For People A Green Vocabulary

The international passion to protect our planet from the ravages of pollution and to preserve our natural resources for future generations has become an everyday fact of life. With international support by “green” political parties, consumer organizations, celebrities and politicians, the green movement has become a powerful force with an agenda that needs to be addressed by industry, politicians and consumers. Discussions about the environment are taking place in corporate board rooms, legislative hearings, and by consumers in supermarkets and department stores.

Can we fully understand environmental concerns and energy implications without a working knowledge of basic green vocabulary? Do we understand all the issues relevant to tax incentives for oil companies? Can we properly compare the organic and nonorganic products that we decide to eat or wear every day? In essence, to think and live green you need to speak and understand green.

Understanding some key green terms and their implications can help us evaluate alternatives between our planet and sacrificing aspects our personal lifestyle. It can help us decide how we cast our vote or spend our money or how we live our lives. A green vocabulary can help us reduce our “carbon footprint “. The following represents what is best described as a green vocabulary of definitions and commentary to help eco-oriented consumers make informed green decisions.

A Green Vocabulary for Green People

Organic identifies products made under the authority of the Organic Foods Production Act. Organic production guidelines are established to use organic materials and practices that improve ecological balance. Organic production incorporates agricultural system components to enhance natural biological systems.

Organic Agriculture is an ecological farming system that promotes natural chemical and biological cycles that improve soil fertility and maintains a balanced and productive farming system. Any products introduced to this system for fertility or pest protection are of natural composition. It eliminates the use of harmful synthetic pesticides, herbicides, fertilizers, growth stimulants or antibiotics. These essential restrictions can reduce contamination or pollution to our air, water or food supply.

Natural Fibersare “certified” organic fibers derived from organic agriculture such as cotton, bamboo and hemp.

Certified Organic Cotton is derived from organic agriculture. The cotton is grown without artificial pesticides or fertilizers. Conventional cotton farming ranks about fourth in the use of pesticides in the US. Several of the top pesticides used in nonorganic cotton farming are EPA recognized carcinogens. It takes 1/3 of a pound of pesticides and synthetic fertilizers to make one organic T-shirt disregarding the use of any toxic dyes (Organic Trade Association). A typical organic tee shirt is also about the same weight but without these harmful chemicals. Organic cotton is produced using conservation minded or “sustainable” approaches to crop production. Such practices help to retain and promote soil fertility and the natural recycling of soil resources.

Organic Certification is provided by various organizations. The most widely recognized standards are GOTS (Global Organic Textile Standard) which is the basis for the statement “100% certified organic cotton” used by many green companies.

Fair Labor Practices are not necessarily restricted to agriculture but generally support fair wages and healthy working conditions.

Fair Trade Certification “…guarantees consumers that strict economic, social and environmental criteria were met in the production and trade of an agricultural product.”(www.transfairusa.org).

Sweatshop-free describes the absence of manufacturing conditions currently existing in many countries, referred to as “sweatshops”. They are production facilities or factories where goods are produced cheaply by minimizing workers’ salaries, and increasing working hours. Proper environmental health standards are diminished, yet demands for high levels of productivity still remain. These sweatshops may thrive from corporations seeking to increase profits by subcontracting inexpensive labor.

Sustainable means conserving and preserving limited natural resources and energy supplies. It is connected with the term “recycling” when natural products are re-used like rubber (for tires, shoes) or paper/trees (for books, business cards, magazines etc.), or wood (for recycled furniture). They are made from or made into recycled, carbon based products. A good example of preserving our resources is Trees for the Future, a charitable organization dedicated to replacing and planting trees. Unfortunately, most of our energy production is derived from organic (carbon based) fossil fuels that cannot be recycled as compared to wind or solar energy. All of this is connected to our lifestyle and our “carbon footprint” discussed next.

