-it's a short answer question-
how does energy reduce human impact on climate change?

Clean or green energy helps in releasing lesser air pollution and lesser carbon dioxide. That contributes in lowing down global warming and subsequent disasters like tsunami because of glacier melting , more unexpected climate changes like unexpected long-period storms, flood, typhoons,  etc.

Hope this would help.

you are the source of the heat energy. you can minimize the heat energy by selecting the appropriate clothes to wear.
