About Earth Day Network
The first Earth Day, on April 22, 1970, activated 20 million Americans from all walks of life and is widely credited with launching the modern environmental movement. The passage of the landmark Clean Air Act, Clean Water Act, Endangered Species Act and many other groundbreaking environmental laws soon followed. Growing out of the first Earth Day, Earth Day Network (EDN) works with over 22,000 partners in 192 countries to broaden, diversify and mobilize the environmental movement. More than 1 billion people now participate in Earth Day activities each year, making it the largest civic observance in the world.
But Earth Day Network does not stop there.
All of EDN’s activities, whether greening schools or promoting green economic policies at home and abroad, inform and energize populations so they will act to secure a healthy future for themselves and their children. With its partner organizations, EDN provides civic engagement opportunities at the local, state, national and global levels. At every turn, EDN works to broaden the definition of "environment" to include all issues that affect our health, our communities and our environment, such as greening deteriorated schools, creating green jobs and investment, and promoting activism to stop air and water pollution.
Over the last 40 years, EDN has executed successful environmental campaigns on issues ranging climate change and drinking water to voter registration and saving the whale. EDN is a recognized leader in creating civically–oriented innovative programs with partners outside of the environmental movement to tackle new challenges. Our core programs today focus on:
A Guide to Lighting your Home with Solar Energy
Jan 07, 2014 by Wendy Weinert
Solar energy is fast becoming the most cost-effective and realistic alternative to conventional energy production. In residential capacities, solar energy systems harness energy and heat from the sun, converting it in order to power your lights, hot water heater, appliances, and more. There are numerous types of solar energy systems, and the benefits of incorporating this environmentally friendly resource into your home are astonishing. From reducing the impact that you have on the environment to cutting your utility bills and upping your resale value, solar energy is truly a worthwhile investment.
Solar energy utilizes the natural resources of the sun to generate heat and electricity. Systems come in various sizes, from just a few panels to light your home to larger systems that essentially take you off of the grid. Most residential applications work via photovoltaic cells, which absorb light and then transfer it to a semiconductor, freeing up electrons and generating a current. The current is then fed into your home, powering everything from your table lamp to major appliances. It can also be fed directly back into the power system you're already hooked up to, sending it to the utility company as an energy surplus. Solar energy is considered an intermittent source, simply because cloud cover eliminates the availability of sunlight, halting the process. However, residential solar energy systems often come equipped with a storage feature, creating a back-up when the weather doesn't cooperate.
The 11th International Conference & Exhibition on Emissions Monitoring (CEM) 2014
CEM 2014 The 11th International Conference and exhibition on Emissions monitoring will take place in Turkey in the country’s capital, Istanbul, from the 14th – 16th May 2014.
Since its inaugural meeting in 1997 the CEM conferences have been held in the United Kingdom, The Netherlands, Denmark, France, Italy, The Czech Republic and now it comes to the historic city of Istanbul where East meets West.The CEM event brings together the International emissions monitoring community to network, trade ideas and discuss technology, methods, applications, legislation and standardisation relevant to all atmospheric pollutants which include particulates, SO2, NOx VOC, trace elements and greenhouse gases.
The Turkish economy has experienced annual economic growth rates of nearly 10% for the last couple of years and this has increased the wealth of the country, and its people. The growth has been driven by Western Europe outsourcing manufacturing to Turkey instead of China and the main drivers have been lead times and quality of products.
Turkey prides itself on being everyone’s friend and as well as a great market in itself, Turkey also makes a great location to launch into the Middle East Region.

In the United States, most households could benefit from conserving energy. By reducing energy use they also reduce greenhouse emissions and positively impact the environment. Families will also see the positive impact of their actions in terms of their finances. On average, people can save almost $2,000 annually on the energy that they spend in their homes. In households that actively take steps to be more energy-efficient, energy bills may be as much as 40 percent lower than other homes. The impact that energy has on a typical family's finances is often a motivating factor in the decision to develop a plan to conserve energy.
In order to develop the most effective plan, it must first be determined what areas in the house are using excess energy. To accomplish this, an inspection of the home is necessary. When checking the house for areas of energy loss, start by closing off all windows, doors or anything that leads outside of the home. Shut off water heaters and gas appliances, and then turn on the exhaust fans and floor and window fans. To test for drafts, a person may use a dampened hand, a lit incense stick or a lit candle. In each room, hold the damp hand, candle or incense up to cracks, baseboards, outlets, attic hatches, doors, windows, and room corners. If there is a draft, it will make a damp hand feel cold. When using incense or a candle, a draft will cause the smoke to move. Once these draft areas have been identified, create a list of which areas are the most inefficient and the most costly in terms of energy lost. To make energy improvements, start at the top of the list and work down.
Dear friends from Ecovillages worldwide,
I want to inform you about our Third Water Symposium in Tamera.
Water is a topic for everybody on this planet - and for sure for every ecovillage. Many ecovillages face severe challenges like salizination of ground water, treatment of sewage water, clean drinking water, and water for agriculture. Other challenges are the privatization of water, big dams and laws that in many cases support rather industry and centralization than decentralized models.
And many ecovillage have worked on regional solutions, sometimes they created model solutions that can and should be shared with others to help each others.
For this we organize this Water Symposium. Read more below. And please spread this information to all those who may be interested.

