Read the fruits of Tim Bowen's boundless energy in this blast of collocations.
Some people are fortunate enough to have a great deal of energy. This can be described as tremendous energy or boundless energy, as in 'His enthusiasm and boundless energy will be missed by everyone at the school’.
Too much energy can be described as excess energy or surplus energy, as in ‘Let the kids work off their excess energy with a few races.'
Energy that is associated with emotion is generally described as nervous energy, as in 'I expended a lot of nervous energy on the day of the wedding', and energy that is not expressed is pent-up energy, as in ‘Now is the time to release all that pent-up energy’.
If you have a lot of energy, you can be said to be bursting with energy or buzzing with energy. In that situation, you may need to release some energy or work it off, as in 'I need to work off all this surplus energy.
If, on the other hand, you don’t have much energy, you may want to save or conserve it, as in ' At the start of a marathon, runners are advised to run more slowly in order to conserve energy'.
When you have used up all your energy, you can be said to be drained of energy or lacking energy and if you need to get some from somewhere, you will need to summon up some energy, as in ‘We found it difficult to summon up the energy for one last attempt to reach the summit'.
