ADVANTAGES AND DISADVANTAGES OF RENEWABLE ENERGY WRITTEN BY: ALMAZ HAMID Renewable energy is a type of energy where all its resources comes from water, sunlight and waste materials. Renewable energy is environmentally friendly because non-renewable resources for example, oil is not involved. This will eliminate the emission of sulfur dioxide into the air when the oil is burned and this will reduce global warming. The two types of renewable energy that I will be mentioning in this essay are, Hydroelectric power and Solar power. Hydroelectric power is a type of energy where it relies heavily on water to produce electricity. Solar power is a type of renewable energy where it relies heavily on UV rays for it to function. Scotland is noted for using hydroelectric power. In order for hydroelectric power to function, dams must be built in lakes and have sluice gates installed. The sluice gates can be closed in order to trap water inside the damns. This method is used to save water and the water will be used during the pro...
Reservoir storage is crucial in maintaining available water for use throughout the summer by storing the snowmelt each year, which accounts for 70 percent of Wyoming’s entire water supply and allows for 1.9 million acre-feet of new water flowing into the state each year. All of thes...
The sun has been a major aspect of life since the beginning of time. People used many other forms of energy before electricity was discovered. There has been a debate over energy resources for years. Many people are worried about what current energy resources may be doing to the environment. Oil spills and nuclear power plant mishaps have only been a few accidents that have had a big impact on the environment and the people who inhabit it. There are plenty of energy sources that do not harm the environment and are still able to get the job done. Solar energy is one energy alternative that will insure the betterment of the country and, at the same time, protect the natural environment.
However, it is important to be able to both protect water and sources to ensure water supply. In this day and age, there is
Another use of hydropower is pumped storage. In pumped storage plants, water is pumped from low resevoirs to a higher reservoir during off peak times, using electricity from different types of generators. Operators release it back into the lower reservoir through turbines if power is needed. Some power is initially lost, but pumped storage systems can be about 80 percent efficient. Sometimes it's important to meet power demands where hydro plants have an advantage in their abilities when they also have reservoirs. Most plants may only produce hydro power all the time and can't be adjusted when it comes to wanting more power in times of need. Whereas hydro plants with dams save up the water and allow it to flow only during peak times. These peak times can be beneficial to whitewater enthusiasts, but can also inhibit fishing opportunities because of the increased water flow.
In 2004, plan was developed to increase the water supply through dams instead of water recycling. In 2006, focused were on the recycling water
We strongly encourage the Government to invest substantially in research and development on low environmental impact renewable energy such as tidal streams technologies such as tidal fence, offshore wind energy, and wave energy. Doing so, the Government encourages the engineering community to develop designs which are more environmental benign. iii. Due to incomplete knowledge regarding the different technologies environmental impacts and the potential irreparable damages to biodiversity, we believe that a step-by step approach is more prudent regarding the clean energy production infrastructure
The first type of renewable energy is hydroelectric energy or well known as hydropower. In greek word, hydro means water and thus hydroelectric energy refers to electricity generated using flowing water at high velocity. Lutgens and Tarbuck (1992, p. 163) stated that “running water is of great importance to people as we depend upon rivers for energy, travel and irrigation”. Continuous availability of water in universe made water to be the main source of hydroelectric energy. Water has been widely utilized by mankind since the beginning of civilization and wate...
Alternative energy sources are renewable, and is most commonly referred to as free energy sources. There are many alternative energy sources such as hydro power, solar power, wind, biomass, and geothermal. Using alternative sources is more expensive in the long run, but it is the much safer option for our environment compared to fossil fuels. Although everything used is completely free, such as water and wind, the equipment used to generate these things are expensive. There are several pros and cons that come with the utilization of alternative energy sources.
The water that is withdrawn from the source never returns in its original state. In addition, in most cases, only a small volume of it returns to the source. This is a major challenge in areas where the source not only serves the power plant, but also numerous people and animals, as the water gets depleted faster (Rogriguez, Delgado, Delaquil, and Sohns 13). The situation gets even worse when the water is consumed by the plant without returning to its source. Such a situation leads to a significant reduction in the water levels of ...
The examples of using renewable energy are The Solar Panel which is an assembly of solar cells. The solar cells convert solar energy into electrical energy. The solar panels are very expensive even though they cost nothing to run. They are installed in places which must have sunlight. The efficiency is 10-20% the environmental impact is it needs very large areas, 40km² is needed to produce to produce the equivalent power of one modern power station. Does not cause pollution but there are environmental concerns about the production of storing devices.
Energy can be defined as the power we use for transformation, for heat, for light in our home and for the manufacture of several kinds of products. Knowing all the usage of the energy; we can image that life will nearly be impossible if they were no source of energy at all. Those sources of energy are classified into two main groups; the renewable energy and the nonrenewable energy. Which one is the most used todays? Is renewable energy going to replace nonrenewable energy in the future? what will be the investor, benefit and cost to our country on our economy?
There are different kinds of resources that we can use in order to produce renewable energy. Solar power, wind power, hydroelectric power are just some of the kinds of renewable energy that might be the best options to obtain energy because they come from natural resources. Although renewable energy can be expensive to build, it has less environmental damage in comparison to non-renewable energy. Besides the natural resources such as sun, wind, water and hydrogen, we also have geothermal power, and biofuels as renewable sources.
In chapter thirteen of our book, Environment by Raven and Berg, it shows us just how important renewable energy sources are. Currently the United States of America thrives on the use of fossil fuels and nuclear power. The main problems with these types of fuel are that they are both limited and can be extremely harmful to our environment. They cause global warming, air pollution, acid rain, and oil spills (Environment), and not only that, but in the grand scheme of things, these sources really aren’t even that cheap of a fuel source. There are many alternatives to these all but outdated fuel sources.
Global warming is an extremely important and troubling aspect of the world’s current situation. This is due to the fact that the majority of the world’s energy production is from non-renewable energy sources, which are energy sources that either can not be naturally replenished or require thousands of years to be restored. Based on our current energy usage growth rates, there are an estimated 100 years left before our natural resource reserves are exhausted. (Non Renewable Natural Resources: How Much Is Left, Environmental Thinker) China alone consumes nearly as much coal as the combined usage of coal from the rest of the world. (US Energy Information Administration, China Consumes Nearly as Much Coal as the Rest of the World Combined) There is visible evidence of this happening with the increasing pollution levels. Carbon Dioxide and Methane pollution levels in the world reached a record high in 2012 and are 260% higher than the pre-industrial levels. (UN: CO2 Pollution Levels at a Record High, John Heilprin) Converting our world into a more renewable energy dependent society is the most advantageous and likely method for preserving our dwindling fossil fuel supply while also protecting the world that we call home.
According to Franchi (2005:72) “renewable energy is energy obtained from sources at a rate that is less than or equal to the rate at which the source is...
