Green Printing - Recyled Paper vs. E-Paper 19 Oct 2008 12:56 PM (16 years ago)

One kind of industry rarely discussed among environmental movements is the paper business.

It seems like such an obvious industry – paper is made from trees, after all.

The consensus seems to be that there are two options facing the future of paper: make recycled paper or make it electronic. Recycled paper, obviously, is paper made from paper that has already been used and recycled. This can be extremely efficient; the first recorded instance of making recycled paper in the United States was 1690 and has only been improved since then. Most paper today is actually used for packaging, so using recycled paper only makes more sense.
Electronic paper (e-paper) is a little more interesting. This has been most visible the past few years in e-book readers (notably the Amazon Kindle) and electronic billboards. The debate is still up on whether or not it is green. It saves trees – but what about the chemicals? For example, most plastic used in computers is made from petroleum. That leaves me at least to conclude that recycled paper is much more efficient than e-paper.

How can recycled paper be made more efficient?
• Paper waste must be recycled
• Printing facilities can be closer to where you live (this one’s arguable; building another facility arguably creates more emissions that it saves – it depends)
• Use soy based inks rather than petroleum based ones

One printing company I’ve found to have truly green printing is PsPrint. It does everything I’ve bulleted above.

Of course there are plenty of other green companies, but none are as local for me as PsPrint. It does brochure printing and everything, which is especially good for the business I’m in. They are also involved with or members of several eco-friendly organizations! :)

Accidentally Discovered Material, Black Silicon, Twice as Efficient As Regular Silicon 14 Oct 2008 5:05 PM (16 years ago)

Harvard (TGW) – SiOnyx is using a material, “black silicon”, Harvard scientists accidentally discovered almost 10 years ago that is 100 to 500 times more sensitive to light than traditional silicon.

The silicon is produced by placing ordinary silicon into a vacuum chamber together with sulfur hexafluoride gas and exposing it to ultra-intense laser pulses equivalent to the collective strength of the total sunlight hitting Earth concentrated on a surface area that's about the size of a human fingernail.

The treated silicon can absorb twice as much visible light as regular silicon and unlike standard silicon is sensitive to invisible infrared light. It can absorb approximately 96 to 98 percent of visible light.

SiOnyx, a three year old startup with $11 million in the bank, has licensed the material.

Black silicon could radically change the solar industry. Furthermore, black silicon can be manufactured using the same equipment used today.

10 Northeast States to Participate in First U.S. Carbon Auction This Thursday as Part of Cap and Trade Program (RGGI) 22 Sep 2008 5:09 PM (16 years ago)

Northeast (TGW) – A group of 10 northeastern states will conduct the first carbon action in the United States, in an attempt to reduce humanity’s contribution to global warming.

The Regional Greenhouse Gas Initiative (RGGI) will be selling carbon credits Thursday in the first of a series of quarterly online auctions.

The cap and trade aims to steady carbon emissions by 2014. This would be followed by a 10% reduction in emissions between 2015 and 2020.

Connecticut, Delaware, Maine, Maryland, Massachusetts, New Jersey, New Hampshire, New York, Rhode Island, and Vermont are participating in the auction. Pennsylvania, Washington D.C., and Quebec in Canada are participating as observers.

The starting minimum will be $1.86 per ton of carbon dioxide.

RGGI, at least for now, only caps the emissions of power plants.

How are the Candidates Going to Clean America? 19 Sep 2008 6:11 PM (16 years ago)

The method in which America creates energy has been a hot topic during the 2008 presidential election. For most, a primary concern deals with how we can keep prices down at the pump while eliminating our need for foreign oil. This desire has lead to the “drill here, drill now” crowd calling for domestic offshore drilling (among other things). While everyone agrees that energy independent principles are vital to revving up the American economy, there are big differences in how to accomplish this task. Notably, when it comes to the energy resources and environmental protection standards, there are fundamental differences in Barack Obama’s and John McCain’s interests. Additionally, when it comes to bills in congress addressing consumer protection, manufacturing standards, and other topics not talked about enough, the future will heavily depend upon which candidate prevails. The following include a few you may not have known about, and some you may have, but they are all liable to affect the lives of everyday Americans.

One fact to note when looking for the candidates policies on their respective websites is that Barack Obama has a category named “Energy and Environment” under the “Issues” section. On the other hand, John McCain has “American Energy” and “Climate Change” listed as separate categories under the “Issues” section. This seemingly subtle difference represents some conflicting policies between the two candidates. While McCain believes in global warming, he is resistant to associate the call for more oil with his global warming concerns because supporting the two issues is a sheer contradiction. In sum, Obama wants to rid our dependence on all oil (not just foreign) and McCain wants to use every available resource needed to end our dependence on foreign oil.

