Biogas specialist acquires additional refineries

The Weltec Group has acquired two biomethane refineries in Hesse and Saxony-Anhalt in Germany. The plant in Hesse produces 1000 m³/h of raw biogas which it converts to 550 m³/h of biomethane.  This gas is then distributed on Germany’s public natural gas grid. In addition to the purchase of the biomethane refinery in Hesse, the company […]

Floating wind turbines and substation

  Fukushima Shinpuu, the largest floating offshore wind turbine in the world – with 7 MW output capacity – is moored off the Japanese coast near the port of Onahama. The rotor blades reach a height of 188,5 m and the hub is 105 m above the surface of the sea. It took five tug boats […]

Positive demand side management: balancing renewable energy sources

  Demand side management (DSM) is normally associated with encouraging or forcing a reduction in maximum demand to enable a constrained generation capacity to match demand. However, the introduction of variable renewable energy sources into many grids has resulted in times where generation capacity far exceeds demand for short periods, stressing the generation fleet as […]

Significant growth reported in renewable energy investment and usage

  Renewable energy continued to grow in 2014 against the backdrop of increasing global energy consumption, particularly in developing countries, and a dramatic decline in oil prices during the second half of the year. Despite rising energy use, for the first time in four decades, global carbon emissions associated with energy consumption remained stable in […]

The energy wars are over, and sustainability has won

  South Africa’s unique position in its electricity sector causes a fact not yet universally acknowledged to be increasingly self-evident to us: renewable energy is the way to go. It is cheap, clean and able to support a modern economy. It creates jobs, supports rural development, and is supremely compatible with long term sustainability (which in our […]

South African wind atlas launched

  Speaking at the launch of phase one of the wind atlas for South Africa (WASA) project, the Department of Energy’s Nomawethu Qase said that the report demonstrates that South Africa has sufficient wind resources for it to be a viable source of renewable energy. The event, which was hosted by the Department of Energy in […]

First half of 2015 sees huge cost savings from renewable energy

  A second independent study by the Council for Scientific and Industrial Research (CSIR) found that renewable energy from South Africa’s first wind and solar (photovoltaic) projects created R4-billion more financial benefits to the country than they cost during the first six months of 2015. The full presentation may be downloaded here The study is […]

Renewable energy platform for South Africa

  The International Renewable Energy Conference (IREC), a global platform for the advancement of renewable energy, is coming to South Africa. Hosted by the Department of Energy (DOE) in conjunction with the South African National Energy Development Institute (SANEDI) and the Renewable Energy Policy Network for the 21st Century (REN21), the South African International Renewable Energy […]
