The Problem With Clean Coal

We know that you voted for Earth on Saturday 28 March and turned off your lights. We enjoyed the hour playing cards by candle light and of course we happily survived, although there may be some candle wax on the cards.

Earth Hour was a great opportunity to show our concern over global warming and to get those billion votes that they are hoping to take to the Global Climate Change Conference in Copenhagen 2009. Remember though that during that hour we also did not need much electricity in our homes or workplaces and therefore we were able to burn less fossil fuel and reduce our CO2 emissions.

Assuming the Earth Hour goal was reached and 1 billion people around the world turned off their lights for the full hour we can estimate that about 450 million pounds of carbon dioxide were kept out of the atmosphere, which is the equivalent of taking 350 million cars off the road for that hour. This is more than the total number of registered cars in the USA.

As we thought about these savings, we started talking about clean coal. We have heard a lot about it, particularly from the energy companies. They suggest that clean coal is as viable a solution to global warming as any other natural environmental energy such as solar and wind.

After doing some research here are 7 facts about clean coal.

1. We all know that coal is a fossil fuel that is used mostly by energy and electric companies in power plants and is burnt to create steam, which turns turbines and thereby creates electricity. Burning coal releases CO2 (carbon dioxide) into our atmosphere. You can see it pouring out of a power plant smoke stack.


2. One aspect of clean coal technology is to literally wash the coal with liquid prior to burning. This removes the unwanted impurities. Wet scrubbers are also used to remove sulfur dioxide (a major cause of acid rain) by spraying the coal with limestone and water.


3. Clean coal technologies also use low nitrogen oxide burners and gassification which convert the coal into a gas to burn. This is said to reduce the amount of coal burnt.


4. Any method used to clean coal will still result in CO2 emissions which will then need to be stored.


5. Carbon Dioxide capture and storage is the technology that proponents of clean coal seem to be most enthusiastic about. They suggest that CO2 emissions can be captured and kept out of the atmosphere . The captured CO2 needs to be collected in secure containers. The CO2 is then stored in 2 possible ways. Either under the ground by injecting the CO2 into depleted oil or gas fields and seams, or injecting liquid CO2 into the ocean 500 to 3000 meters deep.


6. Storage methods (underground or ocean) must be able to contain the CO2 until peak emissions subside. This will take hundreds of years.


7. The environmental effects of all the forms of storage are largely unknown. By injecting CO2 into the earth we may cause changes in the soil and pressure under the earth, and by injecting liquid CO2 into our Oceans we could damage marine life. Any form of storage will need to be carefully prepared and monitored.

Now that we have some facts, we are not convinced. With clean coal technology, we are taking the coal burning, CO2 emissions, problem and shoving it under the bed so that we can ignore it. Global warming is not "somebody elses problem" . We need to step up now and change the way we create and use energy. Drop the idea of clean coal technology and rather spend that research money on solar and wind power technology. Forget about capturing and storing CO2 and fund research into battery technology to store the natural energy sources that we have available.

Of course, you know that you can do your part too. Reduce your waste, Recycle whatever you can and Reuse as much as you can.

We still have a long way to go. I met with a friend to catch up on Thursday, at a local coffee shop. The coffee shop was full, with a line out the door, as it usually is, but unfortunately I was the only customer using my own mug. Everyone else was using a paper cup and all of them had plastic lids. There is an easy solution to this waste. If you do not have a mug then get one at http://www.gogreenmug.com/ and always remember to bring it with you to coffee shops.

Have a great week and reduce your waste.

10 Ways to Keep our Oceans Clean

Last week we mentioned that we would be taking part in the Rockwater race on March 21, 2009. This is an annual race from mountain to ocean to raise awareness about the watershed organized by Surfrider Newport Beach Chapter. We want to thank Surfrider Newport Beach, particularly Robert and Robyn, for organizing this event and for much of the information given below.

A watershed is any river, gully, canyon or pathway that drains to the ocean. Watersheds are everywhere and anything on land can find its way to the ocean via a watershed. This means that if you throw something on the ground it may eventually end up in the ocean. Drop a cigarette butt or plastic fork, and it will end up in the ocean, on our beaches, or in the stomach of a fish, sea bird or other marine animal.

It's up to you to make the right choices and protect our watersheds, oceans, beaches and marine life. Here are 10 ways you can help:

1. Always pick up your pet's waste.
2. Rake up and discard yard clippings. Do not let them get washed away with the next rains.
3. Always dispose of your cigarette butts properly.
4. Do not use a hose to water down your driveway. This wastes a lot of water and also drains the oil and other pollutants from our cars into the watershed. Use a broom instead.
5. Plant native and if necessary drought resistant plants.
6. Always dispose of motor oil properly at an approved collection and recycling facility.
7. Join in at beach clean ups or pick up trash whenever you can and dispose of it properly.
8. Excess fertilizer is often washed away into the watershed with watering or rain. Reduce the amount of fertilizer you use.
9. Reduce the amount of single-use plastic. Use reusable shopping bags for your groceries. Do not buy bottled water.
10. Get a personalized travel mug and remember to bring it with you whenever you visit a coffee shop. Do not use a disposable coffee cup, plastic coffee cup lid or cardboard sleeve. This is all waste!

