In the South West US, this reaches 30% capacity BEFORE any storage.
Add 4hr storage and we reach 50% capacity. This is true for about 50% (pure guess) of humanity that lives in sunny climates.
Even better, poorer/populous countries are often closer to the equator with even better solar conditions.
We are literally half-way to solving our climate problems.
Now, about those Windows updates...
- rakoo 8y agoClimate problems are not about price, they're about CO2 émissions. Turns out producing and installing batteries produces a lot of CO2, and they're not even enough on a large scale so they have to be complemented with more pilotable electricity, which unfortunately mostly is carbon-based. As long as we depend on those intermittent sources (that's the real name we should give them not to be confused with other renewable), we rely on carbon.

- rakoo 8y agoBatteries are mostly produced in countries where a huge portion of electricity comes from CO2 (http://www.worldstopexports.com/lithium-ion-batteries-exports-by-country/ http://www.worldstopexports.com/lithium-ion-batteries-export...). On top of that, each battery needs to be transported to its final destination, which is yet another source of pollution.
- lostmsu 8y agoI don't think this is a good argument. What you are describing is the chicken and egg problem. Once one part is solved, the other one is too.
