1. THE INFLUENCE OF LIGHT POLLUTION ON CLIMATE CHANGE

2. WHAT IS LIGHT POLLUTION?
(disturbing light) is definied as artifical light produced and wasted by humanity,
it disrupts natural level luminosity of night environment.

3. THE SKY IN DIFFERENT PLACES

4. VERY DARK SKY
THE SKY OVER LEGNICA

5. The source of light pollution is mainly outdoor illumination and in particular the one which is:
badly directed,
has improper emission spectrum,
lighter than we need,
turned on when it isn’t used.
Wrong street light (left side) causes wasting of light and brightening the night sky. Good lighting(right side ) allows to effectively use artifical light and keep view of starry night.

7. WAYS OF STREET LIGHTING

8. OUR TOWN
AT NIGHT

9. THE SOURCES OF LIGHT POLLUTION
flickering ads
brightly glowing signs of shops
illuminated facades of buildings

10. THE SOURCES OF LIGHT POLLUTION
light of shopping malls open to late hours
illuminations
widespread street lighting

11. THE INFLUENCE OF LIGHT POLLUTION
Outside light which doesn’t light where is needed or light too brightly is
a waste of electricity.
Producing energy from non- renewable sources has a negative influence on the environment and the climate.
The majority of greenhouse gases is produced from coal burning.

13. RENEWABLE SOURCES (about 12%)
THE SOURCES OF ENERGY
IN POLAND
GAS
(about 3,5%)
BLACK COAL (about 50%)
RENEWABLE SOURCES (about 12%)
BROWN COAL
about 31%)
THE OTHERS
( about 3,5%)

14. OVERUSE OF ARTIFICIAL LIGHTING CLIMATE CHANGE
increased cost of power production
increased consumption of coal for energy production
CLIMATE CHANGE
increased emission of CO2,

15. THE IMPACT OF THE INCREASED CO2 on GLOBAL WARMING
The greenhouse effect
Moving of climate zones
Devastating hurricanes, floods, cyclones, droughts and fires
Animal migration
Ocean level rise
Melting of glaciers

16. ATMOSPHERE
The sunlight reflected from the earth goes into space
The amount of the earth heat radiates into space
GREENHOUSE GASES
( mainly CO₂)
The majority of the earth heat is stopped by greenhause gases
The sunlight comes onto the earth
The earth surface warmed by the sun radiates the heat back to the atmosphere
THE EARTH

17. THE GREENHOUSE EFFECT LEADS TO
GLOBAL WARMING
GLOBAL TEMPERATURE
The average temperature within one year
The average temperature within five years

18. GLOBAL WARMING EFFECTS
HURRICANES OR ORKANS
HEAVY RAIN, SNOW FALL, HAIL
FLOOD
DROUGHT

19. The renewable sources of energy should be used more often.

20. sources of Energy in Europe
Renewable
sources of Energy in
Europe
POLAND 12 %

24. Do you know…….
that in Poland there are about 3,3 mln street lamps out of which 60% are traditional ones – they use a lot of energy,
in the next few years most of Polish municipalities plan to replace traditional lamps with led ones and introduce the intelligent systems of street lamp steerage,
this solution will allow to save over 80% of energy.
