The destructive potential of one of nature's most destructive forces, the hurricane, is compared to one of human's most destructive devices, an atomic bomb. Both can create near absolute devastation at "ground zero". However, how do they really compare in terms of destructive energy? This discussion compares the energy, the…

In this article, a number of future energy visions, especially those basing the energy systems on hydrogen, are discussed. Some often missing comparisons between alternatives, from a sustainability perspective, are identified and then performed for energy storage, energy transportation, and energy use in vehicles. It is shown that it is important…

A photovoltaic panel can convert sunlight directly into electricity. If one connects enough of them in a series-parallel arrangement called a solar array, they can provide about half of a home's annual electricity needs. The panels comprise specially treated electronic materials that when exposed to sunlight will give up electrons freely, and…
