But Anyhow: If we where to just do a calculation for the fun of it, and calculate how large ara we would need to cover with solar panels to produce 150 000 TWh pr. Year:
Using part of The dessert of Algeria we would only need an area of 240 km times 240 km with solar panels. So , a very small part of Algeria could power the whole of the globe with all energy needs.
In real life, I would say we could build a number of large scale solar plants around the world,. Make Hydrogen as fuel for ships and trucks. This could also be liquid fuel, where hydrogen is Converted to ammonia. Use batteries and Pumped Hydro to store energy.
Expand the electrical grid to interconnect the whole globe, making everything one grid. The sun always shines somewhere and the wind always blows somewhere. Distributed solar and wind must be part of the Solution.
I do not know about your calculation, I would have to check that. Assuming your are correct, we'd still need to generate an extra amount due to the losses. This is just for the US in 2015 where we see about a 60% loss, but it's the same situation for losses everywhere that there is a grid in use.
I say don't give on these alternatives, but don't claim they are anything more than a stop-gap. And at that point I say, I don't want a temporary solution as there is just no time left for profit-taking on temporary solutions. Let's get to the real long-term solution of atomic power.
The claim was made that the so-called renewable technologies can power our civilization. At this time, they do not.
Whether or not they will in the future remains to be seen. All these pages of debate pose a scenario that requires a host of new technologies, new efficiencies, new grid elements, new transportation, and there is the rub.
I will continue to press for the long-term solution to our planet - new nuclear designs that are small, distributed, and energy-dense.
This is the technology that can power all the changes we will need.
Let's put our resources to that solution!
