The pros and cons of electric vehicle

Essay

◆ Pros
 Although there are certain disadvantages of electric vehicles, I believe that the advantages overweigh the disadvantages and now I would like to mention about the primary merits of electric vehicles.
 The first primary merit is that electric vehicles do not use gasoline. Considering that one of the most oil-consuming things is conventional cars and oil resources are non-renewable and limited so that it is extremely important not to waste them, this is a real benefit.
 The second primary merit is that electric vehicles do not release CO2. As the world has been more and more industrialized, the environmental pollution has been aggravated. This is one of the most serious problems in the world today and one of the biggest factors of global warming is excessive amount of CO2 release and conventional cars are heavily responsible for it.
 The third primary merit is that if electric vehicles become ubiquitous people will be more interested in environment and be more careful not to damage it. There are over 7 billion people in the world and if every one of them become more careful not to pollute the environment, the effect can be tremendous.
 As I mentioned, the aforementioned things are the primary merits of electric vehicles.

◆ Cons
 Although there are certain advantages of electric vehicles, there are also disadvantages and now I would like to mention about the primary demerits of electric vehicles.
 The first primary demerit is that electric vehicles are so quiet that they can be dangerous because pedestrians cannot realize that there is a car near them. Considering that car accident is one of the major causes of death in many countries, this is a serious problem.
 The second demerit is that electric vehicles are still unpractical in many ways. They can run a much shorter distance than conventional cars. It costs a lot of money to build their battery charge equipment. It takes a lot of time to charge their battery. Considering these things, I must say that there are still a lot of problems about electric vehicles.
 The third primary demerit is that it costs a lot of money to produce electric vehicles. Car makers are not sure that they sell well and therefore cannot take the risk of mass-producing them especially in this one of the worst economic recessions in history.
 As I mentioned, the aforementioned things are the primary demerits of electric vehicles.

メモ

◆ トピック:電気自動車の賛否

例によって、賛成派と反対派を書きました。

賛成派では、
「電気自動車は、ガソリンを使わない」
「電気自動車は、CO2を出さない」
「電気自動車が、普及すれば、人々がもっと環境に興味を持つようになる」
の3つを、キーアイディアに書いてみました。

反論としては、
「水素燃料電池自動車の場合、化石燃料から水素を生産するとガソリン自動車以上に環境負荷が大きいのではないか?」
「アルコール燃料電池自動車の場合、アルコールを生成する過程で、CO2が出るのではないか?」
「本格的に普及するのは、一体いつになるのか?その頃に初めて、環境に興味を持っても遅いのではないか?」
などが考えられます。

反対派では、
「電気自動車は、静かすぎて歩行者に気付かれない場合があり危険」
「電気自動車は、まだ、非実用的な面が多々ある」
「電気自動車の生産には、お金がかかる」
の3つを、キーアイディアに書いてみました。

反論としては、
「音の出る装置を付ければいいのでは?」
「少し不便でも、環境を優先するべきではないか?」
「環境のためにお金をかけるべきではないか?」
などが考えられますね。

すこし前に、坂本龍一さんの、日産の電気自動車のCMを、Youtubeで見て、このトピックを思いつきました。
極端な話、地球が消えたら、すべて「THE END」ですので、地球上の全ての存在にとって、環境問題は、もっとも重要な事の一つだと思います。
ですので、「環境問題は最も重要な事なので、お金がかかっても、少し不便でも、取り組むべきだ」という意見も、キーアイディアとして使えると思います。
