Modern Marvels : Renewable Energy.
Airs on Wednesday January 24 09:00 PM

In the young 21st Century, two realizations are dawning on the world's 
population: we are hopelessly dependent on petroleum, which is only going to 
get more expensive; and global warming, caused mainly by our burning of 
fossil fuels, will impact civilization in ways that we're only beginning to 
grasp. Stepping in to fight both of these massive problems are the rapidly 
evolving technologies that harness renewable energy. We will see how air, 
water, earth, and fire are transformed into clean, reliable sources of heat, 
electricity, and even automobile fuel. We'll take an in-depth look at the 
most proven and reliable sources: solar, wind, geothermal, biofuels, and 
tidal power. From the experimental to the tried-and-true, renewable energy 
sources are overflowing with potential... just waiting to be exploited on a 
massive scale. And unlike fossil fuels, they'll always be there.

Modern Marvels : Environmental Tech
Airs on Wednesday January 24 10:00 PM

>From the prairies of Saskatchewan to a Manhattan skyscraper we'll see the 
21st Century's cutting-edge "green" technologies in action. New technologies 
such as carbon sequestration and bioremediation take on our most daunting 
environmental crises, from global warming and deforestation to nuclear waste 
and resource scarcity. See how blue-green algae are converted into 
automotive biofuel and methane from decomposing garbage is turned into 
clean-burning natural gas. Finally, we'll see how trees and other natural 
environments can be used as engineering materials to control flooding and 
rejuvenate dying rivers.
