% by 2020, in accordance with the agreement made by EU Heads of State in March 2007. The relatively large percentage of renewable energy in the Swedish energy system is an outstanding achievement. About one fourth of Swedish consumption comes from renewable sources of energy. One example is the transport sector in Stockholm, where 25% of bus traffic in runs on ethanol or biogas. HEAT PUMPS HEAT PUMPS USE THE FREE ENERGY NATURE PROVIDES Geothermal heat is actually pure solar energy, and the principle is very simple. The technology is based on utilising the solar energy stored in the ground during the year. Even climates without a lot of sun suffice to store enough heat energy underground. A fluid-filled house is heated underground and collects the stored heat of the sun. After that, the heat pump’s job is to concentrate the stored heat energy so that it can heat water in the house – in the tap and the shower as well as radiators. Heat pumps run on electricity, but the pump returns two to four times more heat energy than it uses. SWEDISH GEOTHERMAL HEAT IS A FORCE TO BE RECKONED WITH We have tremendous experience with geothermal heat in Sweden and more heat pumps are installed here than anywhere else in the world. Thanks to all the residential and industrial installations, tried-and-true Swedish geothermal heat technology is ready for export. • Long-term research and development since the 1970s • Highly trained consultancies and certified installers • The large number of installations (500,000) has created a platform for independent researchers and developers • The Swedish Energy Agency in partnership with the SP Technical Research Institute of Sweden have carried out several independent tests of different heat pumps • Sweden has the highest number of installed geothermal heat pumps in the world GEOTHERMAL HEAT – A BRILLIANT, EFFICIENT IDEA Even climates without a lot of sun suffice to store enough heat energy underground. The heat pump can be used for both heating and air conditioning. • It takes only one part electricity to produce three parts heat • RPM control reduces energy consumption • New technology yields hotter water and faster heat for less money • Geothermal heat reduces annual electricity consumption by 50 to 75% • Remote monitoring and control can be managed over the Internet THE TREND IS STILL MOVING UP The fact that geothermal heat is financially advantageous has driven the installation rate for geothermal heat pumps in Sweden to new heights in the 2000s. A similar trend worldwide is highly likely. Today’s market, characterised by high prices for oil and electricity and carbon dioxide taxes, is favourable and is hastening the technical development of heat pumps. Mechanisms such as conversion grants and public/private partnerships have had a powerful impact on the positive development. Technology procurements have stimulated the development of new technology to get new products, systems and processes to market. The outcome of the 1994 technology procurement for heat pumps was an estimated potential savings of 5 to 6 TWh/year for the Nordic countries over 15 years. GEOTHERMAL HEAT IS REPLACING OIL The Johansson family of two adults and their teenage son live in a single-storey house with a basement in Torshälla, a small town in central Sweden. They heated their home with an electric oil and wood-fired boiler for 15 years. The house is 95 sq m, built of concrete with a wood facade. It took about 30 kWh/year to heat the house with the electric boiler. In spring 2005, the Johanssons installed a geothermal heat pump – and cut their electricity consumption in half. Now it takes only 14 kWh of electricity a year for heating and the Johanssons think their home has felt especially warm and cosy ever since. As an added bonus, the heat pump is much easier to maintain than the boiler.

