The image shows panels that convert solar energy to electricity. This is an example of using renewable sources.
This is in contrast to something like coal energy which is nonrenewable. Coal is finite and will run out some day, unlike the sun's energy which won't run out any time soon. Sure it will eventually die off in about 5 billion years or so, but that timescale is much longer compared to the amount of coal is left. So this is a benefit to using renewable resources.
