VISION
- Meeting the Carbon Challenge
We are on the edge of a new energy
revolution. The coming decades will bring huge
changes to energy systems throughout the
world. The challenge will be to provide eight
billion people with energy and, at the same time,
protect resources and the environment. Technolog
y will most certainly be fundamental in making it
possible to meet the worlds growing energy needs
in a socially and environmentally responsible way.

A Bright Green Strategy
Tackling climate change is a pro-growth strategy
Economic growth and welfare can be maintained
without influencing the climate negatively This
is what we have experienced in Denmark, and this
is what we call "The Bright Green
Strategy" Here technology has a central role to
play

The case of Denmark Wealth-creation at constant
energy consumption
The Danish gross domestic product (GDP) grew by
75 pct. from 1980 to 2006 (at constant prices).
In the same period the consumption of energy in
Denmark has been more or less constant. This
means that each unit of GDP requires
approximately 40 per cent less energy today than
in 1980

Renewables are only part of the answer
Innovative solutions for reduction of CO2
emissions
  • Efficient energy generation
  • Highly efficient gas and steam turbines
  • Coal carbon capture storage (CCS)
  • Cogeneration
  • Switch to renewables
  • Wind
  • Biomass
  • Solar
  • Efficient energy distribution
  • Smart grid
  • High-voltage DC transmission systems
  • Distributed heating and cooling systems

Meeting the carbon challenge
Making the right choices
  • Some comments
  • All technologies, including renewables, must
    be in play in order reach the carbon goal
  • However, we need to fix the order of priority
    in order to reach the goal in an efficient
    manner
  • Energy efficiency has a vital role to play
    and must not be forgotten
  • Higher focus on energy efficiency will also
    ease the effort to reach the targets for
    renewables
  • - Multiple business opportunities

Making the right choices
Short term and long term
  • Many future alternatives exits
  • However, in the short term we need to focus on
    deploying existing, well proven and fully
    available technologies
  • Especially technologies improving energy
    efficiency need to be in focus if we are going to
    reach the objectives of bringing down
    CO2-emissions
  • Some of these technologies will also increase the
    share of renewables, especially district heating
    and cooling technologies

Meeting the carbon challenge
Before 2020
  • District heating and cooling technology the
    most energy efficient form of energy production
    (combined electricity and heating)
  • Biomass heating technology Co2 natural and
    attractive alternative to oil and gas
  • Heat pump technology high efficient heat pumps
    as the best alternative to individual oil and gas
    boilers
  • Comfort controls technology to reduce energy
    use for comfort heating and to increase human
    comfort
  • Energy audits and trimming to reduce energy
    usage

All the above mentioned alternatives are based on
existing, well proven and fully available
technologies

District heating and cogeneration
The sleeping giant
  • Lower import dependency of 4.5 EJ or the
    equivalent of Polands energy supply
  • Giving a reduction of the primary energy supply
    of 2.1 EJ or the equivalent of Swedens energy
    supply
  • Reduction of 400 million tons CO2 per year or
    the equivalent of the emissions from fuel
    combustion in France
  • Higher share of renewables as district heating is
    a common carrier for renewables like wind,
    biomass, solar .

District Heating example Increasing the
District Heating share from its current 6 to 12
in Europe will have major effects

Conclusion
A Bright Green Future
With climate change hard upon us, a new green
movement is taking shape - one that embraces the
concerns of environmentalism but rejects its
worn-out answers. Renewables are part of the
solution But, we all have an obligation to make
sure that we use existing, well proven and fully
available technologies to secure immediately
improvements of energy efficiency and CO2
reductions This is a Bright Green Strategy
