Can you recognize that the igloo in this picture was built from 322 fridges in Hamburg? It is titled “Wastefulness is the biggest source of Energy”. The picture was taken by Moritz Bappert. The igloo is an art project by Berlin-based artist Ralf Schmerberg and is supported by an energy provider.
The artist vividly used a huge electricity meter to demonstrate how much energy could be saved if all of the old fridges were replaced with modern ones. The loud message sent is that “Waste is the biggest resource.” According to the Canadian Government, the refrigerator is the 3rd heaviest consumer of power amongst household appliances. If you have an old fridge, it is time to buy a new energy efficient fridge.
Tips to buy a new fridge:
- Look for the ENERGY STAR symbol
- The lowest EnerGuide energy consumption rating
- An “Energy Save” switch that controls heating coils in the cabinet (they prevent condensation in humid weather, but you should turn them off when the air is dry)
- Separate temperature controls that regulate the inside temperature of the refrigerator and freezer compartments
- Easy-rolling wheels, which make cleaning easier, especially for vacuuming the condenser coils regularly in order to maximize efficiency and compressor life
As residential solar panels are gradually entering into average household, you may wonder whether the investment is worthwhile. Let’s find it out!
Since the need to come up with some very reliable “green energy”sources has become more than stringent, the market for residential solar panels has registered a massive extent over the last years. Solar light and heat are free, available all year round and totally environment-friendly; therefore, the systems that capture and redirect such energy are more than preferable to other thermo solutions. Residential solar panels cover the needs for both heat and electricity depending on the type of system you have installed, meaning that you’ll have all the energy necessary for the house appliances without paying for it every month.
When you have some residential solar panels installed on your roof, you don’t have to know all the scientific details that make them work in the most efficient of ways. You just have to enjoy the advantages of a good electric system that is completely silent, highly clean and always renewable. For the moment, residential solar panels are considered the energy source of the future in the condition of an ever more reduced fuel supply and given the harmful impact of toxic emissions on the environment. The panels are organized in modules that rely on cells in their turn, generating DC electricity.
The additional devices necessary for the use of residential solar panels include an inverter and a storage battery with a charge controller. The later piece of equipment is the one that prevents overcharging, and it is often considered a must-have element for a complete and safe system installation. The inverter is necessary for the transformation of the direct current (DC) into alternative current (AC) since this is the form used by home utilities. Before purchasing an inverter for the residential solar panels it is good to check its performance in terms of operation specificity.
The amount of electricity that you can expect the alternative-energy system to produce on a daily basis depends on the number of residential solar panels installed. Moreover, the extent of the system is also determined by the kind of weather specific to the geographical area you inhabit. In winter months, additional solar panels may be necessary, which explains why in warm areas of the globe home users rely on fewer residential solar panels with a high efficiency level. If you manage to cover at least 80% of the needs of your household, you can truly consider that you’ve made a great investment.
Across the Internet, people are reading about Greenpeace’s criticisms of Apple’s reliance on coal, floating wind turbines for deep-sea wind farms, and some cool new smart grid projects happening around the world. Read all about it.1. “The Competitive Advantage of Green Grids” – Mother Nature Network – MNN takes a look at green power grids, which use everything from geothermal (in Iceland), to solar and wind power (at a Walmart food distribution center in Calgary, Alberta) are not only cleaner, but are an attractive business opportunity. This reflection comes in the wake of the Greenpeace demonstrations at Apple stores across North America, where activists criticized the company’s reliance on coal power.
2. “Massive Offshore Wind Turbines to Float in Waters Over a Thousand Feet Deep” – ARS Technica – Last week, the US and UK announced that they would be jointly researching and funding projects to construct floating wind turbines for deep-sea wind farms, and the U.S. Department of Energy has pledged $180 million for this endeavor. However, there is some concern about the countries’ ability to fund a floating wind farm, as these turbines are notoriously expensive to build and install.
3. “6 Smart Grid Projects You Don’t See Every Day” – Smart Grid News – A look at six of the more unusual advances in smart grid technology found around the world, from using the otherwised unused “white space” of the wireless spectrum for green apps in Cambridge, England, to solar-powered microgrids in rural India, to the revamping of an old hydroelectric plant for a clean microgrid in southern Michigan. These projects all seek to provide clean and cost-effective energy to people in all walks of life on a local scale.
4. “Renewable Energy Generation is Big Business in Kenya” – Renewable Energy World – Companies in Kenya, including sugar and tea companies, are getting into the business of being IPPs–independent power producers–by using biomass, wind and solar powers, along with energy storage technologies, to generate power. The power is then sold to the national grid, and the money is used to benefit the company as well as its workers. Because of increased energy demand, Kenya is also planning a 300-megawatt wind farm in the Ngong hills forest.
5. “Vauxhall Predicts Ampera Will Boost Electric Car Sales” – The Guardian – The Vauxhall Ampera, known stateside as the Chevy Volt, was introduced as a solution to the “range anxiety,” or the fear of a battery-powered car running out of juice on a long trip, many potential consumers voice. Despite sluggish sales last year, the Ampera is predicted to sell well in Europe this year, and automakers have been stressing the fact that when, after 50 miles of purely electric power, the battery runs out, the gas engine seamlessly takes over, protecting against breakdowns.
