What Makes a Home a Green Home?
What Makes a Home a Green House?
One of the hottest topics today is about being environmentally friendly. There are many ways to become environmentally friendly about the home including water preservation and energy reduction. This not only helps with a positive action by reducing your impact on the environment, but will also save you money!
Lets take a look at what makes a home green.
Reduced Energy Use
Energy comes in many forms such as electricity, natural gas, oil, etc. The creation or use of this energy results in greenhouse gas emissions that affect our planet in a negative way.
Methods of Reducing Energy Usage
Insulation, One of the best things that you can do to make a green home is to ensure that the walls, windows, attic, and floors are all well insulated and draft free. The majority of the energy used in a home goes towards heating the house. Insulation will prevent the air temperature from escaping the home and save you money on your utilities.
Energy Star Appliances When one of your appliances has reached it’s end of life, or when you are building a new home, consider installing an appliance that meets energy star requirements. This will ensure that it will use over 30 percent less electricity or fuel than a typical appliance of that type.
Other options include advanced mechanical Systems On demand tankless water heaters, geothermal HVAC equipment, and even solar power is a great way to reduce the amount of energy that is wasted to run the plumbing, heat and air, and electrical systems in the home. While they can have a higher upfront cost than a typical unit of its kind, tax incentives from the government can offset a good deal of the extra cost and allow you to make the money back within a few years time.
Reduced Water Use
Water is another essential resource that can be preserved in our day to day use around the house.
Low Flow Fixtures Many low flow shower heads and toilets developed a bad reputation in the past because they could not live up to their less efficient counterparts. Fortunately, todays better engineered models and aerators allow you to experience the luxury and ease of use that you prefer, while additionally using a significantly lower amount of water.
Efficient Clothes Washers Many of the newer front loading clothes washers use as little as half of the water of a typical top loading washer. For families who are constantly putting in a new load of dirty clothes, this can lead to a significant savings in cost and water usage over time.
Use Rain Water For Irrigation For those who want to really cut down on water usage, storage tanks that collect rain water during a storm for latter use to water the garden and lawn can save thousands of gallons over the span of a summer.
These are just a few of the many ideas out there that will help ensure that your home is green. Environmentally friendly decisions in the home can lead to wallet friendly results over time and allow for the satisfaction of knowing you are reducing your negative impact on the planet.

Global Warming: More Inconvenient Truths
It’s not just the planet that’s hotting up, it’s the whole debate about global warming. Especially now that we can see and feel its effects every day. Yet you’ve probably noticed that when it comes to taking action, the focus always seems to be on what each of us can do personally. We the people must use energy-saving light bulbs, fly less, recycle, use green energy, take our appliances off standby, and so on. But perhaps, like me, these entreaties leave you feeling a bit ripped off. Perhaps you, too, are wondering what part business, industry and governments have to play? It’s certainly true that there are things individual citizens can and must do, but surely really significant reductions ultimately depend on tough, international legislative action. After all, if personal responsibility were all that has ever been necessary to solve problems, why were political systems and governments invented in the first place? Once we’ve taken individual action, is that it? Or is there more to be done? What really seems to be needed is a way of acting collectively to ensure that governments around the world start co-operating to solve global warming instead of talking more hot air while the planet burns.
In his film, An Inconvenient Truth, Al Gore rightly points out that collective action depends on political will, but this, he says, is in short supply. Right again! The reasons for its scarcity, he suggests, are that it’s simply not in the short-term interests of the main polluting nations and their industries to take substantive action. So far so good, but the cartoon image he uses to hammer his point home is an unfortunate one: a pair of scales with gold bars on one side and the entire planet on the other. Gore uses this to demonstrate the absurdity of those who see economic prosperity and a healthy planet as an either/or choice: after all, what value could gold bars have if there’s no habitable planet in which to enjoy them? It’s plainly ridiculous, and so too, suggests Gore, is the reluctance of some to give up the gold bars.