The heat pump is especially eco-friendly when the electricity is produced using green methods like hydropower, wind power or biomass-fired co-generation. The fact that the heating principle is financially advantageous has driven the installation rate for geothermal heat pumps to new heights in the 2000s. Heat pumps collect both heat and cold from the soil, which is extremely useful in many countries with a warmer climate. This is also evident in the strong growth in the heat pump market in France, Germany and England. China has also begun using heat pumps. DISTRICT HEATING DISTRICT HEATING – A CLOSED SYSTEM THAT RECOVERS ENERGY District heating is a highly resource-efficient and eco-friendly source of heat. A central district heating plant heats water, which is transported in a pipeline under high pressure to a district heating system in each building. Heat exchangers in the building use the hot water to heat radiators and hot water tanks. DISTRICT HEATING – PRINCIPLE District heating plants utilise a wide variety of fuel types and take advantage of energy that would otherwise go to waste, such as waste heat from industrial processes, forestry waste and energy recovered from rubbish and waste. The technology is uncomplicated and very reliable. SWEDEN IS THE WORLD LEADER IN DISTRICT HEATING Sweden is the world leader in district heating. Consistent and relatively high environmental taxes on fossil fuels and openness to new solutions in the energy sector have driven technological progress and sharply reduced the use of fossil fuels. The transition from individual systems to large district heating plants has reduced emissions of nitric oxides, sulphur dioxide and particulates. Swedish carbon dioxide emissions have dropped by 20%. • A long history of building knowledge about how common systems should be built and maintained • Energy companies with tremendous financial endurance • Four-fifths of the heat used in Swedish district heating networks is based on energy that would otherwise have gone to waste SWEDISH DISTRICT HEATING FROM A GLOBAL PERSPECTIVE Swedish consultants have unique system expertise in relation to feasibility studies and planning district heating systems and are frequently called upon for projects run by organisations like European Bank and the World Bank. Several SWEHeat companies have been involved in recent years in the modernisation and expansion of district heating plants and networks in Eastern and Central Europe. Swedish experts have been used in North America for planning and operation of several district heating plants. China has used Swedish technology to manufacture insulated pipes and for a range of other district heating products. Swedish district heating technology is solidly established in Europe. DISTRICT HEATING – A RESOURCE-EFFICIENT ALTERNATIVE District heating utilises a wide variety of fuel types and takes advantage of energy that would otherwise go to waste. Running heating plants with renewable fuels is a major and important environmental transition. • Efficient use of surplus industrial heat • Flexibility and options in fuel choice • Enables energy recovery from rubbish and residual waste • Cost-effective heating in towns and cities • Flue gas purification at a single site reduces environmental impact • Reduced carbon dioxide emissions and cleaner air in towns and cities • Efficient use of resources through co-generation of heat and power • The technology is uncomplicated and extremely reliable STOCKHOLM – A GREEN LEADER AMONG WORLD CAPITALS District heating produces about 75% of the heat required to keep Stockholm warm. The high percentage has made Stockholm a green leader among world capitals. Stockholm is growing and district heating is growing right along with it. Högdalenverket is one of the biggest district heating plants in Europe. The household waste produced by the people of Stockholm is burned here and converted to electricity and district heating. Over the years, this has contributed to sharp reductions in emissions of carbon dioxide and other harmful substances. Every year, Högdalenverket takes in 500,000 tonnes of household waste and 200,000 tonnes of sorted industrial waste, which is converted to 450 GWh of electricity and 1,700 GWh of district heating for a quarter million Swedes. REFERENCE SITES District heating has been used in Sweden for more than fifty years, and today there are more than 200 district heating systems. They range in size, from the smallest, which sell about 5 GWh a year up to the biggest, which sell more than 7 TWh (7,000 GWh) a year.

