Green Promise Seen in Switch to LED Lighting



"..fast-growing trend that is redefining the century-old conception of lighting, replacing energy-wasting disposable bulbs with efficient fixtures that are often semi-permanent, like those used in plumbing.

Studies suggest that a complete conversion to the lights could decrease carbon dioxide emissions from electric power use for lighting by up to 50 percent in just over 20 years; in the United States, lighting accounts for about 6 percent of all energy use. A recent report by McKinsey & Company cited conversion to LED lighting as potentially the most cost effective of a number of simple approaches to tackling global warming using existing technology."

Why the era of cheap food is over

Image
Christian Science Monitor Food prices worldwide hit record highs in 2006, and all the signs are that they will go on rising this year, and for the foreseeable future. The era of cheap food, the experts say, is over and we are going to have to get used to it. This is easier said than done for millions around the world, as evidenced by protests in Mexico over the cost of corn tortillas, and in Italy last September about the price of (wheat) pasta. Staff writer Peter Ford looks at why. Read more....

Climate Confusion: Who Wins?

Image
by Michael O'Brien Climate change is the biggest challenge we face as a humans. Any serious student who analyses the information recognizes that the overwhelming consensus from scientists is that we have a very small period of time in which our efforts will have a positive impact for our planet and our children's future. For the past 10 years or so, there has been rigorous debate both by the scientific community and in the press about climate change. The debate is over, the issues have been discussed and now is the time for us to take responsibility for our future. It is fascinating to watch the media feel the need to present the “other side” of this issue when there is discourse about climate change. My guess is that they feel vulnerable from the vocal skeptics or right wing talk show hosts so they include a dwindling number of scientists or spokespeople who argue against human causation. It seems there is an inordinate amount of air time devoted to this topic in proportion...

US headed for a massive decline in carbon emissions

Image
For years now, many members of Congress have insisted that cutting carbon emissions was difficult, if not impossible. It is not. During the two years since 2007, carbon emissions have dropped 9 percent. While part of this drop is from the recession, part of it is also from efficiency gains and from replacing coal with natural gas, wind, solar, and geothermal energy. The U.S. has ended a century of rising carbon emissions and has now entered a new energy era, one of declining emissions. Peak carbon is now history. What had appeared to be hopelessly difficult is happening at amazing speed. For a country where oil and coal use have been growing for more than a century, the fall since 2007 is startling. In 2008, oil use dropped 5 percent, coal 1 percent, and carbon emissions by 3 percent. Estimates for 2009, based on U.S. Department of Energy (DOE) data for the first nine months, show oil use down by another 5 percent. Coal is set to fall by 10 percent. Carbon emissions from burning all fo...