But rather than ridicule those who fear for their short-term interests, shouldn’t we be trying to look at what may be their perfectly legitimate point, and trying to understand the forces that keep it relevant? Gore may have faced the inconvenient truth of global warming, but he is yet to face a second inconvenient truth: that stiff action on the part of the rich countries WILL have adverse economic effects, at least in the short term. And if global warming is dealt with in isolation, those costs WILL fall heaviest on the USA and on other big polluters. To deny the barrier to action that these short-term costs and disincentives represent, as Gore seems to, is to fall into the same trap as those who deny global warming itself.
I laughed along with everyone else when I saw the gold vs earth cartoon, but making fun of those who are wary of economic backlash is hardly likely to elicit the consensus Gore seeks. It also seems like a cheap shot when you keep in mind that had Gore actually become President in 2000, he would inescapably have joined the ranks of those he’s poking fun at. The president of the U.S. has only four years before facing another election, so Gore’s popularity and tenure in office would have been directly influenced by his corporate funders and their support for short-term gains to the US economy.
Today, there may only be few people who still cling to denying global warming. But knowledge and acceptance can’t effect change by themselves. What is urgently needed is a means to unlock the short-term barriers and disincentives that prevent decisive collective action – nationally and internationally. Make no mistake: in today’s globalised and largely borderless world, capital and jobs generally move to wherever in the world environmental and social costs are lowest and profits therefore highest. Any government moving first to significantly increase environmental costs or regulations in a bid to reduce emissions would definitely see investment and jobs moving elsewhere, thus making the nation uncompetitive. That’s why nothing changes except the level of carbon dioxide in the atmosphere just keeps on rising. Prime Minister Tony Blair at least seemed to recognise these realities when he pointed out that “The blunt truth about the politics of climate change is that no country will want to sacrifice its economy in order to meet this challenge”.i
Unlike Gore, Blair clearly recognises this second inconvenient truth and he should not be blamed for stating it. But his statement only holds true IF nations fail to act together. This is the barrier that keeps the gold bars firmly on one side of the scales. However, if all nations co-operated, the necessary regulations could be implemented without any nation fearing capital or employment flight because there would be no low-cost haven for them to run to. Corporations, too, would have nothing to fear because all corporations would be subject to the same additional costs, so maintaining their relative competitiveness and their relative profitability. Think about that for a minute.
But there is a further problem: the biggest polluter, the USA, would have the biggest adjustment cost, so it has the least incentive to sign up to any cooperative agreement. This is why the Kyoto Protocol is not supported by the USA and Australia, another big polluter. It is also why the provisions of the Kyoto agreement are so mild and relatively ineffectual. Because if the nations supporting Kyoto agreed to tougher, more significant curbs, the costs involved would make them uncompetitive with nations, such as the USA and Australia, who refuse to participate.
The net result is a recipe for missed targets and an intergovernmental dead-lock of a kind which raises the third, final and most important inconvenient truth; this time one that concerns not so much governments or businesses but each of us as individual citizens. It’s a truth which all citizens around the world must urgently take on board: that we can no longer abdicate responsibility for taking collective action to politicians and governments alone. If free-riding governments are to be compelled to co-operate, then it must be citizens who force them to do so. We have no choice but to take the initiative, and stop assuming that politicians are in the driving seat of the global economy. It’s time to grab hold of the steering wheel and find a way of driving our politicians and governments toward co-operation. What’s needed is a method of achieving cooperation which removes the barriers and objections, takes away the fears of being uncompetitive, and replaces those fears with an enthusiasm for shared problem-solving.
When Al Gore became fully aware of the dangers of global warming, he travelled far and wide to gain a deeper understanding of the science and its real-world effects, and justifiably so (although I do hope he planted plenty of trees to personally offset his carbon emissions). But Gore and the rest of us have so far failed to embark on another, far more urgent line of enquiry. If we genuinely wish to solve global warming and other global problems, we need to gain a deeper understanding of the barriers to collective government action under globalisation. For the deeper truth is that global warming and many other global “problems” are not the real problems at all. They are merely symptoms, albeit terrifying ones, of our failure as a global human society to co-operate. Until we understand the dynamics of co-operation and how to achieve it, and what we as citizens can do to unblock the barriers to it, international inaction, missed targets and deepening chaos will continue and global warming may well destroy human civilisation.
