Dirty Old Coal is back on the agenda. Due to public and goverments’ panic around soaring oil prices (which seem to be on the decline again), there are plans the world over for more coal-fired power plants: India has plans to build another 73 coal plants in the next 10 years. There are plans to build over 150 new coal plants in the US in the next few years and my understanding is that China, Germany and the UK all have coal plants somewhere in the pipeline.

The world seem to be divided today between those who wants to go 150 years back and those advocating to invest all our resources in developing green and clean energy technologies. After reading few articles on this topic I must admit I’m rather confused. Coal has a high potential in future energy supply, only once new technology to reduce CO2-emissions from coal combustion will become economically viable. But currently they aren’t and the fact of the matter is that 40% of the global carbon dioxide emissions are due to coal.

If you want to read more on this subject you should read the debate between George Monbiot and Arthur Scargill few months back in the Guardian. The EU Energy Policy Blog also written some illuminating facts about the future of coal-based energy.

The reason for this lengthy introduction is a new Greenpeace campaign. Inspiring, engaging environmental campaigns are difficult to pull out. Especially these days, when the economic meltdown is contributing to the already short and fatigued attention span of the general public in relation to green issues you have to produce something that will stand out and cut through and I think that Greenpeace have managed to pull a nifty little campaign called….CoalFinger:

The campaign is topical and full of funny moments and the microsite is nicely designed with clear, plain English articulation of the problem.

Well done Greenpeace.

When talking green, people naturally tend to focus on vehicles, but the fact is vehicle emissions have nowhere near the impact that the building industry does.

Buildings and homes use more energy and are responsible for over 35% of all man made greenhouse gases and energy used worldwide. By “greening” every structure with existing technologies and techniques, the world would see a reduction in CO2 by over 1,800 megatons per year. That is equal to the amount of CO2 released by all planes and vehicles in North America last year.

With energy cost rising at a steady pace, energy efficiency renovations are the most cost effective ways to green a home or building, even more so than investing in alternative energies. Increasing efficiency does not have to be a daunting task, there are plenty of quick and easy things you can do which are not very involved. Below is a list of 10 things you can do to increase your efficiency and they are listed from cheapest and easiest to more expensive and involved.

10 steps to Energy Efficiency:

1. Reduce Phantom Loads - phantom loads are those unforeseen “standby” electrical loads that rob about 11% of annual energy consumption. Most electrical products have standby electrical loads which use electricity even when the product is turned off. DVD players, TV’s, Computers, phone chargers, and many other products all use electricity on a constant basis. The solution is to plug these things into surge protector strips and turn the strip off when they are not in use.

2. Seal Up Leaks - Air infiltration is a major cause of increased energy usage. When a structure is not properly sealed, heat will be lost during the winter and gained during the summer, driving up heating and cooling cost. The solution is to perform a pressurization test to locate air leaks and use some sort of caulk or silicon sealant to seal the air leaks in your walls and ceilings.

3. Weatherize - Weatherizing is very similar to sealing air leaks, however, it is different in that it is applied to moving parts such as doors and windows where a caulk type sealant will not work. Weatherizing doors and windows require special products such as v-channel, foam strips and sweeps. For a more detailed tutorial about sealing and weatherizing your home or business, check out “Air Leaks & Energy Exchange” over at NeutralExistence.com.

4. Change Lights - Inefficient lighting is responsible for not only wasted electricity, but added heat gain. The incandescent light bulbs of yesterday are slowly being phased out to more energy efficient Compact Florescent bulbs and LED lightbulbs. A new energy efficient CFL bulb can save about 150 kWh of electricity annually and save you approximately $37 over the life of the bulb. LED lightbulbs, although more expensive up front, will last much longer than CFLs and use less energy as well.

5. Control Radiant Heat - Radiant heat is the most efficient form of heat transfer and in order to increase a structures heating and cooling efficiency, radiant heat transfer must be stopped. Radiant heat is responsible for excess heat gain in the summer and heat loss in the winter. The only way to stop radiant heat transfer is by using a radiant barrier which is a sheet of low emisivity, high reflectivity foil. Although radiant barriers come in many shapes and sizes, but be sure to find a well made, durable, two sided (for winter and summer protection), perforated radiant barrier. I highly recommend Ra-flect radiant barrier as a cost effective quality product (www.raflect.com).

