TenneT的电塔应会减轻他们的疑虑。
Carrying all the cables in a “stack” between the poles, rather than hanging them separately on outward-facing arms, allows them to be arranged in a way that causes the individual fields generated by each cable to cancel each other, weakening the overall field around the pylons.
电塔之间的电缆都在一块，而不是在向外伸出的杆上分开挂着，每根电缆产生单独磁场，相互干扰，降低了电塔周围的总磁场。
The result is far less low-frequency radiation.
新式电塔大大减少低频辐射。
The combination of being less of an eyesore and producing less electrical smog should, TenneT hopes, soften objections to the construction of new overhead power lines.
TenneT希望不碍眼和低辐射能减少人们对修建新电塔的异议。
That is important for two reasons.
主要因为两点，
One, the alternative—burying high-tension lines—is expensive and largel futile.
首先，掩埋高压线这一替换既贵又不实用。
The cost of putting a cable underground is between four and ten times as much as that of carrying it on a pylon.
把电缆埋在地底的花费是架电塔的四到十倍。
On top of that, the field generated by an alternating current interacts with the ground more strongly than it does with the air.
除此之外，在地下交流电相互影响产生的磁场比在空中强烈很多。
This creates losses 40 times higher in a buried cable than in an aerial one. Unless the long-distance-transmission system were converted to direct current, burial of transmission lines is not a serious option.
地底铺线比高空架线成本高了40倍。除非长距输电系统转换成直流电，地下输电才不至于是个笑话。
The second reason TenneT's pylons may be important is that despite these problems a lot of new long-distance-transmission lines are going to have to be constructed, soon. Wind power from the North Sea and the Atlantic Ocean will require that.
其次，不管这些，TenneT的电塔很重要是因为很快要修建不少新的长距输电线路，北海和大西洋的风力将会需要。
So, more speculatively, will the idea of generating solar power in north Africa and transmitting it to Europe.
所以理论上北非太阳能发的电传输到欧洲的想法越来越有可能。
In the Netherlands alone, TenneT says, more than 400km of new lines are needed.
TenneT表示，单是荷兰就需要400多千米的新电缆。
In Germany, the state-owned energy agency, DENA, reckons that figure is more than 3,500km.
德国国家能源部DENA估计得需3,500多千米。
At the most recent meeting of the European Council, on February 4th, the leaders of the European Union's member states acknowledged that Europe needs a completely new power grid, a project they reckon will cost about 200 billion.
