From escalating cost of oil and natural gas to the melting of ice cap, the world is seeking information for renewable energy which is durable and adds less or better no pollution component to atmosphere. Many alternative solutions have been introduced such as wind power, thermal energy and solar energy. The nuclear power is often considered as an alternative energy because it provides energy with a very cheap cost. And also nuclear generation does not produce carbon dioxide, sulphur dioxide, nitrogen oxide, mercury and other pollutants associated with the combustion of fossil fuels. But the more severe is the unsolved problem of storing radioactive waste. I’m interested the most in solar energy because of the strong potential of the source –the sun- which pours everyday a huge amount of energy and produce it for free. Although this advantage, the grand barrier is the expensive price. The article “Nanocrystals enhance photovoltaics” at the first sight attracted me with the new method to fabrication the solar cell which is cheaper and easier when we compare with the traditional method. Under this condition, the new solar cell cost would be reduced. A cheap price of solar cell would attract the consumer not only in commercial use but also residential use. The residents who live in the area no access to electricity would then have electricity to use as the people who live in the urban. No production of polluted gas, we would then live in an intact environment which is good for us and also for our next generations.


Thank you for every comment :)

Many alternative solutions have been introduced, such as wind power, thermal energy and solar energy. The Nuclear power is often considered as an alternative energy because it provides energy with a very low/cheap cost. And also nuclear generation does not produce carbon dioxide, sulphur dioxide, nitrogen oxide, mercury and other pollutants associated with the combustion of fossil fuels. But the more severe is the unsolved problem of storing radioactive waste. I’m interested the most in solar energy because of the strong potential of the source –the sun- which every day pours a huge amount of energy and produces it for free. Although this is an advantage, there is a grand barrier: the expensive price of harnessing solar energy. The article “Nanocrystals enhance photovoltaics,” at the first sight, attracted me with the new method to fabrication of fabricating the solar cell which is cheaper and easier when we compare it with the traditional method. Under this condition, the new solar cell cost would be reduced. A cheap price of solar cell would attract the consumer not only in commercial use but also residential use. The Residents who live in the areas with no access to electricity would then have electricity to use as do the people who live in the urban areas.
