Cities Around the World Find Energy at Home: From Sun to Sewage

Ever stood in the middle of a big city and thought What a lot of energy! You’re right. Any thriving metropolis is teeming with energy – sun beating down; feet and cars bearing down; offal and detritus decomposing; and often, sea tides pulling and pushing.

At the turn of the 21st century, an untenable rise in the environmental and economic cost of fossil fuels has finally spurred research into the development of clean and renewable energy sources all around us.

Let the Sun Shine In

Whether it’s Greensboro, North Carolina, Boston, Massachusetts, or Sheffield, England, designs are afoot for net energy-producing houses that sell energy to the grid.

And if rooftops aren’t enough, Mayor Bloomberg wants solar on top of landfills.

Some of the Urban planning tools which are helping attain this include:

But wait – there’s much more!

  • Can You Say “Piezoelectricity”? That’s electricity from pressure: like millions of feet in a Tokyo subway station. Or cars on a road in Israel, where they are also working on applying this technology to railroads.
  • Turning the Tide: A new generation of hydroelectricity uses tidal turbines in rivers, such as New York’s East River.

In the Future? How about -

Bonus: making it where you use it, means less energy loss during transmission. It also means job creation.

Do you have ideas for using the liveliness of the city to generate energy?

    Thanks! – And who knew my planning degree would pay off in Scrabble? But seriously, I’m looking forward to a piezoelectric floor in my house so I won’t have to keep cycling to run this computer.
