Is Biodiesel the cure to decrease pollution in reality?

Question

Biodesel reqiures land to be cultivate, that means it will occupy the area of agricultural farms which is not possible, since we need more food to feed our growing population. so the other option is to clear forest area to cultivate these plants, it is not wise to go for biodiesel at the cost of forest area. also, the number of vehicle is increasing day by day that means the emmission of pollutant will increase. it is better to go for renewable source of energy than the biodiesel.

Answer 1

No, its not the solution. First things first.

Growing crops to convert to fuel ends up competing with crops grown to be used as food. The end result is that the price of food goes through the roof because farmers are making more from growing fuel crops. That's not ever going to be an acceptable situation.

The answer is hydrogen. Hydrogen can be used in existing internal combustion engines. You simply have to change the timing of the engine. Most gasoline and diesel engine ignite the fuel well before the stroke of the engine reaches top dead center. The result is that most of the power generated is lost due to simple counter forces applied to the crankshaft of the vehicle. The end result is that you get about a 25% eefficiency from those engines.

Now, change the timing and add a hydrogen fuel supply. Hydrogen burns much faster than gas or diesel and the timing of the engine has to change to take that into account. You ignite the hydrogen after the engine passes top dead center, you gain back all the power that you lost to counter forces and the efficiency of the engine goes up above 50%.

This doesnt even take into account the fact that hydrogen is the most abundant element in the universe. Setup a solar power plant and use its power output to make nothing but hydrogen. Bang, no continuing costs and you have paid for the plant within a couple of years. You can build the plant in the middle of the desert so you arent fighting for crop lands. You help clean up the environment and the price of food goes down because there is more of it available.

Answer 2

Yes.Bio diesel can decrese pollution.Bio Diesel is a substitute for, or an additive to, diesel fuel that is derived from the oils and fats of plants, like Sunflower, Canola or Jatropha.

It is an alternative fuel that can be used in diesel engines and provides power similar to conventional diesel fuel.

Bio Diesel is arenewable domestically produced liquid fuel that can help reduce the countries dependence on foreign oil imports.

Recent environmental and economic concerns (Kyoto Protocol) have prompted resurgence in the use of biodiesel throughout the world. In 1991, the European Community, (EC) Proposed a 90% tax reduction for the use of biofuels, including biodiesel.

Today, 21 countries worldwide, produce Biodiesel.

The Advantages of Bio Diesel

Bio Diesel is the most valuable form of renewable energy that can be used directly in any existing, unmodified diesel engine.

Energy Independence: Considering that oil priced at $60 per barrel has had a disproportionate impact on the poorest countries, 38 of which are net importers and 25 of Which import all of their oil; the question of trying to achieve greater energy independence one day through the development of biofuels has become one of ‘when’ rather than ‘if,’ and, now on a near daily basis, a biofuels programme is being launched somewhere in the developing world.

Smaller Trade Deficit: Rather than importing other countries’ ancient natural resources, we could be using our own living resources to power our development and enhance our economies. Instead of looking to the Mideast for oil, the world could look to the tropics for biofuels. producing more biofuels will save foreign exchange and reduce energy expenditures and allow developing countries to put more of their resources into health, education and other services for their neediest citizens.

Economic Growth: Biofuels create new markets for agricultural products and stimulate rural development because biofuels are generated from crops; they hold enormous potential for farmers. In the near future—especially for the two-thirds of the people in the developing world who derive their incomes from agriculture.

Today, many of these farmers are too small to compete in the global market, especially with the playing field tilted against them through trade distorting agricultural subsidies. They are mostly subsistence farmers who, in a good year, produce enough to feed their families, and in a bad year, grow even poorer or starve. But biofuels have enormous potential to change this situation for the better.

At the community level, farmers that produce dedicated energy crops can grow their incomes and grow their own supply of affordable and reliable energy.

At the national level, producing more biofuels will generate new industries, new technologies, new jobs and new markets.

Cleaner Air: Biofuels burn more cleanly than gasoline and diesel. Using biofuels means producing fewer emissions of carbon monoxide, particulates, and toxic chemicals that cause smog, aggravate respiratory and heart disease, and contribute to thousands of premature deaths each year.

Less Global Warming: Biofuels contain carbon that was taken out of the atmosphere by plants and trees as they grew. The Fossil fuels are adding huge amounts of stored carbon dioxide (CO2) to the atmosphere, where it traps the Earth's heat like a heavy blanket and causes the world to warm. Studies show that biodiesel reduces CO2 emissions to a considerable extent and in some cases all most nearly to zero

Answer 3

Bio-diesel is made form waste vegetable oil ie. the one you cant use or if special crops are grown those are on arid land, also intercropping is done to get some other edible products too.

So actually bio-diesel cultivations can put wastelands to use and reduce pollution and actually help use part of those wastelands for food growth.

Answer 4

Think about it! The whole bio-fuel idea is BS.  It took many millions of years for the earth to produce the oil we have been burning in our cars and power plants.  We will have gone through all of it in less than 300 years! So if you covered all of the earth with corn or soybeans or whatever, you couldn't grow enough to supply the USA for more than a few days let alone the world.  The bio-fuel issue is a band-aid that someone is going to get wealthy on and politicians are taking credit for. Meanwhile it distracts us from looking for completely new  methods of making power and transporting people.  It's time for us to realize that internal combustion engines need to go and for new technologies to emerge. Solar, wind, nuclear & fuel cells, are all need to be further developed and used in conjunction with each other along with other technologies that someone, somewhere is doodling on a napkin. We need to be cautious that the cost of bringing some of these technologies to market outweigh the benefits.

Some, like bio-fuel, take more energy to produce than they'll save.

Think about it!

Answer 5

I understand that there would need to be room to cultivate the plants but we already use so much vegetable oil that it would almost be self sustaining.  Right now we use used deep fryer oil and turn that into biodiesel also.  But i don't understand your question about  " is it better to go for renewable source of energy than the biodiesel."  Biodiesel is a renewable source of energy and does not add/contribute to the rising Carbon Dioxide in the atmosphere so....
