Sustainability
Sustainability
• In the 21st century, the world is facing a host of acute environmental problems that are generically known as
‘sustainability issues’
• These issues are complicated and interrelated. They are reported very often in the media (TV, websites).
Everyone have at least heard of them but may not appreciate their future implications
• Sustainability is about over consumption of the finite resources of the planet.
• When a resource is being used at a rate that is faster than that at which it can be replenished, there is a sustainability issue.

    Renewable Energy

    In recent decades, there has been an increased need to produce sufficient renewable energy to support global population growth. In response, it has become crucial to find socially responsible sustainable energy resources that offer energy security, reduce greenhouse gas (GHG) emissions, and do not compromise biodiversity or sustainability of existing resources. Despite efforts to reduce the amount of waste produced, a continually growing population limits the space available in landfills. Municipal and industrial waste biomass is often rich in organic matter, allowing for the creation and use of biofuels as an energy source. This organic matter can be used to synthesize ethanol, methanol, and biodiesel through the conversion of inorganic compounds into energy-producing organic carbon compounds. Moreover, unlike fossil fuels, which take millions of years to form, these organic carbon compounds are formed relatively quickly. Biofuel production from waste is beneficial as it allows for better management of landfill sites, and energy production from materials which typically cannot be recycled or composted. Most importantly, it allows for the reduction of significant amounts of methane produced from landfill gas emissions.…

    Using named examples, evaluate the contribution radical energy technologies and policies might make to a more sustainable energy future?

    With the world’s primary energy needs set to grow by 55% by 2030, and electricity consumption to double over the next few decades, managing future need is a global challenge, and one of the most significant of our time. The International Energy Authority (IEA) estimates that $22 trillion of new investment will be needed by 2030. At the same time, there is the global challenge of climate change and the need to develop cleaner sources of energy in order to improve the health of our environment. There are two main ways of achieving this; measures such as emissions controls, carbon trading and green taxation to encourage a reduction in energy consumption and an increase in energy efficiency, this known as a ‘carrot and stick’ approach. The alternative to this is to develop new and radical technologies that are sustainable and bring energy security.…

    School Shootings Must Stop.

    You are in the mall and someone yells everyone "'Get down!" Or I will shoot." Your first instinct is to hit the ground before shots are fired. Now imagine that in the school cafeteria. Scary, right? As scary as it sounds scenarios from horror movies are playing out in schools all over America. You are eating lunch in the cafeteria and a student enters the cafeteria and starts firing off a firearm. First instinct is to scream for help and get on the ground, but why are scenes like this taking place in the learning place. The place where we are told we are the safest, maybe even safer than home. If school is so much safer than home then why are school shootings on the rise? "Most of us already know that too many of our movies, television shows, music songs, and video games are filled with trash: grisly murder scenes, dismemberment and disembowelment, nonstop profanity, rape and torture scenarios" (Bennett par 14). By placing scenes like these in movies for the youth to see the media is causing America to become more violent than is needed. We must prevent violence in schools, solve violence in schools and violence needs to stop now.…

    Nonconventional Sources of Energy

    I chose an unorthodox global theme to research and learn more about, because much of society is clueless as to how we obtain some of our resources. I’ve always had an interest in the environment and how we as humans affect it. So it only makes sense that the topic I chose to discuss is nonconventional sources of oil and gas. The main two sources I wanted to better understand are Hydraulic Fracturing and Oil Sands. Some of these techniques for retrieving oil and gas are in effect presently and some are still being discussed as to whether or not they should be practiced. All in all, they are very controversial topics that bring about a lot of heated debate. My goal is to inform the reader and myself about some of the things that go on behind the curtains. I want to give insight to the processes of retrieving the oil and gas. I would also like to talk about the ethics of these practices. Of course, there are pros and cons to every situation. However, in this situation, I think the cons outweigh the pros. I will argue that although these nonconventional sources of oil and gas may seem necessary, they are wasteful and very destructive to the environment and should not be practiced. When I get into how these methods of retrieval work, the horrific side effects and dangers will be revealed. It will become clear that these are not sustainable practices. These nonconventional sources are slowly deteriorating the earth we live on and negatively impacting its inhabitants. We should be focusing more on the renewable sources of energy that will never run out rather than destroying our environment any further.…

