The Germans have found a new way to solve a classic greenhouse gas logic puzzle while keeping their auto assembly lines running. The puzzle: What’s the cheapest way to increase electricity generation while reducing carbon emissions, bearing in mind that installing more wind and solar will require investing $2 trillion in new transmission lines and a single 1 Gigawatt nuclear power plant now runs about $17 billion? Two additional facts: Generating electricity accounts for 41 percent of US greenhouse gas emissions, and two-thirds of those emissions are the result of energy being lost as heat, i.e. wasted. The German Answer: Put thousands of VW workers on the assembly line to make home-sized natural gas furnace/hot water heater/generators. These generators, based on a natural gas engine already used in the Golf, are 92 percent efficient (because they can use the waste heat for heating water or homes) and can either produce electricity for home use or put it out on the grid. In other words, they’re removing much of the second fact (waste), and also removing the need to build many more transmission lines. And, if the company Lichtblick is to be believed, they’ll be creating the generation […]
