There are many new techniques of energy available. Worldwide, thousands of researchers working to develop new ways, designed to promote environmentally chris brown mtv awards friendly and economical driving and producing. Completely new sources tapped.
The topic is "hot" in the current credit and environmental crisis. Many come together here, there is need to change things given the threat to the environment. The "green revolution" is now also seen as the solution to the economic crisis. What does this revolution mean exactly?
With this article I would first like to give an overview and state of affairs in which work on new techniques. What's alternatives available for reducing CO 2 emissions and the burning of fossil fuels? And what is there to expect?
We will consider both new car engines, as well as new techniques of electricity. Of dissenters is often true innovation. Vested interests tend to reject chris brown mtv awards these scholars and their ideas.
(The Cadillac WTF with his Thorium is not an option) Part I: Clean engines for the car What are the alternatives to conventional petrol or diesel driving car, with its depletion of fossil fuels and high CO 2 emissions? Biofuels First, there is now increasingly applied this new biodegradable material available for the car. Biofuels chris brown mtv awards are always of organic origin. chris brown mtv awards They are extracted from plant or animal material (biomass), chris brown mtv awards and may be liquid or gaseous. chris brown mtv awards There are various types.
Examples are bioethanol (sugar beet) for petrol cars and biodiesel (rapeseed oil) for diesel cars. Through the use of biofuels in cars greenhouse gas emissions in traffic (still accounted chris brown mtv awards for 20% of total CO2 emissions worldwide) reduced, but they do not disappear by this application.
The European Biofuels Directive requires Member States to endeavor to use biofuels in road transport. So there should installations for bio-diesel that will eventually provide about 5% of the national fuel needs. In Brazil, everybody drives on a blend of gasoline with 30 to 100 percent alcohol. Also in US bioethanol is popular.
The most common form is that ethanol in the form of ETBE (ethyltertiobutylether) is blended chris brown mtv awards into gasoline. It depends on the type of biofuel or off the car engine needs to be adjusted. Without modification of the engine is to add up to 20 percent biodiesel to fossil fuel. Higher mixing chris brown mtv awards rates require adjustments of the engine. Several manufacturers, including Ford, meanwhile produce so-called flexi-fuel cars. These special cars can run on regular gasoline, but also in mixtures with a higher percentage of ethanol (to 85 percent).
The traditional biofuels such as biodiesel from rapeseed oil or sunflower oil and alcohol from sugar beet or corn, also called first-generation biofuels. They provide a CO2 reduction of up to 50 percent. The further development of biofuels could lead to biofuels with a CO2 reduction chris brown mtv awards of around chris brown mtv awards 90 percent. The techniques to make these biofuels chris brown mtv awards are still under development. It's expected that second-generation biofuels only after 2010 on the market. The question is whether they are still needed. When calculating the environmental impact of the government is based on the principle of Well to Wheel (WTW). That means that not only calculates chris brown mtv awards the environmental impact of the fuel itself, but look at the entire process; of the production of the fuel up to and including use. This is necessary for an accurate comparison between biofuels and fossil fuels and between different biofuels themselves. I have no data for this comparison.
There are further chris brown mtv awards advantages chris brown mtv awards to be achieved by growing a number of agricultural crops which can be made suitable as a biofuel. It is clear that the frequently used argument that biofuels are carbon neutral
