    DESERTEC project, Sahara Sun could power Europe by 2050

    By Mark Piazzalunga

    Sahara desert climate is hot and arid, everybody knows it. So how can this simple and well-known fact become the idea to power a continent like Europe? Let’s start from the principle: renewable energy is the future of energy; we assume that this sentence is true since all facts gets to this point. Second principle: European territory is restricted and allows the construction of a few plants that could use renewable energy. Paradoxically, countries like Africa have renewable sources, particularly solar, in abundance but scarce funds to make the best of these resources. Now find the connection. Is it possible to produce huge amounts of solar energy in Africa and transport them to Europe through energy infrastructures? Apparently yes, according to DESERTEC project developers and supporters. And what is DESERTEC? It’s an initiative of the Club of Rome (a global think tank that has its headquarters in Switzerland) started in 2009. Directly from the official website of the project (Desertec.org): "The DESERTEC concept was developed by a network of politicians, scientists and economists from around the Mediterranean, from which was born the DESERTEC Foundation. Demonstrates a way to provide climate protection, energy security and the development of sustainable energy generation from sites where renewable energy sources are at their most plentiful." In practical terms? Connect renewable energy power plants in Africa to Europe through a network of HVDC (High Voltage Direct Current) systems. The Foundation target is to build several renewable power plants of various types (mainly wind, photovoltaic and solar concentration) throughout North Africa. To support the project financially, the Foundation and other 12 companies (including Deutsche Bank, E.ON, RWE and ABB) created an industrial initiative: Dii GmbH. The construction project would continue until 2050 and for that date, the cost is estimated at € 400 billion, which means $ 546,720,000,000, approximately seven times Bill Gates’ fortune. It’s little bit expensive (life on Mars seems cheaper) but the entire network could provide Europe with the 15-20% of electricity that it needs. We must also consider the drastic decrease of pollution, direct effect of the project. This project isn’t just an idea but it seems an accurate and long-term plan. This could be an opportunity to connect two continents and to give them economic opportunities and jobs. There could be some problems like the wars and the instability of some of North Africa countries or how to get all 40 nations to agree to an arrangement for subsidizing the green electricity. There’s also the possibility to build the plants in Europe, just $ 54 billion more, and doing some math it brings to a shocking number: €2 per citizen per year to keep tens of thousands of jobs in Europe -- and to prevent Europe from becoming dependent on foreign countries for its electricity. Well, the project just started and it has the funds to go forward. We can't wait to see the results. Photo from Desertec.org

    Conferencing Climate Change: Teamwork or Tug-of-war?

    By Megan Bonetti

    India. Culture, cows and rubbish. As an Aussie living for a short time in India it is such an intriguing country. Indians love their diverse nation yet they use the streets like rubbish dumps. Even my friends here tell me it’s ok to throw my paddle-pop wrapper out the car window. I can’t… so I just hold it tight and wait till I get home. Growing up in Australia, those ‘emu hunts’ in primary school have willed my littering days away. Yet I suspect that even my household trash bin will just be dumped across the road for the cows to eat or worse still, burnt on the street…for the cows to eat. This is India. Love it or hate it. (#tii) As an Australian social worker volunteering with an NGO in Southern India I witness the large divide between the rich and poor of this incredibly colourful nation. I work with many children whose whole families have had to migrate from various parts of India due to the rapid effects of drought on their land and the significant urbanisation of major cities in the last 10 years. It turns out India has seen a boom in it’s industrial and technological trades a little later than it’s western neighbours and they are loving it. But India’s urban boom is threatened with westerners telling them they have to stop producing and polluting. The earth doesn’t like it. Sorry India…We made our big capitalist bucks, but you don’t get that chance. Just when things are getting good and you’re developing astronomically, your main source of energy is being taken away. It turns out fossil fuels are the cheapest form of energy for the developing world, especially as they try in earnest to develop the same standard of living as we have. So as one the most formidable countries in the developing world, India not only has the pressures of navigating a massive population but also has to figure out how to go green on the cheap. It’s interesting that the Turnbull government has reluctantly agreed on a 5% reduction in carbon emissions in the next five years. “Phew! Glad we got through that one boys.” They wipe their sweaty brows while developing countries are drowning, burning and trying to survive on scant resources. These countries are just trying to make a crust, while Eurocentric nations are slowly turning a baguette into organic multigrain sourdough (and throwing the crusts to their hobby cows). If the 2015 United Nations Climate Change Conference in Paris is truly the last attempt for international cooperation, leaders cannot just show and tell their contribution and sit back with folded arms. But how can mere human individuals promote serious teamwork? This brings me back to the children I work with here in India. Every day their parent’s lives are tied to corrupt building associations. They are bonded labourers—gypsies moving from construction to construction. These families have no hope of returning to their now desolate homeland and are not provided social security measures that protect their livelihood. Then there is India’s neighbour, low-lying Bangladesh, experiencing saltwater intrusion that poisons whole water supplies for entire villages. In our own backyard we see Australian farmers shooting all their cattle only to turn the gun on themselves under the shadow of unprecedented drought. This is human impact. Global warming is not just about penguins and polar bears. Climate change is a social justice issue. We live in a globalised world. The industrial revolution brought us here; and climate change is the consequence. No longer do we just neighbour cities, we neighbour nations. The leaders of Australia must be held accountable to all their neighbours including the ones just trying to keep their head above water. It simply won’t do for wealthy nations, such as Australia, to show the world their own country’s carbon reductions and sit back down. This summit can’t work as a set menu; it has to be a potluck dinner, a time for sharing, understanding and safeguarding. For the sake of our beautiful earth and the many diverse cultures of the human race, this time I hope and pray that the leaders of the world provide a resounding voice for the marginalised. This summit and our government must not stop at figures, but uphold the basic democratic and human rights principles that cradle modern society. The United Nations was created so that man-made and worldwide calamities could no longer grasp our world with such authority. Well, it turns out a world war with Mother Nature is knocking on our doorstep. Will we listen and respond? I hope so.   For more information please visit the below links.

