When it comes to going green, sometimes it is far easier and less costly to recover and recycle wasted energy than it is to pay for solar, wind or other systems to produce new energy. Either way, when you are seeking a green, renewable energy source,  the economics are a main consideration. This short article is to call your attention to an often ignored technology call waste heat recovery. Click here for more information on waste heat recovery economics.

In brief:

Solar photovoltaics usually have a payback of 10-13 years depending on tax credits and local electric costs.

Solar water heating usually has a payback of 5-8 years depending on tax credits and local electric costs.
.
Heat recovery water heating has a payback of between 1-3 years depending on electric costs, and no tax credit are needed (although they are available).
