"The geothermal power production in the U.S. today provides enough electricity to meet the electricity needs of about 2.4 million California households. (1) This does not include contributions from geothermal heat pumps and direct heating uses."

When sunlight strikes a solar cell, electrons are knocked loose. They move toward the treated front surface. An electron imbalance is created between the front and the back. When a connector, like a wire, joins the two surfaces a current of electricity occurs between the negative and positive sides

Transesterification - Definition, Glossary, Details - Oilgae - 0 views
-
The main reaction for converting oil to biodiesel is called transesterification.
-
The transesterification process reacts an alcohol (like methanol) with the triglyceride oils contained in vegetable oils, animal fats, or recycled greases, forming fatty acid alkyl esters (biodiesel)
What Is Biodiesel - 0 views
-
The Transesterification process is the reaction of a triglyceride (fat/oil) with an alcohol to form esters and glycerol

When a visible light photon strikes a solar cell it can do one of three things: pass straight through, be reflected, or be absorbed. If the photon is absorbed, its energy is absorbed by an electron in an atom of the solar cell enabling it to escape from its normal position (photon excitation), cross the junction and fill a hole. Since electrons are physically moving across the PN junction, the positive charge carrying holes are effectively moving in the opposite direction around the load circuit (a rechargeable battery or light bulb etc). This completes the circuit providing more holes for the electrons to combine with and providing usable electricity.
Biofuel Guide - Introduction to Ethanol and Biodiesel - 0 views

First generation biofuel are those fuel derived from vegetable or animal fats/oils, starch or sugar with the use of modern technology.

Gallons per acre In the perspective of land use and agricultural efficiency, ethanol seems to be a good choice. The reason is that about 420 gallons of ethanol can be generated per acre in contrast to 60 gallons of biodiesel per acre soybeans. Consequently, the cost of soybean oil would significantly increase if biodiesel production is increased as well.

1. Let the base organic material (corn, sugarcane, wheat, etc) pass through a grinding meal to pulverize the selected material. 2. Then, liquefy it by placing the blend of water, grain powder and an enzyme that facilitates the breakdown of the grain compound into a high-heat cooker. 3. Cool it afterwards. Add another enzyme that will facilitate the conversion of starch into sugars which are then fermented, producing alcohol from the cooled mash. 4. Start the fermentation by adding yeast to the sugar mixture. The sugars will be broken down to ethanol (a form of alcohol) and carbon dioxide. 5. Distill the fermented mixture in order for the ethanol to separate from the solids. 6. Get rid of the water from the separated ethanol through a dehydration process.

"Cellulose ethanol production is newly discovered experimental processes which can breakdown cellulose in woody fibers. This would only mean that through this method, ethanol from crop wastes, trees and grasses can be derived. It is significantly better since trees and grasses require small amount of energy in comparison to grains that must be replanted annually. "
