KNOWLEDE SI POWER
But wisdom trumps all.
Depends on what you want to say: if someone withholds information from you in order to control you, information will be power. So is knowledge: it enables you to do a job to earn money, i.e gives you power. So both are right but in a different sense.
Both information and knowledge are power.
for exmple if you don,t have with something like job .So knowledge is very important.
Being well informed is the key to success. If you have the information, you have the knowledge.
Both are uncountable words.