The Simultaneous Policy, a global citizen’s initiative, claims to have begun this vital journey and to offer a plausible and effective way that citizens can use their right to vote in a new way that drives the politicians of all parties and nations to collectively implement the measures we so desperately need. It seems that political representatives would find it a welcome relief to be freed from the restrictions that keep them beholden to big business interests and confined to wholly inadequate policies dictated by the need to keep their nations “internationally competitive”. This is reflected in the fact that already politicians from opposing sides of the spectrum – nationally and internationally – are pledging their support for the Simultaneous Policy as a result of voter pressure and/or enlightened social responsibility. Check it out for yourself at www.simpol.org – as Noam Chomsky commented, “Can it work? It’s certainly worth a serious try!”
The Lowdown on Global Warming
Global warming and climate change are matters that have increasingly been in the public eye in recent times and worldwide action is being taken to tackle the affect these two factors have on the environment.
Global warming results in climate change which in turn has implications for everyday activities and factors, such as growing crops and nature conservation.
Global warming is an increase in the average temperature of the earth’s atmosphere and a sustained increase causes climatic change and alters long-term weather patterns. The world is experiencing global warming because too much carbon dioxide is being released into the atmosphere.
The carbon rises to the earth’s upper atmosphere where it acts like an insulating coat, reflecting heat from the sun back to the earth’s surface.
Changes to the climate come with potentially damaging consequences. Ice caps are starting to melt at the Poles, which could cause sea levels to rise. Higher temperatures and less rainfall are being recorded in areas which already suffer from drought.
One of the main sources of carbon is the burning of fossil fuels for energy, typically used to heat homes and run vehicles like cars and motorbikes.
More and more energy providers are recognising the negative effects of climate change and introducing different ways of tackling the issue.
There are several ways in which you can also help to combat climate change. Buying green energy is a good way of helping to reduce some of the causes of climate change.
Look for providers who use clean, renewable sources which are better for the environment. Some providers offer green energy at the same price as the standard service so doing your bit for the earth wouldn’t cost you any extra.
You could also investigate the possibility of making your own energy. Solar panels can generate electricity and hot water for your home which saves you money and reduces carbon emissions. Some providers even offer to buy back any excess electricity you generate so you can be sure energy is not being wasted.
There are also ways you can save energy around the home. Cavity walls and roofs account for the majority of heat lost in the home so insulating these areas significantly reduces consumption. Fitting a jacket around your hot water tank also helps to conserve gas and electricity.
Have your boiler serviced regularly to make sure everything is in working order and replace any old devices as they can run inefficiently and use more energy than need be.
When it comes to the devices you use around the home you can save pennies by doing a few simple things.
Avoid using the standby button as this can actually use more energy than what is required to operate the appliance in the first place. Simply switching off your electrical items instead of using stand-by can save several pounds each month and decreases energy consumption.
UK Must cut Emissions By 60%
The Committee on Climate Change has called on the UK to cut its emissions by 60% compared to 1990 levels over the next twenty years.
In its report ‘The Fourth Carbon Budget – Reducing emissions through the 2020s’ the committee puts the case for creating a new marker in the battle to cut emissions.
Currently most targets are aimed at cuts on 1990 emissions levels before 2050. however to drive the fight against climate change the committee suggests a plan as part of a carbon budget for 2023 to 2027 and a target for emissions reductions in 2030, which would be halfway between now and 2050.
The recommended target for 2030 is to cut emissions by 60% relative to 1990 levels, or 46% relative to current levels, which needs a 62% emissions reduction from 2030 to meet the 2050 target in Britain’s Climate Change Act.
The committee estimates the recommended target can be achieved at a cost of less than 1% of our Gross Domestic Product (GDP), or as it states in the report ‘a fraction of one year’s growth’ over the next two decades.
It also backs that new carbon budgets should be legislated by summer 2011, as required under the Climate Change Act.
Committee on Climate Change chair said: “We are recommending a stretching but realistic fourth carbon budget and 2030 target, achievable at a cost of less than 1% of GDP. “Any less ambition would not be compatible with the 2050 target in the Climate Change Act. “We therefore urge the Government to legislate the budget we have recommended, and to develop the policies required to cut emissions over the next two decades. “The case for action on climate change is as strong as ever: climate science remains robust and suggests that there are very significant risks if we do not cut emissions. And countries acting now will gain economic benefits in an increasingly carbon constrained world.”
