Subject: Can we store energy we make, instead of producing more energy than we need

I'm asking this question because we are creating a lot of energy which is 
going to waste, and also creating a lot of greenhouse gases which leads to 
climate change and global warming. Why can't we make energy when we need it 
and not just make energy because we can, if not we will slowly destroy the 
planet we life on because the ice caps would melt and sea levels to rise
