The main purpose of green nanotechnology has been to develop clean technologies that would minimize potential human and environmental health risk. Also, to encourage replacement of existing products with the clean technologies that is more environmentally friendly. There are many benefits of using green nanotechnologies as the new solution for energy in both their current availability and their current development. Over the new few decades, the highest growth opportunities will come from application of nanomaterials for making better use of existing resources. 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 main process of capturing solar energy happens at the nanoscale. With solar cells, it gets more efficient the tinier it gets. The converting rate of solar energy is equally price competitive as fossil fuel, with a dollar per watt of solar energy. With the help of nanotechnology, it could help raise solar energy conversion efficiency and help lower costs making it the ultimate method of raw energy conversion. To make sure the process of generating energy is kept at a low cost and energy output... ... middle of paper ... ...n, Japan have been looking at new ways to improve their energy production. However, rather than using nanotechnology to absorb sunlight, their main focus is looking into the mechanics and possible machinery they can create through nanotech. Since development and invention takes time and money, some people question if it’s worth the effort. Some scientist are looking into another way for clean solution that doesn’t require as much funding and as much time. Nanotechnology is the answer for solar energy. With electrical device being used 24/7 and electricity on high demand, we need to constantly produce energy. Nanotechnology can help rise efficiency up to 40% which allows a normal panel module to produce around 30 watts per square foot. That’s 1.3 mWh for one acre. With this advancement in the process of development, soon there won’t be any energy crisis.
economically feasible, all of the research in the world will not make it happen. No matter how you look at it,
Preview: Today I will discuss the potential that solar power has to become this country’s main supply of energy and the latest research that can make solar power more efficient and cost effective. I will also present the environmental benefits that come with using solar power over other and more harmful forms of energy.
With a looming energy crisis and an unstoppable rapid decrease in fossil fuels, the need for renewable energy is greater than ever. Yet it is inevitable that with every new solution, there are consequences. People can only hope that the energy crisis will be resolved with every new and advanced generation of scientists.
A lot of scientists like the idea because it is advanced and they say it’s cleaner and safer in many

Solar is a viable alternative energy source with solar panels becoming more affordable and more efficiently designed.
Clean energy alternatives can be easily extracted from nature without causing harm to the environment. They are also renewable resources, so they can be replenished continuously.

...iest thing, human urine. It kind of makes sense. It’s easy to get and really cheap to make. It’s actually very inventive.one I never will understand is the BMW that runs on human poop.(www.alternative-energy-news.info) That’s a little too far if you ask me, but again it’s easy to find and really cheap to make and easy to produce. In fact they are focusing on a lot of fuel to come from waste. Whether it be from humans, animals, plants, or anything else in the environment. Thinking about it alternate energy will help us immensely in the long run, despite the costs. That’s only the beginning. After all the spending and installing we will save a lot more after than before.
(4) Based on this information, researchers try to utilize green energy, specifically solar energy as an alternative to fossil fuels in powering the planet. This is a step towards sustainability as they are using what’s already available (100,000 TW energy from the Sun) and trying to improve upon solar panels (make them cheaper). While the Earth’s current population require 17 TW energy on average each year, solar panels are costly. Suntech Power founder Shi Zhengrong is focusing on cutting the cost of solar by making them more efficient rather than perfecting solar panels. Moreover, Steven Chu, former U.S Secretary of Energy has increased spending on developing clean energy such as solar power, wind power and carbon capturing by US $40 billion. He wants to supply the world with such technology as other parts of the world (China, India and Western Europe) are already in the lead. (4)
Have you ever thought about helping the environment and make it healthy? Solar cars can save your money, help the environment and change the future transportation more easier. People call these cars their best friends because they use only the sun's energy to move. Solar cars are important these days because it’s a way to save money instead of paying for gasoline and it doesn’t harm the environment. You might think solar cars are really good and have really good advantages, but there is disadvantages with these types of cars too. Now lets begin.
Solar power utilizes the sun’s energy to produce electricity, unlike other sources of energy, which rely on continual mining for raw materials. Consequently, producing solar energy from the heat from the sun does not result in the annihilation of the ecosystem, compared to the extraction of fossil fuels (Bode, 2005). Therefore, with the use of solar energy, it will help keep the environment clean, thus helping to combat the issue of global warming, which is a threat to the world’s ecosystem worldwide. The use of solar energy will help save the worlds vegetation, and help prevent the effects of global warming in future.... ... middle of paper ...

Over the past decades, geologists and scientists alike have determined that the Earth is running out of non-renewable resources, particularly those resources that provide us with energy that fuels our world’s economies, jobs, and most importantly our daily lives. Without this energy, whole countries can collapse, and the human race would struggle to survive. Therefore, it is safe to assume that we as a nation are entirely dependent on energy, or the ability to do work (Gale Science in Context). Consequently, we are now actively searching for more cost efficient and useful forms of energy to replace those we currently use. By doing this we will be helping the earth by reducing carbon emissions and cutting down on air and water pollutants. This may ultimately prolong the life of our planet, and save money and resources while doing so.
Throughout the century researchers and scientists have looked for alternative fuel sources. Ranging from fossil fuel alternatives such as electric batteries, to wind energy, and even energy from the sun which is called solar energy. Solar energy dates back to the year 1767. It was created by a Swiss scientist named Horace-Benedict de Saussure. It was an insulated box covered with three layers of glass to collect heat energy. Saussure’s box was known as the first solar oven. Since that day solar energy has come very far. In 1958 solar energy flew to space. in 1981 the first solar aircraft was built followed by the first solar powered car in 1982. Finally in 1999 solar power was at its record peak, using the most efficient cells ever developed. But then in 2008 due to the financial crisis, Evergreen Solar and Solyndra Solar failed. With that said it still did not stop solar technologies from advancing.
