A net-zero apartment complex was recently opened in Brighton Beach, Brooklyn, NY. The construction of this sustainable building was put on hold by hurricane Sandy, which hit when the building was already under construction. According to Robert Scarano, the architect who designed the Bright ’n Green project, as it is called, did not suffer major damage, and the net-zero building was able to supply power to the neighborhood via extension cords during the aftermath of Sandy.

A team of researchers at the Ohio State University (OSU) successfully produced a dye-sensitized solar cell, which can store power by using air to decompose and re-form lithium peroxide. This device combines a solar cell and battery into one, and it is the first device of its kind. The adoption of this technology could also considerably lower the costs of solar cells.

Harvesting solar energy is a great way to generate sustainable power, but unfortunately solar cells are far from being as efficient as they might be. Currently, commercially available solar cells can convert about 25 percent of sunlight into electricity, and scientists have been trying to create better solar cells for years. One milestone they have been unsuccessfully trying to reach is 50 percent conversion efficiency of solar cells. However, the start-up company Semprius might be on the right track with the stacking technique of solar cells they recently developed.

Two Russian scientists, Leonid and Sergey Plekhanov, both of the Moscow Institute of Physics and Technology (MIPT) are trying to crowdfund the building of a prototype of Nikola Tesla’s Wardenclyffe tower, which could allow for wireless transmission of power. Should they succeed, it is conceivable that the entire planet could be powered by renewable energy sources with very little energy loss during transmission.
