 FINISH C3.2: Energy in the future

 C3.3: Water: Protecting the coast

Goals of last lessons

1. You can explain how 5 different types of sustainable energy work.
   
2. You can explain the what the energy transition means.
   
3. You can explain what the energy transition involves for the Netherlands.

C3.2: ENERGY OF THE FUTURE

ENERGY TRANSITION

The shift from using fossil fuels to using sustainable sources.

Think together with your neighbour:

What are the 5 sustainable energy sources and

name a disadvantage of each.

SOLAR ENERGY

Electricity generated sustainably using solar penals.

You can also use the sun to heat water.

WIND ENERGY

Electricity generated sustainably using wind turbines.

HYDRO-ELECTRICITY

Sustainable energy that is generated using falling water.

BIOMASS

Organic materials such as vegetable oils, wood and biodegredable waste (vegetables, fruit and garden waste).

GEOTHERMAL ENERGY

Sustainable energy from the natural heat deep inside the Earth.

 "Earth heat"

CHECK HOMEWORK

Wind, sun & biomass

4 a They are in coastal areas and in the sea, where there is a lot of wind and they cause the least nuisance to people.

 b See W4 on next dia.

 c solar panels, wind turbines and energy conservation (homes facing south)

USE FIGURE 8 & 10

5 The level of carbon dioxide does not change: CO2 is created when wood is burned. The CO2 is absorbed by trees; the wood from the trees is used to generate energy.

 

6 a Oil palms for biofuels instead of tropical rainforest.

 b Large areas of tropical rainforest were removed for cultivation of oil palms, a loss of nature areas.

TODAY'S GOALS

1. You know 2 reasons why the sea levels are rising.
   
2. You can explain the definition of relative sea-level rise.
   
3. You know 3 reasons for subsidence in the Netherlands.

You know 2 reasons why the sea levels are rising.

1. Climate change

        - Melting ice

        - Warm water expands

2. Subsidence

• See next slide

         "The bottom sinks"

You know 3 reasons for subsidence in the Netherlands.

1. "Seesaw" after the last ice age.
2. Pumping away rising groundwater.
3. The extraction of "minerals".

SUBSIDENCE

during/after the last ice age

You can explain the definition of relative sea-level rise.

You are able to explain how a polder works.

Read "Below sea level" in your coursebook.

Open page 84-85 in your GeoGuide.

Below sea level

Polders - Areas of land where water levels are controlled by man-made methods.

Reclaimed land

High- and low Netherlands

THE POLDER SYSTEM

THE POLDER SYSTEM

Sand suppletion - Putting a lot of extra sand along the coast to protect against rising sea levels.
