glenn beck was on the radio at work today and they were talking bout energy cost and such. says milk up 100%from this time last year. eggs 33%, etc... and all these peeps calling in and complaining that the gov. or big buisness needs to do something. usdoe estimates that 40% of the energy used in this country is for powering residential homes. and yet, most peeps spend more on thier driveways than they do insulating thier homes. and doing it with 80 year old technologies.
