Litton house: electricity 100% from renewable sources

Yup, 100% of the electricity that we consume at our house is generated from renewable sources. Well, that's the net effect anyway. Our local electric company, TECO, has a program whereby one can purchase renewable energy 'blocks'. Each block costs US$5 per month and is equal to 200 kWh of electricity. Our average monthly use is currently 1400 kWh (more in summer and less in winter). So we have signed up to purchase 7 blocks per month. It's a bit silly, in a sense, that we'll be paying US$35 a month more each month for energy that ultimately costs less once one factors in the long-term costs to the planet. But that's OK. The way this program works in reality is that by purchasing 7 blocks of energy each month from renewable sources, TECO will route 1400 kWh of electricity (generated from solar / landfill gas / biomass sources) into the portion of the grid that serves our neighborhood.

My hope is that enough homes and businesses will sign on to these programs that eventually the bulk of the energy we use will be produced from renewable sources.
