Proposed Climate Change Legislation
80% below 1990 levels to ~ 1.2 billion metric tons by 2050
The Real Cost of Tackling Climate Change
• U.S. population is expected to be around 420 million by 2050.
• To meet the 80% below 1990 levels by 2050 we would have to
reduce U.S. emissions to ~1 billion metric tons or go from ~20
tons per capita to ~2.5 tons per capita.
• France and Switzerland that generate almost all their
electricity from non-fossil fuels are at about 6.5 tons per
capita.
• Replacing every existing coal plant with a natural gas plant
would still put us at twice the 2050 target.
• If everyone drove a Toyota Prius in 2050 the equivalent
transportation target would be overshot by 40%.

Insights from Recent EPRI Work
• The technical potential exists for the U.S. electricity sector to
significantly reduce its CO2 emissions over the next several
decades.
• No one technology will be a silver bullet – a portfolio of
technologies will be needed.
• Much of the needed technology is not available yet – substantial
R&D, demonstrations are required.
• A low-cost, low-carbon portfolio of electricity technologies can
significantly reduce the costs of climate policy.
Key Findings
EIA Analysis of Lieberman-Warner S.2191
“The electric power sector accounts for the vast majority of the emissions
reductions, with new nuclear, renewable, and fossil plants with CCS
serving as the key compliance technologies in most cases. Many
existing coal plants without CCS are projected to be retired early
because retrofitting with CCS technology is generally impractical.”
“If new nuclear, renewable, and fossil plants with CCS are not developed
and deployed in a timeframe consistent with the emissions reduction
requirements, covered entities are projected to turn to increased
natural gas use to offset reductions in coal generation, resulting in
markedly higher delivered prices of natural gas.”
