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, RD 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 Swedens considerable
expertise in CleanTech
4
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 Swedens 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
pumps 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.
6
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

7
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.
8
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

9
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 buildings 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.
10
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

11
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.
12
WHY IS SOLAR ENERGY A GOOD IDEA?
The suns 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.
13
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 rotors 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.
14
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

15
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.
16
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.

17
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
20
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 pumps 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.
21
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

22
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

23
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. Todays 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.
24
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.

HEAT PUMPS A POWERFUL ALTERNATIVE
Heat pumps are an eco-friendly alternative that
reduce the use of electric heat, oil and gas. 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
35
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.
36
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.
37
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

38
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.
39
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

40
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.
41
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.

RISING TO FUTURE CHALLENGES
District heating is a highly versatile system
that can be produced using the technique and
fuels that are optimal for the time and place.
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
50
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 buildings 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 ?
51
DISTRICT COOLING PRINCIPLE
52
SWEDEN IS A PIONEERING COUNTRY IN DISTRICT
COOLING
Swedens 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.
53
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

54
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

55
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
64
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.
65
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.
66
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. Governmen
t 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.
67
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.
68
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.

69
PV CELLS AN ECO-FRIENDLY AND RELIABLE
ALTERNATIVE
  • The suns 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.

70
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.

There are 251 m2 of solar cells installed at
Mellanhed School in Malmö, with peak output of 31
kW. 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 Schools PV system won
the Solar Energy Association of Swedens 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. The choice to
install the system at a school also gives it high
educational value.

THE FUTURE OF SOLAR ENERGY
Solar energy is probably the most important
alternative for the energy system of the future.
Technology is developing very rapidly, thanks to
successful research, tougher environmental
policies worldwide and good access to venture
capital. Far more than a billion people still
have no access to electricity. In the future,
solar energy is probably going to play a crucial
role in their lives. 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
82
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.
83
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 ?
84
WIND POWER PRINCIPLE
85
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. Swedens 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.
86
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

87
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 countrys total power
consumption. Once the planned new production is
operational, wind power will account for one
third of Swedens 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.
88
LILLGRUND THE WORLDS 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.

LIGHTING
100
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.
101
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.
102
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.

103
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.

104
LED THE LIGHT SOURCE FOR THE FUTURE
  • The minimal size of only a few millimetres wont
    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.
