Solar Sunday is my weekly roundup of renewable energy and energy efficiency news from around the web.
Researchers have created a new material that overcomes two of the major obstacles to solar power: it absorbs all the energy contained in sunlight, and generates electrons in a way that makes them easier to capture.
When faced with the need to develop additional sources of energy, the Ethiopian Electric Power Corporation recently decided that its best option was not to build conventional power plants. Instead, the electricity provider opted to fulfill its energy needs by building Africa’s largest wind farm! The 120 megawatt Ashegoba plant in north Ethiopea will provide for 15 percent of the nation’s present energy capacity.
Currently slated for construction in Singapore, the EDITT Tower will be a paragon of “Ecological Design In The Tropics”. Designed by TR Hamzah & Yeang and sponsored by the National University of Singapore, the 26-story high-rise will boast photovoltaic panels, natural ventilation, and a biogas generation plant all wrapped within an insulating living wall that covers half of its surface area. The verdant skyscraper was designed to increase its location’s bio-diversity and rehabilitate the local ecosystem in Singapore’s ‘zeroculture’ metropolis.Approximately half of the surface area of the EDITT Tower will be wrapped in organic local vegetation, and passive architecture will allow for natural ventilation. Publicly accessible ramps will connect upper floors to the street level lined in shops, restaurants and plant life. The building has also been designed for future adaptability, with many walls and floors that can be moved or removed. In a city known for its downpours, the building will collect rainwater and integrate a grey-water system for both plant irrigation and toilet flushing with an estimated 55% self-sufficiency.
855 square meters of photovoltaic panels will provide for 39.7% of the building’s energy needs, and plans also include the ability to convert sewage into biogas and fertilizer. The tower will be constructed using many recycled and recyclable materials, and a centralized recycling system will be accessible from each floor.
