Mega scale solar thermal projects to generate “green electricity” is never going to be feasible because the constraints, limits and ethos are all stacked against it.
The maximum potential amount of solar energy falling on a square meter of land in the wilderness of Australia is 7 or even 8kWh per day.
Assuming a unrealistic 100% energy conversion efficiency rate and stack them against the amortized capital cost (assuming running input cost is zero, what will the cost-performance (returns) be?
Solar energy is not unlimited; it is constrained limits and this is one of the fundamental first principles that we should be aware of, always.
The ethos of converting solar energy into electricity so that we can continue to live our wanton energy guzzling lives and not making inconvenient adjustments to cut down our energy footprint will only get us back to square one.
Indeed, the Earth can supply all of our needs; never our greed.
If we, however, live within the Cycle of Sustainability and Renew-ability, even fossil fuel is a sustainable resource.
Alas, we are all caught up in the hurry to “progress” and “grow” our economies to the detriment of our larger meaning of quality living.
Fellow earthlings, Repent, Rethink, Reduce, Reuse and Recycle before we reach the tipping point of no return!
