When many people think about a “green” house, they picture a small hut made out of mud where people sit on dirt floors, desperately trying to not use any energy. But by doing some careful planning and designing, and paying about 10% more on construction costs, this family’s home uses 50% less water and a whopping 90% less electricity than a similar-sized “normal” home.Some of the things they did are:
capturing rainwater and snow melt to flush toilets or water the lawn
“recycling” heat from hot water to help the water heater
If you’re thinking about building a home in the near future, and you’d like to cut the water bill in half and the electricity bill by 90%, then here’s how. I plan on one day following some of the tips in the video to make my house as cheap (and eco-friendly) as possible, while maintaining that normal home look.
Earthships are houses made with discarded tires, bottles, and cans, put together with lots of dirt. Many of them are self-sufficient, creating their own energy, and capturing their own rain-water. Since they’re made from reused/free materials, and supply their own electricity, heating, and water, they help conserve natural resources while also saving chunks of money. I’m down for anything that helps the environment AND saves me some dinero.
But I digress. I now present to you, courtesy of Earthship.net, “Earthships 101″.
Amory Lovins, who won a MacArthur Genius grant back in 1993 (and an Eco-Hero Award just right now), has been living in a house he built since 1983. It looks like a very nice and comfy house, especially when you consider that, despite living 7,000 feet up in the Rocky Mountains (where it gets pretty dang cold), he pays $0 a year on his heating. Not only that, but his house actually generates more electricity than he needs — so he sells the surplus energy to the power company for some extra cash. Here are three ways to cut your electric bill like crazy.
His secret (one of them) is that he designed his house to be very well insulated. His walls are 16 inches thick, and his large super-insulated windows (made with special glass that insulates as well as 14 normal panes of glass) mean that his house can retain heat quite well.
Passive and Active Solar Heating
Lovins’ house is heated in two main ways: both from sun-rays passing through his many windows, or by means of Amory’s solar panels, which supply his house with more energy than it even uses.
Energy-Efficient Appliances
Much of Lovins’ house is naturally lit by the sun. Besides that, motion-detector lights and energy-efficient bulbs help to cut down on electricity use. His fridge is thickly-insulated, which reduces its energy consumption by quite a lot. His dryer is solar powered, and looks like it uses no electricity at all (watch the video to see how).
Amory Lovins’ home took some extra thought to design and build. It also cost a little bit extra ($6,000). But by cutting his power bill to zero, the extra planning and money spent were easily worth it. If more and more contractors start building this way, you could kiss our “oil prices” and “energy crisis” problems good-bye.
Roads and parking lots. They are everywhere in today’s busy, dog-eat-dog, modern world. They sit there all day, selfishly absorbing the sun’s rays, then squandering all that heat at night by simply releasing it into the night air. Welp, a Dutch company named Ooms Avenhorn Holding BV is now working on ways to take that solar energy and use it to heat homes and offices.
Ooms has already implemented this technology in several places around the Netherlands; solar energy collected from nearby roads and parking lots helps heat an industrial park of 160,000 square feet in Hoorn, a 70-unit apartment building in Avenhorn, and an air force base hangar.
This is a great idea; even on cloudy days, this system of getting heat from roads is effective. Let’s hope that America can build off of this Dutch technology and start using our numerous roads and parking lots to heat our buildings. Just think about how much of our land in cities is taken up by roads and parking lots. Imagine if we were using that captured solar energy to heat our buildings. We could cut our power usage in a huge way, while not sacrificing anything in the way of personal comfort.
A good article about getting energy from asphalt can be found right about here. Thanks to my pop for letting me know about this.
