There&#x27;s still other reasons natural gas is a better fuel, though. Plants come on &amp; offline more quickly, there&#x27;s no need for emissions scrubbers &amp; no truly noxious combustion byproducts. There&#x27;s also no steam output or water consumption, though as there is still waste heat maybe that doesn&#x27;t matter.<p>There&#x27;s also potential to get natural gas plants up to 60-80% efficient, which means still less CO2 production compared to a 30-40% for coal.
