We all accept that any home built before 1980 probably consumes energy rather than produces. And we know that most buildings today aren’t much better. Some dabble in industry-tested, user-approved microcosms of water conservation and energy production, and even fewer have thrown away the sound bites of “first cost” and “investment return” and have dove head first into responsible yet expensive net zero homes. Interestingly, The Center for Green Buildings and Cities at Harvard is exploring a strategy that may end up making a huge difference in the average home owner’s ability to achieve energy and water independence. They are currently experimenting with retrofitting a pre-1940’s home to attain net zero. The measures for success will be varied and at this point will still act as a testing grounds for possibilities.
Many of us turn a few knobs and, miraculously, hot water comes out without much thought other than our energy and water bills. However, the water that ends up in the drain retains a certain about of embodied energy that is capable of being recovered. This water is now technically graywater, but you’ve paid valuable money for the energy used to raise its temperature. It makes sense to recapture this energy and there are a few great products that can help with this.
Heat recovery is nothing new, however it is becoming more main stream and affordable than ever before. If you’re looking to cut a few bucks out of your energy bill while looking for a relatively easy way to help make a bigger impact on your regional energy footprint, then a small addition to your water circulation lines may be the answer.
What if everyone could make 1 simple change in their personal habits that would, as a whole, benefit a larger population? First, we instinctively ask ourselves the question (no matter how large our green flag may be): what do I have to give up to make this happen? And if ultimately we can manage the risk, we may accept the proposition. This is the challenge for today’s green energy suppliers. In order to make it convenient for a large group of people, they need to make it competitive with larger corporations. What if you were told it would only end up costing you between $3-5 a month extra to have your electricity provided by 100% renewable energy? Cory, a representative of Green Mountain Energy, offered this option to us this weekend.
