Baggage-laden biofuels

By

Sept. 2, 2012   Leave a Comment  

Biofuels (or agrofuels) can be a carbon-neutral energy source, but the overall process of producing them is far from carbon neutral, given the substantial amount of fossil fuels expended in growing, harvesting, processing and distributing them. (Hemera Collection)

Are there safer sunscreens?

By

Sept. 2, 2012   Leave a Comment  

Most of us assume that all we need do to prevent sunburns and skin cancer from exposure to the sun is to slather on sunscreen. But consumers should be careful about which sunscreens they trust for themselves and, even more important, for their kids.

Are there alternatives to conventional, energy-hogging air conditioners?

By

July 21, 2012   1 Comment  

The chlorofluorocarbon coolant widely used in air conditioners through the 1980s was phased out because it was damaging the Earth’s protective ozone layer, but the chemicals that replaced it are some 2,100 times stronger as greenhouse gases than carbon dioxide. We may have saved the ozone layer, but -- whoops! -- there goes the climate.

Can anything be done?

By

LED bulbs appear poised to displace compact fluorescents (CFLs) as the king-of-the-hill of green bulbs, but a study published in late 2010 in the journal Environmental Science and Technology found that LEDs contain lead, arsenic and a dozen other potentially dangerous substances. (Thinkstock)

In a plan formulated by the Obama administration, auto makers will double the average, unadjusted fuel-economy rating of their cars and light trucks to 54.5 miles per gallon by 2025 from today’s standard of 27 miles per gallon. Congress is likely to sign the new rules, which will start taking effect for the 2017 model year, into law this summer. (ThinkStock)

Water usage in the bathroom

By

Jan. 24, 2012   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, 2012   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)
