How Does Gas Win An Environmental Debate

Well today in Washington the Senate was debating environmental legislation that will put natural gas in the forefront on generating enough electricity to curb a demand for electricity that has run rampant in recent years.
Coal is to dirty and wind and solar are not dependable enough according to their line of thinking.
There is no doubt coal is dirty as anyone can see simply by looking at a coal miner at the end of the day. At the same time companies are ramping production on photo voltaic cells that are more stream lined as well as more efficient. They should be more cost effective as well. Ampulse Corporation, Golden CO. has raised $8 million along with various partners to step up production of PV products.


“Ampulse has assembled a strong management team along with key strategic partnerships with two renowned laboratories to develop a low-cost, high efficiency, c-Si thin-film PV solution for the residential, commercial, and utility-scale solar markets,” said Daniel Leff.

Wind is well positioned in the market place simply because development has momentum and oil is beginning to be so volatile because of supplies needed in countries like China and India. The shear number of cars alone added to just one of these countries is scary indeed. China's demand for oil alone is to exceed a jump of 150% by 2020.

In any event, the Republicans, today, were clearly trying to either obstruct or derail any progress on environmental policy as the Senate struggles to put rose colored glasses on the rest of the world.

Responsible Camping - Sustainable Camping


We campers are recognizing the significance of an unspoiled environment as a precondition for our activity. We know, that clean and fresh nature is essential for an enjoyable camping - it is the place where we spend our free time, relax with our friends and collect strength for our coming duties.
When camping we are placing a burden on the environment but responsible camping does not endanger the environment. Responsible camping will allow us to enjoy the environment without taking this privilege out from future generations. Showing our responsibility means that we have to adopt to our camping activity only sustainable operating models.

When our goal is to adapt camping to meet the requirements of environmental protection and to steer our activity in a direction which protects the nature and the environment, we can talk about sustainable camping.
Developing sustainable camping requires cooperation between us campers, authorities, campsite owners and also local population. However, we campers, we play a central role in adopting environmentally friendly practices. Whether or not sustainable measures are carried out depends more than anything else on us ourselves.

The following is a brief summary of the basics of sustainable camping:

* In campsite planning environmental viewpoints should be taken into consideration from the beginning.

* When determining the campsite location alternatives which place the least possible burden on the environment should be studied.

* Local traditions should be taken into account in construction. Architecture should be in harmony with the environment and landscape. Construction materials and technical solutions should be environmentally friendly.

* Attention should be paid to preserve traditional landscapes and the diversity of nature. Asphalted surfaces should be avoided and space should be saved for plants.

* Traffic noise and other problems caused by traffic should be reduced as much as possible.

* Campsite operators and users should make use of local products and services as far as possible.

* Campsite operators and users should act in every aspect in accordance with the principles of sustainable camping.

* Sustainable camping includes the use of public transport as far as possible.

* Hiking and biking are examples of environmentally friendly exercise.

* In nature we campers should stick to trails. Nature programs should be designed so that they use existing trails and routes. The goal of guided nature trips should be to improve our knowledge of the environment and awareness of the nature.

* We should regulate our water consumption as well as the use of lighting and heating energy. Use of electric hand dryers etc. should be avoided.

* Use of environmentally harmful products as disposable plates, mug, toilet articles, etc. should be avoided. Also we should avoid of use of canned drinks and drinks in plastic bottles in favor of glass bottles.

* Also we campers should take care of sorting the waste. Lubricants and other problem waste should be sent to enterprises qualified to dispose of them. Organic waste should became composted and all waste should be removed from the nature.

Green Living Tips


Do you care about the environment and your health, but want to be stylish with your home décor at the same time? Luckily, there are plenty of green living options that can be implemented in your home in order to create a great look while remaining eco-friendly.

