All this small scale industry is reducing costs, providing light and reducing use of fossil fuel and wood, which can be better used, as well as improving health in dwellings.
It is an obvious solution for rural areas.
Surely heating water by solar should be even easier, leading to better hygiene and health. Solar ovens will surely also work here.

Battery maintenance is often listed as a reason non-grid-tied power is too much bother here in the U.S. Yet the Barefoot College site seems to indicate it is not much of a problem.

Maybe programs like this will end up in the U.S. as well, eventually.

It is no doubt that Solar Energy is the way to go. It is environmentally friendly and sustainable. It has countless advantages over conventional energy. It also makes economic sense and should be exploited to the fullest. Unfortunately, Africans and their Governments are slow to embrace this Green technology that can be harnessed free from the abundant SUN.

Kenya was a pretty big market for off-grid PV back in the day (i.e. the days when off-grid PV was 95% of the market). See this page from UC Berkeley documenting success from way back in 2000:

Mary:
Battery powered systems are a reasonable approach when you have no power grid and your energy consumption is quite low. These are two situations we would not want to see in the US. If all you want to power is a single lightbulb you don't need the large lead acid battery arrays designed to withstand deep discharge that are often used in off grid applications requiring large power.

What these Kenya women are doing is exactly what we intend to do for Nigeria rural areas.
I will appreciate information from anyone that will link us up with Barefoot College in India. We intend to partner with them too but this time, to understudy the methodology of training with a few to replicate same in Nigeria.
Another organisation of interest will be Lighting Africa Private Enterprise Partnership for Africa (LAPEPA). The purpose is to learn from them.
Organisation such as First Solar of America and some others, can be of help here and in return, we shall help them to market their off grid panel comprising of Solar Panel, Inverter, Battery and other accessories to middle class Nigerians who are tired of the epileptic supply from power authority.

It is wonderful idea to light the remote villages with Solar PV System, provided there should be a system/ institutions to back the huge initial investments needed. Instead, they can go for a power generating system powered by farm animals. We at NeoEnergie Corporation is doing the same by manufacturing Animal Propelled Energy Generators. This generator is clean, green and ideal for rural folks, who owns any type of animals used for rural transportation. If you are interested to know more about our products, please feel free to contact us at neoenergiein@gmail.com

Kenya is a good example for the United States, to change from a traditional energy source, to modern science technological energy saving alternative.Thank you.

My energy consumption is very low. I use a kind of crummy low-energy use computer and unplug almost everything else so as to have a low ghostload. I avoid TV, a common behavior where I live.

I have a friend who flips her breaker in the summer. I'm not as connected to Food Not Bombs as she is. I use a refrigerator.

I drive around in a generator (Prius). Maybe some day my generator will interact with my house the way the grid in some places interacts with advanced storage methods.

There are issues for minimalists.

The power company may report you as nuts if your usage is low, especially dangerous if you are old. They may start trying to take your property for code violations. Reports of nuttiness in elders get more action from social services if they are reported by third parties rather than by family members.

They may send someone out to check your meter because they think you are loaded up with your own generation so as to grow medicine under the radar.

My point in writing this is that there are plenty of young wanna-be village people in the U.S.

For energy professionals to think they will behave as their parents did probably is an error, more so in some locales than others. It is going to be hard to measure or anticipate the changes in behavior that will manifest in the aggregate. Intel knows this and hires specialists to anticipate change.

I hang out quite a bit with people who are the age of my adult children. They behave far less similarly to my generation than I have to my parents'. Part of this is by necessity. Many jobs that used to be no longer exist. Part of it is choice and cannot be expected to change if jobs begin to show up again.

The anthropology of energy use is fascinating to me. I see hope in arranging access in places formerly without and in encouraging more reasonable use in places which have been profligate.

Mary,
Solar lamps probably have a low-power LED bulb and require very little energy. Such a device could use batteries such as NiMH. If you want to run refrigerators and similarly large devices you probably need lead acid batteries. Those are significantly less convenient and cheap, but allow larder loads. My initial comment (#6) was merely about this technical issue.

You seem to encounter a different class of young people than I do; those I meet are addicted to quite an array of electronic devices. I'm all for attenuating profligate usage patterns (although I suspect our definition of what profligate is differs somewhat, as apparently does our definition of "medicine"), but I don't see an increased reliance on batteries as a step forward. Grid access is far more environmentally friendly than large arrays of inefficient batteries that need to be replaced frequently. Many parts of the world don't enjoy grid access so they must seek alternatives, but the US does and I see no rational reason not to take advantage of it.

