而且，象所有的海洋能一样，潮汐能可能最容易出现在最不需要的地方——远离人口中心的地方，在那里与全国高压输电网连接上是很昂贵的。

And, like all Marine energy, tidal power may be easiest to produce in places where it is least needed-far away from centres of population, where connections to the national grid would be expensive.

设备的水下安装成本和影响海洋环境的担忧耽搁了潮汐能试验，但是这种局面正在改变。

The cost of putting equipment under water and concerns about the impact on the Marine environment have kept tidal experimental, but that's beginning to change.

我开始想，应该能找到一种实用、有效而负责任的办法，来驾驭海洋潮汐的能量。

I began thinking that there's got to be a way to harness all the energy of an ocean swell, in a practical and efficient way, in a responsible way.