Making Sustainable Choices

Making sustainable choices are an important component of green living. Making sustainable choices means purchasing products that don’t cause a negative impact on the environment and that will not make it more difficult for future generations to continue to sustain themselves. Making sustainable choices during the design process is referred to as 'green design' or 'sustainable design'. Some great sustainable choices to consider when decorating include:

• Natural stone counter tops
• Cabinets and other products made from woods such as bamboo, eucalyptus, or recycled wood
• Carpet made from natural fibers, such as wool and cotton, or made from recycled materials
• Green-friendly paint and home wallpaper, which is being offered by a growing number of manufacturers
• Antiques – after all, they are being recycled!

You don’t have to create a bland and boring home décor in order to enjoy green living. In fact, there are numerous options out there that will allow you to make your home look great while still protecting the planet.

Appliances for Green Living

When it comes to green living, a great place to start is in your kitchen. Remodeling can add a great deal of value to your home, can make it more functional and attractive, and can help you make your home more eco-friendly.

When buying for your kitchen, look for modern appliances to help bring your home up-to-date. By purchasing those appliances with the Energy Star rating, you can potentially cut the amount of energy you use to power those appliances in half. Adding faucet aerators to your kitchen and bathroom faucets will also help reduce the amount of water you use while still providing you with a high pressure stream of water.

Obtaining Green Products

Fortunately, green living is rapidly growing in popularity. In response, many manufacturers are offering lines of eco friendly products that can be used for decorating purposes. In addition, a growing number of online and offline stores that are dedicated solely to green living are becoming a more common occurrence.

Although it may take a little more time and effort to find and purchase eco products for your home, the effort will be worth it. Not only will you be doing your part to help conserve and protect the environment, green living is better for your health and can save you money in the long run.

What Everyone Should Know About Renewable Energy


It has long been observed and proven that nature has already provided man with enough resources for energy—sunlight, geothermal heat, tides, and wind. Because these energy are abundant, in fact, so abundant that they could be replenished perpetually, they have come to be known as renewable energy.

Though extended discussions about renewable energy and its sources can become winded and more complex, every average person interested enough should at least know the basics in order to grasp the concept of how incredibly beneficial these energy sources are.

Man has long harnessed the power of wind and had applied it for practical purposes, albeit in smaller scale such as the power produced in windmills. Current technologies had long converted these simple renewable energy mechanisms to develop wind farms that generate energy supply without the associated risk of pollution
. A lot of wind farms have been established in the United States and abroad to generate electricity. This provides proof on the increasing attraction of using wind power as source of renewable energy while decreasing environment risks and hazards. One critical consideration in establishing wind farms would the presence of constant strong winds, which is why many wind farms are located in elevated areas and even offshore locations are considered viable settings for this kind of renewable energy facility.

Renewable energy from water comes in many different forms. The most common would be the hydroelectric energy that is generated by waterfalls while some areas of the world also generate micro hydro systems that produce smaller amounts of electricity. Renewable energy is also tapped from currents deep under the ocean. This is termed as tidal stream power and several technologies have been developed to harness these viable source. Other sources of renewable energy generated from oceans would be tidal changes, temperature difference, tidal motions, and of course, waves.

Another viable renewable energy source is sunlight, which earth certainly has in abundance. There are numerous technologies developed to tap the solar energy and convert it into electricity, heating systems, and even cooling systems. Though most of these technologies are still in the initial stages, there is no denying the potential benefits promised by this renewable energy source. One of the leading concerns is cost of the materials used, though several affordable yet more efficient designs are still expected to be introduced into the market.

A lot of geothermal power plants had been built and have long been operational in several parts of the world. This is because this source of renewable source of energy generates power at low operating cost. Though some experts may contend that geothermal energy would not last as long as the others and is technically not renewable, it is still expected to provide large amount of power for a long time, even for a hundred years or so. However, it is still classified as a renewable energy source by the International Energy Agency and, like all other sources mentioned above, geothermal energy is reliable and environmentally friendly.

