Climate and power

The proponents of climate change are facing a dilemma. They want to get rid of fossil fuels but they have no realistic replacement. To use wind and solar requires the mining of rare earths and environmentalist oppose that unless it is done in China. Meanwhile progress can be made by continuing to improve mileage and moving away from coal in power plants. This has allowed the US to reduce CO2 emission over the past 15 years by more than any other country. The use of natural gas for transportation would continue this downward trend since transportation accounts for 28% of all energy use in the USA. New and improved nuclear power plants could be built. Currently the US gets 20% of its power from nuclear which represents 50% of all carbon free energy. There are two nuke plants set to come on line next year. Solar currently provides 2% of power.
