Depends on what you recall as "energy" if u define it as producing electricity or moving an object from place A to place B, of course recoverable sources with no carbon is the.
But if u want that "energy" for steel making, u have no choice but the good old coal.
Besides all, "total" C emission is more important than C emission in the service. For example for fabricating and effective electric car, u need to produce lots of Ni based batteries, causig so much C emission before even u start using it.
1- Soreness is not a sign of muscle buildup... You can also build more muscles without it 2- Try some dropsets (set to 200 make 12 reps, reduce to 180 instantly do 12 again and so of) 3- Try some pyrimides ( start with 150-160 do 12 reps, incerease by 10 reduce to 10 reps) 4- Try some negative reps (do the positive in 2-3 seconds do the negative in 10-30 seconds) 5- Use more free weight excercises 6- I feel that you are loosing many time on same machine. Do ur bench press for 3-5 sets. then do some flyes, peck-deck, crossovers etc 7- ASK A PRO FOR HELP, LET THEM MANAGE YOUR TRAINING PROGRAM.
