The pioneering plants in the area known as The Geysers highlighted the promise of geothermal energy, internal heat from the Earth with vastly greater energypotential than that of fossil fuels.
It has shown that less 1, 2-unit content corresponds to lower potential barrier of internal rotation and hence to lower energy of rotational isomerization.
进一步的研究表明，低1，2-链节含量对应着较低的分子链内旋转势垒和内旋转异构化能。

We can therefore say that the system has internalpotentialenergy.
