Biden isn't the greatest orator obviously but his official position is he won't allow new fracking leases on public land (where about 10% of fracking in the US takes place). I have my doubts he can even get that through.
As far as a possible peace deal between Israel and Saudi Arabia, last I read Saudi Arabia wouldn't even consider it until Israel made peace with the Palestinians. Obama didn't have a good relationship with Netanyahu but still provided Israel a record amount of financial assistance at the time. I'd assume a Biden presidency would do the same.
