Green Power from Clean Power Essay

Green Power from Clean Power Essay.

Green energy is energy that is produced in such a way as to minimize its negative impact on the environment. Traditional energy sources, most notably fossil fuels, produce greenhouse gases that are believed to be the primary cause of an effect known as global warming or climate change. Sources of green energy, such as solar, wind, geothermal, and hydro energy, are developed and promoted as alternative sources that make little or no contribution to climate change. Even nuclear energy is sometimes considered a green energy source, because some types of nuclear technology produce much less waste than oil and coal.

Why Green Energy is Important The industrial revolution that began in the second half of the 18th century changed the world, with new methods of machine-based manufacturing leading to a profound increase in economic growth, population growth, and quality of life. At the time, the long-term consequences could not even be conceived of, much less felt; however, the burning of vast quantities of fossil fuels, such as coal and oil, has caused a great deal of harm to the environment.

Most climatologists agree that the use of fossil fuels has contributed significantly to global warming.

This term refers to the measured increase in the Earth’s surface temperature since the late 19th century and the environmental effects of this change. The primary goal of developing green sources of energy is to generate power while minimizing both waste and pollution, to thereby reduce the impact of energy production on the environment. Scientists who advocate the use of green energy say that using such sources will reduce the rate at which climate change occurs, although it cannot stop or reverse the temperature increase. Another important objective is creating energy sources that are renewable.

This is in contrast to fossil fuel sources, which are finite and estimated to be depleted before the end of the 22nd century. Hydro Energy This technology uses the movement of water to power turbines attached to generators, and in many countries, it provides a larger proportion of energy than any other green resource. Hydropower does not produce a significant amount of waste and provides a unique environmental advantage. Many of the largest hydroelectric damns make use of a reservoir, which can serve as a location for recreational activities. The presence of a large water supply can also provide valuable support for agricultural regions.

In some cases, however, damming a river and creating an artificial lake can cause damage to the environment. Fish may not be able to make their way past the dam, for example, reducing their populations. Man-made reservoirs require flooding an area that was previously dry, changing it dramatically. The Three Gorges Dam in China offers a clear example of both: the baiji or Yangtze river dolphin, which lived in the river where the dam was built, is now functionally extinct, and over 1 million people were forced to relocate when their towns were covered in water to create the reservoir.

Solar Power Solar power does not produce any emissions, is renewable, and is highly suitable for powering portable devices as well as homes. Many new homes take solar energy generation into consideration as a design concept, with solar panels and water-heating systems. While the goal of solar-powered transport has not yet been achieved, the panels can be employed in vehicles as a source of power for air conditioning. When it comes to large-scale energy production, the main disadvantage of solar technology is that solar panels and energy storage devices use a significant amount of land.

This can be defrayed somewhat by building on land that is not suitable for other uses. Although the technology has improved, most are only about 20% efficient and can be expensive to install. Wind Power Wind is used to generate energy with large turbines connected to a power collection, storage, and distribution system. This type of energy generation is a highly effective method of providing electricity to small, isolated communities. They are often preferred over solar-powered methods in agricultural areas, because land which contains wind turbines is more easily able to be used for other purposes.

Off-shore wind farms have much higher building and maintenance costs, but they are able to harness stronger, more consistent winds. Because the turbines are large, some people complain that they are eyesores that distract from the beauty of the environment. There is also some concern that they could harm local bird and bat populations. Geothermal Energy Geothermal energy is generated by the earth underneath its surface in the form of heat. While it is not technically a renewable source, it is sustainable more or less indefinitely, and produces only a small amount of waste in comparison to fossil fuels.

Many countries use this type of energy for a portion of their requirements, but most thermal energy plants are located near tectonic plate boundaries, where the energy can be extracted more easily. The potential of geothermal energy to supply a significant portion of the world is limited by the expense of the technology it requires. Nuclear Energy Some types of nuclear energy are categorized as green because they produce very small amounts of waste. A green nuclear reactor can burn its own nuclear waste to produce energy, relying on a process called nuclear transmutation.

In this process, the waste is converted into progressively lower-energy forms via further similar reactions. This means that almost all of the available energy can be extracted from thorium or uranium, the fuel sources most often used in nuclear energy plants. Scientists believe that this form of energy production is so efficient, it could provide for 100% of the earth’s needs for up to five billion years. Many people fear nuclear power, however, because of accidents like those at the Chernobyl Nuclear Power Plant in the Ukraine and the Fukushima I Nuclear Power Plant in Japan.

