How Much Will Switching Light Bulbs Save You?

Thomas Edison, the man largely credited for inventing the modern incandescent light bulb as we know it, once said that “we will make electricity so cheap that only the rich will burn candles”. While I appreciate the philanthropic nature of his comment, something tells me he never would have predicted just how much it costs to power the light bulbs that illuminate our homes more than a century later. According to the US Energy Information Administration the national average per kWh is…

Building a Tiny House With Straw Bales

According to Click Green, hay bales can make an affordable, energy efficient, and sustainable tiny house that can keep you and yours safe and warm far off the grid. The bales have 75% more insulating power than a traditional stud wall filled with fiberglass insulation, and are non-combustible because they have little to no oxygen inside. → Related product: Metal hay storage buildings To begin, frame the dwelling as you would a “conventional” tiny house‘s post and beam structure, then fill in…

High-tech Fiberboard Made from Waste Fiber

There’s a new green building material on the market that is light, strong, and flexible, and can be made into just about any shape, including complex molded shapes, without the need for any glues, harmful chemicals, or toxic ingredients. This material, called ECOR, is a high-strength fiberboard made using only water, heat, fiber, and pressure, and takes a low-value product (waste fiber) and turns it into a high-value green building material. At its most basic, ECOR, from Noble Environmental, is…

The Dark Side of Solar Energy: Solar Weaponry

John Perlin’s book, “Let It Shine: The 6000-Year Story of Solar Energy,” tells of a scheming thirteenth century priest/scientist who tries to convince the Pope to start a solar weapons’ race by showing him a treatise written by an early Muslim geometrician regarding solar burning mirrors. Had solar energy lived up to its threat as the ultimate weapon, it might have taken center stage much earlier as the power source of the world. The military today revisits this thirteenth-century vision…

Solar Saga Continues: The Koch Brothers Weren’t the First to Try Stopping Solar

Special thanks to author John Perlin for this solar history contribution about others who long ago tried to end one solar entrepreneur’s life.
