Green transporation mediums

Description:

Hybrid fuel / electric cars have been around for a few years now. They are more expensive to purchase and maintain when compared to the standard petrol engine vehicles. Withing the last 5 years,however, we have seen a move towards more enviromentally friendly solutions for our transporation needs. These include hydrogen fuel cells, solar energy, biofuels and more traditionally bicycles.

==Hydrogen fuel cells==

===Ballard Power systems===
Manufactures and researches fuel cell batteries and technology. Has a portfolio of products ranging from UPS (uninterupted power supply) modules, industrial motors to fuel cell powered automobiles and buses.

A fuel cell converts the chemicals hydrogen and oxygen into water, and in the process it produces electricity. The proton exchange membrane fuel cell (PEMFC) is one of the most promising technologies. This is the type of fuel cell that will end up powering cars, buses and maybe even our homes.

==Kyoto Protocol==

The Kyoto Protocol is an agreement under which industrialized countries will reduce their collective emissions of greenhouse gases by 5.2% compared to the year 1990 (but note that, compared to the emissions levels that would be expected by 2010 without the Protocol, this target represents a 29% cut). The goal is to lower overall emissions from six greenhouse gases - carbon dioxide, methane, nitrous oxide, sulfur hexafluoride, HFCs, and PFCs - calculated as an average over the five-year period of 2008-12. National targets range from 8% reductions for the European Union and some others to 7% for the US, 6% for Japan, 0% for Russia, and permitted increases of 8% for Australia and 10% for Iceland.
