say you wanted to power the entire Earth with solar power I estimate you would need around oh a hundred and twelve thousand square kilometers of at least a moderately efficient photoviteic panels if that sounds like a lot that's because it is but it's also not because those panels could also all fit in just a little more than one percent of the Sah...

Questions & Answers

Q: What are the challenges of relying on solar power for the Earth's electricity needs?

Relying solely on solar power poses challenges related to grid management, storage, and distribution due to the intermittent nature of solar energy and the mismatch between production and consumption patterns.

Q: How does the 'duck curve' impact electricity grids and renewable energy sources?

The 'duck curve' highlights inefficiencies in grid management when solar power production peaks during the day but falls sharply in the evening, requiring a shift to other energy sources to meet peak demand.

Q: What are some solutions to storing excess renewable energy for future use?

Storage options like batteries, hydrogen fuel cells, mechanical energy (pumped hydroelectric storage), and thermal storage using molten salts offer ways to store excess renewable energy and maintain grid stability.

Q: How can collaboration and grid interconnectivity help address the challenges of decarbonizing electricity?

By connecting grids over wider areas and sharing electricity resources, regions can efficiently deliver renewable energy, reduce emissions, and overcome limitations associated with individual grid systems.

Summary & Key Takeaways

• Solar power has the potential to supply the entire Earth's electricity needs, but challenges arise due to grid inefficiencies and energy storage limitations.

• The fluctuating nature of solar and wind power creates grid management issues related to electricity demand and supply.

• Various storage options like batteries, hydrogen fuel cells, mechanical energy, and thermal storage offer solutions to store excess renewable energy for future use.
