Question by Fynnagin F: what colors should tubes be for a solar water heating system?
Solar energy can be used to heat water for a pool by running water through a series of pipes or tubes. What colour should the pipes be? What other features should this system have to improve its efficiency?
Best answer:
Answer by fill YerbootsMatt black unless you are in a seasonally very sunny area. The black absorbs heat very well, so potentially it could get hot enough to boil the water if you are in an occasionally very hot climate. Some areas use pale colours [...]

Question by Bill O: Alternative energy vs. drilling for more oil?
Is this a true statement?
If the US does more domestic oil drilling, the oil companies get richer.
If the US develops alternative energy (wind, solar, etc), this would create a whole new industry and create more new jobs.
Best answer:
Answer by Zach Twhy don’t we do both? drill for oil for short-term relief, while developing alternative energy for the long term.
the two aren’t mutually hostile situations, they can work with each other.

Question by jay: The Sanchez household is about to install solar panels to reduce the cost of heating their house. ?
In order to know how much the solar panels help, they record their consumption of natural gas before the panels are installed. Gas consumption is higher in cold weather, so the relationship between outside temperature and gas consumption is important. Here are data for 12 consecutive months:
Degree days193300081127463834
