For many proponents of keeping the status quo, that is, sticking with fossil fuels for our energy needs, a common claim will be, “Fossil fuels are cheaper than renewable energy.” This may have been true twenty years ago, or...
Big oil companies count on our refusal to change when it comes to fuel-efficent vehicles. “Fuel efficient vehicles are wimpy” and “Fuel-efficient vehicles aren't cool” might sum up the attitude of both consumers and dealers everywhere. This attitude seems...
A few quick notes about hydrogen. As an element, it is the simplest, lightest, and most abundant on this planet that we call home. Also, when it is pure, which rarely happens naturally, hydrogen is highly combustible. When it...
Most climate change scientists will agree that one of the biggest factors effecting the phenomenon is carbon dioxide emissions, which have jumped significantly since the beginning of the Industrial Age about 200 years ago. Our main energy sources remain...
Modern photovoltaic solar panels are not very efficient converting solar energy into electricity. They need to convert solar energy, which is inherently alternating current , into direct current , which then requires further electronics, an inverter, to convert DC...
A study conducted by Professor Peter Cox from University of Exeter, England, published in the latest issue of Nature, reveals that the Amazon forest is not likely to disappear due to rising temperatures, because carbon dioxide in the atmosphere...
Imagine how much electricity is required to sustain a supermarket with numerous rows of refrigerators and hundreds of lamps that light up the huge space. Statistics show that big supermarket chains use around ten times the energy of a...
A team of chemists at University of Burgos in Spain have produced a sheet that acts similarly to litmus paper, but it changes its colour in the presence of water contaminated with mercury. And if being able to see...
A study conducted by a team of researchers from Rice University, University of Tokyo, the University of British Columbia, the California Institute of Technology, Texas A&M University and Pomona College, suggests that the shifts in weather patterns and temperature...
Forrest Gump knew all about the "shrimpin' business" from his friend Bubba, but at that time I guess he didn't know how to get rid of the shrimp shells in an environmentally-sound way. Scientists today want to convert these...
