When it comes to cooling your house, there are a number of options beyond air conditioning. | Photo courtesy of ©iStockphoto/chrisgramly.
Although your first thought for cooling may be air conditioning, there are many alternatives that provide cooling with less energy use. A combination of proper insulation, energy-efficient windows and doors, daylighting, shading, and ventilation will usually keep homes cool with a minimum of energy use in all but the hottest climates. Although ventilation should be avoided in hot, humid climates, other…

Coal, in contrast, took millions of years to form in the earth, and yet is our culture’s main source of electrical energy. That’s unfortunate, because burning coal and other fossil fuels is what’s driving climate change, also…Continue

The kitchen is illuminated with ten 12W ceiling can lights. The two pendant lights are 3W LEDs. LED equivalents were not yet available for the fluorescent undercounter lights.
This all started in August 2010 when we discovered that a rat had eaten gaping holes in the outlet hose of our dishwasher. When all the damage was counted, we were looking at a complete remodel of our kitchen area, covered in part by our homeowner’s policy.
Eventually this led to a complete energy revamp of our home, and, very pleasingly, a dramatic drop in our electrical bill—from roughly $400 per month on average in 2008 to roughly $60 per month in 2012 (even including the cost of a swimming pool filter pump, which must run five hours per day, 365 days per year).…Continue
