Vision 2050 - Background
The world energy system:
is beyond the environmental limits
does not provide basic energy needs as light and
healthy cooking facilities to 2 billions of the world’s
population
To avoid dangerous climate change we must limit
global warming to 1ºC in the 21st Century
We should provide all with basic energy needs and
allow developing countries to develop, including use
of cheap energy supply
INFORSE

Environmental Limit:
Climate Change
To
be sure to keep global warming below 1ºC
century, we must limit global CO2 emissions to
about 250 Gigaton of Carbon in 21st century =
35 years of current consumption (assumed
climate sensitivity of 3.5ºC)
The
climate sensitivity is commonly accepted
to be in the range of 2 to 5ºC with an average
of 3.5ºC.

Energy Demand
Most energy consuming equipment will be replaced
several times before 2050: new generations of
equipment should maximize efficiency. Technology
learning can drive prices down.
One exception is houses. In EU houses could use
only 1/7 of todays heat demand in 2050. This will
require renovation/re-building of 2% p.a. / heat
consumption 20-40 kWh/year per m2
For transport is expected increase in efficiency from
todays 15-20% to 50%, and re-gain of “break
energy”. Hydrogen and fuel cells as solutions
together with electrical driven vehicles.
Energy service demand will increase, also in
industrialized countries, energy demand decrease.

Energy Supply
Wind: Follow Windforce10 growth from todays 20,000
MW to reach 3,000,000 MW in 2040, then maybe
less afterwards
Large wind power development programs are costeffective: extra costs today will be paid back with
future cost reductions due to technology learning.
Some sites give cost-effective electricity today.
Solar: PV could reach 500 MWpeak in 2003, and then
grow 25% pr. year
Biomass and hydro: Increase 30-50% in total
Biomass can be used as transport fuel

Economy - DK scenario until 2030
The
low-energy scenario is 2% cheaper than the
business-as-usual scenario with zero discount rate
It is 1% more expensive with 5% discount rate
If environmental costs are included or if fossil fuel
prices increases more than estimated by IEA, the
low-energy scenario is considerably cheaper than
business as usual.
expected lower growth in energy services: need for
decoupling of economy and energy services

Energy Infrastructure
Electricity grid still needed, as today
Electricity grid needs more regulation with many
decentralised production units ”intelligent grid”
Need for electricity storage to compensate wind &
PV, in Slovakia hydro pump-storage, in Denmark
probably chemical storage after 2030
New roles for electricity: transport, heat pumps,
international energy trade
Nuclear phase-out 2010-2030 or earlier
Because of large learning rates for the new
technologies, minimal costs.
INFORSE
International Network for Sustainable Energy
More on Infrastructure
decentralised power production, to use local
renewables and to cover heat demand (CHP)
more investments in demand-side efficiency, less in
energy supply, after transition phase 2000-2030
gas demand stable until 2025, then decline
hydrogen – fuel cell systems for transport and to
replace gas where local renewables insufficient
some gas networks can be used for hydrogen
heat networks to remain in densely built areas
