We all like to do our bit for the environment. We recycle, use kitchen waste to make compost, use reusable shopping bags, etc. These are all done in an attempt to decrease the usage of our planet’s resources and to reduce pollution. However, there might be more than you can do without even setting foot out of your home. When it comes to energy consumption, temperature regulation is one of the highest costs. We heat our homes in winter and cool them in summer.
More than 8 million people don’t have access to clean drinking water the world over; and more than 2 billion get their water from contaminated sources. Despite this problem, emerging technologies including solar powered purification systems are making it possible for emerging ecnomies to achieve cleaner drinking water.
Three young inventors from New Delhi, India have developed Chakr Shield; a technology that traps over 90 percent of pollutant suspended particulate matter (SPM) emissions from exhaust pipes of diesel generators. The SPM in form of soot (black carbon) is then recycled to make inks and paints.
The World Banks Lighting Global Program, Dalberg Advisors and GOGLA (Global Off Grid Lighting Association) have launched number four of its bi-annual publication – an in-depth analysis of the trends of the global off grid solar power market. The report examines an expanding market that is helping developing countries make a 'cleanleap' from fossil fuel based electricity to using renewable energy from the sun.
An underground irrigation technology has helped 100 farmers in Tunisia to continue farming in times of droughts. Dubbed the Buried Diffuser, the technology utilizes 2 times less irrigation water than drip irrigation, while raising yields 3 to 5 times more; and ensuring water is not lost through evaporation.
West Africa's largest healthcare project has been launched in Accra, Ghana. The Eco Medical Village is set to become a 1,100-bed sub-regional project, providing specialized medical centers across 40 acres. Offering African's an alternative to traveling to India, Europe or the US for their healthcare needs, it also keeps this valuable investment within West Africa.
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.
