In recent years, there has been renewed interest in biomass energy in Africa, primarily due to growing environmental crisis, energy security concerns and rapid increase in fossil fuel prices. Africa’s convertible currency earnings are very low due to poor world market prices and decreased volumes of its commodity exports. Consequently, it is estimated that, petroleum imports as […]
Application of solar energy systems in building design saves money and conserves energy, in addition to attractive architectural designs and improving environmental conditions surrounding the building. Passive solar technologies and PV systems can be effectively used making a building sustainable. Passive Solar Design Passive solar technologies directly take advantage of the sun’s light and heat […]
Passive solar design is a method to collect solar energy using windows, walls, floors etc. and distribute it to the room during winters to maintain considerably high temperature than outside or reject it to maintain inside temperature considerably cool during summer thus providing a natural air-conditioning system. The system does not require any mechanical or […]
The concept of sustainable building was started during 17th century when Greeks developed technological innovations for passive solar design so that every home can avail solar heat during winters. A sustainable building is designed, renovated, operated or reused in an ecological and resource efficient way without compromising with needs of future generation and reduce negative impacts […]
Winter is coming and with it, higher fuel consumption. You’ll need to crank up your boiler to combat colder temperature and turn on lights earlier to chase away the 4pm dark. And you know, plug in that electric blanket, take warm showers, and put the kettle on all the time. Keeping hygge—or just warm—in the […]
Wind energy is one of the major clean energy sources, though largely untapped in many parts of the world. Wind is also a form of solar energy, since generation of wind is based on solar energy. Uneven heating of earth, irregularities on earth’s surface and earth rotation causes wind to generate. Wind power is the […]
Generation of energy using ocean water currents is one of the most important yet unexplored and neglected topic. Water current turbines are energy contributors which can reduce conventional energy dependency and decrease dependence on conventional fossil fuels in the country. In case of water current turbines, issue of space comes nowhere, what matters is the […]
