A global energy revolution
is both necessary and
inevitable!

“much better than expected”?
“Over the past two years, sea levels
have not increased at all — actually,
they show a slight drop. Should we
not be told that this is much better
than expected?“

High CO2 causing ocean acidification

Updated Reasons for Concern

(Smith et al. 2009 PNAS)
Why should we stop burning fossil
fuels?
Because of their
contribution to
climate change.
Because fossil fuels
create geopolitical
tensions (national
security issues,
economic
vulnerability of
fluctuating fuel
prices, energy
security..)
Because fossil fuels
are finite resources –
oil: 41 years, natural
gas: 60 years, coal:
133 years (source: BP Statistical

64 mb/d of gross capacity needs to be installed between 2007 & 2030 – six times the current
capacity of Saudi Arabia – to meet demand growth & offset decline

tensions.

Future energy

secure...
Danmark’s energy source: world expert
in renewable energy but there’s a long
way to go!

Even the International Energy
Agency says that an ”Energy
Revolution” is necessary
Note:
In revolutions there are winners and
losers…
Winners understand what
challenges the future will bring and
are ready to handle them.
In the midst of the COP process…
A transition to non-fossil fuel energy
sources is a necessity and a prerequisite
for economic growth in the not too distant
future!
We need to change the way we think and speak
about dealing with climate change!
There is also a world after December 2009!!
