（２）把路燈和所有的交通信號燈換成太陽能LED燈組

????LED和太陽能燈都非常便宜，一個太陽能LED路燈不到三年就能收回成本。這些燈組應配有電池，因此即便在任何颶風中也能堅持幾天。LED燈的使用時間幾乎是當前路燈的５倍，也就是說維修、養護上可以省下大量的資金。洛杉磯已經安裝了太陽能LED路燈，墨西哥城也打算這樣做。

????交通信號燈也應換成太陽能的，并且配備備用電池。較暗的交通信號燈不僅容易導致危險的駕駛環境，而且也需要大量警力在路口維持秩序。這個領域的領先公司包括Cree、飛利浦（Philips）以及西門子（Siemens）旗下的歐司朗（OSRAM Sylvania）等。

（３）為紐約地鐵系統配備冗余水泵和備用電源

????我們都看到地鐵在颶風中停運后發生了什么。紐約地鐵每天可運送500萬名有通勤需要的人。一旦這500萬人無法出行，整個紐約市的經濟都會蒙受巨大損失。紐約交通運輸管理局（MTA）也嚴重依賴老掉牙的電網，因為地鐵沒有電就無法開行。

????“桑迪”遠去后，盡管紐約交通運輸管理局已經把地鐵隧道里的水都泵了出來，但地鐵還是無法在城區通行，因為ConEd電力公司尚未恢復這一區域的電力。要求紐約地鐵必須配備分布式發電和存儲設備，對于一個目前還經常晚點的地鐵來說，這個要求可能太高了，但打造一個抗風險性更強的地鐵網絡，總歸是一項值得的投資。

????紐約交通運輸管理局目前只有三輛水泵軌道車，首先，紐約交通運輸管理局應在這方面進行加強，同時還要增加應急電力設備。紐約交通運輸管理局從2010年的暴雪中吸取了一些教訓，認識到了讓汽車開到安全區域的重要性，因此至少在這些方面有所進步。“桑迪”颶風后，長島電力公司（Long Island Power Authority）的董事會把它的CEO炒了魷魚，理由是他沒有做好應對災難的準備。由于他的失職，即使周邊地區的電路恢復了很久之后，長島地區仍有成千上萬的用戶處于斷電狀態。ConEd公司的故事則有些不一樣。

????不要等到下一次災害來襲，再次摧毀我們的電力和交通，付出生命的代價和難以估量的經濟損失時才肯幡然悔悟。美國的實際利率已經是負數了，因此在當前的經濟環境下，做出有實際收益的長期基建投資是一個非常吸引人的機會。現在就是投資基礎建設的好時候，而且在這個過程中，還可以增加人們急需的就業崗位和價值。我們等不起了。

2.Convert streetlamps and all traffic lights to solar-powered LED units

????LEDs and solar are both so cheap now that a solar-powered LED street lamp can pay for itself in less than three years with no subsidies. These units have batteries on board so that they can power themselves for days through any storm. LEDs last five times as long as current streetlamp technology which translates to big savings in maintenance. Los Angeles has already installed solar-powered LED streetlights and Mexico City has decided to do the same

????Traffic signals should also be converted to solar-power with onsite battery backup. Dark traffic signals not only create dangerous driving conditions, they also require enormous police manpower to maintain order at intersections. Companies to look at in this space include?Cree(CREE), Philips (PHG) and OSRAM Sylvania unit of Siemens (SI).

3. Invest in redundant pumps and power for the NYC subway system

????We see what happens when the subway goes down -- loss of productivity across the NYC economy as its daily 5 million commuters are stranded. The MTA is dependent on our outdated grid as electricity is needed to operate the third rail.

????Even after the MTA had pumped out all of the water in the tunnels using diesel trains, following Hurricane Sandy, subways could not operate downtown because ConEd had still not restored power in those areas. To call for distributed generation and storage for the subway?may be a tall order for a system that still has delays on a regular basis, but it is a worthwhile investment to build a more resilient subway network.

????The MTA only has three pump railcars and should augment this with additional pumping and emergency power equipment. The MTA did learn from the 2010 blizzard the importance of moving cars to safe areas so at least those procedures have improved.

????After Sandy, the board of Long Island Power Authority fired its CEO with good reason -- he did not prepare for the storm and his negligence left thousands of customers offline well after other areas were back online.?The story at ConEd will be different.

????Let us not wait until we are hit with the next disaster that takes out our power and transport systems and costs lives and untold financial impact. Our negative real interest rates make long-term infrastructure investments with real returns an attractive opportunity in the current economic environment. Now is the time to invest in our infrastructure and to create needed jobs and value in the process. We cannot afford to wait any longer.
