The tide energy, like familiar water energy, is a kind of renewable energy.

潮汐能和常规水能一样，是一种取之不尽、用之不竭的可再生性能源。

The semi-diurnal and diurnal internal tide energy densities are large on the continental shelf and in the thermocline of the deep sea.

较强内潮在陆坡区超临界地形上生成，并沿波射线方向传播，导致半日潮和全日潮的能量密度在陆坡区温跃层上较强。

Since it is sustained by the wind and tide energy input to the oceans, diapycnal mixing coefficient (DMC) will vary along with the change of external energy input.

海洋中的混合过程是由风和潮汐输入的机械能维持的，这些机械能的变化会导致海洋中混合率的变化。

This last point appears heretical considering the tide of popular media and policy nostrums about energy tech.

But if the peak were to come after 2020 or 2030, as the International Energy Agency and other mainstream forecasters predict, then the rising tide of alternative fuels will help transform it into a plateau and ease the transition to life after oil.

We are also exploring new sources like tidal energy, which places propellers in San Francisco Bay that move with the tide, and livestock, where you capture cow manure for biogas.
