Usually we speak of the benefits of interconnecting energy grids so that
everyone will enjoy the use of electricity. The grid provides the "freeway
for electrons" from generators to customers, and these transmission lines
frequently cross time zones and political boundaries. This in turn allows
for the tapping of renewable energy resources that are often in remote
The Energy Grid can also deliver
the electrical energy to transition the automotive industry from gasoline
engines to electric or fuel cell propulsion systems. The present-day internal
combustion engine is only 5% efficient and causes about 1/3 of the global
carbon dioxide emissions. Our cars are the primary reason that the world
economy is addicted to petroleum.
How can the Energy Grid provide
both propulsion and solve pollution? First, any pure electric vehicle
needs to be charged, and this is usually done overnight with cheaper base-load
power. Then, as fuel cells require hydrogen, the Energy Grid can provide
the electricity to electrolyze water (breaking apart H20). When this hydrogen
is burned or used in fuel cells, the by-product is clean, non-polluting
One way to change the world is by your choice of transportation. The
next time you purchase a car, please consider an electric, hybrid (gas/electric)
or fuel cell vehicle. The enclosed article
from Forbes magazine indicates that industry is getting the message.
The choices we make today influence what automakers build in the future.
