Biodiesel

Though biodiesel is still an infant industry, it serves as a reasonable alternative energy source to petroleum. Most cars in the United States have gasoline engines, but Mr. Thompson suggested that a diesel engine transition would benefit the environment in the long run. Of course this would be the case only if biodiesel were used [...]

Hydrogen Energy

Hydrogen Energy is created by passing Hydrogen through a membrane which separates the protons and electrons. In this process, the electrons are diverted to create electricity and H2O is given off as a byproduct. As a fuel source, Hydrogen is clean, with practically no pollutants released, it is efficient, can be up to 90% efficient [...]

Intro to Solar Energy

Why use solar energy? Lots of reasons. Unlike burning fossil fuels, solar energy is waste-free and results in zero emissions into the atmosphere. It is also a renewable resource, and can be relied on to last as long as the sun does. Despite the initial costs of solar technologies, the use of solar power saves [...]

Wind Energy

Wind Energy, put simply, is using the wind to move turbines, which then in turn provide power. The turbines are mounted atop very tall towers in order to capture the most wind. This is by far one of the most sustainable and cleanest types of energy available. The wind turbines produce no toxic or heat [...]

Intro to Geothermal Energy

*Note: SargeK moved to the other class, but since we have no one to do geothermal, here is a guess post by him. Geothermal Energy is essentially using the earth’s natural heat for power. One way the process works is the heat from the earth warms water, which evaporates to steam. The steam is then [...]

Hydroelectric Energy (Conventional)

Published by under JoeY,Mr. W,Unit 12-Energy

Currently, about one-fourth of the world’s electricity comes from hydroelectric energy. Humans have created dams and hydroelectric power plants all over the world in order to harness the energy in rivers to produce electricity. The method in which the dam produces electricity is pretty simple: The dam blocks the flow of the river, flooding the [...]

Intro to Biomass Energy Sources

*Note: Since no one took biomass fuels in our smaller class, here is an intro post from AnnaSB in the other: To understand what biomass energy is, first one must know what biomass is. Biomass is defined as the total mass of living matter in a given unit of environmental area. http://i484.photobucket.com/albums/rr209/videotellem/types-of-biomass.jpg Biomass energy is [...]
