## Two pronged attack Energy Efficiency and Conservation

The total energy efficiency of the United States is less than 50% and the total amount of energy produced by oil and coal together is almost 75%.

Now let’s pretend we would like to put less carbon into the atmosphere and as a given oil and coal happen to be the sources that put most of the carbon into the air. If we could increase the overall efficiency by a quarter, we could use a third less carbon fuel.

So I guess the question is what are the obstacles to not wasting more than half of the energy we produce? Are the costs associated with such an endeavor so high that it is really not worth the investment?

Doing some research on fuels and their various efficiencies,  wood can burned generating heat energy at above 90% efficiency in the right kind of fireplace.  The technology for burning wood has been developed since the beginning of mankind but I still think we could still waste less energy with other fuels as well.
