Would covering our roofs with aluminum foil decrease green house warming?

Question by Mr Average Joe: Would covering our roofs with aluminum foil decrease green house warming?
I heard that painting our roofs white would decrease global warming.

How about aluminum foil?

We could cover our entire earth that is “bare” with reflective cheap aluminum foil.

Will that produce a significant drop in global temperature?

Best answer:

Answer by thegeologist
By painting dark surfaces with a more reflective color, solar energy could be radiated back out in to space before it turned into infrared energy (heat). Foil would be more effective than white paint, but the additional costs would probably outweigh any benefits.

The main purpose of the lighter colors would be to keep buildings from absorbing the extra heat and requiring more energy to keep them cool. That reduction in energy consumption would allow for less burning of fossil fuels and thereby reduce the amount of carbon dioxide released.

There won’t be a significant drop in the global temperature right away since the carbon dioxide in the atmosphere has a residence time of several decades to over a century.

One rather fanciful proposal was to put a large foil shade out in space that would cut the amount of sunlight reaching Earth.

Q&A: How do you clean green house fiberglass roof panels?

Question by Karren R: How do you clean green house fiberglass roof panels?
Moved to older house with attached greenhouse. There are 3 fiberglass panels on roof. Have cleaned off most of the black ‘gunk’ but they still show lots of dirt areas. What’s the best way to clean and what’s best to use?

Answer by uk_staffie
Try some AutoGlym Caravan and motorhome cleaner. I have used that on many different fiberglass things, even on my boat. Works really well and seems to remove all the black and green algae.

Answer by billy brite
Buy an old single wide junk mobile home, strip it down to the bare frame, then build your greenhouse on it. To make it 30′ long, you might have to weld some more steel to it.

what are some ways to make your house greener?

Question by : what are some ways to make your house greener?
I am writing a paper on how to make your house greener as in a better place for the earth and save money. What are some sujestions you have. Right now i have three subtitles; saving electricity, saving water, and recycling. What are some good things to put under these.

Best answer:

Answer by †X€NØNN†
saving electricity:
using low consumption light bulbs.
using alternative energy sources to supplement the others , like solar power (can also be used for heating tough), wind power, hydroelectric power etc..

saving water, have a rain water collector (reservoir) and use a water filter/purifier, thus you save water.
we have one of those setups in our house, its simple and works very well.

recycling, well water used in the sink and such can be recycled to use to flush the toilet for example.

also we have a furnace used for heating , used the wood form 2 trees that needed to be chopped down cause they long since died and could have been dangerous.
with that wood we saved about 3500$ of heating, even if the wood is bought then you can still save up (at least here where gas-heating is very expensive)

besides that just don’t waste anything, and use biodegradable materials.

for refference I participated (and still am) in an extensive design of a house ( purely academic I doubt we will ever have it built, whereas i can’t send you the design..
i can give you a few details
for one
it had a beautiful garden with a waterfall was actually a part of the water filtration dispersion and sewage recycling system ( meaning it also watered the plants in the decorative garden and the lower lying vegetable garden)

the waterfall also provided a little energy by using a hydroelectric motor. which mostly powered the outdoor lights
also the house had quite large solar panels on the roof.
a natural water filtration system for the pool, and a water reservoir neatly built into the house,

large windows, and skylights offered natural light throughout the day, and an economic design of the house allowed more areas to be optimally light with just one light.

double layered isolation, and windows that can be simply set to let infrared light kept it warm during winter . and can be made totally opaque for privacy, or set to not allow some gamme of light through to keep the place from warming up in summer

it had an interior well equipped gym, and the machines where actually tied to dynamos to produce electricity when used. ( this is kinda prototyped as of now)
the electricity gained from it is substantial, but since its a pretty erratic source storage and use becomes a headache.
