Yes, all forms of petroleum should be exploited for commercial use, because you never know what might be the next big thing. They used to use kerosene lamps, or lamps that were lighted with whale oil. If petroleum shows potential, by all means, we should use it for commercial energy and whatever else we can.
The United States in the next decade will become a net exporter of oil because electric and hybrid cars will become the norm, plus oil companies will exploit more resources with better technology. The less dependent Americans are on foreign sources of oil, the cheaper gasoline will be. At some point, America's technological prowess will turn the United States into the world's largest exporter of oil rather than the largest consumer. When that happens, Saudi Arabia can kiss our behinds.
I don't think any form of petroleum should be exploited. I do think that all forms should be considered for commercial use. To use the word exploited though takes a bad context. I think we should find the most efficient and cleanest forms and if that is petroleum then so be it.
All forms of petroleum should not be exploited for commercial use. In fact, due to global warming and climate change, the world should seriously curb the use of fossil fuels in the near future in order to prevent catastrophic environmental damage. Drilling itself also causes pollution and can destroy ecosystems.
All forms of petroleum should not be exploited for commercial use. We are already running out of fossil fuels, and they create a ton of pollutants. We need stop exploiting petroleum and start focusing on using renewable forms a energy such as solar power, wind power and hydro electric power.
