1. I'm think about solar energy.It is a renewable power source and can replace non-renewable energy sources such as gas, oil, ... Solar energy is used for many things such as: home heating, cooking, ... Solar panels installed and can replace electricity in the home help us save more electricity money. However, using too much solar energy will heat the earth and change the climate, so we find many sources of renewable energy and use them in turn.
