WASHINGTON - President Barack Obama says his 2017 budget proposal would double spending on research and development of clean energy by 2020.

Obama says new investments will be included to help the private sector create jobs faster, make clean energy more affordable and help renewable power replace "dirty fuels."

Obama made the announcement Saturday in his weekly radio and Internet address.

Administration officials say spending on clean energy R&D would increase from $6.4 billion this year to $12.8 billion by 2020.

Congress must go along with Obama's request, and that seems unlikely given hostility toward the president's climate change agenda by Republican lawmakers in charge of the House and Senate.

Obama plans to send the final budget proposal of his presidency to Capitol Hill on Tuesday.
