You probably have heard about the global energy crisis and how dramatic the consequences can be. But whenever the topic goes deeper and more detailed, one is often left feeling lost.
To start with, what exactly is green energy? Whenever you hear this term, you need to realize the topic under consideration is of depletion of natural resources, especially fossil fuels. Have you ever asked the difference between green energy and the other forms? How will you classify one into green energy? What exactly is the future of green energy? And perhaps the most important of all, is there any contribution you can make for a better future using green energy?
Let’s begin with the basic definition of green energy. It is simply the energy, which doesn’t harm the environment. That means, when energy is produced, the harmful byproducts and waste material produced impact the environment in the least possible way. Compared to oil, gas or coal, green energy must have minimal damage to environment. The term “green” comes from the fact that carbon emissions are quite low consequently there is less pollution. These energy sources are highly environment friendly
When we talk about the sources of green energy, the first ones, which come to mind, are solar, wind, geothermal and water. Biomass, in the form of waste, biofuels, for example ethanol, biodiesel, nuclear energy are all forms of green energy. Waste incineration can also be used a source of green energy. One thing to note is that not all bio energy sources can be classified as green energy sources. Wood, for instance is a great energy source. Yet we all know that burning wood releases dangerous byproducts which seriously affects the environment.
Here is another aspect of the topic. Green energy is used primarily to save the environment. Hence, it is directly linked to energy conservation too. Recycling and minimizing waste and pollution comes in both energy conservation and green energy. Perhaps the best example for this is the solar energy. Using solar cells, we can effectively save and store energy which not only produces no pollution or waste but it also comes directly from the sun (an unlimited supply of energy).
Nuclear energy however is a great controversy in this field. Although nuclear power plants claim they produce green energy too and that nuclear energy is safe, we know that its waste indeed damages the environment when it is released. The mining of nuclear energy, transportation and the whole production process of it release carbon dioxide and other greenhouse gases, which are quite destructive. On the other hand, those in favor of nuclear energy say that the waste stemming from nuclear energy is not released in the earth’s biosphere when it is being produced. They also are of the opinion that the carbon dioxide levels are relatively lower than other sources of energy.
An example of green energy utilization is the wind turbines. One wind turbine in Reading, England, is able to produce energy for up to 1000 households daily. It is estimated that more than 35 million households in Europe and one million households in America are turning towards green energy.
We must always remember that green energy does not negate the harmful effects to the environment completely. It only minimizes them. Energy utilization will always result in an adverse affect to the environment in some way or other. Production of energy is bound to produce pollution. Green energy however decreases the pollution effects.
We have talked about what green energy is. But we also need to know how to use it in order to improve our environment. And how does green energy help to improve our lives? For starters, it will reduce your bills and save a tremendous amount of money. When more and more people turn towards green energy, it will automatically reduce its price. This is the simple rule of economics. If people collectively decide to switch to green energy it will force the energy companies too to develop more green energy.
The United Arab Emirates (UAE) is also playing an active role in sustainable development. In 2013, the 20th Session of the Commission on Sustainable Development was hosted by UAE. Many issues were discussed like climatic change, food security, energy crisis, natural disasters, diseases and other problems. Also there are several organizations in existence, which are working for sustainable development. An example of such organizations is the Middle East Center for Sustainable Development (MECSD), which is specifically used for effective and efficient use of green. Furthermore it also provides a certificate in LEED which stands for (Leadership in Energy and Environmental Design) which has several projects of green energy and green building.
There have been some criticisms of the uncontrollable state of urbanization and use of natural resources to transform the deserts. The artificial islands have reduced the aquatic life forms. It may also affect the use of hydro energy too.