A disaster of this magnitude can not only kill workers and others near the power plant, it could potentially lead to an increase in cancer in the population exposed to radioactivity released during the incident. A very small number of incidents of this magnitude have occurred, however, and even the Fukushima Daiichi disaster, which was one of the biggest in history, is not expected to increase cancer-related deaths in the area significantly. Cleaner Fossil Fuels Aside from developing new energy sources, another goal of the green energy movement is to refine existing fossil fuel technology to make it more environmentally-friendly.

An example of this is so-called clean coal technology, which attempts to reduce gas emissions from burning coal. One means by which this can be accomplished is to convert coal into a gas, and then generate energy by burning the gas. While this type of energy production is cleaner than traditional methods of burning fossil fuels, critics believe that the environmental cost is still too high. Another issue is that even though the technology is less harmful, coal is still a finite resource.

Green Technology Essay.

There are many things in this world that are ever evolving in technology, from vehicles, television, cell phones, and even green technology. Some of us might not be too familiar with green; however, most people use green technology without even knowing the difference. The following will address questions concerning green technology. 1. What is green technology? 2. What advantages and disadvantages does green technology have? 3. What are the important focuses of green technology? 4. How can Green technology can be profitable? 5. What are the important facts about green technology? 6.

What is the future of going green?

This is a review of green technology which focuses on these six questions. What is green technology? According to the articleshub. org (2009) the term “technology” refers to the application of knowledge for practical purposes the field of “green technology” encompasses a continuously evolving group of methods and materials, from techniques for generating energy to non-toxic cleaning products. What advantages and disadvantages does green technology have? The advantage of using green energy sources is that it is clean so it does not emit anything harmful into the air which has an impact on the environment.

It is also renewable which means we will never run out of it unlike oil which is expected to dry up in a decade or so. (Elise, M. , 2010) Disadvantage of green energy source is the amount of produce electricity, how much it can generate is not consistent. This is because we have no control of the weather so if a certain area relies on solar energy and there is a weather disturbance, it will not be able to convert sunlight into electricity. Another disadvantage is the fact that some of the green energy sources cannot be installed in certain areas of the planet.

For instance, wave energy can only be utilized if the waves coming from the ocean reach at least 16 feet. The use geothermal energy can only be done in geologically unstable parts of the planet. (Elise, M. , 2010) What are the important focuses of green technology? The most important focus of green technology is changing the production and waste patterns This method is the process of throwing out old methods of production and waste that harm the environment, and creating new ones that produce the same result. Another important part of green technology is innovation. Nvudev. org, 2012) Nvudev. org (2012) stated “there is new innovative and alternative technology that does not harmfully affect the environment or its people.

Another important part of green technology is energy. Energy is another important part of green technology. Energy is a resource that powers the world. Whenever we find new sources of energy and new ways to distribute that energy is important to the future of the human race. Another focus of this technology is ensuring that products produced are re-usable in the future”. Nvudev. rg (2012) believes “Green technology is important because the methods the planet uses now are depleting our o-zone.

Think of green technology as taking the planet earth back a couple of centuries, when a simpler form of survival existed. Technology like this can only be beneficial to the planet. Green technology is the new wave of today’s society. To ensure that planet earth still exist one hundred years from now, education in “going green” is essential. The key to this type of technology and way of life is making it sustainable for everyone over a long period of time.

New methods and ideas will be needed to create a world free of hazardous procedures that humans use too readily to survive”. Elise M. (2010) stated “Green technology is a system that incorporates the new and innovative methods and materials used to create more environmentally friendly cleaning products. The expectation with technology like this is to change the daily habitual habits of society. Green technology focuses on household cleaning products, waste, inventions, clothing, energy sources, etc. Many focus points make technology like this sustainable”. How can Green technology can be profitable?

According to (Schoof, 2012) Green Technology can be profitable. “The United Nation in a large institutional investors meeting at a conference stated climate change is a risk to avoid and also the opportunity to make good return on investments. The investors, who control more than $20 trillion worldwide, are looking at climate change from a business perspective even as Washington steers clear of the issue. Clean energy investments worldwide grew 5 percent in 2011 over 2010, despite financial turmoil in Europe and a wobbly economy in the U. S. , according to a report released”.

