Body:

 One of the most significant sustainability challenges of our time is how we produce, use, and relate to energy.  Prior to the industrial revolution, the most important sources of energy for human uses were animals, people, wood, wind, and water. This changed with the invention of the steam turbine, internal combustion engine, and jet engine, and the use of fossil fuels like coal, oil and gas and of nuclear power. While these technologies greatly increased material standards of living among human societies, they also have driven significant environmental changes which are beginning to have noticeable impacts worldwide, including climate change, the BP oil spill, and Japan’s nuclear crisis. What can we learn from the Jewish tradition about how to use energy responsibly? 

Use Energy Wisely

 

The Jewish tradition teaches us to use energy wisely. In some cases, wasting energy is a violation of Bal Tashchit, the prohibition not to waste excessively.[2]For example, the Talmudic Sage Mar Zutra stated, “One who covers an oil lamp [causing the flame to burn inefficiently] or uncovers a kerosene lamp [allowing the fuel to evaporate faster] violates the prohibition of Bal Tashchit.”[3]

Based on this teaching of the Talmud, the Ben Ish Chai (Rabbi Yosef Chaim ben Eliyahu), a major halakhic authority of 19th century Iraq, addressed a related case in which a person lit two wicks in oil for use at night. The person left both wicks lit throughout the night in the event they woke up in the middle of the night and needed to see. In order to prevent waste, the Ben Ish Chai instructed the person to extinguish one wick before going to bed, since were they to get up they would only need the minimal light of one wick and keeping the second wick lit would be a transgression of Bal Tashchit, the prohibition not to destroy or waste.[4] This halakhic responsa shows a high degree of concern for the wasting of energy and the unnecessary use of oil, in a case where a person does not derive benefit from the additional use of energy.  

Similarly, the Ben Ish Chai discusses a case in which a person puts a large amount of oil before Shabbat in a lamp in their home in order for it to remain lit for all of Shabbat. He rejects this practice as a waste of oil and a transgression of Bal Tashchit, since the light from this lamp will not be of benefit to a person during the day in their sun-lit home.

In our time, this responsa may be relevant concerning leaving lights, heaters, air conditioners, or other appliances running for all of Shabbat or during the week when a person will not derive benefit from them. Doing so for a significant portion of the time may be considered a violation of Bal Tashchit.

Another area where this may apply is in 'standby' appliance use in most homes. According to the Energy Analysis Department of the Lawrence Berkeley National Laboratory, “A surprisingly large number of electrical products—TVs to microwave ovens to air conditioners—cannot be switched off completely without being unplugged. These products draw power 24 hours a day, often without the knowledge of the consumer. A typical American home has forty products constantly drawing power. Together these amount to almost 10% of residential electricity use.”[5]

If the Ben Ish Chai was concerned about the unnecessary use of one wick in an oil lamp, how much the more so should we be concerned about dozens of appliances that quietly, constantly use energy without benefiting the user?

 

For Our Health

 

Modern energy use causes pervasive air pollution in most of the major cities in the world. The pollution comes from many sources, including motor vehicles, industrial factories, and power plants that produce electricity for lighting and appliances at homes and offices. Studies show a correlation between air pollution and premature deaths due to lung cancer. Researchers conclude that when air pollution in a city declines, the city benefits with a directly proportional drop in death rates.[6] According to 2008 estimates from the World Health Organization, “air pollution is a major environmental risk to health and is estimated to cause approximately two million premature deaths worldwide per year.”[7] A joint Israeli-US study found that more people die in Israel from air pollution than from traffic accidents (which is also more than who die from terrorist attacks).[8]Researchers also note that air pollution can trigger depression, anxiety and anger in some people.[9]

How does Jewish tradition recognize the importance of protecting our health from the impacts of air pollution?  One example involves the Mishnah stating that tanneries, which produce noxious odors, must be sufficiently distanced from human settlements so as not to negatively affect people in the vicinity.[10]Rabbi Ezra Batzri, former head of the Sephardi Rabbinical Court in Jerusalem, writes that causing harmful forms of pollution to others is “not to be considered as inconsequential. [Rather] they are matters of Jewish law that stand up at the heights of the world.” He notes therefore that a character trait of a righteous person (Midat Hasidut) is being careful about not damaging others even indirectly.[11]

By using less energy, we can reduce the amount of coal and gasoline burned, and reduce the health impacts from the resultant air pollution.  Given the significant damages to human health, it would seem that the unnecessary or wasteful use of energy goes against rabbinic advice concerning not damaging other people.[12]

