Responsible Choices
The choices we make and the products we buy test our commitment to maintain a healthy planet. When we burn fossil fuels—such as oil, coal, and natural gas—to run our cars and light our homes, we pump carbon dioxide (CO2) into the air. This thickens the heat-trapping blanket that surrounds the planet, causing global warming.

Choosing modern technology can reduce our use of fossil fuels and help protect the planet. These ten steps will help curb global warming, save you money, and create a safer environment for the future.

Drive Smart!
A well-tuned car with properly inflated tires burns less gasoline—cutting pollution and saving you money at the pump. If you have two cars, drive the one with better gas mileage whenever possible. Better yet, skip the drive and take public transit, walk, or bicycle when you can.

Buy Local and Organic
Did you know the average American meal travels more than 1,500 miles from the farm to your plate? Think of all the energy wasted and pollution added to the atmosphere—not to mention all the pesticides and chemicals used to grow most produce! So go to your local organic farmer to get your fruits and veggies.

Support clean, renewable energy.
Renewable energy solutions, such as wind and solar power, can reduce our reliance on coal-burning power plants, the largest source of global warming pollution in the United States. Call your local utility and sign up for renewable energy. If they don’t offer it, ask them why not?

Replace incandescent light bulbs with compact fluorescent bulbs.
Especially those that burn the longest each day. Compact fluorescents produce the same amount of light as normal bulbs, but use about a quarter of the electricity and last ten times as long. Each switch you make helps clean the air today, curb global warming, and save you money on your electricity bill.

Saving energy at home is good for the environment and for your wallet.
Start with caulking and weather-stripping on doorways and windows. Then adjust your thermostat and start saving. For each degree you lower your thermostat in the winter, you can cut your energy bills by three percent. Finally, ask your utility company to do a free energy audit of your home to show you how to save even more money.

Become a smart water consumer.
Install low-flow showerheads and faucets and you’ll use half the water without decreasing performance. Then turn your hot water heater down to 120°F and see hot-water costs go down by as much as 50 percent.

Buy energy-efficient electronics and appliances.
Replacing an old refrigerator or an air conditioner with an energy-efficient model will save you money on your electricity bill and cut global warming pollution. Look for the Energy Star label on new appliances or visit their website at www.energystar.gov to find the most energy-efficient products.

Plant a Tree, protect a forest.
Protecting forests is a big step on the road to curbing global warming. Trees “breathe in” carbon dioxide, but slash-and-burn farming practices, intensive livestock production, and logging have destroyed 90 percent of the native forests in the United States. And you can take action in your own backyard—planting shade trees around your house will absorb CO2, and slash your summer air-conditioning bills.

Reduce! Reuse! Recycle!
Producing new paper, glass, and metal products from recycled materials saves 70 to 90 percent of the energy and pollution, including CO2, that would result if the product came from virgin materials. Recycling a stack of newspapers only four feet high will save a good-sized tree. Please… buy recycled products!

Mount a local campaign against global warming.
Educate your community about how it can cut global warming pollution. Support measures at the national, state, and local level that:

• Make automobiles go further on a gallon of gas;
• Accelerate the use of clean, renewable energy sources, such as solar and wind;
• Increase energy efficiency and conservation; and
• Preserve forests around the world.

Earth Hour started in 2007 in Sydney, Australia when 2.2 million homes and businesses turned their lights off for one hour to make their stand against climate change. Only a year later and Earth Hour had become a global sustainability movement with more than 50 million people across 35 countries participating. Global landmarks such as the, Sydney Harbour Bridge, The CN Tower in Toronto, The Golden Gate Bridge in San Francisco, and Rome’s Colosseum, all stood in darkness, as symbols of hope for a cause that grows more urgent by the hour.

In March 2009, hundreds of millions of people took part in the third Earth Hour. Over 4000 cities in 88 countries officially switched off to pledge their support for the planet, making Earth Hour 2009 the world’s largest global climate change initiative.

Earth Hour 2010 takes place on Saturday 27 March at 8.30pm (local time) and is a global call to action to every individual, every business and every community throughout the world. It is a call to stand up, to take responsibility, to get involved and lead the way towards a sustainable future. Iconic buildings and landmarks from Europe to Asia to the Americas will stand in darkness. People across the world from all walks of life will turn off their lights and join together in celebration and contemplation of the one thing we all have in common – our planet. So sign up now and let’s make 2010 the biggest Earth Hour yet!.

