Building a Hydrological Future

By Dr. Alon Tal. BEER SHEVA (May 22, 2009) — For almost a year now, the Israeli public has been the target of a highly effective public relations campaign by the country's Water Authority. Stark images of desiccated humans cracking like hardened desert soil, along with the more comely admonitions for abbreviated showers from supermodel Bar Refaeli, reinforce existing perceptions that Israel's chronic water scarcity is getting worse.

Nuclear: Carbon-Free but Radioactive

By Benjamin Kahane. Nuclear energy isn’t quite a fossil fuel, since unlike coal, natural gas and petroleum, nuclear is not powered by fuel that developed over millennia from pressurized dead organisms — but nuclear isn’t renewable, either, since it uses a finite non-renewable fuel source. Nuclear power also presents many environmental problems, such as how to handle its radioactive waste product, and, in extreme circumstances, is disastrous, such as in Chernobyl, Ukraine, and recently in Japan.

Solar Power: Let the Sun Shine

By Benjamin Kahane. There are two major types of solar power technologies: photovoltaic and solar thermal. Photovoltaic solar power utilizes the photoelectric effect. A semiconductor material absorbs light and the photons in the light beam are routed through the semiconductor and harnessed in the form of direct-current electricity. The semiconductor cells are electrically tied together in what is commonly called a solar module. These modules can be used to power a direct-current source, such as a battery bank or a water pump, or more commonly the power can be converted into alternating-current power to be used in a home or fed into the electric ...

Energy’s Answer is Blowing in the Wind

By Benjamin Kahane. For hundreds of years, humans have used wind to pump water and grind grain, mostly with small windmills. Large, modern wind turbines are used to generate electricity for individual use and to feed into the electric grid. Wind turbines generally have three blades and, because higher altitudes yield higher wind velocities and lower turbulences, the turbines are mounted on tall towers to capture as much energy as possible. As the blades turn, the central shaft spins a generator to make electricity. Click here to continue reading this article

Green Your Home

By David Krantz. Maybe Kermit was wrong — maybe it actually is easy to be green. Or, at the very least, it is pretty easy to start being green. There are many projects that you can do that will not just green your home, but will keep the green in your pocket, too. Plant a garden There’s no better summer treat than fresh fruits and vegetables grown in your own backyard. And no plot of land is too small for a garden, even if that garden is only a few potted cherry-tomato plants on your windowsill. Plant trees As long as you’re planting, plant big! Trees around a home can help cool a house in the summer and keep a ...

Beyond the Letter of the Law: Jewish Ethical Investing in the Light of Climate Change

Responding to a Dangerous Impasse on Climate Change Climate change resulting from the use of fossil fuels poses a well-documented, grave threat to humanity and the ecosystems that support life. But in the United States, a real national response to climate change has been stymied by political inaction, cultural inertia, and the concerted effort of fossil fuel companies, which have funded propaganda and disinformation in opposition to limits on greenhouse gas emissions. Increasingly, environmental organizations have resorted to various actions meant to break this deadlock. One of these tactics is encouraging divestment from fossil fuel ...

Jewish Energy Guide: Energy’s Answer is Blowing in the Wind

By Benjamin Kahane For hundreds of years, humans have used wind to pump water and grind grain, mostly with small windmills. Large, modern wind turbines are used to generate electricity for individual use and to feed into the electric grid. Wind turbines generally have three blades and, because higher altitudes yield higher wind velocities and lower turbulences, the turbines are mounted on tall towers to capture as much energy as possible. As the blades turn, the central shaft spins a generator to make electricity. In the United States, total wind power constitutes a little more than 1 percent of the total country’s energy output ...

Jewish Energy Guide – Renewable Energy Policy in Israel: Past and Present

By Naomi Lipstein and Dr. Alon Tal The ability to harness energy has been essential to life since the start of humanity. This ability, of course, has come in many different forms and has gone through massive transformations over the centuries. In the 18th and 19th centuries, coal fired the steam engine — arguably the most vital technology of the Industrial Revolution. It was the discovery of oil that allowed the revolution to flourish even further in the late 19th and early 20th centuries, in essence altering civilization. Today, there is little we do without using some form of energy. Energy is necessary for the production of food and ...

Jewish Environmental Response to the State of the Union

New York - The Coalition on the Environment and Jewish Life welcomed President Obama’s affirmation of his commitment to renewable energy and reducing our nation’s contribution to climate change, announced in his State of the Union address on Tuesday. “We praise President Obama for proposing the Energy Security Trust and prioritizing our nation’s response to the threat of global climate change,” said JCPA President and COEJL Co-Chair Rabbi Steve Gutow. “The President has highlighted his understanding of the moral urgency of reducing our contribution to the climate crisis. We hope to see regulations that ...

