Advantages And Disadvantages Of Solar Technology

1213 Words5 Pages

2.1. Solar energy
Previous studies mostly defined solar energy as a free and somewhat accessible in various part of the world. Compared with different energy sources, such as nuclear and fossil fuels, scientists claim that significantly energy can be provided for earth by sun radiations. The effectiveness of the solar energy application in various technologies can be exemplified as follows:
• Photovoltaic (PV) technology which light can be directly changed into electricity.
• Solar–thermal systems which solar collectors utilize.
• Artificial photosynthesis which is being used for delivering carbohydrates or hydrogen via water splitting.
• Passive solar technologies which are installed in buildings for improving solar lighting and heating.
• Biomass …show more content…

It is worth to mention that nowadays more than 13% of total world’s primary energies are being provided from biomass technology. There are a number of significant differences between biomass and solar photovoltaic (PV) technologies. For instance, biomass productions have lower energy density and conversion percentage. On the other hand, capability of storing solar energy for practical usage can be mentioned as an advantageous of biomass compared to (PV). In the following pages, improvements of novel photoactive substances for altering sunlight to electricity will be discussed carefully. Moreover, nowadays self-cleaning areas are another significant aspect of developing solar thermal systems. The methodology is similar to procedure which solar radiation is considered for heating buildings by providing hot …show more content…

Many experiments have been suggested that improving quantum-based instruments, such as quantum dots and quantum wires, has significant positive results for space industries. These days, solar cells which are based on nanocrystalline quantum dots are more prevalent because not only operate at more efficiency, but also cheaper compared to silicon-based solar cells. It is worth to mention that nowadays the application of conventional silicon-based solar cells is reduced drastically because increasing the cost of silicon can give rise to generating solar-based electricity price, which should be lower than 1

  • What Are The Pros And Cons Of Nuclear Energy

    Nuclear energy has numerous world benefits that other forms of energy creation just don’t, and its pros are truly unprecedented by any other source of energy. Nuclear power plants are inexpensive to run, which means they can easily be maintained and sustained at a low cost. And while the reactors themselves may be expensive, with government grants the materials can be much more easily purchased and built. The most expensive part of the nuclear reactor process is the uranium, which again, isn’t hard to get as it’s used in few other applications and can be acquired through government programs. Additionally, the energy emitted from these power plants compared to their cost is immense and an extremely worthwhile investment for governments and private businesses.

Years After it was discovered that if strontium 90 was removed and exposed to sunlight, it would continue to work on solar all by itself. Back to harnessing the sun 's light Bell labs could only find a place for solar technology in a small variety of toys. With almost all enthusiasm gone from solar technology, Bell Labs needed something new. After months of discussion with top-level power experts the scientists conclude that artificial satellites would be in the perfect conditions for solar energy to

    Scientists have found that renewable energy is a path towards the future for a clean and safe environment. Throughout all the studies and findings, there is a continuing fret whether people should be able to use a traditional way of energy or renewable energy, solar power. Solar energy is seen to be effective since there has progressively been more places that are benefiting from solar usage; however there are also some who disagree. Solar energy sources are derived from natural sources and is implicated throughout our daily lives. From the lights in the streets to the computers we use at home.

    wind energy and solar energy are both renewable types of energy they create no pollution and are fully sustainable as they are both powered by natural sources and if there is no wind one day the solar panels can generate energy and if it 's cloudy another day the windmills can generate energy also the energy created during the summer can be sold to the grid for extra capital that can be used for field trips, renovations, etc. Geothermal heating systems are rated the most efficient and eco-friendly heating systems. The system works using buried coils that contain a liquid, typically a mix of water and antifreeze. The liquid is warmed to the same temperature as the earth and then runs through to the home where a compressor extracts the heat but not only that geothermal heating requires no fossil fuels so it is very eco-friendly LED lighting is an efficient and eco friendly lighting alternative because they waste much less energy in converting to light compare to incandescent lights which waste 90% of the energy to convert to heat not only that LED lights last up to 15-25 times longer that traditional light bulbs this makes LED a much better source of lights than others because it wastes less energy and it is more efficient at doing its job this is so much better for the environment because it uses less energy that other lighting sources
