Here’s another flow diagram, from Lawrence Livermore National Laboratory, showing sources and uses of energy in the US, sent to me by a client. Note how much of our energy comes from fossil fuels – natural gas, coal and petroleum. We are addicted to hydrocarbons, and will be for some time. Recent changes in weather patterns reflect what is becoming more obvious – increased CO2 in the atmosphere is warming our planet. But how are we going to stop driving our cars, running our air conditioners, powering our computers? The problem with fossil fuels is that they are too efficient a source of energy.

And here’s a diagram given me by my niece, who is studying biology. I can’t tell you anything about it except that it reflects the inner workings of a human cell.  Things have certainly changed since I studied biology. Note the reference to “Energy” on the right side of the diagram, coming from glucose – sugar.

I ran across this website from the Yale Program on Climate Change Communication, an interactive map that allows one to view different perspectives about global warming across the country. Fascinating to play with. Remarkably, for instance, a large majority of the population in the Rio Grande Valley and far West Texas believe that global warming is happening and a majority there believe it is caused mostly by human activities. Likewise in most of New Mexico and Arizona.  While much of the country’s opinions about global warming does appear to be split along ideological and urban/rural lines, that is not necessarily the case. The data, from 2016, shows that 53% of the country believes that global warming is caused mostly by human activities. 58% of the population is “worried about global warming.” 82% of those polled support funding research into renewable energy sources, and 75% think CO2 should be regulated as a pollutant.