It’s Showtime! Show the world what can be done.

Earth Hour by WWF

Earth Hour is organized by WWF. With almost 5 million supporters and a global network in over 100 countries, it’s one of the world’s largest and most respected independent conservation organizations. WWF’s mission is to stop the degradation of the Earth’s natural environment and build a future where people live in harmony with nature.

Why get involved?

Put simply, because our future depends on it!

Earth Hour has done a lot to raise awareness of climate change issues. But there’s more to it than switching off lights for one hour once a year. It’s all about giving people a voice on the future of our planet and working together to create a sustainable low carbon future for our planet.

The future can be bright

New economic modelling indicates the world has just five years to initiate a low carbon industrial revolution before runaway climate change becomes almost inevitable. But it can be done, and the long term benefits will be enormous.

So now’s the time to take a stand and give world leaders the mandate they need to make the right climate deal.

Did you know that for a family of four to fly from New York to Honolulu and back produces more carbon dioxide emissions than the average American family car does in one year. Many scientists agree that carbon offsets do not work and that they can cause more harm to the environment than any potential benefits they may have. Wouter Buytaert, a scientist at Imperial College in London specializing in environmental studies said, “Planting fast growing pine trees on grassland will help to lock up carbon in the tree, but it may also disrupt the soil and release carbon already stored in the grassland. And in some cases there can be severe negative side effects too. Extensive areas of grassland in the upper tropical Andes, South America, have already been planted with pine trees, paid for by carbon credit schemes. The pine trees guzzle water much faster than the native grass, reducing stream-flow by around 70 percent and drying up the water supply for towns and cities downstream such as Cuenca and Quito in Ecuador. “It is just a case of substituting one problem for another,” he said.

If we are ever to become a carbon nuetral world we will have to come up with some better ideas and fast to help our planet. We need to have our goal be sustainability and conservation, otherwise we will never succeed in our mission.

In response to my post regarding the banning of lightbulbs in the state of California I recieved some information from a reader that I would like to share with everyone that details the other side of the arguement.  I am always excited to hear from subscribers and value any comments and information you would like to add to the site.  The following information is from a site called CEOLAS.NET:

A Safe Product

A ban on light bulbs, as with other electrical products in current use, is strange in consumer law:
They are bans on safe products, we are not talking about banning lead paint or fireworks here.
In fact, light bulbs have been safely used for over 100 years without significant problems, unlike other lights.
The irony is that a normal ban would rather be on the main suggested replacement, compact fluorescent “energy saving” lights (CFLs), with several health and environmental concerns.

Cars give out emissions. Electrical products do not.
Banning a type of car stops emissions. Banning a type of light does not.
Cars are taxed on related carbon efficiency.
Lights -and electrical products- can be taxed on related carbon efficiency (although still wrong in principle, since energy and emission problems can and should be dealt with directly).

Old Technology – New Technology

There’s a lot of talk about old and new technology with lighting.
“Hey isn’t it great to get rid of old technology” we are told.
“Light bulbs are over 100 years old, time to get rid of them.”

The obvious counter is “if it ain’t broke – don’t fix it”.

First of all old technology means known technology means proven, reliable and, as just said, safe technology, for a product we spend half our lives using, sometimes within a few feet.

Secondly, it’s one thing to have a product fade a way from lack of consumer demand in face of a significant improvement as viewed by the people, as opposed to a ban put in place by politicians because of an improvement as they see it.

Let’s compare the light bulb with its cousin – the radio valve (tube).
Now, radio valve use faded away because everyone could see the advantages of transistors.
Did that mean banning radio valves?
No Sir, they are still around, a limited demand for a limited use, but nonetheless available for those who want them.
Yet, since they use much more energy than transistors, they could conceivably have been banned to save energy too.

Does this ring a bell?
Now, everyone is talking about how great LED lights will be. And why not – perhaps people will actually want to buy them!
You don’t have to be Einstein – or Edison – to know what that could mean. If people mostly buy LED lights, and fewer ordinary light bulbs, then energy use (supposedly) drops dramatically, and no ban is needed.
A natural market process, which nevertheless allows those who like light bulbs to continue to use them.

