With a rapid rise in energy prices, the concern of pollution, an exponential loss of resources and environment downfall, the awareness of limited resources around the world has dropped dramatically. Due to recent political decisions by President Donald Trump, with his recent 30% tariff on solar panels, affording solar technology will be more difficult than ever (Eckhouse). These tariffs will go on for four years by starting at a high percentage, then finally go down as time goes on. Utilizing renewable energy is the key to a long-term solution for keeping this economy alive and well. Recent research shows that bringing solar technology overseas into the United States is an extremely expensive change, but is cost-efficient in the long term. …show more content…
When I lived in Arizona about seven years ago, I attended a school named Cottonwood Middle School. This school implemented solar technology over a parking lot by putting a structure that is above the cars to provide shade and also a place to hold solar panels. This saved a lot of money for the school and the school district due to utilizing solar technology to the fullest. This started when I was in six grade I only my middle school, but then a progressed and to all of the schools in the district. This included a kindergarten through third-grade school, an elementary school and also a high school in Cottonwood, Arizona (Tracey). This was the first time I have ever seen a solar panel in use, and I know it was used effectively to benefit money by utilizing renewable resources to the max. Solar energy is described as radiant energy that comes from the sun and it is called solar technology, which uses it as energy to power almost anything. Solar technology is an important factor of renewable energy and it could be …show more content…
There are many different types of green technology and the most common ones are solar, wind, and hydro-power. There are many reasons why this renewable source of energy is better than these other sources. Wind energy is produced by turbines that have rotating blades they can harness the kinetic energy. These turbines have generators that whole onto the kinetic energy from the movement of the blades and currently has enough electricity through these turbines to power about 24 million homes. There is a problem with turbines and for a typical turbine for residential use would have to be about twenty stories tall. There are three separate blades that are about two-hundred feet long from one end to the other that span out from the inside portion of the turbine. The average wind speed needs to be about twelve miles per hour in these zones to produce enough energy to harness for a typical resident (Aggarwal). If you live in an area with a lot of wind and open space with a few obstructions that could block the path of the wind, then installing wind turbines would be a great renewable energy source. But, many people that love the environment with enough money to install turbines live in suburban areas around a city. Compared to solar panels, wind turbines have a lot of moving parts that can result in more wear and tear and there will be a lot of maintenance visits to these turbines. Solar panels
The future of the United States solar energy industry will be shaped not only by economic growth, but also by the rate of declining oil resources and the global realization of the consequences of human induced climate change. Political responses to this realization in the United States include; new policies, legislature, and tax incentives to both businesses and private households to promote growth and investment in the solar power industry.
Although solar seems to be excluded from most of the disadvantages listed above tied to using renewable energy sources, it still has two big main disadvantages. The first being that, it is impossible to shut off. The fact that there is no way to shut these solar panels off makes them prone to catch fire. This is harmful to the place they are located. It is especially bad when people put them on their roofs which can cause house fires. Another big issue with solar is that it takes a lot of room for the amount of energy that it produces. According to the U.S. Energy Information Association to produce 1 MW of solar energy, assuming that your panels are located in price sunny locations, it takes 7.4 acres of solar panels. When you compare it to the nuclear reactors that produce on average 770MW for approximately 500 acres of land. To produce the same amount of energy as one single nuclear reactor you would need approximately 5698 acres of land which is 11 times the amount of space that nuclear
Most of the people in our modern day society are beginning to realize that fossil fuels are becoming more rare and are damage our planet, this creates the need for a more sustainable form of energy. Solar energy is one of them and is becoming more and more important and will hopefully soon replace this obsolete technology.
One reason why solar energy helps is because it reduces electricity costs. Electric bills could be catastrophic for some families and many people may be struggling to pay with other types of bills too. That’s where solar energy comes in and is a great substitute for electrical energy. Adding solar panels to your home can bring in monthly savings of above $100 in many states such as Hawaii which residents there save on average $64,000 after an estimated 20 years! You save more money and waste less energy which is what we really need nowadays in life. Going solar can help save you tons of money you never imagined to have before
...company by subsidies and reduce the cost by incentives on tariff and policy for boost the development of solar energy. Secondly, the low efficiency may improve by the innovation of technology which are the technical and design improvement on photovoltaic systems, storage systems and concentrated solar power systems. The above findings demonstrate the need to mitigate problems with using solar power not only because it is an alternative energy but also because solar power has huge long-term benefits as an endless, sustainable and clean future energy. Therefore, this report recommends that government need more promotion in future to support and boost the research and development of solar energy system which also need the collaboration of the scientist on technical issues. A further recommendation is public encourage in order to widely utilize solar energy in the world.
Solar is a viable alternative energy source with solar panels becoming more affordable and more efficiently designed.
The use of solar power is all around us. Calculators, roadside emergency telephones, and street-side speed radars all utilize the sun’s limitless rays to provide power for their simple functions. As simple as these functions may be, solar power is nonetheless capable of powering much greater things. The technology and motivation for this exists; all the planet needs is time and funding before it becomes a planet powered solely by the luminous rays of the great sun. But before this universal shift towards solar power happens, citizens have the choice and ability to install their own personal solar power system for their private homes. After weighing the advantages against the disadvantages, the correct choice should be clear.