Do you think that global warming is too far away from your personal life? No, it may not. While I was doing research on global warming today, I came across Shoshana Zuboff story on how global warming turned her peaceful life upside down. Here is Shoshana’s story. It may change how you think about global warming and how you conduct your daily activities.
Fifteen years earlier my husband and I gave up fame and fortune to raise our son and daughter on a Maine farm. We wanted them to grow up with the respectful down-to-earth values of our small Maine town. We hoped they would shape deeply lived authentic lives surrounded by natural beauty and bound to the rhythms of the seasons. Our life was a celebration of long Huck Finn summers and cozy snowy winters. We created an 18th century household filled with books, music, and memories in which we all worked and played. It was our sanctuary — the safest, happiest place on earth. Later our children taught us to be green. We installed windmills and solar panels, recycled and composted, and became more mindful of our footprint. Still, we felt safe from the worst ravages of global warming in our bucolic corner of the “first” world here in New England. The real catastrophes were “out there” in sub-Saharan Africa, Bangladesh, the Andes or tiny Pacific islands. Then global warming crashed our party in paradise.
That night I thrilled to the thunderstorm raging outside. Then a bolt of lightning crashed through the kitchen window, mowed me down like a freight train hurtling through my chest and triggered a blast so loud I thought the sound barrier had been breached somewhere between the crockery and the curtains. When I opened my eyes, I was lying on the floor. Then came smoke. Fifteen minutes later we were out in the storm, watching in disbelief as our beloved home vanished in a towering wall of flame.
I am not a climate change scientist, but I have come to understand that I am a climate change victim. Our daughter took the lead investigating destructive lightning in Maine. She found that the NASA Goddard Institute estimates a 5-6% change in global lightning frequencies for every 1 degree Celsius global warming. The Earth has already warmed .8 degrees Celsius since 1802 and is expected to warm another 1.1-6.4 degrees by the end of the century. Maine’s temperatures rose 1.9 degrees Celsius in the last century and another 2.24 degree rise is projected by 2104. I learned from our insurance company that while the typical thunderstorm produces around 100 lightning strikes, there were 217 strikes around our house that night. I was shocked to discover that when it comes to increased lightning frequency and destructiveness, a NASA study concluded that eastern areas of North America like Maine are especially vulnerable. Scientists confirm a 10% increase in the incidence of extreme weather events in our region since 1949.
Was the lightning bolt in our kitchen caused by global warming? The facts are too compelling to ignore. It seems that global warming turned my family into refugees in our own lives, stripped of everything that once carried our memories and meaning. Since then I’ve learned some lessons that may help others reckon with the realities of climate change and the terrifying prospect that our future will be different from our past.

Climate change is not a blip but an epochal shift, yet we seem unable to do much more than close the doors to rooms bound for extinction. Are we in a countdown to a hell time of irreversible loss or to a renaissance of invention and adaptation? It depends on how we learn to pivot. Every level of the system — from each person to the governments of the world — can learn to understand and confront the error of predictability. Naming it and identifying its consequences is a start. Then let’s learn how to teach our children, our leaders and ourselves what it means to live without terror in the knowledge that our planet is spinning on a new course.
Shoshana’s story is very compelling. To save our planet and save our children from the natural disasters such as drought, tornadoes, hurricanes, earthquakes, etc caused by global warming, each one of us need to be conscious about the effects of global warming and take actions to stop global warming.
Global warming is the fact of life that many of us need to deal with. In order to know more about how global warming has come into effect you need to know the reasons for this greenhouse effect. While there are many causes which have given rise to global warming, the main cause of global warming is humans.
While you may not feel that this fact is true when you look at how we treat the environment and the pollution that we have heaped on the earth. You can then gain an inkling of the reasons for global warming.
The first place to look for the main cause of global warming is in our cities. The work, which we do in the cities in order to live comfortably, helps to cause this greenhouse effect. The main culprits for global warming in our cities are cars and industries. You can see just from walking or driving around how many cars travel to and fro in the streets.
Each of these cars produces carbon as a waste byproduct. This chemical is then sent out into the atmosphere where it gathers with other atmospheric chemicals. These chemical substances travel to the upper part of the atmosphere and here they form a sort of umbrella over the earth.
This is where the term greenhouse effect has come into play. Of course cars are not the only main cause of global warming. You will find that the smoking chimney stacks from older industries send up huge amounts of smoke into the air. While some of this smoke is harmless there are others which are not that harmless.
These more dangerous smoke particles interact with the clouds and the other molecules in the atmosphere. The resulting winds, rain and fog which you see causing havoc with our lives are the effects that you can see from global warming.
Another item that you need to understand is that with the massive amounts of deforestation that we are causing, the amount of life giving rain is reduced. The forests where these trees are located are not able to process the amounts of carbon which is found in the air. As the deforestation is caused by our need for land, timber and plants we are in fact the main cause of global warming and environmental pollution with regards to deforestation.
While there are some people who will disagree the fact that humans are the main cause of global warming, there is ample evidence to support this fact. If you are prepared to stop global warming from becoming even worse then you need to accept your part in the trend of global warming.
As we are the main cause of global warming, we need to work together all over the world to stop the causes and effects of global warming from destroying the world that we live in. Here are some steps you can take to stop global warming:
- Use energy efficiency bulbs
- Do more recycling
- Avoid products with lots of packaging
- Adjust the thermostat to save cooling and heating cost
- Use public transit whenever possible
- Plant trees and grasses
