How much coal does it take to power a 100 Watt Light Bulb for 1 year?

Interesting, one average person also emits roughly about 100kw/h in IR range. So, instead of burning 133bulbs we may invite 133 guests, they will heat the 1600sq.f house.
But you need to feed them with something, and it will be more costly....

You are onto something!

And how much heat could those 133 guests produce in bowel gas? Between the heat and entertainment value of it all, its worth a billion dollar govt study...

Bowel gas? I don't want 133 ppl in my house ...

Actually the light is another source of heat , because as it

strikes any surface the heat is liberated.

Think the sunlight , it turns the light to heat whenit hits the

earth.

Tell me how much bit it takes to run a Volt for a week of average commuting. Bet that will calculate out to be real GREEN!

I don't know about the VOLT , but my BOLT EV gets 2.6 miles per KW.

If Gasoline is $2.75 per gallon and my off peak electric is <$0.06 per KW

then the ICE will pay $0.0917 per mile...

Whereas my EV will pay $0.023 per mile....

About 4 times as much for gasoline...

This is in winter and in warmer weather the cost at 4 miles per KW

is about $0.015 per mile so gasoline is 6.11 times more expensive..

Read the question again, that was not what he asked.

It certainly wasn't what he asked.

Lenght of commute ???

5 days a week???

At US Average 40 mile Day = $0.023 X 40 = $0.92 per day

5 x $0.92 = $4.60 per week

Best without more details... Actually very little green notes...

Did you remember to add an ~$10 grand upcharge to the price of the car (after taxpayer subsidized kick-back) and then figure out the cost per day?

If you plan to keep it for 5 years, that's an extra $5.50 per day (before considering the interest on the loan). Call it $7 per day when loan interest is factored in. I can drive about 84 miles a day on gasoline for free for 5 straight years if I'm saving $7 per day vs. buying an electric vehicle.

... and you dont have the low electric rates he has shown in his figures.

BB, look at the thread about European boilers and contribute your knowledge on that subject, which you have, instead of just trolling us all day with fake figures.

Using only the figure refrenced in this thread Barney burns about 1.63tons of coal per year to drive 200 miles a week.

Best I can figure about 135 square feet of solar panels.

1,108,590 chest x-rays if he went nuclear.

12 eagles, 52 hawks, and 3,650 misc. other birds if he went with wind for power.

I like your math!

Some rare bat saved wind towers from being built a couple miles from me. I guess they really get killed if one is near. They live in caves all around here.
