The Internet is powered by vast banks of computers which eat up energy. That's expensive for the people who run these servers, and it has a cost to the earth, depending on how all the electricity is generated. Aaron Rallo is CEO of TSO Logic, which offers a software solution to this. Another company working to make the net more efficient is Joyent. Its chief technology office, Jason Hoffman, believes the demands are going to get so high on our digital systems -- given all the computer chips going into things -- that we'll need some big technological leaps.