McCain calls his energy plan “The Lexington Project,” which is an all of the above energy solution according to his website. Included is expansion of domestic oil and natural oil exploration, tax credits for automakers and consumers who buy cars with low carbon emissions, $2 billion annually reserved for clean coal technology, 45 new nuclear power plants and he will “encourage” the market for alternative fuels such as wind, hydro, and solar power. He has greenhouse gas emissions targets listed in the climate change section that includes dropping it 15 percent below 2005 levels by 2020 and 66 percent below 2005 levels by 2050.

Obama calls his plan “comprehensive” and puts added emphasis on new forms of energy. He wants to provide $1,000 to American families through a windfall profits tax, calling it an “Emergency Energy Rebate.” He will invest $150 billion over the next 10 years to build a clean energy future, and in that same allotted time, rid American dependency of foreign oil. He wants to put one million plug-in hybrid cars on the road by 2015 and ensure 10 percent of our electricity comes from renewable sources by 2012 and 25 percent by 2025. In addition, Obama wants to implement an economy –wide cap-and-trade program to reduce greenhouse gas emissions 80 percent by 2050.

Interestingly, by 2050 many of those reading this article still won’t be as old as John McCain is now. Moving on, there are other issues that you may not hear about quite as much.

The use of asbestos in products and the manufacturing industry could come to a close in 2009. Senator Patty Murray introduced the “Ban Asbestos in America Act” that has been introduced and passed by the entire U.S. Senate. However, the bill does contain a harmful pro-industry amendment eliminating coverage for workers exposed to products containing one percent or less of asbestos. CWA and the AFL-CIO will work to have this language omitted in the final Senate-House legislation.

Congresswoman Betty McCollum has introduced the “Bruce Vento Asbestos and Prevent Mesothelioma Act of 2008.” This legislation is not expected to be passed by the full house during 2008, so this is basically groundwork in order to get the bill passed in 2009. Right now there are now mesothelioma treatments that result in a cure.

Another bill is the “Chemical Facility Anti-Terrorism Act of 2008.” These are all supported by the Blue-Green Labor/Environmental Coalition.

With Barack Obama as president and a Congress dominated by democrats, the above legislation should all pass. With John McCain as president, the bills could be vetoed.

In paying for all of these plans, Barack Obama pledges to raise taxes on the wealthiest Americans (annual income of $250,000) and raise taxes on oil companies. While John McCain will actually lower taxes for oil companies, he pledges to cut small business taxes and promote fiscal responsibility within the government. He says that with bi-partisan efforts, he can bring the budget to balance by 2013. Until then, expect a dirty fight in efforts toward a cleaner America.

65 MPG Ford Won't be Available in the U.S. 9 Sep 2008 3:43 PM (16 years ago)

Not the U.S. (TGW) – Ford Motor’s 65 mpg diesel Fiesta ECOnetic will not be available for sale in the United States, Ford has announced.

The five-seater will only be sold in Europe because the vehicle runs only on diesel. In Europe half of cars run on diesel; only 3% of American owned cars do.

Diesel fuel is now as clean as or cleaner than gasoline and is at least 30% more efficient.

The Fiesta would be $25,700 not including a $1,300 tax deductible available for diesel car owners.

Ford will be making a gas powered Fiesta. (Yes, that sentence sounds a little strange)

Google Files Patent for Wave-Powered Floating Data Centers 8 Sep 2008 2:57 PM (16 years ago)

Google HQ (TGW) – Google has filed a patent for a system of floating data centers powered by the waves beneath it.

All though the patent was filed over a year ago, the patent was only recently found.

According to the patent, Google wanted to move data centers closer to users, but power generation would be too expensive to make that feasible. To solve that problem, Google came up with this idea: floating data centers holding standard shipping containers housing computers powered by wave-power generators and wind turbines.

Google engineers calculated generators spread over about half of a square mile could produce 30 megawatts of electricity, enough to operate a single system.

A crew and operating staff would live aboard in living quarters, with a helipad for transportation.

Polar Bears Going Green Too! 7 Sep 2008 5:46 AM (16 years ago)

This little big green polar bear at the Higashiyama Zoo and Botanical Gardens in Japan got some interesting stares from visitors this weekend. The greenness was caused by algae stick to the bears fur.

High temperatures in July and August and less-frequent water changes because of the zoo's conservation efforts have caused an algae growth in the bear pond and safety moat.

