Energy Demand
By 2050:
2.5 billion more than today
double the number today
using twice as much
energy as now

Three hard truths will shape the
future of the ecosystem

Energy &
Climate Change
Impacts from climate change:
Temperature rise
sea level rise
massive biodiversity loss
increase of extreme events
Depletion of fresh water resources
Increase of vector born diseases economic and social instabilities
.
Climate change is real and a very serious threat to global stability
The greatest challenge
of the 21st century

People at the heart of the storylines
individually and collectively
People choose the easiest
option for them
Fear is not enough to
change behaviours
Climate change is too difficult
Delegating action to the state
Adapt rather than change

Solution:
Biofuel Generation from
Algae The current biofuel production process is highly
unsustainable (land use, energy requirements)
=> negative impact on agriculture
Biofuel generated from algae could solve these
issues:
- saving in energy
- saving in land use- high yield
Fuel of the future?

Solution: Carbon Sequestration
Sequestrating carbon emissions
underground is a safe process
Similar technology used for the
extraction of natural gas can be
applied
The carbon will remain trapped
for millions of years

Solution: Renewable
Energies on a Large Scale
A combine use of renewable energy sources couldmeet our current energy needs:
- Solar energy (photovoltaic and thermal)
- Hydroelectric energy
- Wind energy
- Geothermal energy
- Ocean Thermal energy
- Ocean wave energy
- Tidal and currents energy
These technologies are available today
We must however rapidly make the shift going awayfrom fossil fuel based energies
-

Solution: Sustainable
Transportation
Transportation accounts for almost one
third of all greenhouse gas emissions
Improving energy efficiency and
emission reducing technologies within
transport is a priority
- Hybrids
- Fuel cells
- CNG vehicles
- Mass public transportation
- Human energy vehicles
- Solar and wind energy vehicles

Hope: Nuclear Fusion Currently used nuclear fission is a clean process
when it comes to emissions but it generatesradioactive waste and poses security risks
Fusion is the energy of the future by excellence Clean process occurring within the sun
It can be done
Major problems remaining to be solved:
- Maintaining a stable reaction
- Confining the extremely hot plasma
We might be able to harvest fusion energy in 50 yearstime
However, our climate will not waitother alternatives mustbe put into place

Waste
Facts:
Cities are growing fast
Landfills are reaching saturation/
incineration produces emissions
Waste has a lot ofvalue but is notexploited
We must shift from a global unsustainable
waste management model to a sustainable
one

Garbage Output
Waste Output 2002: 7,677 tonnes/day
Equivalent to1,100truck loads!
Equivalent to 2.8 million tonnes/yr
If stacked to an average mans height
(1.7m), it would occupy 350footballfields

Solution: Waste to
Energy
By 2050 80% of the world population
will be living in mega cities
The tremendous amount of waste
generated can be valued
Entire cities can be powered out of
energy generated from waste
- Capture of gases (CO2 & CH4)- Use of heat energy generated from the
decomposition process

Engineering
Non-traditional waste recovery

Solution: Traditional
Recycling
Value waste
Use of recycled content within
products
Reduce massive consumerisms
1) Educating the community
2) Implementation of infrastructures to
treat the waste accordingly
Technology will not solve all our problems,we must also change our behaviors

Nature &
conservation
Facts:
. Species are going extinct at least 1000 times
faster than the natural rate
We could lose 30-40% ofall species on the
planet through the impacts of climate change
alone by the end of the century
At the current rate primary forests will have
completely disappeared in places such as Borneo
or PNG within 20-30 years
-

Solution: Sustainable
Cities
Cities of the future must incorporate
nature (green walls, green roof tops,
natural parks, connectors)
Green buildings (energy efficiency)
Good water management
Good waste management
Most importantly, biodiversity and
natural ecosystems around cities
should be preserved at all costs
They have a critical role to play

Solution: Learning
from Nature
We have a lot to learn from ourenvironment:
We must understand that there istremendous amount of knowledge which
will disappear with the loss ofbiodiversity
- Potential remedies and medicines
- Potential for optimal design(biomimetics)
The preservation of biodiversity is crucialin our own interest
Biomimetics is the study of nature to
come up with innovative ideas and
optimal designs

We know more about our solar system them we do about life in
the deep oceans of our own planet!

Solution: Valuing
Nature There is a lot of economical gain inpreserving our environment:
Revenues generated from:
Ecotourism
Agroforestry Medicines
We must learn to work with our
environment and not against it
The destruction and loss of natural
ecosystems will end up costing much more
than their destruction for short term profit

Awareness
In order to judge we need to know what we are
losing
Sharing of knowledge => Snow-Ball effect
Awareness is primordial
Small actions by individuals can lead tosignificant changes if applied on a large scale
Share your knowledge
You are in a position
to influence people

Current Model vs. Future Sustainable Society
At the current rate we will
need at least 2 planet Earth
by 2050

Is not sustainable
