Kohl’s Stores Are Going Green and Giving Back
Kohl’s Inc. – a retailer with almost 1,100 stores in the United States – made news recently by announcing its plan to bring solar energy to ten of its stores in Colorado. According to Newsweek, Kohl’s “[h]as the largest solar power program of any retailer globally.” Currently, eighty-six Kohl’s stores in Maryland, California, Connecticut, Wisconsin, Oregon, and New Jersey use solar power.
In addition to its solar power initiative, Kohl’s plans to donate $2 million to nonprofit organizations in honor of Earth Day and National Volunteer Week, and Kohl’s A-Team Volunteers – comprised of Kohl’s employees – will practice environmental responsibility by participating in environmental initiatives throughout the month of April.
At a time when some companies are only going green because it pays to go green, it is always good to hear about a company that is actively contributing funds to environmental causes.
Acts for the Earth!
‘Tis that time of the year for the largest secular celebration around the World, Earth Day!
With over 1 billion participants, this 40 year old holiday spurred on by a U.S. Senator from Wisconsin, Gaylord Nelson, continues to grow. The Earth Day Network and the Nature Conservancy are promoting “Acts” for the Earth. A little reminiscent of New Years Resolutions, these “Acts” of green help us commit to living more sustainably.
The Nature Conservancy’s Top 5 “Acts of Green” for Earth Day:
These “acts” cover the gauntlet from daily actions to lifestyle changes and donations. Integrating some of these helpful lifestyle tips with other goals of your own, like buying clean energy or reducing our footprint, can be part of your own plan for “Green Acts”.
Anyone want to share what they are up to or committed to for this Earth Day?

Silexium Could Change Solar Panel Manufacture
Sixtron has recently developed a thin coating for solar cells called Silexium. This anti-reflective coating could make solar panels much more affordable.
The manufacture of solar cells now requires the use of saline gas to make anti-reflective coating, that is extremely dangerous as well as expensive. Silexium does not require silane to be present and could reduce the complexity and money required to make solar cells. This new coating would also provide more protection over the cells allow for possibly longer life and more power generated.
Sounds like a promising product that could help expand the usage of solar panels.
Understanding and Evaluating Energy Saving Technology
With the recent climate change talks in Copenhagen, it is safe to say that even though all countries aren’t actually making an effort to change their actions, most at least understand it is extremely important for the environment for us to change our ways and focus on reducing pollution.
Rather than waiting for our politicians to step up and mandate the changes needed to help save our environment, I feel that it is our duty to help make this world a better place, after all it is the only one we have.
One of the most effective ways of doing this is to help cut down on our energy costs, both in our vehicles and at home. However, when considering some of the technologies available today, it is very important to weigh not just the energy savings, but also the cost of manufacturing these devices.
Heating and Cooling
In the home, there are usually few appliances that are as inefficient as our heating and air systems. However, if you live in an area that gets very hot or cold, simply doing without isn’t safe, nor is it comfortable. Fortunately, there are a number of more energy efficient heating and air systems available, which can cut back on our energy use, without having to sacrifice our comfort.
One of the most exciting technologies available to help reduce energy costs is the Geothermal Heating and cooling unit. Geothermal heating and cooling uses very long tubes that extend into the Earth and actually pull heat from the ground. In the summer, the same process can be reversed, sending the heat from the house, into the ground.
Using a geothermal system, it is possible to heat a 1500 square foot house for less than a dollar a day. Of course, they are quite expensive to install and depending on the location, can require that a very deep hole is drilled. To help off set this cost, many power companies will offer incentives for installing a geothermal heating and cooling system, with some options also available from the government. While the initial cost is very high, the savings over a 10 year period could easily offset this initial investment.
Another option for those wishing to cut heating and cooling costs is the Cold-Weather Air Source Heat Pump, which uses an additional compressor that is used when the temperature drops below 30 degrees. The second compressor is necessary because a traditional heat pump does not work well when the temperature drops below freezing, so auxiliary heat must be used. Auxiliary heat, or emergency heat, is very expensive to operate, as it uses a great deal of energy.
Using a Cold-Weather Air Source Heat Pump ends up using less power than a standard heat pump would when it gets very cold. Further, when the temperature is above freezing, only one compressor is used, so the energy usage is similar to that of a traditional heating system.
Generating Your Own Power
For years, people have been putting solar panels on their home to help reduce their dependency on fossil fuels and the power company. While this can save you a great deal of money and it is even sometimes possible to sell your excess power back to the power company, the initial investment has always been quite steep.
Recently, however, the cost of solar panels has begun to drop, as new manufacturing technologies have been introduced. This, coupled with rising energy costs across the country, has made installing solar panels a much more attractive idea.
Several companies have recently developed very thin solar panels that are relatively inexpensive to manufacture, but because they rely on some semi-rare minerals, so it remains to see whether this can be used on a very large scale.
Going Green in Your Automobile
Another popular move has been to use a more energy efficient vehicle, with a number of hybrids, which are cars that use a mixture of gasoline and stored electricity, and battery powered vehicles available.
Currently, GM, Nissan, Honda, Ford, and Toyota all offer some sort of battery powered vehicle, but when considering these cars, it is important to take into account the environmental impact that manufacturing them has.
