7. Energy for Lighting

   

2006

May 2006. Try A Solar Water Heater. Andrew Korfhage. Coop America. With a solar water heater, you'll get the hot water your household needs while saving money and energy and reducing your dependence on coal-fired power. After a year with their solar hot water heater, homeowners Bob Allen and Lyle Rudensey say they'll never go back to relying on a conventional water heater. Even in gloomy, rainy Seattle, they are saving money and energy by heating all of their water with the power of the sun. "With a lack of leadership at the federal level, I feel it's very important that we all do what we can to reduce our dependence on fossil fuels and reduce greenhouse gases," says Lyle. "Solar hot water systems are a great place to start. They're not as expensive as solar photovoltaics, and they'll save you substantial amounts of energy and money." ...With all their savings combined, Lyle points out that his and Bob's electric bills have dropped to a low of $5. "Plus, the water heater increased the value of the house," Bob adds. "And it's a hedge against future energy cost increases." ..."Some people might think that solar water heaters aren't worth installing in a climate like the Pacific Northwest, but that's not true," says Lyle. "Germany gets about 70 percent as much sunlight as Seattle does, and they are the biggest users of solar power in the world. This is something everyone can do that really makes a huge difference."

2006 Spring. California Illuminates the World. By Craig Canine, OnEarth Magazine. Excerpt: ...Leading-edge policies and technologies that encourage efficiency have long been a California export.... Energy policy makers in other states as well as in the federal government look to California's energy-conservation measures the same way political analysts view the New Hampshire presidential primary -- as a bellwether for the nation. California was, for example, the first state to adopt efficiency standards for appliances. These went into effect in 1977 and were upgraded throughout the 1980s. Florida, Massachusetts, Connecticut, New York, and other states followed California's lead, sometimes copying the California code verbatim. This shift at the state level convinced appliance manufacturers to join with efficiency advocates in lobbying for a uniform national standard, which Ronald Reagan signed into law in 1987. Thus began a process that continues to repeat itself. Since 2004 several other states have adopted at least some of California's latest standards, many of which also wound up in last year's federal energy bill. "The general pattern," says Devra Wang, a staff scientist at the Natural Resources Defense Council, "is that California adopts new standards, other states follow, and then they're adopted at the federal level."
California's efficiency standards for new buildings, introduced in 1978 and known as Title 24, have been replicated all over the world. The code governing new construction in Russia, for example, is cutting energy use by more than 40 percent, thanks to California. A similar effort now under way in China could wind up as California's most enduring global legacy.... If the planet is to tackle the twin challenges of finding adequate energy resources to drive hungry economies while averting the worst consequences of climate change from burning fossil fuels, the West Coast is the place to look for leadership....

15 February 2005. Turning On the Lights Where Electricity Is Rare By ANDREW C. REVKIN. NY Times. It will be years before many of the 1.6 billion people still cooking, studying and working by the flickering light of kerosene lamps get on the grid, so engineers are trying in the meantime to improve on an existing improvised transmission system for electricity in poor rural areas - battery brigades. In many parts of Africa, for example, the first source of electricity has been car batteries, which are lugged every few days to towns to be recharged from diesel generators in ways that often shorten battery life and at rates that are 20 to 30 times as high as those paid by Americans.... A team led by Dr. Vijay Modi, the chairman of Columbia's mechanical engineering department, has built a lunchbox-size battery pack and plug-in fluorescent fixture that can supply four hours of light to a household each night while consuming just one kilowatt-hour per month. "In the U.S., an average home consumes this much electricity in a little less than one hour," Dr. Modi said.

October 2004. A good lab activity on inverse square/light intensity called "Shedding Light on the Inverse Square Law", pages 44-48, Science Teacher Magazine, NSTA, October 2004, Vol 71, #8 [suggested by Eloise Farmer]

January 8, 2004. Let There Be L.E.D.'s. By IAN AUSTEN. NY Times. IT started innocently enough. Marcel Jean Vos, an interior and commercial designer in London, bought some light-emitting diodes to create a small lighting system in the kitchen of his apartment. Now, four years later, Mr. Vos has transformed a neighboring one-bedroom apartment into a space lighted entirely with L.E.D.'s, the solid-state technology more commonly associated with the tiny lights on electronic gadgets.