Honda Unveils Cheap Insight Hybrid 4 Sep 2008 4:09 PM (16 years ago)

Honda HQ (TGW) - Honda today unveiled the hybrid Insight, said it will be shown at the 2008 Paris Motor Show, and announced that it will only be sold as a hybrid.

The only car that is on sale currently only as a hybrid is the Toyota Prius.

Giant Floating Generators to Provide Energy and Food to Japan 3 Sep 2008 12:31 PM (16 years ago)

Japan (TGW) – Scientists at Kyushu University in Japan have come up with a solution to Japan’s energy and food problems: massive floating generators.

200,000 hexagonal photovoltaic generators and wind turbines on the floating “eco-rigs”, which measure 1.2 miles by 0.5 miles, would produce about 300 megawatt hours of power.

Some of that power would be lost in transporting the power back to shore, but by strapping three of the rigs together, the effect would be the same as a standard nuclear power plant.

Some of the energy from the solar cells and wind generators would be diverted to power LEDs on the bottom of the rigs.

The lights would turn the platform into a nursery for a specially selected type of seaweed that absorbs carbon dioxide and feeds fish and plankton.

The eco-rigs will be unmanned and automatic.

The first rigs are expected to be ready three years from now.

Triple Helix Vertical Home Wind Turbine Generates 6 Kilowatts 2 Sep 2008 5:39 PM (16 years ago)

Your roof (TGW) - Quiet Revolution, a London based small wind turbine maker, has raised $12.5 million in funding for its 6 kilowatt triple helix wind turbine, the ‘qr5’.

The qr5 uses three S-shaped blades which are designed to work in urban environments where wind speeds are lower and change frequently.

The turbine is just 15 feet high and 9 feet wide. 30 have already been sold and 45 are in the process of being installed.


However, the turbine isn’t cheap at a nice £25,000, plus installation costs of £3,000 to £6,000 per turbine, turbine controls that cost £4,600, and the cost of the mast, £2,950 - £5,150

The company is working on a smaller qr2.5 which would be 7.5 feet high and would generate 3000 to 4500 kwh as well as a qr12 would be 36 feet high and would generate 45,000 and 55,000kWh on a decent wind site.

Quiet Revolution is targeting schools and businesses for its products.

10 Things You Can Start Doing Today to Minimize Global Warming 25 Aug 2008 8:21 AM (16 years ago)

This post was contributed by Heather Johnson, who writes on the subject of green shopping . She invites your feedback at heatherjohnson2323 at gmail dot com.


Global warming is an issue that affects each and every one of us in one way or another. The fact of the matter is that there is always something more we can do to decrease the amount of energy wasted and greenhouse gases produced every day. What follows is a list of some things we can start doing—today—to do our part in the fight against global warming.

1. Consider alternate sources of transportation. Instead of driving your car each day, think about using public transportation. If this is simply not feasible where you live, try walking, riding a bike, or even carpooling.

2. Monitor your energy consumption. With some household items, the power is always running, even when they appear to be off. If you’re not going to be using electronics, simply unplug them or shut off the power strip they are connected to.

3. Change out your existing light bulbs. Standard incandescent light bulbs are very wasteful and have a very limited lifespan. Start witching out your old bulbs for compact fluorescents and watch your energy bill go down.

4. Reuse and recycle your plastic bags and containers. If you are not doing this already, it is of vital importance that you begin to do this. Plastic bags (if you must take your purchases in them) can be reused for trash, or to carry lunches to and from school or work. Other plastic containers can be useful for storage or putting your leftovers in.

5. Buy recycled products whenever possible. Another thing we often forget about is that many items we buy regularly are available in recycled incarnations. Toilet paper, for example is a product that we all must use, so why not use recycled paper if it is simply going to be flushed away?

6. Look at how your purchases are packaged. Many items we buy at stores have far too much unnecessary packaging. Look for companies that package their products with Mother Earth in mind.

7. Tend your own garden. Maintaining a garden helps put more oxygen into the atmosphere, and is also a great and relaxing activity. If you have enough of a green thumb, try growing your own produce and enjoy the fruits of your labor.

8. Take your own food or drinks with you. Rather than spending money at wasteful restaurants and fast food places, take your own meals with you. It will cave you time, money, and make an indirect difference in the process.

9. Support businesses that are committed to the environment. Many businesses claim to be part of the green movement, but do your homework. Supporting local coops and business is probably far better for everyone involved. If you must support major companies, make sure you are supporting the right ones.

10. Keep your vehicle properly maintained. If you must use your vehicle every day, make sure that it is in good working order. Change your oil with synthetics, monitor your tire pressure and run your heat or air conditioning only when you really need to. Remember, every little bit helps, and if every one does a little bit to change their habits, it adds up to make one big difference.
