Guest blog by S. A. Shelley: When it comes to energy matters, as in all matters that affect our health or fiscal wellbeing, we tend to be our own worst enemies. There are two components to the global warming surge:  greenhouse gases, which insulate the planet and prevent heat energy from radiating into space, and heat exhaust generated by human activity. The latter is often overlooked and forgotten by most people but is just as critical a factor in global warming. We wrote a blog a few years back highlighting the thermal inefficiency of internal combustion engines (ICEs) which on aggregate pump out a heck of a lot of waste thermal energy compared to their transport energy use (Throwing Away 3 of every 4 Gallons of Gasoline Bought). This is one area in which electric vehicles (EVs) crush ICEs:  EVs use a much greater proportion of their energy to move people and stuff and emit far, far less waste thermal energy. Point to EVs. But there is a myriad of other personal choices that people can make today, without switching to EVs, that will on aggregate reduce the rate of global warming.