    Urban Sustainability

    The program that I chose to implement into my hometown is “How to Build a Cooler City.” “From 1878 to 2005, Los Angeles temperatures rose 4 degrees on average, climbing from around 62 degrees to 66 degrees.” Urban areas such as Downtown Los Angeles are likely to rise 4 to 4.5 degrees within the next 10 years. My goal is to cut the cost of electric energy and make the city of Los Angeles a much cooler place. The first challenge I will have is to go to city council and try to get them to back up my project and me. The next step would be to get a budget from the city and start working. I can lower the temperature of Los Angeles by implementing green roofs across the city and in particular downtown Los Angeles. The other is to lay down permeable material throughout alleyways and select streets. Both of these solutions have been used in Chicago to help lower the physical temperature of the city. For example the City Hall building in Chicago is half a regular black top roof and the other half a green roof. When measuring the temperature the black topside of the roof was about 160 degrees Fahrenheit, when on the other side of the same building, the green roof side, and the temperature dropped to about 80 degrees Fahrenheit. That is an 80-degree difference. The reason the roofing is such an issue is because all that heat is trapped on top of the building and then moves into the building which makes the it much hotter inside which creates more use of air conditioning, energy, and electricity. The next goal would be to have a “save our city” fundraiser where we can raise money for the project. I truly believe that people will want to contribute and participate given that this will eventually save them money through the cost of electricity as well as the comfort of living will be more enjoyable when inside their homes and offices. To me the implementation of…

    Alternative Energy Sources - Essay

    What does a car, heater, and stove have in common? They are all powered by fuel sources. The most popular being fossil fuels. Fossil fuels are dead plant and animal matter that has been compressed and heated over millions of years. They are burned to create heat, which in turn creates energy. However, with heavy industrialization (agricultural and manufacturing), transportation, and personal energy use, our world’s fossil fuel supplies are rapidly depleting. Even more, fossil fuels pollute our environment. Scientists are on the search for alternative energy sources so the world can be weaned of its fossil fuel supply. Out of the many alternative fuel sources, I will be focusing on solar and wind power.…

    Green Power from Clean Power

    Green energy is energy that is produced in such a way as to minimize its negative impact on the environment. Traditional energy sources, most notably fossil fuels, produce greenhouse gases that are believed to be the primary cause of an effect known as global warming or climate change. Sources of green energy, such as solar, wind, geothermal, and hydro energy, are developed and promoted as alternative sources that make little or no contribution to climate change. Even nuclear energy is sometimes considered a green energy source, because some types of nuclear technology produce much less waste than oil and coal.…

    Renewable Energy

    Renewable energy is energy from natural resources such as sunlight, wind, rain, tides, and geothermal heat, these resources are naturally replenished. Renewable energy does not harm the environment or deplete any of our natural resources like fossil fuel. Renewable energy is not subject to sharp price changes because it comes from natural resources. Biomass is currently the largest U.S. renewable energy source with more than two hundred existing bio power plants providing energy for one point five million American homes, according to renewable energy specialist Davor Habjanec. The first time I heard the political differences about renewable energy was the last presidential debate. President Obama stated that he has and will continue to invest in renewable energy, like windmills and solar power. His opponent, Mitt Romney accused Obama of not using more fossil fuels found in America, from building a pipeline in Alaska to investing in oil and natural gas. Romney also claimed that the Obama administration was not expanding research of renewable energy. President Obama’s economic stimulus package included a number of incentives like thirty percent tax credit for renewable energy.…

    Alternative Energy

    What would it be like to live in the dark? Finding new forms of alternative energy has been a major concern throughout the world for the past several years. Currently, our main sources of energy are coal for electricity, and oil for transportation. Alternative energy, also known as renewable energy, is defined as energy derived from sources that do not use up natural resources or harm the environment. At the rate we are using these nonrenewable resources oil is scheduled to run out in 100 years, and coal in about 1000 years, which is why finding efficient forms of renewable energy is crucial to maintaining the current levels of fossil fuels.…
