Energy a view to next 10 years.
 In the United States, absent any policies Carbon capture and storage (CCS), would expect coal and natural gas to be lowest-cost options for future.
At $30 per ton of CO2, natural gas would become the most economic alternative for new-build power plants. This is where we expect CO2 costs may evolve over the next 10 years.
As the CO2 price increases, we would expect to see fuel switching from coal to natural gas.
At $60 per ton, natural gas is still very competitive. In addition, nuclear and wind are now competitive.
The cost of capturing solar energy in photovoltaic cells or concentrators remains generally unaffordable for large, commercial applications.
