Renewable energy is the cleanest and inexhaustible source of energy. They are environment-friendly and help us tackle the most important concern of the 21st Century - Climate Change. Solar is one of the most important forms of renewable energy. Though solar cells are not efficient when it comes to producing energy during rainy seasons. Scientists from the University of Soochow, China have overcome the design flaw of solar cells.
Addressing climate change requires massive decarbonisation of our economy, particularly in areas such as electricity generation, transportation and agriculture. We focus on sharing knowledge on solutions to the problem as opposed to just forming the case for action.
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.
Wind energy is rapidly expanding, and the many benefits of wind power over other types of energy explain why. Let’s get a big picture look at wind energy before outlining why wind power is, frankly, better than the alternatives, including other types of alternative energy.
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.
About 8.2 million trees were cut down for charcoal in Somalia between 2011 and 2017, globally 50.8 tons of charcoal were produced, with Rwanda ranked at the 73th position with 48,000 tons. Thankfully there are still ways to remedy forest degradation by providing alternative, innovative and clean solutions for fuel - biomass pellets.
Climate change adaptation costs in developing countries could rise as high as US$250-500 billion per year by 2050 according to UNEP. With the world grappling with climate change, we need sustainable solutions to save our precious planet. Air pollution, deforestation and contaminated waterways are major issues, and there is a lot of work to be done in these sectors.
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.
The global transportation sector will welcome twice more cars by 2030. Additionally, global freight volume will grow by 70 percent compared to 2015 figure. This is even as high population growth and faster urbanization trends push high the demand for connectivity. What cleaner and greener mobility options do we have today to save our environment tomorrow?
