Energy Considerations for 2050



Fossil-fuel energy will deplete in the future; millions of years to
create that much cheap fuel
US oil production peaked about 1974; world energy will peak about
2009 or so
The US imports about 10 million barrels crude oil/day
Renewable energy will become mandatory, and our lifestyles may change
Transition to renewable energy must occur well before a crisis occurs

Why use Solar Energy?



Far from utility power lines; costly to extend lines
Provide backup power during utility outages

Minor glitch backup might be only for two minutes
Hurricane line damage may need two weeks to repair

Cleaner energy with no CO</span><span style=" font-family: 'Tahoma', 'Arial';

emissions
Self-satisfaction of using some free energy (but it costs money
to get it)
Greener than thou syndrome bragging rights

I just want it!
