Solar Farm

From science fiction to massive solar plants in the American West, solar energy has fascinated and tantalized scientists and writers for generations.  The promise of easily-accessible, virtually free energy from the large fusion reactor at the center of our solar system (the sun) is enticing and we’re getting closer to harnessing its power effectively every day.

Solar power is interesting because it’s one of the few electrical energy systems that does not use a turbine to generate energy.  Photoelectric cells contain a material that releases electrons when hit by a photon, generating electrical power.  There are no moving parts, no fuel to burn and pay for, and only occasional maintenance to keep the system performing optimally.

So what is holding back the proliferation of solar energy?  Space and storage.  We can generate large quantities of energy from solar, but we do not, at present, have the right method to store that energy for periods without sunlight (night time and storms).  So far the best response has been homeowners installing solar cells on their own homes with battery storage systems linked into their own neighborhoods.  By splitting up generation and storage within the neighborhood itself, enough solar cells can be installed to generate energy both day and night.

Space is at a premium when it comes to energy generation.  Solar power plants take up more space than traditional plants, while generating less energy per square foot.  Because solar cells need to be placed over large areas to maximize sunlight, installing power plants in urban areas can be difficult.  Though installing solar cells on your home can be done simply.

We mentioned self-starting or “œblack-start” energy systems.  These systems can be started without power applied to the system, a huge benefit to fuel-fed power plants, and necessary in the event of major blackouts and power losses.  True, we can supplement with gas turbines or nearby power generation, but we also want black-start renewables.  Fortunately, hydroelectric power plants require no off-system power to function.

Hydroelectric plants are special because, while they also have a somewhat variable energy source, they also have one of the best energy storage systems available: potential energy.  Hydroelectric dams use flowing water to spin turbines, typically generated from lakes and rivers.  Rather than storing generated electricity, hydroelectric plants can store water at a higher altitude.  By storing water in special tanks, they have access to electrical generation potential by simply releasing the stored water and allowing it to spin the turbine.  Hydroelectric power is perfect for energy storage, but they’re limited to specific areas.

Good News! Electric vehicle-related jobs in Los Angeles grew by 15.3% between 2007 and 2010. While the number of these jobs is still small, totaling a little over 550 in 2100, the growth rate is a hopeful sign and is a small part of the overall growth in our green economy jobs. The growth rate in L.A.’s green economy jobs between 2007 and 2010 was 7.1%, yielding a total of over 89,000 jobs in 2010.

L.A. scored #3 in growth rate for electric vehicle-related jobs between 2007 and 2010, with Kansas City at #1 and Phoenix at #2. “Electric vehicle-related jobs” includes manufacturing of electrical equipment and other parts for electric cars. It doesn’t include, for example, what we at The Electric Connection do, install chargers for electric vehicles (EVs), nor the selling of electric cars. Nor does the 2007-10 growth rate include small companies of 5 or fewer employees. For these reasons, the 15.3% figure for 2007-10 is undoubtedly an underestimate of job growth in the Los Angeles area related to electric cars.

However, the figures are an indication of an exciting phenomenon occurring all over the country — the growth of the green economy. The green economy encompasses recycling, energy audits, solar cells, and other industries which, like EVs, have an environmental benefit. The growth of the green economy benefits not only the environment, but also has a particularly welcome benefit of creating middle income jobs that don’t require higher education.

Yes, many green economy jobs go to environmental engineers, computer programmers, and others who have gone to college. In fact, many of these college-educated people are the innovators who create the green jobs to begin with.

But many green economy jobs, like in the manufacturing of electrical parts for electric cars, don’t require a college education. People are calling them “green collar” jobs — jobs that can be filled by people who might otherwise fruitlessly look for blue collar jobs that have been lost to robots in manufacturing plants or have been shipped overseas to people who make low wages.

We’re experiencing a process that has repeated itself throughout history — innovation seeding job creation. When Scottish engineer James Watt created innovations that made the steam engine useful commercially, he made the Industrial Revolution possible. The Industrial Revolution started with steam-powered textile plants. Textile and other steam-powered manufacturing plants led to the creation of factory jobs, which at that time, required limited education. This allowed subsistence farmers to leave their fields and begin (in an admittedly arduous path!) upward mobility. This was the rise of the Middle Class.

Today, the green economy, created by innovation, yields both green collar jobs and those requiring higher education. The growth of jobs in the EV manufacturing sector in L.A. is good over the long term not only for our environment, but also for our job market, providing work for people with various levels of education.

There are different things that you may do in order to see to it that you will be making the most efficient and the best possible use of the energy that you channel into your home. There are different options that you may tap in order to determine whether you have to make certain adjustments in your home’s energy system, one of them being Princeton energy efficiency audits. If you own a house and if you still have not had this process performed in your home, then it is highly advised that you do so in order to save.

Home energy audits allow you to carefully and efficiently pinpoint the energy needs that the different pieces of equipment in your home mount up to. Going through this process will give you an idea of how much energy you really need in order to keep your household running smoothly.

By having a professional audit done, you will not only allow you to see to it that you will have ample supply of energy for the different parts of your house, but will also keep you from overshooting your expectations and supplies. Without having to say it, you will be able to efficiently channel enough energy into the different parts of your home and ensure that you will not be using up more than necessary.

There are different standardized tests that are employed in order to determine the amount of power and energy that you need to have your home equipment run effectively and efficiently. More than measuring the needs of your whole house, you may even have other tests employed for individual rooms and areas, allowing you to map out and determine the energy needs and consumption that you may expect from the different areas of your house.

When you get the time and want to save on your monthly energy bills, it will be best for you to have Princeton energy efficiency audits done. tests employed to ensure that you ware able to make the most efficient use of your home energy.

Needless to say, home energy audits are always performed by professionals. Unless you have some type of background in the electrical/ energy field, it will be impossible for you to even know how to employ the necessary tests.

Don’t worry about finding the time to test the energy using devices in your home. Drop your local electrician a line and he will most likely be willing to perform this job for your home. Princeton energy efficiency audits can save you time and money when done right.

From the 1950s to the 1980s, the Federal Pacific Electrical Company (FPE) installed electrical panels in millions of homes across the country. Unfortunately, these electrical panels are basically recipes for disaster—over the years, electricians and home inspectors have found that FPE panels often fail to protect homes from overcurrent or short circuits. The danger seems to happen randomly: even if panels have been installed and working properly for years, a single incident can quickly cause the panel to overheat and create a major fire hazard.

Remember—circuit panels trip in response to unusual surges of electricity. If they fail to trip, as FPE panels often do, those electrical surges cannot be stopped or shut off manually and will move through your home until they run out of fuel or until the wires burn out. This could cause the panel to overheat and catch fire, leading to a potentially serious disaster.

FPE panels may not be up to modern safety codes – electrical safety standards have been updated significantly since the 1980s, and experts say that FPE panels, which were produced from the 50s and into the 80s, do not meet these updated standards. Some of the deficiencies noted by home inspectors include:

FPE panels may have serious design flaws – not only do FPE panels not meet modern safety standards, but they also came with some serious design flaws that weren’t even common among panels built around the same time. Some of the most significant flaws include:

FPE panels may have manufacturing defects – as if that weren’t enough, the Consumer Product Safety Commission (CPSC) has noted a number of defects that make FPE panels unfit for homes, including weak materials used to construct the breakers that may prevent them from tripping and could cause the panel to catch fire.

If you live in an older home and you’re worried your panel might be a danger, call Kolb Electric. Our trained electricians are familiar with the potential hazards of FPE and other outdated panels and can replace your existing panel with a modern panel that will keep your home safe for decades.
