Since we often think of the move to clean energy as a “race”, I thought a fun way to do it would be to have the two best distance running countries in the world – Ethiopia and Kenya – square off against each other. Lets see how they are going when it comes to the clean energy race.
I was the community manager of the Global CCS Institute for over three years. I have to admit, that I didn't know much about the technology when I started but as a pragmatic green nerd, the general concept appealed to me. The truth is that there are thousands of coal fired power plants around the world right now ...
As shown in this report from the United States Department of Energy (DOE), 2014 was a big year for solar energy. Some of the most innovative concentrating solar power (CSP) projects in the world came online in 2013 and became fully operational in 2014.
After six years working on VideoSift, I've seen many excellent public service announcements (PSAs) for environmental causes. You might not think that a simple commercial spot has much to do with Cleanleaps, and yes, they sometimes can be self-serving, bordering on greenwashing ...
Hydropower or hydroelectricity is an established renewable energy technology that also may be quite low-cost. Although hydropower requires a steep investment to develop, dams in particular have a long lifespan and generally can produce consistent power over many decades. Consider that the Hoover Dam in the US Southwest has been in service since 1935 ...
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.
One of the most exciting ventures a country and its cities can undergo is that of modernizing and redeveloping its buildings. The progress made is almost always positive, and literally can give cities a new face. Major infrastructure projects in Vietnam are not so slowly transforming the city for the better, upgrading various aspects ranging from transportation to water treatment and infrastructure.
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.
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.
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.
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.
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.
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.
Research undertaken by Greentech Media (GTM) predicts that over the next five years, the global solar market will demonstrate a cumulative average growth rate of around 8%, with emerging economies including India and Latin America leading the progress.
