HOW MANY JOULES OF SOLAR ENERGY FALL ON YOUR BACK AS YOU WORK ON YOUR TAN FOR 0.70H?
Sep 7th
Question by ginger_jj:
How many joules of solar energy fall on your back as you work on your tan for 0.70h?
The intensity of electromagnetic waves from the sun is 1.4 kW/m^2 just above the earth’s atmosphere. Eighty percent of this reaches the surface at noon on a clear summer day.
Suppose you model your back as a 27cm & 51cm rectangle.
How many joules of solar energy fall on your back as you work on your tan for 0.70h?

DOES SETTING BACK THE THERMOSTAT IN THE WINTER REALLY SAVE ENERGY?
Aug 22nd
Question by JoeSalsa:
Does Setting Back the Thermostat in the Winter Really Save Energy?
With winter coming up soon, here in the midwest, I am going to ask the question: Does Setting Back the Thermostat in the Winter Really Save Energy?
According to the DOE and EnergyStar, it does. But I, and others, disagree to a point. That point being, “doesn’t it take MORE energy to REWARM the home back to the COMFORT TEMP when you are home?” So in other words, does it take more energy to bring the temperature from 62 to 68, for example, rather than maintaining the temperature at 68 the entire time when the home is vacant?
I need solid proof energy is saved with the EnergyStar compliant thermostats, not just what the websites say. If anyone has any experience or tests, I would like to hear what they have to say. Thanks!
Good answers so far. But my question, originally, is in reference to the SET-BACK type thermostats that automatically reduce the temperature when away, and bring it back up when you come home. In the summer, yes, it is ideal to SET AND LEAVE the temperature at one setting, but should I (or we) do the same for the winter? Does the SET BACK method REALLY work?

Q&A: DO YOU SAVE ENERGY BY LOWERING YOUR THERMOSTAT WHEN YOU ARE NOT HOME AND THEN RAISING IT WHEN YOU GET BACK?
Aug 14th
Question by calla_flower:
Do you save energy by lowering your thermostat when you are not home and then raising it when you get back?
i have heard different sides to this question. I have heard that you will save money if you lower the thermostat in your home during the day while you are at work, but i have also heard that it doesn’t save money because you use more energy trying to raise your home’s temperature, and you are superior off keeping your thermostat at a consistant temp. for refrence in our situation, i was going to lower the theromstat to about 62 during the day and raise it to 68 when we get back home.
