BioFuels, The Answer to High Fuel Prices

Biofuels, simply put, are fuels that are derived from agricultural products. Biofuels are a renewable source of energy that can be used in many applications, from fueling your vehicle, to generating electricity and heating your home.Recently, biofuels have been attracting attention from various sectors. Biofuels are considered to be 'carbon-neutral', which simply means that the amount of carbon dioxide which is created when burned, is equal to the amount of carbon dioxide used during growing. It is hoped to be a 'green' alternative to petroleum, which has generated a lot of interest from investors and different countries around the World.
Types of BioFuelsEthanolEthanol is a fuel derived largely from corn and sugar cane, although it can also be made from other sources of sugar as well.Currently, ethanol is largely used as an additive to Gasoline, which could cut are dependence on foreign oil, and has the potential to replace gasoline altogether.Ethanol can also be 'home-brewed' and there are many products available online to assist an individual in that dream of brewing their own gas.
Ethanol, does however face some hurdles before it becomes a true replacement for Oil. Considerations such as food supply should take precedence, as much of the stock that is used is derived from food sources. With expected production to e in the billions of gallons, we must take care not to create more problems in the future than solve them. Ethanol can be made from plant sources without starving people, but this will take research and commitment on the part of Government and Industry officials
BioDieselBio diesel is a term used to describe various types of esters derived from vegetable oils. The most common is rape seed oil, however other oils can e used. Some examples are waste vegetable oil from a fryer, soybean oil, sunflower oil and palm oil. Bio diesel is usually made from either the methyl ester or ethyl ester of the base oil.
Bio Diesel use around the World varies. In Brazil, a country already with a huge lead, recently opened a bio diesel refinery, further lessening it's dependence on Oil. In the U.S., Bio Diesel is becoming an attractive alternative due to rising Gas prices. Bio Diesel's biggest impact would be in the transportation sector, but it can also be applied to any machine that uses Diesel.
AlgaeOilAnother source, and quite amazing source, for Bio Fuels, is Algae. Algae Oil can be grown in any water source and can be a great source of base materials for both Ethanol and Bio Diesel production. Algae production in the U.S. is practically non-existent. Algae has a great potential as a source of raw material. The problems concerning food supply associated with producing Ethanol doesn't matter for Algae. Investment in this source should be perused as the pay-off will be immense.
We are now facing a Global Fuel crisis. Rising fuel prices have the potential to impact global society and security in a very negative way. We must now seek an interim solution to this potentially devastating problem until Hydrogen is perfected as a source of energy. Failure to do this could doom future generations to hardship and misery. The time is now to act.

Solar Energy

Solar energy is the radiant light and heat from the Sun that has been harnessed by humans since ancient times using a range of ever-evolving technologies. Solar radiation along with secondary solar resources such as wind and wave power, hydroelectricity and biomass account for most of the available renewable energy on Earth. Only a minuscule fraction of the available solar energy is used.
Solar power provides electrical generation by means of heat engines or photovoltaics. Once converted, its uses are limited only by human ingenuity. A partial list of solar applications includes space heating and cooling through solar architecture, potable water via distillation and disinfection, daylighting, hot water, thermal energy for cooking, and high temperature process heat for industrial purposes.
Solar technologies are broadly characterized as either passive solar or active solar depending on the way they capture, convert and distribute sunlight. Active solar techniques include the use of photovoltaic panels and solar thermal collectors (with electrical or mechanical equipment) to convert sunlight into useful outputs. Passive solar techniques include orienting a building to the Sun, selecting materials with favorable thermal mass or light dispersing properties, and designing spaces that naturally circulate air.
