You can never have "high level of energy throughout the day" everyday. A lot depends on your Food, Sleep, Time-of-the-day, Past Activities etc. That said you can have good high alertness, cheerfulness, positive mentality, energy for most of the day by following some simple disciplines. Here is mine;

1) From Hatha Yoga: Do Kapalabhati, Bhastrika, Nauli kriya, Mula Bandha, Uddiyana Bandha. All should be done gently without too much force. End with massaging the head lightly.

2) Loosen all your joints particularly hip/pelvic area and then do some stretches (Yoga asanas are recommended).

3) Do deep "Hindu squats" aka "Baithaks" (using the ball of the foot to push off the ground while getting up) and "Hindu Pushups" aka "Dand" in sequence. The squat raises the energy from the sole of the foot and the pushup conducts it through out the body.

4) Read Dr. Satchin Panda's book "The Circadian Code" (and watch his videos on Youtube; eg. https://www.youtube.com/watch?v=fciGNBN0nKM) and setup your daily activities in accordance with your circadian rhythm.