Though none of the renewable energy sources are considered to compete with fossil fuels just yet, it still provide some form of alternative for environmentally conscious individuals and communities in doing their share of lessening environmental degradation and destruction, something we can all ultimately derive benefits from.

Is There A Pattern Forming Here?


"Green Building" is a broad term used to describe the design and construction of sustainable and environmentally conscious buildings.

The driving force behind this is to lower our negative impact on the environment and, at the same time, make the buildings we live and work in safer and healthier for us.

According to the United States Green Building Council (USGBC) statistics,`buildings are responsible for all of the following:

* 39% of US carbon dioxide (CO2) emissions

* 70% of US electricity consumption

* 15 trillion gallons of water consumption



Even though there is still some controversy over the effect of greenhouse gases on the environment, the last two statistics are very important for those of us living in urban areas experiencing continuous growth, especially the American Southwest. With our population expansion, aging water and electrical infrastructure, and shrinking landfills, designing and constructing green and sustainable buildings makes practical sense from a utilitarian perspective.

In fact, USGBC data shows that green buildings use 36% less energy, require fewer raw materials, and divert less waste to our landfills. Furthermore, the "increased" cost of green building is only one or two percent more expensive than a conventional building. This minute difference exemplifies the tangible and long-term benefits of sustainable design, primarily due to the fact that green buildings conserve water and electricity. Thus, while they are more expensive to build, green structures will save money by conserving more energy over time.

Another push towards the green build movement is by local governments. More and more municipalities
are adopting the USGBC LEED® (Leadership in Energy and Environmental Design) guidelines for new
and renovated buildings. In 2006, at the USGBC Greenbuild expo, the Mayor of Denver challenged other major cities to see who can have the most LEED® certified green buildings. They are accomplishing this by offering tax breaks to private corporations and mandating sustainable construction for city-financed projects.

This has led to a dramatic increase in the number of sustainable projects built by LEED® Certified general contractors. However, this growth has not come without challenges. Currently, the following issues are restricting the number of green projects being built:

* Increased demand for green products has lead to long lead times

* New and unspecified materials are labeled “green” products which are not necessarily certified

* Building officials are struggling with a steep learning curve on how to evaluate these new products and sustainable building techniques



Despite these difficulties, the USGBC, sustainability advocates, and green building construction management firms are meeting to overcome these challenges.

The LEED® process is constantly under review and continues to adopt the latest codes and products. This includes Standard 189, a new minimum standard for green building. The USGBC is currently developing LEED® 3.0 and working with national code writers to include new products and techniques.

The American Institute of Architects (AIA) has even rolled out a new initiative called "Sustainability 2030," which at its roots, is looking to design all buildings by the year 2030 as carbon neutral. The USGBC has even initiated the Green Advantage Builders Certification for contractors to certify their knowledge in green building
techniques.

So what does green building mean at the end of the day? It's simple yet profound: Do the right thing for you, the environment, and the next generation. While most companies are concerned with their bottom line, they ought to embrace the idea that energy and water conservation, green building, and the use of "green materials" in construction stands to increase their savings over time while positioning them as a leader in environmental stewardship.

According to the USGBC, we spend 90% of our time indoors. Due to this fact, scientists have identified an increase in allergies, asthma, absenteeism from school, and even work. There have been numerous studies done on post occupancy productivity levels, which have increased within "green" built facilities. Not only does
green adaptation result in less sick days taken, but also shows an increase in productivity, job
satisfaction, and in the case of schools, better grades.

Listen To The Wind


Wind generators are one of the most reliable forms of alternative power sources on the planet.

They manufacture power by transforming the kinetic energy of the wind into mechanical energy.

This energy is then either harnessed directly (in the case of windmills, for example, which were once used to change wheat into flour, or to pump water for farming) or coupled to a generator that creates a direct current that can be used in a more general sense.

In this article I will be talking about the type of wind generators that produce electric energy, as this is more useful to us in our daily lives.

