Now this is green energy

Photo microbial fuel cells or also known as moss.

Making those does have less of an environmental impact than solar panels. Another added benefit is that green roofs reduce the heat island effect, meaning less energy is needed to cool buildings/houses.

I wonder if GMO plants could make this more efficient, but the same old problem arises: the GMO moss will end up in the environment and the long term impact is an unknown.

Fascinating! I always wonder what is the energy cost of making solar panels. I know there is a lot in the silicon crystal manufacturing.

Difficult to say.

Difficult to say.

This phrase pretty well gives as close of an answer as any:

Crystalline silicon devices are approaching the theoretical limiting efficiency of 29.4% and achieve an energy payback period of 1–2 years

So does this mean we are going to have to mow our roofs as well?

What creatures eat moss?

 

[Homicidal_Squirrel]

Some faily large animals that you wouldn't want on your roof. Also, some small ones that you probably wouldn't want in your home.

 

[Scott DeWar]

Build a stronger roof! Mow much does a rain deer weigh? less then an elk?

 

[Kramodlog]

Or make GMO rabbits that lay eggs. They maintain the moss and produce food!

What are you going to do about the reindeer poop?
