How Solar Garden Lights Work

How Solar Works

The cells in the solar light fixtures collect solar energy (sunlight) and convert the solar energy into electricity. This natural electricity recharges a built in Ni-Cad battery in the solar lights. Depending on the amount of sunlight that the solar panels receive will determine how much energy gets stored in the battery and how much solar light will be produced. A photo-cell sensor or photoresistor, detects when it is getting dark, automatically turning on the solar light.

Solar light operating times will vary by location and weather patterns.

Plastic Water Bottles and the Environment

By now everyone should know that the PET (polyethylene terephthalate) plastic water bottles that you find in grocery stores and gas stations are the worst kind of water bottle, for both you and the environment. Studies have shown that after repeated use, these plastics can leach carcinogens. Even the plastic used in baby bottles and water bottles often used by althetes are know to release carcinogens that are harmful to our health.

Everyday millions of plastic bottles and containers are thrown in the trash and make their way to our landfills. Almost 90 percent of water bottles are not recycled and end up in landfills where it takes thousands of years to decompose. To see just how ridiculous the bottled water industry is watch this short 2 minute hilarious video clip.

Now what can we do? One option is to buy aluminum water bottles (sold at any sports store and online at Reusable Bags). These save you money and the environment and do not leach BPA. But the best option to get your water on the go is to use stainless steel reusable bottles. Again these can be found at Target, Sports Chalet, and online at Reusable Bags.

With just a little bit of effort and money up front, you can save the planet from numerous plastic water bottles not making it to the recycling center and ending up in our landfills, or worse our rivers and oceans.

Essentials of Solar Power

Here is a compliation of interesting articles and videos on solar power. There are so many sources out there, if you know of another good video or short article, let me know.

How Solar Works: Video - 1 minute
The U.S. Department of Energy has a great one minute video that shows how solar cells covert sunlight into electricity.

This video is an easy to understand lesson on how solar panels are made and assembled.

How Solar Water Heating Works: Article – 1 page
This is a great article on how a solar water heating system works. The U.S. Department of Energy says that one residential solar water-heating system can reduce the energy used to heat water by about two thirds. I know that this is no small amount of savings on an electricity bill, but can you imagine the impact this has on the environment. Seems like a very economical and efficient way to save money and the environment.

How to get Free Solar Panels – 1 page
You want cheap or free solar panels, with only the cost to install them on your home. Michelle Bennett from cleantechnica.com came up with a great idea, recycle and reuse “damaged” commercial solar panels that are just fine for a residential home. To find out more check out the article at http://cleantechnica.com/2008/02/07/how-to-cheap-or-free-solar-panels/

Make sure you don’t go and steal these solar panels, as apparently that is the new crime wave of the future. Check out this article, some people are just pathetic.

Awesome Invention: Article – 1 page
Solar paneled purses. What a brilliant idea! I just read a story by Rachel Aviv on the New York Times.com site. It is about an Iowa State University doctoral student named Joe Hynek who invented a handbag lined with solar panels. It also includes a lightweight battery to store enough energy to power a cell phone, ipod and even a camera. Now why didn't I think of that.

Tax Incentives and Rebates
One always hears about tax incentives and rebates for using renewable energy sources, whether it is solar power panels, buying energy efficient appliances, or possibly buying solar garden lights. It is my opinion that those incentives (particularly federal incentives) will increase significantly in the next year or two. To keep updated on your state, city, and county’s incentive programs, the DISRE is great comprehensive, searchable database http://www.dsireusa.org/

Next week, information about using nanotechonology to increase the efficiency (and of course cost) of solar panels, replacing silicon solar cell techonology with plastic solar cells, where scientists are in the designs, and what it could lead to.

