Obama and Coal

Some blogs have questioned Barack Obama's new bill that would support to some extent the use of liquid coal.

They say this goes against Obama's declared green credentials and his commitment to battle climate change.

Liquid coal is a cleaner alternative to diesel, still the main fuel for heavy transport in the U.S. It might also be a bit cleaner than gasoline. And the coal can be found in the United States so there is much less transportation involved in its use.

Personally, I believe that solar energy is the way to in eventually finding the right "mix" for sustainable energy production. Nearly all of our energy production currently is solar although much wrapped up with carbon through photosynthesis of plant life.

However, solar can never be the sole solution and their definitely will have to stop-gap measures on the way before solar energy obtains worldwide "grid parity," the point where it matches other sources in cost.

One big short-term solution is the use of biofuels, which Obama has routinely promoted. Biofuels are also part of the long-term solution, but only on a limited scale. Too much use of biofuels could threaten rainforests as the world population continues to grow, which would be counterproductive. However these clean fuels offer a quick way of reversing current trends.

Liquid coal can also be part of an interim mix until better technologies are poised to take over. To some extent this takeover is already starting to happen with solar energy. In many locations, solar has reached grid parity. Investment is pouring into the solar energy industry. Technologies are developed that help bring down the cost of refining silicone, the primary "ingredient" in photovoltaic cells. Silicone is the second most abundant element

Obama is a pragmatic politician rather than a purist and liquid coal in his view may represent a way, probably a temporary way, to start achieving energy independence. However, it is clear from his policy statements that it is not a main solution for he doesn't mention coal at all in most of his energy papers and speeches.

Walk for Change

Senator Obama may have some wonderful futuristic ideas however, the rest of us live in the present.

The price of crude oil will soon be trading way over $100 per barrel and the price of gasolines will soar over the $4 per gallon level. What are we to do? Wait 5 years until the first coal oil plants come online? The inflation is eating us up alive.

I am tired of listening to empty campaign promises. If elected, what will Preident Obama do to quickly reduce manufacturing and transportation costs? What kind of fuel will we use in our automobiles and at what price?

If Senator Obama wants my vote he will have to provide straight answers.
