Get the Family in on the Energy-Saving Act
It’s no wonder that many of Earth Day’s most ardent supporters are children. Environmental education is growing into a fixture in classrooms across the United States. Students are often eager to put their lessons in sustainability into practice at home. In turn, children are often the ones to push their parents towards energy efficiency. Influential […]
Hydrogen still in the eco-car race
(AP) — Hydrogen, one of Earth’s most abundant elements, once was seen as green energy’s answer to the petroleum-driven car: easy to produce, available everywhere and nonpolluting when burned. Hydrogen energy was defeated by a mountain of obstacles – the fear of explosion by the highly flammable gas, the difficulty of carrying the fuel in […]
