Light Bulbs, Energy Efficiency, and Cost

Energy Efficiency In Murrieta Homes

Light Bulbs, Energy Efficiency, and CostIn many countries, energy efficiency is also seen to have a national security benefit because it can be used to reduce the level of energy imports from foreign countries and may slow down the rate at which domestic energy resources are depleted. Energy efficiency is dictated by whatever process (such as coal-burning, hydroelectric, or renewable source) created the power. Greater energy efficiency is key to a clean, safe and secure energy future for all.

Another way to increase energy efficiency is to reduce or reuse the waste heat that is typically produced from manufacturing processes. Energy efficiency is the least expensive, most quickly deployable, and cleanest of all energy resources, according to research by ACEEE and other organizations. Energy efficiency is one of the easiest and most cost-effective ways to combat climate change, clean the air we breathe, improve the competitiveness of our businesses and reduce energy costs for consumers. In fact, energy efficiency is now the third largest resource in the US electric power sector, as shown in a new report we released today.

Choosing the Best Energy-Saving Lightbulbs

They’ve had a good long run, 134 years, but come January most screw-in incandescent lightbulbs will have been phased out because they use too much energy. There’s no need to hoard bulbs. Our tests found that new LEDs and CFLs are light-years ahead of earlier versions.

Standard 60- and 40-watt bulbs are the last to be phased out, though remaining stock can be sold; 75-watt bulbs faded away in 2012 and 100-watt bulbs this year. Their replacement equivalents, compact fluorescent lightbulbs and light-emitting diode bulbs, are bright, use 75 to 80 percent less energy, and can save you $60 to $125 dollars per bulb in energy costs over their life, compared with a traditional 60-watt incandescent. Because homes have about 50 lightbulbs, the savings can be significant.

But so is the investment. LEDs are expensive, up to $60 a bulb for some floodlights in our lightbulb Ratings. Even at that price, an LED can save you about $170 over its lifetime compared with a similar incandescent. Increased competition is helping to lower prices. Manufacturers told us that more $10 LEDs are coming next year, and there are already several bulbs in our Ratings for $20 or less. Read more here.

Despite the vital role energy efficiency is envisaged to play in cost-effectively cutting energy demand, only a small part of its economic potential is exploited in the Asia.

Electricity usage of an Incandescent Light Bulb

An incandescent light bulb also known as an incandescent lamp is an electric light with a wire filament which produces light when current passes through it. Incandescent lighting is cheap to produce but is very inefficient, converting only 5% of the energy into light.

Click calculate to find out the electricity cost of a single incandescent light bulb running at 60 Watts for 5 hours a day @ $0.10 per kWh, keep in mind you can edit the numbers in the calculator. Hours Used Per Day: Enter how many hours the device is being used on average per day, if the power consumption is lower than 1 hour per day enter as a decimal. (For example: 30 minutes per day is 0.5) Power Use (Watts): Enter the average power consumption of the device in watts.

Price (kWh): Enter the cost you are paying on average per kilowatt hour, our caculators use the default value of 0.10 or 10 cents. To find an exact price check your electricity bill or take a look at Global Electricity Prices. Incandescent light bulbs have an average lifespan of 1000 hours or 41.6 days running 24/7. While comparable CFL light bulbs last an average of 9,000 hours or 375 days running 24/7 and an LED light bulb lasts 50,000 hours or 2,083 days. See more here.

Household energy efficiency is necessary for meeting climate change and social policy objectives, are a long-standing target of US policy and are the focus of important new policy initiatives.

Energy saving light bulbs

In a typical home, lighting accounts for around 10-20% of the electricity bill, but if you change your old-fashioned incandescent lighting to more energy-efficient options, you can lower this proportion and save on your overall energy bill.

Lighting: eight top tips to save on your energy bills

  1. Only turn the lights on if you have to. Daylight is the most energy-efficient form of light.
  2. Turn off lights when you leave a room, unless you are going back within a few minutes.
  3. Choose low energy (compact fluorescent) lighting, there is a bulb available for virtually every situation and to suit all tastes.
  4. Avoid installing halogen lighting, especially the low voltage types which go in recessed fittings in ceilings and walls.
  5. Install low energy bulbs of the correct light output – to match the output you had with traditional lighting, simply divide by five to calculate the low energy equivalent. Read full article here.

Energy Efficiency Can Be Achieved In A Variety Of Ways

Improvements in energy efficiency are most often achieved by adopting a more efficient technology or production process. Energy conservation and energy efficiency are not only important topics for long-distance runners, they are also important when discussing our reliance on carbon-based fossil fuels. Even though energy conservation and energy efficiency are different practices, they both have the ability to limit our dependence on fossil fuels. Improving energy efficiency can not only soften the blow of increasing energy requirements, but it can also soften the blow on municipal budgets (electricity use for water and wastewater utilities is already a significant operating expense for municipalities).

National policies to improve energy efficiency are critical to job creation and economic development, reducing oil imports, improving the reliability of the electric grid, lowering energy prices, and addressing climate change and air pollution. Energy efficiency will contribute to reliability and security of energy supply, by decreasing losses at all links in energy value chains.  Energy efficiency can be a core strategy for not only tackling these threats but also creating more prosperous communities. For more information on how to save energy you may contact us here: (951) 805-1262, energy efficiency can make a big difference to all families.
