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:

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.