    Black Friday Promotes Over-Consumption and Waste

    By Joseph Ramondeli

    Black Friday Promotes Over-Consumption and Waste               Every year Thanksgiving weekend is overshadowed by Black Friday and in recent years Cyber Monday as well. Thanksgiving is supposed to be a time when families can get together, even if it’s just for a day or dinner, to talk and reconnect. However every year more American’s are focused on shopping. Stores are now open by 8:00 pm on Thanksgiving Day resulting in people sitting at the dinner table with their families while browsing on their phones for the best deals that they hope to buy in a few hours.  This is just another example of how our modern, technologically advanced society is constantly becoming more materialistic. Aside from Black Friday overshadowing an American holiday and tradition, it is an annual example of how Americans over-consume and by doing so are very wasteful.  A huge fraction of purchased goods during Black Friday and Cyber Monday are things that people don’t need, they are things they think they need. Advertisements and social trends play a big role in the impact of this event (I refuse to call it a holiday) and in our consumption behavior in general.             Companies are tricking and forcing us to buy un-needed goods through the use of planned obsolescence and perceived obsolescence.  Planned obsolescence is disappointing because it refers to how companies purposely make products to only last a few years and by doing so force consumers to by new products from them every couple of years. The most common example of this is electronic devices. Apple creates a new IPhone every year so that once yours break “accidentally” there’s a brand new, more expensive one to purchase as a replacement. Not to mention that such companies stop making old models, forcing you to buy the newest model. On the other hand, perceived obsolescence is promoted by companies but ultimately results from our own social actions. Companies, through advertisements, constantly throw the promotion of new goods in our face. It’s almost impossible to go anywhere or do anything without seeing an advertisement of some sort. These advertisements tend to increase around the holiday season, hence the origin of Black Friday. The main reason such advertisements work is due to the social pressure we put on each other and ourselves. Everyone wants the next new model or brand and once a friend or family member purchases something then we are pressured and attracted to buying it as well. The biggest example of this is the fashion industry, where new trends come and go each season resulting in constant purchasing of new, unnecessary clothing. These companies are clearly getting the better of us based on the success of such events as Black Friday and Cyber Monday.             So why is over-consumption such a bad thing, why should we care if people waste there money on unnecessary goods? It’s simple: overconsumption leads to waste! One of the downfalls to the technological advancements of today’s world is that we create materials that cannot be found in our natural world. This means that when we throw something out in the garbage it will never decompose. Purchasing many of today’s consumer goods is bad enough because most cannot be recycled and will sit in landfills, but over-consumption takes this once step further in that we buy more than we need! We buy new clothes or new phones before our old ones are worn our or broken. By doing so we are creating more waste because we constantly thrown away products that are still functional and contribute the ever-growing amount of waste humanity has created on this planet. In order to help reduce the waste we create of course we should recycle and reuse as much as possible. However, I believe that the creation of waste should be stopped at its source, and that’s our consumer purchasing. Buying less and using goods to there fullest is a sure way to decrease waste. Resisting social pressure and advertisements is key to getting this accomplished. So next year put the phones away and turn the TV off at the dinner table during Thanksgiving, you don’t need them.