Notice how the opposite is of course true too:
If ordinary light bulbs remain more popular than LED or any other lighting – why ban what people obviously want to use?
Let’s expand on that….

A Popular Product

A safe product that is not popular does not need to be banned, because so few are using it anyway.

This gives us the beautiful (and typical) logic, that the more popular a product is, the more energy use it will cause, and the more politicians can wave their arms in their air and say how great they are for (supposedly) letting people save so much money, by banning a product that people obviously want to buy and use!

Unsurprisingly, the EU is at the forefront of this logic.
The word from EU officials is
“The campaigns have failed, Europeans still choose to buy these lights, legislation is the next logical step”
Instead of saying
“The campaigns have failed, Europeans still choose to buy these lights, how can we respect this strong will of the people?
Is it really necessary to ban these bulbs?”

Light bulbs are overwhelmingly popular in the EU, as elsewhere.
They are the lights that people want to buy (9 times out of 10 in the EU, according to the European Commission’s own research 2007-8, 19 out of 20 in the USA from lighting industry data in the same period).

Speaking of the USA:
Just 18% of adults think it’s the government’s job to tell Americans what kind of light bulb they use, according to a July 2009 Rasmussen Reports national telephone survey. 72% say it’s none of the government’s business, and 10% are not sure.

An “Unpopular” Product

Now, the European Commission has also relied on data from an organization called VITO.
The music was then rather different.
As the Cambridge Network science organization point out:
A study by VITO consultants showed the following breakdown of lamp use in European homes in 2007:
•  54% incandescent (down from 85% in 1995 and still decreasing)
•  18% low-voltage halogen (and increasing)
•  5% mains-voltage halogen (and growing)
•  8% linear fluorescent
•  15% CFL

What spiel did the Brusselcrats then think up?
Of course the story was then “how Europeans are taking to these lamps”, and that the “reports that they don’t like them” are “unfounded”!

The problem is, that this kind of data of course means that the supposed great savings aren’t there, and, as outlined in Old Technology – New Technology above, that a ban is again unwarranted, this time because a conversion is taking place anyway.

As the good Cambridge scientists put it:
“If we assume that all remaining filament bulbs are replaced by CFL at some point in the future (unlikely, as use of halogen bulbs is likely to increase), that these bulbs are used to the same extent as those they replace and that the energy reduction per bulb is 80%, the total reduction in EU energy use would be 0.54 x 0.8 x 0.76% = 0.33%. This figure is almost certainly an overestimate, particularly as the inefficiency of conventional bulbs generates heat which supplements other forms of heating in winter. Which begs the question: is it really worth it?”

No, scientists, it isn’t – whether the bulbs are popular or not – but try explaining that to anyone who commutes to Brussels.
Besides, if people like halogens, then that door must – and will – be shut too, as laid out in the December 2008 EU banning documentation linked above. Remember: Soviet Union, not European Union.

A Cheap Product

The assumption is that people only buy light bulbs because they are cheap.
Certainly they are cheap -no crime- but you don’t keep buying something only because it is cheap, and attractive features of light bulbs will soon be given.

Nor do you avoid buying a CFL or anything else just because it is expensive:
Otherwise no expensive alternative products anywhere would ever be bought.
In normal advertising manufacturers themselves highlight advantageous features of their products.
Think of long-lasting batteries and Energizer bunnies, think of washing up liquids that wash piles of dishes.
“Expensive to buy but last long”:
CFL/LED manufacturers wrongly rely on public campaigns and bans to make sales.
So, when politicians say “a ban is the only way” for the public to buy an expensive product that “people will find very attractive when they do buy it”, advertising by manufacturers could highlight that, and people would buy one and then buy more if they are so good, as with the other products.

That said, many households already have at least 1 CFL (the UK is typical, 1/2 of households there and in most countries have at least 1 CFL and the average UK and European household has around 2 CFLs and 20 light bulbs, Commission research).
So maybe they feel that is enough:
There is no reason just to use CFLs -or light bulbs- in a house, all lights have their own advantages and different uses (see below).
Of course, the other explanation is that maybe people simply don’t like CFLs, having tried them…
Certainly CFLs can improve, but it hardly justifies banning bulbs now, and hardly justifies it later either:
if people actually like improved CFLs or LEDs and buy them in greater numbers, there is again no need to ban ordinary light bulbs, as explained above.

