Like most Americans, I would love to be able to drive without having to fill up with increasingly expensive gas – costly not only to our wallets, but to the environment and to geopolitics. Why not switch to a hybrid vehicle or even better, an electrical vehicle? Wouldn’t an electrical vehicle offer a better, cleaner approach?

I imagine parking my new electrical vehicle in the garage, plugging it in overnight to recharge for a new day, unfettered by gas and oil, sleeping soundly. If only it could be so.

Of course, electricity is generated by a variety of sources, ranging from nuclear, oil, gas and coal. Where does your electricity come from? It depends on where you live. You can use this tool from the Environmental Protection Agency to find out. I tried it using my zip code in New Jersey, and learned that fully 40% of the electricity I use is generated from nuclear power, and 42% from coal {see graph below.} There’s the rub.

The documentary film “The Last Mountain” was debuted recently at the Sundance Film Festival (the trailer can be viewed above) and begins with a startling statement by Robert F. Kennedy, Jr. — the process of mountaintop mining to extract coal can require -

“An explosive power the size of a Hiroshima bomb – once a week.”

Do we need “weekly Hiroshima-sized bombs” to satisfy our appetite for electricity? Here’s an excerpt from a recent film review:

It’s true that watching “The Last Mountain” is partially an exercise in shock and despair. Our systemic dependence on dirty fuels is a deeply entrenched political and practical reality. But Haney’s film, thankfully, is as optimistic as it is intelligent and incisive, envisioning a future in which we can make clean and renewable energy sources readily available to all. Haney’s eloquent documentary transcends the battle being waged in West Virginia. Its realities and truths encompass all of us — not just Americans but people everywhere whose rights, well-being and dignity are being trampled upon by the arrival of predatory corporations.

The focus of this documentary film, Massey Energy Company, presents themselves as “doing the right thing with energy” and as proud environmentalists:

Can both of these perspectives be accurate? Of course not. Could the truth lie somewhere in between?

I think I’ll hold off for now on purchasing that electrical vehicle – or should I buy one now?
