American should not jump to solar panel roads. Solar energy is definitely an important natural resources, but America should allow France to work on this project and simply watch for now. We should wait to see the pros and cons and asses and improve on the idea from there. We should consider the option, but not for today.
I think that the United States should not make solar panel roads because the technology is too new. While alternate energy sources are worth developing, I think there should be more research put into the viability of solar roads versus the expense of putting them in. I don't think there is enough proof at this point that they work well enough to be worth the investment.
It is not cost effective to use solar panels for making roads. Especially in colder climates in the United States, there is a lot of snow. The roads fall apart quickly in these locations. It doesn't make sense to use solar panels for roads in the United States because the investors will never break even on the costs.
The United States does not need to make roads out of solar panels just because France is doing that. The United States should build roads that based on the most economical way possible. If solar panels prove to be a more economical way to construct roads, then the United States could begin doing that too.
