A federal court in Washington, D.C. has struck down the Dakota Access Pipeline, following years of campaigning by the Standing Rock Sioux tribe.
World’s largest concentrated solar power plant now operational
With a capacity of 392 megawatts, the Ivanpah concentrated solar power station has begun producing and providing energy.
The Ivanpah Solar Electric Generating System, set up in the California Mojave Desert, is the world’s largest concentrated solar thermal power station, and started delivering solar electricity on 13 February. At full capacity, the facility produces 392 megawatts (MW) of solar power, enough electricity to provide 140,000 California homes with clean energy and avoid 400,000 metric tons of carbon dioxide per year, equal to removing 72,000 vehicles off the road.
Here are the figures that made the Californian facility the world’s biggest concentrated solar power plant:
- 173,500 heliostats, solar mirrors that follow the sun trajectory all day;
- the central tower is 137 metres tall;
- 14 square km surface;
- 3,000 site workers employed;
- 8.35 million man-hours completed;
- 650 million dollars (475 million euros) in salaries for construction and operations is expected to be paid over the next 30 years.
The Californian concentrated solar power plant, whose construction works started in October 2010, is a joint effort between three large American companies: Nrg, Brightsource energy and Google. The project received a 1.6 billion dollars loan guarantee from the US Department of Energy’s Loan Programs Office.
Here’s a photo gallery with stunning images of the facility:
The Scottish island of Eigg is self-sufficient for its energy needs, relying almost entirely on renewable sources, especially thanks to a coordinated community effort.

A large dam along the Luangwa River in Zambia would have posed a serious risk to local people and wildlife, leading hundreds of thousands to oppose it. A call to which the government responded by halting plans to build it.
The first one megawatt solar power plant in the Chernobyl exclusion zone has become operational. This is the first step in a renewable energy development project promoted by the Ukrainian government in the area.
Gas explosions are frequent in Nigeria, where safety standards are poor. In the latest incident, a gas tanker blast killed 35 people in Nasarawa state.
The largest tidal power plant in the world will be built in the Larantuka Straits. It will serve 100,000 people and help overcome some of the challenges of energy provision in Indonesia.
Robben Island’s solar energy micro-grid project will produce almost one million kilowatt hours of electricity annually, significantly reducing the cost and impact of buying diesel.
The Balikpapan oil spill off the coast or Borneo in Indonesia covers 120 square kilometres. It has caused the death of 5 people, health and economic problems for local communities, as well as threatening wildlife and local ecosystems.