Now that you know what to do to protect the watershed, here are some pics of the Rockwater 2009 race and our GoGreenMug team. The race is a 28.8 mile run/walk/bike/skateboard down the Santa Ana River from the trail head at the border of Orange County and Riverside to the Ocean in Huntington Beach. Our team consisted of Sam, Scott, Jay, Sally, Jennie, Melanie, Sarah, Sean, Dennis, and Dudley; we covered the full 28.8 miles in a little more than 4 hours 10 minutes. Congratulations to the team and to the other teams who competed.

Next year we will be back to race again. Why don't you plan to put a team together to challenge us?

Have a great week and reduce the waste.

Storing Solar, Wind and Wave Power

We have been hearing about the benefits and potential revolution that will come about when we commit to using Solar, Wind, Wave and other sustainable natural energies. We have heard how we will be able to give up on our fossil fuel habit, reduce our carbon emissions and hopefully slow down or reverse the effects of global warming.

We, of course, are big supporters of these sustainable energy sources and are excitedly anticipating some big changes now that President Obama has made environmental sources of energy an integral part of the 2009 Economic Stimulus Package and his federal budget. For now, although we know of a few homes and companies that use solar energy or wind turbines for power, we are not quite in a position that all of us can swear off those fossil fuels.

The problem is storage. Electricity cannot be stored, it can only be transformed into a different type of energy. Solar, wind, and other natural environmentally generated sources of energy are not consistent. The Sun does not always shine all day and never at night, the wind does not blow at a high enough speed all day or night either. This would mean that we may encounter electricity fluctuations as the sun goes behind a cloud or the wind dies down. Therefore, this type of energy needs to be stored before it is transformed into electricity that must be delivered. Fossil fuels such as coal and oil have that storage advantage. The coal or oil can be kept in its natural state before being burned to create the electricity.

There are a few costly ways in which Solar, Wind and other such energies can be stored - large batteries, fuel cells and heat storage. Batteries are familiar to all of us. We all know that the larger the battery, the more power it can store but this also makes it more expensive. In fact, battery technology really has not advanced much since it was invented, mostly because fossil fuels became much cheaper to use. Electric cars in particular have struggled because the cost of the battery is high and it takes a long time to charge and delivers limited mileage. This makes it almost impossible for the electric car to compete against a gas engine that can offer longer mileage and be filled up in minutes.

The other methods of energy storage may work out a lot better. Heat storage makes a lot of sense for Solar energy. The sun can heat a pipe full of water and create steam which is then much easier to store before it is converted into electricity.

President Obama's plans give encouragement to all forms of energy storage. He has even budgeted specifically for scientific research into battery technology. Once specific technologies become essential and funded, we have seen how quickly they can develop. Media (movies, photographs..) storage has encouraged hard drive manufacturers' to quickly increase hard disk storage space and retrieval speeds. Every year, larger and larger storage disks are built, while the size of the drive and the costs remain the same, or in some cases decrease.

Energy storage has also become an essential technology as we try to move away from using fossil fuels, and therefore we hope to see the same exponential technological developments and cost effectiveness here that we have seen in other technological fields.

Next weekend (Saturday) the Go Green Mug team http://www.gogreenmug.com/ and friends will be competing in the 2ND Annual Rockwater event hosted by Surfrider Newport Beach. The event is planned to raise awareness of the water shed. The water shed is the path water takes from our streets and gutters to the ocean outlet. Anything we throw out on the streets will therefore end up in the ocean. We will talk more about the Rockwater race in next week's blog. But if you want to come out and support us we will be running, walking, biking, and skateboarding from the Riverside/Orange county county line to the the Santa Ana river mouth at the border of Huntington Beach and Newport Beach.

We have not reported on any of our coffee shop visits for a few weeks now, because we think you may be bored hearing about our adventures. So why don't you let us know about your coffee shop visit and what discount they gave you for bringing in a mug. We will send a free GoGreenMug T-shirt for the best message, with a photograph, that we receive. We will publish the photograph and details in the next blog. Send your message to support@gogreenmug.com.

Have a great week and remember to reduce your waste and use your reusable mug.

Buying an environmentally clean car

The economic meltdown is causing serious difficulties for most Americans. With our investments and retirement accounts decked out in a very un-festive red, most of us cut back on our spending and reign in our shopping sprees and regular restaurant visits. Of course we could never give up a regular latte, it is the only way to start and end the work day.

According to many knowledgeable sources though, now is the time to invest. Warren Buffet (investing guru of Berkshire Hathaway) is buying shares, home prices are depressed and interest rates are low and car dealerships have great deals.

Maybe now is the right time for us to get a new fuel efficient car. Fuel efficiency is not the only criteria for a cleaner vehicle though, but for most of us finding out what is important and how a car rates environmentally is difficult.

