Biomass Energy- The Sahel- Fuelwood- Case Study Flashcards
Provide some statistics that prove the use of fuel wood in the Sahel for cooking in the Sahel is a bad thing.
1.5 million people a year die from the cooking fires there.
A solar cooker is a _____ and _____ ______ form of cooker.
Cheap and low energy.
What type of countries are solar cookers suitable for?
Hot countries with little cloud cover- perfect for The Sahel.
How do solar cookers work?

It is appropriate technology- foul and card board- available resources
- sun’s abundant, free and renewable
- can cook upto 2 meals// day- meat/ fish/ rice/ cornmeal- can reach temps of 250 degrees Fahrenheit
List advantages that come with the use of solar cookers for cooking in The Sahel over fuel wood.
*cheap to make
*save 1.5m deaths from
fires a year
*reduce fuel wood use 80 %
*chance for industry and jobs/ cookers can be made and sold by locals
*less time spent on cooking- more time for work and education (ec+soc)
*less need for and time spent collecting fuel wood- social adv
What are two knock on good effects that reduced fuel wood usage by 80% in the Sahel with the introduction of solar cooker cooking can bring?
- higher quality topsoil.
* reduces deforestation- lower CO2 levels impact.
List four disadvantages of using solar cookers as an alternative for fuel wood cooking in The Sahel.
- cooking takes longer
- smokey taste could be missed
- low level community backing- live traditionally- necessary to work
- tend to not be v durable- deteriorate fast so reg replacements needed
Explain the problem The Sahel is facing in how it is struggling to reduce its dependability on fuel wood.
90% of cooking in the Sahel is dependant on fuel wood (413mil people rely on it)- hard to stop use as; can’t afford other energy/ fuel alternatives cost more than 45% populations average wage.
