Due to the predictions of the depletion of oil in the near future, many countries start to depend on renewable energy sources. Since solar power is one of the best choices, many massive solar energy projects have been established. Whiticar et al. state some examples of enormous solar power projects. Firstly, the largest project is SEGS, located in Modjave Desert in U.S., which uses solar thermal technology to produce enough electricity for half-million people.
They use an array of solar photovoltaic (PV) cells (or modules made of cells) that convert sunlight into electricity. The electricity either goes directly to an electric motor powering the vehicle, or to a special storage battery. The PV array can be built (integrated) onto the vehicle body itself, or fixed on a building or a vehicle shelter to charge an electric vehicle (EV) battery when it is parked. (Green nature) Next, “Hydroelectric power is the largest source of renewable ... ... middle of paper ... ...,000 light bulbs that use 100 watts (Energy Story) Even though you can only use windmills in areas that are fairly windy they are still an effective way to produce without burning fossil fuels. Luckily, there are many means alternative energy sources to conserve the earth's limited natural resources.
The main reason solar energy is getting so big is because of the advantages of the use of solar energy. The main advantage of solar energy is that the power source is infinite unlike fossil fuels which are limited. Scientist currently predicts that in the next forty to fifty years fossils fuels will expire. Also solar energy is cleaner, rather than fossil fuels, solar energy doesn’t give off pollution and also is water efficient. Nuclear power plants and gas power plants use up so much water to cool the plant down, solar panels however doesn’t need water for anything.
This shows the underutilized capacity of solar energy in attaining sustainable developments. The photovoltaic systems do not release greenhouse gases in the power generation process. Moreover, they can convert sunlight into electricity even in conditions of low solar energy. This proves that solar power can be available for use in domestic or commercial buildings even on cloudy days. In contrast, the indirect conversion of solar energy through CSP techniques involves the generation of heat energy and using the resultant steam to operate power generators (Hirschmann 36).
Nanotechnologies will help reduce weight of carbon emission in transportation utilizing nanocomposite materials that quickly diffuses across the automotive and aerospace industries. Applications of nanotechnologies will result in a global annual savings of 8000 tons of carbon dioxide, which will rise even further to over millions tons by 2020. But, let’s focus on the positive effects of Green Nanotechnology in Solar. Although Solar Energy is a flexible source of where energy could be directly or indirectly converted into forms of energy, it’s still not perfect. With its inefficiency, scientists are trying to find alternative solution to store solar cells for as long as possible.
The sun shines upon Earth every day, yet no one thinks much of it. Solar power’s importance, though, is above what anyone could have ever imagined. There is active solar energy, which is when solar power is converted into light, heat, cause air-movement for ventilation or cooling, or store heat for future use. Less thought of, the other type of solar energy is passive energy, which most take for granted. Solar power provides life with heat, light, and now, electricity.
Nearly all energy in one form or another can be traced back to solar energy, and it is harness in many different ways. Solar cells are the most direct way to convert incident solar radiation into electricity, this process is also known as photovoltaics. Solar cells produce no pollution, noise, and do not contain any moving parts, allowing them to be tough, reliable, and long lasting. The natural light that we enjoy from the sun and see every day is only a fraction of the total energy emitted by the sun incident on the earth. The visible portion of sunlight is from just a small portion of the electromagnetic spectrum.
Solar power is a relatively untapped power source which could contribute to solving the energy crisis. Solar power plants can operate as long as the sun continues to give off light and heat, and it will continue to do so for billions of years. However, solar power plants cannot be the only power source, for they do not operate at peak efficiency at night or when the sun is obscured by dense cloud cover. Solar power accounted for only 0.064% of US energy consumption in 2003, while fossil fuels accounted for 85.973%. Also, solar power production in the United States has been decreasing since 1996 (see Figure 1) (Annual Energy Review, 2003).
Solarroadways.com explains that even though solar roadways cost 70 dollars per square foot, unlike asphalt roads, solar roads are so efficient that, if installed nationwide, they would pay for themselves over the course of a year. Solar roads would convert the sun’s energy into electrical energy. The energy would be stored using “virtual storage", meaning that excess energy would be placed back into the grid during daylight hours and then could be drawn back out of the grid in the evening. The power generated by the solar roads is worth more than it would cost to replace our existing nationwide road infrastructure. In fact, according to Mr. Brusaw, a nationwide network of solar roads would generate over three times the electric power America consumes each year.
Therefore, with the use of solar energy, it will help keep the environment clean, thus help to combat the issue of global warming, which is a threat to the world’s ecosystem worldwide.

The sunlight and heat will always be available to us because, it is a non-extinguishing resource and so, let us make use of it. With all these points made, there is no question that, solar energy is capable of becoming the world's future power supply. Works Cited Venables, M.
