, formerly known as the Rocky Mountain Institute. Their premise is that we waste about two-thirds of all the energy in the coal, oil, and methane we extract from the Earth every year. We don’t realize this as we motor along in our new Belchfire 5000 or turn up the thermostat when the temperature drops in December, because it is second nature to us. It’s what we do and everybody we know does the same thing, so it must be OK, right? Wrong, octane-breath.
Today’s energy system is incredibly inefficient, RMI points out. We waste almost 400 exajoules of all the energy going into our energy system. A joule is a unit of energy equal to the work done when a force of one newton acts through a distance of one meter. It is also a unit of electrical energy equal to the work done when a current of one ampere is passed through a resistance of one ohm for one second. Pretty small stuff, in other words. An exajoule, on the other hand isstuff.
It takes energy to make energy. The three key drivers of energy waste in production processes are extraction , fuel processing losses , and power generation losses . Fossil fuel technology not only has poor energy efficiency, it also produces a lot of other waste byproducts. Burning fossil fuels emits 35 of the total 37 gigatons of CO2 emitted each year and is responsible for another 3 Gt equivalent in methane emissions. Fine particulate matter — particles smaller than 2.5 microns in size — are responsible for over 5 million deaths per year and are directly attributable to burning fossil fuels., RMI says.
