Green Energy Revolution What does it mean and how does it work?

Green Energy Solutions As stewards of the planet, this generation must implement and maintain the transition to Green Energy This presentation is meant to give learners an opportunity to explore the many green energy technologies available Students will learn about green energy and create a presentation of their own on one source of clean energy and present it to the class

Types of Green Energy Wind Solar Hydroelectric Biofuels Geothermal

Wind Energy Resources Wind power is harnessed by huge windmills. In the realm of renewable energy these are called turbines. They catch the wind, turn the blades of the turbines, and that energy is converted to electricity. Wind is already being used across the U.S. Check out this website for more information http://www.windpower.org/en/kids/index.htm

Solar Energy Resources The Sun is our most valuable resource. The Sun is the source of all energy on Earth. Without the Sun, the Earth would not exist. Solar power has been around for a long time and new technologies are allowing for more efficient use of this abundant resource.

Hydroelectric Power Resources When water moves it is using energy. Hydropower plants can harness that energy and use it for electricity to power our homes, schools, and businesses. The Hoover Dam in Nevada has been in operation for many years.

Biofuel Energy Resources “Biodiesel is a liquid fuel made from vegetable oils, recycled cooking grease, and animal fats. In the United States, most biodiesel is made from soybean oil, whereas in Europe, rapeseed oil (canola) is the commonest feedstock. Biodiesel is made through a chemical process called transesterification, a process in which the oil reacts with alcohol in the presence of a catalyst leaving behind two products - methyl esters (biodiesel), and glycerin (a valuable byproduct used in soaps ).” (http://www.bnl.gov/est/erd/biofuel/) To learn more, check out this website:

Geothermal Energy Resources Geothermal energy uses the steam and hot water produced within the Earth to produce electricity, then replaces the water to be reused Geothermal wells reach 1-2 miles into the Earth’s crust To learn more, check out these websites: http://eia.doe.gov/kids/energyfacts/sources/renewable/geothermal.html#Environment http://iga.igg.cnr.it/geo/geoenergy.php
