Converting Trash to Energy

waste to energy

It is Europe’s new trend: creating energy from residential waste.  In previous posts, I have talked about the Copenhagen Summit, and the effects it has had on the US and Europe.  Just outside the city where this world conference convened, trash is brought to make energy.

In Denmark alone there are 29 plants, called incinerators.  Across Europe, there are over 400 incinerators.  In comparison, the U.S. only has 87 incinerators, all build more than 15 years ago.  The citizens of the country have embraced the technology.  In her article printed in the New York Times, Elizabeth Rosenthal focused on the Danish city of Horsholm.  It costs less to burn the trash at the incinerators than it does to use a land fill.  The energy created at the plant then goes directly to the community surrounding the plant.  Homeowners say the plant’s presents lowers their heating costs and increases their home value.

Here are some benefits of incinerators:

  • creates less climate-warming gases than landfills
  • creates 9 times more energy than landfills
  • cost less than maintaining landfills
  • Little odor

Even with these benefits, the U.S. is reluctant to build more incinerators.  Here’s why:

  • We have a lot of land to use for landfills
  • Belief that it will detract from the strong message for people to reduce waste and recycle
  • Cost of building (though some say that the cost would pay for itself over time by money saved)
  • Traditionally, trash disposal is a responsibility of the state/local governments, not the federal government

I feel that a lot of people are not aware of the use of incinerators, so I showed Rosenthal’s article to a Furman student to get her take on the use of waste-to-energy technology.  Here is what she said:

HOMESTAR program to encourage more "green" homes in US

Installing energy efficient products such as windows, lighting, water heaters, and other Energy Star products could be covered by the HOMESTAR program.
Installing energy efficient products such as windows, lighting, water heaters, and other Energy Star products could be covered by the HOMESTAR program.

In my last few blogs, I have shared with you the ins and outs of the Copenhagen Summit, and what the changes might mean for Europeans and Americans.  Now, President Obama has unveiled a new way to encourage Americans to make their homes more “green” while helping to put Americans back to work.

At the beginning of this month, Obama was in Savannah, Georgia to discuss a new program, called the HOMESTAR program.  HOMESTAR would give rebates to consumers who made changes to their homes to make them more energy efficient.  Here is what the program would do:

  • Give rebates directly to the consumers in two tiers
  • Tier 1: Silver Star Rebates of $1000-$1500 for projects such as insulation, duct sealing, water heaters, HVAC units, windows, roofing and doors
  • Tier 2: Gold Star Rebates of up to $3000 for performing a “home energy audit” and then making necessary improvements to reduce energy use by 20%
  • provide financing options for repairs

This program would offer new jobs for contractors, small businesses, and construction companies.  Plus, some of the energy efficient housing parts, such as windows, are manufactured here in the US.

The Obama Administration hopes that this program will be as successful as last year’s Cash For Clunkers— another program that gave money for living a more sustainable lifestyle.  Like HOMESTAR, the Cash For Clunkers program also helped to stimulate the economy by encouraging Americans to buy a car with a better fuel efficiency.

The 'Green' Standard

As students of Furman University, being ‘green’ has become the standard on which we strive to live by. One of the most crucial aspects of remaining green is being energy efficient, and in a world that is run on oil and other fossil fuels, it is important not to forget the finite characteristic of these fossil fuels. As the need for sustainable energy becomes more prevalent in the world, the spotlight has turned to more renewable energy sources, such as:

Examples of renewable energy sources
  • Sunlight
  • Wind
  • Tides
  • Geothermal

As these naturally replenishing energy sources becomes more viable, it is important that the United States makes policy considerations in regards to trading that would encourage or inhibit the production and initiation of renewable energy resources. Economic analysts say that these necessary trade policies will be the topic discussed during President Barack Obama‘s upcoming trip to Indonesia. The Indonesian Trade Minister, Mari Pangestu, “not[ed] that the United States has a ‘comparative advantage’ in a number of renewable energy areas”

For the United States to remain competitive and committed in the rapidly growing field of renewable energy, however, it is important that policies be enacted that allow for beneficial economic growth in these new markets. Recently, “Chinese manufacturers are entering the U.S. wind market under a joint venture led by Dallas investor Cappy McGarr,” with the U.S. Renewable Energy Group.

As the world enters into a new era of energy and politics, the role of the United States in the energy transformation will be decided by the policies enacted and the trade agreements made with other countries.

Nuclear Power as a solution?

Nuclear Power will receive $8 billion in federal guarantees
Nuclear Power will receive $8 billion in federal guarantees

In the wake of the 2009 U.N. Climate Change Conference, the United States begins to look toward its promises to reduce greenhouse gas emissions by 2020. To combat the rising rate of U.S. emissions and introduce new clean energy plans, President Barack Obama has granted over $8 billion in federal loans to go toward the construction of nuclear power plants in the United States. While this decision has been criticized by proponents of more renewable energy, such as wind and solar power, Obama stands his ground that “nuclear energy remains our largest source of fuel that provides no carbon emissions.”

The idea of nuclear power as an alternative energy source is not unheard of especially when looking on the international map. France supplies nearly 80% of their energy consumption through nuclear power, far greater than the 20% supplied by U.S. reactors. The Obama Administration hopes that the two new proposed reactors in Georgia will aid in the promise made at the Copenhagen Conference of reducing carbon emissions to 17% lower than they were in 2005. The construction will mark the first nuclear power plants in the U.S. in over 30 years.

If the United States is to be an integral global actor in the switch to more stable and reliable energy, then the introduction of nuclear power demonstrates a proactive approach to the encroaching global climate and energy issues.

Northern Europe Announces "Supergrid"

Energy resources

Nine European nations announced at the end of January they would enter into a project that would help them to capture renewable energy resources. This supergrid will connect different energy sources by cables running under the sea. The cables will connect energy including

The idea is that energy would be captured where it is available, and then could be channeled to a place where energy was needed.  For instance, if the wind farms were creating a lot of energy in England, but the solar panels in Germany were not capturing a lot of power, energy from England could be sent to Germany through the underwater cables.

The new grid system will help to reduce Europe’s dependence on fossil fuels, assisting in the EU’s goal to provide 20% of their energy from renewable resources by 2020.  The development of the grid will also create environmental-friendly jobs which will stimulate the European economy.  Participating nations are:

  • United Kingdom
  • Germany
  • France
  • Belgium
  • Netherlands
  • Luxembourg
  • Denmark
  • Sweden
  • Ireland

The estimated cost of the grid is $40 billion. And, it is hoped that this North Sea grid would be the first step towards a grid that would serve all of Europe.
