How green is your cell phone tower?

In the developing world, where electric grids are less reliable, many cell phone towers have to generate their own electricity. With diesel generators, that means that energy costs can add up to 2/3 of the total maintenance costs. Theft and vandalism are also a big problem with these systems.

As a result of these high energy costs, many cellular providers in the Third World have adopted green power supplies. In addition to wind and solar power, some of these cell phone systems incorporate biodiesel.

Designers are also rethinking the traditional cell phone tower. In 2007, Ericsson introduced the Tower Tube – a self contained concrete tower that has less visual impact and a smaller carbon footprint. Since they use concrete instead of a steel structure, and have no need for a perimeter fence, these towers release approximately 20% less CO2 than conventional towers. Other companies are getting rid of cell towers entirely by using trees!



If you look closely, the cell towers near your house may already be using solar or wind backup power supplies. Here’s an example of a solar panel that powers weather monitoring equipment on a cell tower.

Cell towers can go hybrid solar-wind-diesel in the 3rd world and cell users can get a hand crank generator radio-cell phone charger. If USA cell phone users hand cranked their phones to charge, they would quickly realize the overwhelming luxury of all the electricity we have from utilities.
