He is also comparing apples to oranges. The savings of 18 million is dependent on how many people participate in energy star. If, say, only one person bought an ES appliance, then the cost savings would be very small, but what would that have to do with the cost of converting a house? A more realistic way of doing this is to compare the lifetime savings for efficiency. Ransom complains about light bulbs so let’s look at the cost of a LED bulb to his incandescent. If you look at the entire liftime cost, manufacturing and use, a LED bulb will use 280 kWh over its 25,000 hour lifetime. It would require 1,500 kilowatt-hours for the standard incandescent bulbs. Of course, that doesn’t fit into Ransom’s story so let’s ignore the numbers.

It seems you DID ignore the numbers.

What did the actual COST (in dollars) of LED vs incandescent over that 25,000 come to?
Your "realistic" only shows that the LED used fewer kWh - not that it was less expensive vs incandescent. If you want to convert someone - show them that they actually stand to gain: especially in their wallet.

And what about the cost of purchase and installation of the new unit? That offsets most or all of the energy savings for the next 25 years.

The same argument holds for AC. You can easily compare the payback period for using a more energy efficient AC. If your AC is old (over 15 years) installing a more efficient unit could save you up to 30% in electricity.

You can do the math.

Light bulbs use a tiny fraction of the energy in a home. My electric bill more than doubles in the summer compared to winter, even though there are more hours of daylight, and therefore less need for electric lighting. The difference? Air conditioning. I live in Florida. The energy saved by twisty bulbs is insignificant, but the risk of toxic mercury vapor if one breaks is significant. And when millions of them end up in landfills, we'll have a significant environmental crisis on our hands.

I'm proposing a bold conservation program to involve every state, county, and city and every average American in our energy battle. This effort will permit you to build conservation into your homes and your lives at a cost you can afford. I ask Congress to give me authority for mandatory conservation and for standby gasoline rationing. To further conserve energy, I'm proposing tonight an extra ten billion dollars over the next decade to strengthen our public transportation systems. And I'm asking you for your good and for your nation's security to take no unnecessary trips, to use carpools or public...