Wind turbines are basically large windmills, with gigantic blades that rotate in the wind and produce power from the conversion of the wind’s force. Wind turbines are made of plastic, aluminum, steel and numerous other space-age metals.

Wind turbines do have a few negative effects on the environment.

One such negative effect is sight pollution. Wind turbines are very visible and quite unsightly because they must be put in proximity to windy, open terrain to be useful.

Wind turbines also require a great deal of energy in their manufacture. This energy is typically fossil-based, and it can take up to five years before wind tunnels are positive in terms of total carbon emissions.

Wind turbines also are linked to the mauling of rare species of birds. Birds have been mutilated as they passed through the turbine fans during migration.

Despite all of the downsides, however, wind turbines should be a choice when talking about a broad plan for renewable energy.

Once erected, wind turbines are amazingly efficient in a larger sense. They generate power from a natural, eco-friendly renewable resource, without the hidden social or environmental penalties that we incur with the use of fossil fuels.

There is no need to mine for fuel or to transport it; there are no global warming pollutants created and no need to store, process or dispose of toxic wastes.

At the low end of the scale, turbines can be as tiny as 5 feet in diameter and are capable of only a few hundred watts.

On the high end of the spectrum, turbines can be as big as 300 feet in diameter and are capable of generating two to five megawatts of power.

As with photovoltaic solar power generation, there might be rebates available for construction of wind turbines, and excess energy can be sold back to the power company.

Wind velocity is affected by topography and increases with height above the ground, so wind turbines are generally installed on top of large towers.

In a typical application, the wind turbine sits on top of a tall tower and generates low voltage direct current, which is used to charge a battery store.

This stored potential energy is ultimately used by routing it through an inverter that changes the low voltage direct current power into an alternating current that can be used in household applications.

By concentrating a substantial number of turbines into wind farms, a substantial amount of electricity can be stored and used, perhaps, for an entire city.

Because the wind doesn’t blow all of the time in many areas, wind turbines are used as adjuncts in hybrid configurations with many different technologies – photovoltaic panels and diesel generators, to name two – to provide a consistent source of electricity.

Unlike fossil-fuel stations, wind turbines are clean and green. They don’t create the carbon dioxide emissions that are causing greenhouse gases or the acidic emissions that cause acid rain.

Today’s turbines are divided into 2 categories: horizontal turbines and vertical turbines.

Horizontal axis wind turbines are actually far better at capturing the wind than vertical axis turbines given the same amount of swept area (which is the diameter of the circle traced by the outside tip of the rotor blades).

Although the public application of wind power has gotten widespread attention, there potentially is an even better use of this gift from Mother Nature, better than the massive wind farms you see on TV.

In fact, this alternate use of wind power could be a financial windfall for you.

Picking a Sustainable Yoga Mat


It does not matter whether you are a yoga newbie or have been doing yoga so long you've memorized your instructor's routine, asana-by-asana - sooner or later you'll be in the market for a new yoga mat. I used to think every yoga mat was created equally until I bought a jute yoga mat and discovered that it didn't smell like chemicals. Of course, it fell apart within two months...

That's when I decided to write an article about the different types of yoga mats out there, how to choose one that's best for you, and how to choose one that isn't terrible for the environment either.

The Standard Cheap Yoga Mat

Many people get a cheapo mat the first time. This is fine, especially if you're not sure whether you are going to be a yoga fanatic yet. You can usually find these from between $5 and $10 at any mega-store like Target or Kmart.

There are several problems with a standard yoga mat. First, they are often very thin and do not provide much cushioning. Most importantly, however, they stink like chemicals and are made using a very environmentally hazardous process. Furthermore, the chemicals used may be bad for your health. They are made using phthalates, which turn hard plastics into soft plastics. Studies on rodents involving large amounts of phthalates have shown damage to the liver, the kidneys, the lungs and the developing testes.

