When comparing old diesels to old coal power plants the power plants win by being more efficient but both belch out a lot of pollution. They also have the advantage of burning coal, a fuel which is available in abundance and does not need as much processing as crude oil does to be used in diesel engines.
When comparing old diesels to modern coal power plants this is true at an even higher level since those modern power plants filter out fly ash and are more efficient.
When comparing modern diesels to old coal-fired power plants the diesels win by being less polluting and possibly on terms of efficiency.
Modern diesels versus modern coal power plants goes to the power plants again since these win on terms of efficiency - especially when using combined heat & power - over the diesels.
- erosenbe0 5y agoI have found measuring in typical American neighborhoods that PM2.5 is raised the most when people burn wood for recreation or heat in the evening. It is much higher in the evening with a few neighborhood fire pits than during rush hour with a few diesel vehicles around. This is also when residents have asthma symptoms too. To be fair they are more likely to be home. So it is not cut and dry but if possible I would love to get rid of vehicle emissions as some particulate is too fine to measure.
- stephen999 5y agoSo what? You can try and clean up both. Particulate is not the only pollutant either. NOx and ozone are also emitted from diesel cars.
- erosenbe0 5y agoAgree, just saying vehicle emissions are part of the picture and more work needs to be done on air quality.
