Transportation is another sector that has increased its relative share of primary energy use. This sector has serious concerns as it is a significant source of CO2 emissions and other airborne pollutants, and it is almost totally based on oil as its energy source. An important aspect of future changes in transportation depends on what happens to the available oil resources, production and prices. At present, 95% of all energy for transportation comes from oil.

Addressing global warming, however, is a highly complex and daunting endeavor. Many climate experts have urged the world to stabilize greenhouse gas concentrations in the atmosphere around 450 to 550 parts per million (ppm)—that is, no more than 450 to 550 units of greenhouse gases for every million units of air in the earth’s atmosphere. This approach, experts say, could keep average global temperatures at no more than 3.6° Fahrenheit (2° Celsius) above preindustrial levels, which could avoid some of the worst, irreversible consequences of climate change.

A fuel cell is an electrochemical device that combines hydrogen with oxygen to generate electricity, heat and water to produce. In many ways, the fuel cell is similar to an electrochemical cell. Instead of a regular charge, a continuous supply of oxygen and hydrogen is supplied from outside. Oxygen is produced in the control of air and hydrogen as a fuel made from a pressure instrumentation container. Alternatively, methanol, propane, butane, natural gas supply and diesel are used.

Under both former President Bush and new President Obama, the U.S. government has vowed to reduce reliance on imported oil. The nation is encouraging development of a transportation fleet that uses biofuels, fuel cell vehicles and hybrid electric technologies.
Us Government Program To Reduce Reliance On Imported Oil
To that end, the federal government, in late 2008, put in place new incentives – and extended others – designed to create a strong up-tick in sales of unconventional vehicles. As a result, the U.S. Energy Information Administration anticipates that hybrid cars will grow from 2% of new light-duty vehicles sold in 2007 to 38% by 2030. (more…)

The pace of innovations in batteries has not matched the remarkably fast evolution in the development of portable electronic technology. Batteries are widely regarded as the weak point slowing the rapid innovations in portable technology. Chief among consumer complaints are that batteries do not last long enough and that they do not last as long as the manufacturer claims they will. (more…)