Carbon Footprint is a descriptor of environmental impact. It describes the consumption of carbon based natural resources or the production of carbon by-products like carbon dioxide, carbon monoxide or “greenhouse emissions”. It’s about lifestyle and the amount of carbon based resources we consume through transportation, climate control, manufacturing etc. Basically it relates to how much each of us consume in terms of natural resources to meet our needs. In general each of us should be committed to reducing the size of our “footprint” to sustain resources for present and future generations.

Eco-fashion is a general term describing organic clothing that has addressed the needs of the environment as well as socially responsible working conditions.

Eco-friendly suggests a product or process than has a reduced impact on the environment.

Low Impact Dyes refers to dyes used the manufacture of goods that should have minimal impact on the environment. Sometimes the term non-toxic is used here as well.

Green is a generally positive term referring to the environment, organics or even a green lifestyle to be discussed shortly.

Conscientious Clothingdescribes organic clothing has addressed environmental, ethical and socially responsible standards.

The Green Lifestyle

Green Lifestyle or Green Living describes a lifestyle reflecting a strong commitment to the environment. In addition, it addresses compassionate and positive thinking. It means choosing a life with charitable deeds and practices, reflecting compassion for the environment and others. Green living is being proactive and incorporates spiritual growth leading to ethical thinking.

Social Responsibility can be defined as accepting responsibility for others and taking action against social injustice. It includes meeting the needs of others through charitable giving.

Charitable Giving describes a sense of genuine compassion and reacting to it with charitable practices towards others.

In summary, a green lifestyle represents caring for the environment combined with positive thinking leading to ethical behavior and compassionate living. Ultimately, your deeds represent positive thoughts in action. The result can be a clean, safe environment and a better quality of life for yourself and others.

If you learned some green vocabulary, be sure to use it to make decisions and set priorities in your life. Think about adopting a greener lifestyle!

A Carbon Footprint is Impacted by Fugitive Refrigerant Gas Emissions

The United States and a host of other foreign countries are focusing on fugitive emission tracking for certain industries. The goal is to identify the amount of substances that are emitted into the atmosphere when a refrigerant gas leak occurs. This will give government officials at the EPA a better understanding of the amount of greenhouse gases harming the environment each year and contributing to global warming due to the ineffective management of refrigerant gases.

Fugitive emission takes place when an unexpected leak of a hazardous substance occurs in a system and the discharge is not contained in a vent, stack, or duct. This may be caused by a component failure, poor servicing, or a breakdown in some industrial process. When a system containing refrigerant leaks, these high global warming potential substances cause damage to the atmosphere. Certain refrigerant gases are not broken down in the atmosphere and end up entering the stratosphere and destroying the protective ozone layer over time.

Across the U.S. economy, refrigerant gases or fugitive emissions equal over 300K tons of carbon dioxide each year. Other countries have similar or worse outputs. Many environmental regulations, such as The Montreal and Kyoto Protocols, exist to reduce the escape of harmful substances, like refrigerants, into the atmosphere over time. There are additional goals to reduce the potential for global warming in the near future and to improve air quality in the long term by reducing the emissions refrigerant gases.

A select few refrigerant gases have multiple detrimental effects on the environment. Not only are they ozone depleting substances but they are also chemicals with a high global warming potential (GWP) which places them into the category of greenhouse gases which lead to global climate change. For many reasons, it is important to effectively monitor, track, and report refrigerant gas usage.

The EPA has finalized its rules pertaining to any fugitive emission occurrence, whether through evaporation or a leak. The regulations apply to several industries, including existing and newly constructed facilities with systems using refrigerant gas in their workplace heating and cooling systems. Other industries are industrial chemical manufacturing, electric services, pulp and paper mills, and petroleum refinancing.

Tracking fugitive refrigerant gases is required by facilities owning or operating HVAC-R systems or by manufacturers who produce them. The EPA has identified a number of dangerous compounds, among them chloroflurocarbons, hydrofluorocarbons, methyl bromide, halons, methyl chloroform, and carbon tetrachloride.

