6 reasons your electrical consumption changes

Your electrical consumption changes, this post will help you figure out why. Understanding the factors that cause your electric usage to increase or decrease will help you set more achievable clean energy generation and energy efficiency goals. The following 6 reasons are related to changes in your electrical consumption: Seasons change obviously, in the summer the air conditioner bumps up your electric usage compared to the rest of the year. depending on your home, people may move in or out. As your appliances get older they become less energy efficient. You will get rid of some appliances over time. You forget to turn things off. You buy new stuff that adds to your electrical loads. Can anyone else think of a reason your electric consumption increases or...

25% solar cell efficiency, a world’s record.

Last month, I wrote about Suniva a company that recently developed a 20% efficient solar cell. Today, Total Solar Energy, a frequent commentator on our blog pointed out that the New South Wales’ ARC Photovoltaic Centre of Excellence in Australia has the world’s record for most highly efficient solar cell at 25%. Recently, there has been changes in the international standards of how solar cells are measured in terms of a better understanding of atmospheric effects upon the colour content of sunlight. It’s now observed that the blue sunlight spectrum is absorbed strongly, very close to the cell surface on the flip side red sunlight spectrum is weakly absorbed. The cell developed by the ARC Photovoltaic Centre has a special design to trap the red sunlight spectrum more efficiently. First generation solar cells have a theoretical maximum of 29% efficiency according to scientist, solar cell technology is getting close to maxing out the first generation efficiencies. When do you think we will see 50% efficiencies? Solar cell technology is evolving so fast, does anyone know of a solar cell that has an efficiency of over...

windows that lower your energy bills

Rainbow Solar, Inc. introduced a semi-transparent “photovoltaic glass window” over the weekend that turns light and heat into electricity. The window of the future is in production and is ready for the US market. The company is working with building developers to integrate the photovoltaic windows into projects in Hollywood and Las Vegas. The transparent photovoltaic-glass window not only produces 80 to 250 watts of power output but can achieve a reduction of heating and cooling costs up to 50%. Windows that produce electricity and help keep temperatures comfortable inside a building will be a standard in building projects moving forward. The RSi PV-Glass Window has proven energy savings greater than 50% in a hot-house test with a skylight, according to a study conducted by the NTUST (National Taiwan University of Science and Technology). Photovoltaic glass window is an example of building integrated photovoltaics, which is a term that means integrating solar cells into traditional building materials such as windows, roofing shingles, sides of walls…etc. Do you think building integrated photovoltaics (BIPV) will be the future of solar...

Energy efficiency or conservation? What’s more affordable?

I had a chance to think about the difference between energy efficiency and energy conservation today. These terms are showing up more often these days because more people want to reduce their impact on the environment but I don’t think many people understand the difference between the terms. An example of energy efficiency would be if you changed your light bulbs from incandescent bulbs to LED bulbs or upgrading your insulation, you have to buy products to become more energy efficient. On the other hand, energy conservation is making lifestyle changes to use less energy all together. For example, turning off the lights when you leave a room, adjusting your thermostat, being aware of your energy usage in general and making adjustments in your lifestyle to save energy. To save money on your energy bills without any investment in solar panels, wind turbines or energy efficiency products, think about energy conservation since it’s something we can all do if we set good energy habits. Here in the USA, most of us have grown up with very reliable and abundant electrical service, so its easy to get into the habit of wasting energy, don’t you agree? What have you done to become more energy efficient or have you came up with a creative method to conserve...

Top 10 Vampire Loads to Kill

It’s too bad you can’t kill vampires that feed off your electric bill with a wooden stake through the heart. Vampires also known as phantom loads are electrical devices that consume power even when they are turned off. Vampires are small loads that consume power 24 hours a day, 7 days a week. The constant consumption adds up to significant amounts on your monthly electric bill. Solar Power best practices recommends you should become more energy efficient before installing solar panels, to get the maximum benefit out of your solar electric system. You can use a smart power strip to kill the following top 10 vampire loads: 10. Video Game Console9. Radio8. Cordless Phone7. Answering Machine6. Microwave5. TV4. VCR3. Dishwasher2. Cable TV Box1. Home Security System Vampire Loads are costing U.S. consumers 3 billion dollars per year! Unbelievable, isn’t it? How much is it costing you? Have you came up with any interesting ways to kill your vampire loads? If US consumers set a goal to reduce their vampire loads this year, it would be one massive economic stimulus, wouldn’t you...

LED – High efficiency light Bulbs save you money

Many people dream of eliminating their entire electric bill by using solar panels or putting up a wind turbine, although that dream is out of their reach because of the high upfront related with an energy hog’s electric consumption. When you are energy inefficient, eliminating your energy can be associated with a very high upfront cost. Although you have the power to reduce your consumption by looking into energy efficiency there are product out there such as EarthLED high efficiency light bulbs that can reduce your consumption significantly and save you lots of money on electricity costs. LED light bulbs are very reliable, many people don’t know that the average lifetime of a LED bulb is over 10 years! Imagine just the cost savings of not having to replace a bulb for the next 10 years. LED consume only a couple watts of electricity, therefore only cost a couple dollars in electricity costs to run the entire year and their are just as bright at traditional light bulbs. The case study above shows a building that replaced 1100 light bulbs with EarthLEDs, not only did the building actually lower the temperature in the building by a couple degrees, but the amazing aspect is that they are saving 450kWh a day! Based on the cost of electricity of 10 cents per kWh and comparing it to the total cost of 1,100 EarthLEDs the building would break even within 5 years on their investment. The calculation did not include the cost of changing light bulbs or factor in energy inflation and rebates received for high efficiency light bulbs, with those variables factored in we’re looking at a break even point lower than 5 years. Why not CFLs? Well, CFLs have a lower upfront cost, although they also include mercury with is a pollutant that is bad for the environment and CFL light bulbs are not as efficient as LEDs, plus you have to replace CFL light bulbs more often. Taking those points into consideration, the LED light bulb does make more environmental and economic sense. Lighting is typically 10% of the electrical demand of a building, by using LED lights to lower your consumption first in the future you would need to buy less solar panels or wind turbines to eliminate your electricity bill. It’s always more affordable to reduce energy consumption then produce your own. Solar Panels and LED lights make a very cost effective partnership. So what do you think about LED bulbs? looking forward to your...
