Although it’s a new technology, solar energy provides benefits to the entire world. First, solar energy eliminates our reliance on non-renewable fossil fuels. Additionally, solar energy is non-pollutant, which makes it better for everyone. Finally, there is almost no maintenance as solar panels have a long life span without regular maintenance. So, the benefits seem to be overwhelmingly positive and supportive of further production. The first benefit is the ability for solar energy to reduce reliance on fossil fuels. Many sources of energy are renewable only over millions of years. Unfortunately, humans consume those faster than they are produced. Solar energy could be a replacement for non-renewable sources as a perpetual source of energy. Thus solar energy can become new energy with no legitimate fear of overproduction. Another benefit is the non-pollutant aspect of solar energy. Burning fossil fuels is known to produce deadly pollution, while solar energy produces zero harmful byproducts. While current energy sources produce disgusting smells, sounds, and visuals, solar energy produces nothing offensive. Therefore, when considering the health of the planet, the lifelong health benefits of solar energy are unparalleled. Finally, solar energy has low costs. The cost of solar panels is a one-time purchase. Also, after installation, the lifespan of a solar panel is thirty years. After the initial cost, the solar panel will cost almost nothing. This is a benefit to personal finances, but also peace of mind since there is no worry about rising prices or lack of resources. In conclusion, these benefits provide support for more people to consider switching to solar power. Both the renewable aspect as well as the non-polluting aspect means that there will be added benefits for individuals, cities, and the planet. The low lifelong cost of installation and maintenance provides a lifetime of benefits. Thus, solar energy looks to be one of the world’s great ideas.
Recently, there has been a ton of debate as to the advantages and disadvantages of using solar energy. More specifically, in regard to the passage, the writer puts forth the idea that using solar energy has a lot of benefits. However, in the listening passage, the lecturer is quick to point out that there are some serious flaws in the writer's claims. In fact, the professor believes that there are huge disadvantages in the case of using solar energy and addresses, in detail, the problem of each point made in the reading passage.
First and foremost, the writer of the passage states that the cost of solar energy is very low because the cost of the solar panel is a one-time purchase. Moreover, after the initial cost, there is no other large cost. Some professionals in the same field, however, stand in firm opposition to this claim. In the listening, for example, the professor states the production cost of the solar panels is very high. He goes on to say that as the high production cost of solar panel, it is better to use renewable energy sources.
Secondly, One group of scholars, represented by the writer, thinks that solar energy used is very profitable as is using is much reliable. Of course, though, not all experts in this field believe this is accurate. Again, the speaker specifically addresses this point when he states the control of solar energy use is very tough. He notes that there are a lot of possibilities to waste solar energy.
Finally, the author wraps his argument by positing that solar energy production is very easy. Not surprisingly, the lecturer takes issue with this claim by contending that much energy need to produce solar energy.
