Energy is ……

�Energy is the ability to do work.


Sources of energy in the rural

areas,

� Use of kerosene

� · Electricity, solar

� LPG (very few)

� · Use of dry husks

� · Use of saw-dust

� Fuel wood, shrubs

� Charcoal

� Crop residues-maize cob ,stoovers, grasses,sugar c

� Dried Cow dung


Facts about energy in the

world

� Half the world’s people must burn wood or dried dung to cook their food.

� Nearly 1.2 billion people, a fifth of the world’s population, do not have access to clean drinking water.

� Over 1 million children die yearly because of un-boiled drinking water.

� Wood cut for cooking purposes contributes to the 16 million hectares of forest destroyed annually.

� Half the world’s population is exposed to indoor air pollution, mainly the result of burning solid fuels for cooking and heating.


Facts about energy in

Greatlakes region

�90% of population in lake Victoria region

live in rural areas

�90% of the rural households and 10%in the

urban use fuel wood as primary source of

energy for cooking and heating (ibid)

�80% of Hh obtain fuel wood free but a

greater number is now buying it.


Some strategies to put in place

With increasing populations and thus higher increase for demand for fuel wood (more trees cut ) we need to

� Increase production of tree biomass for fuel wood, income carbon sequestration and adaptation to climate change .

� Improved wood saving devises for household cooking in rural areas.

�Use of other sustainable alternative sources of energy


Cont.

�One important method, to keep our

environment sustainable is by reducing on

fuel wood consumption. Energy

conservation

�The second method is to maximize the

energy output from the available fuel wood

by use of efficient fuel wood burning.

Energy efficiency


Energy conservation

Is the practice of decreasing the quantity of

energy used while achieving a similar

outcome

Efficient energy use, sometimes simply

called energy efficiency, is using less

energy to provide the same level of energy

service.


Traditional metal stoves


Traditional three stones stove


Why use Energy Saving

Stoves?

�· Minimize high consumption of fuel wood/charcoal

�· Provide time to women for other development activities

�· Promotion of the utilization of local resources

�· Environmental sanitation due to effective use of waste


Why use Energy Saving

Stoves?

�waste product (e.g. Sawdust, husks etc.) of

which could have been thrown away

�· Safeguard of the community and the

Environment as a whole


Example of energy saving

stoves:-

Mud /clay Stove.

�Made-up from clay soil, grass and sand


Mud /clay Stove.


Mud stoves


Kenya ceramic jiko


K C J

�The KCJ reduces fuel use by between 30 to 50%. This means less wood is burned to make charcoal, and fewer trees have to be cut down., less labor in looking for and chopping firewood, reduced emissions from incomplete combustion, such as toxic gases( greenhouse gases) and particulate matter, resulting in better overall health of the users.


Chepkube jiko

�Chepkube stove

�Made-up from clay soils, grass, sand and

burned bricks

Liner stove/ Jiko la Kigae

�Liner stove

�Made-up from stones, clay soils and liner

(ready made by e.g. keyo women group)


Upesi jiko


Kuni mbili jiko


Six bricks jiko


Rocket stove

�The idea of a rocket stove is that it has “an elbow”.

Fuel is fed to the combustion chamber through

vertical J-shaped elbow or horizontal L-shaped fuel

magazine. Fuel magazine is small for two reasons: it

encourages the user to feed wood in bit by bit and

also it stops too much cool air to enter combustion

chamber.

�Very often rocket mud stoves also have external

chimneys to remove smoke from the kitchen.

Husks stove/ Jiko la Pumba

Husks stove/saw dust jiko

Ready made by local artisans Make

use of husks from rice and saw-

dust


Fireless cookers/food warmers

�Made-up from black pillow with husks or sawdust.

�FC saves up to 50% of cooking energy

� If used regularly in combination with improved cook stoves, an additional 40% energy is saved.

�This saves equivalent to 4.1 million tones of wood or 12.2 billion shillings annually.

�This saving contributes to avoided deforestation as more trees are saved.
