This week we’re talking about World Domination. Domination of energy production, that is. In the re-scrambled words of the wise and infamous Dr. Evil: “Why make Gigawatts when we can make…Terrawatts!”
Indeed, solar is on track to completely dominate electricity generation. Solar is growing faster than wind, nuclear and LNG ever did. Alternatives to solar such as nuclear fission, nuclear fusion, CO2 capture and sequestration (CCS), and CO2 direct air capture (DAC) are way too expensive and very slow to scale to meet our needs. And with batteries sited with solar, we’ve solved the problems of intermittency and power when the sun is down.
Costs for rooftop solar and storage are continuing to decline as manufacturing scale increases. According to the National Renewable Energy Lab (NREL), rooftop solar can meet 45% of our energy needs. The rest can be easily met with utility scale solar.
So as long as we aggressively pursue deployments of BOTH rooftop and utility solar and storage, there is no doubt in my mind that by 2050 our society will be almost completely powered by solar. For more about Solar Power World Domination, listen to the full podcast at The Energy Show.
