Today we look a three new papers that reveal renewable energies don’t deliver what their proponents like to have us believe they do, i.e. clean, affordable and reliable energy.
The first paper by Emery et al., 2017, looks at biofuel and found:
Life-cycle non-GHG air pollutant emissions, particularly NOX [nitrous oxides] and PM [particulates], are higher for corn ethanol and other biofuel blends than conventional petroleum fuels.”
Other findings include 1) emissions of volatile organic compounds (VOCs) and carbon monoxide (CO) increase by 9–50% per 100 km traveled for high-ethanol blends from corn grain and combined grain and stover feedstocks, 2) NOX, PM [particulates], and SOX [sulfur dioxides] increase by 71–124% from corn grain and 56–110% from combined grain and stover, relative to conventional gasoline. and 3) The total social costs of ethanol blends are higher than that of gasoline, due in part to higher life-cycle emissions of non-GHG pollutants and higher health and mortality costs per unit.
In Germany many people are apprehensive about putting fuels blended with ethanol or biodiesel into their tanks because it is long known that these fuels are more aggressive with the vehicles fuel burning systems. I never put the stuff in my car.

Another study by Mahapatra and Ratha, 2017, finds
| Paris Climate Accord: Miles to Go
onlinelibrary.wiley.com The vicious effects of climate change are sweeping the planet along with the creation of a level of emissions that would lock in a future of rising sea levels, intense droughts and food shortages, more…
The Paris deal is founded on a voluntary basis without any legally binding caps. The Paris Agreement is a relatively toothless one, which does not bind countries to actual emission limits, and has no mechanisms to impose actions. No sanctions will fall on any country that fails to come up to these intentions. The poor nations want clear promises to increase the aid for them, while the USA and other rich nations favour vaguer wording. Professor James Hansen—credited as being the father of climate change awareness— said that ‘the deal is worthless words’ (Wente, 2015). The final text contains only bland platitudes. There is no necessary connection between the legally binding nature of an international agreement and its effectiveness in producing outcomes (Lake, 2015). The agreement delineates an aim for reducing temperatures to a 2°C above pre-industrial levels, but does not commit. —– Vass, 2017
