What more can I say. This is actually a pretty thoughtful list and like I said long. I will do the first 5 or so and then:

http://www.floridapsc.com/publications/electricgas/20summer.aspx

  1. Close shades, drapes and blinds during the day (all directions).
  2. Wear light weight clothing (short sleeves, shorts, cotton).
  3. Set the air conditioning thermostat at 78 degrees or higher. Raise it a few degrees higher when away in the day. A lower air conditioning temperature makes your costs much higher. Setting your air conditioner at 70 degrees instead of 78 can almost double your operating cost!
  4. Don’t choose a lower air conditioning temperature when you first turn it on. It won’t cool faster –- whenever it’s running it’s cooling as fast as it can. Set low, it cools longer, not faster.
  5. When weather is mild, use fans instead of the air conditioner. Your central air conditioner will use about 100 times more energy than a fan at medium speed.
  6. If you have ceiling fans, run the fans and the air conditioner at the same time but set the air conditioner a few degrees higher, to 80 or 81 degrees. With the breeze from a fan, you should feel as cool as you would at 78 degrees with no fans – but you’ll reduce your costs by about 15%-25%.

But then again they could be 10% of the population and the tips are supplied by Dominion. I mean really a producer advising you how to not consume. Still.

10 Tips to Save Energy and Keep Cool This Summer

  1. Raise your thermostat to 78º. This is the number one way to conserve energy.
  2. When you are away from home for more than eight hours, raise the thermostat setting and you can expect to see a 1% savings for each degree of setback. This will reduce the amount of energy used to cool your home while you’re away. You can learn more about your thermostat online by visiting the U.S. Department of Energy website.
  3. Keep shades closed when the air conditioner is on. Sunny windows account for 40 percent of unwanted heat and can make your air conditioner work two to three times harder.
  4. Check and clean filters. Cleaning and replacing air conditioning filters monthly allows the system to run more efficiently.
  5. Install ceiling fans. Don’t underestimate the importance of ceiling fans. Moving air over the body provides a cooling effect. The use of ceiling fans can mean savings of around 25% on cooling costs and can make the temperature seem 10 degrees cooler.

So I guess it is time to share some summer energy saving tips. This site is not bad. I mean it is California where they have to take energy use seriously. I know there are winter tips, and spring tips and there are even tips on tips.

http://www.consumerenergycenter.org/tips/summer.html

SUMMERTIME ENERGY-SAVING TIPS

These tips are designed to help you choose effective ways to reduce your energy bills. Some measures may not be relevant depending on climate, the age of your home and appliances, and past improvements made to your home.

The savings numbers are based on your total summer electric bill. Equipment mentioned must be electric powered for estimates to be accurate.

Also check out our What To Do Before It Gets TOO HOT! page.

 

FAST AND FREE

The average home spends about $1,900 a year on energy costs. But you can lower your energy bills and help save the environment at the same time!

Be a speedy chef

 

  • Nothing is more energy efficient for cooking than your microwave. It uses two-thirds less energy than your stove.

Push a button to wash your dishes

 

  • Surprise! Your dishwasher uses less water than washing dishes by hand. Then let dishes air-dry to save even more!

Fill up the fridge

 

  • Having lots of food in your fridge keeps it from warming up too fast when the door is open. So your fridge doesn’t have to work as hard to stay cool.

 

Cutting back unnecessary energy use is an easy way to reduce energy consumption while saving money. Here are some additional suggestions you can do at home, at absolutely no cost to you.

Building The Buildings Of The Future – No Air conditioning is a place to start

Posted on by

This is an old piece but it is still as true today as it was then. Air conditioning and by that I mean cooling air when it is hot is very expensive both financially and with regards to energy consumption.

http://www.greentechmedia.com/articles/read/buildings-without-air-conditioners-the-latest-in-energy-efficiency-5413/

Buildings Without Air Conditioners: The Latest in Energy Efficiency

Air conditioners consume an inordinate amount of power in the U.S. and they aren’t very efficiently used. To save energy, some say leave them out.

Michael Kanellos: December 22, 2008

Sometimes the most efficient air conditioning system is not having one at all.