The CBI’s director of business environment, backed the new 2030 target. He said: “We support the UK’s existing climate change targets for 2020 and 2050 and businesses are already taking steps to measure and reduce their emissions. “The Committee’s proposal for an extra staging post at 2030 could provide additional clarity for investors, but the feasibility of the proposed target would need to be examined in detail. “Investors will only commit to low-carbon projects if they are confident about the policy framework in the long-term. “The Government’s forthcoming announcements on reform of the electricity market and work to simplify the Carbon Reduction Commitment will be crucial tests.”

Solar Tower – renewable energy green global warming
EnviroMission Limited (www.enviromission.com.au) produced this 5 minute video on the pilot plant in Spain. It is an older video (2000) but gives a decent understanding of the solar tower concept. EnviroMission, Ltd. (US Market: EVOMY, Australian Exchange: EVM) is a renewable energy developer of sustainable “green” energy solutions for the energy market. EnviroMission aims to be one of Australia’s leading producers of clean renewable energy. EnviroMission holds the proprietary rights to Solar Tower technology, a large-scale renewable energy technology based on simple fundamentals of physics — hot air rises. Solar Tower technology has the potential to offer competitive renewable energy with equal reliability to fossil fuel generators. A single 200MW Solar Tower power station will provide enough electricity to power around 400000 households. The energy output will represent an annual saving of more than 1960000 tonnes of greenhouse CO2 gases from entering the environment when compared to brown coal emissions in Victoria. The greenhouse savings equate to the removal of approximately 500000 cars from the road. The Australian Solar Tower project consists of six distinct phases, the first two of which (project optimization and pre-feasibility commercialization) have already been completed. The third phase (final feasibility), paving the way for the implementation of the next three phases (final design, construction, and commercial operation).
New Plastic Recycling Discovery!
A new technique has been devised to recycle plastic which would normally end up in landfill.
Currently approximately 12% of plastic found in household plastic and packaging is currently processed.
Now, however, a process has been developbed by Warwick University which could mean 100% of this type is waste can be recycled.
Municipal plastic solid waste is often too time-consuming and labour intensive to separate and clean and ends up going straight to landfill rather than being recycled.
Engineers at the University have invented a process that can cope with every piece of plastic waste and can even break some polymers, such as polystyrene, back down to its original monomers.
The researchers have devised a unit which uses pyrolysis (using heat in the absence of oxygen to decompose of materials) in a ‘fluidised bed’ reactor.
Tests have shown that the researchers have been able to literally shovel in to such a reactor a wide range of mixed plastics, which can then be reduced down to useful products. Many of these products can then be retrieved by simple distillation.
The products the Warwick team have been able to reclaim from the plastic mix include: wax that can be then used a lubricant; original monomers such as styrene that can be used to make new polystyrene; terephthalic acid which can be reused in PET plastic products, methylmetacrylate that can be used to make acrylic sheets, carbon which can be used as Carbon Black in paint pigments and tyres, and even the char left at the end of some of the reactions can be sold to use as activated carbon at a value of at least £400 a tonne.
This research could have a significant impact on the budgets of local authorities and produce considerable environmental benefits.
The lead researcher on the project, University of Warwick Engineering Professor Jan Baeyens, said:
“We envisage a typical large scale plant having an average capacity of 10,000 tonnes of plastic waste per year.
“In a year tankers would take away from each plant over £5 million worth of recycled chemicals and each plant would save £500,000 a year in land fill taxes alone.
“As the expected energy costs for each large plant would only be in the region of £50,000 a year the system will be commercially very attractive and give a rapid payback on capital and running costs.”
The work will be of great interest to local authorities and waste disposal companies who could use the technology to create large scale reactor units at municipal tips which would produce tanker loads of reusable material.

Satellite Images and Digital Elevation Models (DEMs) Help Monitor Global Warming and Climate Change
Since 1990’s a new generation of satellite sensors with powerful capabilities have been launched to collect massive amounts of data about our planet and the many changes it has experienced.
