PSDcast – Moving Towards Renewable Energy (and How it Effects Oil)

A petroleum engineer and consultant, Ian Palmer, PhD has worked at Los Alamos, The Department of Energy, BP, and Higgs-Palmer Technologies. He is a contributor at Forbes.com and the author of The Shale Controversy.

As federal mandates and the natural march of technological progress cause the gradual wholesale transition from fossil fuels to renewable energy – and it’s not “if” but “when” – the only questions surround just how rapid those changes will be and how much of a disruption it’ll be to the oil and ga

Saving the Climate with Solar Fuel

By 2030, the retailer Lidl Switzerland will switch from fossil natural gas to liquefied renewable gas to operate its trucks.

Mobility analyses show: Only a small proportion of all vehicles are responsible for the majority of the kilometers driven. We are talking above all about long-distance trucks that transport goods all over Europe. If these continue to be fueled with fossil energy, it will hardly be possible to sufficiently reduce CO