To curb energy consumption, architects with projects in temperate cities – Seattle, Portland, San Francisco – have started to design buildings without mechanical air conditioners. These buildings will have heaters in all likelihood, but not air conditioning (see Can Greentech Make Housing Cheaper and Green Buildings No Subsidies Needed).

“There are only five days a year you need cooling in Seattle,” said Amanda Sturgeon, an architect and senior associate at the firm Perkins + Will, who recently designed a building without a mechanical conditioner.

In some cases, architects are putting in air-side economizers, i.e., computer-controlled windows that open to let in cooling breezes (see The Solar Window). The General Services Administration building in San Francisco uses openable windows on 12 of its 18 floors that let in cool breezes at night that, ideally, keep the offices cool in the daytime.  There is no mechanical cooling in the open office areas.

This shift comes courtesy of two trends. One, building developers and contractors have latched onto green buildings as an economic opportunity. Designing a building to LEED Silver or Gold standards – the environmental building standards promulgated by the U.S. Green Building Council – only adds around 2 percent to the overall cost or less, according to various contractors, architects and researchers. Designing to the LEED Platinum standard can add only 6 percent if carefully planned. The trick, say Sturgeon and others, is to exploit as many passive, design-centric techniques for scoring LEED points before moving on to the potentially more expensive, equipment-centric ones like biomass boilers or new types of lighting systems.

Dominion is an energy company so this is actually sort of progressive. I say sort of, because if they offered real programs for solar water heaters, solar photovoltaics and geothermal at the residential level they would be on the right path. But one baby step after another I guess.

Spring Cleaning? Add energy efficiency to the “to do” list and save money.

‘Tis the season for the chore called Spring Cleaning. For me, I have to motivate myself to get ready to clean (not my favorite household chore). But this year I am thinking about it positively, thinking of all the energy I will save.

There are some chores you may want to add to your cleaning list that will help you save energy and money leading into the cooling season.

  • Dust the lamps and lightbulbs. The dust and grime on the bulb makes it dirty, reducing the amount of light it gives off.
  • Clean your air filter. Replacing air conditioning filters allows for the system to run efficiently.
  • Clean the air return vents. Make sure drapes and furniture aren’t blocking the vents.
  • Vacuum the refrigerator coils. The dust builds up, causing the fridge to run less efficiently.
  • Thoroughly dust electronics and then unplug them when not in use.
  • Scrub the tub and then install low flow showerheads.

Spring into Energy Savings

clock April 14, 2009 06:00

No winter lasts forever; no spring skips its turn.
– Hal Borland

In my part of the country, winter seems to hang on an interminably long time. So I always look forward to the first signs of spring with unbridled glee. At the first glimpse of a cherry blossom, the winter boots are banished to the back of the closet and the sandals are put to work in earnest.

But while spring may give the perfect excuse to hang up the winter coat, the advent of spring does not mean that we can pack away thoughts of energy efficiency with our wool sweaters. Last winter, Jennifer Carter gave us a number of great energy efficiency tips for winter. Now that spring’s milder temperatures are upon us and it’s time to consider what energy efficiency means in warmer weather, the Office of Energy Efficiency and Renewable Energy’s new Stay Cool, Save Money website is a great resource for efficiency tips. The site has a wealth of no-cost and low-cost advice that can help you lighten your energy load without lightening your wallet. And, for those ready to make a more long-term investment in energy savings, the site has resources to help you make well-informed decisions to get the most bang for your energy buck.

The following tips provide a taste of the energy saving-strategies that the Web site has to offer

Spring Has Sprung In El Paso – They want you to throw open your windows

Posted on by

These tips are really kinda lame but at least they are trying.

http://www.epelectric.com/nm/business/spring-energy-efficiency-tips

As you’re doing your spring cleaning and getting your air conditioner, as well as your house, ready for the hot weather, consider making some changes around the house that will help save energy dollars this summer.

When cleaning windows, check to see if they’re in good condition.  Loose, leaky or single-paned windows allow heated or cooled air to escape, taking hard-earned dollars with it.  Repair existing windows or replace them with energy-efficient models.

