Comparison of carbon fiber vs steel manufacturing costs

http://www.rmi.org/RFGraph-carbonfiber_vs_steel_manufacturing
Automotive manufacturing costs can be cut by 80% with carbon fiber-based autos vs. steel-based ones due to greatly reduced tooling and simpler assembly and joining. However, such cost savings are currently overshadowed with carbon fiber material prices upwards of $16/lb.

 

U.S. renewable energy potential

http://www.rmi.org/RFGraph-US_renewable_energy_potential
Considering budding technologies that could be commercially available in the future, the potential U.S. generation capacity from renewables is overwhelming. Wave and tidal generators, offshore deep-water wind farms, and enhanced geothermal power (which uses the Earth's heat but doesn’t require a natural steam source) are all in development and represent a huge potential energy resource.

 

Cost savings from running CHP

http://www.rmi.org/RFGraph-cost_savings_from_running_CHP
Buildings or industrial facilities that operate combined heat and power (CHP) generators purchase a fuel (typically natural gas) and use it to generate electricity onsite, capturing the waste heat for the facility’s heating demands. Whether or not the operator can generate electricity cheaper than they can buy it is dependent on the current costs of fuel and electricity as well as the efficiency of their unit, and is quantified by the spark spread.