A particular concern for fugitive emission problems is with refrigerant gas, because it contains chloroflurocarbons and hydrofluorocarbons, two primary contributors to the weakening of the ozone layer and the increase in greenhouse gas volumes. Furthermore, refrigerant gas is used across many industries in refrigeration and cooling units, ventilation and air conditioning systems, and fire protection systems.

When a fugitive emission occurs, businesses are required to track the refrigerant leak rates and report annul refrigerant usage it to the EPA. One of the primary emissions scopes, fugitive refrigerant gas emissions are an integral part of an organizations carbon management requirements. Of the utmost importance is the determination of the HVAC-R system that is leaking and the capturing of the service event detail related to fixing the leak. Systems containing refrigerant gases must be inspected by EPA certified technicians and all service events must be logged when refrigerants are handled.

The new fugitive emission regulations provide a more standardized approach to thresholds identified by the U.S. Clean Air Act at the direction of the EPA. These include continuous monitoring, tracking of leaks, and reporting of leak repair, and containment.

Web applications and specialized tools can increase an organization’s efficiencies related to HVAC-R system maintenance, improve accuracy of refrigerant inventories thus saving money, and turn manual processes into a centralized, automated work flow. Development firms who specialize in the area. They ensure compliance and reduce the likelihood of substantial fines.

Water Efficiency

In my four-article series on water use (The Resource Matrix), I took you on a journey to reveal the layers of The Resource Matrix in order to help you understand how water will be a highly contested commodity tomorrow, possibly as much as oil is fought over today.

You learned about your water footprint and a website where you can calculate it, virtual water and virtual water transfers, whereby choices here affect water availability elsewhere, to the point of some people not having enough water to drink in order to produce inexpensive dyed cotton, along with insane choices such as growing crops in the desert.

You learned that on average it takes 1854 to 3000 gallons to produce one pound of beef.

Yep, it’s it’s been a great journey through the sidetrip city of the Resource Matrix.

Today, we’ve found the on-ramp to the Green Lighting Interstate and are driving to take a look at water use in generating electricity.

For a simple reason. It takes a lot of water to produce electricity.

How much? 5% of all US water? 10%? Can’t be as high as 25%?

Electricity and water?

I thought the issue was fossil fuels and greenhouse gases

The U.S. Geological Survey (USGS) estimated water use in the United States in 2000.

Their grand total: 408 billion gallons per day withdrawn for all uses.

The number 1 spot, weighing in at 48%, was thermoelectric power.

Irrigation earned the runner-up prize at 34%.

The 195 billion gallons need to come from somewhere, and actions have consequences. Environmental ones, as in 40 million fish in the Great Lakes killed each year due to being trapped against water intake devices. That’s a lot of Friday night fish dinners.

How much water is used in generating electricity?

Large fossil fuel and nuclear plants require incredible quantities of water for cooling and ongoing maintenance.

Water for thermoelectric power is used in generating electricity with steam-driven turbine generators. It uses 48% of all water in the US.

According to the Pace Energy and Climate Center, the amount of water used for power plant cooling varies by each specific power plant’s electricity generating technology and size. Nuclear reactors require the most water for cooling, and baseload fossil fuel power plants come in second.

The Salem Nuclear Generating Station alone takes 3 billion gallons a day from the Delaware Bay, according to the Pace Energy and Climate Center.

Nationally:

• Steam electric generating plants across the nation draw in more than 200 billion gallons per day.
• Nuclear and fossil fuel power plants drink over 185 billion gallons of water per day.
• Geothermal power plants add another 2 billion or so gallons a day.
• Most renewable energy technologies require little or no water for cooling.

These numbers are starting to sound like the same ones the U.S. Treasury and Federal Reserve Bank use.

Imagine watching your favorite science program where astronomers explain that the universe is 78 billion light-years wide (78 billion units of 5,878,630,000,000 miles). There is absolutely nothing in our experience to help us wrap our mind around it.

How much is 3 billion gallons per day?

