Summary chapter 6
6.1
Global warming
The climate on Earth is changing because of our use for fossil fuels.
= natural gas, oil, coal
> factories, traffic, heating installations and electricity power stations
pump extra CO² into the air
CO² is a greenhouse gas that traps heat in the atmosphere
> natural process is good for life: otherwise it would be ice-cold on Earth
> but huge amount of extra emissions: enhanced greenhouse effect
Effects of global warming:
- Ice and snow in the mountains and at the poles are melting
- More extreme climate
> in the Netherlands too
Less CO² in the atmosphere
Most countries want to do something to stop climate change
> 2030: cut CO² in half
> 2050: Netherlands climate neutral
Possibilities:
Energy conservation: use less energy
> E.g.: at home and when travelling
Use new energy sources
> fossil energy sources: emit CO² into the air and might run out
, > sustainable / renewable energy sources: do not emit CO² and never
run out
> energy transition= changeover from fossil to sustainable energy
sources
From grey to green
The Netherlands still only produces a small amount of sustainable energy
Wind energy:
- Advantages:
+ clean
+ keeps getting bigger, better, cheaper
- Disadvantages:
+ reliability
+ noise
+ ugly
> offshore wind farms: cost more, but produce more energy
Solar energy:
- Disadvantage: reliability
> lower production in winter
Air source and geothermal heat: heat pumps for heating homes and
tap water
Biomass: organic matter
> leftover wood, vegetables, fruit, garden waste, paper waste, vegetable
oil, manure
> burned to generate electricity and as biofuel