Cremation and the Environment

I know that death and funerals are a subject of “taboo” in our society and many people avoid discussing them, but this topic might be of interest to some. The other day I was at the coffee shop having a normal conversation with my friend Mark, about the environment and “green” lifestyles and choices, when out of the blue he said that it is better for the environment to get cremated as opposed to buried in the ground. So of course I asked, “Is cremation really good for the earth? What about the smoke and the carbon dioxide and all the gases used in the furnace?” After a little research I was surprised to find out that there is a lot of debate about whether cremation is more ecologically friendly than traditional burial. When all the information and facts are added together, I think that Mark was right. Whatever choice you make, make sure it is what the deceased wanted and that it ends up being a beautiful celebration of life.

Pollution from Traditional Burials
Traditional burial spots take up a huge amount of space (many areas in Europe and Japan have simply run out of space to bury the deceased and it is really hard and very expensive to find traditional funeral plots). In addition the fluids used to embalm a body contain arsenic, mercury, and formaldehyde, which are all toxic. Casket manufactures are listed on the EPA’s top 50 hazardous waste generators because they use chemicals such as methyl and xylene to make a protective layer on the casket.

Due to the need to upkeep and preserve the burial grounds, traditional burial is a more labor and resource intensive process. One also has to consider the exhaust used by the truck that digs the grave, the mower used to upkeep the grounds, the chemicals and exhaust released from the equipment used to make the caskets, etc.

Most of the issues discussed above are issues that we (society), can and will find ways to improve the process and make traditional burial more environmentally friendly. For example, many people are choosing to use more environmentally friendly caskets. Others are refraining from embalming their loved ones and having the burial shortly after death. The one problem that cannot be fixed (except if you choose cremation) is the amount of earth and ground used in burial plots.

Pollution from Cremation
Cremation relies on finite fossil fuel reserves and creates emissions that pollute the environment. Cremation releases nitrogen oxides, carbon monoxide and dioxide, hydrochloric acid (HF), hydrofluoric acid (HCL), sulfur dioxide, particulate matter, mercury and other heavy metals into our atmosphere. As with most modern technology, natural-gas equipment used to cremate a body is becoming more efficient and burning cleaner, but not every place uses these more eco-friendly chambers.

Most of the air pollution is caused by the burning of the casket, which more times than not contain high quantities of toxic glues and plastic handles. Just like with traditional burials, a casket made from all natural materials (with removable handles) is certainly a good environmental choice and can dramatically reduce the amount of air emissions produced. SOME crematorium manufactures have built computerized control systems that regulate the exhaust systems to reduce the amount of air pollution. Also SOME crematoria’s remove all plastic handles and fittings from a coffin before cremation.

It is certainly good that some of these crematoria's are taking the right step in protecting (or at least not damaging) the environment, however it is still not the norm. Even when factoring in the air pollution released during cremation many "green" experts agree that cremation is better for the environment than traditional burials.

An Economic Perspective
In most cases cremation costs significantly less than a traditional burial service. It is even less expensive if the cremation occurs shortly after death without any sort of formal services. While traditional burials are still the most popular, the trend towards cremation is increasing. One reason may be due to the economic crisis we face and families who are affected by it are looking at cremation as a less costly way to honor their loved ones. This might be a twisted look at “saving money and the environment” but it is the truth. Whatever the choice, make sure it is what the deceased wanted and that it ends up being a beautiful celebration of their life.

What to do with your remains
This is an interesting thing to think about if you want to be cremated. I have not done all the research to verify that it helps the environment but it is a great plan if it does.

Memorial reefs, also know as “reef balls.” There is a company (Eternal Reefs) that has developed a process that mixes the cremated remains with liquid concrete and pours it into a mold to create a ball. The reef ball (along with many other reef balls) creates an artificial reef that provides health and home for sea life.

It only takes a few months for the artificial reef to look like a natural reef and only a few weeks before life begins to flourish. They provide you with the exact location of where the reef is (latitude and longitude coordinates) so you can visit by boat and even scuba dive to your loved ones memorial.

Memorial reef balls cost between $2,495 and $6,495, which is not including the cost of cremation.

