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 ...
The Global Cleantech 100, now in its 6th year released by the Cleantech Group, is a list of the top companies in this space worldwide. The Cleantech 100 is no longer just a list of companies from places like the United States, Germany and Japan. Emerging markets are seeing the benefits of clean technology and some of the leading companies in the world are starting to come from emerging markets like Kenya
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 ...
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.
Nationally appropriate Mitigation Actions or NAMAs for short are a relatively new policy tool championed by the International Renwable Energy Angency from within the UNFCC. The key concept behind NAMAs are that a single climate change mitigation policy is not appropriate for all countries.
At least one in ten girls in Sub-Saharan Africa misses school during their menstrual cycle. So, women suffer a lot from this situation, and it affects most of them in the rural area who cannot go to school or afraid to do any other type of work in public during the menstruation period and are forced to isolate themselves. A way to combat this has been using the agricultural waste from banana trunk fibres which is a cost-effective way to make sanitary products.
The United Nations Environment Programme in collaboration with Bloomberg New Energy Finance released their annual Global Trends in Renewable Energy Investment 2018. The report focuses on investment in renewable power and fuels - wind, solar, biomass and waste, biofuels, geothermal and marine projects, and small hydro-electric dams. The rise of solar power has dominated renewable energy investment in 2017, more than that new coal, gas and nuclear plants put together.
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.