 

Green is Clean: Keeping Cities Beautiful and the Air Clear

 

Keeping cities beautiful is not only a modern challenge-- in Talmudic times, the Sages enacted legislation to maintain the beauty of the cities of the land of Israel. The Mishnah states that trees had to be distanced from city walls, which according to the Talmudic sage Ulah was to preserve the beauty of the city.[13]This source indicates how maintaining a city's beauty is a significant concern in the Jewish tradition. The Talmud discusses how large ovens were not allowed in Jerusalem, lest the smoke from the ovens blacken the walls of the Holy City and make it less beautiful.[14] Furthermore, the Mishnah prohibited using olive wood, grapevines and fruit-bearing fig trees and date palms for burning in the Temple in Jerusalem, which according to some rabbinic views was because they produced excessive smoke.[15] Jerusalem had the highest level of sanctity of all cities in the Land of Israel, and which required that its physical beauty, including air quality, be preserved.

Within its walls, G-d commanded the priests to raise up a pleasing aroma through the burning of incense at the Temple in Jerusalem.[16]  The Talmudic sage Rabba bar bar Chana taught that the pleasant smell of the incense reached all the way to Jericho, over ten miles away. The air was so fragrant that women did not need to put on perfume. In Jerusalem, the smell of incense was so strong that a bride, known for wearing strong perfume, would not need to put any on.[17]This Talmudic teaching conveys that pleasant fragrance was the dominant smell in Jerusalem, stronger than anything else that was put into the air.

In our times, Jerusalem is blessed with the pleasing smell of many bakeries and flower shops. Yet many thoroughfares also smell of air pollution, due to exhaust fumes of carbon monoxide, sulphur dioxide, and other not-so-pleasing air pollutants. In 2007, Jerusalem experienced 33 high air pollution days, due in large part to the personal and industrial energy use of its 750,000 inhabitants.[18] Beyond Jerusalem, a thick layer of smog often hangs over the coastal plain of Israel from Ashkelon to Netanya and blemishes the beauty of the land of Israel.

While the rabbinic laws to preserve the beauty of Jerusalem and Israel's cities are for the most part not in force today, we would be wise to consider their wisdom for our current situation. By reducing and cleaning our energy use, we can preserve the sanctity of our holiest city and the land of Israel.  These lessons can also lend wisdom for the health and beauty of cities outside of Israel.[19]

 

Shabbat, Fire, and Energy

                

When we speak about human energy use today, we are primarily speaking about our use of fire. Fire is the paradigmatic technology, which human beings use to master the world. Fire enabled metallurgy, the shaping of mineral ores into tools, which over human history have become more and more advanced.  Today we have a lot of machines which rely on fire: internal combustion engines in our cars, power plants that produce electricity, and lights and appliances in our homes and offices that run on electricity. The tremendous wealth of modern society stems from the use of industrial technology powered by fossil fuels that have been ignited by fire.

Rabeinu Bachya (Spain, 1255-1340) teaches that “Fire, i.e. light, was the first of the activities G'd engaged in when creating the universe.”[20]  He also notes that "Making fire is an appropriate example of basic human activity seeing that most of the principal activities we are engaged in cannot be performed satisfactorily if one were not able or allowed to make fire.” For six days we are supposed to properly use fire, which represents human mastery over the world.

The Torah teaches, “You shall not kindle fire in any of your dwelling places on the Sabbath day.”[21]  On Shabbat, we are instructed to refrain from using fire, demonstrating that true mastery belongs to G-d alone.  As Rabbi Sampson Raphael Hirsch teaches, “…the ability to produce fire artificially is just that which first gave Man his true mastery over the materials of the world. Only by means of fire can he create his tools.”[22]Rabbi Hirsch explains, “On Sabbath the cessation of work is the belief and acknowledgment that the ability to 'master matter,' the creative productive power that Man has, is lent to him by God, and is only to be used in His service.”[23]

We mark the entrance and exit of Sabbath by lighting candles, and on the seventh day itself rest from using fire. Shabbat is the prime way that a Jew is supposed to learn balance in how to use fire, and by extension, energy and technology. According to traditional Shabbat observance, there is rest from cars and computers, Blackberries and cell-phones, stereo music, trains, and alarms.[24] By bringing some of this rest into our world today, we can reduce the amount of energy we need and also help us put ourselves in correct relationship with our use of energy.[25]

Global Impacts

 