International interest in district heating is rising fast and the potential benefit to the global climate may be enormous. Simply by doubling the use of district heating in Europe, the EU could meet its commitments under the Kyoto Protocol by a wide margin. Opportunities to expand CHP in Europe are particularly favourable. DISTRICT COOLING DISTRICT COOLING – A TECHNOLOGY WITH MINIMAL ENVIRONMENTAL IMPACT District cooling is based on the same principles as district heating. Water is chilled and then distributed in a pipeline to homes, offices, industrial buildings and other spaces that need air conditioning. The cold water is pumped around in a closed system and used to cool the air circulating in the building’s ventilation system. The same water is then piped back to the production facility to be rechilled. The cooling may even consist of natural cold taken from cold water layers deep in lakes, rivers or the ocean. Snow stockpiles saved from the winter can also be used in district cooling systems. See principle DISTRICT COOLING – PRINCIPLE SWEDEN IS A PIONEERING COUNTRY IN DISTRICT COOLING Sweden’s first district cooling plant went operational in 1992. Today, there are about thirty plants producing district cooling in Sweden. Studies show that total demand for district cooling equals about 2000-5000 GWh. District cooling replaces used to run individual air conditioners, which goes hand- in-hand with lower operating costs and better environmental performance. Swedish district cooling companies have laid a strong foundation for building systems in the form of pipelines. The district cooling companies are turnkey contractors who supply the entire heating and air conditioning requirement. THE SMART WAY TO PRODUCE COOLING District cooling provides a consistent and comfortable indoor climate year-round, while reducing energy use and carbon dioxide emissions. • Costs less than e.g. compressor-driven air conditioning • Highly reliable • Consistently high comfort in commercial spaces and buildings • No noise from alternative cooling systems • Limited maintenance • No need to store or handle environmentally hazardous refrigerants and chemicals • Flexible adaptation for both comfort cooling and process cooling DISTRICT COOLING IS MAKING STRIDES The growing numbers of computers in the workplace and the realisation that comfort cooling increases productivity have brought greater demands for a comfortable climate at work. As a result, the need for eco-friendly and cost- effective comfort solutions is increasing every year and the market is growing rapidly. • 10% of global electricity production is used for cooling • 16% of US electricity production is used for cooling • More than 80% of buildings in the US and Japan are air-conditioned. The figure is less than 50% elsewhere in the world, but is rising fast • The EU expects district cooling to provide 25% of the requirement by 2020 THE HEATING PLANT IS COOLING LINKÖPING The regional utility company, Tekniska Verken, supplies district cooling in two large networks in central Linköping. The absorption heat principle is used to produce the cooling in the large central plants that run on district heating. Technological progress has now made it also profitable to build small local networks with compact air conditioning systems that run on district heating. Tekniska Verken is now offering the solution to buildings that are not connected to the main district heating networks.

SOLAR ENERGY THE SUN – THE CLEANEST ENERGY SOURCE The sun is a clean source of energy. Solar energy emits no toxic emissions or hazardous waste and demands no energy to produce energy. Solar energy can be used to generate both heat and electricity. The easiest way to generate solar heating is to let the sun heat water in a solar collector. THE SUN – THE CLEANEST ENERGY SOURCE Solar cells convert sunlight directly to electricity. The solar cell is made of a semiconductor material with metal contacts on both sides, front and back. When sunlight strikes the solar cell, electrons are knocked loose and are moved by a voltage difference between the front and back sides of the solar cell, creating electricity. The process continues as long as the light is striking the solar cell, but stops instantly in darkness. OUTSTANDING SWEDISH RESEARCH IN PHOTOVOLTAIC TECHNOLOGY Sweden has wide-ranging research expertise in photovoltaic (solar cell) energy. Several multinational owner-operated companies are using and further developing Swedish research findings. The Ångström Solar Center is supporting research. The national co-financed “SolEl” programme for PV systems and applications is the foundation of Swedish research and development in the field. SolEl is a joint effort of the energy, construction and manufacturing sectors. Government investment grants are providing a platform for developing on-grid PV systems in public buildings. Sweden also grants funding for installation of PV systems, in addition to the long-standing grant programme for installation of solar collectors. Grants are also available for PV systems integrated in new buildings. HYBRIDS OF SOLAR AND OTHER TECHNOLOGIES Sweden has been developing various types of hybrid technologies for many years. For instance, these