The Delaware Bay feeds Salem Nuclear Generating Station 3 billion gallons a day.

Imagine this rectangle: a football field with end zones (360 feet long x 160 feet wide). Then add to it walls on each side of the rectangle to create a container to hold the 3 billion gallons you pour into it.

How high do you need to make those walls to contain 3 billion gallons? 6915 feet high. Or 1.3 miles.

Maybe 6915 feet high is still hard to imagine. So how deep do you cover the field in order to feed the Salem plant every minute? Answer: 5 feet deep. Every minute.

48% of all water use: We’re Number One!

How much is 195 billion gallons per day?

Using the USGS figure for 2000, thermoelectric power nationwide used 195 billion gallons a day, or 48% of all water used in the US. My guess is the water use has grown since then.

How high are the walls on our football field now? 449,475 feet or 85 miles high. We’re back to US Treasury and astronomy numbers again.

So, let’s get a higher-level view to help us.

Lake Erie holds 116 cubic miles of water.

Nationally, thermoelectric power uses 195 billion gallons a day – or 64.2 cubic miles a year.

We drain Lake Erie every 22 months.

But the water used is returned to its source.

So what’s the issue about water use?

Power generation returns 98% of the water back to its source (bay, lake, river, ocean).

It’s the environmental consequences.

The Pace Energy and Climate Center explains it neatly:

Withdrawal of large volumes of surface water for either power plant cooling or hydropower generation can kill fish, larvae and other organisms trapped against intake structures (impinged), or swept up (entrained) in the flow through the different sections of a power plant.

Examples include:

• The Salem Nuclear Generating Station is responsible for an annual 11 percent reduction in weakfish and 31 percent reduction in bay anchovy.
• At the Indian Point 2 and 3 reactors on the Hudson River, the number of fish impinged totaled over 1.5 million fish in 1987.
• The 90 power plants using once-through-cooling on the Great Lakes kill in excess of 40 million fish per year due to impingement. (Once-through cooling needs a continual flow of new water, and uses 30 to 50 times that of a closed cycle system. Closed cycles cool down water from steam then reuse it.)

The diversion of water out of the river removes water for healthy in-stream ecosystems:

• Stretches below dams are often completely de-watered.
• Fluctuations in water flow from peaking operations create a “tidal effect,” disrupting the downstream riparian community that supports its unique ecosystem.
• A dam’s impoundment slows water flows, which hinders natural downstream migration of many fish species.
• By slowing river flows, dams also allow silt to collect on river and reservoir bottoms and bury fish spawning habitat. Silt trapped above dams accumulates heavy metals and other pollutants. Disrupting the natural flow of sediments in rivers also leads to erosion of riverbeds downstream of the dam and increases risks of floods.
• The impoundment of water by hydropower facilities fundamentally reshapes the physical habitat from a riverine to an artificial pond community.
• This often eliminates native populations of fish and other wildlife.
• Dams also impede the upstream and downstream movement of fish and other wildlife, and prevent the flow of plants and nutrients. This impact is most significant on migratory fish, which are born in the river and must migrate downstream early in life to the ocean and then migrate upstream again to lay their eggs (or “spawn”).
• As mentioned above, withdrawal of water into turbines can also impinge or entrain significant numbers of fish.

The cleanest kilowatt is the one never used:

Back to those compact fluorescent lamps and LEDs

PowerScorecard.org explains the solution:

By re-directing electricity dollars to support environmentally benign energy resources, consumers are empowered, in states that offer supply choice, to influence the existing generating resources that are deployed to meet demand.

They can also support the construction of new and cleaner electricity resources that will be built to meet overall growth in demand in the future. By supporting these power options, consumers can minimize many water use and consumption impacts. Still, directing your dollars to cleaner power products in no way helps remediate damages that already have occurred. Consumers can stop the construction of new hydropower facilities or alter conditions of siting and operation, but they cannot undo previous environmental degradation that occurred at existing hydropower facilities.

In short, reduce your use of electricity.