Fossil fuels power our industrial society, and this energy use has significant impacts, including global climate change. A typical American household consumes over 12,000 kilowatt-hours of electricity per year. Each kilowatt-hour of electricity from a coal-fired power plant releases over two pounds (nearly 1 kilo) of carbon dioxide (CO2).[26] Per capita energy consumption in Israel, while below that of the US, is on the rise. Burning wood, coal, and oil lets off carbon dioxide. Carbon is stored in these fuel sources, and through the combustion process of fire, carbon connects with oxygen from the air to form CO2.[27] This CO2, along with other ‘greenhouse gases,’ is contributing to global changes in the earth’s climate. Burning fossil fuels is heating the planet, melting the ice caps, raising the sea level, and making forest fires more common.

A consensus of international scientists—i.e. the mainstream in science-- state that human-caused global climate change is likely to bring on more severe heat waves, storms, floods, and droughts, with major impacts on human societies.[28] A 2011 major study “directly links rising greenhouse-gas levels with the growing intensity of rain and snow in the Northern Hemisphere,” adversely impacting hundreds of millions of people.[29] Leading climatologists stated “with a high degree of confidence” that the extreme heat waves like those that occurred in Texas and Oklahoma in 2011 and Moscow in 2010 “were a consequence of global warming.”[30] In Hurricane Sandy of 2012, a number of scientists partially attribute to climate change the strength of the storm surge that caused widespread destruction in New Jersey and New York.[31]

 

Toward Sustainable Energy Use

 

One way we can reduce the impacts of our use of fire is to use more renewable energy. In 1981, the Lubavitcher Rebbe made a call to significantly increase the use of solar energy in the United States. He said, “Very soon, the entire country should switch, first of all, to energy that can be generated from the sun's rays in the [US] south, which should be supplied to the entire country.”[32] His call to use renewable energy is relevant today more than ever. Solar energy utilizes fire in a different way, by making use of the tremendous energy reaching the earth from the fire that is the sun. For example, solar water heaters harness the sun's rays to heat water and thus reduce electricity demand. The Good Energy Initiative works to provide financial incentives to poorer families in Israel to use solar water heaters instead of conventional heaters that rely on burning fossil fuels.[33]

An individual might say to him or herself: 'But I am just one person—my consumption has a negligible effect on the global climate. There are 6.9 billion people in the world[34] and 10.5 million people in Israel—my using energy wisely won’t make a difference!' This way of thinking goes against the advice of the Sages, who said that a person needs to act as if the entire world was created for them.[35]

An individual can make a difference by using less energy, i.e., by driving less, eating less meat or  globalized food, or taking fewer plane trips. It is in this realm of personal consumption that Jewish thought may best inform our energy and climate challenges today and empower us to change. Bal Tashchit of energy, protecting the health of our neighbors, maintaining the beauty of cities, and not making fire on Sabbath all have in common the restraint of individuals to achieve a higher purpose. These teachings instruct us about prudent, conscious, and elevated use of energy. Energy is a precious resource that must be used wisely. If not, its misuse has serious consequences for people and the planet.

 

The prophet Isaiah repeatedly calls on the Jewish people to be a “light unto the nations.”[36] Rabbi David Kimchi explains that 'light' here refers to the Torah.[37] In our times, let us find inspiration and light in the profound teachings of our tradition that address our central challenges. And let the light that emerges from our example reveal to the world a new sustainable path.

He also explains that Maimonides did not mention this case of wasting energy in his writing on Bal Tashchit because he may have found this case to be obvious and therefore implicitly included through mention of the other cases (water, clothing, etc). In addition, Rabbi Forehand argues that the wasting of oil occurs as a direct consequence of the person's action (p. 348).

[24]The halakhic permissibility of using electricity on Shabbat is based onpikuach nefesh [saving a human life]: since we need electricity for emergency and security services, we can use it generally for other needs in a passive sense. For a 250-page exploration of Jewish law in relation to electrical appliances, including refrigerators, alarm systems, dishwashers, and elevators, see Shabbat and Electricity, by Rabbi L.Y. Halperin, compiled by Rabbi Dovid Oratz, Institute for Science and Halacha: Jerusalem, 1993. A disagreement existed for many centuries between the Karaites and rabbinic Judaism starting in the eight century concerning whether can have fire burning on Shabbat. The Karaites understood the command 'don't kindle fire' as 'don't use fire.' The Rabbis saw the prohibition as not 'lighting' fire, and not about not using fire at all.
