Natural carbon sinks work by the absorption of carbon dioxide by the oceans via physicochemical and biological process or via photosynthesis by terrestrial plants. Therefor natural carbon sinks include forests and vegetation, soil, atmosphere and oceans. Carbon moves between them in a continuous cycle. Land-use changes and burning fossil fuels such as coal and oil are major sources of carbon. Coal contributes the largest share of CO2. In the last ten years, China has overtaking other regions such as the US and the EU and is now the largest emitter. This is a cool world view map from the global carbon atlas shows exactly where most carbon emission are emitted. Still, when considering the amount of emission per capita, the US is still leading by a fair margin. Farming is also contributing a lot as a carbon source – improvements in farming practices could help to reverse this. Read moreTags: carbon sinks, Climate change, Kyoto Protocol
REN21’s December newsletter is now available. In it you can find out what is happening at REN21 as well as new initiatives, publication and upcoming event posted by its members. REN21 is also collecting data for its Renewables Global Status Report. The 2014 report will also feature a chapter on distributed renewable energy in developing countries.

A Kenya based company that distributes solar irrigation kits to local farmers could transform agriculture through solar powered irrigation – a cost-effective solution to low rainfall and spiking energy prices. GVEP is working with SunCulture to provide strategic advice on expansion into new markets.
SunCulture’s AgroSolar Irrigation Kit is a solar powered drip-irrigation system, designed to benefit those who live in arid and semi-arid areas. The SunCulture AgroSolar Irrigation Kit combines cost-effective solar pumping technology with a high-efficiency drip irrigation system which makes it cheaper and easier for farmers to grow fresh fruits and vegetables. The pump allows farmers to pull water from a variety of water sources, including groundwater and lakes, using solar power. Water is then pumped into a raised storage tank during the day, enabling irrigation to take place during the evening. SunCulture’s solar-powered drip irrigation systems deliver water directly to crop roots, resulting in yield gains of up to 300% and water savings of up to 80%.

Some recent news regarding the development of windpower in the UK were quite frustraing for the clean energy community – for example the the fact that big six energy companies have pulled the plug on one of the world’s largest offshore windfarms.
After RWE shelved its £4bn Atlantic Array windfarm warnings become louder that inconsistent messages from the government are actually undermining efforts to raise money for the sector.
While Britain could be a world leader in wind energy it has instead fallen to eighth place in the world in terms of wind generation capacity installed. Among EU member states it ranks ninth in the proportion of electricity generated from wind: 4.5% compared with an EU average of 6.3%. Read moreTags: clean energy, subsidies, UK, wind, wind power
REN21 is gearing up for its participation at the climate change talks in Warsaw. While climate is not a central theme to REN21′s work, renewables should be a central element of any climate action plan.
Despite tremendous growth in renewable energy witnessed over the last decade, fossil fuels continue to be a destructive force on our environment and the chief contributor to global climate change. Fossil fuel combustion currently accounts for nearly 70 percent of all carbon dioxide (CO2) emissions, two-thirds of which come from the energy sector. Although renewables accounted for 19 percent of global energy consumption in 2011, new estimates for CO2 emissions from traditional fossil fuels reveal a 1.4 percent increase, resulting in a record high of 31.6 gigatonnes (Gt).

A recent publication from the Global Alliance for Clean Cookstoves draws attention to the critical role that women play in scaling up the market for clean cooking solutions. GVEP’s experience in working with women-led businesses demonstrates that with the right support, tailored to their specific needs, the entrepreneurial spirit of women can be channelled into a thriving business.
In a newly published resource guide, The Global Alliance for Clean Cookstoves highlights the vital role that women play in scaling up the adoption of new clean cooking products and services, provided that a gender sensitive approach is used in integrating them in every step of the value chain. Their active participation to the business environment can in turn increase their bottom line, while providing health, environmental, and social impacts – state the authors.
