Solar-Powered Water Heaters in Israel

On its face, the initiative may not appear to be all that important, but the Israeli people have taken advantage of their geographic location to significantly decrease their dependence on foreign imported energy and increase their self-sufficiency by installing solar-powered water heaters on residential rooftops across the country. For instance, according to Sandler, "Rooftops all over Israel look strikingly similar: More than 1 million households in the nation of 7.1 million people have solar panels that produce hot water -- a relatively simple technology that gained popularity after the 1973 Arab-Israeli war, when oil prices shot up sharply" (2). The ubiquity of these rooftop solar-powered water heaters is readily discernible in Figure 1 below.

The impetus for this initiative gained momentum in the early 1990s when the Israeli government mandated that all new residential buildings must install solar water-heating systems (Sandler), and for good reason. According to Hamer, "Solar energy is especially well suited for heating water, a task that requires 15 -- 20% of a home's total energy consumption. Solar water heaters can provide 50 -- 90% of that hot water, and their original cost can be recovered through energy bill savings over the course of 4 -- 7 years" (145). From a strictly pragmatic perspective, this initiative is also making a significant difference in the energy-dependency of Israel. In this regard, Hamer adds that, "The potential value of the technology is shown in Israel, where solar hot water heaters displace 6% of the country's total electricity consumption" (146). By using improved solar power technologies, that percentage could increase to as much as 16% a major factor for Israelis given that the nation is almost entirely dependent on imported energy sources (Sandler). Beyond the energy savings realized by solar-powered hot water tanks, there are some other benefits to using Solar energy in Israel. For instance, Abramowitz and Lehreer emphasize that, "Israel's heavy reliance on imported, carbon-based fuels is bad for the environment and for public health. Fortunately, Israel is blessed with enough sunshine: Solar power alone could fuel up to 40% (8 gigawatts) of Israel's anticipated electricity needs by 2020" (2). This point is also made by Katsioloudis, Bondi and Deal who emphasize, "In countries like Israel, the abundance of solar radiation, together with a good technological base, has created favorable conditions for the exploitation of solar energy" (11).

Despite their ubiquity, the solar-powered water heaters… [END OF PREVIEW]
