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 a 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.
The lecturer supports compliments some advantages of solar energy that has been stated in the essay with more details. The argument in the essay that states that solar energy is a clean form of energy is emphasized by the speaker in the audio. He mentions that the energy used to produce the solar cell is balanced out with the energy it produces within the first five years of its use.
The lecturer only seems to point out the advantages of solar energy and does not mention the disadvantages of other forms of energy such as its non-renewability and the production of harmful by products as mentioned in the essay. The low cost of maintainence is also well supplemented by the lecturer when he says that even some people produce excess power that they sell. This is because of the privatisation feature the solar panels give so that the people control the amount of energy it produces. According to the lecturer, added financial advantages such as tax benefits may also prevail when one decides to start using solar panels as their primary source of household energy.
