Landfill Gas: A Valuable Resource?
With all the bad news surrounding methane and landfills, one wouldn’t expect to hear about an innovative source of energy.
Trucks Reduce Emissions by 83%
Truck stop electrification is boosting fuel efficiency and minimizing dependence on foreign oil from idling trucks.
3 Reasons Manure is Becoming a Cash Crop
You know that times are changing when farmers look to manure as a valuable commodity. Pretty soon, manure from a herd may be more profitable than the beef itself. Manufactured fertilizers has tripled in price in the last year, driving farmers to look for alternatives.
Transportation Fuel Produced From Trash in World's Largest Plant in 2009
300 garbage collection trucks in California will soon be fueled by the same trash that they haul. Landfill gas will be

Solar Leases Make Cents
What if solar leases were available with electricity savings greater than the monthly charge?
Chicago Generates Twice the Energy for a Third of the Carbon
When generating electricity, roughly two-thirds of the energy is lost. Heat is created as a byproduct to spin turbines and later wastes away in cooling towers. Chicago has committed to produce 1.5 billion kilowatt hours of electricity by 2010 with a process call combined heat and power or cogeneration, which finds use for the generated heat. This process can be over 90% efficient.
