It takes a lot of energy to make gas.. A Bright Idea...part four.

It takes 6 kwh of energy to refine one gallon of gasoline to drive one car 22 miles. 

250 million electric cars (our US total of cars and trucks)  can drive all year without one new kwh of electricity generated.  Read on!

I don’t know about your home, but ours has approximately 150 light bulbs inside and out. Gone are the days when a square room had one bulb in the middle of the room and the outside of the home had one porch light.

So here’s a quick and easy way to fuel your electric car for the next 30 years, I love the dimmable LED bulbs that Home Depot sells.

50 Dimmable LED bulbs at Home Depot = $500

Each LED bulb is comparable to a 50 watt incandescent bulb. (it’s much brighter than a 40 watt bulb)

Each LED bulb saves 41 watts an hour.

Assuming the bulb is illuminated for four hours a day on average, each bulb would save you 164 watts a day, approximately 60 kwh a year.

50 bulbs would save you 3000kwh of electricity a year.

The 3000 kwh you saved by replacing the 50 incandescent light bulbs, will drive a BMW ActiveE 12,000 miles a year for 30 years which is the rated lifetime of the LED bulb.  (46 years or 50,000 hours)

You can drive an electric car 12,0000 miles per year for $16.66 per year of saved electricity. (The $500 in light bulbs divided by 30 years)

In an equivalent gasoline car the cost of gas would be about $2,000 per year or $90,000 (assumes 3% annual increase) for 30 years.

Another interesting electricity factoid is that just four 100 watt light bulbs on 24 hours a day will use more electricity in a year than driving an electric car 12,000 miles a year.
Did I mention that our country exports its weath and is dependent on imported oil?
Did I mention that these LED lightbulbs are made in the USA?

In Summary,

We don’t need to generate a single watt of new electricity in this country to fuel our entire electric vehicle fleet. Simply by using more efficient light bulbs, appliances, and electronic equipment like computers, TV’s and DVR’s in our 114 million households as well as our stores, offices and factories we can save more electricity than the electric cars will use.

It truly is that simple.

It’s your choice,
$16 a year to save the electricity or $2000 for gasoline.
50 light bulbs or 15,000 gallons of gasoline.
