Once upon a time we hunted and gathered our food; we made our fire from rubbing two sticks together; and we pretty much relied on the sun, rain and nature to provide all that we needed to sustain life. Fast forward to the 21st century and we find that much of our existence—from food production to transportation and housing—is dependent on technology. And most technology relies on oil and electricity. When any region connected to our national grid goes down, modern life as we know it and all of its “convenience” is disrupted.
Brownouts and blackouts are becoming problematic and more common as more people plug in, especially during “peak” times (mornings and evenings). Transmission losses can be as much as 80 percent, between the energy generation plant and power reaching our buildings. Our tax dollars pay for these losses with subsidies.