  • If you leave your windows open to enjoy the weather, remember to shut off the heating system.  A thermostat will call for heat when it’s set to a temperature higher than the outside air.
  • Clean under and in back of the refrigerator.  Dust can build up in those hard-to-reach areas, causing the refrigerator to run less efficiently.  If you have an old refrigerator that was manufactured before 1993, consider replacing it with a new Energy Star-rated model.  They use half as much energy as models manufactured before 1993 and 15 percent less energy than other new models.  This change can save you hundreds of dollars a year.
  • Unplug the old, inefficient refrigerator or freezer that’s in the garage – it’s wasting energy and money.  If a second refrigerator or freezer is needed, keep it full.  Water and ice work well for this.
  • Dust or wipe light bulbs.  Clean bulbs provide more light for the money.  Replace high-use incandescent bulbs with compact fluorescent bulbs and fixtures – they use two-thirds less energy and last up to 10 times longer.
  • When washing clothes, adjust the water level to match the load size, and use cold water whenever possible.  Use the dryer’s moisture sensor option that automatically shuts off the machine when the clothes are dry, and clean the lint filter before every load.  Consider hanging clothes outside to dry instead.

Utilities Go Trenchless – And cut costs

This is great news for the safety of the industry.

Advances in utility location

Jo Parker

Trenchless International — October 2009

Advances in underground utility location could mean enormous savings – in economic, environmental and social terms. Here Jo Parker from Watershed Associates discusses some of the latest technological research and development emerging from the UK.

There are over four million kilometres of buried assets in the UK. At present, utilities make information about their buried assets available in a variety of methods including via websites, through telephone or written application, with a paper plan sent in response, or by marking out the location onsite. Collating these records can be a time consuming exercise and often the information has to be transferred by hand to another CAD system.

Even when a utility company uses the latest techniques to map its new assets, information on legacy services – which may have been installed decades earlier by a predecessor organisation – may be inaccurate or even non-existent. Pipes in older cities may be over 150 years old. Poor mapping techniques used at the time of installation and the practice of recording the pipe’s location relative to a physical feature that may no longer exist means the exact location of many of today’s networks are unknown. Although current surface location and detection techniques have improved in recent years, they are still of limited use, being both unreliable and slow to operate. As a result the only way to reliably identify the accurate position of any buried service is to excavate a trial hole.

Economic disruption

The direct cost of trenching and reinstatement work of UK highways for utilities is in excess of £1.5 billion per year. Part of this is attributable to holes excavated in the wrong location and damage to third party assets, which is estimated to be as high as £150 million. Although direct costs are high they are significantly lower than the societal costs, such as delays to road users, disruption to businesses and environmental damage which may be as high as £5 billion per year.

Off Grid Living-You Can Do It Too

January 21, 2009

More and more people are realizing that you can still enjoy modern amenities while enjoying the independence of off grid living.  Being off the grid means being exactly that, off the grid.  No power lines, no electric bills, and being free of utility grid demands, not to mention their ever-rising rates.  Off grid living is environmentally friendly and cost effective and it is an option available to almost any one owning a home.

The principles of off grid living may be applied to any home in the world, even those currently tied to the grid.  From solar panels, hydro power and windmills, there is growing curiosity in off grid living and breaking free from fossil fuel burning power plants.  The technologies have advanced and the costs have dropped greatly.
Even do-it-yourselfers can take leaps into off grid living with many kits, resources and manuals available for instruction.  As energy demands increase globally, those living off grid can rest easy knowing their own energy costs are diminishing.

The idea of off grid living can be scary to some who believe they will have to give up some of their most prized possessions and electronic gadgets to achieve such freedom.  This is very far from the truth.  Off grid living is simply about learning to moderate your use of electricity.  It can be as simple as turning off lights that are not really in use.  Purchasing appliances that don’t use energy when not in use (like clocks on microwaves and stoves).  Learning to unplug, not just turn off.  Things like computers and printers, well anything with the little green light that is always on, these items are stealing precious energy and adding to your bill.  Wanting to become part of the off grid living adventure, doesn’t always mean giving up everything, sometimes it just means getting smarter about the things you have.
