Slide 9 - Slide

Alternative
energy sources

Slide 10 - Mind map

Alternative 1 - motion
  • Windturbine
  • Hydroelectricity (river)
  • Tidal power (ebb and flow)
  • Waves of the sea (experimental)

Slide 11 - Slide

Alternative 2 - Plants
Biofuels are made from maize, cole seed and sugar cane.

Is it sustainable?

Disadvantage - 
A lot of agricultural
ground is used.

Slide 12 - Slide

Biofuel or alcohol out of agricultural waste.

Then the production of
food and biofuels go
hand in hand.

Slide 13 - Slide

Alternative 3 - The sun

  • Solar panels - electricity without waste products
  • Easy to use, and can be used everywhere.
  • Deliver excess electricity back to the grid.
  • No electricity at night (But during day time batteries can be charged. This happens at trafficlights, drinking troughs for cattle and streetlights)

Slide 14 - Slide

Solution for the
increase in demand
of energy

Slide 15 - Mind map

Solutions for the increase in demand:

  1. Use sustainable energy
  2. Use smart appliances
  3. Dont waste energy

Slide 16 - Slide

Meat or plants?

Slide 17 - Mind map

Meat or plants?
Greenhouse effect - The process whereby the atmosphere makes the earth warmer.
Greenhouse gasses are: 
  • Carbondioxide
  • Watervapour
  • Methane

Slide 18 - Slide

Meat or plants?
  • Production of meat uses 6 times more energy
  • more land is needed for animals as opposed to plants 
  • Methane gas is relesed by animals, but plant absorb CO2
