Scenarios and strategies for Africa

As this report from the Intertnational Renewable Energy Agency notes at the beginning, Africa makes up 15% of the global population but has only 5% of the global energy usage.  The worry for analysts and policy makers is that as the population of Africa increases, and development brings African energy usage to a level comparable to the rest of the world ...

New fuels for transport: the cost of renewable solutions

Although there is a great deal of focus on using renewable energy to replace grid power systems, there has been less analysis on renewable energy usage for the transport sector.  This cost report from  the International Renewable Energy Agency provides an outlook on decarbonising this important sector by 2020.  The report focuses primarily on  biofuel and electric, battery-powered vehicles.

A new open sourced grain drying technology in East Africa

A new open source grain drying technology dubbed the EasyDry M500, has been developed in East Africa, to help small holder farmers dry grains effectively and quickly, to reduce post harvest losses. The portable dryer, dries 500 kilograms of maize in 3 hours, by lowering the moisture content from 20 to 13.5 percent, the recommended moisture content level, for maize storage.

Water conservation technology helps fight food insecurity in Northern Ghana

In Northern Upper East Ghana, a water conservation technology is enabling about 400 smallholder farmers from 10 communities to farm in dry seasons.  As a result they are now getting at least two crop seasons annually as opposed to one, after implementing the PAVE irrigation Technology which harvests flood and rain water, and stores it in underground aquifers where it lasts for up to 180 days.

Pico-hydro a new source of energy in Rwanda

In Rwanda, a ‘Pico-hydro’ refers to a power system with a capacity less than 50kW. Their advantage over other power systems is their cost-effectiveness and simplicity, and come in different designs, planning and installation processes. It is an economical source of power that has proven useful in delivering clean energy to some of the world’s poorest and most remote places.

Solar milling machine to ease grinding systems

Whether they are consumed as grains or flour they are always products in high demand in Africa - these being cereals such maize, sorghum, millet and wheat. One of the issues with these widely consumed crops is when people want to grind them and consume them as flour, with most remote areas lacking access to electricity and therefore use expensive fossil fuel to run milling machines.

Earthen floors can really make it in Rwanda!

Better housing is one of the key indicators of the economic development, but most developing countries still have a challenge to secure clean homes for their habitants. Dirt floors are often responsible up to 80 percent of diseases. In most cases, parasites live in soil in form of feces and bacteria that can be contagious by either absorption or a simple contact. EarthEnable has introduced a solution to all those problems.

Croton plant offers some hope for biofuel enthusiasts

The Croton tree, which is commonly known as Mukinduri in Eastern and Central part of Kenya, is now a good known source of biofuels and that is being practiced. It grows in a challenging environment and unlike jatropha and palm, it won't bring food and fuel competition. It has no chemical additives and burns cleaner than traditional diesel fuel, with no sulfuric content. It can save our environment from carbon emissions and help in better land usage.

Using lean data to improve the solar power sector

Many companies use traditional methods to measure the impact of solar power investments such as quoting the many dollars invested, number of people using their kits and areas covered by their product, which are inadequate tools for measuring social impact for solar power investments if we have to get it right. Traditional approaches of gathering data are not only expensive, take time to give results and complicated to use, but are also not helpful in terms of boosting solar power funding. The lean data approach proposed by Acumen could, not only bridge solar power funding gaps in developing worlds, but will also help companies to understand emerging markets.