For example, the Toyota Prius uses a very expensive battery, which uses nickel that is mined in Canada, using a mining technique that is bad for the environment. Then, the nickel must be shipped across the world, converted into batteries, and subsequently shipped back over to the US. So, with all of the environmental costs associated with the manufacture of the Prius, it tends to off set the benefits of driving it.
It All Starts with You
What a lot of people don’t always realize, myself included, is that the things we do everyday can have a major impact on the environment and the future. Even if you don’t have the money to invest in something like a geothermal heating system, you can still help the environment by changing your actions.
For example, making an effort to shut off the water when you wash your teeth and shave can save a tremendous amount of water. Also, consider setting the heat to around fifty-five and putting on an extra sweater or perhaps wearing some thermal clothing, rather than cranking up the heat.
If everyone made what are essentially very small changes to their lifestyle, it would no longer be a small change and could have a tremendous impact on the World.

Cheap Solar House Fighting to Win Contest
A solar house built by a group of students from Rice University out of Houston, TX strives to be a low cost option for houses to reduce their carbon emissions while still reducing monthly energy bills. The Zerow House as it’s called is going to be part of the Solar Decathlon contest hosted by the Department of Energy.
The major accomplishment the students are trying to achieve is to build an affordable house that a normal family can afford, yet still reduce their carbon footprint. Other entrants in the contest took quite a different approach in that they built expensive homes with fancy features. Roque Sanchez, one of the students involved in the project had this to say about the Zerow House:
We’re taking a house that any family could live in and any family could afford and adding solar to it.
It’s great to see that these students took a different approach to this house than the other entrants. I hate it when winning products of contests like this are so expensive that the normal person could never afford. Being priced at just $100,000, this house could be an excellent way many Americans could build solar enabled, yet inexpensive and practical homes. After the competition is over, Rice University also plans on donating the home to a low-income family.
I wish the best of luck to this group. Lets hope this home can make a huge impact on how homes are built throughout our country regardless of whether they win the Solar Decathlon.
Finding Alternative Ways to Produce Bio-Diesel
When most people think of the junk that ends up in a landfill, it is not uncommon to think of things like old televisions or worn out sofas. However, many do not realize that Fruit and Vegetable Waste actually accounts for a large percentage of what is in our landfills.
Fruit and Vegetable waste is commonly disposed of in landfills, because this is the easiest way of dealing with it. Finding a way to recycle and reuse this type of waste is imperative to cleaning up the environment and can actually have a number of important uses. One of the most exciting uses for fruit and vegetable waste is in the creation of bio-diesel.
Advantages of Bio-Diesel
Bio-Diesel offers several very important advantages over traditional petroleum-based diesel.
One of the most exciting aspects of using bio-diesel as an alternative energy source is that it is made from renewable resources that can be grown anywhere. This means that countries will be able to grow their own diesel and will no longer be forced to rely on oil producing countries.
In addition to helping to reduce dependence on foreign oil, bio-diesel has also been shown to offer lower emissions of carbon monoxide and hydrocarbons than petroleum based products. It is also non-toxic and biodegradable, unlike petroleum based diesels.
Problems with Manufacturing Bio-Diesel
While Bio-Diesel has a great number of advantages, it has come under criticism by some because manufacturing bio-diesel could potentially divert food products, like corn, from the Worlds food supply.
Even though the validity of this argument is highly debated, it does present an interesting problem: If farmers were able to make much more money growing plants used to create bio-diesel the amount of food produced could be dramatically affected.
Overcoming the Controversies of Bio-Diesel Production
In large part, the problem of food supply versus bio-diesel manufacturing could be overcome by reusing fruit and vegetable oil. these byproducts would otherwise end up in a landfill, but can be used to produce low cost bio-diesel.
One of the most low cost means of creating bio-diesel is by using used cooking oil and in fact there are several companies in the United States that do just this. Currently, however, the collection of these types of materials is rather inadequate and mostly limited to the restaurant industry.
In order to help reduce the cost of bio-diesel and increase its production, everyone must get involved. This means collecting lard, tallow, used vegetable oils, and other potential sources of bio-diesel not only from restaurants, but also from individuals.
Aside from used cooking oils and other cooking materials, there are a number of other potential sources that could be used to make bio-diesel.
For example, when edible oils are created, such as olive oil or cooking oil, soapstock is created as a byproduct. The soapstock is often simply discarded by manufacturers, but because it contains large amounts of fatty acids, it can be used as a low cost source of bio-diesel.
Soapstock is created by industries using soybeans, hazelnuts, olives, coconuts, sunflowers, and many other types of fruits and vegetables. There are many industries all over the world that end up with soapstock as a byproduct of production.
Creating a Greener Tomorrow
Using Bio-Diesel could not only help reduce green house gases, lower fuel costs, and reduce dependency on foreign oil, but it could also help us make better use of our landfills.
Every year, millions of tons of fruit and vegetable waste ends up in our landfills, which could have otherwise been used to create bio-diesel. This not only helps create low cost bio-diesel, but also allows us to avoid taking food off of peoples plates in an effort to manufacture bio-diesel.
