I've learned recently that in addition to buying products that are better for the environment (such as energy saving bulbs and biodegradable cleaning products), there are some things that homeowners can do to reduce the environmental impact of our homes. From a friend, I heard about installing grey water systems (for example using shower drain water to then flush the toilet), and solar-powered water heaters... And now I'm wondering what else is out there?? These seem like relatively simple "tiny remodels" that can make a huge difference on our environmental impact. Can the Celsias community enlighten me as to what else we can do along these lines? Thanks in advance!