Pray-in for Climate at White House — Tuesday January 15

Call To Action: A Pray-in For the Climate Dear Friends, We are facing a Climate Cliff, and we are calling upon religious and spiritual leaders, other believers and all people of good will to join us to address its danger by participating in “A Pray-in for the Climate” in front of the White House on Tuesday, January 15, 2013. Super-storm Sandy, the drastic droughts in our corn country, record-breaking Arctic ice melt, and unheard-of floods in Vermont, let alone disasters in Australia, Russia, Pakistan and Africa, all warn us: the disruption of our planet will not wait for our “normal” political paralysis to ...

Working Together Towards Adaptation

A new report just released this week says the ice sheets are melting five times faster than in the 1990’s and occurring more rapidly than scientists believed in 2007 (http://science.time.com/2012/11/30/climate-change-polar-ice-sheets-melting-faster-raising-sea-levels/) . At the same time climate discussion occurring over the last week in Doha have been unfruitful and hope that a meaningful agreement can be reached is fading (http://www.business-standard.com/india/news/doha-talks-after-6-days-no-consensus-yetclimate-issue/494234/). At the same time meaningful discussion is starting to take place in the Northeast regarding whether to ...

The Lawnmower

The Lawnmower by Rabbi Michael M. Cohen written for Vermont Public Radio October 2, 2012 But I can't feel smug about using my battery powered lawnmower, because I know I'm also polluting the earth. It takes roughly 10 cents of electricity to recharge the battery which helps to reduce my carbon footprint, thereby reducing one of the main sources of climate change. But the sources of that electricity are a combination of nuclear, wood, hydro, and wind. And those non gasoline sources of electricity all have their own impact on the environment.

Teach your kids about being “green” at every opportunity!

Cross posted from Environmental Tip of the Week, http://environmentaltip.blogspot.ca/2012/10/teach-your-kids-about-being-green-at.html Teach your kids about being "green" at every opportunity! For example, recently I made a bus out of Legos for my daughter. She loaded it up with little toy people, animals, and food. While she was pushing it around on the floor, I asked her if it was a solar-powered bus. She responded yes. I've explained to her in the past, but said again, why it's better for the environment to power things with energy from the sun. I told her that it doesn't put pollution into the air nor does it contribute to ...

Earth Etude for 26 Elul

Hashem's "Gaslands"* by Judith Feldstein My Lord, You sent us not a burning bush, but Your flaming water; a fire that lives in gas and is not drowned in H2O, with flames that are not quenched, and danger not consumed until we hear and live your will and love Your home as part of You. Last year You gave us Elul with the kiss and aftermath of Your Irene's with all the might of ordained winds and rains and floods. You offered us tsunamis to remember as the earth was shaken, and our towers crashed and crumbled while our people fled or died. Our forests burned, our wildlife trapped in ...

How Energy uses Water

Tonight there is a great Midwestern thunderstorm in the sky. Lightning bolts are flashing, and the rain is pouring down. This has put me in a mood of wonderment at the awesome power of the Heavens, and has 'sparked' my curiosity regarding the relationship between electricity (lightning) and water (rain). While there can be rain without lightning and lightning without rain, the combination of the two is a fairly common occurrence lately, and provides a 'striking' illustration of the connections between these two powerful forces that are so critical to human existence. Unlike in thunderstorms, where water and electricity ...

Israeli Startup Develops Floating Solar Farm

By Yinnon Shraga, NoCamels · While solar energy companies throughout the world are competing for the relatively few vast land areas required to house solar farms, Israeli startup Solaris Synergy has found a new terrain to use. Instead of a land-based solar system, the company decided to develop a water-based technology. In other words: a floating solar power plant. The company’s founders say they realized that the large lands required for thousands of solar panels are nearly impossible to find, especially in a small country like Israel. Solaris Synergy’s Business Development Manager, Dr. Elyakim Kassel, tells NoCamels: ...

Breaking Free from the Fossil-Fuel Pharaoh

The photovoltaic solar-panel array at Kibbutz Ketura is the first and currently only of its kind in Israel. (Photo by David Krantz) KIBBUTZ KETURA, Israel — During the first ever Passover we left Egypt and slavery, celebrating our freedom in the wilderness. It’s easy to forget that back then this stretch of the Arava Valley, a half-hour up the road from the hotels of Eilat, wasn’t part of the biblical Promised Land. No, this part of southern Israel was wilderness — our ancestors wandered through here after the Exodus. It was here, in the desert, where we gained our freedom from slavery to ...