I know a lot of people who use standard yoga mats and they're not dead or dying (that I know of). Just don't leave them in the trunk of your car because they tend to release a chemical smell when they get hot.

Jute and Cork Yoga Mats

Jute and cork yoga mats are an affordable, eco-friendly alternative to the standard yoga mat, but they have some drawbacks of their own. Cork and jute mats both come from very porous plants. As the material absorbs your sweat during yoga classes, it becomes A: a bit stinky and B: a little weak. While it is not going to fall apart in your hands like wet paper, don't expect one of these to last a long time if you do yoga more than once a month.

Rubber Yoga Mats

Rubber yoga mats are my favorite. They are durable, affordable and - best of all - they are made from rubber, which is a fairly sustainable material that comes from the rubber tree. Just make sure that you are buying a "natural" rubber mat because the material can be produced synthetically as well - although synthetic rubber isn't nearly as bad for the environment and your health as phthalates.

Natural rubber yoga mats should be avoided if you are allergic to latex. Instead, try one of the phthalate-free, latex free mats from this page http://www.gaiam.com/retail/product/95-1041_OLIV . They are a little more expensive, but if you are allergic to latex, don't want to work out on chemicals, and need something that isn't going to fall apart on you - this type of mat is definitely the way to go.

Using a Pilates Mat for Yoga

Pilates mats are much thicker than yoga mats. This is required because you are spending more time on the floor, often with pressure points like hips, knees, shoulders and elbows supporting some or all of your weight. It is also very important for cushioning to keep your spine from getting injured when doing rolls while lying on your back. Can you use a pilates mat for yoga? Sure, but they are more expensive, bulkier, and you will need to make sure they have a non-slip surface. Yoga mats do tend to be "stickier" which is needed when doing most asanas. But if you do yoga and pilates, try buying just the pilates mat and see if you like it for yoga as well. I do not, however, advise using a yoga mat for pilates, as it can cause injury.

Places to find yoga mats online:

http://www.gaiam.com/yoga/ - Gaiam Yoga Products are well known for their quality and for including many eco-conscious options like jute and rubber. The can be a little pricey, but if you look for items on sale there are deals to be found.

http://www.ecomall.com/biz/fitness.htm - Eco Mall's yoga and fitness section has a huge list of online resources, most of which have a "green" outlook on business.

http://www.firstpagefitness.com/directory/ - First Page Fitness has a directory of businesses in the fitness industry, many of which sell yoga mats online.

http://www.target.com - Target has a lot of inexpensive yoga products, including a few different types of standard yoga and pilates mats. If your goal is to just buy something cheap to get started with, I'd advise skipping all of the expensive shops and just going to Target.

Using the Class Yoga Mats

I strongly discourage using the communal yoga mats found in most fitness centers and studios. These are breeding grounds for germs and bacteria. You can buy yoga mat wipes if you must use a communal mat. Most of these wipes are just expensively packaged alcohol pads, so you can save a lot of money by getting a box of wipes from Walgreens.

Going Without a Yoga Mat

People have been practicing yoga for thousands of years without modern mats. The reason why most people these days use a yoga mat is because they wear socks, which cause their feet to slip during poses. Even if they do their yoga routine without socks (which can be very unhygienic in most fitness centers and yoga studios) today's yoga routine typically takes place on a tile or hard-wood floor, which becomes slippery as the feet sweat. Thus, a sticky yoga mat provides the necessary foundation on which to perform the asanas. However, if you regularly practice in an environment that does not have a slippery surface - such as outdoors or on carpet - there really is no need for a yoga mat at all. I have also found that a pair of yoga socks like these - http://www.gaiam.com/retail/product/95-9196_MSTR - works just as well as a mat without all of the hassle and a fraction of the cost.

Whether you go with a standard mat, a Pilates mat, socks, or one of the many "green" options available these days, there is a yoga mat made just for you! I hope the above information helps you decide.