6. Increase Water Efficiency - Massive amounts of energy are used to treat and move potable (drinkable) municipal water, so reducing water usage very energy efficient. There are a variety of things you can do to reduce your potable water usage such as using low flow faucet and shower fixtures, taking shorter showers, only running dishwashers and washer machines when they are full, not leaving the water running needlessly and using water banks in toilet tanks to reduce water used to flush toilets.

7. New Insulation - Insulation retards the passage of convective and conductive heat and is rated in R-values, which is the measure of the rate that heat energy is transferred through a material. If your insulation has been pressed down over the years or the R-value is not the proper value for your location, re-insulating your home is well worth the expense. In order to choose the most efficient insulation for your home or building check out the Energy Star website to find out: www.energystar.gov

8. Window Renovation - Windows are generally the most significant energy sink in almost every structures due to lack of insulation. Windows come in a variety of configurations such as single pane (not efficient), double pane, gas filled, mirrored, etc.. In cooler climates gas filled double pane windows with high R-values are excellent and well worth the cost of replacing old single pane windows. In hotter climates, these same windows are not as effective as they only reduce convective and conductive heat gain but fall short in stopping radiant heat gain. Stopping radiant heat gain in hotter climates requires exterior shading elements or the use of an energy film which helps to block the suns UV rays. Window energy films are applied directly to the glass with soap and water and will essentially make an existing window perform like that of an energy star rated double pane gas filled window.

9. Energy Star Products - Energy star is a governmental rating system which gives its seal to products, buildings, homes and devices which meet minimum requirements of energy efficiency as compared to the norm. When buying new devices such as refrigerators, washer machines, dishwashers and home electronics be sure to purchase products with the Energy Star seal as they will use less electricity than their competition. For more information about energy star and there rating system please see their website (www.energystar.gov).

10. Build Green - In order to increase your energy efficiency build green instead of buying an already made home or business. The benefits of having an architect design a green home or business for you are too many to count. Some benefits of building green include increased energy efficiency, better interior air quality, higher resale value, higher rental rates and occupancy rates for businesses and not to mention, you get the house or building that meets YOUR needs, not some generic home or building which may not be sized appropriately.

Efficiency IS greener than green

Anyway way you look at it, there is no getting around energy efficiency if you really want to green your lifestyle. Efficiency does not have to stop at your home or business, the idea of efficiency can be used in every aspect of your life, from shopping for products to driving around town, efficiency is the key to being green,

Living in Southern California we get plenty of sunshine (though admittedly it is currently raining). It’s therefore usually an ideal spot for home solar panels, however speaking with various people about it there are some common misconceptions, some conflicting, that people have.

1. It takes 30 years to get your money back. Of course it depends where you live, what type of system you have and how much energy you use. Here in California, 6-8 years is more the norm. Plus, don’t think of it as getting your money back, think of it as an upfront cost that then provides you something for free.

2. If there’s a main power cut in your street, you will still have electricity. No, this isn’t normally correct, almost all systems are “grid-tie” systems. This means you receive power from the national grid as normal, and your solar panels send any electricity generated to this grid, essentially using the grid as a battery. If there’s a power cut then you will not be able to receive any power from the grid or your solar installation.

3. The electricity company will pay you for any extra energy you produce. This isn’t usually true. Your solar installation will, at times, be generating more electricity than you are using so your electricity meter will start going backwards. Over a 12 month period, if you have generated more electricity than you have used, you will NOT get any money for this, therefore it is very important to size the system you have to the amount of electricity that you use. Else you will be paying to build a bigger system than you can benefit from.

4. The government will give you massive rebates. Once again this depends on where you live and what current rebate program is in effect. It’s not uncommon to get 50% or more back in rebates and tax credits, however you should investigate this and apply before you order anything. It’s usually calculated on a per watt basis.

5. My condo owner or Home Owners Association won’t allow it. In California it’s against the law to restrict the installation of solar panels. They can make demands on how it looks, position etc, but nothing that will add more than 15% to the cost. It’s likely to be similar wherever you live - the government want you to pay to create your own energy!

6. It’s difficult to install, and looks ugly. No, it’s actually relatively quick and simple (less than a week depending on the size), but there are hundreds of companies that are licensed and will do it for you. As to whether it looks ugly, well, that’s in the eye of the beholder!
