Water usage in the bathroom

By

Jan. 24   Leave a Comment  

Some 60 percent of our household indoor water usage happens in the bathroom. Toilets are the biggest water hogs, with older models using as much as eight gallons per flush. A shower, even with a low-flow shower head, can use up to 40 gallons of water, and a bath can use up to 50-60 gallons. (Thinkstock)

Analysis: Cutting down forests for biomass fuel

By

Jan. 24   Leave a Comment  

In theory, burning any kind of plant material for energy is a carbon-neutral endeavor, but chopping down forests for ethanol is unwise because they cannot be regrown quickly. And tree plantations don't provide the clean water, storm buffers, wildlife habitat and other ecosystem services that natural forests do. Pictured: A wood biomass plant. (Thinkstock)

Report: Asthma rates on the rise

By

Dec. 17, 2011   Leave a Comment  

Asthma rates have doubled since the 1980s, in spite of air quality in U.S. cities having increased over the same time period. This has led some experts to conclude that other factors -- including Vitamin D deficiency, obesity, overuse of acetaminophen (i.e. Tylenol) and spray mist from glass cleaners and air fresheners -- are now playing a role.

Can using thorium instead of uranium make nuclear energy safer?

By

Nov. 26, 2011   Leave a Comment  

Advocates of thorium to power nuclear plants say that the element is safer than uranium, and that its waste cannot -- like the plutonium waste of uranium fission -- be re-formulated for nuclear weapons. Thorium plants, they say, also wouldn't need containment domes like those pictured here because the reactors can't "melt down" and release radiation. (iStock)
