A study led by the Norwegian Institute for Nature Research observed a reduction of 71.9% of bird deaths from turbine collisions if one of the three blades was painted black. The study was conducted at the Smøla wind farm, along the West Norwegian coast.

Bård Stokke, one of the study's lead authors, stated: "Our hope is therefore that these measures, given their positive effects on birds and the fact that they are relatively simple and low cost, will be used in future wind energy developments both in Norway and abroad."

Apple has announced the self-commitment to become a carbon-neutral company for all products it produces and its supply chain, stating that the company is already carbon neutral worldwide in regards to its corporate emissions.

The communicated date to hit the goals is 2030 and Apple aims to achieve this by reducing its emissions by 75 percent and in addition using technology to remove carbon from the environment. These "innovative carbon removal solutions" will be developed by Apple themselves with the aim to close the remaining 25 percent of carbons.

Apple CEO Tim Cook has stated that "climate action can be the foundation for a new era of innovative potential, job creation, and durable economic growth. With our commitment to carbon neutrality, we hope to be a ripple in the pond that creates a much larger change".

The city of Sydney has announced that it has begun switching 100% of the electricity for the city to energy from renewable sources. According to the official announcement on the cities website they struck a deal to purchase energy from three different generators in New South Wales that is equivalent to 100% of the city's usage. The electricity comes in 3/4 from wind generation and 1/4 from solar generation and will be added to the electricity grid of the city.

Since the 1st of July, the city has started getting electricity from these generators with the aim of completing the switch to getting 100% of the cities electricity from these sources in 2021.

The Ethiopian Minister of Water, Irrigation and Energy Dr. Seleshi Bekele has announced that the country has started filling the Grand Ethiopian Renaissance Dam. He later stated on his Twitter account that "The inflow into the reservoir due to heavy rain fall and runoff exceeded the outflow and created natural pooling.This continues until overflow is triggered soon".

Talks between Egypt, Ethiopia and Sudan had ended with no agreement as Ethiopia aims to become a large energy supplier for its' population and generate revenue by exporting the surplus, while Egypt fears that the Nile will provide too little water for the country.