Steven,
My initial post is more about getting women in renewable energy than promoting batteries, but I do think higher prices or reliability issues can incentivize going off grid and advocacy for the formation of micro-grids, which create more employment for locals.

The employment situation is worrisome, and people become resourceful under stress. If they make change or decide to push for it, they may not go back to previous habits even if jobs come back.

When gas prices went up, households here moved to biomass for heat. People are also aware that we risk earthquake disruption.

The number of people doing everything with bikes here is pretty remarkable. Have you ever seen a bike-powered blender?

The Village Building Convergence draws many participants every year, and we have a low-income ecovillage with dorm accommodation in addition to apartments that come with gardening space. I have read that the increase in gardening is not confined to Portland, and concerning the vegetarian, vegan, and raw-food pattern, that is not limited to here either.

U.S. habits could change in the direction of less consumption, both from necessity and from choice.

A local realtor tells me that that is what the people moving here want. They want to walk wherever they are going in five minutes, as opposed to the car-commutes they are escaping.

This past weekend at a Community-Supported Kitchen meal, I met a medical doctor who recently moved here from LA for exactly that ability to walk or bike where she wants to go.

It is hard to predict what will happen next with the economy as it is.

Necessity could require what some are choosing. If that comes to pass, there are pioneers doing things differently from their own previous habits and from those of the generations before them.

Simply wonderful news all around, from India to Kenya to the U.S. I too have witnessed what appears to be a trend toward a level of personal awareness in the U.S. which says, "Less time in the car, more time on foot".

In Kenya, I can attest to the benefits of solar powered lighting as a direct means of reducing the use of non-renewable, often toxic sources of light such as wood and coal.

In 2008 I installed (and in 2009 upgraded) a small off-grid solar PV system for a rural school in Kenya, just outside of Nakuru:

The issue of battery replacement aside (which is improving with time), self-contained, self-sustaining power makes a lot of sense.

When you think about it, if someone forced us to sit in a confined space, trying to go somewhere but stuck, we would consider it to be a punishment. Amazing how so many put up with it (ok, including me from time to time, probably today on the way to a band gig).

Changing times are provoking re-thinking of so much that has been taken for granted. I am astonished by the resourceful people who do everything with their bikes. I appreciate their courage and good health when they pass a stuck me.

Then there are the runners.

I am working up my courage to join them.

Kai,

Technically wood is renewable, it does afterall grow on trees.
When burnt it only releases the carbon it absorbed through photosynthesis during its lifetime.
Of course if we burnt all the tree's to power our homes, we'd run out of tree's Real Quick!.
The forestry industry is the only industry that absorbs (and locks away in timber products) more carbon than it ommits.

Quite Interesting stuff really, considering that a lot of the supposedly enviromentaly friendly homes seem to be made from steel, which is refined from its ore in a high energy(usually coal fired) blast furnaces or similar. I assume these homes would be harder to insulate too, due to metals high thermal conductivity.

Mary,

Why not get a small battery bank, it sounds like you dont use much more electricity than your average kenyan villager anyway, so the cost shouldn't be too high. That way you wouldn't have to pay high service charges to stay connected to the grid dispite your low usage, which would offset the cost of installing and maintaining the batteries. Of course the grid is the best way of sharing our energy, renewable or otherwise, between the greater community, but theres something cool about being "off the grid" and completely independent.

My neighbors' tree blocks too much sun for me to do photo-voltaic now. The tree is ancient and well past its estimated lifetime, so the situation could change. What I need more than electricity is heat for the winter. I get some sun on the roof. Evacuated-tube water heat might work, but I have not explored it in detail yet.

These examples are good to hear. The use of solar power in remote areas is the best way to bring electricity to people. It is an advantage for these people to start with clean, fuel free electricity instead of copying outdated methods, of expensive and polluting energy systems. We take the electric grid for granted in this country because it was established so long ago, but running new lines for many miles in mountainous terrain would be very expensive. The loss of power from long transmission lines can cancel large percentages of the power produced. The modern batteries are maintenance free and can last over 10 years, my truck battery is now 10 years old and still good. There is no need to avoid batteries. Self produced power is a local investment that represents freedom and growth potential. The reduction in the use of kerosene and paraffin and wood will be a noticeable improvement in indoor air quality. They will probably do a better job of prioritizing electricity usage since they are not accustomed to electric devices for everything. This is one of those times where joining the market late is a big advantage over being invested in old and disagreeable technology.
