Summary: The ocean, according to Pulitzer Prize finalist Dr. Christopher Vaughan, is a relatively untapped resource, but advances are now being made in creating wave and tidal energy systems.
The complex relationship between energy and water promises to be one of the most significant factors in global development going forward. Freshwater supplies are endangered in general, but the equation varies greatly by region and state of development. Most uses of water in energy production result in electricity generation, typically using hydraulic turbines in dammed rivers. Energy derived from water sources varies from an almost complete reliance on hydroelectric power in many nations to relatively scanty percentages in the United States (about 6.6 percent) and Israel (less than 1 percent). Worldwide, hydroelectric sources comprise 20 percent of energy supplies.

The Jewish Energy Guide presents a comprehensive Jewish approach to the challenges of energy security and climate change and offers a blueprint for the Jewish community to achieve a 14% reduction in greenhouse gas emissions by September of 2014, which is the next Shmittah, or sabbatical, year in the Jewish calendar.
The Jewish Energy Guide is part of COEJL’s Jewish Energy Network, a collaborative effort with Jewcology’s Year of Action to engage Jews in energy action and advocacy. The guide was created in partnership with the Green Zionist Alliance.
