For some, flickering lights are an annoyance and can be a distraction. Others don’t notice the inconsistency in the lights. But, that fluctuation in light can signal problems in the circuitry or light fixtures in one’s home. Depending on the source of the problem, it could lead to serious safety issues in a home.

All lights flicker to some extent, based on the amount of power that is coming into the lines in your home.  If your lights flash or flicker regularly, it’s often a sign that there’s a problem – either in connection or power use. Situational flickering – like when an air conditioner starts – is a sign that there’s an issue with power supply. Simply put, the dip of the lights when the AC unit starts up occurs because the AC pulls the available electricity supply from the light. It’s usually temporary. It may also be a sign that the outdoor AC unit isn’t wired for maximum amperage. If the flickering lights aren’t related to a large appliance powering up and running, it’s a sign that there are issues – home may be brighter and more comfortable.

Do you need more space for a growing family? One of the tradeoffs to buying a larger home is having to pay more in utility costs for heating, cooling and other appliance use. However, advances in energy efficiency mean that you can offset some of that increased consumption. That means you save money and worry less about your energy use, even if you just bought the mansion you always dreamed of.

Bigger Houses and Bigger Households

We like our homes bigger. The average American home size has grown  20 percent since 1980, and we've been filling those homes with ever more electricity-dependent devices, like televisions, computers and household appliances. Fortunately, over 70 percent of the growth in household and building size has been offset by efficiency improvements, according to the Energy Information Administration.

Total energy use by U.S. households inched up each year between 1980 and 2009, the EIA Residential Energy Consumption Survey reports. That is because of various reasons, including more households, larger households and a trend toward bigger houses. However, consumption per square foot actually dropped by 37 percent during that time period -- and if it hadn't, the total increase would have been considerably higher.

Residential energy accounted for 21 percent of total U.S. consumption in 2012 so the cumulative savings are significant. The numbers are astronomical -- residential usage increased from 9.3 quadrillion BTUs (British thermal units) in 1980 to 10.2 quadrillion by 2012 -- and without additional efficiency measures the total would have increased by another 3.6 quadrillion BTUs.

Multifaceted Efficiency Efforts

There are numerous factors driving the efficiency revolution: Stricter consumer appliance standards, local building codes geared toward efficiency and federal tax credits, in addition to awareness outreach programs and labeling efforts like the federal Energy Star program have all contributed to the reduction in consumption per square foot.

If you want to save the most energy, smaller is always better when it comes to houses. There's less space to heat and less to cool. However, if you need the extra space, take heart knowing that technological and behavioral improvements mean that a large house doesn't gobble up nearly as much energy as you might expect.

For more ideas on how to decrease your consumption, ask a home services expert to evaluate your home. He or she can help you find new ways to save no matter the size of your home.

It’s no secret that incandescent, fluorescent, and equivalent LED fixture. In California, Pacific Gas and Electric gives a $250 rebate for a 321- to 500-watt LED replacement for a high-bay fixture. Other utility companies will offer energy-savings-based rebates by each watt reduced or custom rebates, which require an energy audit. Products must be listed in DLC’s QPL to qualify for rebates. Contact your local utility company to verify participation in the rebate program or for a complete list of incentives and qualified products.

Purchasing an LED product on DLC’s QPL is rewarding in more ways than one; immediate energy savings and increased longevity are the most widely known benefits. DLC rebates are offered as an extra push toward quality lighting technologies. Incentives such as this one can be helpful in establishing a more sustainable, energy-conscious society.