A Useful Product

Light bulbs have many attractive features, apart from being cheap.

A warm bright light quality:
This is the biggest loss, in banning “incandescent” lights (=ordinary light bulbs and halogens).
For displays and in some home decorating schemes, designers use the sparkle effect that one can get with the point source incandescent lighting.
Also the beam can be focused, by lamp shades in reading lamps for example.
Small bright incandescent lights are particularly useful, since small CFL or LED lamps technically can’t be made as bright, and the bright types that can be made are particularly expensive.

New York, NY – The growing community of Battery Park City now has its own library. On March 18, The New York Public Library will open its Battery Park City branch, an environmentally friendly library which provides a wide range of services for the community. The public is invited to celebrate the branch’s opening with a morning ceremony, an architectural tour of the library, and a day of free events for the entire family. The 10,000 square-foot, two-story branch is located at 175 North End Avenue.

“The striking new environmentally friendly library in Battery Park City is sure to quickly become a beacon for the community,” said Paul LeClerc, President of the New York Public Library. “At a time when people are depending on libraries more then ever for free resources and job assistance the library is a crucial resource for the neighborhood. We are deeply grateful to our elected officials, Mayor Michael R. Bloomberg, City Council Speaker Christine C. Quinn, and City Council Member Margaret Chin for their support of the branch’s construction. We also greatly appreciate the generous private funding provided by Goldman Sachs & Co.

With light streaming through broad windows and glimpses of the Hudson River the $6.7 million Battery Park City Library provides a vibrant and welcoming atmosphere for the public. The 88th branch of the New York Public Library will anchor the bottom two floors of the city’s greenest residential high-rise to date. Designed by the architecture firm 1100 Architects, the branch includes 24,000 items, 36 public access computers, and separate reading areas for children, young adults, and adults. A multipurpose programming room on the second floor is also featured, as well as two self-checkout machines for public use. The Library was constructed with a focus on environmental sustainability and will be the first GREEN Library in Manhattan. The branch is expected to receive LEED Gold certification from the U. S. Green Building Council. Some of the features contributing to the branch’s environmental efficiency include:
 

• an efficient technologically advanced low-energy heating/cooling system

• low-flow sanitary fixtures which reduce water consumption

• low-energy lighting system

• use of recycled and renewable building materials including a wood floor constructed with off-cuts from window frame manufacture, carpets constructed from old truck tires, millwork made from recycled cardboard composite, and terrazzo with recycled glass and mirror aggregate

• the inclusion of a dedicated area for the collection and storage of all recyclable materials accumulated during the day to day operations of the branch

• use of a large number of the products that are low emitting in order to help the overall indoor air quality.

“Libraries play an important role in communities throughout the city, serving as a place for people to gather, attend readings, access the internet and more,” said Mayor Michael Bloomberg. “The new environmentally-sustainable Battery Park City branch will be a model for future branch designs and an asset for the local community for decades to come.”

“Expanding literacy, arts and education to any neighborhood in New York City is an issue we at the City Council feel is one of the most vital for New Yorkers,” said Council Speaker Christine C. Quinn. “Having access to these materials is essential to the growth of our neighborhoods. Battery Park for so long did not know what it was to have these resources available to them down the street from their homes. Now, residents downtown and throughout the City will be able to enjoy this new branch and the new resources it brings to this beautiful area of our City.”

“The opening of the Battery Park City library is another big step in the continuing progress of the community as one of the great neighborhoods in our city,” said New York State Senator Daniel Squadron. “Public libraries are more important than ever in the 21st century, in which broad, democratic access to information–whether printed or digital–is more important than ever.”

“I am delighted to join Battery Park City residents in welcoming the newest branch of the New York Public Library to the neighborhood,” said United States Congressman Jerrold L. Nadler. “I am proud of this terrific New York institution and believe that it profoundly enriches the lives of those who use it. As a lifelong enthusiastic reader and library patron, I hope that residents will enjoy this library as much as I have always enjoyed my local libraries and read to their hearts’ content.”

