Energy and Sustainability
building a sustainable energy future - without the hot air
Samo Fürst, GEN energija
We need energy literacy to make
informed decisions about our
energy future.
Energy:
- Why?
- How much?
- When?
- Where does it come from?
- Decision factors?
1 kilowatt hour =
40 W light bulb / 24 hours
- Food (chemical energy) = 3 kWh/day/person
- Hot bath = 5 kWh of heat
- Car drive (35 km/day, consumption 7 L/100
km) = 24 kWh/day

Energy primary sources and its
consumption in Slovenia
Energy use means unavoidable losses
Slovenia’s primary source consumption is roughly
hours (kWh)
113 kilowatt-
per day per person.
In practical terms, this is the amount of energy one hundred and
thirteen 40-watt light bulbs would use if left turned on by a single
person around the clock, every day of the year.
Slovenian energy balance
Energy unit: kWh/capita/day

Electricity consumption & production in

2055 – Šoštanj TPP closed
Decisions are needed today!

- How to provide affordable,
reliable supply of energy,
which takes into account the
principles of environmental

Factors influencing decisions
Slovenian commitments to the EU – climate and energy targets
- Reduction of CO2 emissions; total emissions reductions of 30% to
40% by 2030
- Indicative targets for 2050; 80% to 90% reduction in the overall
reduction of CO2 emissions
- The share of renewable energy sources; 25% by 2020
Life cycle impacts shall be
considered
All impacts shall be taken into account!
Planning vs NIMBY (Not In My
Back Yard)
Irresponsibility is unsustainable!
Climate change is (perceived as)
one of the most serious threats to
mankind

Climate change is a fact!
Climate change driver: CO2 at
record level of 400ppm
• 400ppm is record level in the
last 800.000 years (data from
Antarctic ice)
• This level was last reached 3
million years ago
• Ice ages repeated every
100.000 years; CO2 level was
from 180ppm to 280ppm
Climate change is a fact!
ESCII:
2,39 tCO2/toe in 1990

The key directions for Slovenian
sustainable energy future are:
- electrification of the transport and heating sector,
- electricity generation from sustainable and renewable
sources (nuclear and hydro energy),
- reduction of fossil fuels and focus on natural gas as the
cleanest of them,
- better use of energy sources available due to our natural
characteristics - biomass for heating,
- energy efficiency measures (- 20%, - 30%?)…
>>> EXPECTED RESULTS:
- less energy import dependency > more energy security
- less CO2 emissions
- reliable energy supply at competitive prices

Investing in new production capacity
EXPANDING NUCLEAR CAPACITIES FOR
ELECTRICITY PRODUCTION
•
Investment in the construction of a
second unit of Krško NPP (Krško 2).
OTHER INVESTMENTS
•
Completing the chain of hydroelectric
power plants on the lower and middle
course of the Sava River
•
Replacement of gas units PB 1, 2, 3 at
Termoelektrarna Brestanica (TEB) –
assessing the viability of investing in a
gas-steam unit.
•
Investments in the future, with a focus on
renewable and sustainable energy
sources.
JEK 2 and sustainable
development of Slovenia
• Optimal land
requirements and
nature conservation
Environment
• Low carbon source of
energy
• Domestic source of
energy
• District Heating
• Highly qualified jobs
• Pressurized water
reactor, 3th generation
with improved technology
and security
• Usage of recycled fuel
Society
