We Were There

We were there, in the Negev Desert on Thursday afternoon, June 12th 2008, when Luz 2
inaugurated its first solar energy generating plant.

Two of the JCI team, Michael Kagan and David Miron Wapner had a hand in setting up the company two years ago ago, so it was a proud day for them. For me it was somewhere between science fiction and biblical prophecy.

Luz2 has figured out how to produce solar energy more efficiently and cheaply than anyone else. The technology is dazzling. (Sorry!) In a tract of the Negev near Dimona, 1641 heliostats, 7 metre square mirrors, are geometrically arrayed around a 60 Metre high tower. Perched on the tower is a 15 meter tall boiler, containing densely packed silvered pipes. The mirrors are programmed to track the movements of the blazing desert sun so as to concentrate reflected sunlight precisely on designated spots on the boiler surface. This solar targeted energy heats water in the pipes to temperatures of over 500 C, generating steam that drives turbines that produces electricity. If you want a fuller description than my rudimentary science can provide, see Luz2's site.

Inside the hospitality marquee we ate canapes on square plates and saw videotaped messages from venture capitalists, investment banks and customers who are backing the project. The Pacific Gas and Electicity Company has just signed a deal with Luz for a generating plant in the Mojave desert that will be the biggest solar energy source in the world, roughly 50 times bigger than the baby in the Negev. The company's vision is huge. They aim to build hundreds of these things all around the world over the coming twelve years, producing electricity that can compete with and eventually undercut coal and gas powered plants. This is technology that can produce affordable, efficient solar power, and lots of it. It offers hope that we can switch to renewable sources of energy and avert dangerous climate change in the coming decades.

Arnold Goldman, Luz's visionary founder observed in his speech that the site of the plant is called "Rotem", a type of bush in Hebrew. Goldman remarked that "siach" the general name for a bush means conversation, and that the intense conversations that led to the development of this technology in a certain sense inhered in the physical plant of the mirrors and boiler themselves. In a remarkable book, "Moving Jewish Thought to the Centre of Modern Science", Goldman develops a Kabbalistic theory of language and explains how it underlies the work of Luz. His comments about the Rotem bush were the only hints at such thinking that Goldman gave to this corporate audience.

After the speeches, the public address system played "Here comes the Sun", by the Beatles. I thought of the Biblical verse, ..."to you who fear my Name, the sun of righteousness shall rise with healing on its wings." (Malachi 3:20.)

When I got home I told my technology-mad children where I'd been and what I'd seen. I suspect that one day I will be telling my grandchildren.

Water, waste and wilderness.

It’s water crisis time in Israel again. Spring is here, the turtle dove sings, almond trees blossom, and the winter that’s just passed brought a mere 65% of average rainfall.

This is the fifth consecutive winter to yield below average rainfall in Israel. Some are pointing the finger at global climate change, which is projected to reduce rainfall in Israel by 30% in the coming decades and to cause critical water shortages worldwide. It’s too early to be sure of the connection sure, but the trend is alarming.

As water crises go, this is a bad one. As we look forward to six months of cloudless skies, the Kinneret, Israel’s main water source is 60 cm below where it was this time last year. It's already close to the lowest “red line.” When it falls below that level, pumping any more water from the Kinneret risks seriously polluting it.

Why are we in this situation? After all, Israeli water engineers have been ingenious in maximizing our access to the water sources available. Yesterday I was hiking through Nahal Amud in the Galilee with a group from Hazon and the Heschel Centre, (see next post) and found myself standing in a stone-filled limestone wadi directly on top of the National Water Carrier.

The National Water Carrier is a five feet in diameter concrete pipeline that conveys a third of Israel’s drinkable water from the Kinneret to the centres of the country’s population, and the thirsty Negev beyond. Built in the 50’s and 60’s it was a triumph of Zionist pioneering ingenuity. During its construction, half of Israel’s cement output went into building the pipeline wall. It’s a man made miracle, as awe inspiring in its way as the wadi we were hiking through. Beneath our feet lay the artery which, by pumping precious life-blood to the heart and extremities of Israel has made possible the building of the country.

Today too, Israeli technology enables us to make the most of our limited water resources. Two major desalination plants opened in the past decade and now provide almost a sixth of the country’s water.

But here’s the problem: That’s exactly the amount by which water consumption has grown in Israel over the same period. We now use 796 million cubic meters of water per year, 136 million more than in 2000. As living standards have risen, the gains from new technology have been wiped out by the greater extravagance of our water use.

That’s why technology, though wonderfully helpful, is unlikely to solve this problem alone. We’ll always find ways to consume the blessings that technology yields. To avert future water crises, we’ll have to get into the habit of consuming less.

It can be done. In the face of the water shortage of the early 90’s public campaigns to conserve and reduce water usage cut consumption by 15%.

Everyone knows what to do: take shorter showers, use a bucket and not a hosepipe to wash your car, use the mini-flush lever on your toilet, don’t leave the tap on when you wash the dishes, water the garden at night not at mid day etc etc. All very doable. But when last the crisis passed, water usage bounced back to previous levels and then beyond.

Recently I had the chance to visit the bare and frugal apartment of one of Israel's leading poskim halakhic decisors) and ask him whether there was any halakhic basis for requiring people to save water.

He looked at me as if I'd just asked him which way was up and answered,

"Of course. We should always consume only as much as we need of the blessings that God puts in in the world." (He proved this from Mishnah Berurah, Orach Haim 242:4, which says that people should limit their consumption during the week so that Shabbat will be extra special by comparison.)

Most of us cannot live as simply as this rabbi. But we can share his gratitude for the blessing of water and learn to use it with an appreciation of its preciousness.

Why is this climate change organization different...?

Why a Jewish Climate Initiative? Surely climate change is a global problem? Isn’t everyone today concerned about it?

We spent quite a few late nights and Espressos debating these questions ourselves.

Our answer is that yes, many people are, and we applaud and support their efforts.

But the scale and urgency of the problem requires everyone to play their part. We have barely begun to imagine, let alone make, the immense shifts in individual behavior, government policy and ethical consciousness that will be necessary if we are to avoid dangerous climate change.

We believe that the Jewish people has a large, unique and until now, untapped contribution to make, through its combination of ethical wisdom, scientific and business know-how and activist passion.

Jewish Climate Initiative aims to be a catalyst to mobilize these strengths for the good of our children and of the planet.

Part of what makes our response distinctive lies in recognizing the holistic nature of the climate change crisis. The challenge of global warming requires a marriage of moral and spiritual vision with scientific and entrepreneurial innovation. Neither well-meaning ethical exhortations nor purely technical solutions will be sufficient by themselves.


One of the many things we believe faith-inspired approaches to climate change can offer is hope. Hope is a scarce resource in the current climate change discourse. Al Gore observes in “An Inconvenient Truth” that many have passed straight from denial that climate change is a problem to despair that we can do anything about it, without passing through an intermediate stage of hope.

Rabbi Jonathan Sacks argues that hope is a distinctively (though not exclusively) religious virtue. It is not the same as optimism. Optimism is the belief that things will get better. Hope is the belief that together we can make them better.

We hope that you’ll send us your thoughts, responses and suggestions so that together we can help make things better for our children and grandchildren.
