<p>Is there a breakdown of heat produced, when, where and how much over time and the electricity produced? Detroit(?) has a W2E plant which distributes heat as well after steam is used to generate electricity. Apparently, waste to energy plants are closing for a variety of reasons. But what will replace them?</p>

<p>Biodiesel, B100, has a lot of upstream/A to Z CO2; about 45.24% of combustion CO2.</p>
<p>Even if combustion CO2 were not counted "because it is renewable", there still would be a lot of CO2 associated with the biodiesel part of the central plant, which provides 24% of the heating.</p>

<p>Burning wood chips has about 15% of upstream/A to Z CO2.</p>

<p>Burning wood chips has about 15% of upstream/A to Z CO2.</p>
<p>Even if combustion CO2 were not counted "because it is renewable", there still would be a lot of CO2 associated with the wood chip part of the central plant, which provides 76% of the heating.</p>

<p>There will be hundreds of scars on the forest landscape where logging took place to feed wood chips to the new plant.</p>
<p></p>
<p>Some of those scars will be clearcuts, the worst kind of logging, as it kills the forest biomass below the ground, which would have to rebuild itself. That is what happened in the 1800s.</p>
<p></p>
<p>NE forests still have not recovered from that devastation. We mostly see spindly trees that become sickly and do not live long, and a takeover of the forest by acid loving trees, such as white pines.</p>
<p></p>
<p>Taking wood from the forest ultimately will deplete the soil, which was already damaged due to clear cutting in the 1800s and due to acid rain since the 1950s.</p>
<p></p>
<p>There is absolutely nothing about wood burning that is renewable, as various damages are near permanent.</p>

<p>Studied 'green waste' hauled to town dumps for disposal and found quite a bit of it...problem is aggregating it and chipping it--just another approach.</p>
<p></p>
<p>Surprised they didn't consider natural gas as an energy source combines with methane from anaerobic digesters. </p>
<p></p>
<p>Dartmouth was one of the leaders in solar powered car and plane development,so I'm surprised they settled on wood chips and deforestation.</p>