“I am thrilled to be joining the New York Public Library and the residents of Battery Park City in opening this beautiful new library,” said Councilmember Margaret Chin. “To have a public facility like this, in a community like Battery Park City, is really wonderful, especially with the construction’s focus on environmental sustainability and what we hope will be a LEED Gold certification. It’s important that we teach our children about the environment as we instill in them a love of reading and learning, while providing a great place for our seniors and others in the community to read and gather. I also want to specifically recognize my predecessor, Councilmember Alan Gerson, without whose work this library simply would not exist, and also the work of Community Board 1 Battery Park City chair Linda Belfer, a tireless champion of all things Battery Park City.”

“As Chair of Cultural Affairs, Libraries and International Intergroup Relations, I am ecstatic that this library has been finished,” said Council Member Jimmy Van Bramer. “Any day that a library opens is a very good day for the community it serves. This library will enhance the educational and cultural life of the neighborhood.”

“The new Battery Park City library and the expansion of New York Public Library services means the promotion of literacy, education and technology for local residents,” said New York City Council Member Vincent Gentile. “Public libraries, particularly ones developed in an environmentally friendly way like this one, enrich the neighborhoods in which they’re placed; it’s a joy to see all the benefits that come along with a new public library being introduced to a neighborhood that didn’t have those resources at their fingertips before.”

LOS ANGELES — A California lawmaker wants to make his state the first to ban incandescent lightbulbs as part of California’s groundbreaking initiatives to reduce energy use and greenhouse gases blamed for global warming.

The “How Many Legislators Does it Take to Change a Lightbulb Act” would ban incandescent lightbulbs by 2012 in favor of energy-saving compact fluorescent lightbulbs.

“Incandescent lightbulbs were first developed almost 125 years ago, and since that time they have undergone no major modifications,” California Assemblyman Lloyd Levine said Tuesday.

“Meanwhile, they remain incredibly inefficient, converting only about 5 percent of the energy they receive into light.”

Levine is expected to introduce the legislation this week, his office said.

If passed, it would be another pioneering environmental effort in California, the most populous U.S. state. It became the first state to mandate cuts in greenhouse gas emissions, targeting a 25 percent reduction in emissions by 2020.

Compact fluorescent lightbulbs (CFLs) use about 25 percent of the energy of conventional lightbulbs.

Many CFLs have a spiral shape, which was introduced in 1980. By 2005, about 100 million CFLs were sold in the United States, or about 5 percent of the 2-billion-lightbulb market, according to the U.S. Environmental Protection Agency.

That number could more than double this year. Wal-Mart Stores Inc. alone wants to sell 100 million CFLs at its stores by the end of 2007, the world’s biggest retailer said in November.

While it will not give opinion on the possible California law, the EPA recommends CFLs.

“They save money and energy,” EPA spokeswoman Enesta Jones said. “They are more convenient than other alternatives and come in different sizes and shapes to fit almost any fixture.”

Also, CFLs generate 70 percent less heat than incandescent lights, Jones said.

About a fifth of the average U.S. home’s electricity costs pays for lighting, which means even if CFLs initially cost more than conventional lightbulbs, consumers will save, Jones said.

A 20-watt CFL gives as much light as a 75-watt conventional bulb, and lasts 13 times longer, according to the Rocky Mountain Institute, a nonprofit group studying energy issues.

Southern California Edison, an Edison International subsidiary and one of the state’s biggest utilities, runs a program that cuts the cost of a CFL by $1 to $2.50. In the past year, SCE has helped consumers buy 6 million CFLs, it said.

California Energy Commission member Arthur Rosenfeld said an average home in California will save $40 to $50 per year if CFLs replace all incandescent bulbs.

While not commenting specifically on Levine’s likely legislation, Rosenfeld, winner of the Enrico Fermi Presidential Award in 2006, said the switch from incandescent bulbs became feasible about five years ago when CFL performance improved.

“This is clearly an idea whose time has come,” he said.

Levine, a Democrat from Van Nuys in Los Angeles, last year introduced a bill that will become law in July that requires most grocery stores to have plastic bag recycling.