solutions are being used successfully in environments where conventional power infrastructure is unavailable, such as forests, remote rural areas and mountainous areas. Integration of solar electricity and solar heating modules – a hybrid technoogy that supplies waste heat and enhances efficiency. Solar cells, new battery technology and LED lighting – a hybrid technology for environments where there is no power line infrastructure. Solar energy offers a good alternative in places that lack reliable energy supply, such as rural areas in developing countries. The need and the potential are huge, especially since sun conditions in these places are often ideal. SOLAR ENERGY POTENTIAL IS HUGE, ESPECIALLY IN SUNNY COUNTRIES For a long time, it simply was not profitable to utilise solar energy except in places where there was no conventional power infrastructure. But the technology is advancing rapidly and vigorous support programmes have stimulated powerful market growth. • Solar energy accounted for less than one half-thousandth of world energy consumption in 2000. That figure is expected to increase to 20% by 2025. • The PV market has grown by about 40% a year in the 2000s. • EU target: 200 GW solar cells out of an estimated worldwide total of 1,000 GW by 2030. • Production costs are declining steadily as new technology is developed and production increases. • Consumer prices for solar energy are expected to drop by half in ten years. Estimated cost of solar energy in southern Europe: €0.15/kW in 2015, €0.06/kW in 2030. • Thin-film technology is lowering costs by about 80%. • Access to venture capital is abundant. PV CELLS – AN ECO-FRIENDLY AND RELIABLE ALTERNATIVE The sun’s resources are abundant and unlimited, which makes solar energy a very interesting alternative in the energy system of the future. • Sunlight is converted directly to electricity, with no moving parts and nothing consumed. • PV modules can fill multiple functions, such as replacing roof or facade materials or doing double duty as shades. • Maintenance costs are low. • Reliable technology, output guarantee on the modules (80% after 25 years). There are systems in Sweden still working beautifully after a quarter century. • The technology can be attractively integrated with the built environment. • Simple and modular, the technology can be adapted to preferred requirements. VARIOUS TECHNOLOGIES IN DEVELOPMENT Silicon-based solar cells are currently the most widely used technology for converting solar energy to electricity. The maximum efficiency of conversion is 15 to16%. Although reliable solar cell systems are commercially available today, further research and development is needed to reduce the costs and make large-scale distribution of solar cells possible. Research and development of several new solar cell technologies with the potential to improve efficiency and lower production costs are in progress all over the world. The development of thin-film PV cells (second-generation solar cells) has brought new technologies that are starting to break into the market. In parallel, development of third-generation solar cells, such as Grätzel cells, is in progress.

The PV modules are installed above the windows, meaning they also work as shades. The decision to install solar cells to protect students and teachers from the glare of the sun was taken in connection with an interior refurbishment. The system went operational in January 2007. Mellanhed School’s PV system won the Solar Energy Association of Sweden’s 2007 Solar Energy Award in 2007, with the following citation: “An architecturally well-integrated PV system of modules adapted to work as shades in connection with refurbishment. The system is designed for high energy efficiency while improving the indoor climate.

New hybrid technologies are expanding the possibilities for using solar energy. Swedish research and technology are far and away the leaders in this area, with products and technologies that have a sterling reputation in the global market. WIND POWER WIND POWER – AN INFINITE ENERGY RESOURCE A wind turbine is completely dependent on the wind. When the sun warms the atmosphere, it creates temperature differences. This in turn produces pressure differences that set air masses in motion – and the wind starts to blow. WIND POWER – AN INFINITE ENERGY RESOURCE Modern wind turbines capture about one third of the power in the wind that strikes the rotor. The blades on a wind turbine look something like a propeller and are linked to a generator that converts movement to energy. Wind is an almost infinite resource that costs nothing and creates no pollution. See principle WIND POWER – PRINCIPLE FAIR WINDS FOR SWEDISH WIND POWER There is considerable wind power potential in Sweden and the political message is to develop wind power in the country. Discussions are in progress about the expansion of groups of wind power farms. The planning will involve about 15 large wind power farms, each with about 100 wind turbines. Sweden’s large expanses of land, such as the inland areas in the north, are ideal sites for wind power. The environments are remote, far from recreational areas and communities and the sites are not classified as conservation areas. Sweden