Thin-layer Solar Cells May Bring Cheaper Green Power
Scientists are researching new ways of harnessing the sun's rays which could eventually make it cheaper for people to use solar energy to power their homes.
Solar Energy Could Generate 2.5 Percent Of World Electricity
Oslo, Norway (AHN) - A report by the European Photovoltaic Industry Association and Greenpeace revealed that solar energy could generate 2.5 percent of the world's electricity by 2025.
The cost of a solar panel is determined in part by the size (in Watts), the physical size, the brand, the durability / longevity (or warranty period) and any certifications the solar panel might have. Choosing a solar panel on price alone is not wise, as it may not fit the area you wish to install it, may not have the necessary certifications to qualify for government rebates, or may not have the warranty required for economic payback of the power produced.
The traditional fossil fuels such as coal and oil are composed of much more complex molecules, with a higher carbon ratio and higher nitrogen and sulfur contents. This means that when combusted, coal and oil release higher levels of harmful emissions, including a higher ratio of carbon emissions, nitrogen oxides (NOx), and sulfur dioxide (SO2). Coal and fuel oil also release ash particles into the environment, substances that do not burn but instead are carried into the atmosphere and contribute to pollution.
