Solar energy and ‘going green’ are getting a lot of attention these days. Many people are talking about thin film solar cells, also called solar film. This article will give you a rundown on the various technologies out there, without getting too deep into the chemistry and physics of how they work.
Solar film cells are getting a lot of attention because they address the biggest issue with solar energy: cost. The development of this technology has take great strides in recent years because they are cheaper to manufacture than traditional solar panels. Thin film solar panels are what you would find in a solar calculator, and this technology is being expanded into panels for large residential and commercial use. Global Solar Energy, for example, recently installed a 750 kilowatt array that provides 25% of factory’s power needs.

Natural gas and electricity are the two most common providers of heat and light in today’s homes. These two commodities have been around so long it is difficult to imagine a world where they are replaced with an alternative.
So far as we can see, on the scientific horizon at least, they wont be replaced either by some such method as zero point energy, which is energy created by the mechanical oscillations of quantum particles…Sound like science fiction ? Well, so far, yes it is still in the realms of science fiction and if it were possible today, would be hugely expensive to produce. But don’t despair, because In 1989 two chemists, Pons and Flieschman conducted an experiment and claimed to have determined a process of cold fusion. Fusion is a process that happens in the heart of stars, while fission is something that occurs in nuclear reactors. Both very big and at least one, very expensive! Neither a viable option for sole domestic use.

Coral triangle is the most diverse marine environment in the world. It covers more than 5.4 million square kilometers, with over 600 reef-building coral species which encompasses 75 percent of all species known in the world. This area is not only rich with corals but also with fish as there are more than 3,000 species of fish live in the Coral Triangle, including the largest fish – the whale shark. But this area of extremely rich biodiversity is under great jeopardy of being destroyed by the end of the century unless world makes quick action to tackle climate change and global warming.

Apart from the great financial impacts, the human impact is being already felt. Millions are starving throughout the globe, and with the World’s population is rising steadily, the situation will only continue to deteriorate if temperature and climate is allowed to continue unimpeded.
To understand how mankind can counter global warming, we must understand what brought it about. There are several holes in the ozone layer, caused by gases emitted from the Earth’s atmosphere and rising into the atmosphere. These gases have been caused by the use of certain noxious chemicals, some of which were used in agricultural. One of them in particular, Methyl Bromide, has largely been banned from use. Another minor cause in temperature and climate changes is the use of aerosol sprays, which might seem petty and innocuous, has had some effect, scientist say. However the principal gases being emitted into the atmosphere are from industry and vehicle exhaust systems.
