If all Californians used clotheslines, one nuclear power plant could be shut down.

During the Leave-It-to Beaver era of the late 1950s, most homes certainly had a clothesline and probably no one thought much about whether it offended their neighbors. It’s a safe assumption that June Cleaver, the perfect homemaker, would have taken issue with anyone even hinting her clothesline was an eyesore.

Then fast forward a half century to the present where the majority of Americans have abandoned the clothesline in favor of electric or gas dryers and homeowners associations (HOAs) routinely prohibit clotheslines or impose such restrictions as to effectively ban them. One can only guess what June would have said to that, even absent her knowing about the threats from global climate change and the pressing need to reduce America’s dependence on fossil fuels.

Few today will dispute that tossing a load of wet clothes into a clothes dryer is more convenient than pinning up clothes, one by one, and surveys confirm that most people living in communities governed by HOAs have no problem abiding by the restrictions on clotheslines from the standpoint of curb appeal or property values.

However, interest in reducing the oversized energy footprint of Americans – twice that of people living in the European Union – has given rise in a handful of states to so-called “right-to-dry” laws that rein in restrictions HOAs or other entities can impose on residents’ freedom to use clotheslines. California is not among them, however, despite its sunny weather and reputation for environmental progressiveness.

No Such Thing as a Green Lawn

Which consumes more fossil fuels, lawn maintenance with gas-powered tools or lawn watering? For residents of Southern California, the correct answer is watering because of the energy it takes to transport water to the region.

Southern California (SoCal) is a semi-arid desert. Rainfall averages only 15 inches per year, for example, in the Los Angeles area.  Local water sources have fallen far short of meeting the region’s water needs for more than a century.

With 2/3 of the state’s rainfall in Northern California and 2/3 of the water demand in SoCal, the State deals with this imbalance by pumping in half of SoCal’s water supply from sources hundreds of miles away, the Colorado River and the Sacramento-San Joaquin Delta.

The Water-Electricity Relationship

Piping water long distances is costly in terms of electricity, especially water imported from the Delta which has to be pumped uphill 2,000 ft to get over the Tehachapi Mountains.

In a first ever analysis of the energy embedded in bringing potable water to residential faucets and hoses in SoCal, a 2005 Calif Energy Commission analysis calculated 11,111 kWh/MG  (kilowatt hours per million gallons), three times costlier than in Northern California. Most of the electricity is for water transportation, much less for water treatment and maintaining water pressure. Every 100 gallons of imported water eats up enough electricity to keep a 100 W bulb lit for 11 hours.

  • What My Solor Roof Taught Me: Knowledge Really Does = Power
    by Sarah S. Mosko, Ph.D.

    My solar roof cost $15,000 to install after rebates and tax breaks, but the value of the house increased by $20,000 and the power bills decreased to $0.

    My solar roof cost $15,000 to install after rebates and tax breaks, but the value of the house increased by $20,000 and the power bills decreased to $0.

    I was pretty clueless when I recently installed photovoltaic (solar) panels on the roof of my house. All I knew was that all forms of energy consumption contribute to global warming (not just driving) and that I wanted to be part of the solution. I was nothing short of giddy when the “consumption wheel” on my electricity meter started turning backwards for the first time, veritable proof that I was generating more electricity than I was using. Energy was flowing from my rooftop right onto the grid.

    Elation soon gave way to curiosity, however, just like after I had purchased a hybrid Prius and could not help but experiment with ways to maximize my gas mileage. My new passion centered on how to insure an energy surplus on my next electric bill. Switching out the incandescent light bulbs in my house for energy saving compact fluorescent ones was a no brainer. But I also had to get acquainted with my household appliances along a totally new dimension:  I needed to know how much energy a given appliance consumes when in use so I could make more informed decisions when contemplating turning it on. Here is what I found out. Read the rest of this entry »

    Stay Married to Stay Green
    by Sarah S. Mosko, Ph.D.

    If you are looking for reasons to patch up a rocky marriage, here is one you have probably overlooked – do it for the planet! While it is common knowledge that divorce can be costly to the pocketbook, a recent investigation exposes pretty hefty costs to the environment too.

    Divorce is on the rise in the United States as evidenced by an increase in divorced households (households with divorced heads) from 5% to 15% of total households between 1970 and 2000. The proportion of married households (with married heads) sank from 69% to 53% over this same interval.

    One spouse typically moves out during a divorce. Michigan State University researchers Eunice Yu and Jianaguo Liu hypothesized that this splitting of families should translate into more but smaller households with loss of resource use efficiency on a per person basis. Their predictions were in fact borne out by tapping into the largest publicly available census based on individual U.S. households – the Integrated Public Use Microdata Series-USA.

    Installing solar panels on a little less than 30 million homes and businesses could power the entire nation.

    There is a wellspring of hope that 2007 is the tipping point in the fight against global warming.

    This is the year that the hundreds of experts on the Intergovernmental Panel on Climate Change concluded, with near certainty, that global warming is for real. It is the year Al Gore’s documentary An Inconvenient Truth turned “greenhouse gases” into an everyday household expression.

    With the finger of blame pointing squarely at the reckless burning of fossil fuels, renewable energy has become the hottest of topics. Whereas renewables of every ilk will most likely fill important energy niches, solar energy dwarfs all others in ultimate potential because of the sheer abundance of sunlight.

    Global energy consumption in the year 2004 averaged about 15 trillion watts (terawatts, TW), according to the U.S. Energy Information Administration. The amount of sunlight reaching the earth’s surface (120,000 TW) literally exceeds this global demand thousands of times over. In fact, Read the rest of this entry »