is currently running an extensive test project with the objective of running plug-in hybrid cars on wind turbine generated electricity. The Swedish automotive industry has demonstrated keen interest in the project. WIND IS A CLEAN AND ECO-FRIENDLY ENERGY SOURCE Wind power has many advantages from the environmental standpoint – the raw material is renewable and requires no alterations to the environment. • Very limited environmental impact • Production causes no environmentally harmful emissions • There are no hazardous residual products and final storage is not required • There are no fuel costs involved in production • Production requires no transport of raw materials • A standard wind turbine produces more energy in less than six months than it took to manufacture it WIND POWER IS A RAPIDLY GROWING ENERGY RESOURCE Total global production is still small, which gives wind power huge growth potential. Leading producers believe wind power will account for 10% of total world power production by 2015. Right now, Swedish wind power covers about 1% of the country’s total power consumption. Once the planned new production is operational, wind power will account for one third of Sweden’s electricity consumption. Wind power already covers 20% of electricity consumption in Denmark. In 30 years, an estimated half of all electricity will be generated by wind power turbines. Development is also advancing very rapidly in countries like Germany, Spain and the Netherlands. LILLGRUND – THE WORLD’S THIRD-LARGEST OFFSHORE WIND PARK Lillgrund is by far the biggest offshore wind power project in Sweden. The project, implemented by the Swedish energy company Vattenfall, is going to yield knowledge that large-scale offshore wind power works in purely technical and financial terms, which will pave the way for future projects. The farm consists of 48 turbines with total output of 110 MW. Total production in a normal year is estimated at 385 GWh.

Expansion is expected to increase by 25% a year for the next several years. There is tremendous potential for wind power in Sweden. The expansion rate is on par with the rest of the world, meaning that by 2015, about ten new wind turbines will be built every week. Offshore wind power will have to be exploited to accomplish a truly major expansion. LIGHTING LED – A LITTLE HIGH-TECH POWERHOUSE LED – Lighting Emitting Diode – is a young lighting technology that emerged in the 2000s, but is developing at warp speed. In another ten years or so, it is highly likely that most of our indoor and outdoor lighting will be powered by LED technology. LED – A LITTLE HIGH-TECH POWERHOUSE LEDs are semiconductors that directly convert electric current to light. The diodes emit colored light – red, orange, yellow, green or blue. White light is created using a special LED technology and is becoming more common all the time. NORDIC LIGHT INSPIRES DEVELOPMENT The Scandinavian winter is long and dark, and Scandinavians perhaps have a greater need than others for artificial light. It only makes sense that Sweden is a clear front-runner in the lighting segment, with regard to both research and manufacturing. • Swedish companies have developed a very useful technical platform for LED that is built into outdoor lighting fixtures. As an added bonus, the new LED fixtures costs less than conventional fixtures. • Jönköping University has been offering a degree in lighting design and planning for several years now. • Sweden has an abundant supply of professional lighting planners working as consultants in the lighting industry and large municipalities. • Quite a few Swedish manufacturers of lighting fixtures have a historic tradition of exporting good lighting solutions. LED – SUPERIOR LIGHTING TECHNOLOGY LED is an entirely new generation of lighting technology that is set to revolutionise the world in the next ten years. The technology has superior competitive advantages compared to low-energy light bulbs and incandescent bulbs. • LEDs have a lifetime of about 100,000 hours – a hundred times longer than a conventional light bulb. • The diodes are extremely energy efficient. About 50% of the energy in an LED is expended as light. In an ordinary light bulb, about 95% of the energy is expended as heat and only 5% as light. • LED lamps do not get as hot as halogen lamps. That makes LED lighting ideal for bookshelves and other cramped spaces that should not be allowed to overheat. • LEDs can withstand major temperature variations, providing an enormous range of applications, since installations are not affected by the climate or the season. • LEDs contain no environmentally hazardous substances like lead or mercury. LED – THE LIGHT SOURCE FOR THE FUTURE The minimal size of only a few millimetres won’t stop LEDs from becoming the technological lighting revolution of tomorrow. • LED technology has come a long way fast. Once used only in displays, it is now being used as a complete lighting alternative, indoors and out. • Within 10-15 years, a significant percentage of lighting around the world will be based on LED technology. • The technology is being continuously refined and LED lighting is getting better and more efficient all the time, in terms of both lighting and energy.