Global clean-energy investments reached $260 billion in 2011, about five times more than the $50 billion in 2005, according to a Bloomberg New Energy Finance report. (Schoof, 2012). In the US, only 7% of green energy sources are used nationally. This was much higher 11 years ago. We have to invest more in this clean green energy technology. We can get it from green energy sources such as biomass, biodiesel, geothermal, solar, water and the wind. These are things we have all around us and all it takes is for someone to harness it instead of relying on traditional non-renewable means to produce energy.

Schoof (2012) believes “Globally, solar attracted much more investment than any other source of renewable energy. GE invested $5 billion in research and development in clean energy and efficiency technology. If solar energy is being used and the sun is covered, the emergency generators will be activated and use up the energy that was stored from previously sunny days”. According to the green technology and global market (2012) BCC Research predicts that the global market for energy-efficient technologies will grow at an aggregated compound annual growth rate (CAGR) of 9. % for the 5-year forecast period of 2010-2015, from $200 billion in 2010 to $311. 7 billion by 2015, compared to $331 billion for renewable energy.

What are the important facts about using green? By using green energy, wind, solar, geothermal, hydropower, those sorts of things, those are what we call different types of green energy because they are non I’m going to call them non-invasive because they do not disrupt our environment, they actually help to improve it by not creating CO2 emissions and that’s where were going.

If wind turbines need more space, they can be installed near the coast instead of putting these on land. (Elise M. , 2010) According to Elise, M. (2010) a study shows that you can generate more electricity while these are placed out in the ocean water. In fact, research is ongoing to try and harness other means to generate the power we need. Power is generated by harnessing the different temperatures in the water. It is currently being used on a small scale both in Japan and Hawaii however if may have a lot promise. There are different types of green energy.

Green energy is directly related to green energy resources. One of the green energy resources alternative resource, alternative energy renewable is hydroelectric or hydropower, simply water being used to generate electricity. Solar has been used on a small scale for decades. Today solar is now use on a large scale for homes, industry, and buildings. (Young, 2009) Green technology is a system that incorporates the new and innovative methods and materials used to create more environmentally friendly cleaning products. The expectation with technology like this is to change the daily habitual habits of society.

Green technology focuses on household cleaning products, waste, inventions, clothing, energy sources, etc. Many focus points make technology like this sustainable. (nvudev. org, 2012) In order for green technology to have an impact on the environment for the long term it must be sustainable for everyone every day. Sustainability refers to the use of new technologies in a way that will not harm the planet. Green technology researches new ways to use our natural resources without depleting them, and without making it harder for future generations to survive. (nvudev. rg, 2012)

What is the future of going green? Technology like solar power and the use of new fossil fuels play a huge part in energy efficiency. Perhaps the most innovative section of green technology is green nanotechnology. This technology refers to the use of both green chemistry and green engineering to perfect the whole notion of going green. If solar energy is being used and the sun is covered, the emergency generators will be activated and use up the energy that was stored from previously sunny days. (Elise, 2010) The future concerning green computers have taken technology to the next level.

Green computers are considered environmentally sustainable and eco-friendly. This system of green computers consists of energy efficiency, cost, recycling ability, and environmental sustainability. That’s a lot of energy to use for such a little task. Many companies are working on new and innovative ways to improve computer technology. This is known as green computers. (nvudev. org, 2012) Companies like Dell, Microsoft, Asus, and Gateway are all turning to green computers for the 21 century. The most efficient green computer out of these is the Asus EEE, then the Dell.

The dell green computer is already ready for distribution in large numbers. Green computers are smaller, more energy efficient and recycle ready. (nvudev. org, 2012) In my conclusion I have learn that Green Technology is based on the premise that businesses have a responsibility to satisfy human needs and desires while preserving the integrity of the natural environment. There are significant indications that environmental issues will grow in importance over the coming years. Long-term sustainability of the planet is likely to require some rather distinct changes in the ethical behavior of its human population.

In the short term finding new ways to incorporate technology and carry on exchanges with greater concern for environmental goods and services offer particular promise. Green Technology and the promotion of responsible consumption are part of that solution. There are many things in this world that are ever evolving in technology, from vehicles, television, cell phones, and even green technology. Some of us might not be too familiar with green; however, most people use green technology without even knowing the difference.