There are dozens of remote sensing satellites orbiting the Earth collecting invaluable information about the Earth’s surface, oceans and the atmosphere and how they interact. Satellite images have been collected for scientific and technical purposes as well as just appreciating its simple beauty. These satellites collect information that our eyes cannot, collections from 30M to 0.5M resolution is now available.
To view original story with images go here http://news.satimagingcorp.com/2009/10/satellite_image_technology_monitoring_global_warming_and_climate_change_.html
Satellite images provide important land coverage information for mapping and classification of land cover features, such as vegetation, soil, water and forests for monitoring and managing Earth’s vital natural resources and the current global climate changes.
The Earth’s climate has changed throughout history. From glacial periods (or “ice ages”) where ice covered significant portions of the Earth to interglacial periods where ice retreated to the poles or melted entirely – the climate and the Earth has continuously changed.
The shallow end of the Glaciers are melting swiftly. Glaciologists have determined that areas of the glacial lobe were 98 feet lower in 2004 than they were in 2000. That’s double the rate of pre-1999 thinning.
The current warming trend is of particular significance because most of it is very likely human-induced and proceeding at a rate that is unprecedented in the past 1,300 years.
Scientists have been able to piece together a picture of the Earth’s climate dating back decades to millions of years ago by analyzing a number of surrogate, or “proxy,” measures of climate such as ice cores, boreholes, tree rings, glacier lengths, pollen remains, and ocean sediments, and by studying changes in the Earth’s orbit around the sun.
Earth-orbiting satellites and other technological advances have enabled scientists to see the big picture, collecting many different types of information about our planet and its climate on a global scale. Studying this data collected over many years reveal the signals of a changing climate.
Greenhouse gas concentrations in the atmosphere will increase during the next century unless greenhouse gas emissions decrease substantially from present levels. Increased greenhouse gas concentrations are very likely to raise the Earth’s average temperature, influence precipitation and increase in storm patterns as well as raise sea levels. The magnitude of these changes, however, is uncertain.
Digital Elevation Models
Satellite images allow scientists to remove vegetation, water and geological cover from the image data which allows them to produce the most detailed available Digital Elevation Model (DEM) of landscape topography. The creation of DEMs will revolutionize geological applications, land-use studies, soil science, and much more to better understand the global climate changes occurring around the world.
Digital elevation models provide details about landscape features which in result, will allow us to clearly make out the shape of our landscape and understand how water, ice, and soil might move across its surface, how it came to be its present shape and how rapidly the changes are occurring.
Global Warming Solutions Act Of California
This briefly explains the essence of the Stationary Equipment Refrigerant Management Program which is the newest integration into the California Global Warming Solutions Act (AB 32).
Information that is related to emerging and existing refrigerant gas monitoring, reporting, tracking and management legislation is communicated here. As with all other pending legislation, the refrigerant management is still subject to many changes.
The California Global Warming Solutions Act or AB 32 was first passed in 2006 taking effect in 2010, which is a comprehensive directive aiming to reduce greenhouse gas emissions by 25% by 2010.
This goal is derived from the increase of greenhouse gasses in California since 1990. To reverse the pollution of 16 years in the United States in less than 14 years, the legislation aims to cut down greenhouse gas emissions to its 1990 levels.
As part of the California Global Warming Solutions Act (AB 32) the Air Resources Board (ARB) has approved an early action measure to reduce high-global warming potential (GWP) greenhouse gas (GHG) emissions by establishing new legislation and defining requirements related to improved monitoring of AC/HVAC systems, enforcement of regulations, reporting of refrigerant usage, and recovery, recycling, or destruction of high-GWP refrigerant gases.
The greenhouse gasses (GHGs) as defined by the California’s AB 32 are identical to those gasses already identified in the Kyoto Protocol and are already being regulated, monitored, and managed by many other countries around the World.
In addition to carbon dioxide (CO2), which is the most widely known GHG, the following gasses are also defined as GHGs with high global warming potential (GWP) carbon equivalent emissions by the AB 32 legislation:
* Methane (CH4): a byproduct of natural geological phenomena and decomposition of waste; the majority of methane is derived from natural gas drilling.
