Once installed‚ energy is free Fourteen solar farms have a combined installed capacity of 388.4 megawatts and in 2011 generated 0.1 billion kilowatt-hours. (Source: Canadian Centre for Energy Information compilation‚ 2013) There are now 3‚133 megawatts of solar power installed in the U.S. That’s enough to power nearly 3 million homes. The average cost

Green‚ Just Do It Some people might hear the term “Going Green” and think of some big green monster running around destroying buildings. But really all it means is conserving energy and in the end help make the world a better place. This term “Going Green” is used a lot in today’s society‚ but rarely do you ever see people doing anything to help and going green isn’t as difficult as it seems. But if nothing is done now the future of Earth will be dramatically affected by it. Not many people realize

matter and energy cycle throughout systems. The cycling throughout networks can be explained by the Law of Conservation of Matter and Energy‚ which states that matter and energy cannot be created or destroyed‚ only changed. This cycle applies to many things‚ such as energy cycling through a food web‚ carbon traveling through the biosphere in the carbon cycle‚ and the movement of energy and materials that are used during photosynthesis and cellular respiration. The cycling of matter and energy is essential

Direct energy conversion system Direct energy conversion systems that could operate in the 100-700°C temperature range with high efficiencies (>30%) provide an attractive compact alternative to internal combustion engines for many military applications. They will also expand the possibilities for waste heat recovery applications. The core of the solution we are proposing is a metal/semiconductor nanocomposite that will allow us to modify four intrinsic material properties in order to fabricate

Pak-Iran gas pipeline Pak-Iran gas pipeline project - which would essentially change the face of the ongoing energy crisis in Pakistan for the foreseeable future – seems to be ending in despair. Initially‚ the project too included India. However‚ India dropped out along the way since the negotiations commenced nearly two decades ago. Now‚ there are again reports doing round in media‚ reporting Indian Minister of External Affairs Salman Khurshid‚ that India might renter negotiations over the IP gas

Many people have come to realize the dangers of light pollution outdoors‚ but the light pollution problems are often not enough paid attention to indoor environment. In fact‚ the poorly designed interior lighting will cause a certain degree of light pollution‚ affecting the lives of the occupants health. The Indoor light pollution is caused by many reasons‚ but what are the reasons in terms of the lighting design? We asked the Beijing lighting design Tomomi’s chief designer Ren Jian‚ he said:

to have an ever-increasing need for more energy. Both households and industries require large amounts of power. At the same time our means of production face new problems. International treaties aim to limit the levels of pollution‚ global warming prompts action to reduce the output of carbon dioxide and several countries have decided to decommission old nuclear power plants and not build new ones. Such development brings about the need to replace old energy production methods with new ones. While
