On a planetary scale, gigawatts are nothing. The total amount of energy that Earth receives from the Sun is about 100,000,000,000 megajoules of energy every second, 99%+ of which gets dissipated as heat.
If this is about the climate, then it's important to remember that climate change and pollution ultimately are not a meaningful threat to Earth as a planet - both Earth and its life have been through far far worse[0][1][2][3]. They are only a threat to humans[4].