* Nitrous Oxide (N2O): a pollution from exhausts coming from motor vehicles, processes in industries and other industrial pollutants of the air; like methane, nitrous oxide can also be a product of waste decomposition in nature and agriculture.
* Sulfur Hexafluoride (SF6): a gas used for various electrical applications, including gas insulated switchgear. Sulfur Hexafluoride is also being used for applications in experiments.
* Perfluorocarbons (PFCs) & hydrochlorofluorocarbons (HCFCs): a collection of commonly used refrigerant and aerosol gasses with a wide variety of other commercial applications.
Some Ozone Depleting Substances (ODS) are CFCs and HCFCs which are identified in title VI of the US Clean Air Act (Section 608).
Climate Changes Due to Global Warming
While the drastic effects of global warming has been discussed in many scientific circles, had their run on TV and even had major exposure through well-meaning (but sadly inaccurate) Hollywood films, it’s a concern that has a broad political, economic, social and geographical significance to countries all over the world. Quite literally, for all of us, there is nowhere to hide, nowhere to run and we can’t stop the climate from changing. It’s just way too big for us.
How to recognize global warming
Whether or not it’s brewing something good or something bad, Nature always tries to warn us through many signs. The slow process involved in global warming results in many different things and some of its signs include:
Melting of glaciers
Most of the mountain glaciers on our planet that have been monitored for the past 150 years are reportedly shrinking. The glaciers most affected by global warming those located in the lower latitudes and many of them are disappearing. If glaciers continue to shrink, it could affect water supply in areas that depend heavily upon mountain watersheds.
If the scenarios of global warming continue, most of the glaciers that still stand today will disappear by 2100.
Ocean warming
Sea level increase is attributed to warmer temperatures, which in turn result to the melting of ice glaciers. Over the last 100 years, sea level has increased from 10 cm to 25 cm. Projections over the next hundred years indicate that sea level will rise higher, from about 15 cm to 90 cm. Based on the higher figure, that’s about 3 feet.
Translated, this could mean that beaches lose about 50 feet of area for every foot of increase in sea level. Some islands may even disappear beneath sea water completely.
Heat waves
Heat waves and periods of weather that are unusually warm are also signs of global warming. These may come about with varying degrees of their severity and frequency, causing concerns in the economics and health on a global scale.
How global warming brings climate change and what it means to us
The earth’s climate has always been changing, although not at an abrupt rate. There had been periods of warming and cooling in the earth’s 4.65 billion-year history. Strange as it may sound to some, this is the reason why life became possible on this planet millions of years ago. Unfortunately, not all of the changes in climate brought about by global warming may be beneficial to many of us.
For one, global warming will raise the temperatures in some regions of the Northern Hemisphere, causing the melting of mountain glaciers. This means that areas that are currently experiencing light snow may no longer experience snowfall anymore. Snowlines found in mountains in temperate regions may also be higher and packs of snow will melt earlier than before.
Spring may be experienced earlier and temperatures during night time and in winter will rise. The world will experience a more humid atmosphere since sea water will have a higher rate of evaporation. With greater humidity, rainfall is expected to increase on average.
Storms will also occur with more frequency and intensity. Ironically, water in the soil will evaporate faster, causing dryness between rains. Regions that are already considered dry will experience more dryness. Some semi-arid regions in the African continent, for example, may suffer more while areas that depend on their region’s mountain snow packs for irrigation will not benefit from earlier melting between growing seasons.
With warmer weather, some hurricanes will be more severe and winds are expected to blow stronger. It is also possible that wind patterns may shift. Extremely cold periods may be experienced as well.
The phenomenon known as El Nino may occur in more frequency and severity. This is expected to affect different regions in many countries. All in all, scientists will have some difficulty in predicting weather patterns.
With changes in climate brought about by global warming, health concerns and risks may also increase. Heat stress and diseases may become common in places that did not have any problems with them before.
Global warming is an issue that requires immediate action. Even plants and animal species are adversely affected by it. While many of the changes that occur in our planet are totally out of our hands, we have been direct contributors to events that have had negative effects on our environment. This is why many leading social and scientific organizations have urged nations to cooperate in the move to counter this worldwide problem before it’s too late.
