“Delivering cleantech energy solutions for a sustainable future,
now.”
US Renewable Energy Consumption by SourceDOE/EIA Annual Energy Survey, 2006
1) 24.7 Quads of energy used by industry…of this 20% to 50% is lost in the form of waste heat (DOE)2) Conventional hydroelectric power.3) Fuel ethanol and biodiesel consumption, plus losses and co-products from the production of fuel ethanol and biodiesel. 4) Municipal solid waste from biogenic sources, landfill gas, sludge waste, agricultural byproducts, and other biomass. Through 2000, also includes non-renewable waste (municipal solid waste from non-biogenic sources, and tire-derived fuels).

Running in parallel, ET systems can be part of a larger generating solution where individual units can be taken off-line without affecting the performance of any other unit
or the system as a whole.

ET’s fuel-free, emission-free power systems are available now.
Recoverable heat: ≥200°F liquid, ≥400°F gas, 400°F – 1000°F exhaust
Cooling Source: water <80°F, air <90°F
Management with a desire to: • reduce emissions to power ratios,• increase plant efficiencies,• net greater profit.
