The pioneering plants in the area known as The Geysers highlighted the promise of geothermal energy, internal heat from the Earth with vastly greater energy potential than that of fossil fuels.

当地开发地热能的先锋——间歇泉电站（TheGeysers）高调宣传地热能源的潜力，这些来自地球深处的热量携带的能量远远超过化石燃料。

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 internal potential energy.

因此，我们可以说，该系统有内势能。
