A crash course in changing the world.
Solar or Biogas; Take your pick!
The only source of energy I use in my home is Hydro Electric Power. It is the most common in Uganda today. Very expensive however but we don’t
have many options. One of the options is solar which is really expensive in
terms of initial set up costs.
Hydro Electric Power is relatively cheap in terms of initial costs of connection however it’s pretty expensive to maintain in the long run.
In my house I use “Energy Saving Bulbs” (15Watts) these save 80% of the power I use daily. I have no
control over the power consumption on my television, refrigerator or percolator.
My laptop is pretty much power efficient because I keep it in the power saving
mode even when I charging it. Of course I also use my flat iron every day – for
this I have a 1000watt flatiron.
I use all these equipments everyday but because hydro power remains very expensive I need alternative ways to power my house cheaply.
I have a couple of ideas:
-
Solar energy; considering the sun is a free
resource in Uganda and there most of the year. However I have to put in
consideration the cost of solar panel which like I said remain very expensive
in Uganda. This seems to be the only limitation. However I have to say that
this would have been a perfect choice.
-
Biogas; behind my house is a big septic tank.
Most of the houses in my neighborhood have a septic which act as a temporally or
permanent storage for sewage. From what I read about biogas I think we can use
these septic tanks “more” productively to facilitate power generation from the
sewage stored in them. To me this seems to be a more sustainable idea and could
be relatively cheaper if 5 or 6 families from the same neighborhood can put
resources together to contribute towards the costs for initial set up.
At the moment I think I will choose Biogas over Solar. I have to do a little bit of more research on this and would love to hear what you have to say about it.

Ssozi- both biogas and solar energy should definitely be more widely used. One way to cut down on the cost of solar energy is to incorporate passive solar design into the building of houses. This need not be difficult and shouldn't add much, if anything to building costs.
Biogas technology is also a great option, considering that everyone has access to the waste materials that can produce it. On the other hand, the technology seems to be somewhat complicated. While I've read many articles suggesting that do-it-yourself installation of solar panels would be possible for many people, a home biogas system would require more skill, since you are dealing with potentially dangerous ga****. For neighborhoods, though, a biogas system would be a great idea, just as you say.

Agent Sarah,
You are right, biogas and solar should be more widely used.
And I like your idea of cutting down cost that you are suggesting.
Actually with the ideas and suggestions you are providing here I will have to do more reading on this.

In this blog post I will focus on a plant that is abundant in our nature, and which is immensely nutritious. It's of course the Stinging Nettle. Let's start with the chemical constituents of this plant:37 % Non-Nitrogen-Extracts19 - 29 % Ash9 - 21 % Fiber4 % Fat22 % ProteinOnce the leaves are drid, their protein content can reach an astounding 40 %, which is much higher than beef, which even under the best of circ**stances can never exceed 31 % protein.

The meal
It is 7'oclock, I was late home from work due to an assignment that i wanted to get ahead on. By the time I get home I am feeling extremley tired and I cannot be bothered to make a proper meal. I walk to the fridge and open it to see what there is for me to eat. All of the out of date foodstuffs have been automaticaly thrown away by the fridge, they will be recycled tomorrow as animal feed or something. I see i have organic local eggs and some local cheese.
