<p>[quote user="Norm48327"]</p> <p>[quote user="Bucyrus"]</p> <p>[quote user="Norm48327"]We have plenty of fossil fuel and the technology to burn it cleanly. Why not use it?[/quote]</p> <p><span style="font-family:verdana,geneva;font-size:small;">Burning it "cleanly" would be fine if means burning it without emitting CO2. Can we do that?</span></p> <div style="clear:both;">[/quote]Trees and other plants need CO2 ro grow.[/quote]</div> <div style="clear:both;"> </div> <div style="clear:both;"><span style="font-family:verdana,geneva;font-size:small;">That is true, but burning fossil fuels releases CO2 that has been historically locked up or sequestered on a permanent basis. So adding that old CO2 increases the total free CO2 beyond what the normal cycle of plants consume and animals emit. </span></div> <div style="clear:both;"> </div> <div style="clear:both;"><span style="font-family:verdana,geneva;font-size:small;">Therefore, to make coal burning acceptable, the CO2 must be captured after combustion and locked up somewhere and somehow, for the rest of time. </span></div>
