Cuba’s foray into offshore oil drilling

March 10   Leave a Comment  

Finding significant off-shore oil reserves could turn Cuba into an oil exporter, possibly even thawing relations with a still oil-hungry U.S. Pictured: The Scarabeo 9 oil rig while still under construction in China in 2009. It is now 30 miles off of Cuba's coast and just 60 miles south of the Florida Keys. (Wikipedia)

New automobile fuel economy standards

Feb. 19   Leave a Comment  

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)

Laboratory tests found high levels of BPA on 40 percent of thermal paper receipts sampled from major U.S. businesses and services, including McDonald’s, Chevron, CVS, KFC, Whole Foods, WalMart, Safeway and the U.S. Postal Service, among others. BPA in paper receipts also contaminates paper recycling and is showing up in napkins, toilet paper and other common papers with recycled content. (Thinkstock)

How much energy is used by cable TV boxes?

Feb. 1   Leave a Comment  

Set-top boxes in the U.S. consume 27 billion kilowatt-hours of electricity each year, equivalent to the annual output of six coal-fired power plants. Part of the reason is that they typically operate at nearly full power even during the two-thirds of the time when they are not in use. (Thinkstock)

Short answer: A lot

Fact: Carbon emissions are making our oceans acidic

Feb. 1   Leave a Comment  

Ocean acidification is likely to affect the ability of some shellfish to produce and maintain their shells. This process will not only wreak havoc on the shellfish we eat, but also on smaller marine organisms that are key components of the lower end of the marine food chain. (Thinkstock)

Water usage in the bathroom

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

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

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.

Are green walls the next big thing in environmental tech?

Nov. 26, 2011   Leave a Comment  

Green walls, or "vertical gardens," are walls partly composed of or filled in with live plant matter. They filter air and water, soak up carbon dioxide and help lessen the “heat island” effect of urban areas while reducing air conditioning costs in their host buildings. Pictured: a vertical garden at the Anataeum Hotel in London. (Media credit/Niall Napier via Flickr)

Can using thorium instead of uranium make nuclear energy safer?

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)
