Things that aren’t the way some people believe


Booming European Offshore Wind – Also Good for Marine Life

Written by , on January 19, 2010

Despite continuing difficulties getting funding for large projects, Europe’s offshore wind power generating capacity grew by 54% in 2009. A total of 199 wind turbines, with a combined capacity of 577 megawatts, were installed at eight new offshore wind farms connected to the European grid in 2009.   The European Wind Energy Association expects ten more […]  Read more »

Will Himalayan Glaciers Disappear by 2035?

Written by , on January 18, 2010

In its 2007 report, the Inter-governmental Panel on Climate Change (IPCC) said: “Glaciers in the Himalayas are receding faster than in any other part of the world and, if the present rate continues, the likelihood of them disappearing by the year 2035 and perhaps sooner is very high if the Earth keeps warming at the […]  Read more »

Study: Capturing CO2 or Using Nuclear Power Will Not Stop Global Warming

Written by , on July 15, 2009

According to scientists at Luleå University of Technology in Sweden, attempting to tackle global warming by capturing carbon dioxide or switching to nuclear power will not work because a large part of the warming results from the heat produced by industrial processes rather than the greenhouse effect. In a paper published in the International Journal […]  Read more »

US Coal Reserve Estimates Drastically Reduced

Written by , on June 14, 2009

The U.S. Geological Survey has reported that economically extractable coal reserves in the United States, typically estimated at some 240 years worth, could be substantially less than previously thought – perhaps only half the previously estimated reserves. The news is consistent with the findings of a 2007 National Research Council study and is similar to […]  Read more »

Compact Fluros and Mercury

Written by , on February 11, 2009

Compact fluorescent light (CFL) bulbs do contain mercury, which is a harmful substance – but does that mean that they worse than incandescent light bulbs? According to the US Environmental Protection Agency:, CFLs contain an average of about 4 milligrams of mercury sealed within the glass – that’s less than one percent of the mercury […]  Read more »

Coal Reserves May Be Overestimated

Written by , on December 18, 2008

Dave Rutledge, chair of the California Institute of Technology’s Engineering and Applied Sciences Division, has produced a new calculation of the world’s coal reserves which is much lower than previous estimates. According to Professor Rutledge’s model, the total amount of available coal, including all of the coal already mined, is only 662 billion tonnes. In […]  Read more »

The Baseload Myth

Written by , on September 11, 2008

A year or two ago, the fossil fuel industry was adamant that renewable energy sources could never provide baseload electric power. Although most experts now admit hat this is not the case, the claim that renewables cannot supply baseload is still sometimes made and needs to be examined. Baseload is the minimum level of power […]  Read more »

What’s Wrong with Beef?

Written by , on August 24, 2008

According to a United Nations report, cattle are “responsible for 18% of greenhouse gases, more than cars, planes and all other forms of transport put together.” But why are cattle so bad? And are other sources of meat equally bad? There are about 1.3 billion cattle occupying 24% of the world’s entire land area. Cattle […]  Read more »

“60 Minutes” Global Warming Skepticism

Written by , on August 17, 2008

Australia’s “60 Minutes” has broadcast an item called “Crunch Time” which made much of the opinions of David Evans, a computer programmer with a PhD in electrical engineering who once worked on a mathematical modeling program for the Australian Greenhouse Office. Dr Evans put two arguments to support his view that global warming is not […]  Read more »

Population Myths

Written by , on August 13, 2008

A recent article published by the Yale School of Forestry and Environmental Studies has debunked a number of myths about population growth. Myth: Population growth rates only decline as countries become wealthy and women become educated. While it is well true that population growth rates have declined most, often below replacement levels, in the wealthy […]  Read more »
