WASHINGTON - People will be paying higher energy prices under a Senate bill to limit greenhouse gases, but how much will depend on how well the country can shift away from burning fossil fuels, an Energy Department analysis said Tuesday.

The Energy Information Administration said annual energy costs could increase on average of as little as $30 or as much as 10 times that much by 2020. The projected cost increases per household ranged from $76 a year more to as much as $723 a year more by 2030.


The agency said the difference depends on how successful the country will be in replacing significant amounts of energy production from coal and oil to nuclear power as well as solar and wind energy, and how successfully it adopts conservation measures.

Overall, the report said the U.S. economy will continue to grow, but at a lower pace.
