Alternative Fuel Sources for Automobiles

Thursday, July 24th, 2008

When it comes to powering our automobiles, there are actually many other alternative fuel sources available rather than gasoline. Technology has come a long way since Henry Ford first developed ways to process oil to make gasoline so it could power his new combustion engine for cars. If you own an automobile of any type, you may want to seriously explore alternative fuel sources – and for many reason!

First, burning fossil fuels – like gasoline – damages the environment. The emissions that are released into the air by burning oil-based products – like gasoline and coal – damage the air and the ozone as well. Using an alternative fuel source to power your automobile helps to reduce harmful emissions. In fact, many alternative fuels – such as fuel cells and electricity – release no emissions at all. So when you use alternative fuel sources for your automobile, you are helping the environment in a big way.

Eighty-five percent of all harmful carbon dioxide that is released into the air comes from the burning of gasoline from car engines. The carbon dioxide that is released into the air damages the ozone and contributes significantly to global warming. When we can reduce that carbon dioxide emission by using alternative fuel sources for our automobiles, we can make a huge difference in the world – not just in our own little part of it!

It’s a truth that we are dependent on foreign oil that we use to produce gasoline. Although the United States does have a certain amount of oil that we can use, the fact is that we can’t produce enough to meet the needs of the people. As alternative fuel sources are being discovered and developed, it’s being proven that using these types of fuels in our automobiles make us a self-sufficient nation.

Gas prices are high – there’s no doubt about that! One of the reasons is that we need to burn fossil fuels to power our automobiles as they are built right now – at least most of them! But when we start to use alternative fuel sources for our automobiles, we are drawing on resources that are right here in the United States. And those resources are renewable – like propane, ethanol, and even electricity!

The fact is that using alternative fuel sources to power automobiles is a good choice all-around. Not only are we reducing our dependence on foreign oil, but we are helping the environment as well. Something as serious as helping improve the world we live in should be taken seriously. So explore alternative fuel sources for your own automobile. We’re willing to bet that you’ll find out it’s a good choice no matter which way you look at it!

How Hydrogen Fuel Cells Effect The Environment

Monday, July 14th, 2008

There’s no doubt that the development of hydrogen fuel cells as an alternative fuel is good for the environment, but how does that work? It’s easy to say that we should use hydrogen fuel cell technology to save our environment and prevent global warming. Finding facts about it and embracing those facts can be two very different things.

First, let’s consider the fact that hydrogen fuel cells are good for the environment because they are the cleanest burning fuels ever developed. Hydrogen is taken out of water and then put into fuel cells as a gas that can power a vehicle. The only emission that comes out of a fuel cell powered vehicle is water vapor. It’s like having a humidifier for the whole world!

There are, however, some drawbacks that are associated with hydrogen fuel cells and the environment. A completely efficient system of producing, storing and transporting hydrogen should, in principle, lead to no unwanted emissions of the gas.

But the researchers point out that such a system would be expensive, and that in reality around 10-20% of the hydrogen would escape into the atmosphere. They say that if hydrogen fuel cells replaced all of today’s oil and gas-based combustion technologies, such losses would double or even triple the total hydrogen deposited into the atmosphere at the Earth’s surface.

Other researchers say that the hydrogen would be oxidized when it reaches the stratosphere, which would cool the stratosphere and create more clouds. This would delay the break up of the polar vortex at the north and south poles, making the holes in the ozone layer larger and longer lasting. They estimate that the extra hydrogen will lead to a 5-8% rise in ozone depletion at the North Pole and between 3 and 7% at the South Pole.

The exact scale of this additional ozone depletion, however, depends on a number of unknown quantities. In addition to uncertainty over the extent of hydrogen emissions in the future, little is understood about how soil absorbs hydrogen from the atmosphere. The researchers say it is conceivable that this process could compensate for all new anthropogenic emissions.

The truth is, however, that using hydrogen fuel cells as an alternative fuel is actually – in the long run – good for the environment. When the only emission that comes from hydrogen fuel cells is water vapor, you are talking about a huge advantage over the toxic elements that are released into the air with gasoline burning cars.

The bottom line is that hydrogen fuel cells have a positive effect on the environment. There are many more advantages than disadvantages and hydrogen as an alternative fuel has the most promise over any other alternative fuel.