A new law took effect on January 1st 2009 in which all new vehicles manufactured after the 01/01/2009 and sold in California must display an Environmental Performance label. This label shows 2 scores from 1-10. A smog score and a global warming score. The higher the score the cleaner the vehicle.

The Global Warming score is calculated on the greenhouse gas emissions, based on a CO2 equivalent grams per mile. The Smog score calculates the pollutant elements from the vehicle which include non-methane organic gases and nitrogen oxides. These scores are also calculated relative to other vehicles within the same model year. So think of these scores as a sliding scale test.

Battery Electric cars of course get the best scores as well as requiring zero fuel and score 10 for both the smog and global warming. The average new car sold in California has a score of 5 for both. You can get more information on the Environmental Performance label at http://www.driveclean.ca.gov/ep_label.php

California Governor, Arnold Schwarzenegger has been a strong advocate of raising emissions and fuel efficiency standards in California for some time and now President Obama has backed California's strict policies. California wants automakers to build cars that can get an average of 40 miles per gallon by 2020, while federal requirements are asking for 35 miles per gallon.

So there are a few ways we can evaluate the environmental effect of the new car we want to buy. We will look out for the Environmental Performance label and will aim to get a car with great smog and global warming scores. We will look at fuel economy and try to match or beat California's 2020 efficiency standard of 40 mpg. Finally we will make sure we have a cup holder for a GoGreenMug.

Speaking of mugs, remember to let us know about the coffee shops you visit and the discounts they offer you for bringing in your own mug. If you have not done so already also sign up to our cause on Facebook http://apps.facebook.com/causes/196342?m=fa5edc14&recruiter_id=35111682 so that we can build a community and put some pressure on the large chain coffee shops to offer better incentives for using a reusable mug.

Butts on our Beaches

Does anyone really care to see your butts on our beaches?

We are of course referring to cigarette butts. This Saturday we once again joined Surfrider Newport Beach Chapter at their regular Huntington beach clean up ( 4Th Saturday morning of every month from 8-12). We picked up many polystyrene coffee cups and broken plastic lids, just as we did last month. This month however we were made aware of the literally thousands of cigarette butts on the beach. So many that we could hardly make a dent ourselves in an hour picking them up.

Many of the beaches in California are designated Smoke-Free beaches. You can find a list of all smoke-free beaches on the Earth Resources Foundation Website. Huntington Beach (the site of the beach clean up) is on this list and we did not expect to find all these butts. Of course recent rains in Southern California have meant that our streets and gutters have been cleared out and the water has flowed down to the ocean via the watershed, bringing with it the disposed of butts and much more.

Most cigarette butts are made from cellulose acetate and are not biodegradable, only breaking apart over a long period of time, depending on conditions. This time frame can be up to 15 years. The butts therefore cause an unsightly environmental problem for many years before they break up.

The butts are also the filters for the cigarettes themselves and therefore contain the left over chemicals from the cigarette. Once they come into contact with water, the butts begin leaching these chemicals, which include cadmium, lead, formaldehyde and arsenic into the water. The butts make their way down through the watershed and end up polluting our oceans and inside the intestines and stomachs of fish, whales, dolphins, birds and the other numerous marine animals.

If you are a smoker, understand that your cigarette butts do not biodegrade and only break apart over a long period of time. They will cause numerous environmental problems. So hold on to your butts. Instead of throwing your butt out on the street or into the gutter, pick up a BUTTsOUT personal ashtray, check out http://www.buttsout.net/buttsout , or you can get them at one of the Surfrider beach cleanups.

For us non smokers, let your smoking friends know that their butts end up on our beaches and tell them what they can do about it. Join in at beach cleanups and don't be afraid to pick up the butts. At most beach cleanups gloves are supplied, so there is no need to touch them with your hands.

One way you can help reduce this type of waste on the beaches is to send a message to your State Assemblyperson and Senator through Surfrider Foundation's Action Network: http://actionnetwork.org/campaign/hotyb?rk=D7s41uFqBOJeE

Last week Dudley and Melanie were on the Island of Tonga which is in the South Pacific. This is a small country made up of many coral islands. There are no rivers or lakes on the main island of Tongatapu and the only fresh water is rain water, which is collected and stored. On small islands such as these sustainability is very important to a healthy human population. All items must be reused as much as possible. While on the island we visited a local coffee shop to sample the Tongan brew. There are no disposable coffee cups sold here, so we happily enjoyed our drinks in the glass mugs they provided.

Of course there is no reason why we as Americans and Canadians cannot do the same as the Tongans and reuse our coffee mugs and many other things too. Sustainability is important for all countries. We all need to reduce our impact on the environment in whatever way we can.

Start with your coffee mug. Remember to always bring your own when you visit a coffee shop. If you would like to create a personalized coffee mug, you can go to http://www.gogreenmug.com/ and pick one up there. And if you enjoy a smoke with your cup of coffee, remember to hold onto your butts when you are done with the cigarette.

Have a great week.