Solar power is one of the renewable energy resources that was develops to replace the fossil fuel. It was one of the most convenient and clean energy resources that are available in the earth. The solar power operations involve the conversion of sun power to electric power with the use of photovoltaic cell. The whole process is clean and will not produce pollutant to environment. In 2011, the International Energy Agency encourages all countries to develop solar power technologies. They emphasis that the early development investment cost should not be cut down and the research should be shared among the countries as solar power technologies brings huge global long terms benefits toward mankind. Such an advantages include: increase the countries energy security as solar power is a free and inexhaustible resources that can be obtain from the sun, reduce the pollutant toward the environments, and decrease the energy dependent toward fossil fuels which will lower the price of fossil fuel. These energy resources are the mos...
As the increase in the consumption of energy gradually increases per year, the government needs to take measures in opting to renewable energy sources, preferably solar energy because of its decreasing price, versatility, and its abundant main source of energy.
An advantage of Solar Energy is that it is easy to obtain. So here in El Paso it would be easy if the whole city would be powered by Solar Panels. Solar Energy is also very efficient. The panels could be charged during the day and when there is no sun, the energy from the previous day is already stored. “You can use home solar panels as a partial or full source of electrical energy for your home. These residential solar panels can be tied into the electric grid, or you can produce all energy you need and live "off the grid". Solar systems that are tied into the grid can even sell unused electricity back to a power company”. As said by a (worker of the Solar Panel company in solarenergy.com)
The Earth captures around 342 W/m2 of energy from the sun. This energy is in the form of solar radiation, which the atmosphere reflects about 77 W/m2 and will absorb around 68 W/m2 of solar radiation annually. Therefore, the Earth’s surface is receiving, on average, about 197 W/m2 of solar radiation annually. This amount of energy received is roughly more than 10,000 times the amount of all energy humans consume per year. This energy can be used to produce electricity or heat. This energy source is not being used to it’s potential considering how much effort would come into effect to store and transport this energy.
One of the best ways of creating green energy is through wind turbines.Wind turbines generate electricty through kinetic energy from the wind. When wind blows and catches on the blades they spin, which then makes a generater convert that into usable energy. Some places are making wind farms or, gaint arrays of wind trubines. These wind farms can make a small contributon to domestic power so we are using less unclean energy. Windmills are an endless source of energy that does not harm the environment.
Solar energy is that energy which is gets by the radiation of the sun. Solar energy is present on the earth continuously and in abundant manner. Solar energy is freely available. It doesn’t produce any gases that mean it is pollution free. It is affordable in cost. It has low maintenance cost. Only problem with solar system it cannot produce energy in bad weather condition. But it has greater efficiency than other energy sources. It only need initial investment. It has long life span and has lower emission. The sun is the original source of almost all the energy used on earth. The earth receives a stock ring amount of energy from the sun, as much energy falls
Solar power is only one of the forms of energy. Solar power has its advantages but most of the people the people think the solar panels are expensive disadvantages, but it’s actually an advantage. Solar power starts saving money from day one. Electricity is one of the key things we need to clean up and solar power is the way to do so. (Shanan 1-4) Solar energy is a visible form of alternative energy. Solar panels capture energy from the sun’s rays and convert it to electricity. Solar power offers a clean form of energy. Solar energy carries political considerations just as petroleum does. (Linden 1-4) Virginia Water Resource Research Center has found that solar photovoltaic uses about 21 times less water than nuclear power about 16 times less water than coal power and 8 times less water than a combined cycle power plant. (Shanan 1-4) Solar power has disadvantages also. Solar panels make a ton of pollution when their built, and sun doesn't always shine on them. (Shanan 1-4) They may take several years too see a return on investments. Solar energy is not universal because different areas of the world get different amounts of sunlight. Solar energy may not offer the best solution: there distractions, they have high environmental costs and they have a large outlay of cash. There can be contamination from radio activation saved used to make solar panels. (Hinder 1-4) Installation is expensive being $80,000 for a three bedroom after the federal rebate. The angle of the roof, percentage of sunlight and the area of the country all play a part in the effect of how much it will co...
Wind is a form of solar energy. The term wind energy describes the process by which the wind is used to generate electricity or mechanical power. Wind turbines convert mechanical energy from the wind into electrical power. Wind turbines usually have three main parts. There are blades that connect to a central hub, a box behind the blades that contains the generator, and a long stem that connects to the ground. The way how it works is that the wind turns the blades, which spins a shaft that connects to a generator making electricity. After the electricity is produced it is sent through transmission lines to a substation that is sent to business and homes. For the sake of our planet, we must promote a renewable energy economy. Wind power can be a foundation of that sustainable energy future because it provides jobs in states that are building wind turbines, is a renewable energy source, and does not damage our environment. The environment will not be damaged by the pollution, the natural resources will not be used up, and there won’t be generating of hazardous wastes. Welcoming wind energy today will lay the foundation for a healthy tomorrow that will affect everyone in the United States. There are obstacles and challenges that will make it more difficult, but the environmental impact is well worth it to invest more money into wind energy.