Water management in Europe faces rising challenges as ecosystems weaken
Water pollution and excessive water use are still harming ecosystems, which are indispensable to Europe’s food, energy, and water supplies. To maintain water ecosystems, farming, planning, energy and transport sectors need to actively engage in managing water within sustainable limits.
Water is finite, and cannot continue to absorb limitless amounts of pollution without damaging the resources and ecosystems we rely on.
Jacqueline McGlade, EEA Executive Director
‘European waters – current status and future challenges’ brings together findings from nine other European Environment Agency (EEA) reports published during the course of 2012 and early 2013. The report shows a mixed picture for the status of Europe’s water bodies, while the findings are worrying when it comes to ecosystems' ability to deliver essential services.
Strong ecosystems should be maintained, partly because they provide vital services which are often overlooked, the report says. For example, restoring a wetland is not only good for biodiversity but also water filtration, water retention and flood prevention. Although essential, these services are not accounted for in current financial and economic systems.
“Water is finite, and cannot continue to absorb limitless amounts of pollution without damaging the resources and ecosystems we rely on,” Jacqueline McGlade, EEA Executive Director, said. “Farmers, planners and companies need to cooperate more, to make sure that the combined pressures on ecosystems do not pass harmful limits.”
"Climate Conference in Doha to lead us into a dangerous impasse"
Coalition of the willing instead of waiting for consensus – climate bailout fund needs to be implemented quickly
Statement by Dr. Thiemo Gropp, Director of the DESERTEC Foundation, on the climate conference in Doha (Qatar)
Hamburg 27th November, 2012. For the 18th UN Climate Change Conference around 20,000 people from over 190 countries have boarded planes to stay in air-conditioned hotels and produce huge amounts of CO2 all in the name of climate protection. And what is the result of almost two decades of this annual meeting? The world emits more CO2 today than ever before.
Climate protection is a global issue that cannot be solved by one country alone. But the premise of the UN climate conference that the start of comprehensive climate action must depend on the global consensus of all concerned parties brings us to a dangerous impasse. As long as countries believe that further negotiation can bring them economic advantages there will always be delay. What we need is a coalition of the willing committed to funding solutions from which all parties will benefit.

The zero fossil energy consumption principle is gaining considerable interest as renewable energy harvesting is a means to cut greenhouse gas emissions. Traditional building use consumes 40% of the total fossil energy in the US and European Union. In developing countries many people have to live in zero-energy buildings out of necessity. Many people live in huts, yurts, tents and caves exposed to temperature extremes and without access to electricity. These conditions and the limited size of living quarters would be considered uncomfortable in the developed countries.
The modern evolution of zero-energy buildings
The development of modern zero-energy buildings became possible not only through the progress made in new construction technologies and techniques, but it has also been significantly improved by academic research on traditional and experimental buildings, which collected precise energy performance data. Today's advanced computer models can show the efficacy of engineering design decisions.
Energy use can be measured in different ways (relating to cost, energy, or carbon emissions) and, irrespective of the definition used, different views are taken on the relative importance of energy harvest and energy conservation to achieve a net energy balance. Although zero energy buildings remain uncommon in developed countries, they are gaining in importance and popularity. The zero-energy approach has potential to reduce carbon emissions, and reduce dependence on fossil fuels. Most ZEB definitions do not include the emissions generated in the construction of the building and the embodied energy of the structure. So much energy is used in the construction of a new building that this can dwarf the operational energy savings over its useful life.
A building approaching net zero-energy use may be called a near-zero energy building or ultra-low energy house. Buildings that produce a surplus of energy during a portion of the year may be known as energy-plus buildings.
If the building is located in an area that requires heating or cooling throughout parts of the year, it is easier to achieve net zero-energy consumption when the available living space is kept small.
Despite sharing the name zero energy building, there are several definitions of what ZEB means in practice, with a particular difference in usage between North America and Europe.
- Net zero site energy use
- In this type of ZEB, the amount of energy provided by on-site renewable energy sources is equal to the amount of energy used by the building. In the United States, “zero energy building” generally refers to this type of building.
- Net zero source energy use
- This ZEB generates the same amount of energy as is used, including the energy used to transport the energy to the building. This type accounts for losses during electricity transmission. These ZEBs must generate more electricity than net zero site energy buildings.
- Net zero energy emissions
- Outside the United States and Canada, a ZEB is generally defined as one with zero net energy emissions, also known as a zero carbon building or zero emissions building. Under this definition the carbon emissions generated from on-site or off-site fossil fuel use are balanced by the amount of on-site renewable energy production. Other definitions include not only the carbon emissions generated by the building in use, but also those generated in the construction of the building and the embodied energy of the structure. Others debate whether the carbon emissions of commuting to and from the building should also be included in the calculation.
- Net zero cost
- In this type of building, the cost of purchasing energy is balanced by income from sales of electricity to the grid of electricity generated on-site. Such a status depends on how a utility credits net electricity generation and the utility rate structure the building uses.
- Net off-site zero energy use
- A building may be considered a ZEB if 100% of the energy it purchases comes from renewable energy sources, even if the energy is generated off the site.
- Off-the-grid buildings are stand-alone ZEBs that are not connected to an off-site energy utility facility. They require distributed renewable energy generation and energy storage capability (for when the sun is not shining, wind is not blowing, etc). An energy autarkic house is a building concept where the balance of the own energy consumption and production can be made on an hourly or even smaller basis. Energy autarkic houses can be taken off-the-grid.
