We’ve begun installing chargers for electric cars in Los Angeles – thus my new interest in electric cars. Interest in electric cars (electric vehicles or EVs) is picking up because the Nissan Leaf just began deliveries in L.A. in December and the Chevy Volt is supposed to start deliveries early this year. Los Angeles buyers are starting to install electric chargers for these vehicles, and I’m starting to learn a lot more about EVs.

Of course, as someone who installs chargers for electric cars, I’m interested in how many will be sold in Los Angeles. Sorry folks, no one really knows. Forecasts are all over the board. Pike Research, a transportation analysis firm, just projected in early 2011 that in the next six years, between 2011 and 2017, over 96,000 electric vehicles will be sold in Los Angeles. It projects that Los Angeles purchases will be second highest in the country, trailing only New York City. Its overall projection is 366,000 EVs  sold nationwide by 2017.

Another study in 2009 by the University of California, Berkeley (Center for Entrepreneurship and Technology) projected that the U.S. will hit 1,000,000 EVs sold by 2017. This is still far lower than President Obama’s call for 1,000,000 by 2015, which many analysts consider realistic.

Why are the projections so different? The U.C. study explains. It mostly depends on the price of gasoline. For example, if gas prices continue at about $3.50 a gallon, U.C. forecasts only 18% of new car sales will be electric in 2020. But if gas prices rise to about $5.50 a gallon, the forecast rises to 45% of new car sales in 2020. Of course, experience tells us that gas prices move up and down very quickly and unexpectedly, often depending on events in the volatile Middle East.

The safest statement one can make about electric cars sales in Los Angeles is that they’re starting in a big way now and will continue to increase over the coming years. Another safe statement – buying an electric car and installing a charger is going to protect you from the wild ups and downs of gas prices, something no one can predict.

Fans in the attic? The idea at first may sound odd. We usually think of fans as blowing somewhere in our home where we can feel their effects, like hanging from ceilings or mounted in windows. Few people spend more time in their attic than they absolutely must, so it seems useless to install fans there.

However, attic fans can form an important part of maintaining the overall efficiency of your air conditioning system. If you’ve taken all the steps you can to keep your HVAC system working its best (regular maintenance, duct cleaning, changing the filter, proper insulation), attic fans will take you a step beyond. We’ll explain why putting in attic fans will benefit you.

Attics are both heat traps and heat escape routes. You can use insulation to stop heat from escaping in winter, but what about summer, when heat gathers in the attic and creates excessively high temperatures that will seep into other parts of your home? (Go up into your attic on a hot day and see what it’s like. It can be miserable. You don’t want any of that to get to rooms you actually use.) To stop summer attic heat, you’ll need attic fans.

Attic fans should be wired to a thermostat that will turn the fan on based on the temperature. This saves energy since you won’t have to keep the fan on constantly or continually check on it. The movement of air in the attic will lower the high temperature.

The first benefit is the most obvious: your home will not get as hot during the summer. On average, the temperature in the attic will decrease 50 degrees with a fan, which means a drop of 10 degrees in your house.

This not only translates into comfort, it also means savings on your energy bills. A cooler house requires less work from an air conditioner to cool it. You’ll spend less, and your air conditioner will not receive extra stress that will lead to repairs and possibly an early replacement.

Attic fans will also extend the life of your roof. Rising moisture in your home will get into the roof, eventually creating mold in the insulation and the roof material. In winter, the freezing moisture can be extremely damaging. Attic fans move moisture away and keep it from settling.

Your circuit breaker serves the same function that the fuse box once did; it is responsible for the safe distribution of electricity throughout your home. The current is broken up onto different circuits, and each circuit will have a breaker in the box. Certain appliances may be on a designated circuit, while other circuits will cover an area of the home. When the power running to any circuit reaches overload levels, or if there is a fault of any kind on the circuit, the breaker will trip, stemming the flow of electricity until the breaker is reset.

Generally speaking, an overloaded circuit is the cause of a tripped breaker. This prevents overheating on the circuit, and is a very important safety measure. Short circuits are also possible causes, and are more concerning. Essentially, this occurs when a hot wire touches a neutral wire in one of the outlets on the circuit. This can cause a spike in current flow, and can result in overheating of the circuit, which will trigger the breaker to trip. Crossed wires are serious business, so contact us if you suspect that you have any such issues. Ground faults are a third cause, and are similar to short circuits in that a hot wire touches the ground wire within an outlet box. No matter what is causing your breakers to trip, you should schedule professional service if it is a frequent problem.