Solar Energy Facts

Solar energy is a general term used for any method or technique used to obtain and store energy from the sun. Solar technology’s history goes back to 7th century B.C using glass and mirrors to light fires (View an excellent historical timeline for more information). Solar energy can be used to heat swimming pools, run small appliances, power cars, cooking food, and many other practical uses. Solar energy is becoming more and more popular as well as more efficient and economical.

Interesting facts about Solar Energy

* It takes about 8 minutes for the sun to reach the earth’s surface once it has been released from the core.

* The sun’s energy is free and will not be depleted for a long, long time. The sun will start to collapse and eventually burnout in about 5 billion years.

* Albert Einstein was awarded the Nobel Prize in 1921 for his discovery of the law of photoelectric effect – a phenomenon where electrons are emitted from a surface when light shines on it. His studies are the foundational building block for solar cells, imaging, telecommunication networks, and so much more.

* The Mojave Desert in North America has the world’s largest solar power plant, containing 1000 acres of solar reflectors.

* If we covered 15% of the Sahara desert with solar cells, it would generate more energy than the entire world consumes, including fossil and renewable energy sources.

* In 1990, a solar powered airplane flew across the U.S. with no fuel, setting a world record.

Solar Panels for your Home!

A 1-kilowatt home solar system takes 1 or 2 days to install. The cost of a home solar system varies but is somewhere around $10,000. Prices have dropped dramatically and are continuing to go down every month (solar technology is getting more efficient). Depending on the incentives offered by federal, state, and local governments, solar systems can be a great short term and long term investment. Solar energy systems require very little maintenance and will last for a very long time.
This same 1-kilowatt home solar system will replace approximately 170 pounds of dirty coal from being burned, it will save 105 gallons of water from being consumed and prevent 300 pounds of COS from being released into the atmosphere.
While there continue to be disadvantages to installing solar panels, the technology is improving every day and will very soon be in many different neighborhoods and business communities.

If you are not ready to get solar panels on your home, there are many options for reducing your consumtion of electricity. Visit greengardenecology.com for solar lights for your home and garden.

Green Machines and Gas Saving Tips

Today most consumers are staying away from the gas-guzzling SUV’s and are buying more economical cars. Not only does this help people’s pocket books (in the short run as far as the vehicles price, and in the long run savings on gas), it is much better for the environment. While car manufactures are designing and creating the next generation hybrid and electric vehicles, consumers can save money and the environment today with 9 silly-smart choices.

1. Change your air filter: A clean air filter can improve gas mileage up to 10%. It costs about $5 for you to do it yourself or $15 at your local mechanics (do not pay anymore).
2. Check your Alignment: It is common knowledge that poor alignment reduces the life span of a tire but did you know that poor alignment forces your engine to work harder, reducing fuel efficeicent up to 10%. It costs between $40 and $90 to get your tires aligned. Also keep you tires inflated properly.
3. Get a Tune Up: Seems simple huh. A well oiled engine can improve gas mileage by up to 4%
4. Got A Gas Cap? Check to see that your gas cap is not broken or missing. A car that is missing its gas cap not only releses harmful toxins to the environment, but you are loosing gas mileage efficency as well.
5. Slow Down and Drive Smoothly: Fuel consumption increases by 7% as speed reduces by 5 miles. Try to accelerate and decelerate more smoothly. This can help your gas mileage by 33% oh the highway and 5% around town.
6. Don’t Ride the Brakes: Not only do you wear the breaks out but it increases the amount of gas your vehicle uses by as much as 35%.
7. Decrease Your Load: Remove unnecessary items from your car and trunk.
8. Don’t Idle: When your car is idling, not only are you wasting gas but your causing pollution. Turn off your engine if you are stopped for more than 30 seconds. Unless you have a very old car, you do not have to “warm up” your car before driving.
9. Use Your Cruise Control: Your vehicle performs most efficiently when driven at a constant rate. Save money on unwanted speeding tickets, increase your cars fuel consumption and save the environment
